Abstract
The invention discloses a device for removing multiple pollutants at the same time through electrostatic enhanced catalytic oxidation. The device for removing the multiple pollutants at the same time through the electrostatic enhanced catalytic oxidation comprises an electrostatic dust remover(1), an electrostatic enhanced catalytic reaction system (2), a bag-type dust remover (3), a boosting blower (4), an absorbing tower (5) with a circulating slurry pump (6), a draught fan (7) and a chimney (8), wherein flue gas is dedusted by the electrostatic dust remover(1) and enters the electrostatic enhanced catalytic reaction system (2); NOx in the flue gas is removed in the electrostatic enhanced catalytic reaction system (2) and the flue gas enters the bag-type dust remover (3) for further dust removal; the flue gas is boosted by the boosting blower (4) and enters the absorbing tower (5) in which SO2 is removed and the NOx is further removed; and the purified flue gas is exhausted to the chimney (8) by the draught fan (7). The invention also discloses a method for removing the multiple pollutants at the same time by using the device. By the method and the device, the installation cost of a catalyst can be reduced on the premise of ensuring the denitrifying effect.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an electrostatically enhanced catalytic oxidation device and method for simultaneously removing multiple pollutants. Background technique [0002] During the combustion of coal, a large amount of air pollutants such as dust, sulfur dioxide, carbon dioxide, and nitrogen oxides will be emitted. These pollutants have caused serious harm to human health, ecological environment, and social development. SO emissions from coal combustion 2 The amount accounted for the total SO of various pollution sources 2 87% of emissions from coal combustion are NO x Accounting for the total NO of various pollution sources x 67% of emissions. SO from coal burning 2 and NO x Pollution is not only the main problem of air pollution in China, but also an important environmental factor restricting the coordinated and stable economic development. And with the continuous ...
