Problems solved by technology

Although the traditional recycling method does not produce large secondary pollution, there is still secondary soot with high lead content in the end.
Wet method-pyrochemical comprehensive smelting can recover valuable metals from soot and turn waste into treasure, but the metal recovery rate is low and the profit is meager

Abstract

The invention discloses a treatment system for fumes containing Pb and Zn, and relates to the technical field of copper smelting fume disposal. The processing system for fumes containing Pb and Zn includes a fixed bottom plate, the top of the fixed bottom plate is fixedly connected with a sealing mechanism near the center, the top of the fixed bottom end is fixedly connected with a wind box near the front, and the inner wall of the wind box The provided fixed bottom plate communicates with the inner wall of the sealing mechanism, and the top end of the sealing mechanism is provided with an air outlet near the center, and the inner wall of the air outlet communicates with the inner wall of the sealing mechanism. The Pb and Zn fume treatment system, through the provided sealing mechanism, can convert the gas into a solid inside the sealing mechanism, and then melt the solid, collect the particles in the solid, and effectively remove the particles in the soot Removal is carried out to reduce the pollution of smoke to the environment and increase the environmental protection performance of the device.

Description

technical field [0001] The invention relates to the technical field of copper smelting soot disposal, in particular to a treatment system for fumes containing Pb and Zn. Background technique [0002] In wet smelting, the active metals such as zinc and copper in the soot are sequentially leached with low acid, and then the leached slag is put into the pyrosystem for treatment. Zinc leaching rate is 52%, copper 22%. The fire method system firstly mixes the washed slag and various fluxes in a certain proportion, and then presses the mixture into bricks and puts them into the furnace for smelting to produce crude lead, matte, white matte, secondary soot and water-quenched slag. Crude lead is then fire-refined to produce lead-bismuth alloy, crude tin oxide and scum. Although the traditional recycling method does not produce major secondary pollution, secondary soot with high lead content is still produced in the end. Wet method-pyrochemical comprehensive smelting can recover v...
