What is a Oxidation reduction denitrification system? Introduction to the advantages and characteristics of the SCR denitration system

Oxidation reduction denitrification systemit refers to the process of removing nitrogen oxides from flue gas to reduce environmental pollution. NOx is a pollutant harmful to the atmospheric environment, which has strong irritation and toxicity, and will lead to environmental problems such as acid rain and photochemical smog, and also endanger human health. The main principle of flue gas denitrification technology is to reduce NOx to nitrogen and water by adding appropriate reducing agent or catalyst in the combustion process or flue gas treatment system, so as to reduce NOx emission.。

3、Working principle of Oxidation reduction denitrification system

Oxidation reduction denitrification systemat the start of the operation,Ammonia gas or other suitable reducing agent (such as urea aqueous solution) is sprayed into the flue gas upstream of the catalyst at high temperature. Under the action of catalyst, the reducing agent selectively reacts with nitrogen oxides (NOx) in flue gas to generate pollution-free nitrogen and water vapor. Because NH3 is selective, it only reacts with NOx and basically does not react with O2, so this technology is called selective catalytic reduction denitrification.，delective catalytic reduction technology is an efficient flue gas denitrification technology.。
