Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a rotary dehumidification device and an air conditioning system. Background Art

[0002] With the development of new energy, semiconductor, pharmaceutical and other industries, production equipment has become increasingly sophisticated, and the corresponding production plants have higher and higher requirements for air humidity in order to protect equipment and products, while also improving production efficiency. Therefore, rotary dehumidifiers are becoming more and more widely used.

[0003] The core component of the rotary dehumidifier is the dehumidification wheel. The surface of the dehumidification wheel is coated with a dehumidification medium. The dehumidification wheel is divided into a dehumidification treatment area and a regeneration area. Through slow rotation, the dehumidification wheel cycles alternately between the dehumidification treatment area and the regeneration area. At present, the rotary dehumidifier usually uses a heater to directly heat and heat the regeneration area for high-temperature drying and regeneration, which consumes a lot of energy and causes a waste of resources. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems in the background technology. To this end, one object of the present application is to provide a rotary dehumidification device and an air conditioning system to reduce the energy consumption of the rotary dehumidification device.

[0005] An embodiment of the first aspect of the present application provides a rotary dehumidification device, which includes a first air inlet channel, a first return air channel and a first dehumidification wheel, the first air inlet channel is used to receive outdoor fresh air; the first return air channel is used to receive indoor return air; the first dehumidification wheel includes a first treatment zone, a first regeneration zone and a second regeneration zone arranged in sequence along the rotation direction of the wheel; the inlet of the first treatment zone is connected to the first air inlet channel for adsorbing moisture in the fresh air; the first regeneration zone is connected to the first return air channel through a first regeneration pipeline, and the first regeneration pipeline is constructed to provide an airflow with a first temperature to the first regeneration zone; the second regeneration zone is connected to the first return air channel through a second regeneration pipeline, and the second regeneration pipeline is constructed to provide an airflow with a second temperature to the second regeneration zone; wherein the second temperature is greater than or equal to the first temperature.

[0006] In the technical solution of the embodiment of the present application, the original single regeneration zone is divided into a first regeneration zone and a second regeneration zone that can generate different temperatures. The first regeneration zone is preliminarily regenerated by using a first regeneration pipeline that can generate a first temperature to take away most of the moisture contained in the shallow surface of the first dehumidification wheel. Then, the second regeneration zone is deeply regenerated by using a second regeneration pipeline that can generate a higher temperature second temperature to take away a small amount of moisture contained in the deep holes of the first dehumidification wheel. The heating efficiency of the rotary dehumidification equipment is improved and the regeneration heating operation energy consumption of the rotary dehumidification equipment is reduced through the zoning and step temperature regeneration method. At the same time, the indoor return air is introduced through the first return air channel. The indoor return air is drier than the outdoor fresh air, and the temperature is higher than the treated fresh air temperature, which further effectively reduces the energy consumed in the first regeneration pipeline and the second regeneration pipeline to increase the gas temperature.

[0007] In some embodiments, a first heating component is provided upstream of the first regeneration zone in the first regeneration pipeline, and the first heating component is used to heat the airflow provided to the first regeneration pipeline to a first temperature; a second heating component is provided upstream of the second regeneration zone in the second regeneration pipeline, and the second heating component is used to heat the airflow provided to the second regeneration pipeline to a second temperature. By providing the first heating component in the first regeneration pipeline to increase the temperature of the gas in the first regeneration pipeline, and providing the second heating component in the second regeneration pipeline to increase the temperature of the gas in the second regeneration pipeline, the heating power of the first heating component and the second heating component can be freely controlled and adjusted according to actual needs, thereby improving the flexibility of temperature regulation.

[0008] In some embodiments, the heating efficiency of the first heating component is greater than the heating efficiency of the second heating component. By setting the heating efficiency of the first heating component to be greater than the heating efficiency of the second heating component, it is possible to simultaneously utilize low-grade heat sources with high energy efficiency ratios and high-grade heat sources with low energy efficiency ratios, and it is also possible to achieve cascade utilization of heat sources of different grades, thereby improving the energy efficiency ratio of the regeneration operation of the rotary dehumidification equipment.

[0009] In some embodiments, the first heating component includes a hot water heating element; and / or the second heating component includes a steam heating element or an electric heating element. The use of a hot water heating element can realize the use of a low-grade heat source with a high energy efficiency ratio, and reduce the regenerative heating operation energy consumption of the rotary dehumidification equipment; the use of a steam heating element or an electric heating element can make up for the temperature rise requirement that the first heating component does not meet, and reduce the regenerative heating operation energy consumption.

By setting the center angle of the first regeneration zone between 60° and 75°, and the center angle of the second regeneration zone between 15° and 30°, the dehumidification requirements can be met and the energy consumption can be reduced as much as possible.

[0011] In some embodiments, the rotary dehumidification device further includes a second dehumidification rotary wheel and a second air inlet channel, the second dehumidification rotary wheel includes a second processing zone, and the second air inlet channel is connected to the outlet of the first processing zone and the inlet of the second processing zone respectively. The dehumidification effect of the airflow can be further improved by adding a second dehumidification rotary wheel.

[0012] In some embodiments, the rotary dehumidification device further includes a second return air channel, which is configured to communicate with the second air inlet channel, and is used to mix the return air from the second return air channel and the fresh air processed in the first processing zone and provide the mixture to the second processing zone. The return air introduced into the room through the second return air channel can effectively utilize the return air in the room, and while balancing the indoor air pressure, the indoor return air with low humidity can be reused, reducing production waste. At the same time, the introduced return air increases the gas volume, which can correspondingly reduce the energy consumed by the introduction and drying of fresh air. The fresh air processed in the first processing zone is mixed with the return air from the second return air channel, which also improves the uniformity of the airflow in the second air inlet channel.

[0013] In some embodiments, the second dehumidification wheel also includes a third regeneration zone, which is connected to the second air inlet channel through a third regeneration pipeline, and the connection interface between the third regeneration pipeline and the second air inlet channel is located downstream of the connection interface between the second return air channel and the second air inlet channel. By connecting the third regeneration pipeline with the second air inlet channel, the third regeneration zone is treated with the gas in the second air inlet channel that has been dried in the first treatment zone, which effectively improves the utilization rate of resources. At the same time, the connection interface between the second return air channel and the second air inlet channel is set upstream of the connection interface between the third regeneration pipeline and the second air inlet channel, so that the return air gas introduced into the second return air channel can also enter the third regeneration pipeline through the second air inlet channel, which is used to regenerate the third regeneration zone and improve the utilization rate of the gas.

[0014] In some embodiments, a third heating component is provided in the third regeneration pipeline upstream of the third regeneration zone, and the third heating component is used to heat the gas flow provided to the third regeneration pipeline to a third temperature. By providing the third heating component in the third regeneration pipeline to increase the gas temperature in the third regeneration pipeline, the third heating component can be freely controlled and adjusted according to actual needs, and the flexibility of temperature adjustment is also improved.

[0015] In some embodiments, the second dehumidification wheel further includes a fourth regeneration zone, and the second treatment zone, the third regeneration zone, and the fourth regeneration zone are sequentially arranged along the rotation direction of the wheel; the fourth regeneration zone is connected to the second air inlet channel via a fourth regeneration pipeline, and a fourth heating component is arranged upstream of the fourth regeneration zone in the fourth regeneration pipeline, and the fourth heating component is used to heat the airflow provided to the fourth regeneration pipeline to a fourth temperature. The treatment zone of the second dehumidification wheel is also divided into a third regeneration zone and a fourth regeneration zone that can generate different temperatures, and the fourth regeneration pipeline is connected to the second air inlet channel, and a fourth heating component is arranged in the fourth regeneration pipeline to increase the gas temperature in the fourth regeneration pipeline. While the gas in the second air inlet channel is used to treat the treatment zone of the second dehumidification wheel, the heating power of the third heating component and the fourth heating component can be freely controlled and adjusted according to actual needs, which can save energy and improve the flexibility of temperature regulation.

[0016] In some embodiments, the first regeneration pipeline and the second regeneration pipeline are also connected to the outlet of the third regeneration zone respectively. The gas passing through the second air inlet channel enters the third regeneration pipeline for regenerating the third regeneration zone, and then the gas after the treatment in the third regeneration zone is connected to the first regeneration pipeline and the second regeneration pipeline to treat the first regeneration zone and the second regeneration zone, thereby improving the utilization rate of the gas.

[0017] In some embodiments, the rotary dehumidification device further comprises a dew point sensor, which is disposed downstream of the first processing zone of the first dehumidification rotary wheel. The gas data collected by the dew point sensor can be used to know the current state of the gas, so as to timely adjust the heating temperature of the first heating component and the second heating component.

[0018] In some embodiments, the rotary dehumidification device further includes a controller, which is connected to the dew point sensor and the second heating component respectively, and is used to control the second heating component to be turned on or off according to the gas data collected by the dew point sensor. The gas data is used to determine whether the treated gas meets the dew point temperature requirement, so as to timely adjust the heating temperature of the first heating component and the second heating component, which further improves the energy efficiency ratio of the rotary dehumidification device and reduces the regeneration energy consumption of the rotary dehumidification device.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0037] 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.

[0038] In order to meet the production process requirements, the relative humidity needs to be controlled in the production workshops of multiple processes in the battery factory. In order to meet the environmental humidity control requirements, dehumidification equipment needs to be installed. The rotary dehumidifier unit has the advantages of strong dehumidification capacity and large dehumidification capacity. The core component of the rotary dehumidifier is the dehumidification wheel. The surface of the dehumidification wheel is coated with a dehumidification medium. The dehumidification wheel is divided into a dehumidification treatment area and a regeneration area. Through slow rotation, the dehumidification wheel cycles alternately in the dehumidification treatment area and the regeneration area. During the working process, the fresh air inhaled from the outside and the fresh air to be treated are dehumidified through the dehumidification treatment area. The moisture of the fresh air is adsorbed by the dehumidification wheel and becomes dry gas and then sent to the workshop. After moisture absorption, the dehumidification wheel slowly rotates to the regeneration area, and the dehumidification medium is dehydrated and regenerated by the high-temperature dry airflow. In order to achieve low dew point air supply, the regeneration area of ​​the rotary dehumidifier needs to be blown with high-temperature dry airflow. The temperature of the high-temperature dry airflow usually exceeds 120°C under some working conditions.

[0039] Currently, due to the high regeneration temperature, the choice of heat source is subject to temperature restrictions. In some examples, in order to achieve a regeneration temperature above 120°C, a heater is usually used for direct heating. This not only consumes a lot of energy and causes waste of resources, but also leads to high regeneration heating operating costs for the rotary dehumidifier, thereby increasing the operating costs of the air conditioning system.

[0040] In order to solve the above technical problems, the present application divides the regeneration zone into a first regeneration zone and a second regeneration zone, uses a first regeneration pipeline that can generate a first temperature to perform preliminary regeneration on the first regeneration zone, and then uses a second regeneration pipeline that can generate a second temperature to perform deep regeneration on the second regeneration zone. Through the partitioned and step-temperature regeneration method, the heating efficiency of the rotary dehumidifier is improved, and the regeneration heating operation energy consumption of the rotary dehumidifier is reduced. At the same time, the return air in the room is introduced through the first return air channel, which further effectively reduces the energy consumed in the first regeneration pipeline and the second regeneration pipeline to increase the air flow temperature, and also reduces the operating cost of the rotary dehumidifier.

[0041] A rotary dehumidifier is disclosed in an embodiment of the present application. The rotary dehumidifier can be used, but is not limited to, for regulating the air humidity in a power battery workshop. Any workshop that requires air humidity regulation can use the rotary dehumidifier of the present application, including but not limited to: gas drying in a semiconductor manufacturing workshop to keep the air in the workshop within a stable humidity range to protect semiconductor products and production equipment from being affected by humidity; gas drying in a pharmaceutical manufacturing workshop to keep the air in the workshop within a stable humidity range to protect the pharmaceuticals from being affected by humidity so as not to reduce the efficacy of the pharmaceuticals.

[0042] The present application embodiment provides a rotary dehumidification device 100, such as Figures 1 to 3 As shown, Figure 1 A schematic structural diagram of a dual-rotor rotary dehumidification device provided in an embodiment of the present application; Figure 2 A schematic diagram of the cross-sectional structure of a first dehumidification wheel provided in an embodiment of the present application; Figure 3A schematic structural diagram of a single-wheel rotary dehumidification device provided in an embodiment of the present application. The rotary dehumidifier device 100 includes a first air inlet channel 110, a first return air channel 121 and a first dehumidification wheel 130, wherein the first air inlet channel 110 is used to receive outdoor fresh air; the first return air channel 121 is used to receive indoor return air; the first dehumidification wheel 130 includes a first treatment zone 131, a first regeneration zone 132 and a second regeneration zone 133 which are arranged in sequence along the rotation direction of the wheel; the inlet of the first treatment zone 131 is connected to the first air inlet channel 110 for adsorbing moisture in the fresh air; the first regeneration zone 132 is connected to the first return air channel 121 through a first regeneration pipeline 141, and the first regeneration pipeline 141 is constructed to provide an airflow with a first temperature to the first regeneration zone 132; the second regeneration zone 133 is connected to the first return air channel 121 through a second regeneration pipeline 142, and the second regeneration pipeline 142 is constructed to provide an airflow with a second temperature to the second regeneration zone 133; wherein the second temperature is greater than or equal to the first temperature.

[0043] The first air inlet channel 110 is used to receive outdoor fresh air. Exemplarily, a gas regulating valve 111 may be provided at the entrance of the first air inlet channel 110 to control the velocity and flow rate of the fresh air; Exemplarily, the first air inlet channel 110 is also provided with a first filter 112 to filter out dust in the fresh air, and the first filter 112 may be a primary filter; Exemplarily, the first air inlet channel 110 is also provided with a surface cooler, and the surface cooler is used to cool down the received fresh air. In order to improve the cooling effect, multiple surface coolers may be provided as required, for example, a first surface cooler 113 and a second surface cooler 114 may be provided in sequence. It should be noted that the arrangement order of the first filter 112 and the surface cooler may be determined as required.

[0044] The first dehumidification wheel 130 includes a first processing area 131, a first regeneration area 132, and a second regeneration area 133 arranged in sequence along the rotation direction of the wheel. The dehumidification principle of the first dehumidification wheel 130 is mainly to use the rotating wheel to absorb water molecules in the humid airflow to convert the humid airflow into a dry airflow to achieve the purpose of dehumidification. The dehumidification medium located in the first processing area 131 of the first dehumidification wheel 130 is used to absorb the moisture of the fresh airflow to dry the fresh airflow. The dehumidification medium located in the first processing area 131 rotates with the wheel to the first regeneration area 132 and the second regeneration area 133 after absorbing moisture. The dehumidification medium located in the first regeneration area 132 and the second regeneration area 133 is heated to achieve dehumidification capacity regeneration. The regenerated dehumidification medium rotates with the wheel to the first processing area 131 to achieve the recycling of the dehumidification medium.

[0045] The entrance of the first processing area 131 is connected to the first air inlet channel 110. A first blower 151 is arranged downstream of the first processing area 131. The first blower 151 can generate negative pressure to promote fresh air to enter from the first air inlet channel 110 and pass through the first processing area 131 for dehumidification and adsorption.

[0046] The first return air channel 121 is used to receive indoor return air. The indoor return air can be understood as a mixture of dried fresh air in the workshop and original air in the workshop. The humidity of the return air is lower than that of the undried fresh air gas outdoors.

[0047] The first regeneration pipeline 141 is connected to the first regeneration zone 132, and the first regeneration pipeline 141 can provide an airflow with a first temperature to achieve dehumidification capacity regeneration for the dehumidification medium passing through the first regeneration zone 132. For example, the first regeneration pipeline 141 is connected to an external heat source airflow, and the external hot airflow is used to achieve dehumidification capacity regeneration for the dehumidification medium passing through the first regeneration zone 132; for example, a heating element is arranged in the first regeneration pipeline 141 to perform gas heating. At the same time, the first regeneration pipeline 141 is connected to the first return air channel 121, and the return air of the first return air channel 121 is used to assist the dehumidification medium passing through the first regeneration zone 132 to achieve dehumidification capacity regeneration, which can reduce the energy consumption required to increase the temperature of the first regeneration pipeline 141.

[0048] The second regeneration pipeline 142 is connected to the second regeneration zone 133, and the second regeneration pipeline 142 can provide an airflow with a second temperature to achieve dehumidification capacity regeneration for the dehumidification medium passing through the second regeneration zone 133. For example, the second regeneration pipeline 142 can also be connected to an external heat source airflow, and the external hot airflow is used to achieve dehumidification capacity regeneration for the dehumidification medium passing through the second regeneration zone 133; for example, a heating element is arranged in the second regeneration pipeline 142 to heat the gas. At the same time, the second regeneration pipeline 142 is connected to the first return air channel 121, and the return air of the first return air channel 121 is used to assist the dehumidification medium passing through the second regeneration zone 133 to achieve dehumidification capacity regeneration, which can reduce the energy consumption required to increase the temperature of the second regeneration pipeline 142.

[0049] It should be noted that the airflow temperature provided by the second regeneration pipeline 142 is greater than or equal to the airflow temperature that can be provided by the first regeneration pipeline 141, that is, the second temperature is greater than or equal to the first temperature. The specific temperature can be determined according to actual needs. For example, the first temperature is 80° and the second temperature is 120°. The dehumidification medium after moisture absorption first passes through the first regeneration zone 132 of the first temperature with the rotor, which can take away most of the moisture of the dehumidification medium, and then passes through the second regeneration zone 133 of the second temperature, which takes away the remaining small amount of moisture of the dehumidification medium. By heating in different zones and at different temperatures, energy can be used more effectively and energy waste can be reduced.

[0050] In some embodiments, the rotary dehumidification device 100 further includes an air supply channel 170 and a moisture removal channel 180. A fourth cooler 171 and a second air blower 172 are disposed in the air supply channel 170 to cool the dried gas and pump it into the room. Figure 3 As shown, for a single-rotor dehumidification device, the air supply channel 170 is connected to the outlet of the first processing area 131; Figure 1 As shown, for the double-rotor dehumidification equipment, the air supply channel 170 is connected to the outlet of the treatment zone of the second rotor. A third air supply fan 181 is arranged in the dehumidification channel 180, and the dehumidification channel 180 is connected to the first regeneration zone 132 and the second regeneration zone 133 respectively, and is used to discharge the gas containing moisture passing through the first regeneration zone 132 and the second regeneration zone 133 to the outside.

[0051] By dividing the original single regeneration zone into a first regeneration zone 132 and a second regeneration zone 133 that can generate different temperatures, the first regeneration zone 132 is preliminarily regenerated by using the first regeneration pipeline 141 that can generate the first temperature to take away most of the moisture contained in the shallow surface of the first dehumidification wheel 130, and then the second regeneration pipeline 142 that can generate the second temperature is deeply regenerated in the second regeneration zone 133 to take away a small amount of moisture contained in the deep holes of the first dehumidification wheel 130. The heating efficiency of the rotary dehumidification equipment 100 is improved and the regeneration heating operation energy consumption of the rotary dehumidification equipment 100 is reduced through the partitioned and step-temperature regeneration method. At the same time, the indoor return air is introduced through the first return air channel 121. The indoor return air is drier than the outdoor fresh air, and the temperature is higher than the treated fresh air temperature, which further effectively reduces the energy consumed in the first regeneration pipeline 141 and the second regeneration pipeline 142 to increase the gas temperature.

[0052] According to some embodiments of the present application, Figure 1 As shown, in the first regeneration pipeline 141, a first heating component 1411 is arranged upstream of the first regeneration zone 132, and the first heating component 1411 is used to heat the airflow provided to the first regeneration pipeline 141 to a first temperature; in the second regeneration pipeline 142, a second heating component 1421 is arranged upstream of the second regeneration zone 133, and the second heating component 1421 is used to heat the airflow provided to the second regeneration pipeline 142 to a second temperature.

[0053] A first heating assembly 1411 is disposed upstream of the first regeneration zone 132, and the airflow provided to the first regeneration pipeline 141 is heated to a first temperature, for example, to 80°, by the first heating assembly 1411. The heated airflow passes through the first regeneration zone 132 to regenerate the dehumidification capacity of the dehumidification medium of the first regeneration zone 132. The first heating assembly 1411 is any device capable of heating air, for example, a heat pump.

[0054] A second heating assembly 1421 is disposed upstream of the second regeneration zone 133, and the airflow provided to the second regeneration zone 133 is heated to a second temperature, for example, to 120°, by the second heating assembly 1421. The heated airflow passes through the second regeneration zone 133 to regenerate the dehumidification capacity of the dehumidification medium of the second regeneration zone 133. The second heating assembly 1421 is any device capable of heating air, for example, an air heater.

[0055] It should be noted that when the first heating component 1411 can meet the dehumidification capacity regeneration requirement of the dehumidification medium, the second heating component 1421 may not be started, and the step-by-step heating method may be adopted to more effectively utilize energy and reduce energy waste. At the same time, in order to control the gas flow in the first regeneration pipeline 141 and the second regeneration pipeline 142, a gas regulating valve 111 is respectively provided in the first regeneration pipeline 141 and the second regeneration pipeline 142.

[0056] By setting a first heating component 1411 in the first regeneration pipeline 141 to increase the gas temperature in the first regeneration pipeline 141, and setting a second heating component 1421 in the second regeneration pipeline 142 to increase the gas temperature in the second regeneration pipeline 142, the heating power of the first heating component 1411 and the second heating component 1421 can be effectively and freely controlled and adjusted according to actual needs, thereby improving the flexibility of temperature regulation.

[0057] According to some embodiments of the present application, the heating efficiency of the first heating component 1411 is greater than the heating efficiency of the second heating component 1421 .

[0058] Heating efficiency refers to the ratio between the energy consumed and the heat generated by the heating component in the heating mode. The heating efficiency will be different for different heating components. The gas heat in the first regeneration pipeline 141 is provided by the first heating component 1411; the gas heat in the second regeneration pipeline 142 is provided by the second heating component 1421; most of the moisture in the dehumidification medium in the first dehumidification wheel 130 is carried away by the airflow in the first regeneration pipeline 141 through the first regeneration zone 132, and a small part of the moisture is carried away by the airflow in the second regeneration pipeline 142 through the second regeneration zone 133. The heating efficiency of the first heating component 1411 is greater than the heating efficiency of the second heating component 1421, thereby increasing the regeneration heating efficiency of the rotary dehumidification equipment 100 as a whole.

[0059] Exemplarily, a first heating component 1411 is provided upstream of the first regeneration zone 132, and a second heating component 1421 is provided upstream of the second regeneration zone 133, so that the heat source is divided into two different quality utilization conditions. The first heating component 1411 increases the heat of the gas in the first regeneration pipeline 141 to 70°C~80°C, meeting the regeneration temperature requirements under some working conditions of the rotary dehumidification equipment 100. When the dew point requirement of the rotary dehumidification equipment 100 is lower and the regeneration temperature requirement cannot be met by relying solely on the first heating component 1411, the second heating component 1421 is turned on for auxiliary heating to increase the heat of the gas in the second regeneration pipeline 142 to heat the airflow to 120°C or above.

[0060] By setting the heating efficiency of the first heating component 1411 to be greater than the heating efficiency of the second heating component 1421, it is possible to simultaneously utilize low-grade heat sources with high energy efficiency ratio and high-grade heat sources with low energy efficiency ratio, and it is also possible to realize the cascade utilization of heat sources of different grades, thereby improving the energy efficiency ratio of the regeneration operation of the rotary dehumidification equipment 100.

[0061] According to some embodiments of the present application, Figure 1 As shown, the first heating component 1411 includes a hot water heating element; and / or, the second heating component 1421 includes a steam heating element or an electric heating element.

[0062] The first heating component 1411 includes a hot water heating element 1412. The hot water heating element 1412 uses a hot water coil heater. The hot water is provided by a high-temperature heat pump water heater. The hot water is circulated inside the hot water heating element 1412 to increase the gas temperature. The heating efficiency of the hot water heating element can be greater than 3. The utilization rate of the first heating component 1411 as a low-grade heat source is increased to more than 80%. The second heating component 1421 includes a steam heating element or an electric heating element 1422. The heating efficiency of the steam heating element or the electric heating element 1422 is less than 1. The utilization rate of the second heating component 1421 as a high-grade heat source is reduced to less than 20%. The first heating component 1411 and the second heating component 1421 are used together to reduce the overall heating energy consumption.

[0063] In some embodiments, the second heating component 1421 may further include a hot water heating element 1412 and an electric heating element 1422 , and the hot water heating element 1412 and the electric heating element 1422 in the second heating component 1421 may be individually controlled to be turned on as required.

[0064] By adopting the hot water heating element 1412, the use of low-grade heat sources with high energy efficiency ratio can be achieved, and the regenerative heating operation energy consumption of the rotary dehumidification equipment 100 is reduced; by adopting the setting of the steam heating element or the electric heating element 1422, the temperature rise requirement not met by the first heating component 1411 can be compensated, and the regenerative heating operation energy consumption can be reduced.

[0065] According to some embodiments of the present application, Figure 3 As shown, the first regeneration zone 132 and the second regeneration zone 133 are both fan-shaped areas, and the central angle of the first regeneration zone 132 is greater than the central angle of the second regeneration zone 133; the central angle of the first regeneration zone 132 is greater than or equal to 60° and less than or equal to 75°, and the central angle of the second regeneration zone 133 is greater than or equal to 15° and less than or equal to 30°.

[0066] Most of the moisture in the dehumidification medium in the first dehumidification rotor 130 is carried away by the airflow in the first regeneration pipeline 141 through the first regeneration zone 132, and a small part is carried away by the airflow in the second regeneration pipeline 142 through the second regeneration zone 133. During the rotation of the first dehumidification rotor 130, the duration of the dehumidification medium after passing through the first treatment zone 131 in the first regeneration zone 132 should be greater than the duration in the second regeneration zone 133. The specific center angle of the first regeneration zone 132 and the center angle of the second regeneration zone 133 can be determined according to actual conditions. For example, the center angle of the first regeneration zone 132 is a first center angle α1, which is greater than or equal to 60° and less than or equal to 75°, and the second center angle of the second regeneration zone 133 is a second center angle α2, which is greater than or equal to 15° and less than or equal to 30°.

[0067] By setting the center angle of the first regeneration zone 132 between 60° and 75°, and the center angle of the second regeneration zone 133 between 15° and 30°, the dehumidification demand can be met and the energy consumption can be reduced as much as possible.

[0068] According to some embodiments of the present application, Figure 1 As shown, the rotary dehumidification device 100 further includes a second dehumidification wheel 160 and a second air inlet channel 150. The second dehumidification wheel 160 includes a second processing zone 161. The second air inlet channel 150 is connected to the outlet of the first processing zone 131 and the inlet of the second processing zone 161 respectively.

[0069] The rotary dehumidification device 100 further includes a second dehumidification rotary wheel 160, which also has a dehumidification medium. The second dehumidification rotary wheel 160 includes a second processing area 161 and a third regeneration area 162. One end of the second air inlet channel 150 is connected to the outlet of the first processing area 131, and the other end of the second air inlet channel 150 is connected to the inlet of the second processing area 161. The gas dried in the first processing area 131 is then dried again in the second processing area 161. The outlet of the second processing area 161 is connected to the air supply channel 170 to transport the dried gas to the room.

[0070] The dehumidification effect of the airflow can be further improved by adding the second dehumidification wheel 160 .

[0071] According to some embodiments of the present application, Figure 1 As shown, the rotary dehumidification equipment 100 also includes a second return air channel 122, which is constructed to be connected to the second air inlet channel 150, and is used to mix the return air of the second return air channel 122 and the fresh air processed by the first processing area 131 and provide them to the second processing area 161.

[0072] The return air channel 120 includes a second return air channel 122, which can be connected in parallel with the first return air channel 121 to receive the return air in the room. The second return air channel 122 is connected to the second air inlet channel 150, and the return air in the room is introduced into the second air inlet channel 150, which can not only supplement the air flow for the second air inlet channel 150 and reduce the demand for outdoor fresh air, but also balance the indoor gas pressure, and mix the return air of the second return air channel 122 with the fresh air processed by the first processing area 131 and provide it to the second processing area 161 for drying, so as to pump sufficient dry gas into the room.

[0073] In some embodiments, a first air supply fan 151, a third surface cooler 152 and a second filter 153 are also provided in the second air intake channel 150. The first air supply fan 151 is used to inhale the return air from the second return air channel 122 and the fresh air from the first air intake channel 110. The third surface cooler 152 is used to cool down the mixed air after the return air is inhaled into the second air intake channel 150. The second filter 153 is used to filter the mixed air after the return air is inhaled into the second air intake channel 150. The second filter 153 can be a medium efficiency filter.

[0074] Introducing indoor return air through the second return air duct 122 can make effective use of the indoor return air. While balancing the indoor air pressure, the indoor return air with low humidity can be reused, reducing production waste. At the same time, the introduced return air increases the gas volume, which can correspondingly reduce the energy consumed by introducing fresh air and drying. The fresh air processed in the first processing area 131 is mixed with the return air from the second return air duct 122, which also improves the uniformity of the airflow in the second air inlet duct 150.

[0075] According to some embodiments of the present application, Figure 1 and Figure 4 As shown, Figure 4 A schematic diagram of the cross-sectional structure of the second dehumidification wheel provided for an embodiment of the present application; the second dehumidification wheel 160 also includes a third regeneration zone 162, and the third regeneration zone 162 is connected to the second air inlet channel 150 through a third regeneration pipeline 143, and the connecting interface between the third regeneration pipeline 143 and the second air inlet channel 150 is located downstream of the connecting interface between the second return air channel 122 and the second air inlet channel 150.

[0076] The second dehumidification wheel 160 also includes a third regeneration zone 162, and the central angle of the third regeneration zone 162 is a third central angle α3, for example, the third central angle α3 is 90°. One end of the third regeneration pipeline 143 is connected to the second air inlet channel 150, and the other end of the third regeneration pipeline 143 is connected to the entrance of the third regeneration zone 162, so that the gas in the second air inlet channel 150 can be introduced into the third regeneration pipeline 143 to dehumidify and regenerate the third regeneration zone 162. And the connecting interface between the third regeneration pipeline 143 and the second air inlet channel 150 is arranged downstream of the connecting interface between the second return air channel 122 and the second air inlet channel 150. After the fresh air treated in the first processing zone 131 is mixed with the return air of the second return air channel 122, a part of the mixed gas is introduced into the third regeneration pipeline 143 for use, and the remaining mixed gas is dried through the second processing zone 161.

[0077] In some embodiments, a gas regulating valve 111 is further disposed in the third regeneration pipeline 143 .

[0078] By connecting the third regeneration pipeline 143 with the second air inlet channel 150, the third regeneration zone 162 is treated with the gas in the second air inlet channel 150 that has been dried by the first treatment zone 131, thereby effectively improving the utilization rate of resources. At the same time, the connecting interface between the second return air channel 122 and the second air inlet channel 150 is arranged upstream of the connecting interface between the third regeneration pipeline 143 and the second air inlet channel 150, so that the return air gas introduced into the second return air channel 122 can also enter the third regeneration pipeline 143 through the second air inlet channel 150, and be used for regenerating the third regeneration zone 162, thereby improving the utilization rate of the gas.

[0079] According to some embodiments of the present application, Figure 1 As shown, in the third regeneration pipeline 143, a third heating component 1431 is arranged upstream of the third regeneration zone 162, and the third heating component 1431 is used to heat the airflow provided to the third regeneration pipeline 143 to a third temperature.

[0080] A third heating assembly 1431 is disposed upstream of the third regeneration zone 162, and the airflow provided to the third regeneration pipeline 143 is heated to a third temperature, for example, to 80°, by the third heating assembly 1431. The heated airflow passes through the third regeneration zone 162 to regenerate the dehumidification capacity of the dehumidification medium of the third regeneration zone 162. The third heating assembly 1431 is any device capable of heating air, for example, a heat pump.

[0081] By disposing a third heating component 1431 in the third regeneration pipeline 143 to increase the temperature of the gas in the third regeneration pipeline 143, the third heating component 1431 can be effectively and freely controlled and adjusted according to actual needs, thereby improving the flexibility of temperature regulation.

[0082] According to some embodiments of the present application, Figure 5 As shown, Figure 5 A schematic diagram of the structure of another dual-rotor dehumidification device provided in an embodiment of the present application. The second dehumidification rotor 160 also includes a fourth regeneration zone, and the second treatment zone 161, the third regeneration zone 162 and the fourth regeneration zone are arranged in sequence along the rotation direction of the rotor; the fourth regeneration zone is connected to the second air inlet channel 150 through the fourth regeneration pipeline 144, and a fourth heating component 1441 is arranged upstream of the fourth regeneration zone in the fourth regeneration pipeline 144, and the fourth heating component 1441 is used to heat the airflow provided to the fourth regeneration pipeline 144 to a fourth temperature.

[0083] The second dehumidification rotor 160 may be the same as the first dehumidification rotor 130, and both are provided with two regeneration zones, namely, the third regeneration zone 162 and the fourth regeneration zone. The center angles of the third regeneration zone 162 and the fourth regeneration zone may also be the same as those of the first dehumidification rotor 130. The settings in the third regeneration pipeline 143 may be the same as those in the first regeneration pipeline 141; the settings in the fourth regeneration pipeline 144 may be the same as those in the second regeneration pipeline 142. The third regeneration pipeline 143 and the fourth regeneration pipeline 144 are respectively connected to the second air intake passage 150.

[0084] The processing area of ​​the second dehumidification wheel 160 is also divided into a third regeneration area 162 and a fourth regeneration area which can generate different temperatures, and the fourth regeneration pipeline 144 is connected to the second air inlet channel 150, and a fourth heating component 1441 is arranged in the fourth regeneration pipeline 144 to increase the gas temperature in the fourth regeneration pipeline 144. While the gas in the second air inlet channel 150 is used to process the processing area of ​​the second dehumidification wheel 160, the heating power of the third heating component 1431 and the fourth heating component 1441 can be freely controlled and adjusted according to actual needs, which can save energy and improve the flexibility of temperature regulation.

[0085] According to some embodiments of the present application, Figure 1 As shown, the first regeneration pipeline 141 and the second regeneration pipeline 142 are also connected to the outlet of the third regeneration zone 162 respectively.

[0086] One end of the first regeneration pipeline 141 is connected to the inlet of the first regeneration zone 132, and the other end of the first regeneration pipeline 141 is connected to the outlet of the third regeneration zone 162; one end of the second regeneration pipeline 142 is connected to the inlet of the second regeneration zone 133, and the other end of the second regeneration pipeline 142 is connected to the outlet of the third regeneration zone 162.

[0087] The gas enters the third regeneration pipeline 143 through the second air inlet channel 150, and is used to regenerate the third regeneration zone 162. The gas after treatment in the third regeneration zone 162 is then connected to the first regeneration pipeline 141 and the second regeneration pipeline 142, and the first regeneration zone 132 and the second regeneration zone 133 are treated to improve gas utilization.

[0088] According to some embodiments of the present application, Figure 1 As shown, the rotary dehumidification device 100 further includes a dew point sensor 173 , which is disposed downstream of the first processing zone 131 of the first dehumidification rotary wheel 130 .

[0089] The dew point sensor 173, i.e., a dew point meter, is an instrument that can directly measure the dew point temperature. The dew point sensor 173 is disposed on the air supply channel 170 to detect whether the dried gas meets the standard.

[0090] The gas data collected by the dew point sensor 173 can be used to know the current state of the gas, so as to adjust the heating temperature of the first heating component 1411 and the second heating component 1421 in time.

[0091] According to some embodiments of the present application, the rotary dehumidification device 100 also includes a controller, which is respectively connected to the dew point sensor 173 and the second heating component 1421, and the controller is used to control the second heating component 1421 to turn on or off according to the gas data collected by the dew point sensor 173.

[0092] The dew point sensor 173 is arranged on the air supply channel 170. First, the first heating component 1411 is turned on to heat the airflow of the first regeneration pipeline 141. The dew point sensor 173 is used to detect whether the dew point temperature of the airflow in the air supply channel 170 reaches the preset temperature. When the dew point temperature of the airflow does not meet the preset temperature, and the first heating component 1411 is in a fully turned on state, the controller is used to control the second heating component 1421 to be turned on according to the gas data, and the second heating component 1421 is used to heat the airflow in the second regeneration pipeline 142 to meet the preset dew point temperature of the gas in the air supply channel 170. When the dew point temperature of the airflow exceeds the preset temperature, the second heating component 1421 is lowered or turned off. This operating mode has a high energy efficiency ratio and can reduce the regeneration power consumption of the rotary dehumidification equipment 100.

[0093] The gas data is used to determine whether the treated gas meets the dew point temperature requirement, so as to timely adjust the heating temperature of the first heating component 1411 and the second heating component 1421, thereby further improving the energy efficiency ratio of the rotary dehumidification equipment 100 and reducing the regeneration energy consumption of the rotary dehumidification equipment 100.
