Atmospheric pollution prevention and control device for chemical flue gas

Abstract

The invention discloses an atmospheric pollution prevention and control device for chemical flue gas. The device comprises a box body, a flue gas inlet pipe and an exhaust pipe, the flue gas inlet pipe is arranged on the left side of the box body, the flue gas inlet pipe penetrates through the side wall of the box body and is connected to a first filter box in the box body, a first filter screen is installed in the first filter box, the right side of the first filter box is connected with a cooling box through a first rectangular pipeline, and the right side of the cooling box is connected with a second filter box through a second rectangular pipeline. According to the invention, flue gas is preliminarily filtered through the first filter screen, the cooling box cools the flue gas, the second filter screen finely filters the flue gas, the chemical reaction treatment box absorbs and decomposes harmful substances in the flue gas, and the solenoid valve, the second sucking pump, the thirdconnecting pipe and the second connecting pipe are matched to carry out secondary chemical reaction treatment on the flue gas which does not reach the standard, therefore, the flue gas is fully purified, pollution control is carried out, and the treatment effect is good.

Description

Technical field [0001] The invention relates to the technical field of air pollution prevention and control, in particular to an air pollution prevention and control device for chemical flue gas. Background technique [0002] Air pollution prevention and control is mainly to control the problem of air pollution. There are many factors in air pollution, including automobile exhaust emissions, chemical flue gas emissions and flue gas emissions from some thermal power plants. If not treated in time, it will cause serious pollution to the atmosphere. For example, now Common haze is extremely harmful to human health and can induce many cancers. [0003] The existing chemical flue gas treatment is mainly to simply filter the flue gas. Some toxic and harmful substances are not filtered or not thoroughly filtered, and the emitted flue gas includes a large amount of dust, which causes a significant increase in particulate matter in the air. Moreover, the dust temperature is relatively high...

AI Technical Summary

Problems solved by technology

[0003] The existing chemical flue gas treatment is mainly to do a simple filtering process for the flue gas. Some toxic and harmful substances have not been filtered or the filtration is not thorough enough, and the exhausted flue gas contains a large amount of dust, resulting in a significant increase in particulate matter in the air. Moreover, the temperature of these dusts is relatively high, which poses a serious threat to the natural environment near the factory.
