[0002] At present, industrial waste gas is a major source of pollution in society. Various toxic gases contained in industrial waste gas, such as sulfur dioxide, hydrogen sulfide, etc., and some particulate matters cause serious harm to the public environment, resulting in natural disasters such as acid rain. Industrial waste gas is one of the main sources of air pollution

[0003] For example, an environment-friendly industrial waste gas purification device provided with the publication number CN108671656A includes telescopic legs. A support platform is fixedly arranged at the top of the telescopic legs. A purification water tank is arranged on the top of the support platform. A dust removal box is fixedly arranged on the top of the purification water tank.

A first driving motor is fixedly installed on one side of the filter screen, and the filter screen can filter large particles in the waste gas

[0004] However, the above scheme has the following deficiencies: In the above patent, the surface of the filter screen is cleaned by the rotation of the scraper to prevent the filter screen from being blocked. The purified and filtered gas is discharged through the exhaust holes on the outer side of the hollow drum, so that the waste gas is fully contacted with the absorption liquid in the inner cavity of the purification water tank to improve the waste gas purification efficiency. However, during the rotation of the scraper, some dust particles may be squeezed into the inside of the filter screen, causing blockage inside the filter screen, and the rotation of the scraper can only clean the surface of the filter screen and cannot clean the dust inside the filter screen. For this reason, we introduce a waste gas absorption mechanism and a waste gas purification device Content of the Utility Model

The absorption chambers 20 are communicated with the first connecting chamber 17. The motor 3 is turned on to drive the connecting shaft 16 connected to its output end to start rotating. The rotation of the connecting shaft 16 drives several groups of connecting plates 19 to rotate. When the connecting plates 19 rotate, the cleaning brush 15 is driven to clean the particles on the surface of the particle filter plate 5.

[0027] The dust extraction mechanism includes a second connection cavity 8. The second connection cavity 8 is formed inside the left support rod 4. An electromagnetic valve 7 is fixedly connected inside the second connection cavity 8. During actual use, an electromagnetic valve 7 with a suitable size can be selected. One end of the second connection cavity 8 is communicated with the first connection cavity 17, and the other end is communicated with the output end of the exhaust fan 6. The exhaust fan 6 is fixedly installed at the upper end of the waste gas treatment column 1. By turning on several vibrators 18, the particles in the particle filter plate 5 become loose, facilitating the cleaning by the cleaning brush 15. By turning on the exhaust fan 6 and the electromagnetic valve 7, the cleaned particles are sucked into the absorption cavity 20. The particles then enter the second connection cavity 8 through the first connection cavity 17 and are finally discharged through the exhaust fan 6. The specific model of the exhaust fan 6 is CX-150 produced by Jiangsu Jieshuo Environmental Protection Technology Co., Ltd.;

[0028] The waste gas absorption mechanism includes a liquid storage cavity 11. The liquid storage cavity 11 is formed inside the waste gas treatment column 1. The lower end of the guiding pipe 12 extends into the liquid storage cavity 11. An absorption liquid is provided inside the liquid storage cavity 11. The liquid storage cavity 11 is communicated with the cavity 9. The cavity 9 is formed inside the waste gas treatment column 1. A drying and adsorption plate 13 is fixedly connected inside the cavity 9. The drying and adsorption plate 13 arranged inside the cavity 9 is composed of a drying plate and an activated carbon adsorption plate. Therefore, the air is dried by the drying plate when passing through the drying and adsorption plate 13, and the toxic gases insoluble in water in the waste gas are adsorbed by the activated carbon adsorption plate. Exhaust pipes 14 are fixedly connected inside the left side and the lower end of the waste gas treatment column 1.

The specific model of the vibrator 18 is the MVE-DC type vibration motor produced by Kunshan Beitente Electromechanical Co., Ltd. During actual use, a suitable size can be selected according to the size of the particle filter plate 5.

[0029] In addition, to achieve the above object, the present invention also provides a waste gas purification device, including the above-mentioned waste gas absorption mechanism.

[0030] Working principle: During use, connect the exhaust pipe 14 on the left to the waste gas pipe so that the waste gas can enter the treatment chamber 2 through the exhaust pipe 14 on the left. The waste gas entering the treatment chamber 2 is filtered after passing through the particle filter plate 5. The gas with the particles filtered out passes through the first one-way valve 10 and enters the guiding pipe 12. The gas entering the guiding pipe 12 enters the liquid storage chamber 11 and contacts the absorption liquid to improve the purification efficiency of the waste gas. The gas passing through the absorption liquid then enters the cavity 9. The drying adsorption plate 13 arranged in the cavity 9 is composed of a drying plate and an activated carbon adsorption plate. Therefore, when the air passes through the drying adsorption plate 13, it is dried by the drying plate, and the toxic gas insoluble in water in the waste gas is adsorbed by the activated carbon adsorption plate. The treated gas finally is discharged through the exhaust pipe 14;

[0031] When it is necessary to clean the particle filter plate 5, at this time, turn on the motor 3 to drive the connecting shaft 16 connected to its output end to start rotating. The rotation of the connecting shaft 16 drives several groups of connecting plates 19 to rotate. When the connecting plates 19 rotate, they drive the cleaning brush 15 to clean the particles on the surface of the particle filter plate 5. At the same time, by turning on several groups of vibrators 18, the particles in the particle filter plate 5 become loose, which is convenient for the cleaning of the cleaning brush 15. By turning on the exhaust fan 6 and the solenoid valve 7, the cleaned particles are sucked into the absorption chamber 20. The particles then enter the second connection chamber 8 through the first connection chamber 17 and are finally discharged through the exhaust fan 6. During the process of sucking and discharging the particles, the waste gas pipe needs to be closed. The setting of the second one-way valve 21 enables external gas to enter the treatment chamber 2 when the exhaust fan 6 is working.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
