Introduction to Catalytic reduction denitrification system and SCR denitration system structure principle

2025-5-27

Catalytic 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.,is a Catalytic reduction denitrification system。The following is to introduce the Catalytic reduction denitrification system:

1、Brief introduction of Catalytic reduction denitrification system

Catalytic reduction denitrification systemthat is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.,Efficient denitration,Mature and stable technology,High denitration efficiency,Promote sustainable development,Economically feasible,the principle is simple.Under the action of catalyst, reducing agents (such as ammonia, urea, etc.) react with nitrogen oxides in flue gas to convert them into harmless nitrogen and water vapor.,is carefully developed by One-combustion energy saving combined with advanced technology。

2、Working principle of Catalytic reduction denitrification system

Catalytic reduction denitrification systemthe principle is simple.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.。

3、Advantages of Catalytic reduction denitrification system principle

Catalytic reduction denitrification systemat the start of the operation,Catalysts are used to promote the selective catalytic reduction reaction between reducing agents (such as ammonia and urea) and NOx in flue gas. Under the action of catalyst, the reductant preferentially reacts with NOx to generate harmless nitrogen and water vapor, but hardly reacts with oxygen in flue gas. This chemical reaction is usually carried out in the temperature range of 200-450℃, and the specific reaction temperature depends on the type of catalyst selected.,reliable quality,low in price。
