Efficient wet heavy metal removing device of catalytic and oxidation combination of electrostatic precipitator

The invention relates to an efficient wet heavy metal removing device of catalytic and oxidation combination of an electrostatic precipitator. The heavy metal removing device comprises an electrostatic dust removal area (3), a sprinkler area (4), a flue gas inlet (5), a flue gas outlet (12), an ash bucket (8) and a photo-catalytic oxidation area; and the flue gas inlet (5) is formed in the sprinkler area (4), and the electrostatic dust removal area (3) is arranged directly above the sprinkler area (4) and comprises a plurality of positive and negative plates which are distributed in a sequential staggered mode. Compared with the prior art, the heavy metal removing device has the advantages that the multistage removal process of heavy metal particles is adopted, the removal rate is high, anadsorption plate can be automatically washed, and the degree of automation is high. 本发明涉及种高效湿式静电除尘器催化氧化联合脱除重金属装置，所述的脱除重金属装置包括静电除尘区(3)、喷淋区(4)、烟气进口(5)、烟气出口(12)、灰斗(8)和光催化氧化区，所述的烟气进口(5)开设于喷淋区(4)处，所述的静电除尘区(3)设于喷淋区(4)的正上方，其包含多块依次交
