Treatment device for non-ferrous metal smelting exhaust gas

Abstract

The invention discloses a treatment device for non-ferrous metal smelting exhaust gas and relates to the technical field of non-ferrous metals. The treatment device comprises an afterheat recovery tank, wherein a vulcanization column is arranged at one side of the afterheat recovery tank, a first pipeline is mounted at a joint of the afterheat recovery tank and the vulcanization column, an electrostatic dust collection box is mounted at one side of the vulcanization column, a second pipeline is mounted at a joint of the vulcanization column and the electrostatic dust collection box, and an activated charcoal adsorption box is arranged at one side of the electrostatic dust collection box. According to the treatment device, the structure is reasonable, and the cost is relatively low; throughthe arranged afterheat recovery tank, afterheat of flue gas can be recycled; through the arranged vulcanization column, sulfur dioxide can be effectively removed from the flue gas to achieve the aimof exhaust gas desulfurization; through the arranged electrostatic dust collection box, dust and solid particles can be effectively removed from the flue gas to achieve the work of dust collection; and through the arranged activated charcoal adsorption box, the exhaust gas is further subjected to purifying treatment, the purification effect of the exhaust gas is improved, and the energy-saving andenvironment-friendly effects are remarkable.

Description

technical field [0001] The invention relates to the technical field of nonferrous metals, in particular to a nonferrous metal smelting waste gas treatment device. Background technique [0002] Non-ferrous metals refer to the general term for all metals except ferrous metals composed of iron, manganese and chromium. Compared with ferrous metals, it has special properties such as corrosion resistance, wear resistance, electrical conductivity, thermal conductivity, toughness, high strength, radioactivity, ductility, plasticity, compressibility and rolling properties. It is an indispensable and important material for the development of modern industry, modern national defense and modern science and technology. During the smelting process of non-ferrous metals, a large amount of waste gas, waste water and waste residue will be produced, and these products will pollute the environment very seriously. [0003] At present, the non-ferrous metal smelting waste gas treatment devices...
