Description

Technical Field

[0001] This invention relates to the field of geothermal fluid water vapor separation technology, and in particular to a device and method for separating water vapor from high-temperature geothermal fluid samples from geothermal wells. Background Technology

[0002] Geothermal wells are specially drilled deep wells used to extract geothermal resources from deep within the earth. These resources can be hot water or steam, and are mainly used for heating, hot spring baths, industrial applications, and power generation. During the extraction process, geothermal wells generate a large amount of high-temperature steam and associated gases that have a certain degree of pollution.

[0003] Patent publication number CN219953312U discloses a water vapor separation device for high-temperature geothermal fluid samples from a geothermal well, comprising a tank, a condensation assembly, a filter assembly, and a geothermal exchange device connected to the tank. The tank has an inlet pipe, the filter assembly is housed within the inlet pipe, and the condensation assembly is installed inside the tank. The tank is connected to a drain pipe and a reinjection pipe, and the tank is connected to the geothermal exchange device via the drain pipe. The geothermal exchange device has a tailwater pipe, which passes through the tank and connects to the condensation assembly. An outlet pipe is located at the top of the tank, with one end connected to a gas storage tank. In practical use, the condensation assembly condenses water vapor, and by using geothermal tailwater as condensate to exchange heat with water vapor, the recycling of thermal energy is further improved. This allows the geothermal tailwater to reheat during reinjection, reducing the impact of reinjection on geothermal energy storage and promoting the sustainable development of geothermal wells.

[0004] In the above-mentioned devices, the separated gas is input into a gas storage tank for storage during water vapor separation. However, the structure of the gas storage tank is relatively simple. Since the separated gas is polluting and cannot be directly discharged, the gas storage tank can only be vented after the separation operation is stopped if the gas storage tank is not connected to external treatment equipment. This is not convenient to operate and also results in low processing efficiency. In existing water vapor separation technologies, the gas storage tank cannot be disassembled, the condensation efficiency depends on the tailwater heat exchange, and the impurity cleaning is inconvenient. Therefore, a water vapor separation device for high-temperature geothermal fluid samples from geothermal wells is proposed to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a water vapor separation device for high-temperature geothermal fluid samples from geothermal wells.

[0006] The water vapor separation device for high-temperature geothermal fluid samples from geothermal wells provided by this invention adopts the following technical solution: A water vapor separation device for high-temperature geothermal fluid samples from a geothermal well includes a shell and a base plate. The base plate is located on one side of the shell. A feed pipe is fixedly connected to the front of the shell. A box is fixedly connected to the top of the shell. A gas driving device is fixedly connected inside the box. A gas collection mechanism is provided on the top of the base plate. The gas collection mechanism includes a detachable gas storage unit, which is located on the top of the base plate. Both ends of the detachable gas storage unit are fixedly connected to a connector pipe, and a valve is installed on the connector pipe. A vertical plate is fixedly connected to the top of the base plate, and the vertical plates are arranged at equal intervals on the top of the base plate. A connector pipe is installed on the vertical plate, and the connector pipe passes through the vertical plate and is fixedly connected to the vertical plate. An exhaust pipe is fixedly connected to the top of the housing, and one end of the exhaust pipe is fixedly connected to one end of one of the connector pipes. The connector pipe extends into the interior of the connector pipe and matches the connector pipe.

[0007] By adopting the above technical solution, after the geothermal fluid inside the shell is separated by water vapor, the separated gas enters the detachable gas storage unit. The detachable gas storage unit at the very end will inflate first. When the outermost detachable gas storage unit inflates to its maximum value, the valve of the adjacent detachable gas storage unit facing this detachable gas storage unit can be closed, and the outermost detachable gas storage unit can be removed and replaced. During the replacement process, there is no need to shut down the overall separation operation of the device, and the remaining detachable gas storage units can continue to store gas, ensuring separation efficiency. Moreover, since the detachable gas storage units are relatively lightweight, it is easier for workers to carry them.

[0008] Preferably, a plug plate is fixedly connected to the plug tube, and an annular plate is integrally formed on the outside of the connector tube, with the plug plate penetrating through the annular plate.

[0009] By adopting the above technical solution, the insert plate is installed after penetrating the annular plate.

[0010] Preferably, a locking block is slidably connected inside the insert plate, the locking block extends out of the insert plate, the locking block is in contact with one side of the annular plate, and a spring is fixedly connected inside the insert plate, the spring being fixedly connected to the locking block.

[0011] By adopting the above technical solution, after the insert plate penetrates the annular plate, the elastic force of the spring will push the locking block out of the insert plate, thus completing the fixed installation between the connector tube and the insert tube.

[0012] Preferably, the housing is provided with a separation mechanism, which includes a bottom condensing plate and an upper condensing plate. The bottom condensing plate and the upper condensing plate both penetrate the same side wall of the housing and are fixedly connected to the housing. A middle condensing plate is provided between the bottom condensing plate and the upper condensing plate. The middle condensing plate penetrates the other side wall of the housing and is fixedly connected to the housing. An auxiliary frame is fixedly connected to one side wall of the inner cavity of the housing. A bottom liquid inlet is provided on the auxiliary frame. A drain pipe is fixedly connected to one side of the auxiliary frame. The drain pipe extends out of the housing and is fixedly connected to the housing. An installation frame is fixedly connected to the top of the housing. A gas dispersing mechanism is fixedly connected inside the installation frame.

[0013] By adopting the above technical solution, water vapor is condensed when it passes through the bottom condenser plate, the middle condenser plate and the upper condenser plate, and the condensed liquid falls downwards into the auxiliary frame for collection.

[0014] Preferably, the top of the upper condenser plate, the middle condenser plate and the bottom condenser plate are all provided with liquid collection tanks, which are located inside the shell. The top of the bottom condenser plate is also provided with a converging tank, which is connected to the liquid collection tank. A drain heat conduction pipe is fixedly connected to the bottom of the bottom condenser plate.

[0015] By adopting the above technical solution, the condensed geothermal tailwater flows down through the collection tank and finally converges in the collection tank on the bottom condensing plate. It is then discharged through the drain heat conduction pipe. The drain heat conduction pipe can conduct heat, meaning that when external geothermal fluid continues to enter, the heat will be absorbed by the drain heat conduction pipe, thereby heating the condensed liquid to a certain extent. This allows the geothermal tailwater to reheat during the reinjection process, reducing the impact of the reinjection process on geothermal energy storage.

[0016] Preferably, the drain heat pipes are arranged at equal intervals on the bottom condenser plate, one end of each drain heat pipe is fixedly connected to one side of the auxiliary frame, and the drain heat pipes are respectively connected to the collecting tank and the inner cavity of the auxiliary frame.

[0017] By adopting the above technical solution, multiple drain heat pipes can be installed to divert geothermal tailwater, allowing it to be heated more effectively.

[0018] Preferably, an air intake frame is fixedly connected to one end of the upper condenser plate, the middle condenser plate, and the bottom condenser plate. An air-cooling cavity is opened inside the upper condenser plate, the middle condenser plate, and the bottom condenser plate. The air intake frame is located on one side of the air intake end of the air-cooling cavity and is connected to the air-cooling cavity. Two connecting pipes are fixedly connected to the top of the mounting frame, and the exhaust ends of the two connecting pipes are fixedly connected to the three air intake frames respectively.

[0019] By adopting the above technical solution and setting up an air-cooled cavity, gas can flow inside the air-cooled cavity, and during the flow, the upper condenser plate, middle condenser plate and bottom condenser plate are cooled by air, so as to improve their condensation efficiency of water vapor.

[0020] Preferably, a filter frame is fixedly connected to one end of the feed pipe, an external pipe is fixedly connected to the front side wall of the filter frame, a filter assembly is provided on the filter frame, the filter assembly includes a filter screen, a scraper is provided on the front side of the filter screen, a control plate is provided at the bottom of the filter frame, the control plate penetrates the bottom wall of the filter frame, a connecting plate is integrally formed between the control plate and the scraper, the scraper is in contact with the front side of the filter screen, and a frame plate is fixedly connected to the bottom of the filter frame.

[0021] By adopting the above technical solution, the geothermal fluid will be filtered in the filter frame before entering the shell. The filtered impurities remain on the filter screen and can be scraped off by pulling down the scraper.

[0022] Preferably, a positioning plate is slidably connected to the inner side of the frame plate, the positioning plate extends into the control plate, and a threaded adjusting rod is rotatably connected to one side of the positioning plate, the threaded adjusting rod extends out of the frame plate and is threadedly connected to the frame plate.

[0023] By adopting the above technical solution, after rotating the threaded adjusting rod, the threaded adjusting rod drives the positioning plate to move horizontally. After the positioning plate is inserted into the control plate, it limits the position of the control plate.

[0024] Another technical problem to be solved by the present invention is to provide a separation method for a water vapor separation device for high-temperature geothermal fluid samples from a geothermal well, comprising the following steps: S1, Front-end Filtering Before the geothermal fluid sample enters the shell, it first enters the filter frame, where the filter screen filters out impurities in the fluid. When the scraper is pulled down, the impurities on the filter screen can be cleaned out to the outside of the shell. S2, Water vapor separation Liquid fluid entering the shell will accumulate at the bottom of the shell and enter the auxiliary frame through the bottom liquid inlet of the auxiliary frame, while unseparated water vapor will flow upward, be condensed by the upper condenser plate, middle condenser plate and bottom condenser plate, slide down and also enter the auxiliary frame, and finally be discharged, while gas enters the exhaust pipe. S3, Gas Collection The separated gas enters the detachable gas storage unit through the exhaust pipe. The detachable gas storage unit expands after the gas enters, thereby collecting and storing the gas. During the collection process, the detachable gas storage unit furthest from the shell will expand to its maximum value first. After reaching the maximum value, while ensuring the continued operation of the device, the outermost detachable gas storage unit can be removed and replaced individually.

[0025] In summary, the present invention has the following beneficial technical effects: 1. A water vapor separation device and method for high-temperature geothermal fluid samples from geothermal wells: Through the design of the gas collection mechanism, after the geothermal fluid inside the shell is separated into water vapor, the separated gas enters a detachable gas storage unit. The detachable gas storage unit at the very end will inflate first. When the outermost detachable gas storage unit inflates to its maximum value, the valve of the adjacent detachable gas storage unit facing this detachable gas storage unit can be closed, and the outermost detachable gas storage unit can be removed and replaced. During the replacement process, it is not necessary to shut down the overall separation operation of the device, and the remaining detachable gas storage units can continue to store gas, ensuring separation efficiency. Moreover, because the detachable gas storage units are relatively lightweight, the modular gas collection structure that allows for replacement without shutting down the machine makes operation more labor-saving and efficient.

[0026] 2. A water vapor separation device and method for high-temperature geothermal fluid samples from geothermal wells: Through the design of the separation mechanism, the gas dispersing mechanism blows the airflow into the connecting pipe after it works. Through a multi-stage condensation method that combines air cooling and thermal conduction coupling, the upper condensing plate, middle condensing plate, and bottom condensing plate are rapidly cooled by air cooling, which can effectively ensure cooling efficiency and cooling quality. When the condensed geothermal tailwater enters the drain heat pipe, the heat from the geothermal fluid entering from the outside heats the drain heat pipe, so that the geothermal tailwater can be reheated during the reinjection process, reducing the impact of the reinjection process on geothermal energy storage.

[0027] 3. A water vapor separation device and method for high-temperature geothermal fluid samples from geothermal wells: Through the design of the filter components, the filter screen in the filter frame filters impurities in the fluid. The filtered impurities remain on the filter screen. If too many impurities accumulate, in order to ensure the permeability of the filter screen, the scraper can be pulled down. During the downward movement of the scraper, the impurities on the filter screen are scraped off. Thus, through the design of the clean filter frame, the filtration quality of the filter screen can be effectively guaranteed. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 11 The present invention will be described in further detail below.

[0031] This invention discloses a water vapor separation device for high-temperature geothermal fluid samples from geothermal wells. (Refer to...) Figures 1-11The device includes a housing 1 and a base plate 2. The base plate 2 is located on one side of the housing 1. A feed pipe 3 is fixedly connected to the front of the housing 1. A box body 4 is fixedly connected to the top of the housing 1. A gas driving device 5 is fixedly connected inside the box body 4. The gas driving device 5 can be a blower. A gas collecting mechanism 6 is provided on the top of the base plate 2. The gas collecting mechanism 6 includes a detachable gas storage unit 61. The detachable gas storage unit 61 can be in the form of a rubber air bag. The detachable gas storage unit 61 is located on the top of the base plate 2. Both ends of the detachable gas storage unit 61 are fixedly connected to a connector 62. A valve 63 is provided on the connector 62. A vertical plate 64 is fixedly connected to the top of the base plate 2. Vertical plates 64 are arranged at equal intervals on the top of the base plate 2. Connector pipes 65 are installed on the vertical plates 64, passing through and being fixedly connected to them. An exhaust pipe 66 is fixedly connected to the top of the housing 4, with one end of the exhaust pipe 66 fixedly connected to one end of one of the connector pipes 65. A connecting pipe 62 extends into the connector pipe 65 and matches it. After the geothermal fluid inside the housing 1 is separated by water vapor, the separated gas enters the removable gas storage unit 61. The removable gas storage unit 61 is located at the very end of the housing. The gas storage unit 61 will inflate first. After the outermost detachable gas storage unit 61 inflates to its maximum value, the valve 63 of the adjacent detachable gas storage unit 61 facing this detachable gas storage unit 61 can be closed. Then, the outermost detachable gas storage unit 61 can be removed and replaced. During the replacement process, there is no need to shut down the overall separation operation of the device. The remaining detachable gas storage units 61 can continue to store gas, ensuring separation efficiency. Moreover, since the detachable gas storage unit 61 is relatively lightweight, it is easier for staff to carry it.

[0032] A plug plate 67 is fixedly connected to the plug tube 62. An annular plate 68 is integrally formed on the outside of the connector tube 65. The plug plate 67 passes through the annular plate 68 and is installed after passing through the annular plate 68. A locking block 69 is slidably connected inside the plug plate 67. The locking block 69 extends out of the plug plate 67 and fits against one side of the annular plate 68. A spring 691 is fixedly connected inside the plug plate 67. The spring 691 is fixedly connected to the locking block 69. When the plug plate 67 passes through the annular plate 68, the elastic force of the spring 691 pushes the locking block 69 out of the plug plate 67, completing the fixed installation between the connector tube 65 and the plug tube 62.

[0033] A separation mechanism 7 is provided on the shell 1. The separation mechanism 7 includes a bottom condenser plate 71 and an upper condenser plate 72. The bottom condenser plate 71 and the upper condenser plate 72 both penetrate the same side wall of the shell 1 and are fixedly connected to the shell 1. A middle condenser plate 73 is provided between the bottom condenser plate 71 and the upper condenser plate 72. The middle condenser plate 73 penetrates the other side wall of the shell 1 and is fixedly connected to the shell 1. An auxiliary frame 74 is fixedly connected to one side wall of the inner cavity of the shell 1. A bottom liquid inlet is provided on the auxiliary frame 74. A drain pipe 75 is fixedly connected to one side of the auxiliary frame 74. The drain pipe 75 extends out of the shell 1 and is fixedly connected to the shell 1. An installation frame 76 is fixedly connected to the top of the shell 1. A gas dispersing mechanism 77 is fixedly connected inside the installation frame 76. The gas dispersing mechanism 77 can be in the form of a fan. Water vapor is condensed when it passes through the bottom condenser plate 71, the middle condenser plate 73 and the upper condenser plate 72. The condensed liquid falls downward and is collected in the auxiliary frame 74. The top of the upper condensing plate 72, the middle condensing plate 73, and the bottom condensing plate 71 are all provided with liquid collection tanks 78, which are located inside the shell 1. The top of the bottom condensing plate 71 is also provided with a converging tank 79, which is connected to the liquid collection tank 78. The bottom of the bottom condensing plate 71 is fixedly connected with a drain heat conduction pipe 791. The condensed geothermal tailwater liquid slides down through the liquid collection tank 78 and is finally collected in the converging tank 79 on the bottom condensing plate 71. Finally, it is discharged through the drain heat conduction pipe 791. The drain heat conduction pipe 791 can conduct heat. That is, when the external geothermal fluid continues to enter, the heat will be absorbed by the drain heat conduction pipe 791, thereby heating the condensed liquid to a certain extent, so that the geothermal tailwater can be reheated during the reinjection process, reducing the impact of the reinjection process on geothermal energy storage. The drain heat pipes 791 are arranged at equal intervals on the bottom condenser plate 71. One end of each drain heat pipe 791 is fixedly connected to one side of the auxiliary frame 74. The drain heat pipes 791 are connected to the collecting tank 79 and the inner cavity of the auxiliary frame 74, respectively. The multiple drain heat pipes 791 can divert the geothermal tailwater, allowing it to be heated better. One end of each of the upper condenser plate 72, middle condenser plate 73, and bottom condenser plate 71 is fixedly connected to an air inlet frame 792. The interiors of the upper condenser plate 72, middle condenser plate 73, and bottom condenser plate 71 are all... An air-cooled cavity 793 is provided, and an air intake frame 792 is located on one side of the air intake end of the air-cooled cavity 793 and is connected to the air-cooled cavity 793. Two connecting pipes 794 are fixedly connected to the top of the mounting frame 76, and the exhaust ends of the two connecting pipes 794 are fixedly connected to the three air intake frames 792 respectively. By setting up the air-cooled cavity 793, the gas can flow inside the air-cooled cavity 793, and during the flow, the upper condenser plate 72, the middle condenser plate 73 and the bottom condenser plate 71 are cooled by air to improve their condensation efficiency of water vapor.

[0034] A filter frame 8 is fixedly connected to one end of the feed pipe 3. An external pipe is fixedly connected to the front wall of the filter frame 8. A filter assembly 9 is provided on the filter frame 8. The filter assembly 9 includes a filter screen 91. A scraper 92 is provided on the front side of the filter screen 91. A control plate 93 is provided at the bottom of the filter frame 8. The control plate 93 penetrates the bottom wall of the filter frame 8. A connecting plate 94 is integrally formed between the control plate 93 and the scraper 92. The scraper 92 is attached to the front side of the filter screen 91. A frame plate 95 is fixedly connected to the bottom of the filter frame 8. When the geothermal fluid enters the interior of the shell 1, it will enter the filter frame 8 before being filtered. The filtered impurities remain on the filter screen 91. The impurities on the filter screen 91 can be scraped off by pulling down the scraper 92. A positioning plate 96 is slidably connected to the inner side of the frame plate 95. The positioning plate 96 extends into the control plate 93. A threaded adjusting rod 97 is rotatably connected to one side of the positioning plate 96. The threaded adjusting rod 97 extends out of the frame plate 95 and is threadedly connected to the frame plate 95. After rotating the threaded adjusting rod 97, the threaded adjusting rod 97 drives the positioning plate 96 to move horizontally. After the positioning plate 96 is inserted into the control plate 93, it limits the position of the control plate 93.

[0035] I. Applicable fluid temperature range Key features: The device is equipped with a three-stage condensation structure consisting of a bottom condensing plate, a middle condensing plate, and an upper condensing plate. The condensing plates have an internal air-cooling cavity, which drives the airflow to force cooling. At the same time, the drain heat pipe can heat the condensed geothermal tailwater, reducing the impact of reinjection on geothermal energy storage.

[0036] Scope of Application Inference: Based on the naming of "high-temperature geothermal fluid" and the enhanced design of the condensation system, this device is mainly designed for medium-to-high temperature geothermal fluids (the fluid temperature extracted from conventional geothermal wells is mostly 100-350℃, and the device's applicable temperature range is estimated to be approximately 100-300℃). If the fluid temperature is too high (such as dry steam exceeding 350℃), the high-temperature resistance limit of the condenser plate material needs to be additionally evaluated; if the temperature is below 100℃ (such as low-temperature geothermal water), the device can still be used, but the condensation efficiency may exceed actual requirements.

[0037] Limitations: The cooling capacity of the condenser plate must match the initial temperature of the fluid. If the temperature is too high, it is necessary to ensure that the airflow rate of the air-cooling cavity is compatible with the high-temperature resistance of the condenser plate material (such as metal alloy).

[0038] II. Pressure Level Applicable Pressure: Based on the routine requirements of geothermal fluid sample collection (non-industrial high-pressure mining scenarios), the applicable fluid pressure for the device is approximately atmospheric pressure to 1.0 MPa (low to medium-low pressure range). If the fluid pressure exceeds 1.0 MPa, the pressure resistance of the rubber airbag and the strength of the pipeline connections need to be further strengthened; otherwise, there may be a risk of leakage.

[0039] Pressure limitations of key components: The maximum pressure that the rubber airbag can withstand needs to be matched with the device design. Typically, the upper limit of pressure that the rubber airbag can withstand in low-pressure scenarios is about 0.5-1.0MPa. The specific parameters should be referred to the parameters of the rubber material actually selected.

[0040] III. Rubber airbag volume Design Features The rubber airbag is a "detachable unit" with both ends connected to the connector tube via insert tubes, allowing for individual replacement. The vertical plates on the base plate are arranged at equal intervals, and the number of rubber airbags can be increased or decreased as needed to achieve flexible volume adjustment.

[0041] Volume estimation: Based on the intermittent, small-batch characteristics of water vapor separation in geothermal fluid samples (sample collection rather than continuous industrial gas production), the estimated volume of a single rubber gasbag is 0.1-1.0 m³ (the volume range of a typical small gas storage unit). If it is necessary to increase the total gas storage capacity, it can be achieved by increasing the number of vertical plates and connecting multiple rubber gasbags in series (e.g., connecting five 1.0 m³ gasbags in series can achieve a total volume of 5.0 m³).

[0042] Influencing factors: The volume of the airbag needs to be matched with the separation efficiency of the device. For example, if the device separates 0.5 m³ of gas per hour, a single 1.0 m³ airbag can meet the continuous gas storage requirements for 2 hours, avoiding frequent replacements.

[0043] IV. Corrosion-resistant materials Shell and base plate: High-temperature geothermal fluid, water vapor, and associated gases; stainless steel (e.g., 304, 316L). Geothermal fluid may contain corrosive ions such as chloride ions and sulfides. Stainless steel has good corrosion resistance and high-temperature resistance, meeting the structural strength requirements of the device shell. Condensation plate (bottom / middle / top): High-temperature water vapor and condensate; copper alloy (e.g., brass) or stainless steel. The condensation plate needs to balance thermal conductivity and corrosion resistance. Copper alloy has high thermal conductivity, while stainless steel has stronger corrosion resistance. The choice can be made according to the corrosiveness of the fluid. The document mentions that the condensation plate has a "liquid collection tank" and "gathering tank," which need to avoid liquid accumulation corrosion. Rubber gasbag: Separated associated gases (containing polluting components); chemically resistant rubber (e.g., nitrile rubber, fluororubber). | The associated gases may contain corrosive gases such as hydrogen sulfide and carbon dioxide. Nitrile rubber has good oil resistance and chemical resistance, while fluororubber has stronger corrosion resistance. The choice can be made according to the gas composition. Material selection logic: The corrosion-resistant materials of the device need to balance "high temperature resistance" and "media corrosion resistance". For example, metal alloys (stainless steel, copper alloys) are preferred for high temperature fluid channels (such as condenser plates and exhaust pipes), while special rubbers that are resistant to chemical corrosion are selected for flexible components such as rubber airbags to ensure service life in high temperature and corrosive environments.

[0044] Another technical problem to be solved by the present invention is to provide a separation method for a water vapor separation device for high-temperature geothermal fluid samples from a geothermal well, comprising the following steps: S1, Front-end Filtering Before the geothermal fluid sample enters the shell 1, it first enters the filter frame 8, where the filter screen 91 filters the impurities in the fluid. The filtered impurities remain on the filter screen 91. If too many impurities accumulate, in order to ensure the permeability of the filter screen 91, after the device is stopped, the threaded adjustment rod 97 can be rotated. After the threaded adjustment rod 97 rotates, it drives the positioning plate 96 to move horizontally to the side of the control plate 93. When the scraper 92 is pulled down, the scraper 92 scrapes the impurities on the filter screen 91 downwards during the downward movement, thus properly cleaning the filter screen 91 and effectively ensuring the filtration quality of the filter screen 91. S2, Water vapor separation Liquid entering the shell 1 accumulates at the bottom of the shell 1 and enters the auxiliary frame 74 through the bottom liquid inlet. Unseparated water vapor flows upward and is condensed by the upper condenser plate 72, the middle condenser plate 73 and the bottom condenser plate 71. The condensed liquid flows downward through the liquid collection tank 78 and finally slides down onto the bottom condenser plate 71. After landing on the bottom condenser plate 71, it enters the collection tank 79 and is discharged into the drain heat conduction pipe 791. Finally, it slides down and enters the auxiliary frame 74. The liquid in the auxiliary frame 74 is discharged to the outside through the drain pipe 75, while the separated gas enters the exhaust pipe 66. During the condensation process, the gas dispersing mechanism 77 blows air into the connecting pipe 794 after the upper condenser plate 72, middle condenser plate 73, and bottom condenser plate 71 are working. The air is then sent to the air intake frame 792 through the connecting pipe 794. After entering the air intake frame 792, the air enters through the air intake end of the air-cooling cavity 793, flows in the air-cooling cavity 793, and is discharged through the other end opening of the air-cooling cavity 793. This achieves rapid air cooling of the upper condenser plate 72, middle condenser plate 73, and bottom condenser plate 71, effectively ensuring the cooling efficiency and cooling quality of the upper condenser plate 72, middle condenser plate 73, and bottom condenser plate 71. S3, Gas Collection After the gas-driven device 5 operates, it draws in the separated gas. The drawn-in gas enters the removable gas storage unit 61 through the exhaust pipe 66. The removable gas storage unit 61 expands after the gas enters, thereby collecting and storing the gas. During the collection process, the removable gas storage unit 61 furthest from the housing 1 will expand to its maximum value first. When the outermost removable gas storage unit 61 needs to be replaced, the valve 63 at the end of the adjacent removable gas storage unit 61 facing this removable gas storage unit 61 is closed, and the valves at both ends of this removable gas storage unit 61 are also closed. After 63 is closed, squeeze the latch 69 on the detachable gas storage unit 61 and push the latch 69 into the insert plate 67. The insert plate 67 can be quickly pulled out from the annular plate 68.
