[0001] Related applications

[0002] This application claims priority to Chinese patent application No. 202422501396.X, filed on October 16, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of air treatment technology, and in particular to a dehumidifying rotor and a rotor dehumidification device. Background Technology

[0004] To meet the demands of the production process, the relative humidity in the production workshops of various processes in a battery factory needs to be controlled to meet environmental humidity management requirements. One relevant technology involves using rotary dehumidifiers to introduce fresh outdoor air, dehumidify it, and then discharge it into the room.

[0005] Rotary dehumidifiers utilize a dehumidifying rotor as the core dehumidification structure. The rotor is divided into an absorption zone and a regeneration zone. By rotating the rotor, these zones circulate alternately. The portion of the rotor in the absorption zone absorbs moisture from the fresh air, achieving dehumidification. The portion in the regeneration zone is dried with hot air for dehydration and regeneration. Currently, regenerating the dehumidifying rotor consumes a significant amount of energy.

[0006] Application content

[0007] The main purpose of this application is to propose a dehumidifying rotor and a rotor dehumidification device, which aims to reduce the energy consumption of dehumidifying rotor regeneration.

[0008] To achieve the above objectives, the dehumidifying impeller proposed in this application has a moisture absorption zone and a regeneration zone arranged circumferentially along the dehumidifying impeller, wherein the regeneration temperature of the regeneration zone is varied along the circumferential direction of the dehumidifying impeller.

[0009] The technical solution of this application divides the dehumidification rotor into a moisture absorption zone and a regeneration zone. By rotating the dehumidification rotor, the various areas of the rotor alternate between the moisture absorption zone and the regeneration zone. The part of the rotor located in the moisture absorption zone can dehumidify the airflow passing through the moisture absorption zone, while the part of the rotor rotating to the regeneration zone can be dried by hot air for dehydration and regeneration. By making the regeneration temperature different in different locations in the regeneration zone, only a local area of ​​the regeneration zone can be heated to a high temperature, thus avoiding the need to heat the entire regeneration zone to a high temperature, thereby reducing the energy consumption of the dehumidification rotor regeneration process.

[0010] According to some embodiments of this application, the regeneration zone includes a plurality of regeneration processing zones arranged circumferentially, and the regeneration temperature of the plurality of regeneration processing zones is set to decrease along the rotation direction of the dehumidifying impeller.

[0011] This setup involves subjecting each regeneration zone to high-temperature treatment first, removing most of the surface moisture and carrying the moisture from the inner layer of the dehumidifying rotor to the surface. When the regeneration zone then rotates to a lower-temperature area, the moisture from the inner layer has already moved to the surface, allowing for effective drying at a lower temperature to achieve regeneration. Furthermore, the lower temperature in the downstream regeneration zone results in a relatively lower temperature in the area that enters the desiccant zone after regeneration. This reduces the temperature difference between the desiccant zone and the airflow flowing towards it, minimizing the heat loss and reducing energy waste.

[0012] According to some embodiments of this application, the dehumidifying impeller has a first surface and a second surface disposed opposite to each other along its axial direction, and the aperture of the mesopores of the dehumidifying impeller is reduced along the direction from the first surface to the second surface;

[0013] The air inlet of the moisture absorption zone is located on the first surface, and the air inlet of the regeneration zone is located on the second surface.

[0014] In this configuration, during dehumidification, the airflow first passes through the layer with larger mesopores near the first surface. Due to the larger pores, the specific surface area is increased, allowing more moisture in the airflow to be adsorbed in this layer. As the airflow gradually flows towards the second surface, it flows into the layer with smaller mesopores, where smaller water molecules can also be adsorbed by the dehumidification rotor, improving the dehumidification effect. During regeneration in the regeneration zone, the regeneration air first contacts the layer with smaller mesopores for heat exchange, allowing moisture from that layer to reach the surface area with larger mesopores. Dehydration in the surface area is relatively easier, and even if the regeneration air cools down after passing through the previous layer, it can still effectively remove moisture from the surface area, resulting in better dehydration and regeneration in the first regeneration zone.

[0015] According to some embodiments of this application, the dehumidifying impeller includes a first adsorption layer and a second adsorption layer stacked together, wherein the mesopores of the first adsorption layer are larger than the mesopores of the second adsorption layer, and the thickness of the first adsorption layer is greater than the thickness of the second adsorption layer.

[0016] In this configuration, the dehumidification rotor can be formed by stacking adsorption layers with different mesopore sizes, which is easy to prepare. Furthermore, the thickness of the adsorption layer with smaller mesopores, which is more difficult to dehydrate, can be set relatively thin, reducing the regeneration difficulty of the dehumidification rotor and helping to reduce the regeneration energy consumption of the dehumidification rotor.

[0017] This application also proposes a rotary dehumidifier, comprising:

[0018] Dehumidification channel;

[0019] The regeneration channel, which branches off to provide multiple primary regeneration pipelines; and

[0020] The dehumidification module includes a rotatable primary dehumidification wheel. The primary dehumidification wheel has a first moisture absorption zone and a first regeneration zone arranged circumferentially thereon. The first moisture absorption zone is located in the dehumidification channel. The first regeneration zone has a plurality of first regeneration processing zones arranged circumferentially along the primary dehumidification wheel.

[0021] Each of the multiple primary regeneration pipelines corresponds one-to-one with a number of the first regeneration treatment zones, and the regeneration air temperature of at least two of the primary regeneration pipelines is different.

[0022] The technical solution of this application involves branching the regeneration channel for rotor regeneration in the rotary dehumidifier into multiple primary regeneration pipelines. Each primary regeneration pipeline passes through a first regeneration processing zone. During regeneration in the first regeneration zone, as the primary dehumidifier rotor rotates, each first regeneration processing zone sequentially passes through each primary regeneration pipeline, allowing for multiple dehumidification processes and improving regeneration efficiency. Simultaneously, the regeneration air temperature varies in each primary regeneration pipeline, meaning that only a portion of the regeneration air in some pipelines is heated to a high temperature. This eliminates the need for all areas of the regeneration zone to use high-temperature regeneration air for drying and regeneration, thereby reducing energy consumption during the dehumidifier rotor regeneration process.

[0023] According to some embodiments of this application, along the rotation direction of the primary dehumidification impeller, the regeneration air temperature of the multiple primary regeneration pipelines is set to decrease.

[0024] In this configuration, during the regeneration process in the first regeneration zone, as the primary dehumidifying rotor rotates, the regeneration processing area within the first regeneration zone first rotates to align with the primary regeneration pipeline where the airflow temperature is higher. This allows the higher-temperature airflow to dehumidify and remove most of the moisture, and moisture near the inlet of the first regeneration zone is moved to the surface area near the outlet. The first regeneration zone then rotates to align with the primary regeneration pipeline where the airflow temperature is relatively lower, undergoing dehumidification again. Since the moisture has already been moved to the surface by the upstream high-temperature airflow, drying at a lower temperature is sufficient to remove moisture and achieve regeneration. This configuration requires only localized heating of the first regeneration zone, reducing energy consumption during regeneration. Furthermore, because the airflow temperature downstream of the rotation direction is lower, the temperature of the regenerated rotor is also relatively lower. When the regenerated rotor rotates to the first moisture absorption zone, the temperature difference between it and the airflow in the dehumidification channel decreases, reducing the offsetting effect of heat and cold between the first moisture absorption zone and the airflow, thus minimizing energy waste.

[0025] According to some embodiments of this application, the primary dehumidifying impeller has a first surface and a second surface disposed opposite to each other along its axial direction, and the mesopores of the primary dehumidifying impeller are reduced in size along the direction from the first surface to the second surface;

[0026] The air inlet of the first moisture-absorbing zone is located on the first surface, and the air inlet of the first regeneration zone is located on the second surface.

[0027] In this configuration, during dehumidification, the airflow first passes through the layer with larger mesopores near the first surface. Due to the larger pores, the specific surface area is increased, allowing more moisture in the airflow to be adsorbed in this layer. As the airflow gradually flows towards the second surface, it flows into the layer with smaller mesopores. Smaller water molecules in the airflow can also be adsorbed by the primary dehumidification rotor, improving the moisture absorption effect. During regeneration in the first regeneration zone, the regeneration air first contacts the layer with smaller mesopores for heat exchange, allowing moisture from this layer to reach the surface area with larger mesopores. Dehydration in the surface area is relatively easier, and even if the regeneration air cools down after passing through the previous layer, it can still effectively remove moisture from the surface area, resulting in better dehydration and regeneration in the first regeneration zone.

[0028] According to some embodiments of this application, the primary dehumidification impeller includes a first adsorption layer and a second adsorption layer stacked together, wherein the mesopores of the first adsorption layer are larger than the mesopores of the second adsorption layer, and the thickness of the first adsorption layer is greater than the thickness of the second adsorption layer.

[0029] In this configuration, the primary dehumidification rotor can be formed by stacking adsorption layers with different mesopore sizes, which is easy to prepare. Furthermore, the thickness of the adsorption layer with smaller mesopores, which is more difficult to dehydrate, can be set relatively thin, reducing the regeneration difficulty of the primary dehumidification rotor and helping to reduce the regeneration energy consumption of the primary dehumidification rotor.

[0030] According to some embodiments of this application, the rotary dehumidifier further includes a first processing air duct, the two ends of which are respectively connected to the dehumidification duct and the regeneration duct;

[0031] The connection point between the first processing air duct and the regeneration duct is located upstream of the first regeneration zone, so as to introduce part of the processing air in the dehumidification duct into the regeneration duct.

[0032] This setup introduces a portion of the processing air from the dehumidification channel into the regeneration channel as regeneration air, which increases the volume of regeneration air and improves the utilization rate of the processing air.

[0033] According to some embodiments of this application, the dehumidification channel has a first connection position located upstream of the first moisture absorption zone, and the first processing air channel is connected to the first connection position. This arrangement allows a portion of the processing air upstream of the primary dehumidification impeller in the dehumidification channel to be directed into the regeneration channel as regeneration air.

[0034] According to some embodiments of this application, the dehumidification module further includes a secondary dehumidification impeller, the secondary dehumidification impeller having a second moisture absorption zone and a second regeneration zone arranged circumferentially thereon;

[0035] Along the flow direction of the airflow in the dehumidification channel, the second moisture absorption zone is located downstream of the first moisture absorption zone.

[0036] This setup, with its two dehumidifying impellers, dehumidifies the airflow multiple times, thus improving the dehumidification effect.

[0037] According to some embodiments of this application, the second regeneration zone includes a plurality of second regeneration processing zones arranged circumferentially along the secondary dehumidification rotor, and the regeneration channel is provided with a plurality of secondary regeneration pipelines, each of the secondary regeneration pipelines passing through one second regeneration processing zone.

[0038] In this configuration, each secondary regeneration pipeline in the regeneration channel passes through a secondary regeneration treatment zone. While the first regeneration zone is being regenerated, as the secondary dehumidification wheel rotates, each secondary regeneration treatment zone passes through each secondary regeneration pipeline in sequence, allowing for multiple dehumidification processes to improve the regeneration effect.

[0039] According to some embodiments of this application, the regeneration air temperature of the multiple secondary regeneration pipelines is set to decrease along the rotation direction of the secondary dehumidification impeller.

[0040] In this configuration, during regeneration in the first regeneration zone, as the secondary dehumidification rotor rotates, the regeneration zone in the second regeneration zone first rotates to align with the secondary regeneration pipeline where the airflow temperature is higher. This allows the higher-temperature airflow to remove most of the moisture, and moisture near the inlet of the second regeneration zone is moved to the surface area near the outlet. The second regeneration zone then rotates to align with the secondary regeneration pipeline where the airflow temperature is relatively lower, undergoing dehumidification again. Since the moisture has already been moved to the surface by the upstream high-temperature airflow, drying at a lower temperature is sufficient to remove moisture and achieve regeneration. This configuration only requires localized heating of the second regeneration zone, reducing energy consumption during regeneration. Furthermore, because the airflow temperature downstream of the rotation direction is lower, the temperature of the regenerated rotor is also relatively lower. When the regenerated rotor rotates to the second absorption zone, the temperature difference between it and the airflow in the dehumidification channel decreases, reducing the heat cancellation between the second absorption zone and the airflow, thus minimizing energy waste.

[0041] According to some embodiments of this application, along the rotation direction of the primary dehumidification rotor, the first regeneration treatment zone adjacent to the first moisture absorption zone is a first sub-zone;

[0042] Along the rotation direction of the secondary dehumidification rotor, the second regeneration treatment zone adjacent to the second moisture absorption zone is the second sub-zone, and the area of ​​the first sub-zone does not exceed the area of ​​the second sub-zone.

[0043] In this setup, because the dehydration difficulty of the secondary dehumidification rotor is greater than that of the primary dehumidification rotor, the area of ​​the high-temperature dehumidification zone of the secondary dehumidification rotor can be increased to achieve a better dehydration and regeneration effect. For the primary dehumidification rotor, which is relatively easier to dehydrate, the area of ​​the high-temperature regeneration zone can be appropriately reduced to lower the energy consumption during the regeneration of the primary regeneration zone.

[0044] According to some embodiments of this application, the mesopores in the secondary dehumidification rotor are smaller than at least a portion of the mesopores in the primary dehumidification rotor.

[0045] In this setup, the airflow passes through a primary dehumidification impeller and a secondary dehumidification impeller in sequence for dehumidification. The primary dehumidification impeller can absorb most of the moisture in the airflow, while the secondary dehumidification impeller with its small pores further dehumidifies the airflow. This prevents smaller water molecules in the airflow from flowing through the secondary dehumidification impeller, ensuring a better dehumidification effect.

[0046] According to some embodiments of this application, the diameter of the secondary dehumidification impeller is larger than the diameter of the primary dehumidification impeller.

[0047] In this configuration, the secondary dehumidification impeller has a large specific surface area, which can improve the moisture absorption capacity of the secondary dehumidification impeller, so as to ensure that the airflow has a good dehumidification effect after passing through the primary and secondary dehumidification impellers in sequence.

[0048] According to some embodiments of this application, the thickness of the secondary dehumidification impeller is less than the thickness of the primary dehumidification impeller.

[0049] This setup reduces the thickness of the secondary dehumidification impeller, making it easier for the moisture adsorbed by the secondary dehumidification impeller to be released with the regeneration air, thus facilitating dehydration and regeneration in the second regeneration zone.

[0050] According to some embodiments of this application, the second regeneration zone is located upstream of the first regeneration zone along the flow direction of the airflow in the regeneration channel.

[0051] In this configuration, the regenerated airflow used to regenerate the second regeneration zone is redirected to the first regeneration zone for regeneration, which improves the utilization rate of airflow. Furthermore, the regenerated air temperature after regeneration in the second regeneration zone is relatively high, which reduces the energy consumed to raise the regenerated air temperature when regenerating the first regeneration zone.

[0052] According to some embodiments of this application, the dehumidification channel has a second connection position located downstream of the second moisture absorption zone;

[0053] The rotary dehumidifier includes a second processing air channel that connects the second connection position and the regeneration channel. The connection position between the second processing air channel and the regeneration channel is located upstream of the second regeneration zone.

[0054] This configuration, through a second processing air duct, directs the processed air from the dehumidification channel, which has undergone multi-stage dehumidification, to the second regeneration zone for regeneration treatment, thereby improving the utilization rate of the processed air in the dehumidification channel.

[0055] According to some embodiments of this application, the dehumidification channel has a third connection position located between the first moisture absorption zone and the second moisture absorption zone;

[0056] The rotary dehumidifier also includes a third processing air duct that connects the third connection position and the regeneration channel. The connection position of the third processing air duct and the regeneration channel is located upstream of the second regeneration zone.

[0057] This setup, through a third processing air duct, directs the processed air, after being dehumidified by the primary dehumidifier rotor, to the second regeneration zone, thereby improving the utilization rate of the processed air in the dehumidification duct.

[0058] According to some embodiments of this application, along the rotation direction of the secondary dehumidification impeller, the secondary dehumidification impeller further includes a second cooling zone located between the second regeneration zone and the second moisture absorption zone, and the third processing air duct passes through the second cooling zone.

[0059] This configuration allows the airflow in the third processing air duct to absorb heat from the second cooling zone. This not only raises the temperature of the airflow in the third processing air duct, thereby reducing the energy consumed to increase the temperature of the regenerated air, but also accelerates the cooling efficiency of the second cooling zone, reduces the temperature difference between the airflow flowing to the second moisture absorption zone and the second moisture absorption zone, thereby reducing the offsetting effect of heat and cold and reducing energy waste.

[0060] According to some embodiments of this application, the regeneration channel further includes a mixing duct, and multiple primary regeneration ducts are connected to the outlet end of the mixing duct, with the first air inlet located in the mixing duct.

[0061] Using the above method, the airflow flowing to the first regeneration zone in the regeneration channel is first mixed evenly in the mixing duct before being distributed to each primary regeneration duct, so that the airflow distribution in each primary regeneration duct is uniform and each primary regeneration zone has a good regeneration effect.

[0062] According to some embodiments of this application, the rotary dehumidifier includes a first heating structure disposed in the mixing duct.

[0063] This setup utilizes a first heating structure to heat the regenerated air in the mixing channel before distributing it to each primary regeneration pipeline. This increases the temperature of the regenerated air, improves the regeneration effect in the first regeneration zone, and reduces the number of heating structures required in the primary regeneration pipelines.

[0064] According to some embodiments of this application, the multiple primary regeneration pipelines include a first regeneration pipeline and a second regeneration pipeline arranged sequentially along the rotation direction of the primary dehumidification impeller;

[0065] The rotary dehumidifier further includes a second heating structure located on the first regeneration pipeline. The second regeneration pipeline may not have a heating structure, or the second regeneration pipeline may have a third heating structure. The heating power of the third heating structure is less than that of the second heating structure.

[0066] This configuration, by incorporating a second heating structure within the first regeneration pipeline to raise the gas temperature, allows for independent control of the gas flow temperature within the first regeneration pipeline, providing greater flexibility in temperature control. A third heating structure with lower heating efficiency can be incorporated into the second regeneration pipeline to control its gas flow temperature and simultaneously raise the gas temperature within the second regeneration pipeline. This allows for effective and flexible control of the heating power of both the first and second heating components based on actual needs, enhancing the flexibility of temperature regulation.

[0067] According to some embodiments of this application, the rotary dehumidifier further includes an indoor air duct, which is connected to the regeneration duct;

[0068] The connection point between the indoor air duct and the regeneration duct is located upstream of the first regeneration zone.

[0069] This setup utilizes relatively dry indoor air as regenerated air to dry and regenerate the dehumidifier's regeneration zone. This indoor air can be exhausted outdoors through the exhaust vent in the regeneration channel. In other words, the rotary dehumidifier can simultaneously introduce fresh air and exhaust indoor air to balance indoor air pressure and humidity, maintaining stable indoor air pressure and humidity without requiring a separate indoor air exhaust system, making it convenient to use. Furthermore, it allows for the reuse of low-humidity return air; the indoor air has a certain temperature, reducing the energy consumed to raise the temperature of the regenerated air.

[0070] According to some embodiments of this application, the indoor air duct includes two return air ducts, one of which is connected to the regeneration duct, and the other is connected to the dehumidification duct.

[0071] In this configuration, the indoor air duct can either guide relatively low-humidity indoor air into the regeneration duct as regenerated air, or guide indoor air into the dehumidification duct to mix with the airflow in the dehumidification duct. This can increase the airflow in the dehumidification duct, or use the indoor air to reduce the humidity of the airflow in the dehumidification duct.

[0072] According to some embodiments of this application, the rotary dehumidifier further includes a fresh air duct, which is connected to the regeneration duct. Along the flow direction of the airflow in the regeneration duct, the connection point between the fresh air duct and the regeneration duct is located upstream of the first regeneration zone.

[0073] This setup allows for the use of fresh outdoor air to dry and regenerate the first regeneration zone of the primary dehumidifier rotor, thereby increasing the volume of regeneration air and improving the regeneration effect.

[0074] According to some embodiments of this application, the dehumidification module further includes a condensation module disposed in the dehumidification channel.

[0075] This setup utilizes a condenser module to cool the airflow in the dehumidification channel and causes condensation to form, thereby improving the dehumidification capacity of the rotary dehumidifier. Attached Figure Description

[0100] To meet the demands of the production process, the relative humidity in the production workshops of various processes in a battery factory needs to be controlled to meet environmental humidity management requirements. One relevant technology involves using rotary dehumidifiers to introduce fresh outdoor air, dehumidify it, and then discharge it into the room.

[0101] Rotary dehumidifiers utilize a dehumidifying rotor as the core dehumidification structure. The rotor is divided into an absorption zone and a regeneration zone. By rotating the rotor, these zones circulate alternately. The portion of the rotor in the absorption zone absorbs moisture from the fresh air, achieving dehumidification. The portion in the regeneration zone is dried with hot air for dehydration and regeneration. Currently, regenerating the dehumidifying rotor consumes a significant amount of energy.

[0102] Based on the above problems, please refer to Figure 1. This application proposes a dehumidifying impeller 300. The dehumidifying impeller 300 has a moisture absorption zone 301 and a regeneration zone 302 arranged circumferentially along the dehumidifying impeller 300. The regeneration temperature of the regeneration zone 302 is set to vary along the circumferential direction of the dehumidifying impeller 300.

[0103] The dehumidifying rotor 300 proposed in this application has a moisture absorption zone 301 and a regeneration zone 302. By rotating the dehumidifying rotor 300, the various regions of the dehumidifying rotor 300 alternately circulate between the moisture absorption zone 301 and the regeneration zone 302. The part of the rotor located in the moisture absorption zone 301 can dehumidify the airflow passing through the moisture absorption zone 301, while the part of the rotor rotating to the regeneration zone 302 can be dried by hot air for dehydration and regeneration. In the embodiments of this application, the regeneration temperature is made different at different locations in the regeneration zone 302, so that only a local area of ​​the regeneration zone 302 can be heated to a high temperature, without heating the entire regeneration zone 302 to a high temperature, thereby reducing the energy consumption of the dehumidifying rotor 300 regeneration process.

[0104] Optionally, when using the dehumidifying impeller 300, the regeneration temperature of the regeneration zone 302 can be set to decrease or increase along the rotation direction of the dehumidifying impeller 300; or the high-temperature zone and the low-temperature zone can be set alternately, which is not limited here.

[0105] In some embodiments, along the rotation direction of the dehumidifying impeller 300, the dehumidifying impeller 300 also includes a cooling zone 303 located between the regeneration zone 302 and the moisture absorption zone 301.

[0106] In this embodiment, the dehumidifying impeller 300 also includes a cooling zone 303. It is understood that after the regeneration process is performed using regeneration air, the temperature of the impeller located in the regeneration zone 302 rises. At this time, the regenerated area is first turned to the location of the cooling zone 303 to pre-cool the impeller and prevent the temperature of the impeller from being too high after it turns to the moisture absorption zone 301, which would affect the moisture absorption effect.

[0107] According to some embodiments of this application, the regeneration zone 302 includes a plurality of regeneration processing zones 3021 arranged circumferentially, and the regeneration temperature of the plurality of regeneration processing zones 3021 is set to decrease along the rotation direction of the dehumidifying impeller 300.

[0108] In this embodiment, each regeneration treatment zone 3021 is first subjected to high-temperature treatment to remove most of the surface moisture and to bring the moisture located in the inner layer of the dehumidification rotor 300 to the surface. When the regeneration treatment zone 3021 then rotates to a lower-temperature area, since the inner layer moisture has already moved to the surface, drying at a lower temperature can effectively remove moisture and achieve regeneration. Furthermore, because the regeneration treatment zone 3021, located downstream in the rotation direction, has a lower temperature, the temperature of the area entering the moisture absorption zone 301 after regeneration is also relatively low. This reduces the temperature difference between the moisture absorption zone 301 and the airflow flowing towards it, minimizing the heat-cold cancellation between the moisture absorption zone 301 and the airflow, thus reducing energy waste.

[0109] Referring to Figure 8, according to some embodiments of this application, the dehumidifying impeller 300 has a first surface and a second surface disposed opposite to each other along its axial direction. Along the direction from the first surface to the second surface, the aperture of the mesopores 316 of the dehumidifying impeller 300 is set to decrease. The air inlet end of the moisture absorption zone 301 is located on the first surface, and the air inlet end of the regeneration zone 302 is located on the second surface.

[0110] In this embodiment, the direction from the first surface of the dehumidifying impeller 300 to the second surface is the moisture absorption direction of the dehumidifying impeller 300. The dehumidifying airflow enters the moisture absorption zone 301 from the first surface, and the moisture in the airflow is absorbed by the dehumidifying impeller 300. The dehumidified airflow then flows out from the second surface. The direction from the second surface to the first surface is the dehydration direction of the dehumidifying impeller 300. Regeneration air flows from the second surface into the regeneration zone 302, carrying away the moisture absorbed in the regeneration zone 302, and then flows out from the first surface.

[0111] Using the aforementioned rotor structure, during airflow dehumidification, the airflow first passes through the layer with larger mesopores 316 near the first surface. Due to the larger mesopores 316, the specific surface area is increased, allowing more moisture in the airflow to be adsorbed in the layer near the first surface. As the airflow gradually flows towards the second surface, it flows into the layer with smaller mesopores 316, where smaller water molecules can also be adsorbed by the dehumidification rotor 300, improving the moisture absorption effect. During regeneration in the regeneration zone 302, the regeneration air first contacts the layer with smaller mesopores 316 for heat exchange, allowing moisture in this layer to reach the surface area with larger mesopores 316. Dehydration of the surface area is relatively easier, and even if the temperature of the regeneration air decreases after passing through the previous layer, it can still effectively remove moisture from the surface area, resulting in better dehydration and regeneration of the first regeneration zone 302.

[0112] Referring to Figure 8, according to some embodiments of this application, the dehumidifying impeller 300 includes a first adsorption layer 314 and a second adsorption layer 315 stacked together. The mesopores 316 of the first adsorption layer 314 are larger than the mesopores 316 of the second adsorption layer 315, and the thickness of the first adsorption layer 314 is greater than the thickness of the second adsorption layer 315.

[0113] In this embodiment, the dehumidifying rotor 300 can be formed by stacking adsorption layers with different mesopore sizes 316, which is easy to prepare. Furthermore, the thickness of the adsorption layer with smaller mesopores 316, which is more difficult to dehydrate, is set to be relatively thin, reducing the regeneration difficulty of the dehumidifying rotor 300 and helping to reduce the regeneration energy consumption of the dehumidifying rotor 300. Of course, the dehumidifying rotor 300 may also include other adsorption layers, which are not limited here.

[0114] Referring to Figures 2 to 5, this application also proposes a rotary dehumidifier 100, which includes a dehumidification channel 1, a regeneration channel 2, and a dehumidification module 3. The regeneration channel 2 is branched with multiple primary regeneration pipelines 21. The dehumidification module 3 includes a rotatable primary dehumidification rotor 31, which has a first moisture absorption zone 311 and a first regeneration zone 312 arranged circumferentially thereon. The first moisture absorption zone 311 is located in the dehumidification channel 1, and the first regeneration zone 312 has multiple first regeneration processing zones 3121 arranged circumferentially along the primary dehumidification rotor 31. The multiple primary regeneration pipelines 21 correspond one-to-one with the multiple first regeneration processing zones 3121, and the regeneration air temperature of at least two primary regeneration pipelines 3121 is different.

[0115] In this embodiment, the rotary dehumidifier 100 is provided with at least one dehumidifying rotor 300, which is a primary dehumidifying rotor 31. The primary dehumidifying rotor 31 has a first moisture absorption zone 311 and a first regeneration zone 312 distributed circumferentially. It should be noted that the rotary dehumidifier 100 may be provided with multiple dehumidifying rotors 300. The primary dehumidifying rotor 31 may be the first dehumidifying rotor 300 along the dehumidification path, or it may be the second, third, or other dehumidifying rotor 300.

[0116] The rotary dehumidifier 100 includes a dehumidification channel 1 for introducing fresh outdoor air. The dehumidification channel 1 has a fresh air inlet 11 for receiving fresh outdoor air and an exhaust outlet 12 for discharging dehumidified airflow. In practical applications, the exhaust outlet 12 is connected to the indoor environment to discharge the dehumidified airflow into the room. One or more fans 9 can be installed in the dehumidification channel 1 to generate suction for drawing in fresh outdoor air and to provide power for the airflow to move within the dehumidification channel 1. When the airflow flows along the dehumidification channel 1 and passes through the first-stage dehumidification rotor 31, the moisture in the airflow is adsorbed in the first absorption zone 311, thereby achieving the effect of dehumidifying the airflow. Optionally, the rotary dehumidifier 100 also includes a filter 10 installed at the fresh air inlet 11 to filter the introduced fresh air, removing dust or other impurities and preventing dust and other impurities from adsorbing onto the dehumidification rotor and other structures of the rotary dehumidifier 100.

[0117] The regeneration channel 2 in the rotary dehumidifier 100 is used to supply regeneration airflow. The regeneration channel 2 passes through the first regeneration zone 312 of the primary dehumidifier rotor 31, allowing the regeneration air to dry the adsorption medium in the first regeneration zone 312, thus dehydrating and regenerating the adsorption medium. After passing through the first regeneration zone 312, the regeneration air carrying moisture can be discharged from the exhaust port 27 of the regeneration channel 2. A fan 9 can also be installed in the regeneration channel 2 to provide power for the airflow within it. Optionally, a heating structure can be installed in the regeneration channel 2 to heat the regeneration air, thereby increasing its temperature and improving the regeneration effect on the first regeneration zone 312.

[0118] The regeneration channel 2 includes multiple primary regeneration pipelines 21. Each primary regeneration pipeline 21 passes through a first regeneration treatment zone 3121. During the regeneration treatment of the first regeneration zone 3121, as the primary dehumidifying rotor 31 rotates, each first regeneration treatment zone 3121 sequentially passes through each primary regeneration pipeline 21, undergoing dehydration and regeneration treatment by the regeneration air from different primary regeneration pipelines 21. This allows the first regeneration zone 312 to be dehumidified multiple times, thereby improving the dehydration and regeneration effect. Simultaneously, the regeneration air temperature in each primary regeneration pipeline is different, meaning that only a portion of the regeneration air in the primary regeneration pipelines can be heated to a high temperature. This eliminates the need for all areas of the entire regeneration zone to use high-temperature regeneration air for drying and regeneration, thus reducing energy consumption during the dehumidifying rotor regeneration process.

[0119] According to some embodiments of this application, the regeneration air temperature of the multiple primary regeneration pipelines 21 is set to decrease along the rotation direction of the primary dehumidification impeller 31.

[0120] In this embodiment, the regeneration air temperature in each primary regeneration pipe 21 of the regeneration channel 2 is different. Along the rotation direction of the primary dehumidification rotor 31, the temperature of the regeneration air provided by the upstream primary regeneration pipe 21 is higher than the temperature of the regeneration air provided by the downstream primary regeneration pipe 21. With this arrangement, when regenerating the first regeneration zone 312, as the primary dehumidification rotor 31 rotates, the first regeneration processing zone 3121 in the first regeneration zone 312 first rotates to correspond to the primary regeneration pipe 21 with a higher airflow temperature, so that most of the moisture is removed by the higher-temperature airflow. Then, the first regeneration processing zone 3121 rotates to correspond to the primary regeneration pipe 21 with a relatively lower airflow temperature for dehumidification again, so that the remaining moisture is removed by the airflow. With this arrangement, the first regeneration zone 312 only needs to be locally heated to a high temperature, reducing the energy consumption during the regeneration of the first regeneration zone 312. Furthermore, since the airflow temperature is lower downstream of the rotation direction, the temperature of the regenerated impeller is also relatively lower. When the regenerated impeller rotates to the first moisture absorption zone 311, the temperature difference between it and the airflow in the dehumidification channel 1 will also decrease, thereby reducing the heat and cold offset between the first moisture absorption zone 311 and the airflow and reducing energy waste.

[0121] Optionally, to differentiate the regeneration air temperature in the primary regeneration pipelines 21, heating structures can be installed on each primary regeneration pipeline 21. These heating structures heat the airflow in each primary regeneration pipeline 21, raising the regeneration air temperature to the desired level. Specifically, the heating efficiency of the heating structure in the upstream primary regeneration pipeline 21 can be higher than that of the heating structure in the downstream primary regeneration pipeline 21. Furthermore, in some embodiments, the regeneration channel 2 can be configured to include a mixing duct 22 and multiple primary regeneration pipelines 21, with regeneration air flowing from the mixing duct 22 to each primary regeneration pipeline 21. A first heating structure 201 is installed on the mixing duct 22 to heat the regeneration air, and heating structures are installed on each of the multiple primary regeneration pipelines 21, heating the regeneration air to the desired temperature through these heating structures. In some embodiments, when a mixing air passage and a first heating structure 201 located in the mixing air passage are provided, the downstream primary regeneration pipeline 21 may not need to be equipped with a heating structure, and the airflow can be heated to the required temperature by the first heating structure 201 in the mixing air pipeline 22.

[0122] Optionally, the first regeneration zone 312 includes two first regeneration processing zones 3121. The central angle of the upstream first regeneration processing zone 3121 can be set to 60° to 75°, and the central angle of the downstream first regeneration processing zone 3121 can be set to 15° to 30°.

[0123] Referring to Figure 8, according to some embodiments of this application, the primary dehumidifying impeller 31 has a first surface and a second surface disposed opposite to each other along its axial direction. The mesopores 316 of the primary dehumidifying impeller 31 are reduced in size along the direction from the first surface to the second surface. The air inlet end of the first moisture absorption zone 311 is located on the first surface, and the air inlet end of the first regeneration zone 312 is located on the second surface.

[0124] The mesopores 316 in the dehumidifying rotor refer to the pore structure present in the adsorbent of the rotor. The presence of mesopores 316 can increase the large surface area for sufficient contact between humid air and the moisture-absorbing medium, which is beneficial to improving dehumidification efficiency; it can also increase the adsorption capacity of the adsorbent, providing additional adsorption space, allowing the adsorbent to adsorb more moisture and improve the moisture absorption capacity of the dehumidifying rotor.

[0125] In this embodiment, the direction from the first surface of the primary dehumidifying impeller 31 to the second surface is the moisture absorption direction of the primary dehumidifying impeller 31. The dehumidifying airflow enters the first moisture absorption zone 311 from the first surface, and the moisture in the airflow is absorbed by the primary dehumidifying impeller 31. The dehumidified airflow flows out from the second surface and enters the downstream of the dehumidification channel 1. The direction from the second surface to the first surface is the dehydration direction of the primary dehumidifying impeller 31. The regeneration air flows into the first regeneration zone 312 from the second surface, carrying away the moisture absorbed in the first regeneration zone 312, and then flows out from the first surface.

[0126] Using the aforementioned rotor structure, during airflow dehumidification, the airflow first passes through the layer with larger pore sizes of mesopores 316 near the first surface. Due to the larger pore size of the mesopores 316, the specific surface area is increased, allowing more moisture in the airflow to be adsorbed in the layer near the first surface. As the airflow gradually flows towards the second surface, it flows into the layer with smaller pore sizes of the mesopores 316. Smaller water molecules in the airflow can also be adsorbed by the first-stage dehumidification rotor 31, improving the moisture absorption effect. During the regeneration process in the first regeneration zone 312, the regeneration air first contacts the layer with smaller pore sizes for heat exchange, allowing moisture in that layer to reach the surface area with larger pore sizes. Dehydration of the surface area is relatively easier, and even if the temperature of the regeneration air decreases after passing through the previous layer, it can still effectively remove moisture from the surface area, resulting in better dehydration and regeneration of the first regeneration zone 312.

[0127] Referring to Figure 8, according to some embodiments of this application, the primary dehumidification impeller 31 includes a first adsorption layer 314 and a second adsorption layer 315 stacked together. The mesopores 316 of the first adsorption layer 314 are larger than the mesopores 316 of the second adsorption layer 315, and the thickness of the first adsorption layer 314 is greater than the thickness of the second adsorption layer 315.

[0128] In this embodiment, the primary dehumidification rotor 31 is formed by stacking multiple adsorption layers. Taking a primary dehumidification rotor 31 having a first adsorption layer 314 and a second adsorption layer 315 as an example, the pore size of the mesopores 316 in the first adsorption layer 314 is larger than that in the second adsorption layer 315. The primary dehumidification rotor 31 is formed by stacking layers, which makes the preparation of the primary dehumidification rotor 31 more convenient and reduces the preparation difficulty. Furthermore, the thickness of the adsorption layer with smaller mesopores 316 and greater difficulty in dehydration is set to be relatively thin, which reduces the regeneration difficulty of the primary dehumidification rotor 31 and helps to reduce the regeneration energy consumption of the primary dehumidification rotor 31.

[0129] Referring to Figure 2, according to some embodiments of this application, the dehumidification module 3 further includes a secondary dehumidification impeller 33, which has a second moisture absorption zone 331 and a second regeneration zone 332 arranged circumferentially thereon; along the flow direction of the airflow in the dehumidification channel 1, the second moisture absorption zone 331 is located downstream of the first moisture absorption zone 311.

[0130] In this embodiment, when fresh air is introduced into the dehumidification channel 1 for dehumidification, the airflow in the dehumidification channel 1 passes through the first moisture absorption zone 311 of the first-stage dehumidification rotor 31, where the dehumidifying medium absorbs some of the moisture from the airflow. The airflow then flows to the second moisture absorption zone 331 of the second-stage dehumidification rotor 33, where the dehumidifying medium further absorbs at least some of the remaining moisture from the airflow, thus dehumidifying it again. By using two dehumidification rotors, the airflow undergoes multiple dehumidification processes, improving the dehumidification effect. Optionally, other dehumidification rotors can be installed after the second-stage dehumidification rotor 33 along the airflow direction in the dehumidification channel 1; additionally, other dehumidification rotors can also be installed between the first-stage and second-stage dehumidification rotors 31 and 33.

[0131] Optionally, in this embodiment, the first regeneration zone 312 and the second regeneration zone 332 can be arranged in the same regeneration channel 2. For example, the first regeneration zone 312 can be located downstream of the second regeneration zone 332, so that the regeneration air passing through the second regeneration zone 332 is blown towards the first regeneration zone 312 to regenerate the first regeneration zone 312, which can improve the utilization rate of the regeneration air. In this embodiment, the first air inlet 23 in the regeneration channel 2 used to connect the indoor air duct 4 can be located upstream of the second regeneration zone 332, or the first air inlet 23 can be located between the first regeneration zone 312 and the second regeneration zone 332; at this time, the regeneration channel 2 also has a third air inlet 25 located upstream of the second regeneration zone 332. The third air inlet 25 can be used to introduce at least one of indoor air, outdoor fresh air, and the treated air in the dehumidification duct 1.

[0132] When the first regeneration zone 312 and the second regeneration zone 332 are set in the same regeneration channel 2, the second regeneration zone 332 can also be located downstream of the first regeneration zone 312, so that the regeneration air passing through the first regeneration zone 312 is blown to the second regeneration zone 332 to regenerate the second regeneration zone 332, which can also improve the utilization rate of the regeneration air.

[0133] In some implementations, two regeneration channels 2 may be provided, with one regeneration channel 2 passing through the first regeneration zone 312 and the other regeneration channel 2 passing through the second regeneration zone 332 to perform regeneration treatment on the second regeneration zone 332; the source of the regeneration air passing through the second regeneration zone 332 may be at least one of indoor air, outdoor fresh air and the treatment air in the dehumidification channel 1.

[0134] Referring to Figures 2, 4 and 9, the second regeneration zone 332 in the secondary dehumidification rotor 33 does not need to be partitioned, that is, the regeneration temperature is the same in all parts of the second regeneration zone 332, and the rotor dehumidification device 100 can have only one channel passing through the second regeneration zone 332.

[0135] Referring to Figures 5 and 10, according to some embodiments of this application, the second regeneration zone 332 includes a plurality of second regeneration processing zones 3321 arranged circumferentially along the secondary dehumidification rotor 33, and the regeneration channel 2 is provided with a plurality of secondary regeneration pipelines 26, each secondary regeneration pipeline 26 passing through a second regeneration processing zone 3321.

[0136] In this embodiment, the second regeneration zone 332 of the secondary dehumidification rotor 33 is provided with multiple second regeneration treatment zones 3321 along the circumference of the secondary dehumidification rotor 33. The corresponding regeneration channel 2 is provided with multiple secondary regeneration pipelines 26 corresponding to the multiple second regeneration treatment zones 3321 of the secondary dehumidification rotor 33. When the second regeneration zone 332 is regenerated, as the secondary dehumidification rotor 33 rotates, each second regeneration treatment zone 3321 passes through each secondary regeneration pipeline 26 in sequence, so as to be dehydrated and regenerated by the regeneration air of different secondary regeneration pipelines 26, so that the second regeneration zone 332 is dehumidified multiple times, thereby improving the dehydration and regeneration effect.

[0137] According to some embodiments of this application, the regeneration air temperature of the multi-channel secondary regeneration pipeline 26 is set to decrease along the rotation direction of the secondary dehumidification impeller 33.

[0138] In this embodiment, the regeneration air temperature in each of the secondary regeneration pipes 26 of the regeneration channel 2 is different. Along the rotation direction of the secondary dehumidification rotor 33, the temperature of the regeneration air provided through the upstream secondary regeneration pipe 26 is higher than the temperature of the regeneration air provided through the downstream secondary regeneration pipe 26. With this arrangement, when regenerating the second regeneration zone 332, as the secondary dehumidification rotor 33 rotates, the second regeneration processing zone 3321 in the second regeneration zone 332 first rotates to correspond to the secondary regeneration pipe 26 with a higher airflow temperature, so that most of the moisture is removed by the higher-temperature airflow. Then, the second regeneration processing zone 3321 rotates to correspond to the secondary regeneration pipe 26 with a relatively lower airflow temperature for dehumidification again, so that the remaining moisture is removed by the airflow. With this arrangement, the second regeneration zone 332 only needs to be locally heated to a high temperature, reducing the energy consumption during the regeneration of the second regeneration zone 332. Furthermore, since the airflow temperature is lower downstream of the rotation direction, the temperature of the regenerated impeller is also relatively lower. When the regenerated impeller rotates to the second moisture absorption zone 331, the temperature difference between it and the airflow in the dehumidification channel 1 will also decrease, thereby reducing the offsetting effect of the hot and cold airflow between the second moisture absorption zone 331 and the airflow and reducing energy waste.

[0139] Referring to Figures 6 and 10, according to some embodiments of this application, along the rotation direction of the primary dehumidification rotor 31, the first regeneration treatment zone 3121 adjacent to the first moisture absorption zone 311 is the first sub-zone 3121a; along the rotation direction of the secondary dehumidification rotor 33, the second regeneration treatment zone 3321 adjacent to the second moisture absorption zone 331 is the second sub-zone 3321a, and the area of ​​the first sub-zone 3121a does not exceed the area of ​​the second sub-zone 3321a.

[0140] In this embodiment, the first regeneration processing zone 3121 adjacent to the first moisture absorption zone 311 is designated as the first sub-zone 3121a. In the primary dehumidification rotor 31, the regeneration temperature of the first sub-zone 3121a is higher than that of other downstream first regeneration processing zones 3121. Similarly, the second regeneration processing zone 3321 adjacent to the second moisture absorption zone 331 is designated as the second sub-zone 3321a. In the secondary dehumidification rotor 33, the regeneration temperature of the second sub-zone 3321a is higher than that of other downstream second regeneration processing zones 3321.

[0141] In this embodiment, the area of ​​the first sub-region 3121a is smaller than the area of ​​the second sub-region 3321a. When the diameters of the primary dehumidification rotor 31 and the secondary dehumidification rotor 33 are the same, the central angle of the first sub-region 3121a is smaller than the central angle of the second sub-region 3321a. Alternatively, the diameter of the secondary dehumidification rotor 33 can be larger than the diameter of the primary dehumidification rotor 31. When the central angles of the first and second sub-regions 3121a are the same, the second sub-region 3321a can also be larger than the first sub-region 3121a, meaning the high-temperature regeneration area of ​​the secondary dehumidification rotor 33 is larger than the high-temperature regeneration area in the primary dehumidification rotor 31. In this configuration, when the moisture absorption capacity of the secondary dehumidification rotor 33 is high or the aperture of the secondary dehumidification rotor 33 is relatively small, the dehydration difficulty of the secondary dehumidification rotor 33 is greater than that of the primary dehumidification rotor 31. By increasing the area of ​​the high-temperature dehumidification zone of the secondary dehumidification rotor 33, the secondary dehumidification rotor 33 can also have a better dehydration and regeneration effect. For the primary dehumidification rotor 31, which has a relatively lower dehydration difficulty, the area of ​​the high-temperature regeneration zone can be appropriately reduced to reduce the energy consumption during the regeneration of the first regeneration zone 312.

[0142] According to some embodiments of this application, the mesopores 316 in the secondary dehumidification rotor 33 are smaller than at least some of the mesopores 316 in the primary dehumidification rotor 31.

[0143] In this embodiment, at least some of the mesopores 316 in the primary dehumidification rotor 31 are larger than the mesopores 316 in the secondary dehumidification rotor 33. With this configuration, during the dehumidification process of the airflow passing through the primary dehumidification rotor 31 and the secondary dehumidification rotor 33 in sequence, the primary dehumidification rotor 31 can absorb most of the moisture in the airflow, and the secondary dehumidification rotor 33 with its small pores can further dehumidify the airflow. This prevents small water molecules in the airflow from flowing through the secondary dehumidification rotor 33, thus ensuring a better dehumidification effect.

[0144] According to some embodiments of this application, the diameter of the secondary dehumidification rotor 33 is larger than the diameter of the primary dehumidification rotor 31.

[0145] In this configuration, the secondary dehumidification rotor 33 has a large specific surface area, which can improve the moisture absorption capacity of the secondary dehumidification rotor 33, so as to ensure that the airflow has a good dehumidification effect after passing through the primary dehumidification rotor and the secondary dehumidification rotor in sequence.

[0146] According to some embodiments of this application, the thickness of the secondary dehumidification rotor 33 is less than the thickness of the primary dehumidification rotor 31.

[0147] This configuration reduces the thickness of the secondary dehumidification impeller 33, making it easier for the moisture adsorbed by the secondary dehumidification impeller 33 to be removed with the regeneration air, thus facilitating the dehydration and regeneration of the second regeneration zone 332.

[0148] Please refer to Figures 2, 4 and 5. According to some embodiments of this application, the second regeneration zone 332 is located upstream of the first regeneration zone 312 along the flow direction of the airflow in the regeneration channel 2.

[0149] In this embodiment, the first regeneration zone 312 and the second regeneration zone 332 are located in the same regeneration channel 2, and the second regeneration zone 332 is located upstream of the first regeneration zone 312. This allows the regeneration air passing through the second regeneration zone 332 to be blown towards the first regeneration zone 312 for regeneration, thereby improving the utilization rate of the regeneration air. Furthermore, the temperature of the regeneration air after regeneration in the second regeneration zone 332 is relatively high, which reduces the energy consumed to raise the temperature of the regeneration air when regenerating the first regeneration zone 312.

[0150] In addition, since the airflow has already been dehumidified by the first-stage dehumidification rotor 31, the moisture absorbed by the second-stage dehumidification rotor 33 is relatively small. The regenerated air will not be too humid after passing through the second regeneration zone 332. Compared with the method of letting the regenerated air pass through the first regeneration zone 312 and then flow to the second regeneration zone 332, the regeneration air has a poor regeneration effect on the second regeneration zone 332.

[0151] Referring to Figure 2, according to some embodiments of this application, the rotary dehumidifier 100 further includes a first processing air channel 5, the two ends of which are respectively connected to the dehumidification channel 1 and the regeneration channel 2; the connection position between the first processing air channel 5 and the regeneration channel 2 is located upstream of the first regeneration zone 312, so as to introduce part of the processing air in the dehumidification channel 1 into the regeneration channel 2.

[0152] In this embodiment, a portion of the processing air in the dehumidification channel 1 is introduced into the regeneration channel 2 as regeneration air, which can increase the air volume of the regeneration air and improve the utilization rate of the processing air.

[0153] The connection point between the first processing air duct 5 and the dehumidification duct 1 can be located upstream of the first moisture absorption zone 311. For example, a condensing module, a dehumidifying impeller, or other dehumidification structure can be installed upstream of the first moisture absorption zone 312. The first processing air duct 5 connects the dehumidification structure and the first moisture absorption zone 312, as shown in the first connection position 13 between the first condensing module 32 and the first moisture absorption zone 312 in the following embodiment. Of course, if no other dehumidification structure is installed upstream of the first moisture absorption zone 311, it can also be connected upstream of the first moisture absorption zone 311. In this case, the airflow guided to the regeneration duct 2 through the first processing air duct 5 is fresh air. Alternatively, the connection point between the first processing air duct 5 and the dehumidification duct 1 can be located downstream of the first moisture absorption zone 311. The processed air humidity after being dehumidified by the first-stage dehumidification impeller 31 is low, which can play a better role in regeneration.

[0154] Referring to Figure 2, according to some embodiments of this application, the dehumidification channel 1 has a first connection position 13 located upstream of the first moisture absorption zone 311; the first processing air channel 5 is connected to the first connection position 13.

[0155] In this embodiment, the first processing air channel 5 can be used to guide the processing air upstream of the first moisture absorption zone 311 in the dehumidification channel 1 to the regeneration channel 2 for utilization, thereby improving the utilization rate of this portion of regenerated air. Optionally, the dehumidification module 3 also includes a first condensing module 32 located upstream of the primary dehumidification impeller 31. In this case, the first connection position 13 can be located between the first condensing module 32 and the first moisture absorption zone 311, guiding part of the airflow in the dehumidification channel 1 that has undergone preliminary condensation and dehumidification into the regeneration channel 2 for regeneration of the primary dehumidification impeller 31. The humidity of the airflow after condensation and dehumidification is reduced, which not only improves the utilization rate of the processing air but also achieves a better regeneration effect on the first regeneration zone 312.

[0156] Referring to Figures 2 and 6, in some embodiments, along the rotation direction of the primary dehumidification impeller 31, the primary dehumidification impeller 31 further includes a first cooling zone 313 located between the first regeneration zone 312 and the first moisture absorption zone 311, and the first processing air passage 5 passes through the first cooling zone 313.

[0157] In this embodiment, the primary dehumidification impeller 31 also includes a first cooling zone 313. It is understood that after the first regeneration zone 312 is regenerated using regenerated air, the temperature of the impeller located in the first regeneration zone 312 rises. At this time, the first regeneration zone 312 is first turned to the location of the first cooling zone 313 so that this part of the impeller is pre-cooled to avoid the temperature of this part of the impeller being too high after it turns to the first moisture absorption zone 311, which would affect the moisture absorption effect.

[0158] In this embodiment, the first processing air duct 5 passes through the first cooling zone 313. The airflow cooled by the first condensation module 32 absorbs the heat of the first cooling zone 313, which can raise the temperature of the airflow in the first processing air duct 5, thereby reducing the energy consumed to raise the temperature of the regenerated air. In addition, it can accelerate the cooling efficiency of the first cooling zone 313, reduce the temperature difference between the airflow directly flowing to the first moisture absorption zone 311 and the first moisture absorption zone 311, thereby reducing the heat loss due to cold and heat and reducing energy waste.

[0159] Please refer to Figure 2. According to some embodiments of this application, the first processing air duct 5 includes a first branch pipe 51, a second branch pipe 52, and a third branch pipe 53. The first branch pipe 51 is connected to the first connection position 13 and passes through the first cooling zone 313. The second branch pipe 52 is connected to the air outlet end and the second air inlet position 24 of the first branch pipe 51. The third branch pipe 53 is connected to the air outlet end of the first branch pipe 51 and the second connection position 14 of the dehumidification duct 1. The second connection position 14 is located downstream of the first moisture absorption zone 311. The rotary dehumidifier 100 also includes a diversion control structure 54 disposed in the first processing air duct 5. The diversion control structure 54 is used to control the conduction state of the second branch pipe 52 and the third branch pipe 53.

[0160] In this embodiment, the "conduction state" of the second branch pipe 52 refers to the open / closed state and opening degree of the second branch pipe 52, and the "conduction state" of the third branch pipe 53 refers to the open / closed state and opening degree of the third branch pipe 53. For example, the second branch pipe 52 and the third branch pipe 53 can be controlled to be closed simultaneously, in which case the processing air of the dehumidification channel 1 will not be drawn out by the first processing air channel 5. Alternatively, one of the second branch pipe 52 and the third branch pipe 53 can be controlled to be open while the other is closed, so that the airflow of the first branch pipe 51 flows into the open branch pipe. In addition, the opening degree of the second branch pipe 52 and the third branch pipe 53 can be controlled to distribute the airflow to the second branch pipe 52 and the third branch pipe 53.

[0161] The diversion control structure 54 may include a control valve installed in the second branch pipe 52 and a control valve installed in the third branch pipe 53, which controls the conduction state of the corresponding branch pipe. The diversion control structure 54 may also be configured as a three-way valve, with the air inlet of the three-way valve connected to the air outlet of the first branch pipe 51, and the two air outlets of the three-way valve connected to the second branch pipe 52 and the third branch pipe 53 respectively. The conduction state of the second branch pipe 52 and the third branch pipe 53 is controlled by controlling the opening and closing state and opening degree of the two air outlets of the three-way valve.

[0162] Part of the treated air, which has been condensed by the first condensation module 32, is discharged from the dehumidification channel 1 through the first branch pipe 51. The flow direction of the treated air is controlled by the diversion control structure 54. The airflow can be controlled to flow through the second branch pipe 52 to the regeneration channel 2 for rotary regeneration, or the airflow can be controlled to flow through the third branch pipe 53 to the downstream of the first moisture absorption zone 311 and be directly discharged into the room or further dehumidified by other dehumidification structures, so as to be suitable for different working conditions and improve the flexibility and applicability of the rotary dehumidification equipment 100.

[0163] In practical applications, when it is not necessary to use the processing air after it has been processed by the first condensation module 32, the second branch pipe 52 and the third branch pipe 53 are closed at the same time. At this time, the processing air of the dehumidification channel 1 will not be drawn out by the first processing air channel 5.

[0164] When only the processing air is needed to cool the first cooling zone 313, the second branch pipe 52 is closed and the third branch pipe 53 is opened. This portion of the processing air flows through the first cooling zone 313 and then returns to the dehumidification channel 1 via the third branch pipe 53. When the processing air is needed to cool the first cooling zone 313 and also to regenerate the first regeneration zone 312, the second branch pipe 52 is opened. The processing air flowing through the first cooling zone 313 flows through the second branch pipe 52 to the first regeneration zone 312. At this time, the third branch pipe 53 can be closed or opened.

[0165] In some embodiments, the opening method can be selected based on the humidity of the processed air. For example, if other dehumidification structures, such as a condenser module or a dehumidification impeller, are provided downstream of the first moisture absorption zone 311, and the humidity of the outdoor fresh air is high, and the humidity of the processed air is still high after condensation by the first condenser module 32, the processed air is not suitable for regeneration. In this case, the second branch pipe 52 can be closed and the third branch pipe 53 can be opened, allowing the processed air in the first branch pipe 51 to flow into the third branch pipe 53 and into the downstream of the first moisture absorption zone 311 for further dehumidification by subsequent dehumidification structures. If the processed air is relatively dry after condensation by the first condenser module 32, the second branch pipe 52 can be opened, allowing the processed air to flow into the second branch pipe 52 for regeneration in the first regeneration zone 312. In this case, the third branch pipe 53 can be closed or opened.

[0166] Please refer to Figures 2 to 5. According to some embodiments of this application, the first condensing module 32 includes a plurality of surface coolers arranged sequentially along the airflow direction, and the cooling temperatures of the plurality of surface coolers are set in decreasing order.

[0167] In this embodiment, the first condensation module 32 includes a surface cooler with a coolant flow channel. By introducing a low-temperature coolant at the required temperature into the coolant flow channel, the area of ​​the surface cooler in contact with the airflow maintains the required cooling temperature. When the airflow passes through the surface cooler, it exchanges heat with the cooler, thus cooling the airflow and causing water in the airflow to condense, thereby achieving the purpose of cooling and dehumidifying the fresh air in the dehumidification channel 1. Optionally, the surface cooler can be provided with multiple fins arranged side by side, allowing airflow to flow between adjacent fins for heat exchange. The fins can be straight fins, corrugated fins, fin structures with protrusions 3223 as described in the following embodiment, or other shapes, and are not limited here.

[0168] Please refer to Figures 2 to 5. In some embodiments, the dehumidification module 3 further includes a first condensation module 32 located upstream of the primary dehumidification impeller 31.

[0169] Specifically, a first condensing module 32 is installed between the fresh air inlet 11 and the primary dehumidification impeller 31. This allows the outdoor fresh air flowing towards the primary dehumidification impeller 31 to first pass through the first condensing module 32 for condensation and dehumidification, resulting in condensate formation and reduced temperature and humidity. This lowers the dehumidification pressure of the primary dehumidification impeller 31 and also reduces its moisture absorption, thereby reducing the energy consumption for regeneration. The first condensing module 32 includes a surface cooler, and the number of surface coolers in the first condensing module 32 can be set according to requirements, such as one, two, or more.

[0170] In this embodiment, the first condensation module 32 is equipped with two or more surface coolers. Multi-stage surface coolers are used for step-by-step condensation and dehumidification, so that the airflow is condensed and dehumidified multiple times before flowing to the first-stage dehumidification rotor 31, thereby improving the condensation and dehumidification efficiency.

[0171] Simultaneously, the cooling temperature of the upstream surface cooler is set higher than that of the downstream surface cooler. Specifically, taking the first condensing module 32, which includes a first surface cooler 321 and a second surface cooler 322 downstream of the first surface cooler 321, as an example, the cooling temperature of the first surface cooler 321 is a first temperature, and the cooling temperature of the second surface cooler 322 is a second temperature. The first temperature is higher than the second temperature. The fresh air entering the dehumidification channel 1 first passes through the first surface cooler 321 to be cooled to the first temperature; the airflow at the first temperature then passes through the second surface cooler 322 to be cooled to the second temperature. This arrangement, on the one hand, eliminates the need to set the cooling temperature of the first surface cooler 321 to a lower second temperature when the first condensing module 32 is needed to cool the fresh air to the second temperature, thus reducing cooling energy consumption. On the other hand, the cooling temperature of the first surface cooler 321 can be relatively high to avoid a large temperature difference between the first surface cooler 321 and the fresh air, which would result in a large amount of heat and cold cancellation. By reducing the heat and cold cancellation, energy waste can be reduced. Similarly, since the airflow has been cooled to the first temperature by the first surface cooler 321, the temperature difference between the airflow flowing to the second surface cooler 322 and the second surface cooler 322 can also be reduced, thereby improving the cooling efficiency of the second surface cooler 322 for the airflow and reducing energy waste.

[0172] Understandably, the first condensing module 32 can be equipped with three or more surface coolers. With the arrangement of this embodiment, the cooling temperature of the upstream surface cooler does not need to be set low. Each surface cooler has high cooling efficiency, less energy waste, and the cooling energy consumption can be effectively reduced.

[0173] Please refer to Figures 2 to 5. In some embodiments, the multiple surface coolers include a first surface cooler 321 and a second surface cooler 322 located downstream of the first surface cooler 321. The cooling temperature of the second surface cooler 322 is 3°C to 8°C.

[0174] In this embodiment, the cooling temperature of the second surface cooler 322 can be set to any value between 3°C, 4°C, 5°C, 5.5°C, 6°C, 7°C, 8°C, and 3°C to 8°C; this can be achieved by introducing a low-temperature coolant of the corresponding temperature into the coolant flow channel in the second surface cooler 322. The cooling temperature of the first surface cooler 321 can be higher than the cooling temperature of the second surface cooler 322. For example, when the cooling temperature of the second surface cooler 322 is 6°C, the cooling temperature of the first surface cooler 321 can be, but is not limited to, 7°C, 8°C, 9°C, 10°C, 11°C, 12°C, 12.5°C, 13°C, 14°C, 15°C, 16°C, and other values ​​higher than 6°C, which are not limited here.

[0175] In this configuration, the airflow passing through the first condensation module 32 is cooled to a lower temperature, resulting in better cooling and dehumidification effects. This helps reduce the dehumidification pressure of the first-stage dehumidification impeller 31. When the processing air is used to cool the first cooling zone 313 of the first-stage dehumidification impeller 31, it also achieves a good cooling effect. When the processing air is used as regeneration air to regenerate the first regeneration zone 312 of the first-stage dehumidification impeller 31, it also avoids excessive humidity in the regeneration air, thus ensuring the regeneration effect.

[0176] In some embodiments, the cooling temperature of the first surface cooler 321 is 10°C to 15°C.

[0177] In this embodiment, the cooling temperature of the first surface cooler 321 can be set to any value between 10°C, 11°C, 12°C, 12.5°C, 13°C, 14°C, 15°C, and 10°C to 15°C. This can be achieved by introducing a low-temperature coolant of the corresponding temperature into the coolant channel of the first surface cooler 321. This configuration avoids a large temperature difference between the first surface cooler 321 and the second surface cooler 322, thereby preventing a large temperature difference between the processed air after passing through the first surface cooler 321 and the second surface cooler 322. This ensures that the processed air can be cooled to the preset temperature in the second surface cooler 322, improving the cooling efficiency of the second surface cooler 322 for the airflow and reducing energy waste.

[0178] In one embodiment, the spacing between two adjacent fins in at least one surface cooler does not exceed 1.8 mm.

[0179] In this embodiment, the plurality of surface coolers in the first condensing module 32 are configured such that the spacing between two adjacent fins in at least one surface cooler is set to no more than 1.8 mm. The fin spacing of the surface cooler can take values ​​of 1.8 mm, 1.7 mm, 1.6 mm, 1.55 mm, 1.5 mm, 1.4 mm, and any value greater than 0 but not exceeding 1.8 mm. This configuration allows for a higher fin density in the surface cooler, increasing the total heat exchange area of ​​the surface cooler, thereby improving heat exchange efficiency and cooling efficiency, and ensuring effective cooling of the airflow.

[0180] In practical applications, the fin spacing of each surface cooler in the first condensing module 32 can be set to no more than 1.8 mm, or the fin spacing of some surface coolers can be set to no more than 1.8 mm, and the fin spacing of other surface coolers can be set to greater than 1.8 mm.

[0181] Taking the first condensing module 32, which includes a first surface cooler 321 and a second surface cooler 322 located downstream of the first surface cooler 321, as an example, the fin spacing of the second surface cooler 322 can be set to no more than 1.8 mm to ensure that the second surface cooler 322 has good heat exchange efficiency and cooling efficiency. The fin spacing of the first surface cooler 321 can be set to be greater than the fin spacing of the second surface cooler 322. The fin spacing of the first surface cooler 321 can be within the range of no more than 1.8 mm, or it can be greater than 1.8 mm, for example, it can be set to 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, and other values.

[0182] Alternatively, the fin spacing of the first surface cooler 321 can be the same as or smaller than the fin spacing of the second surface cooler 322. Or, in some embodiments, the fin spacing of the first surface cooler 321 can be set to no more than 1.8 mm, and the fin spacing of the second surface cooler 322 can be set to more than 1.8 mm; no specific limitation is made here.

[0183] In some embodiments, the plurality of surface coolers include a first surface cooler 321 and a second surface cooler 322 located downstream of the first surface cooler 321. The first surface cooler 321 has a plurality of first fins 3211 arranged side by side, and the second surface cooler 322 has a plurality of second fins 3221 arranged side by side. The spacing between two adjacent second fins 3221 is smaller than the spacing between two adjacent first fins 3211.

[0184] In this embodiment, the surface cooler in the first condensing module 32 has multiple fins arranged side by side, with an airflow channel formed between adjacent fins. When airflow passes through the airflow channel, it can exchange heat with the fins on both sides. Taking the first condensing module 32 as an example, which includes a first surface cooler 321 and a second surface cooler 322, the first surface cooler 321 includes multiple first fins 3211 arranged side by side, and the second surface cooler 322 includes multiple second fins 3221 arranged side by side. By setting the fin spacing of the second surface cooler 322 to a smaller value, the density of the second fins 3221 is increased, thereby increasing the total heat exchange area of ​​the second surface cooler 322. This improves heat exchange efficiency and cooling efficiency, ensuring that the airflow can be cooled to the required temperature after passing through the second surface cooler 322, thus guaranteeing the cooling effect on the airflow. The arrangement of making the fin spacing of adjacent first fins 3211 greater than the fin spacing of two adjacent second fins 3221 is intended to illustrate that the structure of the first surface cooler 321 does not need to be too complex. A surface cooler with relatively weaker cooling efficiency can be used as the upstream surface cooler to simplify the structure of the upstream surface cooler and reduce the cost of the rotary dehumidifier 100.

[0185] Referring to Figures 12 and 13, in one embodiment, at least one surface cooler fin includes a fin body 3222 and a plurality of protrusion structures 3223 that are disposed opposite to the fin body 3222.

[0186] In this embodiment, the fins of the surface cooler include a fin body 3222 as the main structure. The fin body 3222 can be considered as a straight fin structure or a corrugated fin structure. Multiple protrusions 3223 are provided on the surface of the fin body 3222, which helps to increase the fin surface area, increase the contact area with the airflow, and increase airflow turbulence, thereby improving heat exchange efficiency and cooling efficiency. The shape of the protrusions 3223 can be rectangular, cylindrical, hemispherical, or other regular or irregular shapes. One type of protrusion 3223 or different shapes of protrusions 3223 can be provided in the same surface cooler.

[0187] Optionally, in specific applications, the fins of each surface cooler of the first condensing module 32 can be configured as the fins with the protruding structure 3223 described above, or some surface coolers can have the protruding structure 3223 on their fins, while the fins of other surface coolers can be without the protruding structure 3223.

[0188] Taking the first condensing module 32, which includes a first surface cooler 321 and a second surface cooler 322 located downstream of the first surface cooler 321, as an example, the fins of the second surface cooler 322 can be configured to include a fin body 3222 and a protrusion structure 3223, while the fins of the first surface cooler 321 do not have a protrusion structure 3223. This ensures that the second surface cooler 322 has better heat exchange efficiency and cooling efficiency, so that the airflow can be cooled to the required temperature after passing through the second surface cooler 322, ensuring the cooling effect on the airflow. Furthermore, it is not necessary to make the structure of the first surface cooler 321 too complex, thereby simplifying the structure of the upstream surface cooler and reducing the cost of the rotary dehumidifier 100.

[0189] Of course, in some embodiments, the first surface cooler 321 may also be configured to include a fin body 3222 and a protrusion structure 3223. Alternatively, the first surface cooler 321 may also be configured to include a fin body 3222 and a protrusion structure 3223, so that the fins of the second surface cooler 322 do not have a protrusion structure 3223.

[0190] Referring to Figures 11 and 12, in one embodiment, the plurality of surface coolers include a first surface cooler 321 and a second surface cooler 322 located downstream of the first surface cooler 321. The first surface cooler 321 has a plurality of first fins 3211 arranged side by side, and the second surface cooler 322 has a plurality of second fins 3221 arranged side by side. The surface area of ​​the first fins 3211 is smaller than the surface area of ​​the second fins 3221.

[0191] In this embodiment, the surface area of ​​the second fin 3221 in the second surface cooler 322 is made large to ensure that the second surface cooler 322 has good heat exchange efficiency and cooling efficiency, so that the airflow can be cooled to the required temperature after passing through the second surface cooler 322, ensuring the cooling effect on the airflow; and there is no need to make the structure of the first surface cooler 321 too complicated, so as to simplify the structure of the upstream surface cooler and reduce the cost of the rotary dehumidifier 100.

[0192] Optionally, the surface area of ​​the first fin 3211 can be smaller than that of the second fin 3221 by making the length of the first fin 3211 smaller than that of the second fin 3221; or by setting the first fin 3211 as a straight fin and the second fin 3221 as a corrugated fin; or, when both the first fin 3211 and the second fin 3221 are set as corrugated fins, a protruding structure 3223 can be provided on the surface of the fin body 3222 of the second fin 3221.

[0193] Please refer to Figures 2, 4 and 5. According to some embodiments of this application, the dehumidification module 3 further includes a second condensation module 34 located between the first moisture absorption zone 311 and the second moisture absorption zone 331.

[0194] In this embodiment, the dehumidification module 3 further includes a second condensation module 34, which may include one, two or more surface coolers. The airflow from the first moisture absorption zone 311 is first cooled by the second condensation module 34, which can cause condensation to form in the airflow, thereby cooling and dehumidifying the airflow. This can improve the dehumidification effect, reduce the dehumidification pressure of the secondary dehumidification impeller 33, and reduce the moisture absorption of the secondary dehumidification impeller 33, thereby reducing the energy consumption for the regeneration of the secondary dehumidification impeller 33.

[0195] Optionally, the cooling temperature of the second condensing module 34 can be set to 10°C to 15°C. When the second condensing module 34 is equipped with multiple surface coolers, the cooling temperatures of each surface cooler can be the same or different. Optionally, the cooling temperatures of the multiple surface coolers can be set to decrease.

[0196] Please refer to Figures 2, 4 and 5. According to some embodiments of this application, the regeneration channel 2 has a first air inlet 23 located between the first regeneration zone 312 and the second regeneration zone 332, and a third air inlet 25 located upstream of the second regeneration zone 332.

[0197] In this embodiment, the first air inlet 23 can be used to introduce at least one of indoor air, outdoor fresh air, and processing air in the dehumidification channel 1, and the third air inlet 25 can be used to introduce at least one of indoor air, outdoor fresh air, and processing air in the dehumidification channel 1.

[0198] In some embodiments, the regenerated air flowing through the second regeneration zone 332 is used to regenerate the first regeneration zone 312. In this case, at least one of the indoor air with lower humidity and the processing air can be introduced from the first air inlet 23 to mix with the regenerated air flowing through the second regeneration zone 332, so as to reduce the humidity of the airflow flowing from the second regeneration zone 332 to the first regeneration zone 312, so that the airflow flowing to the first regeneration zone 312 can better remove the moisture in the first regeneration zone 312, thereby achieving a better drying and regeneration effect.

[0199] Please refer to Figures 2, 4 and 5. According to some embodiments of this application, the regeneration channel 2 further includes a mixing duct 22, and multiple primary regeneration ducts 211 are connected to the outlet end of the mixing duct 22.

[0200] In this embodiment, the regeneration air flowing into the first regeneration zone 312 in the regeneration channel 2 may include, in addition to indoor return air, the processing air in the dehumidification channel 1, outdoor fresh air, and at least one of the regeneration air flowing through the second regeneration zone 332. The mixing channel ensures that the various airflows are mixed evenly before being distributed to each primary regeneration pipeline 21, resulting in a uniform airflow distribution in each primary regeneration pipeline 21 and ensuring that each first regeneration processing zone 3121 has a good regeneration effect. Optionally, in some embodiments, an airflow regulating valve 541 may be provided to control the amount of air flowing into each regeneration channel 2 from the mixing channel.

[0201] Please refer to Figures 2, 4 and 5. According to some embodiments of this application, the rotary dehumidifier includes a first heating structure 201 disposed in the mixing duct 22.

[0202] This configuration utilizes the first heating structure 201 to heat the regeneration air in the mixing channel before distributing it to each primary regeneration pipeline 21. This increases the temperature of the regeneration air, improves the regeneration effect on the first regeneration zone 312, and reduces the number of heating structures required in the primary regeneration pipelines 21. The first heating structure 201 may include at least one of a hot water heating element and an electric heating element.

[0203] Referring to Figures 2 to 5, according to some embodiments of this application, the multi-channel primary regeneration pipeline 21 includes a first regeneration pipeline 211 and a second regeneration pipeline 212 arranged sequentially along the rotation direction of the primary dehumidification rotor 31; wherein, the rotor dehumidification device 100 further includes a second heating structure 202 disposed on the first regeneration pipeline 211, the second regeneration pipeline 212 is not provided with a heating structure, or the second regeneration pipeline 212 is provided with a third heating structure 203, the heating power of the third heating structure 203 is less than the heating power of the second heating structure 202.

[0204] This configuration, by incorporating a second heating structure 202 within the first regeneration pipeline 211 to raise the gas temperature within 211, allows for independent control of the gas flow temperature within 211, providing greater flexibility in temperature control. A third heating structure 203 with lower heating efficiency can be incorporated into the second regeneration pipeline 212 to control the gas flow temperature and raise the gas temperature within 212 from the first regeneration pipeline 211. This effectively allows for free control and adjustment of the heating power of both the first and second heating components according to actual needs, enhancing the flexibility of temperature regulation.

[0205] Referring to Figure 2, according to some embodiments of this application, the dehumidification module 3 includes a secondary dehumidification impeller 33, and the dehumidification channel 1 has a second connection position 14 located downstream of the second moisture absorption zone 331; the impeller dehumidification device 100 includes a second processing air channel 6 connecting the second connection position 14 and the regeneration channel 2, and the connection position of the second processing air channel 6 and the regeneration channel 2 is located upstream of the second regeneration zone 332 of the secondary dehumidification impeller 33.

[0206] In this embodiment, the regeneration air flowing to the second regeneration zone 332 for regeneration treatment originates from the treated air in the dehumidification channel 1 after dehumidification by the primary dehumidification rotor 31 and the secondary dehumidification rotor 33. Specifically, the rotor dehumidification device 100 is provided with a second treated air channel 6. The second treated air channel 6 can export the treated air that has undergone multi-stage dehumidification in the dehumidification channel 1 from the second connection position 14 located downstream of the second moisture absorption zone 331, and guide the treated air to the third air inlet position 25 of the regeneration channel 2 so that it flows into the regeneration channel 2. This allows the airflow to flow through the regeneration channel 2 to the second regeneration zone 332 for regeneration treatment, which can improve the utilization rate of the treated air in the dehumidification channel 1. The treated air that has undergone multi-stage dehumidification is also relatively dry, which can achieve a better regeneration treatment effect on the second regeneration zone 332.

[0207] Referring to Figure 2, according to some embodiments of this application, the dehumidification module 3 includes a secondary dehumidification impeller 33, and the dehumidification channel 1 also includes a third connection position 15 located between the first moisture absorption zone 311 and the second moisture absorption zone 331. The impeller dehumidification device 100 also includes a third processing air channel 7 connecting the third connection position 15 and the regeneration channel 2. The connection position between the third processing air channel 7 and the regeneration channel 2 is located upstream of the second regeneration zone 332 of the secondary dehumidification impeller 33.

[0208] In this embodiment, the regeneration air flowing to the second regeneration zone 332 for regeneration treatment originates from the treated air that has been dehumidified by the first-stage dehumidification impeller 31 in the dehumidification channel 1. The impeller dehumidification device 100 is equipped with a third treated air channel 7. This third treated air channel 7 can draw the treated air from the dehumidification channel 1 after dehumidification by the first-stage dehumidification impeller 31 from the third connection position 15 located between the first and second moisture absorption zones 311, and guide this treated air to the third air inlet 25 of the regeneration channel 2 so that it flows into the regeneration channel 2. This allows the airflow to flow through the regeneration channel 2 to the second regeneration zone 332 for regeneration treatment, improving the utilization rate of the treated air in the dehumidification channel 1. The treated air dehumidified by the first-stage dehumidification impeller 31 is also relatively dry, resulting in a better regeneration effect on the second regeneration zone 332.

[0209] Referring to Figures 4 and 9, according to some embodiments of this application, along the rotation direction of the secondary dehumidification impeller 33, the secondary dehumidification impeller 33 further includes a second cooling zone 333 located between the second regeneration zone 332 and the second moisture absorption zone 331, and the third processing air duct 7 passes through the second cooling zone 333.

[0210] In this embodiment, the processing air exiting through the third processing air duct 7 first flows to the second cooling zone 333 of the secondary dehumidification rotor 33. This part of the airflow absorbs the heat of the second cooling zone 333, which can both raise the temperature of the airflow flowing to the third air inlet 25, thereby reducing the energy consumed to raise the temperature of the regenerated air; and also accelerate the cooling efficiency of the second cooling zone 333, reduce the temperature difference between the airflow flowing to the second moisture absorption zone 331 and the second moisture absorption zone 331, thereby reducing the heat and cold offset and reducing energy waste.

[0211] Optionally, in some embodiments, the indoor air duct 4 has a second return air duct 42 communicating with the third air inlet 25; an air guide pipe can be provided communicating with the third processing air duct 7 and the second return air duct 42, and the air guide pipe is connected to the third air inlet 25 so that the airflow in the second return air duct 42 mixes with the airflow in the third processing air duct 7 before flowing to the third air inlet 25. In this case, the air guide pipe can pass through the second cooling zone 333, thus eliminating the need for the third processing air duct 7 and the second return air duct 42 to pass through the second cooling zone 333 separately, simplifying the structural design. Alternatively, the third processing air duct 7 and the second return air duct 42 can each pass through the second cooling zone 333 before connecting to the air guide pipe.

[0212] Referring to Figure 2, according to some embodiments of this application, the rotary dehumidifier 100 further includes an indoor air duct 4, which is connected to the regeneration duct 2; the connection between the indoor air duct 4 and the regeneration duct 2 is located upstream of the first regeneration zone 312.

[0213] In this embodiment, relatively dry indoor air is used as regenerated air to dry and regenerate the first regeneration zone of the primary dehumidification rotor 31. This portion of indoor air can be discharged outdoors through the exhaust port 27 of the regeneration channel 2. That is, the rotor dehumidification device 100 can be used to introduce fresh air and exhaust indoor air to balance indoor air pressure and humidity, keeping indoor air pressure and humidity stable. No other indoor air exhaust system is required, making it convenient to use. Furthermore, the low-humidity indoor return air can be reused. The indoor air has a certain temperature, which reduces the energy consumed to raise the temperature of the regenerated air.

[0214] Referring to Figure 2, in some embodiments, the dehumidification module 3 includes a two-stage dehumidification impeller 33, the regeneration channel 2 has a first air inlet 23 located upstream of the first regeneration zone 312 and a third air inlet 25 located upstream of the third regeneration zone 332, and the indoor air duct 4 includes a first return air duct 41 and a second return air duct 42, the first return air duct 41 being connected to the first air inlet 23 and the second return air duct 42 being connected to the third air inlet 25.

[0215] In this embodiment, the regenerated air flowing to the second regeneration zone 332 for regeneration processing originates from indoor air. The indoor air duct 4 is provided with a first return air duct 41 for connecting to the first air inlet 23 and a second return air duct 42 for connecting to the third air inlet 25. By guiding a portion of the indoor air to the first regeneration zone 312 for regeneration processing through the first return air duct 41 and guiding a portion of the indoor air to the second regeneration zone 332 for regeneration processing through the second return air duct 42, the utilization rate of indoor air can be improved.

[0216] Optionally, the first return air duct 41 and the second return air duct 42 can be independent of each other or connected to the same air inlet duct. A control structure can be set to control the airflow from the air inlet duct to the first return air duct 41 and the second return air duct 42. For example, regulating valves can be set in the first return air duct 41 and the second return air duct 42 respectively, or a three-way valve or other structure can be set at the connection position of the air inlet duct, the first return air duct 41 and the second return air duct 42. The airflow sent to the first air inlet position 23 and the second air inlet position 24 can be adjusted according to the dehydration and regeneration requirements of the first regeneration zone 312 and the second regeneration zone 332, so that both the first regeneration zone 312 and the second regeneration zone 332 have good regeneration effect and the indoor air is fully and efficiently utilized.

[0217] Referring to Figures 2 and 9, according to some embodiments of this application, along the rotation direction of the secondary dehumidification impeller 33, the secondary dehumidification impeller 33 further includes a second cooling zone 333 located between the second regeneration zone 332 and the second moisture absorption zone 331, and the second return air duct 42 passes through the second cooling zone 333.

[0218] In this embodiment, the secondary dehumidification rotor 33 also includes a second cooling zone 333. It is understood that after the second regeneration zone 332 is regenerated using regenerated air, the rotor temperature in the second regeneration zone 332 rises. At this time, the second regeneration zone 332 is first turned to the location of the second cooling zone 333 so that this part of the rotor is cooled down and pre-cooled to avoid the rotor temperature being too high after it turns to the second moisture absorption zone 331, which would affect the moisture absorption effect.

[0219] In this embodiment, the airflow in the second return air duct 42 absorbs the heat from the second cooling zone 333, which can both raise the temperature of the airflow in the second return air duct 42, thereby reducing the energy consumed to raise the temperature of the regenerated air; and also accelerate the cooling efficiency of the second cooling zone 333, reduce the temperature difference between the airflow flowing to the second moisture absorption zone 331 and the second moisture absorption zone 331, thereby reducing the heat-cold offsetting and reducing energy waste.

[0220] Please refer to Figures 2, 4 and 5. According to some embodiments of this application, the indoor air duct 4 includes two return air ducts, one of which is connected to the regeneration duct 2, and the other is connected to the dehumidification duct 1.

[0221] In this embodiment, the indoor air duct 4 includes at least two return air ducts. One return air duct is used to supply air to the regeneration duct 2, and the other return air duct is used to supply air to the dehumidification duct 1. The indoor air with lower humidity can be introduced into the dehumidification duct 1 and mixed with the airflow in the dehumidification duct 1. This can increase the airflow in the dehumidification duct 1 and also reduce the humidity of the airflow in the dehumidification duct 1 by using the indoor air.

[0222] For ease of explanation, the return air duct connected to the dehumidification duct 1 is referred to as the third return air duct 43. The third return air duct 43 can be connected upstream of the first moisture absorption zone 311 or downstream of the first moisture absorption zone 312.

[0223] In some embodiments, the dehumidification module 3 includes a two-stage dehumidification impeller 33, and the dehumidification channel 1 has a fourth connection position 16 located between the first moisture absorption zone 311 and the second moisture absorption zone 331; the third return air channel 43 can communicate with the fourth connection position 16. When the two-stage dehumidification impeller 33 is provided, the connection position between the indoor air channel 4 and the regeneration channel 2 can be located between the first regeneration zone 312 and the second regeneration zone 332, or it can be located upstream of the second regeneration zone 332, or a first return air channel 41 and a second return air channel 42 can be provided respectively, with the first return air channel 41 connected between the first regeneration zone 312 and the second regeneration zone 332, and the second return air channel 42 connected upstream of the second regeneration zone 332.

[0224] Referring to Figure 2, according to some embodiments of this application, the rotary dehumidifier 100 further includes a fresh air duct 8, which is connected to the regeneration duct 2. Along the flow direction of the airflow in the regeneration duct 2, the connection position between the fresh air duct 8 and the regeneration duct 2 is located upstream of the first regeneration zone 312.

[0225] In this embodiment, the rotary dehumidifier 100 is provided with a fresh air duct 8. The airflow source in the regeneration duct 2 also includes indoor return air introduced through the indoor air duct 4. Outdoor fresh air can be introduced to dry and regenerate the first regeneration zone 312 of the primary dehumidifier rotary wheel 31, thereby increasing the air volume of the regeneration air and improving the regeneration effect.

[0226] In some embodiments, the airflow source in the regeneration channel 2 may also include the processing air in the dehumidification channel 1. Since both the indoor return air and the processing air are relatively dry, even if outdoor fresh air is introduced into the regeneration channel 2 as regeneration air, the humidity of the regeneration air after mixing with the indoor return air and the processing air will be lower than the humidity of the outdoor fresh air. Therefore, even if outdoor fresh air is introduced as regeneration air, it will not cause excessive humidity in the regeneration air, thus affecting the regeneration treatment of the first regeneration zone 312. Alternatively, an airflow regulating valve 541 can be installed on the fresh air channel 8 to reduce the opening of the fresh air channel 8 or close the fresh air channel 8 when the humidity of the outdoor fresh air is high, thereby reducing or eliminating the introduction of fresh air and preventing excessive humidity in the regeneration air.

[0227] Please refer to Figure 2. According to some embodiments of this application, the rotary dehumidifier 100 also includes an airflow regulating valve 541 disposed in the fresh air duct 8. The airflow regulating valve 541 is used to control the conduction state of the fresh air duct 8.

[0228] In this embodiment, the conduction state of the fresh air duct 8 refers to its open / closed state and opening degree. The airflow regulating valve 541 controls the conduction state of the fresh air duct 8 to select whether to introduce outdoor fresh air or control the amount of outdoor fresh air introduced, improving operational flexibility. For example, when the outdoor fresh air humidity is low, the fresh air duct 8 is opened to introduce outdoor fresh air for regeneration treatment of the first regeneration zone 312. When the outdoor fresh air humidity is high, the opening degree of the fresh air duct 8 is reduced or the fresh air duct 8 is closed to reduce or eliminate the introduction of fresh air, avoiding excessive humidity in the regenerated air.

[0229] Please refer to Figures 2 to 5. According to some embodiments of this application, the dehumidification module 3 also includes a condensation module disposed in the dehumidification channel 1.

[0230] In this embodiment, the condensing module can be located upstream of the primary dehumidification impeller 31, such as the first condensing module 32 in the previous embodiment; the condensing module can also be located downstream of the primary dehumidification impeller 31, such as the third condensing module 35 located near the exhaust port 12; or, as in the previous embodiment, the second condensing module 34 located between the primary dehumidification impeller 31 and the secondary dehumidification impeller 33. The condensing module can be used to cool the airflow in the dehumidification channel and cause condensate to be released from the airflow, thereby improving the dehumidification capacity of the impeller dehumidification equipment.

[0231] The implementation methods of the first condensing module 32 and the second condensing module 34 are the same as those described in the previous embodiments and will not be repeated here. The third condensing module 35, which is located near the exhaust port 12, may include one, two, or more surface coolers; the third condensing module 35 can be used to further condense and dehumidify the airflow before it is discharged into the room from the dehumidification channel 1, thereby improving dehumidification efficiency, and can also control the temperature of the airflow discharged into the room. Of course, the third condensing module 35 may not be turned on when further dehumidification and temperature regulation are not required.

[0232] In some embodiments, the cooling temperature of the third condensing module 35 is set to 3°C to 8°C, and can be set to any value between 3°C, 4°C, 5°C, 5.5°C, 6°C, 7°C, 8°C, and 3°C to 8°C, so as to achieve a better cooling effect.

[0233] In some embodiments, a heating module can be provided upstream of the exhaust port 12 to heat the airflow when the temperature of the dehumidified airflow is low.

[0234] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
