[0033] Embodiment 2:

[0034] like Figure 1-Figure 12As shown, the working principle of a coal mill filtering and processing system disclosed in the utility model is: the operator first pulls out the air inlet buckle 103, so that the air inlet buckle 103 is separated from the air inlet fixing ring 104, and the cross protrusion on the air inlet buckle 103 is separated from the cross groove on the air inlet gear 102, and manually rotates the air inlet fixing ring 104 to make the air inlet gear 102 rotate and drive the air inlet fan blades 101 to flip to the desired position, adjust the deflection angle of the air inlet fan blades 101, and then adjust the incoming air volume. After adjusting the position of the air inlet fan blades 101, restore the air inlet buckle 103 to its initial position, and the magnetic material inside the air inlet buckle 103 enables the air inlet buckle 103 to fit tightly against the air inlet fixing ring 104.

[0035] The device is placed at the desired position, and the dust reduction motor 201 is turned on. The dust reduction motor 201 rotates to drive the dust reduction active gear 202 and the air inlet rotating ring 105 to rotate. The air inlet rotating ring 105 rotates to drive the air inlet fixed ring 104 locked by the air inlet buckle 103 to rotate. The air inlet fixed ring 104 rotates to suck the air containing coal powder into the air inlet conical shell 106, and enters the inner shell 4 through the air inlet conical shell 106. When the dust reduction active gear 202 rotates, it drives the dust reduction gear 1 207. The dust reduction gear 1 207 drives the dust reduction column gear 206 and the dust reduction fan blade 203. When the dust reduction gear 1 207 and the dust reduction column gear 206 rotate, they respectively drive the dust reduction gear 2 210 and the dust reduction gear ring 211 to rotate. The dynamic ratio is different. The dust reduction gear ring 211 has the same transmission ratio as the dust reduction gear 210, so that the dust reduction gear ring 211 and the protrusion on the dust reduction gear 210 slide in cooperation, pushing the dust reduction gear ring 211 and the dust reduction ring 208 to slide and compress the dust reduction water storage tank 204. When the dust reduction ring 208 slides, the atomizing sliding column 305 is driven by the atomizing connecting rod 301 to slide toward the atomizing ball 304, opening the channel formed by the atomizing ball 304 and the atomizing tube 302. The water in the water tank 5 flows into the dust reduction water storage tank 204 through the channel and enters the dust reduction nozzle 209. At the same time, it is atomized by the holes on the dust reduction nozzle 209 to flush the exhaust gas entering the inner shell 4, reduce impurities in the exhaust gas, and the dust reduction fan blades 203 rotate to fully mix the atomized water vapor with the exhaust gas to ensure the cleaning quality.

[0036] The waste gas treated with atomized water is discharged from the outlet at the top of the inner shell 4. A filter is provided in the outlet to reduce the humidity of the exhaust gas. Small water droplets containing impurities fall to the bottom of the inner shell 4 under the action of gravity. The pump provided on the atomizing pipe 306 sucks the sewage through the atomizing pipe 306 and into the water tank 5 for recycling, thereby achieving the purpose of energy saving and emission reduction.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
