It is mainly used to remove dust, acid mist, water droplets, aerosols, odor, PM2.5 and other harmful substances in wet gas. It is an ideal equipment for controlling atmospheric dust pollution. The basic dust removal principle of flue gas wet electrostatic precipitator is the same as that of dry electrostatic precipitator, which has to go through three stages: charging, collection and cleaning.

[0003] The existing flue gas wet electrostatic precipitator charges the dust through high-voltage corona discharge. The charged dust adheres to the dust collecting plate under the action of the electric field force. The dust attached to the dust collecting plate is washed off by water, but the conventional flushing method is not thorough, which affects the dust collection efficiency.

[0004] In view of the above problems, the utility model provides a corrosion-resistant flue gas wet electrostatic precipitator. Utility Model Content
