The water storage tank 4 is filled with water, the water pump 8 is arranged in the water storage tank 4, and the water in the water storage tank 4 is pumped to the water distribution roller 5 under the action of the water pump 8 and then flows to the filter screen 3 along the water distribution roller 5. An air inlet 6 is arranged at the upper part of the shell 1, an air outlet 7 is arranged at the lower part of the shell, a flow passage through which air flows is formed between the air inlet 6 and the air outlet 7 in the shell 1, a filter screen 3 is arranged in the flow passage, and the air passes through meshes of the filter screen 3 when flowing. Since the filter net 3 is sprayed with water, the air containing dust is adsorbed on the filter net 3 while passing through the filter net 3, thereby reducing the dust content in the air. The motor 9 drives the water distributor to rotate when in work, water is evenly sprayed on the filter screen 3, water films can be coated on a plurality of places on the filter screen 3, and dust is adsorbed when air passes through the water films. A plurality of filter screens 3 are arranged in the shell 1, and air needs to pass through the plurality of layers of filter screens 3 when flowing in the shell 1, so that dust in the air is adsorbed, and the filtering effect of the air is improved. Because the water distribution roller 5 rotates above the filter screen 3, water is continuously sprayed on each part of the filter screen 3, and water is quickly sprayed again in the area of the filter screen 3 where the water is volatilized to improve the dust adsorption area of the filter screen 3. The water distribution roller 5 can also play a role in scrubbing the filter screen 3 when rolling along the surface of the filter screen 3, and can clean dirt on the filter screen 3 in time. After water discharged from the water pump 8 is sprayed to the water distribution roller 5, the water is sprayed to the filter screen 3 along the water distribution roller 5, and the water is not easy to block in the circulating flow process.
