Dust and white smoke removal device for sintering secondary mixer machine head

Abstract

The invention provides a dust and white smoke removal device for a sintering secondary mixer machine head. The dust and white smoke removal device comprises a supporting steel framework, a dust and water recycling bucket and a white smoke removal box, wherein the supporting steel framework is arranged outside the secondary mixer machine head; the dust and water recycling bucket sleeves a smoke discharge hole of the secondary mixer machine head, and is fixedly connected with the supporting steel framework; the white smoke removal box is in sealing connection to the dust and water recycling bucket; and a damping plate and a smoke gas treatment room are arranged in the white smoke removal box. The dust and white smoke removal device provided by the invention is directly arranged on an equipment smoke outlet position, is small in size, is low in energy consumption, and can directly return treated recycled materials to reutilize. The dust and white smoke removal device solves the emission problem of water vapor discharged by the secondary mixer machine head and solid particulate matters carried in the water vapor, eliminates a white smoke phenomenon of a chimney, and effectively solvesthe air pollution problem.

Description

technical field [0001] The invention relates to the field of environmental protection equipment for iron and steel smelting, in particular to a dust removal and whitening device for the head of a sintering secondary mixer. Background technique [0002] The working order of the sintering secondary mixer in the ironworks is to make pellets and heat the sintered mixture. With the heating process, a large amount of water vapor and dust are generated. Part of the water vapor and dust are mixed and condensed into small droplets, which are discharged to the atmosphere through the chimney. The temperature of the flue gas is low, and the moisture in the saturated wet flue gas condenses into small liquid droplets to form a "white plume", that is, white smoke. A large amount of white smoke containing particulate matter pollutes the environment. The flue gas contains a variety of harmful elements and fine suspended particles, such as sulfur dioxide, hydrogen sulfide and solid particles...

AI Technical Summary

Problems solved by technology

The flue gas contains a variety of harmful elements and fine suspended particles, such as sulfur dioxide, hydrogen sulfide and solid particles, which will cause serious corrosion and rust to the related equipment of the sintering mixer. At the same time, a large number of chloride and oxide particles are suspended in the air. seriously affect air quality

[0003] At present, some enterprises in China use the top chimney and the flue to lead to the lower part through the fan, and use water to spray the steam to condense the steam, but this method consumes too much water, and the effect of this method on steam treatment is not obvious. It just takes most of the heat away from the cooling tower, and there will still be a lot of water mist on the cooling tower

There are also some enterprises that use a professional dust removal and white removal system to process white smoke. The dust removal and white removal system is installed near the secondary mixer, and the white smoke from the exhaust port is introduced into the white smoke removal system through the pipe. Although the white removal system can reduce the emission of solid particles and water vapor and reduce the white feather phenomenon, it cannot completely eliminate the emission of white smoke and solid particles, and the dust removal and whitening equipment occupies a large area and consumes a lot of energy
