Abstract
The invention relates to a wet-type electrostatic precipitator capable of removing micropollutants efficiently. The wet-type electrostatic precipitator capable of removing micropollutants efficiently, which is provided by the invention, is sequentially provided with dust collecting electrodes, electric discharge electrodes, a spraying master pipe, spraying branch pipes, sprayers, a spraying water tank and a reactant storage box. According to the invention, organic chelating agents in the reactant storage box are added into the spraying water tank, and are sprayed into the wet-type electrostatic precipitator along with water mist, perform chelation reaction with multiple heavy metal ions in a water membrane so as to generate a metal chelate compound which is stable and is water-insoluble, so that trace heavy metal pollutants in flue gas are removed efficiently. The wet-type electrostatic precipitator capable of removing micropollutants efficiently, which is provided by the invention, is low in running resistance; water mist sprayed by the sprayers bidirectionally directly covers the dust collecting electrodes at two sides of the sprayers, and the water spraying efficiency is high; the formed water membrane is good in uniformity; and the efficiency of removing the micropollutants is high.
