[0028] Reciprocating drive mechanism includes two mounting frames 14 fixedly installed on the top of spray adsorption box 1, reciprocating lead screw 15 is rotatably connected between the two mounting frames 14, reciprocating moving block 16 is screw-connected on the outer surface of reciprocating lead screw 15, guide rod 17 is movably inserted in the inside of reciprocating moving block 16, and guide rod 17 is fixedly installed between the two mounting frames 14, one of the two mounting frames 14 is fixedly connected with driving motor 18, and the output end of driving motor 18 is coaxially fixedly connected with reciprocating lead screw 15;

[0029] When the particulate impurities adsorbed on filtering plate 3 need to be cleaned and maintained, driving motor 18 is started by control panel 22, the output end of driving motor 18 rotates to drive reciprocating lead screw 15 to rotate, and reciprocating moving block 16 reciprocates along the axial direction of reciprocating lead screw 15 under the limiting action of guide rod 17, then cleaning brush 6 is driven to reciprocate by connecting frame 4 and vertical rod 5, and then the particulate impurities adsorbed on filtering plate 3 are brushed off by moving cleaning brush 6, realizing the automatic cleaning treatment of filtering plate 3, replacing traditional manual cleaning, reducing the labor intensity of workers, and the cleaning operation of filtering plate 3 can be carried out during the operation of the equipment, without stopping the equipment, ensuring the efficient treatment of waste gas by the equipment.

[0030] The top and bottom of the inner wall of the spray adsorption box 1 are fixedly connected with U-shaped positioning frames 19, and an activated carbon adsorption plate 20 is movably installed between the two U-shaped positioning frames 19. The activated carbon adsorption plate 20 can adsorb and purify the waste gas after spray adsorption.

[0031] A maintenance door 21 is hingedly installed on the front of the spray adsorption box 1 and corresponds to the position of the activated carbon adsorption plate 20. A control panel 22 is fixedly installed on the front of the maintenance door 21.

[0032] The drainage mechanism includes a plurality of drainage branch pipes 23 fixedly and communicatively installed at the bottom end of the sewage tank 2. The bottom ends of the plurality of drainage branch pipes 23 are fixedly and communicatively connected with the same drainage main pipe 24. The drainage main pipe 24 is provided with a solenoid valve 2.

[0033] Working principle: when in use, the liquid supply pipe 9 is communicated with an external water source. The selection of the water source is adaptive according to the characteristics of the waste gas to be treated (for example, if the waste gas to be treated is acid-base waste gas, the water source is selected to be acid-base neutralizing liquid, and if the waste gas to be treated is ordinary dust waste gas, the water source is selected to be clean water). Then the waste gas to be treated enters the spray adsorption box 1 through the air inlet pipe 7. The plurality of filter plates 3 filter and intercept the particulate impurities in the waste gas. At the same time, the solenoid valve 1 is opened through the control panel 22. The liquid supply pipe 9 delivers the water source to the spray pipe 10 and sprays vertically through the vertical spray nozzle 11, thereby spray adsorbing the waste gas entering the spray adsorption box 1. The inclined spray nozzle 12 sprays the water source obliquely to the filter plate 3, so that the part of the particulate impurities adsorbed on the filter plate 3 will fall with the water flow, thereby achieving the effect of water cleaning and cleaning the filter plate 3.

[0034] After the spray adsorption treatment, the waste gas flows to the activated carbon adsorption plate 20. The activated carbon adsorption plate 20 adsorbs and filters the harmful gas in the waste gas, thereby purifying the gas. Then the waste gas is discharged from the exhaust pipe 8 to the spray adsorption box 1.

[0035] When it is necessary to clean and maintain the particulate impurities adsorbed on the filter plate 3, the drive motor 18 is started through the control panel 22. The output end of the drive motor 18 rotates to drive the reciprocating lead screw 15 to rotate. Under the limiting action of the guide rod 17 on the reciprocating moving block 16, the reciprocating moving block 16 reciprocates along the axis of the reciprocating lead screw 15. Then the cleaning brush 6 is driven to reciprocate through the connecting frame 4 and the vertical rod 5. Then the particulate impurities adsorbed on the filter plate 3 are brushed off through the moving cleaning brush 6, thereby realizing the automatic cleaning of the filter plate 3, replacing the traditional manual cleaning, reducing the labor intensity of workers, and enabling the cleaning of the filter plate 3 during the operation of the equipment, without the need to stop the equipment, thereby ensuring the efficient treatment of the waste gas by the equipment.

[0036] The spray sewage and the granular impurities filtered and intercepted by the filter plate 3 are collected by the sewage tank 2, when the sewage in the sewage tank 2 needs to be discharged, the electromagnetic valve two 25 is opened through the control panel 22, then the sewage in the sewage tank 2 can be discharged outward through the cooperation of the drainage branch pipe 23 and the drainage main pipe 24.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
