Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification, in particular to a rotary dehumidification device. Background Art

[0002] In order to meet the production process requirements, the relative humidity of the workshops in multiple processes of the battery factory needs to be controlled to meet the environmental humidity control requirements. In related technologies, a rotary dehumidification device can be used to introduce outdoor fresh air and dehumidify the fresh air before discharging it into the room. The dehumidification wheel is used as the core dehumidification structure in the rotary dehumidification device. In order to ensure the dehumidification effect, multiple dehumidification wheels are currently used in the rotary dehumidification device for step dehumidification, resulting in a large size of the rotary dehumidification device and requiring a large installation space. Utility Model Content

[0003] The main purpose of the utility model is to provide a rotary dehumidification device, aiming to make the rotary dehumidification device have a better dehumidification effect and a smaller volume.

[0004] In order to achieve the above-mentioned purpose, the rotary dehumidification equipment proposed by the utility model comprises:

[0005] A dehumidification wheel, wherein the dehumidification wheel has a plurality of dehumidification zones and at least one regeneration zone arranged in a circumferential direction, wherein the plurality of dehumidification zones are arranged adjacent to each other;

[0006] a dehumidification passage, the dehumidification passage sequentially passing through the plurality of dehumidification zones; and

[0007] A regeneration channel passes through the regeneration zone.

[0008] According to the technical solution of the present application, a plurality of dehumidification zones are arranged on the dehumidification wheel, and a dehumidification channel for introducing fresh air for dehumidification passes through each dehumidification zone in sequence. With such arrangement, the airflow in the dehumidification channel can flow through each dehumidification zone in sequence for dehumidification treatment, thereby achieving a step dehumidification effect on a single dehumidification wheel, thereby achieving a better dehumidification effect, and there is no need to arrange a plurality of dehumidification wheels in the rotary dehumidification equipment, thereby reducing the volume of the rotary dehumidification equipment and reducing the installation space.

[0009] According to some embodiments of the present application, the plurality of dehumidification zones include a first dehumidification zone and a second dehumidification zone, and along the rotation direction of the dehumidification wheel, the first dehumidification zone is located downstream of the second dehumidification zone;

[0010] Along the flow direction of the airflow in the dehumidification channel, the first dehumidification zone is located upstream of the second dehumidification zone.

[0011] In this arrangement, the airflow in the dehumidification channel flows through the first dehumidification zone and the second dehumidification zone in sequence, and when the dehumidification wheel rotates, the hygroscopic material in the dehumidification wheel will first turn from the regeneration zone to the area where the second dehumidification zone is located and then to the area where the first dehumidification zone is located, that is, the second dehumidification zone is drier than the first dehumidification zone; at this time, the humidity of the airflow flowing through the first dehumidification zone is higher than the humidity of the airflow flowing through the second dehumidification zone, and the humidity of the airflow after flowing through the second dehumidification zone is lower, which has a better dehumidification effect. In addition, the second dehumidification zone used to process the airflow with lower humidity can also be rotated to the first dehumidification zone to be used for dehumidification of the airflow again, so that the dehumidification capacity of the hygroscopic material originally located in the second dehumidification zone can be fully utilized.

[0012] According to some embodiments of the present application, the dehumidification wheel has a first surface and a second surface arranged back to back, the air inlet end of the first dehumidification zone and the air outlet end of the second dehumidification zone are located on the first surface, and the air outlet end of the first dehumidification zone and the air inlet end of the second dehumidification zone are located on the second surface.

[0013] With this arrangement, the dehumidification channel can connect the air outlet of the first dehumidification zone and the air inlet of the second dehumidification zone on the same side of the dehumidification wheel (i.e., the second surface side), thereby simplifying the piping structure of the dehumidification channel, avoiding the piping structure of the dehumidification channel from being too tortuous, and making the piping arrangement of the dehumidification channel more convenient.

[0014] According to some embodiments of the present application, along the flow direction of the airflow in the dehumidification channel, the rotary dehumidification equipment also includes a first cooler arranged upstream of the plurality of dehumidification zones.

[0015] With this arrangement, the air flow introduced into the dehumidification channel can first be cooled by the first cooler to condense part of the water vapor in the air flow, thereby reducing the dew point and relative humidity of the air flow, improving the dehumidification capacity of the rotary dehumidification equipment, and also reducing the dehumidification pressure of the dehumidification wheel, which is beneficial to reducing the energy consumption for regenerating the dehumidification wheel.

[0016] According to some embodiments of the present application, along the airflow direction in the dehumidification channel, the rotary dehumidification equipment further includes a second cooler disposed between two adjacent dehumidification zones.

[0017] This arrangement can utilize the second cooler to cool the airflow, thereby reducing the dew point and relative humidity of the airflow, improving the dehumidification capacity of the rotary dehumidification equipment, and reducing the dehumidification pressure of the dehumidification zone downstream of the second cooler.

[0018] According to some embodiments of the present application, the rotary dehumidification device further includes a return air channel, the return air channel is communicated with the dehumidification channel, and the return air channel is used to receive indoor return air;

[0019] Along the flow direction of the airflow in the dehumidification channel, the communication position between the return air channel and the dehumidification channel is located upstream of at least one of the dehumidification zones.

[0020] This setting method introduces relatively dry indoor return air to mix with the air flow in the dehumidification channel. Since the dew point temperature of the indoor return air is relatively low, it can reduce the dew point and relative humidity of the air flow in the dehumidification channel, reduce the dehumidification pressure of the dehumidification wheel, and improve the dehumidification effect on the fresh air.

[0021] According to some embodiments of the present application, along the flow direction of the airflow in the dehumidification channel, the connecting position between the return air channel and the dehumidification channel is located between two adjacent dehumidification zones.

[0022] With this arrangement, the treated airflow introduced into the dehumidification channel first passes through at least one dehumidification zone for dehumidification treatment. The dry-bulb temperature of the treated airflow is increased to a certain extent, and its moisture content and relative humidity are reduced. At this time, the indoor return air is used to mix with this part of the airflow. Since the dew point temperature of the indoor return air is relatively low, the dew point and relative humidity of the treated airflow can be reduced, thereby reducing the dehumidification pressure of the downstream dehumidification zone and improving the dehumidification effect.

[0023] According to some embodiments of the present application, the rotary dehumidification equipment also includes a first filter arranged in the return air channel; this arrangement can filter out dust or other debris carried in the introduced indoor return air through the first filter, thereby preventing the debris from being contaminated in structures such as the dehumidification channel and the dehumidification wheel and affecting the dehumidification effect.

[0024] According to some embodiments of the present application, the rotary dehumidifier further comprises a return air regulating valve disposed in the return air passage. In this arrangement, the return air regulating valve can be used to control the opening and closing of the return air passage, and can also be used to adjust the opening of the return air passage to adjust the air volume of the indoor return air introduced into the return air passage.

[0025] According to some embodiments of the present application, the dehumidification wheel further includes a cooling zone, and along the rotation direction of the dehumidification wheel, the cooling zone is located between the regeneration zone and the dehumidification zone;

[0026] The rotary dehumidification device also includes a processing air channel passing through the cooling zone, and an air outlet end of the processing air channel is connected to an air inlet end of the regeneration channel.

[0027] With this arrangement, the regeneration air used to regenerate the regeneration zone first passes through the cooling zone of the dehumidification wheel to exchange heat with the cooling zone. It can take away the heat from the cooling zone to cool it down, and take away the heat from the cooling zone to avoid bringing heat into the dehumidification zone when the wheel in the cooling zone turns to the dehumidification zone. At the same time, the regeneration air will be preheated to a certain extent after passing through the relatively high-temperature cooling zone, so that the regeneration air is heated, and the energy consumption of heating the regeneration air can be used by the heater.

[0028] According to some embodiments of the present application, the air inlet end of the process air channel is connected to the dehumidification channel.

[0029] This arrangement, namely utilizing the airflow in the dehumidification channel as regeneration air, can improve the utilization rate of the airflow in the rotary dehumidification equipment.

[0030] According to some embodiments of the present application, along the flow direction of the airflow in the dehumidification channel, the connection position between the process air channel and the dehumidification channel is located downstream of at least one of the dehumidification zones.

[0031] With this arrangement, the airflow that has been dehumidified in at least one dehumidification zone is directed out of the dehumidification channel so that this part of the airflow flows to the treatment air channel as regeneration air. This part of the airflow has a lower humidity to ensure a better drying effect on the regeneration zone, allowing the dehumidification wheel to be better dehydrated and regenerated.

[0032] According to some embodiments of the present application, the dehumidification wheel includes a plurality of the regeneration zones, and the regeneration channel passes through the plurality of the regeneration zones in sequence.

[0033] This setting can reduce the drying area when the regeneration air passes through the dehumidification wheel once, making the regeneration air in the regeneration channel more concentrated, which is beneficial to increasing the wind speed and wind force of the regeneration air; and in the process of rotation of the dehumidification wheel, the dehumidification wheel can be dried by the regeneration air in different regeneration zones, which is beneficial to improving the drying effect and allowing the dehumidification wheel to be better dehydrated and regenerated.

[0034] According to some embodiments of the present application, the multiple regeneration zones include a first regeneration zone and a second regeneration zone. Along the rotation direction of the dehumidification wheel, the first regeneration zone is located downstream of the second regeneration zone; along the flow direction of the airflow in the regeneration channel, the first regeneration zone is located upstream of the second regeneration zone.

[0035] With this arrangement, the regeneration air for regenerating the first regeneration zone is relatively dry and has a higher temperature, thereby ensuring better drying of the first regeneration zone. The regeneration air is still relatively dry and high-temperature air after drying the first regeneration zone. This part of the airflow is used to dry the second regeneration zone with higher humidity, and can also take away most of the water vapor adsorbed by the second regeneration zone, so that the second regeneration zone can be better dehydrated. This is beneficial to saving the operating energy consumption of the regeneration process.

[0036] According to some embodiments of the present application, the dehumidification wheel has a first surface and a second surface arranged back to back, the air inlet end of the first regeneration zone and the air outlet end of the second regeneration zone are located on the first surface, and the air outlet end of the first regeneration zone and the air inlet end of the second regeneration zone are located on the second surface.

[0037] With this arrangement, the regeneration channel can connect the air outlet of the first regeneration zone and the air inlet of the second regeneration zone on the same side of the dehumidification wheel (i.e., the first surface side), thereby simplifying the piping structure of the regeneration channel, avoiding excessive tortuosity of the piping structure of the regeneration channel, and making the piping arrangement of the regeneration channel more convenient.

[0038] According to some embodiments of the present application, along the flow direction of the airflow in the regeneration channel, the rotary dehumidification equipment also includes a first heater arranged between two adjacent regeneration zones.

[0039] With this arrangement, the temperature of the regeneration air decreases after the regeneration air flows through the regeneration zone located upstream. At this time, the first heater can be used to heat the regeneration air to increase the temperature of the regeneration air so that the regeneration air can also have a better drying effect on the regeneration zone located downstream.

[0040] According to some embodiments of the present application, along the flow direction of the airflow in the regeneration channel, the rotary dehumidification equipment also includes a second heater arranged upstream of the regeneration zone.

[0041] With this arrangement, the second heater can be used to heat the regeneration air, thereby increasing the temperature of the regeneration air. The regeneration air with a higher temperature dries the regeneration zone, so that the regeneration zone can be dehydrated and regenerated better.

[0042] According to some embodiments of the present application, the rotary dehumidification equipment also includes a return air channel, which is connected to the regeneration channel; along the flow direction of the airflow in the regeneration channel, the connecting position between the return air channel and the regeneration channel is located upstream of the regeneration zone.

[0043] This setting uses indoor return air as regeneration air to dry and regenerate the regeneration area of ​​the dehumidification wheel, so that the indoor return air with low humidity can be reused; the indoor air has a certain temperature, which can reduce the energy consumed to increase the temperature of the regeneration air. And this part of the indoor air can be discharged to the outside from the dehumidification port of the regeneration channel, so that the use of the rotary dehumidification equipment can achieve the introduction of fresh air and exhaust of indoor air to balance the indoor air pressure and humidity, so that the indoor air pressure and humidity remain stable, without the need to set up other indoor air exhaust systems.

[0044] According to some embodiments of the present application, the rotary dehumidification equipment also includes a heat exchange module, which is located downstream of the multiple dehumidification zones along the airflow direction in the dehumidification channel, and the heat exchange module includes at least one of a third cooler and a third heater.

[0045] In this arrangement, the heat exchange module is used to adjust the temperature of the airflow after dehumidification so that the temperature of the airflow flowing into the room is appropriate. The third cooler and the third heater can be set up one by one, or the third cooler and the third heater can be set up at the same time and used one by one according to demand. The third cooler can be used to cool the airflow after dehumidification to avoid the airflow flowing into the room at a high temperature, and the third heater can be used to cool the airflow after dehumidification to avoid the airflow flowing into the room at a low temperature.

[0046] According to some embodiments of the present application, the dehumidification wheel comprises a wheel body and a plurality of baffles, the wheel body is provided with the dehumidification zone and the regeneration zone, and the wheel body can rotate relative to the baffles;

[0047] The barrier is arranged to extend in the radial direction of the dehumidification wheel and is located on the surface of the wheel body. The barrier is arranged at the edge positions of the dehumidification zone and the regeneration zone.

[0048] This arrangement utilizes a plurality of baffles to divide the dehumidification zones and regeneration zones on the rotor body. The baffles can be used to isolate the airflow between two adjacent zones to avoid cross-wind. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0066] In order to meet the production process requirements, the relative humidity of the workshops in multiple processes of the battery factory needs to be controlled to meet the environmental humidity control requirements. In the related technology, the rotary dehumidification device 100 can be used to introduce outdoor fresh air and dehumidify the fresh air before discharging it into the room. The rotary dehumidification device 100 uses a dehumidification wheel 1 as the core dehumidification structure. The dehumidification wheel 1 has the advantages of strong dehumidification capacity and large dehumidification capacity. The dehumidification wheel 1 is provided with a hygroscopic material as an adsorption medium. The dehumidification wheel 1 is divided into a dehumidification zone 111 and a regeneration zone 112. By rotating the dehumidification wheel 1, the adsorption medium of the dehumidification wheel 1 is circulated alternately in the dehumidification zone 111 and the regeneration zone 112.

[0067] During operation, the fresh air sucked in from the outside and the fresh air to be processed are dehumidified through the dehumidification area 111. The moisture in the fresh air is adsorbed by the dehumidification wheel 1 and becomes dry gas and then sent to the workshop. After absorbing moisture, the dehumidification wheel 1 rotates to the regeneration area 112 and is blown by a relatively high temperature dry airflow to dehydrate and regenerate the adsorption medium. In order to achieve low dew point air supply, the regeneration area 112 of the rotary dehumidifier needs to be blown by a high temperature dry airflow. The temperature of the high temperature dry airflow usually exceeds 120°C under some working conditions.

[0068] In order to ensure the dehumidification effect, currently, multiple dehumidification wheels 1 are used in the rotary dehumidification device 100 to perform step dehumidification, which results in the rotary dehumidification device 100 being larger in size and requiring a larger installation space.

[0069] Based on the above problems, the present invention proposes a rotary dehumidification device 100 .

[0070] Combined with reference Figure 1 and Figure 2 In one embodiment of the utility model, the rotary dehumidification device 100 includes a dehumidification wheel 1, a dehumidification channel 2 and a regeneration channel 3. The dehumidification wheel 1 has a plurality of dehumidification zones 111 and at least one regeneration zone 112 arranged along the circumferential direction, and the plurality of dehumidification zones 111 are adjacently arranged; the dehumidification channel 2 passes through the plurality of dehumidification zones 111 in sequence; and the regeneration channel 3 passes through the regeneration zone 112.

[0071] In the embodiment of the present application, the rotary dehumidification device 100 is provided with a dehumidification channel 2 for introducing outdoor fresh air. The dehumidification channel 2 can be formed by a structure such as an air pipe, or a shell or other structure can be provided in the rotary dehumidification device 100 to enclose the dehumidification channel 2. The dehumidification channel 2 is provided with a fresh air inlet for outdoor fresh air to enter, and an exhaust port for discharging the dehumidified airflow. In specific applications, the exhaust port is connected to the room to discharge the dehumidified airflow into the room; one or more fans 6 can be provided in the dehumidification channel 2 to generate suction force for extracting outdoor fresh air and power for the airflow to flow in the dehumidification channel 2. When the airflow flows along the dehumidification channel 2 and passes through the dehumidification wheel 1, the moisture in the airflow will be adsorbed by the adsorption medium in the dehumidification zone 111 of the dehumidification wheel 1, thereby achieving the effect of dehumidifying the airflow.

[0072] The dehumidification wheel 1 provided in the rotary dehumidification device 100 of the embodiment of the present application has a plurality of dehumidification zones 111 arranged in sequence along the rotation direction of the dehumidification wheel 1. The number of the dehumidification zones 111 may be, but is not limited to, two, three or more than three, and the plurality of dehumidification zones 111 are adjacent to each other. The dehumidification channel 2 for introducing fresh air passes through each dehumidification zone 111 in sequence; in this way, the airflow in the dehumidification channel 2 can flow through each dehumidification zone 111 in sequence for dehumidification treatment, and the effect of step dehumidification is achieved on a single dehumidification wheel 1, which can have a better dehumidification effect, and there is no need to provide a plurality of dehumidification wheels 1 in the rotary dehumidification device 100, which can reduce the volume of the rotary dehumidification device 100 and the installation space; and the plurality of dehumidification zones 111 are adjacent to each other, and when the dehumidification wheel 1 rotates, the hygroscopic medium in the dehumidification wheel 1 can play a hygroscopic role in each dehumidification zone 111 in sequence, and the dehumidification capacity of the hygroscopic material can be fully utilized, and then transferred to the regeneration zone 112 for regeneration treatment.

[0073] Optionally, taking the dehumidification wheel 1 having two dehumidification zones 111 as an example, the two dehumidification zones 111 are respectively the first dehumidification zone 111a and the second dehumidification zone 111b, and the dehumidification channel 2 passes through the first dehumidification zone 111a and the second dehumidification zone 111b in sequence, wherein, along the rotation direction of the dehumidification wheel 1, the first dehumidification zone 111a can be located upstream of the second dehumidification zone 111b, that is, the wheel structure turning from the regeneration zone 112 to the dehumidification zone 111 first passes through the first dehumidification zone 111a and then passes through the second dehumidification zone 111b. Alternatively, in the following embodiment, the second dehumidification zone 111b can be located upstream of the first dehumidification zone 111a, and the wheel structure turning from the regeneration zone 112 to the dehumidification zone 111 first passes through the second dehumidification zone 111b and then passes through the first dehumidification zone 111a.

Taking the setting of the first dehumidification zone 111a and the second dehumidification zone 111b as an example, the second dehumidification zone 111b can be set downstream of the first dehumidification zone 111a along the rotation direction, and after a period of dehumidification treatment, the first dehumidification zone 111a and the second dehumidification zone 111b are turned to the regeneration zone 112 for regeneration treatment. In addition, in the following embodiment, the second dehumidification zone 111b can be set upstream of the first dehumidification zone 111a, and after a period of dehumidification treatment, the wheel structure of the first dehumidification zone 111a is turned to the regeneration zone 112, and the wheel structure of the second dehumidification zone 111b is turned to the first dehumidification zone 111a. Of course, the dehumidification wheel 1 may also be in a state of continuous rotation during the dehumidification process, which is not limited here.

[0075] The regeneration channel 3 in the rotary dehumidification device 100 is used for the flow of regeneration wind. The regeneration channel 3 passes through the regeneration zone 112 of the dehumidification wheel 1, so that the regeneration wind dries the adsorption medium in the regeneration zone 112, so that the adsorption medium is dehydrated and regenerated; the regeneration wind carrying moisture after passing through the regeneration zone 112 can be discharged from the dehumidification port of the regeneration channel 3. A fan 6 can also be provided in the regeneration channel 3 to provide power for the airflow to flow in the regeneration channel 3. Optionally, a heating element can be provided in the regeneration channel 3 to heat the regeneration wind to increase the temperature of the regeneration wind and improve the drying effect on the regeneration zone 112. Optionally, the source of the airflow in the regeneration zone 112 can be but is not limited to at least one of indoor return air, outdoor fresh air and the treated air in the dehumidification channel 2, which is not limited here.

[0076] Optionally, a second filter 21 may be provided in the air inlet section of the dehumidification channel 2. The second filter 21 may filter out dust or other debris carried in the introduced fresh air, thereby preventing debris from accumulating in the dehumidification channel 2 and causing increased wind resistance, and preventing debris from adhering to the dehumidification wheel 1 and the cooler and other structures in the following embodiments and affecting the dehumidification effect; in addition, debris in the fresh air may be prevented from being introduced into the room. Optionally, one, two or more second filters 21 may be provided in the dehumidification channel 2, which is not limited here.

Optionally, an air supply regulating valve 26 may be provided at the exhaust port of the dehumidification channel 2, and the air supply regulating valve 26 may be used to control the opening and closing of the exhaust port; it may also be used to control the opening of the exhaust port to adjust the amount and speed of dry air sent into the room.

[0078] Optionally, a regeneration exhaust regulating valve 31 may be provided at the dehumidification port of the regeneration channel 3 to control the opening and closing of the dehumidification port; it may also be used to control the opening degree of the dehumidification port.

[0079] Combined with reference Figure 1 and Figure 2 According to some embodiments of the present application, the multiple dehumidification zones 111 include a first dehumidification zone 111a and a second dehumidification zone 111b. Along the rotation direction of the dehumidification wheel 1, the first dehumidification zone 111a is located downstream of the second dehumidification zone 111b; along the airflow direction in the dehumidification channel 2, the first dehumidification zone 111a is located upstream of the second dehumidification zone 111b.

[0080] In this embodiment, the airflow in the dehumidification channel 2 flows through the first dehumidification zone 111a and the second dehumidification zone 111b in sequence, and when the dehumidification wheel 1 rotates, the hygroscopic material in the dehumidification wheel 1 will first turn from the regeneration zone 112 to the area where the second dehumidification zone 111b is located and then to the area where the first dehumidification zone 111a is located, that is, the second dehumidification zone 111b is drier than the first dehumidification zone 111a; at this time, the humidity of the airflow flowing through the first dehumidification zone 111a is higher than the humidity of the airflow flowing through the second dehumidification zone 111b, and the humidity of the airflow after flowing through the second dehumidification zone 111b is lower, so as to ensure that the airflow discharged to the room is relatively dry. In addition, the second dehumidification zone 111b used to process the airflow with lower humidity can also be rotated to the first dehumidification zone 111a to be used for dehumidifying the airflow again, so that the dehumidification capacity of the hygroscopic material originally located in the second dehumidification zone 111b can be fully utilized. Optionally, in a specific application, the dehumidification wheel 1 can be kept in a state of continuous rotation, so that the first dehumidification zone 111a and the second dehumidification zone 111b always have a good dehumidification effect.

[0081] Combined with reference Figure 1 and Figure 2 According to some embodiments of the present application, the dehumidification wheel 1 has a first surface 114 and a second surface 115 that are arranged back to back, the air inlet end of the first dehumidification zone 111a and the air outlet end of the second dehumidification zone 111b are located on the first surface 114, and the air outlet end of the first dehumidification zone 111a and the air inlet end of the second dehumidification zone 111b are located on the second surface 115.

[0082] In this embodiment, the dehumidification channel 2 can be connected to the air outlet of the first dehumidification zone 111a and the air inlet of the second dehumidification zone 111b on the same side of the dehumidification wheel 1 (i.e., the second surface 115 side), simplifying the pipeline structure of the dehumidification channel 2, avoiding the pipeline structure of the dehumidification channel 2 being too tortuous, and making the pipeline arrangement of the dehumidification channel 2 more convenient. In specific applications, the airflow to be treated in the dehumidification channel 2 flows from the first surface 114 into the first dehumidification zone 111a to be dehumidified by the wheel structure of the first dehumidification zone 111a, and then the airflow flows out of the first dehumidification zone 111a from the second surface 115, and then returns to the second surface 115 to flow to the second dehumidification zone 111b, and the airflow after being dehumidified by the second dehumidification zone 111b flows out from the first surface 114.

[0083] See also Figure 1 According to some embodiments of the present application, along the airflow direction in the dehumidification channel 2, the rotary dehumidification device 100 also includes a first cooler 23 arranged upstream of the multiple dehumidification zones 111.

[0084] In this embodiment, the airflow introduced into the dehumidification channel 2 can first be cooled by the first cooler 23 to condense part of the water vapor in the airflow, thereby reducing the dew point and relative humidity of the airflow, improving the dehumidification capacity of the rotary dehumidification device 100, and also reducing the dehumidification pressure of the dehumidification wheel 1, thereby helping to reduce the energy consumption for regenerating the dehumidification wheel 1. Optionally, the number of the first coolers 23 can be one, two, or more than two.

[0085] Optionally, the first cooler 23 can be configured as a surface cooler, which is provided with a coolant flow channel. By introducing low-temperature coolant of the required temperature into the coolant flow channel, the area where the surface cooler contacts the airflow is maintained at the required cooling temperature. When the airflow passes through the surface cooler, the airflow exchanges heat with the surface cooler with a lower temperature, thereby cooling the airflow and allowing the water in the airflow to be analyzed to form condensed water, thereby achieving the effect of dehumidifying the airflow.

[0086] See also Figure 2 According to some embodiments of the present application, along the airflow direction in the dehumidification channel 2, the rotary dehumidification device 100 also includes a second cooler 24 arranged between two adjacent dehumidification zones 111.

[0087] In this embodiment, the second cooler 24 can be used to cool the airflow, reduce the dew point and relative humidity of the airflow, improve the dehumidification capacity of the rotary dehumidification device 100, and reduce the dehumidification pressure of the dehumidification zone 111 located downstream of the second cooler 24. Optionally, the second cooler 24 can also be set as a surface cooler. Optionally, the number of the second coolers 24 can be set to one, two, or more than two.

[0088] In some embodiments, along the flow direction of the airflow in the dehumidification channel 2, the rotary dehumidification equipment 100 includes a first cooler 23 arranged upstream of the multiple dehumidification zones 111 and a second cooler 24 arranged between two adjacent dehumidification zones 111, thereby better improving the dehumidification capacity of the rotary dehumidification equipment 100 and reducing the dehumidification pressure of the dehumidification wheel 1, which is beneficial to reducing the energy consumption for regenerating the dehumidification wheel 1.

[0089] See also Figure 2 According to some embodiments of the present application, the rotary dehumidification device 100 also includes a return air channel 4, which is connected to the dehumidification channel 2, and the return air channel 4 is used to receive indoor return air; along the flow direction of the airflow in the dehumidification channel 2, the connection position between the return air channel 4 and the dehumidification channel 2 is located upstream of at least one dehumidification zone 111.

[0090] In this embodiment, a return air channel 4 for introducing indoor return air is provided in the rotary dehumidification device 100. It should be noted that the indoor refers to the space into which the dry air flow after dehumidification by the rotary dehumidification device 100 is discharged. The indoor return air can be understood as a mixture of the dried air flow and the original indoor air. The humidity of the indoor return air is lower than the humidity of the outdoor fresh air introduced into the dehumidification channel 2.

[0091] The return air channel 4 is connected to the dehumidification channel 2. By introducing relatively dry indoor return air into the dehumidification channel 2 and mixing it with the airflow in the dehumidification channel 2, the dew point temperature of the indoor return air is relatively low, thereby reducing the dehumidification pressure of the dehumidification wheel 1 and improving the dehumidification effect on the fresh air. Optionally, along the flow direction of the airflow in the dehumidification channel 2, the connection position of the return air channel 4 and the dehumidification channel 2 can be located upstream of all dehumidification zones 111, or between two adjacent dehumidification zones 111, which is not limited here.

[0092] See also Figure 2 According to some embodiments of the present application, along the flow direction of the airflow in the dehumidification channel 2, the connecting position between the return air channel 4 and the dehumidification channel 2 is located between two adjacent dehumidification zones 111.

[0093] In this embodiment, the treated airflow introduced into the dehumidification channel 2 is first dehumidified by passing through at least one dehumidification zone 111. The dry-bulb temperature of the treated airflow is increased to a certain extent, and its moisture content and relative humidity are reduced. At this time, the indoor return air is used to mix with this part of the airflow. Since the dew point temperature of the indoor return air is relatively low, the dew point and relative humidity of the treated airflow can be reduced, thereby reducing the dehumidification pressure of the downstream dehumidification zone 111 and improving the dehumidification effect.

[0094] See also Figure 2According to some embodiments of the present application, the rotary dehumidification device 100 also includes a first filter 41 arranged in the return air duct 4; this arrangement can filter out dust or other debris carried in the introduced indoor return air through the first filter 41, thereby preventing the debris from being contaminated in structures such as the dehumidification duct 2 and the dehumidification wheel 1 and affecting the dehumidification effect.

[0095] See also Figure 2 According to some embodiments of the present application, the rotary dehumidification device 100 further includes a return air regulating valve 42 disposed in the return air channel 4. In this arrangement, the return air regulating valve 42 can be used to control the opening and closing of the return air channel 4, and can also be used to adjust the opening of the return air channel 4 to adjust the air volume of the indoor return air introduced into the return air channel 4.

[0096] See also Figure 1 According to some embodiments of the present application, the dehumidification wheel 1 also includes a cooling zone 113. Along the rotation direction of the dehumidification wheel 1, the cooling zone 113 is located between the regeneration zone 112 and the dehumidification zone 111; the rotary dehumidification equipment 100 also includes a treatment air channel 5 passing through the cooling zone 113, and the air outlet end of the treatment air channel 5 is connected to the air inlet end of the regeneration channel 3.

[0097] In the present embodiment, the dehumidification wheel 1 also includes a cooling zone 113. It can be understood that after the regeneration zone 112 is dried and regenerated by the regeneration wind, the temperature of the wheel structure located in the regeneration zone 112 rises. At this time, the wheel structure that completes the dehydration regeneration in the regeneration zone 112 is first turned to the cooling zone 113, so that this part of the wheel is subjected to a pre-cooling treatment to prevent the temperature of this part of the wheel from being too high after it is turned to the dehumidification zone 111, thereby affecting the dehumidification effect.

[0098] In this embodiment, the regeneration air used for regenerating the regeneration zone 112 first passes through the cooling zone 113 of the dehumidification wheel 1 to exchange heat with the cooling zone 113, which can take away the heat of the cooling zone 113 to cool down the cooling zone 113, and take away the heat of the cooling zone 113 to avoid bringing heat into the dehumidification zone 111 when the wheel located in the cooling zone 113 turns to the dehumidification zone 111. At the same time, the regeneration air will be preheated to a certain extent after passing through the relatively high temperature cooling zone 113, so that the regeneration air is heated, and the energy consumption of heating the regeneration air can be used by the heater.

[0099] See also Figure 2 According to some embodiments of the present application, the air inlet end of the processing air channel 5 is connected to the dehumidification channel 2.

[0100] In this embodiment, the air inlet end of the processing air channel 5 is connected to the dehumidification channel 2, that is, part of the airflow in the dehumidification channel 2 is used as regeneration air, and this part of the airflow is successively guided to the cooling zone 113 and the regeneration zone 112 through the processing air channel 5, thereby improving the utilization rate of the airflow in the rotary dehumidification equipment 100.

[0101] Optionally, along the flow direction of the air flow in the dehumidification channel 2, the connection position between the treatment air channel 5 and the dehumidification channel 2 can be located upstream of all dehumidification zones 111. For example, a first cooler 23 located upstream of all dehumidification zones 111 is arranged in the rotary dehumidification equipment 100, so that the connection position between the treatment air channel 5 and the dehumidification channel 2 can be located between the first cooler 23 and the dehumidification zone 111. The humidity and temperature of the air flow after condensation treatment by the first cooler 23 will also decrease, which can not only play a better cooling effect on the cooling zone 113, but also avoid high humidity in the regenerated air.

[0102] Of course, the connection position between the treatment air channel 5 and the dehumidification channel 2 can also be located between two adjacent dehumidification zones 111, or downstream of all dehumidification zones 111. The humidity of the air flow after dehumidification treatment by at least one dehumidification zone 111 will also decrease, which can avoid the high humidity of the air flow used as regeneration air and ensure the regeneration effect.

[0103] See also Figure 2 According to some embodiments of the present application, along the air flow direction in the dehumidification channel 2, the connection position between the treatment air channel 5 and the dehumidification channel 2 is located downstream of at least one dehumidification zone 111.

[0104] In this embodiment, the connection position between the processing air channel 5 and the dehumidification channel 2 is located between two adjacent dehumidification zones 111, or downstream of all dehumidification zones 111, and the air flow that has passed through at least one dehumidification zone 111 for dehumidification treatment is guided out from the dehumidification channel 2, so that this part of the air flow flows to the processing air channel 5 as regeneration air. The humidity of this part of the air flow is relatively low to ensure that the regeneration zone 112 can have a better drying effect, so that the dehumidification wheel 1 can be better dehydrated and regenerated.

[0105] See also Figure 2 According to some embodiments of the present application, the dehumidification wheel 1 includes a plurality of regeneration zones 112 , and the regeneration channel 3 passes through the plurality of regeneration zones 112 in sequence.

[0106] In this embodiment, the dehumidification wheel 1 is provided with a plurality of regeneration zones 112 arranged in sequence along the rotation direction of the dehumidification wheel 1. The number of the regeneration zones 112 may be, but is not limited to, two, three or more than three, and the plurality of regeneration zones 112 are adjacent to each other. The airflow in the regeneration channel 3 passes through the plurality of regeneration zones 112 in sequence to dry the wheel structure after moisture absorption. In this arrangement, the area of ​​the regeneration zone 112 dried by the regeneration wind in a single time is small, and the regeneration wind in the regeneration channel 3 is relatively concentrated, which is conducive to increasing the wind speed and wind force of the regeneration wind to improve the drying effect.

[0107] In some embodiments, taking the dehumidification wheel 1 as an example in which two regeneration zones 112 are provided, the two regeneration zones 112 are respectively the first regeneration zone 112a and the second regeneration zone 112b, and the regeneration channel 3 passes through the first regeneration zone 112a and the second regeneration zone 112b in sequence, wherein, along the rotation direction of the dehumidification wheel 1, the first regeneration zone 112a can be located upstream of the second regeneration zone 112b, that is, the wheel structure turning from the dehumidification zone 111 to the regeneration zone 112 first passes through the first regeneration zone 112a and then passes through the second regeneration zone 112b. Alternatively, in the following embodiment, the second regeneration zone 112b can be located upstream of the first regeneration zone 112a, and the wheel structure turning from the dehumidification zone 111 to the regeneration zone 112 first passes through the second regeneration zone 112b and then passes through the first regeneration zone 112a.

[0108] When the rotary dehumidification device 100 of this embodiment is used for dehumidification treatment, the dehumidification rotary wheel 1 can be stopped at first, and after a period of dehumidification treatment, all regeneration zones 112 or at least one regeneration zone 112 are turned to the dehumidification zone 111 or the cooling zone 113. Taking the first regeneration zone 112a and the second regeneration zone 112b as an example, the second regeneration zone 112b can be set downstream of the first regeneration zone 112a along the rotation direction, and after a period of dehumidification treatment, the first regeneration zone 112a and the second regeneration zone 112b are turned to the dehumidification zone 111 or the cooling zone 113 at the same time.

[0109] In addition, as in the following embodiment, the second regeneration zone 112b can be arranged upstream of the first regeneration zone 112a. After a period of dehumidification treatment, the rotor structure of the first regeneration zone 112a turns to the dehumidification zone 111 or the cooling zone 113, and the rotor structure of the second regeneration zone 112b turns to the first regeneration zone 112a. Of course, the dehumidification rotor 1 can also be in a state of continuous rotation during the dehumidification process, which is not limited here. It can be understood that the regeneration wind in the regeneration channel 3 is in a state of continuous flow, and the first regeneration zone 112a and the second regeneration zone 112b are in a state of being dried at the same time. After the partial structure of the second regeneration zone 112b is dehumidified by the regeneration wind, the partial structure moves to the first regeneration zone 112a with the rotation of the dehumidification rotor 1, and then is dried twice in the first regeneration zone 112a. That is, the dehumidification rotor 1 can be dried by the regeneration wind in different regeneration zones 112, which increases the number of times the rotor structure is dried, which is conducive to improving the drying effect, so that the dehumidification rotor 1 can be dehydrated and regenerated better.

[0110] Combined with reference Figure 1 and Figure 2According to some embodiments of the present application, the multiple regeneration zones 112 include a first regeneration zone 112a and a second regeneration zone 112b. Along the rotation direction of the dehumidification wheel 1, the first regeneration zone 112a is located downstream of the second regeneration zone 112b; along the flow direction of the airflow in the regeneration channel 3, the first regeneration zone 112a is located upstream of the second regeneration zone 112b.

[0111] In this embodiment, the regeneration wind in the regeneration channel 3 flows through the first regeneration zone 112a and the second regeneration zone 112b in sequence, and the humidity of the regeneration wind flowing through the first regeneration zone 112a is lower than the humidity of the regeneration wind flowing through the second regeneration zone 112b. When the dehumidification wheel 1 rotates, the hygroscopic material in the dehumidification wheel 1 will first reach the second regeneration zone 112b and then reach the first regeneration zone 112a after being rotated out of the dehumidification zone 111; it can be understood that the humidity of the hygroscopic material in the first regeneration zone 112a is lower than the humidity of the hygroscopic material in the second regeneration zone 112b. With such arrangement, the regeneration air for regenerating the first regeneration zone 112a is relatively dry and has a higher temperature, thereby ensuring that the first regeneration zone 112a is better dried; and the regeneration air is still relatively dry and high-temperature air after drying the first regeneration zone 112a. This part of the airflow is used to dry the second regeneration zone 112b with higher humidity, and can also take away most of the water vapor adsorbed by the second regeneration zone 112b, so that the second regeneration zone 112b can be better dehydrated, which is beneficial to saving the operating energy consumption of the regeneration process.

[0112] Combined with reference Figure 1 and Figure 2 According to some embodiments of the present application, the dehumidification wheel 1 has a first surface 114 and a second surface 115 which are arranged back to back, the air inlet end of the first regeneration zone 112a and the air outlet end of the second regeneration zone 112b are located on the first surface 114, and the air outlet end of the first regeneration zone 112a and the air inlet end of the second regeneration zone 112b are located on the second surface 115.

[0113] In this embodiment, the regeneration channel 3 can be connected to the air outlet of the first regeneration zone 112a and the air inlet of the second regeneration zone 112b on the same side of the dehumidification wheel 1 (i.e., the first surface 114 side), simplifying the pipeline structure of the regeneration channel 3, avoiding the pipeline structure of the regeneration channel 3 being too tortuous, and making the pipeline arrangement of the regeneration channel 3 more convenient. In specific applications, the regeneration wind in the regeneration channel 3 flows from the second surface 115 into the first regeneration zone 112a to dry the wheel structure located in the first regeneration zone 112a, and then the airflow flows out of the first regeneration zone 112a from the first surface 114, and then returns to the first surface 114 to flow to the second regeneration zone 112b to dry the second regeneration zone 112b.

[0114] See also Figure 2According to some embodiments of the present application, along the airflow direction in the regeneration channel 3 , the rotary dehumidification device 100 further includes a first heater 32 disposed between two adjacent regeneration zones 112 .

[0115] In this embodiment, after the regeneration wind flows through the regeneration zone 112 located upstream, the temperature of the regeneration wind decreases. At this time, the first heater 32 can be used to heat the regeneration wind to increase the temperature of the regeneration wind, so that the regeneration wind also has a good drying effect on the regeneration zone 112 located downstream. Optionally, the first heater 32 can be set to, but is not limited to, at least one of a hot water heating element and an electric heating element.

[0116] See also Figure 1 According to some embodiments of the present application, along the air flow direction in the regeneration channel 3, the rotary dehumidification equipment 100 also includes a second heater 33 arranged upstream of the regeneration zone 112.

[0117] In this embodiment, the second heater 33 can be used to heat the regeneration air, so that the regeneration air with a higher temperature after heating can dry the regeneration zone 112, so as to better dehydrate and regenerate the regeneration zone 112. Optionally, the second heater 33 can be set to, but not limited to, at least one of a hot water heating element and an electric heating element.

[0118] Combined with reference Figure 1 and Figure 2 According to some embodiments of the present application, the rotary dehumidification equipment 100 also includes a return air channel 4, which is connected to the regeneration channel 3; along the flow direction of the airflow in the regeneration channel 3, the connecting position between the return air channel 4 and the regeneration channel 3 is located upstream of the regeneration zone 112.

[0119] In this embodiment, the indoor return air is used as the regeneration air to dry and regenerate the regeneration area 112 of the dehumidification wheel 1, so that the indoor return air with low humidity can be reused; the indoor air has a certain temperature, which can reduce the energy consumed to increase the temperature of the regeneration air. And this part of the indoor air can be discharged to the outside from the dehumidification port of the regeneration channel 3, so that the use of the rotary dehumidification device 100 can achieve the introduction of fresh air and exhaust of indoor air to balance the indoor air pressure and humidity, so that the indoor air pressure and humidity remain stable, without the need to set up other indoor air exhaust systems.

[0120] Optionally, in some embodiments, the rotary dehumidification device 100 is provided with a processing air channel 5, and the two ends of the processing air channel 5 are respectively connected to the dehumidification channel 2 and the regeneration channel 3, so as to guide part of the airflow in the dehumidification channel 2 as the regeneration air; the return air channel 4 and the processing air channel 5 can be connected, so that the indoor return air is connected to the processing air channel 5, or the return air channel 4 is connected to the dehumidification channel 2, and the connection position of the return air channel 4 and the dehumidification channel 2 is located upstream of the connection position of the processing air channel 5 and the dehumidification channel 2. In this way, the indoor return air and the airflow in the dehumidification channel 2 can be mixed and then flow to the regeneration channel 3.

[0121] See also Figure 1 According to some embodiments of the present application, the rotary dehumidification equipment 100 also includes a heat exchange module 25. Along the airflow direction in the dehumidification channel 2, the heat exchange module 25 is located downstream of the multiple dehumidification zones 111. The heat exchange module 25 includes at least one of a third cooler 251 and a third heater 252.

[0122] In this arrangement, the heat exchange module 25 is used to adjust the temperature of the airflow after dehumidification so that the temperature of the airflow flowing into the room is appropriate. The third cooler 251 and the third heater 252 can be set up one by one, or the third cooler 251 and the third heater 252 can be set up at the same time and used one by one as needed. The third cooler 251 can be used to cool the airflow after dehumidification to avoid the airflow flowing into the room having a high temperature, and the third heater 252 can be used to cool the airflow after dehumidification to avoid the airflow flowing into the room having a low temperature.

[0123] Optionally, the third cooler 251 may also be configured as a surface cooler. Optionally, the number of the third coolers 251 may be one, two, or more than two.

[0124] Optionally, the third heater 252 may be configured as, but not limited to, at least one of a hot water heating element and an electric heating element.

[0125] See also Figure 1 and Figure 2 According to some embodiments of the present application, the dehumidification wheel 1 includes a wheel body 11 and a plurality of baffles 12. The wheel body 11 is provided with a dehumidification zone 111 and a regeneration zone 112. The wheel body 11 can rotate relative to the baffles 12.
