A wet-type 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, chemical, metallurgy, and building materials. Its core principle is to use a high-voltage electric field to ionize the gas, producing a large number of positive and negative ions. These ions attach to dust particles, causing them to become electrically charged and then collected by the electrodes, thereby achieving dust removal. Additionally, the wet design, through the use of spray mist or a recirculating water system, further enhances the collection efficiency of fine particles, aerosols, and heavy metals, making it particularly suitable for treating flue gas environments that are high in temperature, humidity, or contain corrosive gases.
