High efficiency denitration equipment

Abstract

The invention provides high efficiency denitration equipment. The flue gas flow enters the bottom of a denitrator tank, then slowly diffuses upwards from the bottom of a spiral air duct since the spiral air duct is vertically arranged, is continuously in contacted with a denitration catalyst plate through holes in a diffusion process so as to be subjected to catalytic purification, and is finallydischarged out from a gas outlet. The flue gas flow slowly diffuses upwards from the bottom upwards along the vertically arranged spiral air channel and is in contacted with the denitration catalyst plate through the holes in the diffusion process so as to be subjected to catalytic purification. The spiral air duct can increase a reaction path and diffusion time, and can effectively improve the denitration effect.

Description

technical field [0001] The invention relates to the technical field of gas denitration, in particular to a high-efficiency denitration equipment. Background technique [0002] Coal-fired heating boiler is the most commonly used boiler, which has the advantages of economy and benefits. For urban-rural fringe areas and vast rural areas without central heating and gas heating conditions, coal-fired heating boilers with lower heating costs is ideal. During the combustion process of coal, in addition to producing a large amount of smoke and dust, it will also form pollutants such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, organic compounds and smoke dust, which will be directly discharged into the environment without purification and chemically react with moisture in the air , forming acid rain and seriously polluting the environment. [0003] The existing flue gas denitrification process has the following problems: low removal efficiency, low catalyst...

AI Technical Summary

Problems solved by technology

During the combustion process of coal, in addition to producing a large amount of smoke and dust, it will also form pollutants such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, organic compounds and smoke dust, which will be directly discharged into the environment without purification and chemically react with moisture in the air , forming acid rain and seriously polluting the environment

[0003] The existing flue gas denitrification process has the following problems: low removal efficiency, low catalyst service life, solid waste generation, ammonia escape, high investment cost, large installed capacity of the system, high operating cost, etc.
