Device for synergistically removing NOx, CO and dioxin

The utility model relates to a sintering machine flue gas treatment technology in the iron and steel industry, in particular to equipment for synergistically removing NOx, CO and dioxin. The device for synergistically removing NOx, CO and dioxin comprises a reaction tower, the top of the reaction tower is connected with a flue gas inlet pipe, and the bottom of the reaction tower is connected with a flue gas discharge pipe. A plurality of first honeycomb catalyst fillers for removing NOx and at least one second honeycomb catalyst filler for removing CO and dioxin are sequentially arranged in the reaction tower at intervals from top to bottom. The device has the advantages that CO and dioxin can be synergistically removed while NOx is removed, multi-pollution up-to-standard emission can be realized, meanwhile, the ammonia escape value is reduced, the treatment process flow of the whole device is reduced, and the occupied area is reduced; the process is simple and convenient to operate; pollutant emission is red
