What is a SCR catalytic reduction flue gas denitrification system? Introduction to the Working Principle of SCR denitration

SCR catalytic reduction flue gas 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.，widely used incement plant,Gas power plant,coal-fired power station,building materials,iron and steel plant and other industries，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.，The price is low and affordable，modern technology。The following is to introduce the SCR catalytic reduction flue gas denitrification system:

2、SCR catalytic reduction flue gas denitrification system principle

SCR catalytic reduction flue gas 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.，is a kind of high quality and low price SCR catalytic reduction flue gas denitrification system。
