A wet electrostatic precipitator is an efficient atmospheric pollution control device that combines the dual advantages of wet dust removal and electrostatic dust removal, widely used in the flue gas purification process in industries such as power, chemicals, metallurgy, and building materials. Its core principle involves utilizing a high-voltage electric field to ionize the gas, producing a large number of positive and negative ions, which attach to dust particles, making them charged and then collected by the collection electrode, thereby achieving dust removal. Additionally, the wet design further enhances the collection efficiency of fine particles, aerosols, and heavy metals through spray mist or recirculating water systems, particularly suitable for treating flue gas environments with high temperature, high humidity, or corrosive gases.
