[0021] By means of the rotating pipe 2 arranged in the inner cavity of the dust reduction bin 1 and the water tank 4 arranged on the top of the dust reduction bin 1, when the exhaust gas enters the inner cavity of the dust reduction bin 1 again, the water in the inner cavity of the water tank 4 can be released under the action of the rotating pipe 2 and the nozzle 3, so that the inner cavity of the dust reduction bin 1 is filled with water mist, thereby playing a role in treating the dust in the exhaust gas under the action of the water mist.

[0022] In a preferred embodiment, the outer wall of the connecting tube 5 is rotatably connected in the inner cavity of the rotating tube 2 , and the outer wall of the driven gear 6 and the outer wall of the driving gear 8 are meshed with each other.

[0023] By rotationally connecting the outer wall of the connecting pipe 5 with the outer wall of the rotating pipe 2, when the rotating pipe 2 rotates under the action of the driving motor 7, since the outer wall of the connecting pipe 5 and the outer wall of the rotating pipe 2 are rotationally connected, the inner cavity of the rotating pipe 2 can be supplied with water normally through the connecting pipe 5 during the normal rotation of the rotating pipe 2.

[0024] In a preferred embodiment: an atomizing nozzle is fixedly mounted on the outer wall of the nozzle 3 , a controller is fixedly mounted on the outer wall of the dust suppression bin 1 , and the controller is electrically connected to the driving motor 7 .

[0025] By installing an atomizing nozzle on the outer wall of the nozzle 3, the water flow can be converted into water mist under the action of the rotating tube 2, the nozzle 3 and the atomizing nozzle, so that the inner cavity of the dust reduction bin 1 is filled with water mist, thereby increasing the contact area between the water mist and the exhaust gas, thereby achieving a better dust removal effect.

[0026] In a preferred embodiment, two ends of the telescopic spring 14 are in contact with the outer wall of the pressing plate 13 and the inner wall of the U-shaped plate 10 respectively, and the telescopic spring 14 is made of high carbon steel.

[0032] Working principle: When the above-mentioned equipment is in use, the exhaust gas is introduced into the inner cavity of the dust suppression bin 1, and then the driving motor 7 is started. Under the action of the driving motor 7, the driving gear 8 is driven to rotate, so that the rotating tube 2 is rotated under the action of the driving gear 8. During the rotation of the rotating tube 2, the water tank 4 continuously supplies water to the inner cavity of the rotating tube 2 through the connecting pipe 5, and then releases the water into the inner cavity of the dust suppression bin 1 through the nozzle 3 and the atomizing nozzle. At this time, the dust in the exhaust gas is processed under the action of the water mist, and then the exhaust gas treated by the dust suppression is again It enters the inner cavity of the adsorption bin 9 and adsorbs large particles of impurities contained in the exhaust gas under the action of the filter plate 12, so that harmful substances and large particles of impurities in the exhaust gas are removed. During the use of the filter plate 12, when the filter plate 12 needs to be replaced, it is only necessary to pull the pull rod 11 to compress the telescopic spring 14 and the outer wall of the pressure plate 13 leaves the outer wall of the filter plate 12. At this time, the U-shaped plate 10 is rotated to make the U-shaped plate 10 leave the outer wall of the filter plate 12, thereby realizing the replacement of the filter plate 12, which is very convenient.
