  • Patent number: 7833324
    Abstract: A wet electrostatic precipitator is disclosed to include a condensation-growth chamber, a precipitation chamber connecting with the condensation-growth chamber, three dual-sleeve members mounted in the precipitation chamber, three discharge electrodes connecting with the dual-sleeve members, two insulating members covering on the inner surface of the precipitation chamber, and two ground electrodes mounted on the outside of the precipitation chamber. Thus, a uniform water film is formed on the surface of the insulating members to wash away the particles from waste gas. The condensation-growth chamber is provided for the particles to grow therein and thereby enhances the collection efficiency. The insulating member acts as a shield between the discharge electrodes and the ground electrodes and thereby avoids a short circuit or sparks.
