The invention discloses a flue gas treatment device and method, namely an integrated flue gas desulfurization, denitrification, demercuration, dedusting and defogging device and method. The device comprises flue gas treatment equipment, ozone supply equipment, hydrogen peroxide supply equipment and the like, wherein the flue gas treatment equipment comprises an ozone spray oxidation reaction layer, a hydrogen peroxide spray oxidation reaction layer, an absorbing sprinkling area, a slurry storage area and a dedusting and defogging area; both the ozone spray oxidation reaction layer and the hydrogen peroxide spray oxidation reaction layer are arranged in the absorbing sprinkling area; the dedusting and defogging area is positioned above the absorbing sprinkling area. The device and the method provided by the invention are suitable for integrated desulfurization, denitrification, demercuration, dedusting and defogging treatment of flue gas which contains SO2, NOX, Hg<0> and dust, and is produced by coal burning boilers, steel sintering machines, pellets, industrial furnaces and the like, and can solve the problem that a conventional process is complex in equipment, high in running cost and energy consumption, and low in demercuration and denitration efficiencies. |
