Description

Technical Field

[0001] This utility model relates to the field of fluid processing technology, and in particular to a gas processing device. Background Technology

[0002] Industrial production processes may generate waste gases, which may be present in production workshops. These waste gases can affect the health of workers, and their accumulation can also adversely impact product manufacturing. For example, hydrogen sulfide gas is inevitably generated during the production of solid-state batteries, and it is considered a waste gas produced during this process. Hydrogen sulfide is a toxic gas, and its generation can negatively affect the health of workers.

[0003] One existing method to reduce the impact of hydrogen sulfide is to introduce inert gases such as nitrogen into the production workshop to create an oxygen-free and water-free environment. However, in large-scale production, due to the large space of the production workshop, a large amount of inert gas is needed to maintain the entire production workshop in an oxygen-free and water-free environment, which is costly. Another existing method to reduce the impact of hydrogen sulfide is to introduce fresh air into the production workshop to reduce the concentration of hydrogen sulfide. Furthermore, the fresh air has high humidity; therefore, it needs to be treated to a low dew point dry state before being introduced into the workshop, which is also costly. Summary of the Invention

[0004] The purpose of this invention is to provide a gas treatment device for removing moisture and waste gas from the gas and reducing treatment costs.

[0005] The objective of this utility model is achieved through the following technical solution: A gas processing apparatus, comprising: The dehumidifying impeller includes a dehumidifying zone for absorbing moisture from the gas and a regeneration zone for removing moisture from the impeller. The exhaust gas removal impeller includes an absorption zone for absorbing exhaust gas and a discharge zone for removing exhaust gas from the impeller. A processing air duct is used to supply processing airflow, the processing air duct passing through the dehumidification zone and the absorption zone to remove moisture and exhaust gas from the processing air; A desorption duct is provided for the flow of desorption air. The desorption duct passes through the regeneration zone and the discharge zone to remove moisture from the dehumidification rotor and waste gas from the waste gas removal rotor. The desorption duct includes a first exhaust duct connected to the discharge zone. The first exhaust duct is located downstream of the discharge zone along the gas flow direction. Gas passing through the discharge zone is discharged from the first exhaust duct. The first exhaust duct is independently separated from the dehumidification rotor and does not pass through the dehumidification rotor.

[0006] Preferably, the desorption duct further includes a first duct and a second duct, the first duct passing through the exhaust gas degassing impeller and communicating with the first exhaust duct, and the second duct passing through the dehumidification impeller and being independent of the first exhaust duct.

[0007] Preferably, it further includes a heat exchanger, through which the second air duct and the first exhaust air duct respectively pass, and the gases in the second air duct and the first exhaust air duct exchange heat within the heat exchanger; wherein the heat exchanger is located upstream of the dehumidifying impeller in the second air duct along the gas flow direction.

[0008] Preferably, multiple dehumidifying impellers are provided, including a first dehumidifying impeller and a second dehumidifying impeller. The first dehumidifying impeller is located on the flow path of the first air duct, and the first dehumidifying impeller is located downstream of the exhaust gas impeller along the gas flow direction in the processing air duct. The second dehumidifying impeller is located on the flow path of the second air duct.

[0009] Preferably, the desorption duct further includes a third duct, which passes through the exhaust zone of the exhaust gas degassing impeller and is connected to the outside; the third duct and the first exhaust duct are independent of each other.

[0010] Preferably, the processing air duct includes an air inlet path and a circulation path connected to the air inlet path. The circulation path circulates between the dehumidification rotor, the exhaust gas removal rotor, and the space to be treated, and outside air flows into the circulation path through the air inlet path. In the circulating flow path, the exhaust gas removal impeller is located upstream of the dehumidification impeller.

[0011] Preferably, multiple dehumidifying impellers are provided, including a first dehumidifying impeller and a second dehumidifying impeller, wherein the second dehumidifying impeller is located on the flow path of the air inlet flow path, and the first dehumidifying impeller is located on the flow path of the circulation flow path; Alternatively, multiple dehumidifying impellers may form a dehumidifying impeller group, which is located on the flow path of the circulating flow path, and the multiple dehumidifying impellers may be arranged sequentially along the gas flow direction.

[0012] Preferably, at least one of the dehumidifying impellers includes a cooling zone, and the desorption duct includes a cooling desorption duct that flows through the dehumidifying impeller. The air inlet of the cooling desorption duct is connected to the processing duct, and the cooling desorption duct passes sequentially through the cooling zone, the heater, and the regeneration zone of the dehumidifying impeller along the gas flow direction.

This method significantly reduces costs compared to existing methods that use inert gas to create an oxygen-free and water-free environment. By discharging the gas passing through the exhaust zone through a separate primary exhaust duct, damage to the dehumidifying impeller caused by exhaust gases is prevented, extending its lifespan and preventing reduced dehumidification efficiency due to exhaust gas damage over extended use.

[0018] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0019] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model. Example 1

[0020] like Figure 1 As shown, this utility model provides a gas treatment device for treating gas within a treatment space 100 to reduce the humidity and concentration of waste gas within the treatment space 100. The treatment space 100 can be a production workshop. The gas treatment device includes a dehumidifying rotor 1, a waste gas removal rotor 2, a treatment duct 3, and a desorption duct 4.

[0021] The dehumidifying impeller 1 is used to remove moisture from the gas. The dehumidifying impeller 1 includes a dehumidification zone 11 and a regeneration zone 12. When gas flows through the dehumidification zone 11 of the dehumidifying impeller 1, the dehumidification zone 11 absorbs moisture from the gas to dehumidify it. The regeneration zone 12 can be located in the flow path of the desorption air. The desorption air has a higher temperature, and it can heat the regeneration zone 12 to cause water to precipitate out. The precipitated water is discharged with the desorption air. The dehumidifying impeller 1 rotates continuously so that the same part of the dehumidifying impeller 1 absorbs moisture in the dehumidification zone 11 and then rotates to the regeneration zone 12 for drying.

[0022] One or more dehumidifying impellers 1 can be provided. When multiple dehumidifying impellers 1 are provided, they can be arranged sequentially along the gas flow direction and used to dehumidify the gas respectively. When multiple dehumidifying impellers 1 are provided, they include a first dehumidifying impeller 14 and a second dehumidifying impeller 15. One or more first dehumidifying impellers 14 and second dehumidifying impellers 15 can be provided respectively.

[0023] In some specific embodiments, at least one dehumidifying impeller 1 includes a cooling zone 13 located between the regeneration zone 12 and the dehumidification zone 11. The cooling zone 13 allows for the passage of ambient or low-temperature airflow to lower the temperature within it. When the same portion of the dehumidifying impeller 1 has dried in the regeneration zone 12, and that portion is at a higher temperature, it can rotate into the cooling zone 13 for cooling. After cooling, it rotates into the dehumidification zone 11 to ensure its dehumidification effect. Specifically, the first dehumidifying impeller 14 can be divided into a dehumidification zone 11, a regeneration zone 12, and a cooling zone 13. The second dehumidifying impeller 15 can be divided into a dehumidification zone 11 and a regeneration zone 12. That is, the first dehumidifying impeller 14 has a cooling zone 13, while the second dehumidifying impeller 15 does not.

[0024] The exhaust gas removal rotor 2 is used to remove exhaust gases from the gas. The exhaust gas removal rotor 2 includes an absorption zone 21 and a discharge zone 22. When gas flows through the absorption zone 21 of the exhaust gas removal rotor 2, the absorption zone 21 absorbs the exhaust gases in the gas to remove them. The discharge zone 22 can be located in the flow path of the desorption air. The desorption air has a higher temperature, heating the discharge zone 22 and causing the exhaust gases absorbed in the discharge zone 22 to precipitate out. The precipitated exhaust gases are discharged with the desorption air. The exhaust gas removal rotor 2 rotates continuously, so that the same part of the rotor 2 absorbs exhaust gases in the absorption zone 21 and then rotates to the discharge zone 22 to remove the exhaust gases. The exhaust gas can be hydrogen sulfide, and the exhaust gas removal rotor 2 can specifically be a rotor used to remove hydrogen sulfide from the gas.

[0025] The processing air duct 3 is used to supply processing airflow. The processing air may include the internal gas of the space to be treated 100 and fresh air introduced from the outside. The processing air duct 3 may pass through the dehumidification zone 11 and the absorption zone 21, so that the processing air can pass through the dehumidification zone 11 to remove moisture in the processing air, and the processing air can pass through the absorption zone 21 to remove exhaust gas in the processing air.

[0026] In some specific embodiments, the processing air duct 3 passes through the space to be treated 100, so that the gas in the space to be treated 100 is mixed with the processing air and flows through the dehumidification zone 11 and the absorption zone 21 to remove moisture and waste gas. The gas that has undergone moisture and waste gas removal can flow into the space to be treated 100 to reduce the humidity and waste gas concentration in the space to be treated 100. By continuously directing the gas in the space to be treated 100 to the dehumidification zone 11 and the absorption zone 21, and by allowing the gas passing through the dehumidification zone 11 and the absorption zone 21 to flow back into the space to be treated 100, the gas in the space to be treated 100 can be continuously treated to ensure that the humidity and waste gas concentration in the space to be treated 100 meet the requirements.

[0027] The processing air duct 3 may specifically include an air inlet path 31 and a circulation path 32 connected to the air inlet path 31. The circulation path 32 passes through the dehumidification rotor 1, the exhaust gas removal rotor 2, and the space to be treated 100, forming a closed loop. The processing air in the circulation path 32 circulates between the dehumidification rotor 1, the exhaust gas removal rotor 2, and the space to be treated 100. Specifically, the processing air flows through the exhaust gas removal rotor 2, the dehumidification rotor 1, and the space to be treated 100 in sequence. That is, the processing air first passes through the exhaust gas removal rotor 2 for exhaust gas removal before flowing to the dehumidification rotor 1, preventing the exhaust gas in the processing air from damaging the dehumidification rotor 1.

[0028] When multiple dehumidifying impellers 1 are configured, the circulation path 32 can pass through some or all of the dehumidifying impellers 1. For example, when the multiple dehumidifying impellers 1 include a first dehumidifying impeller 14 and a second dehumidifying impeller 15, the circulation path 32 can pass through the first dehumidifying impeller 14 but not through the second dehumidifying impeller 15.

[0029] In the circulating flow path 32, to ensure the treatment effect of the dehumidifying impeller 1 and the exhaust gas removal impeller 2 on the treated air, surface coolers 321 are respectively installed upstream of the first dehumidifying impeller 14 and upstream of the exhaust gas removal impeller 2 along the gas flow direction. The treated air flows to the first dehumidifying impeller 14 for dehumidification after being cooled by the corresponding surface cooler 321, and flows to the exhaust gas removal impeller 2 for exhaust gas removal after being cooled by the corresponding surface cooler 321. In addition, a surface cooler 321 can also be installed upstream of the space to be treated 100, and the treated air flows into the space to be treated 100 after being cooled by the surface cooler 321.

[0030] To ensure the air quality within the treatment space 100, a medium-efficiency filter 322 is installed upstream of the treatment space 100 along the gas flow direction. The treatment air flows into the treatment space 100 after being filtered by the medium-efficiency filter 322.

[0031] One end of the air intake path 31 is connected to the outside so that the air intake path 31 can receive fresh air from the outside. The other end of the air intake path 31 is connected to the circulation path 32 so that the fresh air in the air intake path 31 can flow into the circulation path 32. By mixing the fresh air with the gas in the circulation path 32, the concentration of exhaust gas in the gas can be reduced, and fresh air can be introduced into the space to be treated 100 to improve the air quality in the space to be treated 100.

[0032] The connection between the air inlet flow path 31 and the circulation flow path 32 can be located downstream of the space to be treated 100 and upstream of the exhaust gas removal rotor 2. That is, the gas flowing out of the space to be treated 100 first mixes with the fresh air in the air inlet flow path 31 and then flows to the exhaust gas removal rotor 2 and the first dehumidification rotor 14 for exhaust gas removal and dehumidification.

[0033] To ensure the quality of the fresh air flowing into the circulation path 32, a pre-filter 311 can be installed on the air inlet path 31. The fresh air flows into the circulation path 32 after being filtered by the pre-filter 311. In addition, an air valve 312 and a surface cooler 321 can also be installed on the air inlet path 31. The air valve 312 controls the opening and closing of the air inlet path 31 and the gas flow rate within it. The surface cooler 321 cools the fresh air before it flows into the circulation path 32.

[0034] In some specific embodiments, when multiple dehumidifying impellers 1 are provided, the air inlet path 31 can pass through a portion of the dehumidifying impellers 1. For example, the air inlet path 31 passes through a second dehumidifying impeller 15, which is located downstream of the pre-filter 311 and the surface cooler 321 on the air inlet path 31. Fresh air in the air inlet path 31 flows into the circulation path 32 after sequentially passing through the pre-filter 311, the surface cooler 321, and the dehumidification zone 11 of the second dehumidifying impeller 15.

[0035] In this embodiment, there may be two dehumidifying impellers 1, namely a first dehumidifying impeller 14 and a second dehumidifying impeller 15. The first dehumidifying impeller 14 is located on the circulation flow path 32, and the second dehumidifying impeller 15 is located on the air inlet flow path 31.

[0036] In another embodiment, reference Figure 3 There may be only one dehumidifying impeller 1. The dehumidifying impeller 1 is the first dehumidifying impeller 14, which is located on the circulation path 32.

[0037] In yet other embodiments, reference is made to Figure 4 The dehumidifying impeller 1 can be configured with three impellers: two second dehumidifying impellers 15 and one first dehumidifying impeller 14, forming a dehumidifying impeller group 16. This dehumidifying impeller group 16 is located on the circulation path 32. The multiple dehumidifying impellers 1 within the dehumidifying impeller group 16 are arranged sequentially along the gas flow direction; for example, two second dehumidifying impellers 15 and one first dehumidifying impeller 14 are arranged sequentially along the gas flow direction. The processing air in the circulation path 32 passes sequentially through the three dehumidifying impellers 1 for multi-stage dehumidification, improving the dehumidification effect on the processing air.

[0038] Reference Figure 1 The desorption duct 4 is used to supply desorption airflow. The desorption duct 4 passes through the regeneration zone 12 of the dehumidification rotor 1 and the exhaust zone 22 of the exhaust gas removal rotor 2. The desorption air is heated to form hot air before being blown into the regeneration zone 12 and the exhaust zone 22. The hot desorption air acts on the regeneration zone 12 to cause the water in the regeneration zone 12 to be separated and carried away by the desorption air, and the hot desorption air acts on the exhaust zone 22 to cause the exhaust gas in the exhaust zone 22 to be separated and carried away by the desorption air.

[0039] The desorption duct 4 includes a first exhaust duct 41 and a second exhaust duct 46. The upstream of the first exhaust duct 41 is connected to the exhaust zone 22 and located downstream of the exhaust zone 22 along the gas flow direction. The downstream of the first exhaust duct 41 is connected to the outside, allowing gas passing through the exhaust zone 22 to be discharged to the outside via the first exhaust duct 41. The first exhaust duct 41 is separated from the dehumidification rotor 1 and does not pass through the dehumidification rotor 1 to prevent gas passing through the exhaust zone 22 from flowing towards the dehumidification rotor 1. Gas passing through the exhaust zone 22 carries waste gas precipitated in the exhaust zone 22, which may damage the dehumidification rotor 1 when acting on it. By allowing the gas flowing through the exhaust zone 22 to be discharged through the first exhaust duct 41, damage to the dehumidification rotor 1 caused by the gas passing through the exhaust zone 22 can be prevented. One end of the second exhaust duct 46 is connected to the outside, and the other end is connected to the regeneration zone 12 of the dehumidifying rotor 1, so that the gas passing through the regeneration zone 12 of the dehumidifying rotor 1 can be discharged to the outside through the second exhaust duct 46.

[0040] In this embodiment, the desorption duct 4 may further include a cooling desorption duct 47, a first duct 42, and a second duct 43. The air inlet of the cooling desorption duct 47 is connected to the processing duct 3, specifically to the circulation path 32 in the processing duct 3. The air inlet of the cooling desorption duct 47 is located downstream of the exhaust gas removal impeller 2 along the gas flow direction, so that part of the processing air flows into the cooling desorption duct 47 as regeneration air after being degassed by the exhaust gas removal impeller 2. Furthermore, the air inlet of the cooling desorption duct 47 may also be located downstream of the surface cooler 321 located upstream of the first dehumidification impeller 14, so that the gas flows into the cooling desorption duct 47 after being cooled by the surface cooler 321 located upstream of the first dehumidification impeller 14.

[0041] The cooling desorption duct 47 passes through the cooling zone 13 of the dehumidifying impeller 1 and extends towards the regeneration zone 12 of the dehumidifying impeller 1 after passing through a heater 45. A portion of the gas in the circulation path 32 flows into the desorption duct 4 as desorption air, which then flows to the cooling zone 13 to cool it. The same portion of the first dehumidifying impeller 14, after being cooled in the cooling zone 13, rotates to the dehumidifying zone 11 to absorb moisture. By pre-cooling the dehumidifying zone 13, the temperature of the dehumidifying zone 11 can be reduced, thereby improving its dehumidification effect. The gas passing through the cooling zone 13 first absorbs heat from the cooling zone 13, and then is heated by the heater 45 to form hot air, which is blown towards the regeneration zone 12 to dry it.

[0042] One end of the first air duct 42 is connected to the regeneration zone 12 of the first dehumidifying impeller 14 and is used to receive the gas passing through the regeneration zone 12 of the first dehumidifying impeller 14. The other end of the first air duct 42 passes through the exhaust zone 22 of the exhaust gas impeller 2 and is connected to the first exhaust air duct 41. A heater 45 is provided on the first air duct 42. The gas passing through the regeneration zone 12 of the first dehumidifying impeller 14 is heated by the heater 45 on the first air duct 42 and then passes through the exhaust zone 22 to carry away the exhaust gas released from the exhaust zone 22. The gas carrying the exhaust gas released from the exhaust zone 22 flows to the first exhaust air duct 41 and is then discharged to the outside, preventing the exhaust gas from damaging the dehumidifying impeller 1.

[0043] The second air duct 43 passes through the regeneration zone 12 of the second dehumidification rotor 15 and is independent of the first exhaust air duct 41 to prevent exhaust gas in the first exhaust air duct 41 from flowing into the second air duct 43 and damaging the second dehumidification rotor 15. To utilize the waste heat in the first exhaust air duct 41, a heat exchanger 5 can also be installed on the desorption air duct 4. The second air duct 43 and the first exhaust air duct 41 both pass through the heat exchanger 5. In the first exhaust air duct 41, the heat exchanger 5 is located downstream of the exhaust zone 22; in the second air duct 43, the heat exchanger 5 is located upstream of the second dehumidification rotor 15. The gas passing through the exhaust zone 22 is at a higher temperature and flows towards the heat exchanger 5, while the gas upstream in the second air duct 43 is at a lower temperature and flows into the heat exchanger 5 to exchange heat with the gas passing through the exhaust zone 22, thereby utilizing the waste heat in the first exhaust air duct 41 and initially heating the gas in the second air duct 43. The heat exchanger 5 can be made of a material with good thermal conductivity to conduct the heat in the first exhaust duct 41 to the second duct 43, so as to ensure the heat absorption effect of the second duct 43 in the heat exchanger 5.

[0044] A heater 45 may also be installed on the second air duct 43. The heater 45 on the second air duct 43 is located upstream of the second dehumidifying impeller 15 and downstream of the heat exchanger 5. The gas in the second air duct 43 is first preheated by the heat exchanger 5 and then flows to the heater 45 for reheating. The gas heated by the heater 45 flows to the regeneration zone 12 of the second dehumidifying impeller 15. The end of the second air duct 43 is connected to the second exhaust air duct 46 so that the gas passing through the regeneration zone 12 of the second dehumidifying impeller 15 is discharged through the second exhaust air duct 46.

[0045] One or more fans 33 can be installed on the processing air duct 3 and the desorption air duct 4 respectively. The fans 33 are used to drive the gas to flow in the processing air duct 3 and the desorption air duct 4 along a predetermined path.

[0046] Reference Figure 1When treating the gas in the space to be treated 100, fresh air from the outside passes through the pre-filter 311 and the surface cooler 321 on the air inlet flow path 31 and flows to the treatment zone of the second dehumidification rotor 15 to dehumidify the gas. The gas passing through the treatment zone of the second dehumidification rotor 15 mixes with the gas in the space to be treated 100 to form treatment air. The treatment air is cooled by the surface cooler 321 and then flows to the absorption zone 21 of the exhaust gas removal rotor 2 to remove the exhaust gas in the gas. After passing through the exhaust gas removal rotor 2 and being cooled by the surface cooler 321, part of the gas flows into the cooling desorption air duct 47, and the other part flows to the treatment zone of the first dehumidification rotor 14. The gas passing through the treatment zone of the first dehumidification rotor 14 is cooled by the surface cooler 321 and filtered by the medium-efficiency filter 322 before flowing to the space to be treated 100.

[0047] Gas in the cooling desorption duct 47 passes through the cooling zone 13 of the first dehumidifying impeller 14 and is heated by the heater 45 before flowing to the regeneration zone 12 of the first dehumidifying impeller 14 to remove moisture from the regeneration zone 12. Gas passing through the regeneration zone 12 of the first dehumidifying impeller 14 flows from the first duct 42, is heated by the heater 45, and flows to the exhaust zone 22 of the exhaust gas impeller 2 to remove exhaust gas from the exhaust zone 22. Gas passing through the exhaust zone 22 flows from the first exhaust duct 41, passes through the heat exchanger 5, and is discharged to the outside. Gas in the second duct 43 undergoes heat exchange in the heat exchanger 5 and is heated by the heater 45 before flowing to the regeneration zone 12 of the second dehumidifying impeller 15 to remove moisture from the regeneration zone 12. Gas passing through the regeneration zone 12 of the second dehumidifying impeller 15 is discharged from the second exhaust duct 46. Example 2

[0048] This embodiment is basically the same as Embodiment 1, except that, as shown in the following description... Figures 2 to 4 In this embodiment, the desorption duct 4 includes a cooling desorption duct 47, a first duct 42, a first exhaust duct 41, a second exhaust duct 46, and a third duct 44. The cooling desorption duct 47 is configured in the same way as in Embodiment 1. One end of the first duct 42 is connected to the regeneration zone 12 of the first dehumidifying impeller 14 and is used to receive the airflow passing through the regeneration zone 12 of the first dehumidifying impeller 14. Then, the airflow flows from the first duct 42 to the regeneration zone 12 of the second dehumidifying impeller 15 after being heated by the heater 45, and is discharged through the second exhaust duct 46. Alternatively, the airflow passing through the regeneration zone 12 of the first dehumidifying impeller 14 flows directly from the first duct 42 to the second exhaust duct 46 and is discharged.

[0049] The third air duct 44 is an independent air duct, and it passes through the exhaust zone 22 of the exhaust gas impeller 2 and connects to the first exhaust air duct 41. A heater 45 is installed on the third air duct 44, and the heater 45 is located upstream of the exhaust gas impeller 2. After the outside fresh air flows into the third air duct 44, the fresh air is heated by the heater 45 and then passes through the exhaust zone 22 of the exhaust gas impeller 2. After passing through the exhaust zone 22, the gas is discharged to the outside through the first exhaust air duct 41.

[0050] Reference Figure 2 When treating the gas in the treatment space 100, fresh air from the outside passes through the pre-filter 311 and the surface cooler 321 on the air inlet flow path 31 and flows to the treatment area of ​​the second dehumidification rotor 15 for dehumidification. The gas passing through the treatment area of ​​the second dehumidification rotor 15 mixes with the gas that has passed through the exhaust gas removal rotor 2 to form treatment air. After being cooled by the surface cooler 321, part of the treatment air flows into the cooling desorption air duct 47, and the other part flows to the treatment area of ​​the first dehumidification rotor 14. The gas passing through the treatment area of ​​the first dehumidification rotor 14 is cooled by the surface cooler 321 and filtered by the medium-efficiency filter 322 before flowing to the treatment space 100. The gas in the treatment space 100 flows to the absorption area 21 of the exhaust gas removal rotor 2. The gas passing through the absorption area 21 mixes with the fresh air in the air inlet flow path 31 and is circulated again.

[0051] Gas in the cooling desorption duct 47 passes through the cooling zone 13 of the first dehumidifying impeller 14 and is heated by the heater 45 before flowing to the regeneration zone 12 of the first dehumidifying impeller 14 to remove moisture from the regeneration zone 12.
