A wet electrostatic precipitator is an efficient air pollution control device that combines the dual advantages of wet dust removal and electrostatic dust removal, widely used in the flue gas purification processes of power, chemical, metallurgical, and building materials industries. Its core principle lies in utilizing a high-voltage electric field to ionize the gas, producing a large number of positive and negative ions, which attach to dust particles, causing them to become charged and then collected by the electrode, thereby achieving dust removal. Additionally, the wet design further enhances the collection efficiency of fine particles, aerosols, and heavy metals, etc., through spray misting or a recirculating water system, making it particularly suitable for treating flue gas environments with high temperatures, high humidity, or corrosive gases.
