1、Brief introduction of SCR low-temperature denitrification

SCR low-temperature 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.,is a common SCR low-temperature denitrification,support customization。

2、Advantages of SCR low-temperature denitrification principle

SCR low-temperature denitrificationin the course of work,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.,It can be used for Promote sustainable development, Meet the requirements of environmental protection, Flue gas denitrification, Meet the requirements of environmental protection, Promote sustainable development, Flue gas denitrification and so on,generally, it is composed of Flue gas mixing and distribution system, Temperature control and monitoring system, Catalyst supply system, Catalyst reactor, control system and other major components,productThe structural design is more advanced and reasonable.,is a kind of high quality and low price SCR low-temperature denitrification,it is an ideal choice for customers to buy SCR low-temperature denitrification。
