[0003] The prior art still has the following defects for industrial waste gas purification: The waste gas deep purification device usually adopts catalytic oxidation, spraying absorption or active adsorption, and in the whole process of waste gas purification, sufficient dust removal must be carried out to ensure better purification effect, especially for the active adsorption mode, because the dust content in the waste gas is large and accompanied by water vapor, which will greatly reduce the adsorption effect of the adsorption plate, and the dust accompanied by water vapor will block the surface fine pores of the adsorption plate, thereby reducing the service life of the adsorption plate.

[0004] The adsorption plate in the current waste gas deep purification device has a small area of contact with waste gas, resulting in poor effect of active adsorption purification of waste gas, and the waste gas moves between adjacent two adsorption plates, and the waste gas located in the middle is difficult to contact with the adsorption plate, thereby affecting the effect of active adsorption purification of waste gas.

[0038] In the initial state, there is a gap between the two sides of the processing assembly and the adjacent two W-shaped adsorption plates 23.

[0039] The specific use method of the present application: The industrial waste gas is transported into the electric dust removal mechanism 11 through the air inlet pipe 13, and the electric dust removal mechanism 11 is used to remove dust from the industrial waste gas. The treated waste gas in the electric dust removal mechanism 11 is transported into the spraying mechanism 12 through the first air pipe 14, and the spraying mechanism 12 is used to spray and remove impurities and cool the waste gas. The treated waste gas is transported into the shell 10 through the second air pipe 15. The waste gas in the shell 10 moves into the casing 19. Since the inside of the casing 19 is formed into an S-shaped channel by a plurality of pairs of staggered partition plates 22, the moving distance of the waste gas in the casing 19 is prolonged, which is beneficial to improve the purification effect of the W-shaped adsorption plate 23 on the waste gas. And there are a plurality of W-shaped adsorption plates 23 between each adjacent two partition plates 22, so that a plurality of groups of W-shaped adsorption plates 23 are used to purify the waste gas in multiple stages, thereby greatly improving the effect of deep purification of the waste gas.

[0040] At the same time, the shape of the W-shaped adsorption plate 23 increases the contact area between the W-shaped adsorption plate 23 and the waste gas, which is beneficial to make the W-shaped adsorption plate 23 fully contact with the waste gas, thereby improving the purification effect of the W-shaped adsorption plate 23 on the waste gas. The treatment assembly is located between the adjacent two W-shaped adsorption plates 23, and there is a gap between the two sides of the treatment assembly and the adjacent two W-shaped adsorption plates 23, so that the treatment assembly is used to guide the waste gas, so that the waste gas moves towards the surface of the two W-shaped adsorption plates 23, which further improves the full contact between the waste gas and the W-shaped adsorption plate 23, and improves the purification effect of the W-shaped adsorption plate 23 on the waste gas.

[0041] The waste gas after multiple-stage deep purification moves to one end of the shell 10 close to the air outlet pipe 16, and the detector 73 detects the gas. The qualified gas is discharged through the air outlet pipe 16.

[0042] When the detector 73 detects unqualified gas, the electromagnetic valve in the conveying pipe 74 is opened, so that the waste gas in the shell 10 is transported into the air inlet pipe 13 through the conveying pipe 74 for reprocessing.

[0043] After a long time of active adsorption purification of the exhaust gas, the pores on the surface of the W-shaped adsorption plate 23 are easily blocked by impurities, thereby affecting the active adsorption purification of the exhaust gas by the W-shaped adsorption plate 23. The control system controls a plurality of stepping motors 57 to start, and the stepping motors 57 drive one of the rotating rods 25 to rotate, and the rotating rod 25 drives the first gear 60 to rotate. By using the outer wall of the first gear 60 and the outer wall of a plurality of second gears 61, the rotation of one of the rotating rods 25 can synchronously drive the remaining rotating rods 25 to rotate. By using the outer wall of the rotating rod 25 and the threaded contact of the W-shaped block 24 in the processing assembly, and the W-shaped block 24 is limited between the adjacent two partitions 22, so that the processing assembly can move up and down. Among them, the processing assembly on one of the rotating rods 25 is at the lowest position, and the processing assemblies on the remaining rotating rods 25 are at the highest position. The positive rotation of one of the rotating rods 25 drives the processing assembly to move upwards, and the reverse rotation of the remaining rotating rods 25 drives the processing assembly to move downwards.

[0044] The rotation of one of the rotating rods 25 drives the sliding block 65 to rotate, and the sliding block 65 rotates and spirally slides in the spiral sliding groove 63, thereby driving the first sleeve 62 and the movable plate 21 to slide up and down. When the movable plate 21 moves upwards, the movable plate 21 absorbs the strong oxidizing agent in the strong oxidizing agent tank 54 into the frame 20, and absorbs the high-temperature gas in the high-temperature tank 55 into the frame 20. Among them, the gas in the high-temperature tank 55 is supplemented by the gas valve 70, and the gas in the high-temperature tank 55 is heated by the heater 56.

[0045] When the movable plate 21 moves downwards, the movable plate 21 moves downwards to transport the high-temperature gas and the strong oxidizing agent in the frame 20 to the W-shaped hydraulic cavity 41 in the W-shaped block 24 through a plurality of telescopic connecting pipes 26, respectively. At this time, due to the effect of the elastic force of the second spring 52 on the circular cover 49, the circular cover 49 covers one end of the connecting pipe 43, so that the inside of the connecting pipe 43 and the inside of the W-shaped hydraulic cavity 41 are blocked and not connected. The mixed gas in the W-shaped hydraulic cavity 41 pushes the two W-shaped piston plates 42 away from each other. The movement of the W-shaped piston plate 42 drives the connecting pipe 43 and the push plate 44 to move, and the movement of the push plate 44 drives the two second elastic members 59 and the cleaning member 28 to move horizontally. The horizontal movement of the cleaning member 28 drives the brush block 33 to move horizontally and contact one side wall of the W-shaped adsorption plate 23, so that a plurality of pairs of brush blocks 33 are in contact with one side wall of the W-shaped adsorption plate 23, and the vertical movement of the W-shaped block 24 drives a plurality of pairs of cleaning members 28 and brush blocks 33 to move vertically, thereby using a plurality of pairs of cleaning members 28 and brush blocks 33 to clean the impurities attached to the surface of the W-shaped adsorption plate 23. Among them, the horizontal movement of the W-shaped piston plate 42 compresses the first spring 51 to generate elastic force. The two ends of the rotating shaft 29 slide in the two sliding grooves 58, thereby enabling the cleaning member 28 and the rotating shaft 29 to move horizontally stably.

[0046] Meanwhile, the horizontal movement of the cleaning piece 28 drives the horizontal movement of the second protrusion 32, which is guided by the first protrusions 31, so that the cleaning piece 28 swings around the rotating shaft 29. The horizontal movement of each pair of cleaning pieces 28 drives the horizontal movement of two second protrusions 32, which is guided by several pairs of first protrusions 31, so that one end of each pair of cleaning pieces 28 swings away from each other. The swinging of the cleaning piece 28 drives the swinging of the brush block 33 and the scraping piece 34, so that the impurities on the surface of the W-shaped adsorption plate 23 are first preliminarily cleaned by the swinging brush block 33; and then scraped by the second extension 37, the third extension 38, and the first extension 35, so as to quickly restore the active adsorption effect of the W-shaped adsorption plate 23.

[0047] Meanwhile, since the first extension 35 is supported by the first elastic piece 36, the gap between one end of the third extension 38 and one end of the first extension 35 is small, so that the degree of extrusion deformation of the third extension 38 is small. And the gap between one end of the second extension 37 and one end of the first extension 35 is large, so that the degree of contact deformation of one end of the second extension 37 with the surface of the W-shaped adsorption plate 23 is large, thereby reducing the distance between the second extension 37 and the third extension 38. Therefore, the end of the second extension 37 is deformed and moved to cooperate with the relatively fixed end of the third extension 38, so as to extrude and deform the first V-shaped elastic piece 39. The deformation of the first V-shaped elastic piece 39 drives the sharp block 40 to protrude and pierce the relatively firm impurities, so as to quickly clean the relatively firm impurities by the third extension 38 and the first extension 35, greatly improving the cleaning effect on the surface of the W-shaped adsorption plate 23. Among them, the two second V-shaped elastic pieces 71 guide and limit the sharp block 40, which can make the sharp block 40 smoothly protrude to pierce the relatively firm impurities.

[0048] Finally, the W-shaped piston plate 42 moves horizontally to drive the circular cover 49 and the top rod 53 to move horizontally, and one end of the top rod 53 is in contact with one end of the W-shaped hydraulic cavity 41, so that one end of the top rod 53 is resisted by one end of the W-shaped hydraulic cavity 41. The W-shaped piston plate 42 continues to move horizontally, thereby resisting the circular cover 49 by using the top rod 53 to move relatively fixed, and the one end of the circular cover 49 slides out of the W-shaped piston plate 42. At this time, the mixed gas in the W-shaped hydraulic cavity 41 is transported into the connecting pipe 43 through the through hole 50, and the mixed gas in the connecting pipe 43 is sprayed to contact the wind wheel 48, thereby driving the wind wheel 48 and the circular pipe 45 to rotate by using the high-pressure spray of the mixed gas. A part of the mixed gas is transported into the circular disc 46 through the circular pipe 45. The circular pipe 45 drives the circular disc 46 to rotate, and the circular disc 46 drives the plurality of nozzles 47 to rotate, and the mixed gas in the circular disc 46 is spirally sprayed by using the rotation of the plurality of nozzles 47, thereby expanding the contact range of the mixed gas with the surface of the W-shaped adsorption plate 23. Among them, the mixed gas includes high-temperature gas and strong oxidant. The W-shaped adsorption plate 23 is steam purged by using the high-temperature gas, so that the volatile organic matter is desorbed and recovered. And the W-shaped adsorption plate 23 is heated by using the high-temperature gas, so that the adsorbed organic matter is volatilized or decomposed, and the pore structure is restored. Finally, the adsorbed organic matter is decomposed by using the strong oxidant (such as ozone, hydrogen peroxide), which is suitable for treating refractory pollutants, but may corrode the adsorption plate material, thereby greatly improving the high-temperature chemical recovery activity of the W-shaped adsorption plate 23, and prolonging the service life of the W-shaped adsorption plate 23.

[0049] Therefore, the movable plate 21 moves up and down in the frame 20, and under the action of the high-pressure pushing of the mixed gas and the elastic force of the first spring 51, the W-shaped piston plate 42 can move horizontally in the W-shaped hydraulic cavity 41. During the horizontal movement of the W-shaped piston plate 42, the two cleaning pieces 28 can swing back and forth under the guidance of the plurality of first protrusions 31 and the elastic force of the two second elastic pieces 59. In order to clean the surface of the W-shaped adsorption plate 23 quickly by using the swing of the cleaning piece 28 and the mixed gas, the W-shaped adsorption plate 23 can be quickly recovered, and the service life of the W-shaped adsorption plate 23 can be prolonged.
