S3, after entering the gap between the partition board 1-6 and the cylindrical electrostatic purifier 1-2, the air flows upwards, and when reaching the lower part of the flying disc type electrostatic purifier 1-3, the small water mist sprayer 1-11 sprays and purifies the air, so that secondary air purification is realized, and therefore, a two-stage purification effect can be achieved when water mist purification is utilized, and the air purification effect is guaranteed.

S4, the water mist is discharged through the discharge openings 1-14 and the flow pipes 1-5.

And S5, stopping water inflow after a certain time interval, and circulating according to the steps 1-4. The moisture in the electrostatic precipitator can be air-dried while blowing air in step 1. The water spraying time can be set to be 5-20 minutes, and preferably 10 minutes. The electrostatic dust removal time can be set to 3-8 hours, and can also be set according to the pollution degree and the specific requirements.
