White smoke removing apparatus used for non-ferrous metal processing and convenient for flue gas recovery

Abstract

The invention discloses a white smoke removing apparatus used for non-ferrous metal processing and convenient for flue gas recovery. The white smoke removing apparatus comprises a white smoke removingkettle, a pressure pump, a positioning ring and a high-pressure electrostatic device, wherein a positioning vertical pipe is fixedly mounted at the vertical central position of the white smoke removing kettle; return pipes are connected to a flow diversion pipe and the outer wall of the bottom of the white smoke removing kettle; a rotating ring and a sliding sleeve are sequentially arranged on the outer wall of the positioning vertical pipe from top to bottom; a bearing is fixed between the positioning vertical pipe and the rotating ring; a connecting rod is vertically fixed to the outer wallof the positioning vertical pipe; the positioning ring is fixedly installed on the inner wall of the white smoke removing kettle; a wire support is fixed to the top of a vertical pipe support; an ashdischarging valve is installed at an outlet in the bottom of the white smoke removing kettle; and a filter screen is arranged in a demister. The white smoke removing apparatus used for non-ferrous metal processing and convenient for flue gas recovery can perform quick white smoke removal operation on soot, fog drops and the like in flue gas, is simple and efficient in structure, reduced in working energy consumption, and avoids effective substance emission caused by low flue gas reaction during white smoke removal of metal.

Description

technical field [0001] The invention relates to the technical field of nonferrous metal dewhitening, in particular to a nonferrous metal dewhitening device that facilitates flue gas recovery. Background technique [0002] During the processing and production of non-ferrous metals, the combustion reaction between its chemical components will produce a large amount of dark white smoke, which contains a large number of harmful by-products, which will bring serious safety hazards to the environment and human health. Therefore, in non-ferrous metals During metal production, the harmful substances in the by-products need to be fully recovered and dewhitened by flue gas, so that the content of harmful substances in the dewhitened flue gas can meet the emission standards and protect the environment and sanitation. [0003] Yet existing nonferrous metal dewhitening device has the following problems in use: [0004] 1. Continuous and uninterrupted flue gas recovery and dewhitening is...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a non-ferrous metal dewhitening device that is convenient for flue gas recovery, so as to solve the above-mentioned background technology. Excessive content of harmful substances in the gas causes insufficient flue gas recovery, which makes the efficiency of flue gas recovery and dewhitening low. The flue gas in the dewhitening kettle is rich and has few distribution gaps, and the dewhitening reaction cannot be carried out quickly and effectively. At the same time, it is inconvenient to clean the dust on the inner wall of the de-whitening kettle after de-whitening, and at the same time, the overall cost of the device is high, and the energy consumption is large.
