The first motor drives the driving shaft to rotate, and the driving shaft drives the driven shaft to rotate under the action of the driving gear and the driven gear, thereby driving the spray head on the driven shaft to continuously rotate and spray water to fall dust, making the spraying more uniform. The dust falling air is filtered by the filter screen and discharged from the box after being adsorbed by the activated carbon adsorption layer. The water used for dust falling is discharged from the drain to the filter box and filtered by the filter plate, then flows into the water tank through the water pump for recycling, saving water resources. The spray head on the cross pipe is used for spraying and dust removal, increasing the dust removal efficiency. The driving motor drives the cam to rotate, and the cam rotates to continuously hit the left and right rollers, which can prevent the filter plate from being blocked and affect the filtering speed. The device has simple structure, high dust removal efficiency and strong practicability.
