[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1 and Figure 2, a No. 1 guide sleeve 51 and a No. 2 guide sleeve 52 are fixed to the upper side of the water inlet pipe 5 from top to bottom, an upper injection pipe 54 is arranged at an equal angle on the outer side of the No. 1 guide sleeve 51, and a lower injection pipe 55 is arranged at an equal angle on the outer side of the No. 2 guide sleeve 52. The outer oblique sides of the No. 1 guide sleeve 51 and the No. 2 guide sleeve 52 are respectively connected to the upper injection pipe 54 and the lower injection pipe 55 through a sealed rotating pipe joint 53. The upper ends of the upper injection pipe 54 and the lower injection pipe 55 are fixed with a plug rod 56, and the outer side of the plug rod 56 is welded with a direction adjustment gear 57;

[0041] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig.10 The inner wall surface of the purification tower 1 is respectively fixed with a support frame 9 and a reinforcement frame 10 from bottom to top, the insertion rod 56 at the upper end of the upper injection pipe 54 is rotatably connected to the surface of the reinforcement frame 10 through a bearing, and the insertion rod 56 at the upper end of the lower injection pipe 55 is rotatably connected to the surface of the support frame 9 through a bearing;

[0042] Two sets of slide rails 11 are provided on the inner wall of the purification tower 1 close to the support frame 9 and the reinforcement frame 10. An upper rotating drum 12 is connected to the slide rail 11 close to the reinforcement frame 10. A cone bucket 121 is welded to the inner wall of the upper rotating drum 12. A filter plate 122 for increasing the gas-liquid contact surface is provided in the middle of the cone bucket 121. An upper rack 123 and a lower rack 124 are respectively embedded and fixed on the upper side wall and the lower side wall of the cone bucket 121, and the upper rack 123 and the lower rack 124 are both meshed and connected with the adjustment gear 57.

[0043] See also Figure 3-Figure 7 The reserved hole at the bottom end of the cone bucket 121 is connected to the sealing bearing on the outside of the water inlet pipe 5. The water inlet pipe 5 extends into the surface of the No. 1 guide sleeve 51 and the No. 2 guide sleeve 52, and a through hole is provided, and the through hole is used to guide out the reaction liquid for purifying industrial waste gas. The upper injection pipe 54 and the lower injection pipe 55 are distributed in parallel, and the surfaces of the upper injection pipe 54 and the lower injection pipe 55 are provided with injection holes. The diameter of the upper rack 123 is larger than the diameter of the lower rack 124; by starting the booster pump, the reaction liquid in the medicine box 4 is introduced into the No. 1 guide sleeve 51 and the No. 2 guide sleeve 52 along the through holes on the surface of the water inlet pipe 5, so that the reaction liquid is sent to the upper injection pipe 54 and the lower injection pipe 55 along the sealed rotating pipe joint 53 through the No. 1 guide sleeve 51 and the No. 2 guide sleeve 52, so that the reaction liquid sprayed from the upper injection pipe 54 and the lower injection pipe 55 can purify and treat industrial waste gas.

[0044] See also Figure 3-Figure 5An upper annular gear ring 125 is welded to the outer wall of the upper rotating drum 12. Five groups of driven bevel gears 15 and a group of driving bevel gears 16 are connected to the inner side of the purification tower 1 through bearings. The driven bevel gears 15 and the driving bevel gears 16 are meshed and connected with the upper annular gear ring 125. A driving motor 17 is installed on the outer wall of the purification tower 1, and the output end of the driving motor 17 is fixed to the central axis of the driving bevel gear 16.

[0045] During specific implementation, the driving motor 17 is started to drive the active bevel gear 16 to rotate, so that the active bevel gear 16 is meshed with the upper annular gear ring 125 on the outer wall of the upper rotating drum 12, so that the upper rotating drum 12 can drive the cone bucket 121 and the filter plate 122 to rotate forwardly when rotating. Since the water inlet pipe 5 is fixedly arranged and connected to the reserved hole at the bottom of the cone bucket 121 by a sealed bearing, the upper rotating drum 12 can mesh with the direction adjustment gear 57 on the upper injection pipe 54 through the upper rack 123 on the upper side of the cone bucket 121 when rotating forward, thereby driving the direction adjustment gear 57 to rotate in the opposite direction, so that the direction adjustment gear 57 can drive the upper injection pipe 54 to perform reverse motion on the outer side of the No. 1 guide sleeve 51 through the insertion rod 56;

[0046] At the same time, when the upper drum 12 rotates in the forward direction, the lower rack 124 on the lower side of the cone bucket 121 can mesh with the direction-adjusting gear 57 on the lower injection pipe 55, thereby driving the direction-adjusting gear 57 to rotate in the opposite direction, so that the direction-adjusting gear 57 can drive the upper injection pipe 54 to reverse the outer side of the No. 1 guide sleeve 51 through the insertion rod 56. Since the direction-adjusting gear 57 on the upper injection pipe 54 is located on the upper side of the upper rack 123, and the direction-adjusting gear 57 on the lower injection pipe 55 is located on the lower side of the lower rack 124, Therefore, the two groups of direction-adjusting gears 57 located on the upper and lower sides of the cone bucket 121 rotate in opposite directions, so that the upper injection pipe 54 and the lower injection pipe 55 centrifugally throw out the reaction liquid through the injection holes in opposite directions, and the upper injection pipe 54 and the lower injection pipe 55 use opposite directions to swing the reaction liquid to cross-impact the mesh of the filter plate 122. When the industrial waste gas flows upward through the filter plate 122, the surface of the filter plate 122 is cross-impacted by the reaction liquid, so that the reaction liquid has high efficiency and sufficient in purifying the waste gas;

[0047] Since the diameter of the upper rack 123 is greater than that of the lower rack 124, the transmission ratio of the upper rack 123 and the direction-adjusting gear 57 on the upper injection pipe 54 is greater than the transmission ratio of the lower rack 124 and the direction-adjusting gear 57 on the lower injection pipe 55, so that the rotation speed of the upper injection pipe 54 is greater than the rotation speed of the lower injection pipe 55, so that the reaction liquid thrown out by the upper injection pipe 54 has a wider coverage area and a greater impact force, so that when the reaction liquid impacts the filter plate 122 from top to bottom, it can impact and remove the adhesion on the mesh surface of the filter plate 122, thereby ensuring that the purified exhaust gas is discharged without obstruction.

[0048] See also Figure 1 and Figure 2 A water pump 6 is installed at the bottom center of the purification tower 1, and a filter cover 7 is sleeved on the outside of the water pump 6. The top of the filter cover 7 is in contact with the water inlet pipe 5. An annular water pipe 8 is welded to the lower edge of the support frame 9. The annular water pipe 8 is connected to the water pump 6 by a pipeline, and nozzles are equidistantly installed on the surface of the annular water pipe 8.

[0049] During the specific implementation, the filter cover 7 is put on the outside of the water pump 6 to facilitate the isolation and protection of the water pump 6. The reaction liquid collected at the bottom of the purification tower 1 is extracted by the water pump 6, so that the reaction liquid flows back into the annular water pipe 8, and the annular water pipe 8 is sprayed downward through equidistantly installed nozzles, so that the sprayed reaction liquid is reused to cool, reduce dust and remove oil mist for the industrial waste gas ejected from the air duct 3, thereby realizing the pretreatment operation of the industrial waste gas, and then the smoke and oil mist can be removed when purifying the waste gas.

[0050] See also Figure 3 , Figure 4 , Figure 5 and Figure 8 A lower rotating drum 13 is connected to the slide rail 11 located on one side of the support frame 9, and the lower edge of the upper rotating drum 12 is sleeved with the upper edge of the lower rotating drum 13. A lower annular gear ring 131 is welded on the outer surface of the lower rotating drum 13, and the lower annular gear ring 131 is meshed and connected with the driven bevel gear 15 and the active bevel gear 16. When the active bevel gear 16 is driven to rotate by starting the driving motor 17, the active bevel gear 16 can drive the lower annular gear ring 131 and the upper annular gear ring 125 to rotate in opposite directions, thereby driving the lower rotating drum 13 and the upper rotating drum 12 to reverse each other through the lower annular gear ring 131 and the upper annular gear ring 125.

[0051] See also Figure 1 The outer edges of the upper rotating drum 12 and the lower rotating drum 13 are movably connected to the slide rail 11 through the steel balls 14, and the cross section of the slide rail 11 is "C" shaped.

[0052] In specific implementation, the driven bevel gear 15 assists the active bevel gear 16 to drive the lower rotating drum 13 and the upper rotating drum 12 to rotate in opposite directions. During rotation, the lower rotating drum 13 and the upper rotating drum 12 are assisted by rolling in the "C"-shaped slide rail 11 through the steel balls 14, which facilitates the support of the operation of the lower rotating drum 13 and the upper rotating drum 12.

[0053] See also Fig. 9 and Fig.11 The inner wall surface of the lower drum 13 is provided with a wave-shaped driving groove 132, and the surface of the support frame 9 is provided with an adjustment opening 91, which is distributed at equal angles, and a connecting shaft 92 is fixed in the middle of the adjustment opening 91, and the connecting shaft 92 is sleeved with the swinging piece 93;

[0054] See also Figure 3, Figure 4 , Fig. 9 , Fig.10 and Fig.11 A support rod 94 is fixed to one end of the swing piece 93, and a sliding sleeve 95 is sleeved on the outer side of the support rod 94. A guide ball 96 is movably connected to the end of the sliding sleeve 95 away from the swing piece 93. The support rod 94 and the sliding sleeve 95 are telescopically connected. The guide ball 96 is connected to the driving groove 132 on the inner wall surface of the lower rotating drum 13. The cross-section of the driving groove 132 is "C"-shaped, and the guide ball 96 and the wavy driving groove 132 are rollingly connected. The driving groove 132 with a "C"-shaped cross-section can prevent the guide ball 96 from escaping from the driving groove 132.

[0055] In specific implementation, when the lower drum 13 rotates, the guide ball 96 can be driven to move up and down through the driving groove 132 with a wavy surface, so that when the guide ball 96 moves up or down along the wavy driving groove 132, the guide ball 96 will be away from or close to the connecting shaft 92 inside the regulating port 91, so that the guide ball 96 can drive the swing plate 93 to complete the rotation and swing around the connecting shaft 92 through the telescopic connection between the sliding sleeve 95 and the support rod 94, and the reciprocating deflection of the swing plate 93 is realized through the wavy driving groove 132. Since the swing plate 93 is distributed at equal angles in the support frame 9, the reciprocating deflection of the swing plate 93 can slow down the rising flow rate of the exhaust gas, and prolong the contact time between the exhaust gas and the reaction liquid when purifying the exhaust gas. At the same time, the reciprocating deflection of the swing plate 93 can oscillate the reaction liquid dripping from top to bottom, so that the reaction liquid splashes on the swing plate 93, thereby achieving the goal of breaking up the dripping reaction liquid to cover the internal space of the support frame 9, ensuring that the device has a centralized treatment effect when purifying the exhaust gas.

[0056] See also Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.11 A drainage port 97 is provided at an equal angle on the lower side surface of the support frame 9 . By providing the drainage port 97 at an equal angle on the lower side surface of the support frame 9 , the reaction liquid adhered to the surface of the support frame 9 can drip downward along the drainage port 97 .

[0057] See also Figure 1 A tower cover 18 is installed on the top of the purification tower 1, and an air outlet pipe 19 is arranged in the middle of the tower cover 18. An exhaust fan 20 is installed inside the air outlet pipe 19. An air hood 21 is sleeved on the outer side of the air outlet pipe 19. The upper edge of the air hood 21 is threadedly connected to the lower edge of the tower cover 18. An isolation barrel 23 is arranged between the air hood 21 and the air outlet pipe 19. An adsorption bin 22 for filling active blocks is fixed between the isolation barrel 23 and the air hood 21. The air outlet pipe 19, the air hood 21 and the isolation barrel 23 are coaxially arranged, and the opening of the isolation barrel 23 is arranged upward.

[0058] In specific implementation, when the waste gas is purified by the reaction liquid, the exhaust fan 20 inside the air outlet pipe 19 is started so that the exhaust fan 20 discharges the gas inside the purification tower 1 to the outside, so that the gas is sent along the induced draft hood 21 into the adsorption bin 22 for deodorization by the activated carbon, and the gas that has completed the deodorization flows into the isolation barrel 23, and then is discharged from the tower cover 18 along the air outlet pipe 19, so as to ensure that the waste gas can be deodorized after purification; when maintaining the purification device, the tower cover 18 is removed from the top of the purification tower 1, and the induced draft hood 21 and the tower cover 18 are rotated to separate the two, so as to facilitate the maintenance of the activated carbon in the adsorption bin 22, and also facilitate the inspection and maintenance of the exhaust fan 20.

[0059] A method for using an air pollution control and purification device comprises the following steps:

[0060] S1: introducing the industrial waste gas into the purification tower 1 through the induced draft fan 2, and extracting the reaction liquid in the medicine box 4 to spray the industrial waste gas in the purification tower 1;

[0061] S2: The reaction liquid at the bottom of the purification tower 1 is extracted by the water pump 6 and then passed through the annular water pipe 8 to cool down and reduce the high-temperature smoke in the exhaust gas;
