Wet electrostatic precipitators are widely used in various industries such as large plastic granulation processing, waste incineration, electroplating plant acid mist, molding machine smoke, quenching furnaces, tempering furnaces, large-scale casting, rubber cracking exhaust gas, thick smoke treatment, tar treatment, and water mist treatment. These precipitators use water spray or overflow water to form a water film on the surface of the dust collection electrodes, achieving electrostatic dust removal on the electrode plates. Wet cleaning prevents the resuspension of settled dust, achieving high dust removal efficiency. They are free of impact devices and operate stably.
