Industrial waste gas denitration process

Abstract

The invention relates to the technical field of industrial waste gas treatment, discloses an industrial waste gas denitration process, and aims to solve the problems that nitric oxide and nitrogen dioxide cannot be effectively reacted during industrial waste gas treatment, heat loss can be generated in the process to cause resource waste, the degree of denitration reaction cannot be confirmed, and discharged waste gas does not reach the standard. According to the invention, industrial waste gas with a relatively low temperature is heated through a heating device, and the industrial waste gas is adaptive to the temperature required to be reached by a denitration reaction and is slightly higher than the minimum value of the optimal temperature, so that certain energy loss can be generated in a reasonable condition in a conveying process of the heated waste gas; the waste gas can be heated to reach the optimal temperature of a denitration reaction, a urea solution can be prepared, a reducing agent can be conveniently and quantitatively reacted with the waste gas, the exhausted waste gas can be detected, further reaction can be carried out to reach the emission standard, heat can be recycled, and resources can be utilized to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas treatment, in particular to an industrial waste gas denitrification process. Background technique [0002] In the process of industrial production, more exhaust gas is often produced. There will be more nitrogen monoxide and nitrogen dioxide in the exhaust gas, accompanied by more dust. If it is not treated and discharged, it will cause serious damage to the air. Pollution can also affect the health of workers. [0003] In the treatment of industrial waste gas, it is often impossible to effectively react to nitrogen monoxide and nitrogen dioxide, and heat loss will be generated in the process, resulting in waste of resources. The degree of denitrification reaction cannot be confirmed, so that the exhaust gas emission is not up to standard. In view of this situation, those skilled in the art provide an industrial waste gas denitrification process. Contents of the invention [0004]...
