Embodiment 1

[0101] Example 1 A treatment method for dioxin-like air pollutants in waste miscellaneous copper smelting flue gas

[0102] The processing device is composed of equipment connected in the following order: primary enhanced combustion furnace 1, secondary enhanced combustion furnace 2, silicon nitride porous ceramic filter 3, countercurrent heat exchange waste heat boiler 4, combined heat pipe heat exchanger 5, filter bag Dust collector 6, desulfurization system 7, activated carbon adsorption tower 8 and induced draft fan 9;

[0103] Described processing method comprises the steps:

[0104] ①. Flue gas enhanced combustion

[0105] The flue gas from the scrap copper smelting furnace first enters the primary intensified combustion furnace 1, and then enters the secondary intensified combustion furnace 2 for intensified combustion; so that the organic combustibles carried in the flue gas continue to fully burn; at the same time, during the smelting process, the Dioxin-like compou...

Abstract

The invention relates to a treatment method of dioxin air pollutants in scrap copper smelting smoke and belongs to waste heat utilization and waste gas treatment methods. The treatment method of the dioxin air pollutants in the scrap copper smelting smoke is characterized in that a treatment device is composed of a primary intensified combustion furnace (1), a secondary intensified combustion furnace (2), a silicon nitride porous ceramic filter (3), a counterflow heat exchange waste heat boiler (4), a combined type heat pipe exchanger (5), a bag dust collector (6), a desulfurization system (7), an active carbon adsorption tower (8) and an induced draft fan (9), and the primary intensified combustion furnace (1), the secondary intensified combustion furnace (2), the silicon nitride porous ceramic filter (3), the counterflow heat exchange waste heat boiler (4), the combined type heat pipe exchanger (5), the bag dust collector (6), the desulfurization system (7), the active carbon adsorption tower (8) and the induced draft fan (9) are connected in sequence; by the adoption of the treatment method of the dioxin air pollutants in the scrap copper smelting smoke, the waste heat recovery efficiency is high, and the (dioxins) air pollutants generated in the scrap copper smelting process can be effectively treated. In treated exhaust tail gas, the item indexes of all air pollutants are lower than the values specified in table 3 of GB 31574-2015. The emission of the dioxin air pollutants is smaller than or equal to 0.1 ngTEQ/m<3>. The recovery rate of smoke waste heat is equal to or higher than 95%.

Description

technical field [0001] The invention relates to a method for treating 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 ore...
