Description

Technical Field

[0001] This utility model relates to the field of gas separation technology, specifically a high-pressure gas separation device. Background Technology

[0002] High-pressure gas separation is a technical process that uses physical or chemical methods to separate components of a gas mixture under high pressure. This technology is commonly used in industrial fields, such as air separation to obtain oxygen and nitrogen, natural gas processing, and the petrochemical industry. In these applications, applying pressure conditions higher than atmospheric pressure can promote the liquefaction or adsorption of certain gas components, thereby separating them from other gas components.

[0003] However, in existing technologies, long-term high-pressure operation may lead to material fatigue, especially when exposed to corrosive gases (such as H2S and CO2), where corrosion problems are exacerbated, making subsequent replacement of adsorbents, membrane materials, or chemical reagents difficult. Therefore, we provide a high-pressure gas separation device. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure gas separation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure gas separation device, comprising a processing tank, a tank cover on the top of the processing tank, limit sliders on both sides of the inner wall of the processing tank, a breathable mesh in the slots opened on opposite sides of the two limit sliders, a cover plate on the top of the two limit sliders, an adsorbent at the bottom of the two cover plates, two adsorption membranes inside the processing tank, two connecting rods between the two adsorption membranes, sliding grooves on both sides of the two adsorption membranes, a handle on the top side of the adsorption membrane at the bottom of the tank cover, and a fixing structure on the outside of the tank cover.

[0006] As a further preferred embodiment of this technical solution, the fixing mechanism includes a sealing mounting ring, and the outer side of the tank cover and the outer side of the top of the processing tank are both fixedly connected with the sealing mounting ring.

[0007] As a further preferred embodiment of this technical solution, the two sealing rings are fixedly installed together by bolts, and an air inlet is provided on one side of the top of the can lid.

[0008] As a further preferred embodiment of this technical solution, limit sliders are fixedly connected to both sides of the inner wall of the processing box, and a breathable mesh is fixedly connected to a slot opened on one side of the limit slider.

[0009] As a further preferred embodiment of this technical solution, an adsorbent is fixedly installed at the bottom of the cover plate, and the adsorbent is connected to the slot opened in the limiting slider.

[0010] As a further preferred embodiment of this technical solution, the limiting slider is slidably connected to the inner wall of the groove, and two connecting rods are fixedly connected between the two adsorption membranes.

[0012] This utility model provides a high-pressure gas separation device, which has the following beneficial effects:

[0013] (1) This utility model compresses the gas to the bottom of the treatment tank by starting a high-pressure pump. The gas will pass through two sets of adsorption membranes. The first set of membranes initially intercepts large molecular impurities (such as dust and moisture) to reduce the load on subsequent membrane layers. The second set of membranes further selectively adsorbs the target gas to improve the separation purity. The two sets of membranes are designed in series or in parallel to share the high pressure impact to extend the service life, reduce cross-contamination, and finally output high-purity gas and reduce maintenance costs. The adsorption membrane can be removed from the treatment tank by the provided limiting slider and groove. In addition, the adsorbent is placed on the inner wall of the slider and the gas odor in the treatment tank can be adsorbed by the breathable mesh.

[0014] (2) The present invention can fix the tank cover and the treatment tank by means of the sealing installation ring and bolt. The sealing installation ring is made of rubber and is used to fill the gap between the tank cover and the tank body to prevent gas or liquid leakage, ensure stable pressure inside the treatment tank, and avoid media leakage or external pollutants entering.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1-5 As shown, in this embodiment, a high-pressure gas separation device includes a processing tank 11. A tank cover 12 is provided on the top of the processing tank 11. Limiting sliders 13 are provided on both sides of the inner wall of the processing tank. A permeable mesh 14 is provided in a slot on one side of each limiting slider 13. Limiting sliders 13 are fixedly connected to both sides of the inner wall of the processing tank. A permeable mesh 14 is fixedly connected in a slot on one side of each limiting slider 13. A cover plate 15 is provided on the top of each limiting slider 13. An adsorbent 16 is provided at the bottom of each cover plate 15. The adsorbent 16 is fixedly installed at the bottom of each cover plate 15. The adsorbent 16... The treatment tank 11 is installed in the slot of the limiting slider 13. The inside of the treatment tank 11 is provided with two adsorption membranes 17. Two connecting rods 18 are provided between the two adsorption membranes 17. The two adsorption membranes 17 are provided with sliding grooves 19 on both sides. The limiting slider 13 is slidably connected to the inner wall of the sliding grooves 19. The two connecting rods 18 are fixedly connected between the two adsorption membranes 17. The top side of the adsorption membrane 17 at the bottom of the tank cover 12 is provided with a handle 110. The bottom side of the adsorption membrane 17 at the bottom of the tank cover 12 is fixedly connected with a handle 110. The bottom sides of the treatment tank 11 are provided with air outlets 31. The outside of the tank cover 12 is provided with a fixing structure.

[0025] In this embodiment, when the device is needed to separate gases, the gas can be injected into the processing tank 11 through the inlet 23. The high-pressure pump 24 is started to compress the gas to the bottom of the processing tank 11. The gas will pass through two sets of adsorption membranes 17. The first set of membranes initially intercepts large molecular impurities such as dust and moisture, reducing the load on subsequent membrane layers. The second set of membranes further selectively adsorbs target gases such as CO2 and O2, improving the separation purity. The two sets of membranes are designed in series or parallel to share the high-pressure impact to extend their lifespan, and to ensure continuous regeneration through alternating regeneration such as pressure swing adsorption. The system operates while reducing cross-contamination, ultimately outputting high-purity gas and reducing maintenance costs. When the two adsorption membranes 17 need to be disassembled and cleaned, since the two adsorption membranes 17 are connected by the connecting rod 18, the handle 110 provided on the upper left adsorption membrane 17 can be pulled up to lift the two adsorption membranes 17. The slide groove 19 will slide on the limiting slider 13, which can ensure the stability of the adsorption membrane 17 when it is removed or installed. In addition, the adsorbent 16 is placed on the inner wall of the slider, and the gas odor in the treatment tank 11 can be adsorbed through the breathable net 14.

[0026] like Figures 1-5 As shown, the fixing mechanism 2 includes a sealing mounting ring 21. The outer side of the tank cover 12 and the outer side of the top of the treatment tank 11 are both fixedly connected with the sealing mounting ring 21. The two sealing mounting rings 21 are fixedly installed together by bolts 22. An air inlet 23 is opened on one side of the top of the tank cover 12.

[0027] In this embodiment, the can lid 12 and the treatment tank 11 can be fixedly installed by the sealing installation ring 21 and the bolt 22. The sealing installation ring 21 is made of rubber and is used to fill the gap between the can lid 12 and the tank body to prevent gas or liquid leakage, ensure stable pressure inside the treatment tank 11, and prevent media leakage or external pollutants from entering.

[0028] This utility model provides a high-pressure gas separation device, the specific working principle of which is as follows:

[0029] When the device is used for gas separation, the gas is injected into the treatment tank 11 through the inlet 23, compressed to the bottom of the tank by the high-pressure pump 24, and then passes through two sets of adsorption membranes 17 in sequence. The first set of membranes is responsible for intercepting large molecular impurities such as dust and moisture, reducing the load on subsequent membrane layers; the second set of membranes specifically adsorbs target gases such as CO2 and O2, improving separation purity. The two sets of membranes are designed in series or parallel to balance the high-pressure impact to extend their lifespan, and achieve continuous operation through alternating regeneration such as pressure swing adsorption, reducing cross-contamination, and ultimately outputting high-purity gas and reducing maintenance costs. When disassembly and cleaning are required, since the two sets of adsorption membranes 17 are linked by the connecting rod 18, the two membrane components can be lifted simultaneously by simply pulling the handle 110 of the upper left membrane. The cooperation between the slide 19 and the limiting slider 13 ensures that the removal or installation process is smooth and controllable. In addition, the adsorbent 16 filled in the inner wall of the slider can adsorb odors in the treatment tank 11 through the breathable mesh 14, further optimizing the gas treatment effect.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
