The utility model relates to a tail -gas clean -up field, concretely relates to sintering tail gas cleanup unit of iron ball group. Tail gas cleanup unit includes spray column (1), cooling tower (2), electric demister (3), AO reaction tower (4) and the tower of absorb the remnant air (8), spray column (1), cooling tower (2), electric demister (3), AO reaction tower (4) and the tower of absorb the remnant air (8) end to end in proper order, AO reaction tower (4) in set gradually once absorbed layer, second absorption layer and active catalysis layer from the bottom to the top. Be applied to the utility model discloses a tail gas cleanup unit and purification techniques can reach harmful impurity such as SO2 in the desorption flue gas, NOx, dirt, fluorine, chlorine, realize gas cleaning, can retrieve SO2 again. The device has a multiple pollutant of desorption simultaneously, but continuous production effective recycling sulphur resource, the characteristics that adaptability is wide have extensive using value. |
