[0017] Beneficial effects

[0018] This invention provides a device for recycling PSA-3 desorbed gas. Compared with the prior art, it has the following advantages:

[0019] 1. In this PSA-3 desorbed gas recycling device, a large amount of desorbed gas produced during production is first stored in a buffer tank. Starting the gas pump allows it to be introduced into the washing liquid in the treatment tank via the first conduit. Impurity particles become heavier upon contact with the liquid and are trapped inside the treatment tank. Activating the servo motor drives the rotating rod and stirring blades to rotate, causing the washing liquid to rotate and break up large bubbles, generating more small bubbles. This increases the contact area with the washing liquid and enhances the interception rate of tiny impurity particles.

[0020] 2. In this PSA-3 desorbed gas recycling device, the desorbed gas after washing and filtration enters a rectangular space temporarily stored and collected through the vent holes of the substrate. This space is formed by two horizontal partitions, a vertical partition, and the inner wall of the processing chamber. When the gas pressure reaches the required level, it enters the sleeve through the vent holes of the top cover, pushing the slider upward and compressing the spring until the slider is higher than one end of the second conduit. The gas then enters the filter through the second conduit for further filtration. The filtered desorbed gas is then introduced into the compressor for compression and finally transported to the production stage requiring the gas through multiple reuse pipes connected by the five-way pipe at the bottom of the compressor, thus completing the recycling process.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4 This application provides a PSA-3 desorbed gas recycling device, including a base 1, with an execution component 2 disposed on the top of the base 1. The execution component 2 includes a processing tank 24, which is fixedly connected to the top of the base 1. A top cover 25 is fixedly connected to the top of the processing tank 24. A base plate 26 is fixedly connected between the inner walls of the processing tank 24. A longitudinal partition 27 and a transverse partition 28 are fixedly connected to the top of the base plate 26. A buffer tank 21 is fixedly installed on the top of the base 1, and an air pump 22 is fixedly installed on the top of the buffer tank 21. A first conduit 23 is fixedly connected to the interface of the air pump 22, with one end of the first conduit 23 penetrating through the top cover 25 and the base plate 26. A washing liquid is filled between the base plate 26 and the inner bottom of the processing tank 24. A bracket 29 is fixedly connected between the two longitudinal partitions 27. A rotating rod 210 is rotatably connected inside the bracket 29. A stirring blade 212 is fixedly connected to the outer wall of one end of the rotating rod 210. A servo motor 211 is fixedly installed on the top of the top cover 25. The output shaft of the servo motor 211 is fixedly connected to one end of the rotating rod 210.

[0030] In practice: By storing a large amount of desorbed gas generated during production in a buffer tank 21, the desorbed gas inside the buffer tank 21 can be released by starting the air pump 22. This desorbed gas is introduced into the washing liquid in the processing tank 24 through the first conduit 23. Impurity particles that may be mixed with the desorbed gas will become heavier due to contact with the liquid and will be intercepted in the processing tank 24. By starting the servo motor 211, the rotating rod 210 can be driven to rotate, which in turn drives the stirring blade 212 to rotate, thereby causing the washing liquid inside the processing tank 24 to rotate and move, thereby breaking up the larger bubbles and generating more small bubbles, thus increasing the contact area with the washing liquid and enhancing the interception rate of small impurity particles.

[0031] ReferenceFigures 1 to 4 In one aspect of this embodiment, a sleeve 213 is fixedly connected to the top of the top cover 25, and a spring 221 is fixedly connected to the inner wall of the sleeve 213. A slider 222 is fixedly connected to one end of the spring 221, and the slider 222 is slidably connected to the inner wall of the sleeve 213. Two transverse partitions 28, one side of the longitudinal partition 27, and one side of the inner wall of the processing box 24 form a rectangular space. Ventilation holes are provided in the interior of the substrate 26 and the top cover 25 corresponding to the central area of ​​this space. An auxiliary rod 215 is fixedly connected to the top of the base 1. A first mounting bracket 216 and a second mounting bracket 218 are fixedly connected between the two auxiliary rods 215. A filter 219 is fixedly installed on the top of the first mounting bracket 216. A second conduit 214 is fixedly connected to the top of the filter 219. One end of the second conduit 214 communicates with the inside of the sleeve 213. A compressor 217 is fixedly connected to the top of the second mounting bracket 218. The compressor 217 and the filter 219 are connected through a connecting pipe. A five-way pipe 220 is fixedly installed at the bottom of the compressor 217.

[0032] In practice: the desorbed gas after being washed and filtered will enter the rectangular space enclosed by two horizontal partitions 28 and vertical partitions 27 and the inner wall of the processing box 24 through the vent on the substrate 26 for temporary storage and collection. When the gas pressure reaches a certain level, it will enter the sleeve 213 through the vent on the top cover 25, thereby pushing the slider 222 to move upward and compressing the spring 221. When the slider 222 is higher than the end of the second conduit 214, the gas will then enter the filter 219 for fine filtration through the second conduit 214. The finely filtered desorbed gas will be introduced into the compressor 217 for compression. Finally, the compressed desorbed gas will be transported to the production process that needs the gas through the five-way pipe 220 connected to the bottom of the compressor 217 and multiple reuse pipes, thereby completing the recycling of the desorbed gas.

[0033] All electrical devices in this plan are powered by an external power source.

[0034] Working principle: First, a large amount of desorbed gas generated during the production process is stored in buffer tank 21. After the air pump 22 is started, it can help release the desorbed gas inside the buffer tank 21. The desorbed gas is introduced into the washing liquid in the treatment tank 24 through the first conduit 23. During this process, impurity particles mixed with the desorbed gas become heavier due to contact with the liquid and are intercepted in the treatment tank 24. At the same time, the servo motor 211 is started, and its output shaft drives the rotating rod 210 to rotate. The rotating rod 210 then drives the stirring blade 212 to rotate, causing the washing liquid inside the treatment tank 24 to rotate and move, breaking down larger bubbles and generating more small bubbles, thereby increasing the contact area between the desorbed gas and the washing liquid and enhancing the interception rate of small impurity particles.

[0035] After being washed and filtered, the desorbed gas enters a rectangular space formed by two horizontal partitions 28, one side of the vertical partition 27, and one side of the inner wall of the processing box 24 through the vent holes on the substrate 26 for temporary storage and collection. When the gas pressure in this space accumulates to a certain level, the desorbed gas enters the sleeve 213 through the vent holes on the top cover 25, pushing the slider 222 upward and compressing the spring 221. Once the slider 222 is higher than one end of the second conduit 214, the gas enters the filter 219 through the second conduit 214 for further filtration.

[0036] The desorbed gas, after being finely filtered, is introduced into the compressor 217 for compression. Finally, it is connected to multiple reuse pipes through the five-way pipe 220 at the bottom of the compressor 217, and the compressed desorbed gas is delivered to the production process that needs the gas, thus completing the recycling of the desorbed gas.
