Disclosed relates to a dioxin removal apparatus, and specifically it relates to a dioxin and particulate removal apparatus and method using a thermal plasma, in which flue gas generated from wastes incineration facilities is completely combusted, and then the flue gas is rapidly cooled by spraying waters to the flue gas to prevent the denovo-synthesis of dioxin r generation of nitrates in the subsequent process and simultaneously various environmental pollutants in the flue gas are washed out. The method of the present invention comprise the steps of a decomposition step of thermo-chemically destroying the flue gas containing dioxin, soot, particulate, and incomplete combustion products, generated from the incineration facility, by using a thermal plasma; a cooling and washing step of rapid cooling the hot flue gas in the decomposition step and simultaneous washing pollutants in the flue gas; a dewatering step of reducing water content in the flue gas cooled in the cooling and washing step; and a wastewater discharging step of discharging cooling water used in the cooling and washing step (200) and in the dewatering step (300). |
