Abstract

The invention provides a treatment device for dioxin atmospheric pollutants in scrap copper smelting flue gas, and belongs to the method of waste heat utilization and waste gas treatment. The treatment device is characterized by consisting of the following equipment which are sequentially connected: a primary enhanced combustion furnace (1), a secondary enhanced combustion furnace (2), a silicon nitride porous ceramic filter (3), a countercurrent heat exchange waste heat boiler (4), a combined type heat pipe heat exchanger (5), a filter bag dust remover (6), a desulfurization system (7), an active carbon adsorption tower (8) and an induced draught fan (9). The invention provides the treatment device for dioxin atmospheric pollutants in scrap copper smelting flue gas, and the treatment device is high in waste heat recovery efficiency, and is capable of effectively treating the dioxin atmospheric pollutants generated in the scrap copper smelting process; in the treated exhausted tail gas, all item pollutants of the atmospheric pollutants are lower than a limiting value defined in GB31574-2015 table 3; and the discharge amount of the dioxin atmospheric pollutants is lower than or equal to 0.1ngTEQ / m<3>, and the flue gas waste heat recovery rate is higher than or equal to 95%.

Description

technical field [0001] The invention relates to a treatment device for dioxin-like air pollutants in waste miscellaneous copper smelting flue gas. It belongs to the method of waste heat utilization and waste gas treatment. Background technique [0002] Copper is a kind of non-ferrous metal and one of the earliest metals used by human beings. Because copper metal has excellent characteristics such as good electrical conductivity, heat transfer, ductility, high strength and good corrosion resistance, it has a wide range of uses, and its market consumption is second only to iron and aluminum, ranking third in metal consumption. Copper and copper alloys occupy an important position in the development of the national economy. It is an indispensable and important metal material in construction engineering, transportation, machinery manufacturing, power transmission, electronic appliances, automobile industry, national defense industry, and aerospace industry. [0003] Copper or...
