What is a SCR catalytic reduction method for denitrification? Introduction to the principle of SCR denitration structure

SCR catalytic reduction method for denitrificationthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，at 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.，the main features are Strong adaptability, Economically feasible, energy saving and environmental protection, Promote sustainable development and Mature and stable technology，widely used in metallurgy, cement plant, Gas power plant, building materials, metallurgy and other fields，it has the characteristics of Environmental protection and pollution-free, Strong adaptability, Environment friendly, Less secondary pollution and Good selectivity。

1、Brief introduction of SCR catalytic reduction method for denitrification

SCR catalytic reduction method for denitrificationit 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.。
