Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a gas dehumidification device. Background Technology

[0002] With the rapid development of rail transit technology, the reliability requirements for key assembly processes are becoming increasingly stringent. During the vehicle unloading process, air-cooled equipment such as air springs needs to be charged, a process that often requires the use of an air compressor to meet the required air supply pressure.

[0003] In related technologies, the air source output by the air compressor is heated due to compression, and condensation water is easily generated during the transportation process. Currently, manual dehumidification is usually used, that is, the staff removes the water vapor at the delivery pipe opening by wiping or external heating.

[0004] However, in the above methods, moisture may remain inside the delivery pipeline, which can cause corrosion to the ventilation equipment in the vehicle, seriously affecting the overall vehicle performance and service life, resulting in lower vehicle operation safety. Summary of the Invention

[0005] This application provides a gas dehumidification device to address the problem of low safety during vehicle operation.

[0006] In a first aspect, this application provides a gas dehumidification device, comprising: a housing, a ventilation cooling pipe, and a separator, wherein:

[0007] The ventilation and cooling pipes are located inside the enclosure, while the separator is located outside the enclosure. The enclosure contains coolant.

[0008] The ventilation duct includes a first air inlet and a first air outlet, and the separator includes a second air inlet and a second air outlet, with the first air outlet connected to the second air inlet.

[0009] The ventilation duct is used to condense the gas input from the air compressor based on coolant, and to input the condensed gas into the second air inlet of the separator through the first air outlet;

[0010] The separator is used to separate oil and water in the condensed gas and to deliver the separated gas to the vehicle's gas-using equipment.

[0011] In one possible implementation, the gas dehumidification device further includes a frame, wherein...

[0012] The frame has an internal cavity, and the box is fixed in the cavity.

[0013] In one possible implementation, the frame further includes a connecting plate, to which the separator is connected.

[0014] In one possible implementation, the ventilation cooling pipe is coiled inside the housing, and the height of the first air outlet is higher than the height of the first air inlet.

[0015] In one possible implementation, the separator further includes a separation device connected to a second air inlet and a second air outlet, respectively, the separation device being used to separate moisture from the condensed gas.

[0016] In one possible implementation, the gas dehumidification equipment further includes a humidity detection device, which is located at the second air outlet of the separator and is used to detect the humidity of the oil-water separated gas output from the second air outlet.

[0017] In one possible implementation, the gas dehumidification device further includes a display device connected to the housing, which is used to display the humidity detected by the humidity detection device.

[0018] In one possible implementation, the gas dehumidification device further includes a cooling device connected to the housing;

[0019] The cooling device is used to cool the coolant in the tank.

[0020] In one possible implementation, the cooling device includes a refrigerator and cooling pipes, with the refrigerator connected to the bottom of the frame and the cooling pipes disposed inside the housing.

[0021] The cooling device is specifically used to obtain the humidity detected by the humidity detection device. When the humidity is greater than or equal to the first threshold, it controls the refrigeration unit to start and transfer refrigerant into the refrigeration pipe to cool the coolant in the box. When the humidity is less than the first threshold, it controls the refrigeration unit to stop.

[0022] In one possible implementation, when the humidity detected by the humidity detection device is less than a first threshold, the oil-water separated gas is input into the vehicle's gas-using equipment.

[0023] The gas dehumidification equipment provided in this application includes a housing, a ventilation cooling pipe, and a separator. The ventilation cooling pipe is located inside the housing, and the separator is located outside the housing. The housing contains coolant. The ventilation cooling pipe includes a first air inlet and a first air outlet, and the separator includes a second air inlet and a second air outlet, with the first air outlet connected to the second air inlet. The ventilation cooling pipe is used to condense the gas input from the air compressor based on the coolant, and inputs the condensed gas into the second air inlet of the separator via the first air outlet. The separator is used to separate oil and water in the condensed gas and transmit the separated gas to the vehicle's air-using equipment. In the above structure, due to the combination of a housing with built-in coolant and a ventilation cooling pipe, the compressed gas can be efficiently and uniformly condensed, promoting sufficient condensation of water vapor. The external separator effectively removes moisture from the gas, ensuring dry air supply. This equipment can effectively prevent water vapor from appearing inside the delivery pipeline, preventing corrosion problems in the air-using equipment. It eliminates the need for manual dehumidification, improves the air supply quality of urban rail vehicles, and thus improves the safety of vehicle operation. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0052] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. These should be regarded as exemplary and are only intended to illustrate the feasibility of implementing the technical solution of this application. However, it does not mean that the applicant has used or necessarily used the solution.

[0053] To facilitate understanding, the following will be combined with... Figure 1 The application scenarios applicable to the embodiments of this application will be described.

[0054] Figure 1 This is a schematic diagram illustrating an application scenario provided in an embodiment of this application. Please refer to [link / reference]. Figure 1 It includes an air compressor 101, a gas dehumidification device 10, and a vehicle 102.

[0055] The air compressor 101 is connected to the gas dehumidification device 10, and the gas dehumidification device 10 is connected to the air supply device of the vehicle 102. The air compressor 101 can compress the air and deliver the compressed gas to the gas dehumidification device 10. The gas dehumidification device 10 dehumidifies the compressed gas and delivers the dehumidified dry gas to the air supply device of the vehicle 102 to complete the vehicle charging operation.

[0056] In related technologies, the air source output by the air compressor heats up during compression, easily causing condensation to form during delivery. Currently, manual dehumidification is commonly used, where workers remove moisture from the delivery pipe openings by wiping or external heating. However, in these methods, residual moisture may remain inside the delivery pipes, causing corrosion and other damage to the vehicle's ventilation equipment, severely impacting overall vehicle performance and lifespan, and resulting in lower vehicle operational safety.

[0057] To address the aforementioned issues, this application provides a gas dehumidification device comprising a housing, a ventilation cooling pipe, and a separator. The ventilation cooling pipe is disposed inside the housing, and the separator is disposed outside the housing. The housing contains coolant. The ventilation cooling pipe includes a first air inlet and a first air outlet, and the separator includes a second air inlet and a second air outlet, with the first air outlet connected to the second air inlet. The ventilation cooling pipe is used to condense the gas input from the air compressor based on the coolant, and to input the condensed gas into the second air inlet of the separator via the first air outlet. The separator is used to perform oil-water separation on the condensed gas and to transmit the oil-water separated gas to the vehicle's gas-using equipment. In the aforementioned structure, since the ventilation cooling pipes are housed within the enclosure, the coolant within the enclosure can efficiently and uniformly condense the gas within the ventilation cooling pipes. Furthermore, a separator effectively removes moisture from the gas, ensuring dry air supply. This equipment provides systematic dehumidification of the gas, effectively preventing residual moisture inside the pipes. It eliminates the need for frequent disassembly of vehicle pipelines, reducing manpower and material costs, and significantly lowering the probability of malfunctions in vehicle gas equipment due to moisture corrosion. This ensures the reliability of equipment operation, extends its service life, and eliminates the need for complex operating procedures. Moreover, this gas dehumidification process is adaptable to various rail transit scenarios requiring high gas dryness. By improving the dehumidification effect, it enhances the overall efficiency of vehicle air filling operations, thereby improving vehicle operational safety.

[0058] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0059] Figure 2 This is a schematic diagram of a gas dehumidification device provided in an embodiment of this application. Please refer to... Figure 2 As shown, the gas dehumidification device 10 provided in this embodiment includes a housing 100, a ventilation cooling pipe 200, and a separator 300, wherein:

[0060] The ventilation cooling pipe 200 is located inside the housing 100, and the separator 300 is located outside the housing 100. The housing 100 contains coolant.

[0061] In some embodiments, the housing 100 can be used to receive coolant and can also fix the ventilation cooling pipe 200, wherein the coolant can be a liquid such as water.

[0062] In some embodiments, the coolant level in the housing 100 needs to be higher than the height of the ventilation cooling pipe 200 so that the gas is sufficiently cooled in the ventilation cooling pipe 200 and condensate is generated.

[0063] In some embodiments, the housing 100 may be provided with a liquid inlet 103 and a liquid outlet 104. The liquid inlet 103 may be located at the top of the housing 100 to pour in the required coolant, and the liquid outlet 104 may be located on the side of the housing 100 near the bottom to drain the coolant from the housing 100. After the coolant is filled, a liquid inlet cap 105 may be provided to prevent the coolant from overflowing during the movement of the gas dehumidification device 10.

[0064] In some embodiments, a welded threaded joint may be provided on the side of the housing 100 near the bottom. The threaded joint may be connected to a drain component 106, which is used to drain the coolant in the housing 100. The drain component 106 may be a faucet or the like.

[0065] In some embodiments, the housing 100 may include a circulation pump. Specifically, the circulation pump may be located inside the housing 100 to effectively improve the uniformity of cooling by circulating the coolant.

[0066] In some embodiments, the material of the housing 100 can be a thin steel plate, for example, a high-strength cold-rolled steel plate with a thickness of 1 mm and a tensile strength greater than or equal to 500 MPa. The steel plate is both lightweight and rigid, with a single piece weighing less than or equal to 20 grams, and can enter extremely narrow spaces of as small as 6 mm × 6 mm.

[0067] The ventilation duct 200 includes a first air inlet 201 and a first air outlet 202, and the separator 300 includes a second air inlet 301 and a second air outlet 302. The first air outlet 202 is connected to the second air inlet 301.

[0068] The ventilation and cooling pipe 200 is coiled in the housing 100, and the height of the first air outlet 202 is higher than the height of the first air inlet 201.

[0069] Below, in conjunction with Figure 3 The ventilation and cooling pipes in the enclosure are explained through specific examples.

[0070] Figure 3 For a possible structural diagram of a ventilation cooling duct provided in this application embodiment, please refer to [link / reference]. Figure 3 The ventilation cooling duct 200 includes a duct with multiple continuous U-shaped bends, in which gas can flow back and forth. In this way, by increasing the flow path of gas in the ventilation cooling duct 200, the uniformity of gas cooling is increased and the efficiency of gas cooling is improved.

[0071] In some embodiments, the ventilation cooling pipe 200 can be spirally coiled inside the housing 100, that is, the pipe of the ventilation cooling pipe 200 rotates and coils around a central axis from bottom to top. The spiral radius of the pipe can be set according to the size of the housing, which can avoid the pipe from being too close to the housing wall and thus hindering the flow of coolant, while occupying as much radial space as possible in the housing.

[0072] It should be noted that when the pipe is coiled, it should be kept at an appropriate angle to the horizontal plane. This allows the condensed water droplets to flow back along the pipe wall under the influence of gravity and airflow as the gas rises within the pipe, reducing the amount of liquid water carried into the separator. The overall coiling trajectory can form a distribution that is denser at the bottom and sparser at the top. The denser coiling at the bottom can quickly lower the temperature of the newly entered high-temperature gas, while the looser coiling at the top can further condense the gas that has already been preliminarily cooled.

[0073] In some embodiments, the ventilation cooling pipe 200 can be coiled inside the housing 100 in a planar bend pattern. That is, the ventilation cooling pipe 200 makes multiple 180-degree bends within a plane at a certain height, and these planes are spaced apart inside the housing 100. The pipes within each plane exhibit a reciprocating bend pattern, with rounded corners at the bends to reduce airflow resistance. Furthermore, adjacent planes maintain a reasonable distance, and the bend trajectories of the upper and lower planes are staggered to provide convection channels for the coolant between the planes.

[0074] It should be noted that the extension length of the pipeline is determined in conjunction with the internal space of the enclosure to ensure that it can fully cover the enclosure area. Each plane is connected in series by a vertical short pipe. The first air inlet is connected to the beginning of the bottom plane, and the first air outlet is led out from the end of the top plane, using the height difference to assist the natural settling of condensate.

[0075] In some embodiments, the pipes containing the first air inlet 201 and the first air outlet 202 of the ventilation cooling pipe 200 pass through the housing 100, and the first air inlet 201 and the first air outlet 202 are located on one side of the housing. The first air inlet 201 is located at the bottom of the housing 100, and the first air outlet 202 is located at the top of the housing 100. In this way, the condensate in the ventilation cooling pipe 200 can flow back to the bottom of the pipe along the pipe wall under the action of gravity.

[0076] In some embodiments, the ventilation cooling duct 200 can be made of copper. Because copper has strong thermal conductivity, it can achieve rapid temperature conduction, thereby causing the gas in the ventilation cooling duct 200 to condense rapidly.

[0077] The ventilation cooling pipe 200 is used to condense the gas input from the air compressor based on coolant, and to input the condensed gas into the second air inlet 301 of the separator 300 through the first air outlet 202.

[0078] In some embodiments, when the gas flows through the ventilation cooling pipe 200 immersed in the coolant, the heat of the gas is transferred to the coolant through the pipe wall, and the temperature of the gas is reduced. When the gas temperature drops below the dew point, the water vapor inside the gas condenses and precipitates out, forming liquid water droplets that move forward with the airflow. The condensed gas is then transported to the second air inlet 301 of the separator 300 through the first air outlet 202.

[0079] The separator 300 is used to separate oil and water in the condensed gas and to deliver the separated gas to the gas-using equipment of the vehicle.

[0080] In some embodiments, the separator 300 is typically equipped with a multi-stage separation structure inside, where condensate in the gas is effectively collected and separated. When it is determined that the output gas meets the requirements, the gas can be transmitted to the gas-using equipment of the vehicle through the second air outlet 302. Sensors or the like can be installed to determine whether the humidity of the gas output by the separator 300 meets the requirements.

[0081] The gas dehumidification device 10 also includes a frame 400, wherein the interior of the frame 400 includes a cavity 401, and the housing 100 is fixed in the cavity 401.

[0082] In some embodiments, the frame 400 can be used to fix the housing 100 and the separator 300. The frame 400 includes a first connecting plate 402 and a second connecting plate 403. The first connecting plate 402 is disposed at the top of the frame 400 to form the top surface of the frame 400, and the second connecting plate 403 is disposed at the bottom of the frame 400 to form the bottom surface of the frame 400.

[0083] In some embodiments, the housing 100 may be disposed in the upper half of the cavity 401, with the top edge of the housing 100 fixedly connected to the first connecting plate 402, and the side edge of the housing 100 fixedly connected to the inner surface of the frame 400, that is, the housing 100 is fixedly disposed inside the cavity 401.

[0084] In some embodiments, the gas dehumidification device 10 further includes a plurality of wheels 500, which are used to support and move the frame 400. The plurality of wheels 500 are respectively connected to the second connecting plate 403. For example, the number of wheels 500 can be set to 4, wherein the position of each wheel 500 corresponds to the corner of the frame 400.

[0085] The frame 400 also includes a connecting plate 404, and the separator 300 is connected to the connecting plate 404 of the frame 400.

[0086] In some embodiments, the frame 400 can be made of aluminum profile material, and the frame 400 has dimensions of 40mm × 40mm × 20mm. The connection points of the frame 400 use aluminum angle brackets and stainless steel connecting plates, and are fixedly connected by bolts.

[0087] In some embodiments, the coolant in the housing 100 can be cooled by a refrigeration device, such as a refrigeration unit.

[0088] The working process of the gas dehumidification equipment is explained below:

[0089] When the air compressor 101 and the separator 300 are in the on state, the compressed gas generated by the air compressor 101 is delivered to the first air inlet 201 of the ventilation cooling pipe 200 through the hose. The gas flows in the ventilation cooling pipe 200, so that it can fully exchange heat with the coolant in the housing 100. The gas temperature drops rapidly, and the gas containing condensate is obtained, completing the gas condensation treatment. The condensed gas flows through the first air outlet 202 of the ventilation cooling pipe 200 and is delivered to the second air inlet 301 of the separator 300. The separator 300 separates the moisture in the gas, and the gas with separated moisture is delivered to the vehicle's air-using equipment through the second air outlet 302.

[0090] The gas dehumidification device provided in this application includes a housing, a ventilation cooling pipe, and a separator. The ventilation cooling pipe is disposed inside the housing, and the separator is disposed outside the housing. The housing contains coolant. The ventilation cooling pipe is used to condense the gas input from the air compressor based on the coolant, and inputs the condensed gas into the second air inlet of the separator through the first air outlet. The separator is used to perform oil-water separation treatment on the condensed gas and transmit the oil-water separated gas to the gas-using equipment of the vehicle. In the aforementioned structure, since the ventilation cooling pipes are housed within the enclosure, the coolant within the enclosure can efficiently and uniformly condense the gas within the ventilation cooling pipes. Furthermore, a separator effectively removes moisture from the gas, ensuring dry air supply. This equipment provides systematic dehumidification of the gas, effectively preventing residual moisture inside the pipes. It eliminates the need for frequent disassembly of vehicle pipelines, reducing manpower and material costs, and significantly lowering the probability of malfunctions in vehicle gas equipment due to moisture corrosion. This ensures the reliability of equipment operation, extends its service life, and eliminates the need for complex operating procedures. Moreover, this gas dehumidification process is adaptable to various rail transit scenarios requiring high gas dryness. By improving the dehumidification effect, it enhances the overall efficiency of vehicle air filling operations, thereby improving vehicle operational safety.

[0091] Based on any of the above embodiments, the following, in conjunction with Figure 4 , Figure 5 , Figure 6 and Figure 7 The structure of the gas dehumidification equipment is described in detail.

[0092] Figure 4 This is a schematic diagram of another gas dehumidification device provided in an embodiment of this application. Figure 5 for Figure 4 Left side view, Figure 6 for Figure 4 The right side view, Figure 7 for Figure 4 A top-down perspective view. See also... Figure 4 The separator 300 also includes a separation device 303, which is connected to the second air inlet 301 and the second air outlet 302 respectively. The separation device 303 is used to separate the moisture in the gas after condensation.

[0093] In some embodiments, the separation device 303 can employ a centrifugal flow guiding structure combined with a multi-layer filter screen for oil-water separation. Specifically, along the gas flow direction, the separation device 303 can first be equipped with spiral-shaped guide vanes. When the condensed gas enters from the second air inlet 301, the guide vanes guide the gas to rotate at high speed along the inner wall, generating centrifugal force. In this way, liquid water droplets mixed in the gas (because their density is greater than that of the gas) are thrown towards the inner wall of the separation device 303 under the action of centrifugal force, and settle down to the water collection chamber at the bottom of the separation device 303 under the action of gravity. The gas after centrifugal separation continues to flow through the multi-layer filter screen, which can be used to further filter out the tiny water mist or oil droplets that were not centrifugally separated, ensuring deep separation of water and gas.

[0094] In some embodiments, the two ends of the separation device 303 are respectively sealed to the second air inlet 301 and the second air outlet 302 through flange interfaces. This ensures the sealing of the gas flow path, avoids the problem of untreated gas leakage, and facilitates the disassembly and maintenance of the filter or guide plate in the later stage. It also effectively prevents moisture from entering the vehicle's gas equipment with the gas, fundamentally reducing the problem of equipment corrosion.

[0095] Below, in conjunction with Figure 8 The ventilation duct and separator are explained through specific examples.

[0096] Figure 8 For a structural schematic diagram of the ventilation duct and separator provided in the embodiments of this application, please refer to [link / reference]. Figure 8 It includes a ventilation cooling pipe 200, a separator 300 and a separation device 303, wherein the ventilation cooling pipe 200 includes a first air inlet 201 and a first air outlet 202, and the separator 300 includes a second air inlet 301 and a second air outlet 302.

[0097] The gas dehumidification device 10 also includes a humidity detection device 600, which is located at the second air outlet 302 of the separator 300. The humidity detection device 600 is used to detect the humidity of the oil-water separated gas output from the second air outlet 302.

[0098] In some embodiments, the humidity detection device 600 can be a high-precision humidity sensor, and convert the detected humidity data into an electrical signal output.

[0099] In some embodiments, the humidity detection device 600 may include a detection probe. Specifically, the humidity detection device 600 can be fixed to the inner wall of the second air outlet 302 of the separator 300 by an embedded installation method, and its detection probe is in direct contact with the gas processed by the separator 303. This can ensure that the detection data can truly reflect the humidity status of the output gas.

[0100] The gas dehumidification device 10 also includes a display device 700, which is connected to the housing 100 and is used to display the humidity detected by the humidity detection device 600.

[0101] In some embodiments, the display device 700 is connected to the side of the housing 100 via a bracket.

[0102] In some embodiments, the display device 700 is also used to display the temperature of the coolant in the housing 100. Specifically, a temperature sensor is provided in the housing 100 to detect the temperature of the coolant.

[0103] In some embodiments, the display device 700 can be connected to the humidity detection device 600 and the temperature sensor in the enclosure 100 via wired or wireless means, respectively. The display device 700 can display humidity and temperature values ​​in real time in digital or graphical form. The display interface of the display device can be a partitioned display. For example, the left area of ​​the interface refreshes the coolant temperature (in °C) in real time in digital form, and the right area displays the gas water content, i.e., the humidity value (in %).

[0104] In some embodiments, the humidity detection device 600 continuously collects gas humidity information, the temperature sensor continuously collects the temperature of the coolant in the housing 100, and displays the humidity and temperature through the display device 700. For example, the display panel can display "temperature 22.5°C" and "humidity 12.8%", where humidity is used to indicate the water content in the gas.

[0105] The gas dehumidification device 10 also includes a cooling device 800, which is connected to the housing 100.

[0106] The cooling device 800 is used to cool the coolant in the housing 100.

[0107] The cooling device 800 includes a refrigerator 801 and a cooling pipe 802. The refrigerator 801 is connected to the bottom of the frame 400, and the cooling pipe 802 is located inside the housing 100.

[0108] In some embodiments, the refrigeration unit 801 is disposed below the housing 100 and inside the cavity 401 of the frame 400. The bottom of the refrigeration unit 801 is fixedly connected to the second connecting plate 403. The output end of the refrigeration unit 801 is connected to the input port of the refrigeration pipe 802, and the output port of the refrigeration pipe 802 is connected to the input end of the refrigeration unit 801, forming a refrigeration cycle loop. In this way, the refrigerant in the refrigeration pipe 802 can circulate and absorb the heat of the coolant, thereby maintaining the coolant at a set low temperature working state.

[0109] In some embodiments, the refrigeration pipe 802 is used to cool the coolant in the housing 100. The refrigeration pipe 802 passes through the bottom surface of the housing 100 and is fixed to the inner bottom surface of the housing 100 by welding or other means. The weld between the refrigeration pipe 802 and the bottom surface of the housing 100 is treated with a sealing process to ensure that the coolant does not leak from the penetration point. Furthermore, the refrigeration pipe 802 is U-shaped, with two straight pipe sections distributed parallel to each other on both sides of the bottom of the housing 100, and an arc-shaped bend connecting to the end of the straight pipe section and close to the inner wall of the housing. This layout allows the pipe to evenly cover the bottom area of ​​the housing, avoiding uneven cooling of the coolant in some areas. The material of the refrigeration pipe 802 can be copper pipe to maximize the heat exchange area.

[0110] It should be noted that the number of U-bends, pipe diameter and arrangement spacing of the cooling pipes 802 can be flexibly adjusted according to the specific dimensions of the cabinet 100 and the cooling requirements, thereby optimizing the overall cooling performance and adaptability of the system.

[0111] In some embodiments, the cooling device 800 further includes a control device 900 for controlling the operation of the refrigeration unit. The control device 900 is fixedly connected to the side of the housing 100 via a bracket, and the control device 900 and the display device 700 are located on one side of the housing 100, while the separator 300 and the drain component 106 are located on the other side of the housing 100.

[0112] The cooling device 800 is specifically used to obtain the humidity detected by the humidity detection device 600. When the humidity is greater than or equal to the first threshold, the refrigeration unit 801 is started and refrigerant is transferred to the refrigeration pipe 802 to cool the coolant in the box. When the humidity is less than the first threshold, the refrigeration unit 801 is stopped.

[0113] The first threshold refers to the amount of water in the gas exceeding a minimum threshold. For example, a humidity of 10% is usually set as the first threshold.

[0114] In some embodiments, the cooling device 800 can also be adjusted according to the temperature. Specifically, the control device 900 in the cooling device 800 is also used to obtain the temperature detected by the temperature sensor in the housing 100. When the temperature is greater than or equal to the second threshold, the refrigeration unit 801 is controlled to start and refrigerant is transferred to the refrigeration pipe 802 to cool the coolant in the housing. When the temperature is less than the second threshold, the refrigeration unit 801 is controlled to stop.

[0115] The second threshold refers to the minimum temperature that the coolant in the enclosure exceeds; for example, the current room temperature is usually set as the second threshold.

[0116] In some embodiments, the control device 900 includes an operation panel with multiple buttons, such as temperature adjustment buttons, which can control the refrigeration unit 801 by adjusting the temperature adjustment buttons on the operation panel based on the temperature and humidity displayed on the display device 700.

[0117] In some embodiments, the control device 900 may also include an integrated alarm function (e.g., audible and visual alarm, remote signal prompt, etc.) to remind staff to perform inspection or maintenance when humidity or temperature is abnormal and cannot be restored to the set range in a timely manner, thereby enhancing the reliability and security of the system.

[0118] When the humidity detected by the humidity detection device 600 is less than the first threshold, the oil-water separated gas is input into the vehicle's gas-using equipment.

[0119] The working process of the gas dehumidification equipment is explained below:

[0120] Before dehumidifying the gas, the inside of the chamber needs to be filled with coolant through the inlet. The coolant level in the chamber should be higher than the height of the ventilation duct. During the dehumidification process, the air compressor, separator, and control device should be kept running. The air compressor compresses the air in the environment and delivers the gas through the pipeline to the first air inlet of the ventilation duct. The gas flows in the ventilation duct and exchanges heat with the coolant in the chamber through the pipe wall, which cools the gas in the ventilation duct rapidly and condenses water. Since the first air outlet of the ventilation duct is higher than the first air inlet, the gas flows upward in the pipe. The condensed water droplets fall back along the pipe wall under the push of the airflow and gravity, while the rest enter the second air inlet of the separator through the first air outlet. The separator separates the moisture in the gas through the separation device and outputs dry gas from the second air outlet of the separator.

[0121] Meanwhile, a humidity detection device installed at the end of the second air outlet monitors the humidity value of the gas in real time, and a temperature sensor installed inside the enclosure monitors the temperature value of the coolant in real time. The temperature and humidity signals are sent to the control device respectively. The control device judges based on the current temperature and humidity. If the humidity is greater than or equal to the first threshold, or the temperature is greater than or equal to the second threshold, the control device is adjusted to control the refrigerator to start, so as to cool the coolant inside the enclosure and improve the condensation and dehumidification efficiency. When the coolant reaches the set temperature, the refrigerator is controlled to stop working, so as to ensure that the temperature inside the enclosure is controlled within the set range.

[0122] Once the temperature and humidity values ​​on the display device are confirmed to be within the set range, it indicates that the gas meets the gas requirements for the air filling operation, and the gas is then delivered to the vehicle's air-using equipment through the second air outlet of the separator.

[0123] The gas dehumidification equipment provided in this application includes a housing, a ventilation cooling pipe, a separator, a humidity detection device, a display device, and a cooling device. The ventilation cooling pipe is located inside the housing and immersed in coolant. The separator is located outside the housing, and its second air inlet is connected to the first air outlet of the ventilation cooling pipe. The humidity detection device is located at the second air outlet of the separator. The display device is connected to the housing and communicates with the humidity detection device. The cooling device is connected to the housing, and its cooling pipe is located inside the housing. The refrigeration unit is connected to the bottom of the frame. The cooling device can acquire signals from the humidity detection device and control the operation of the refrigeration unit. In the above structure, the uniformity of air cooling is increased by incorporating ventilation and cooling pipes inside the housing, and the water bath area is increased by using a reciprocating curved path to fully remove heat from the gas and complete the condensation process. Furthermore, an external separator separates the gas into oil and water to obtain dry gas. The combined design of the refrigeration unit, refrigeration pipes, and control device constitutes an adjustable intelligent cooling device, enabling temperature control within the housing. An integrated high-precision temperature and humidity sensor forms a dew point tracking control device, which monitors the temperature and humidity of the air source in real time, preventing dew point formation and ensuring that only qualified gas enters the vehicle equipment. In addition, compared with traditional treatment methods, this gas dehumidification equipment achieves closed-loop management from moisture separation and humidity monitoring to cooling regulation, eliminating the need for manual judgment and operation. It can accurately control the gas humidity to meet the dryness requirements of vehicle air-using equipment, reduce equipment corrosion caused by moisture, improve the reliability and automation of gas dehumidification, and reduce labor costs.
