Description

Technical Field

[0001] The embodiments of this utility model relate to the field of moisture-proof technology for water conservancy and hydropower engineering equipment, specifically, to a moisture-proof treatment device for water conservancy and hydropower engineering equipment. Background Technology

[0002] As a vital infrastructure for the national economy, the operational stability of water conservancy and hydropower projects directly determines the safety and efficiency of the project. However, many critical pieces of equipment in these projects (such as gate hoist control modules, underwater water level sensors, pump motor junction boxes, and small components of generator excitation systems) face the challenge of harsh, humid environments. On the one hand, areas such as hydropower plant buildings, dam diversion corridors, and pump station control rooms are subject to water evaporation, groundwater seepage, and ventilation constraints, resulting in relative humidity levels that remain between 75% and 95% year-round. Furthermore, the diurnal temperature variation easily leads to condensation, causing liquid water vapor to adhere to equipment surfaces, terminals, and internal cavities. On the other hand, during the disassembly and maintenance of underwater equipment (such as submersible pumps and underwater current meters), moisture can easily remain in the sealing gaps and winding insulation layers. If not thoroughly removed, this moisture can accelerate the corrosion of metal components, reduce electrical insulation performance, and even cause serious malfunctions such as short circuits and equipment shutdowns after restarting, placing significant costs and safety pressures on project operation and maintenance.

[0003] Currently, common methods used in the industry for moisture-proofing the aforementioned equipment include placing desiccants (such as silica gel packets or calcium chloride granules) inside the equipment cavity and using vacuum drying chambers for batch processing of disassembled components. For example, moisture-damaged sensor probes are typically placed in a sealed bag with silica gel desiccant, relying on the desiccant to absorb moisture; small motor windings require being placed in a vacuum chamber for vacuuming and supplemented with low-temperature heating. However, these solutions have significant drawbacks: the desiccant's adsorption capacity is limited, requiring frequent disassembly and replacement, and cannot achieve long-term continuous moisture protection.

[0004] Existing moisture-proof technologies for water conservancy and hydropower engineering equipment have significant shortcomings in terms of "continuous dehumidification capacity," "environmental adaptability," and "equipment protection effectiveness," failing to meet the comprehensive moisture-proofing needs of different types of equipment under various operating conditions at engineering sites. Therefore, developing a moisture-proofing treatment device that can adapt to multiple scenarios in water conservancy and hydropower engineering while balancing dehumidification efficiency and equipment protection has become a key direction for solving industry pain points. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this utility model provide a moisture-proof treatment device for water conservancy and hydropower engineering equipment, which solves the technical problem of temperature changes affecting equipment lifespan during dehumidification in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a moisture-proofing treatment device for water conservancy and hydropower engineering equipment, comprising: The main body has a dehumidification chamber; A partition plate is disposed inside the dehumidification chamber, dividing the dehumidification chamber into a lower dehumidification chamber and an upper dehumidification chamber. The lower dehumidification chamber is used to accommodate the equipment to be dehumidified and to dehumidify the equipment. A moisture-guiding rod is installed through the partition plate, with its two ends extending into the lower dehumidification chamber and the upper dehumidification chamber, respectively. The moisture-guiding rod is used to absorb moisture in the lower dehumidification chamber and conduct it to the upper dehumidification chamber. The main body has an air vent that communicates with the upper dehumidification chamber.

[0007] For example, a moisture-proofing device for water conservancy and hydropower engineering equipment provided in at least one embodiment of this disclosure further includes: A first heating element is disposed in the upper dehumidification chamber. The first heating element is used to heat the moisture-conducting rod and remove moisture from the moisture-conducting rod.

[0008] For example, at least one embodiment of this disclosure provides a moisture-proofing device for water conservancy and hydropower engineering equipment. The air vent includes an air inlet and an air outlet; it also includes: An exhaust fan is installed at the air outlet and is used to draw in air to accelerate the air circulation in the upper dehumidification chamber.

[0009] For example, at least one embodiment of this disclosure provides a moisture-proofing device for water conservancy and hydropower engineering equipment. The main body has a gas inlet that communicates with the lower dehumidification chamber; The moisture-conducting rod has a connecting channel for connecting the lower dehumidification chamber and the upper dehumidification chamber.

[0010] For example, a moisture-proofing device for water conservancy and hydropower engineering equipment provided in at least one embodiment of this disclosure further includes: An air intake pipe is disposed on the main body, and the air intake pipe is connected to the gas inlet; A dehumidifier is detachably installed inside the air intake pipe, and the dehumidifier is used to remove water vapor from the air passing through the air intake pipe.

[0011] For example, at least one embodiment of this disclosure provides a moisture-proofing device for water conservancy and hydropower engineering equipment. A second heating element is provided inside the air intake pipe, which is used to increase the temperature of the air entering the lower dehumidification chamber.

[0012] For example, a moisture-proofing device for water conservancy and hydropower engineering equipment provided in at least one embodiment of this disclosure further includes: A shelf is disposed inside the lower dehumidification chamber, and there is an air passage gap between the shelf and the bottom of the lower dehumidification chamber. The shelf has air passage holes and is used to support the equipment to be dehumidified. The gas inlet is located below the shelf.

[0013] For example, at least one embodiment of this disclosure provides a moisture-proofing device for water conservancy and hydropower engineering equipment. The partition is a thermal insulation board.

[0014] For example, a moisture-proofing device for water conservancy and hydropower engineering equipment provided in at least one embodiment of this disclosure further includes: A switch baffle is slidably mounted on the main body, and the switch baffle can block the airflow inlet after sliding.

[0015] For example, at least one embodiment of this disclosure provides a moisture-proofing device for water conservancy and hydropower engineering equipment. The side wall of the air intake pipe is provided with a disassembly and assembly port, and the dehumidifier is used to be inserted into the disassembly and assembly port.

[0016] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the partition plate divides the dehumidification chamber into an independent lower dehumidification chamber and an upper dehumidification chamber, so that the lower dehumidification chamber forms a stable space to accommodate the equipment to be dehumidified, and avoids the airflow in the upper dehumidification chamber from directly interfering with the equipment to be dehumidified, thus providing a stable environment for the dehumidification process.

[0017] The main dehumidification chamber provides the basis for the compartment division of the partition plate. The partition plate ensures that the moisture transfer path of the moisture guide rod across the chamber is undisturbed. The moisture transfer function of the moisture guide rod provides a source for the water vapor to be discharged from the air vent. The air vent ensures that the water vapor conducted by the moisture guide rod is removed in time, ultimately forming a complete cycle of "moisture absorption in the lower dehumidification chamber - moisture transfer by the moisture guide rod - moisture discharge in the upper dehumidification chamber". This synergistic effect solves the problems of water vapor retention and low dehumidification efficiency in traditional single-chamber dehumidification equipment, and enables continuous dehumidification of equipment under dehumidification (some equipment components with environmental requirements, such as various temperature and humidity sensors) in a closed environment.

Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-4 As shown, this invention illustrates a moisture-proofing device for water conservancy and hydropower engineering equipment according to one embodiment of the present invention. The main body 1 forms a closed dehumidification chamber 11. Optionally, a door (not shown) communicating with the lower dehumidification chamber 12 is provided on the main body 1. One side of the door is rotatably connected to the main body 1 via a hinge, and the other side is detachably connected to the main body 1 via a latch. When the door is closed, a seal is formed between the door and the main body 1 to prevent direct communication between the lower dehumidification chamber 12 and the outside. A partition plate 2 is disposed within the dehumidification chamber 11, dividing the dehumidification chamber 11 vertically into a lower dehumidification chamber 12 and an upper dehumidification chamber 13. The lower dehumidification chamber 12 is located below the partition plate 2, and the upper dehumidification chamber 13 is located above the partition plate 2. Multiple through holes are provided on the partition plate 2, evenly distributed along the surface of the partition plate 2. A moisture-guiding rod 3 is installed in each through hole, with the outer wall of the moisture-guiding rod 3 fitting against the wall of the through hole. The moisture-guiding rod 3 (which can be a zeolite absorbent rod, a silica gel absorbent rod, or a ceramic-based absorbent rod, etc.) passes through the partition plate 2 through the through hole. One end of the moisture-guiding rod 3 extends out of the through hole and into the lower dehumidification chamber 12, while the other end extends out of the through hole and into the upper dehumidification chamber 13. An air vent is provided on the side wall of the main body 1 corresponding to the position of the upper dehumidification chamber 13. Optionally, there are two air vents, which are respectively located on opposite side walls of the main body 1, and both air vents communicate with the internal space of the upper dehumidification chamber 13.

[0028] The working process of the device is as follows: Open the chamber door using the latch, place the device to be dehumidified into the interior space of the lower dehumidification chamber 12, close the chamber door, and lock it with the latch to keep the lower dehumidification chamber 12 closed. Moisture in the lower dehumidification chamber 12 comes into contact with the end of the moisture-conducting rod 3 that extends into the chamber. The moisture-conducting rod 3 absorbs the moisture, which is then conducted along its internal structure from the end extending into the lower dehumidification chamber 12 to the end extending into the upper dehumidification chamber 13. Outside air enters through the air vent and carries away the humid air in the upper dehumidification chamber 13. During this process, the moisture-conducting rod 3 continuously absorbs moisture from the lower dehumidification chamber 12 and conducts it to the upper dehumidification chamber 13. The humid air in the upper dehumidification chamber 13 is continuously discharged through the air vent, thus removing moisture from the lower dehumidification chamber 12 and completing the dehumidification of the device to be dehumidified.

[0029] In this embodiment, the partition plate 2 divides the dehumidification chamber 11 into an independent lower dehumidification chamber 12 and an upper dehumidification chamber 13, so that the lower dehumidification chamber 12 forms a stable space to accommodate the equipment to be dehumidified, and avoids the air circulation in the upper dehumidification chamber 13 from directly interfering with the equipment to be dehumidified, providing a stable environment for the dehumidification process and preventing temperature changes in the upper dehumidification chamber 13 from affecting the lifespan of the equipment to be dehumidified in the lower dehumidification chamber 12.

[0030] The dehumidification chamber 11 of the main body 1 provides the basis for the chamber division of the partition plate 2. The division of the partition plate 2 ensures that the cross-chamber moisture transfer path of the moisture guide rod 3 is not disturbed. The moisture transfer function of the moisture guide rod 3 provides a source for the water vapor discharge from the air vent. The air vent ensures that the water vapor conducted by the moisture guide rod 3 is removed in time, ultimately forming a complete cycle of "moisture absorption in the lower dehumidification chamber 12 - moisture transfer by the moisture guide rod 3 - moisture discharge in the upper dehumidification chamber 13". This synergistic effect solves the problems of water vapor retention and low dehumidification efficiency in traditional single-chamber dehumidification equipment, and enables continuous dehumidification of equipment under dehumidification (some equipment components with environmental requirements, such as various temperature and humidity sensors) in a closed environment.

[0031] Furthermore, refer to Figure 3 As shown, a first heating element 4 is provided to improve the dehumidification efficiency in the upper dehumidification chamber 13.

[0032] The first heating element 4 is disposed in the upper dehumidification chamber 13. The first heating element 4 is a heating tube. A first temperature controller (not shown in the figure) is disposed on the outer wall of the main body 1. The first temperature controller is electrically connected to the first heating element 4 through a wire. The probe end of the first temperature controller extends into the upper dehumidification chamber 13 to detect the temperature in the upper dehumidification chamber 13 and control the start and stop of the first heating element 4.

[0033] During the workflow, after the moisture-conducting rod 3 conducts water vapor to the upper dehumidification chamber 13, the first temperature controller is activated. The first temperature controller controls the first heating element 4 to be powered on and heated according to a preset temperature threshold, such as 60°C. The heat generated by the heating element is transferred to the end of the moisture-conducting rod 3 that extends into the upper dehumidification chamber 13. The water vapor in the moisture-conducting rod 3 evaporates due to the heat, and the resulting moisture is discharged from the upper dehumidification chamber 13 with the airflow from the air vent. When the first temperature controller detects that the temperature in the upper dehumidification chamber 13 exceeds the preset threshold, it controls the first heating element 4 to be powered off to prevent the moisture-conducting rod 3 from being damaged by excessively high temperature.

[0034] In this embodiment, after the moisture-conducting rod 3 absorbs and conducts water vapor, the first heating element 4 accelerates the evaporation of water vapor, enabling the moisture-conducting rod 3 to quickly restore its moisture absorption capacity. Combined with the dehumidification function of the air vent, the dehumidification cycle of the lower dehumidification chamber 12 is further shortened. This solves the problem of slow water vapor discharge and easy saturation of moisture absorption capacity when relying solely on air circulation. At the same time, heating is carried out in the upper dehumidification chamber 13, and its temperature changes are less likely to affect the equipment to be dehumidified in the lower dehumidification chamber 12, avoiding the possibility of damage to the equipment to be dehumidified (especially temperature-sensitive equipment).

[0035] Furthermore, refer to Figure 4 As shown, in order to further improve the dehumidification efficiency in the upper dehumidification chamber 13, an exhaust fan 9 is installed on the air circulation outlet 15.

[0036] The air vent includes an air inlet 14 and an air outlet 15. The air inlet 14 is located on one side wall of the main body 1, corresponding to the upper dehumidification chamber 13. The air outlet 15 is located on the top side wall of the main body 1, corresponding to the upper dehumidification chamber 13. An exhaust fan 9 is bolted to the air outlet 15. The air inlet of the exhaust fan 9 is connected to the interior of the upper dehumidification chamber 13, and the air outlet of the exhaust fan 9 faces outwards from the main body 1. A fan switch (not shown in the figure) is installed on the outer wall of the main body 1. The fan switch is electrically connected to the exhaust fan 9 via a wire and is used to control the start and stop of the exhaust fan 9.

[0037] In the working process, the fan switch is turned on to run the exhaust fan 9. The exhaust fan 9 draws air into the upper dehumidification chamber 13 through the air circulation outlet 15, creating a negative pressure in the upper dehumidification chamber 13. Under the action of negative pressure, the outside air enters the upper dehumidification chamber 13 from the air circulation inlet 14, flows through the extension end of the moisture guide rod 3 and the first heating element 4, and carries the evaporated moisture out of the air circulation outlet 15 and is discharged by the exhaust fan 9.

[0038] In this embodiment, the exhaust fan 9 creates a directional and stable airflow circulation within the upper dehumidification chamber 13. Compared to airflow under natural pressure difference, the airflow speed is significantly increased, ensuring that the water vapor evaporated by the first heating element 4 quickly leaves the upper dehumidification chamber 13, preventing moisture from lingering in the chamber. After the first heating element 4 evaporates the water vapor, the exhaust fan 9 accelerates the discharge of humid air, preventing the humidity in the upper dehumidification chamber 13 from increasing and causing water vapor to seep back into the moisture-conducting rod 3.

[0039] Furthermore, refer to Figure 3 As shown, when the dehumidification device is a common device that can directly blow air to dehumidify, in order to further improve the moisture conduction efficiency of the moisture guide rod 3, a connecting channel 31 is opened in the moisture guide rod 3.

[0040] A gas inlet 121 is provided on the side wall of the main body 1 at the bottom position of the lower dehumidification chamber 12. A connecting channel 31 is provided along its own axis of the moisture guide rod 3. One end of the connecting channel 31 passes through the moisture guide rod 3 and extends into one end face of the lower dehumidification chamber 12, and the other end of the connecting channel 31 passes through the moisture guide rod 3 and extends into one end face of the upper dehumidification chamber 13, so that the lower dehumidification chamber 12 and the upper dehumidification chamber 13 are connected through the connecting channel 31.

[0041] During the process, outside air enters the lower dehumidification chamber 12 through the gas inlet 121. Part of the air carries water vapor after contacting the equipment to be dehumidified. It enters the upper dehumidification chamber 13 through the connecting channel 31 and merges with the water vapor conducted by the moisture guide rod 3. The air is then discharged from the air circulation outlet 15 by the exhaust fan 9. Another part of the air directly contacts the moisture guide rod 3 to assist the moisture guide rod 3 in absorbing water vapor.

[0042] In this embodiment, the opening of the gas inlet 121 provides an external air replenishment channel for the lower dehumidification chamber 12, preventing the air pressure inside the lower dehumidification chamber 12 from becoming too low due to moisture absorption by the moisture guide rod 3 and exhaust through the connecting channel 31. This ensures continuous air renewal around the equipment to be dehumidified, improving the comprehensiveness of moisture absorption. The connecting channel 31 of the moisture guide rod 3 constructs a direct airflow channel between the lower dehumidification chamber 12 and the upper dehumidification chamber 13, allowing the air carrying moisture in the lower dehumidification chamber 12 to directly enter and exit the upper dehumidification chamber 13. Combined with the moisture absorption and transfer function of the moisture guide rod 3, a dual-path moisture removal method of "moisture absorption + exhaust" is formed. Compared with relying solely on the moisture transfer of the moisture guide rod 3, the dehumidification efficiency of the lower dehumidification chamber 12 is significantly improved. The negative pressure generated by the exhaust fan 9 is conducted to the lower dehumidification chamber 12 through the connecting channel 31, accelerating the entry of external air from the gas inlet 121 and simultaneously driving the airflow within the lower dehumidification chamber 12, making it easier for moisture around the equipment to be dehumidified to be absorbed by the moisture guide rod 3 or exhausted through the connecting channel 31.

[0043] Furthermore, refer to Figure 4As shown, one end of the air intake pipe 5 is fixedly connected to the outer wall of the main body 1 via a flange (or welding), and the internal channel of the air intake pipe 5 is connected to the gas inlet 121. A disassembly and assembly port 51 is provided on the side wall of the air intake pipe 5. The dehumidifier 6 is a drawer-type drying box, the outer wall of which fits against the inner wall of the disassembly and assembly port 51. The drying box is inserted into the air intake pipe 5 through the disassembly and assembly port 51, and the pull-out end of the drying box extends outside the air intake pipe 5 to facilitate the removal and placement of the dehumidifier 6.

[0044] During the working process, outside air enters the air intake pipe 5 and flows through the dehumidifier 6. The moisture in the air is adsorbed by the dehumidifier 6, and the dried air enters the lower dehumidification chamber 12 through the gas inlet 121. When the dehumidifier 6 is saturated, the pull-out end of the drying box is pulled to remove the dehumidifier 6 from the disassembly and assembly port 51 for replacement.

[0045] In this embodiment, the flange connection structure between the air intake pipe 5 and the gas inlet 121 ensures the airtightness of the connection between the air intake pipe 5 and the main body 1, preventing outside air from directly entering the lower dehumidification chamber 12 through the connection gap without dehumidification. The drawer-type disassembly structure of the dehumidification component 6 allows for replacement without disassembling the air intake pipe 5. The dehumidification component 6 pre-treats the air entering the lower dehumidification chamber 12, removing moisture from the air and preventing the humidity in the lower dehumidification chamber 12 from rising again after the entry of humid outside air.

[0046] Furthermore, refer to Figure 4 As shown, when the dehumidification device is a common device that can directly blow hot air for dehumidification, a second heating element 7 is provided to improve the dehumidification efficiency of the device. The second heating element 7 is a heating tube, located on the side of the dehumidification device 6 away from the gas inlet 121. A second temperature controller (not shown in the figure) is provided on the outer wall of the main body 1. The second temperature controller is electrically connected to the second heating element 7 through a wire. The probe end of the second temperature controller extends into the air inlet pipe 5 to detect the air temperature inside the air inlet pipe 5 and control the start and stop of the second heating element 7.

[0047] In the workflow, the second temperature controller is activated. The second temperature controller controls the second heating element 7 to be powered on and heated according to the preset temperature threshold. When the air dehumidified by the dehumidifier 6 flows through the second heating element 7, it is heated. The heated air enters the lower dehumidification chamber 12 through the gas inlet 121. When it comes into contact with the equipment to be dehumidified, it can accelerate the evaporation of water vapor on the surface of the equipment.

[0048] In this embodiment, the second heating element 7 is located downstream of the dehumidifying element 6, ensuring that the air entering the lower dehumidifying chamber 12 is dehumidified before being heated, thus preventing condensation from forming inside the lower dehumidifying chamber 12 due to insufficient humidity reduction after heating. After the heated air enters the lower dehumidifying chamber 12, it raises the air temperature around the equipment to be dehumidified, lowers the relative humidity, and accelerates the evaporation of water vapor on the surface and inside the equipment. Combined with the moisture absorption of the moisture-conducting rod 3 and the exhaust of the connecting channel 31, the dehumidification time is further shortened. The dehumidifying element 6 removes most of the water vapor from the air, and the second heating element 7 further reduces the relative humidity by raising the temperature, thus increasing the dryness of the air entering the lower dehumidifying chamber 12. This not only prevents water vapor from being brought in by outside air but also actively accelerates the evaporation of water vapor from the equipment, solving the problem of difficulty in quickly removing water vapor from inside the equipment when only dehumidification is performed without heating.

[0049] Furthermore, refer to Figure 4 As shown, a shelf 8 is provided to further improve dehumidification efficiency. The shelf 8 is horizontally positioned within the lower dehumidification chamber 12. Optionally, a support column is provided on the inner wall of the main body 1 at a position below the shelf 8. An airflow gap is formed between the shelf 8 and the bottom of the lower dehumidification chamber 12. Multiple airflow holes 81 are provided on the shelf 8, evenly distributed along the surface of the shelf 8, with the axis of the airflow holes 81 perpendicular to the surface of the shelf 8. The opening of the gas inlet 121 is lower than the bottom surface of the shelf 8, allowing the gas inlet 121 to communicate with the airflow gap.

[0050] In the working process, the air entering from the gas inlet 121 first enters the air circulation gap, diffuses evenly along the gap, and then flows upward through the air circulation hole 81 of the shelf 8, completely enveloping the equipment to be dehumidified on the shelf 8. After absorbing the water vapor on the surface of the equipment, part of it is absorbed by the moisture guide rod 3, and part of it enters the upper dehumidification chamber 13 through the connecting channel 31.

[0051] In this embodiment, the support column below the shelf 8 ensures that a stable airflow gap is formed between the shelf 8 and the bottom of the lower dehumidification chamber 12, providing space for airflow. The uniform distribution of the airflow holes 81 allows air to fully cover the equipment to be dehumidified from bottom to top, avoiding damp dead corners at the bottom of the equipment due to poor airflow. The design of the gas inlet 121 being lower than the shelf 8 allows dry air to first fill the airflow gap and then flow upward through the airflow holes 81, ensuring uniform airflow distribution.

[0052] The dried and heated air processed by the air inlet pipe 5, dehumidifier 6, and second heating element 7 enters the air flow gap through the gas inlet 121 and acts evenly on the equipment to be dehumidified through the air flow hole 81, so that the water vapor in the equipment evaporates quickly. At the same time, the airflow drives the water vapor guide rod 3 or the connecting channel 31 to move, thereby improving the overall dehumidification efficiency.

[0053] Furthermore, refer to Figure 3As shown, when the dehumidification equipment is not suitable for dehumidification in a high-temperature environment, in order to reduce the impact of temperature fluctuations on the equipment performance, the partition plate 2 is set as a heat insulation plate, and the second heating element 7 is not used.

[0054] During the working process, when the first heating element 4 in the upper dehumidification chamber 13 is working, the partition plate 2 blocks the heat from being conducted to the lower dehumidification chamber 12, so that the temperature in the lower dehumidification chamber 12 remains stable.

[0055] In this embodiment, the heat insulation function of the partition plate 2 prevents heat transfer between the upper dehumidification chamber 13 and the lower dehumidification chamber 12, and prevents the high temperature generated by the first heating element 4 in the upper dehumidification chamber 13 from being conducted to the lower dehumidification chamber 12, which would cause the equipment to be dehumidified to be damaged due to excessive temperature.

[0056] Furthermore, refer to Figure 4 As shown, in order to improve the air circulation rate in the lower dehumidification chamber 12, a switch baffle 141 (which can slide to block the air circulation inlet 14) is provided.

[0057] The outer wall of the main body 1 is provided with a slide rail corresponding to the position of the air inlet 14, and the slide rail extends along the edge of the air inlet 14. The edge of the switch baffle 141 is embedded in the slide rail, and the switch baffle 141 slides with the slide rail. The area of ​​the switch baffle 141 is larger than the area of ​​the air inlet 14. The outer wall of the switch baffle 141 is provided with a handle (not shown in the figure) for pushing the switch baffle 141 to slide along the slide rail.

[0058] In this embodiment, the sliding structure of the switch baffle 141 enables the opening and closing control of the air flow inlet 14. When it is necessary to increase the air flow rate in the lower dehumidification chamber 12, the air flow inlet 14 is closed, so that the airflow enters only through the gas inlet 121, thereby increasing the air flow rate in the lower dehumidification chamber 12.
