Working principle of wet electrostatic precipitator
Under the action of high DC voltage ①, the metal discharge wire ionizes the surrounding gas ② and charges the surface of the dust or mist droplet particles ③. The charged particles move toward the dust collection pole under the action of the electric field force ④ and are deposited on the collector. On the dust pole ⑤, the water flow flows down from the top of the dust collecting plate, forming a uniform and stable water film ⑥ on the dust collecting plate, taking away the particles on the board ⑦
Therefore, the dust removal principles of wet electrostatic precipitators and dry ESPs are basically the same. They both go through three stages of charging, collection and dust cleaning. The biggest difference lies in the different dust cleaning methods. Wet electrostatic precipitators use liquid to flush the dust collector. Clean the surface.
