[0021] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a transformer adsorption device convenient for assembly, including an exhaust pipe 1, a first valve 2 is connected to the surface of the exhaust pipe 1, an adsorption assembly is connected to the bottom of the exhaust pipe 1, a pretreatment assembly is installed at the bottom of the adsorption assembly, a first pipe 3 is connected to one side of the adsorption assembly, a second valve 4 is connected to the surface of the first pipe 3, and a compressor 5 is connected to the end of the first pipe 3 far from the adsorption assembly; a second pipe 6 is connected to the other side of the adsorption assembly, a third valve 7 is connected to the surface of the second pipe 6, a third pipe 8 is connected to the end of the third pipe 8 far from the adsorption assembly, and a vacuum pump 9 is connected to the surface of the vacuum pump 9, and a controller 10 is installed on the surface of the vacuum pump 9.

[0023] The first valve 2 can be opened through the controller 10 to discharge the treated industrial waste gas through the exhaust pipe 1. By controlling the cooperation between the compressor 5 and the vacuum pump 9, the pressure inside the adsorption assembly can be changed.

[0024] Further, the adsorption assembly includes an adsorption tower 11. The top of the adsorption tower 11 is connected to the bottom of the exhaust pipe 1, and both sides of the adsorption tower 11 are respectively connected to one ends of the first pipe 3 and the second pipe 6; a baffle 12 is installed inside the adsorption tower 11, a high-efficiency adsorbent 13 is installed on the upper surface of the baffle 12, and through holes 14 are formed on the surface of the baffle 12; a gas monitoring sensor 15 is installed at the top of the inner wall of the adsorption tower 11, and a pressure sensor 16 is installed at the bottom of the inner wall of the adsorption tower 11. When the industrial waste gas enters the adsorption tower 11, the second valve 4 on the surface of the first pipe 3 is opened, and the compressor 5 compresses the gas inside the adsorption tower 11. The pressure sensor 16 senses the pressure inside the adsorption tower 11 and feeds it back to the controller 10, and it can be adaptively adjusted according to the pressure required to adsorb the target gas. Under high pressure, the industrial waste gas passes through the through holes 14 on the surface of the baffle 12 and passes through the high-efficiency adsorbent 13. The target gas can be adsorbed through the high-efficiency adsorbent 13, and at the same time, the first valve 2 on the surface of the exhaust pipe 1 is opened to discharge the treated industrial waste gas through the exhaust pipe 1.

[0025] One side of the exhaust pipe 1 is connected to a third pipe 8, and the surface of the third pipe 8 is connected to a fourth valve 26. When the high-efficiency adsorbent 13 is in a saturated state and unable to adsorb the target gas, the gas detection sensor above the high-efficiency adsorbent 13 detects that the target gas has not been adsorbed and feeds back to the controller 10. At this time, the first valve 2 on the surface of the exhaust pipe 1 and the second valve 4 on the surface of the first pipe 3 are closed, and the third valve 7 on the surface of the second pipe 6 is opened. At this time, the vacuum pump 9 works according to the pressure required to desorb the target gas and the information fed back to the controller 10 by the pressure sensor 16, so that the target gas is desorbed from the high-efficiency adsorbent 13. At this time, the fourth valve 26 on the surface of the third pipe 8 is opened, so that the desorbed target gas is recovered or utilized through the third pipe 8, thereby achieving the purpose of more efficient treatment of industrial waste gas.

[0026] Furthermore, the pretreatment component includes a fourth pipe 17. The top of the fourth pipe 17 is connected to the bottom of the adsorption tower 11. The surface of the fourth pipe 17 is connected to a fifth valve 18. The bottom of the fourth pipe 17 is connected to a tank body 19. The bottom of the tank body 19 is connected to a fifth pipe 20. The surface of the fifth pipe 20 is connected to a sixth valve 21; a dust-proof net 22 is installed inside the tank body 19, a vibrator 25 is installed on the outer surface of the tank body 19, one side of the tank body 19 is connected to an air inlet 23, and the surface of the air inlet 23 is connected to a seventh valve 24. Through the fourth pipe 17, the tank body 19 can be connected to the adsorption tower 11. Industrial waste gas enters the tank body 19 through the seventh valve 24 on the surface of the air inlet 23. The particulate dust in the industrial waste gas can be filtered through the dust-proof net. The pretreated industrial waste gas enters the adsorption tower 11 through the fifth valve 18 on the surface of the fourth pipe 17. By the operation of the vibrator 25 installed on the surface of the tank body 19, the output end of the vibrator 25 drives the tank body 19 to vibrate at the same frequency, so that the particulate dust on the dust-proof net 22 is separated from the dust-proof net 22, and the particulate dust is recovered or utilized through the sixth valve 21 on the surface of the fifth pipe 20.

[0027] By dividing the device into multiple plates such as the adsorption component, each plate can be manufactured and tested separately and connected in a standardized manner through pipes, so as to achieve the purpose of facilitating assembly and deployment.
