[0002] As a highly efficient air purification device, wet electrostatic precipitator plays an important role in industrial dust removal, flue gas purification and other fields. Its working principle is mainly based on the effect of electric field. By spraying water mist into the dust collector, the dust particles in the air are moistened and charged, and then captured on the dust collecting plate under the action of the electric field force, thereby achieving the purpose of dust removal. However, the existing wet electrostatic precipitator technical solution still has some significant shortcomings, which limits its further performance improvement and wide application.
