Low temperature SCR 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.,It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Low temperature SCR method for denitrification technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.、There are many kinds of catalysts used in the technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at a lower temperature. At the same time, the active components and carrier materials of the catalyst are constantly being developed and improved to improve its catalytic efficiency and service life. This enables the Low temperature SCR method for denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、Technology has been developed and applied for many years, and it is mature and stable. The Low temperature SCR method for denitrification has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Low temperature SCR method for denitrification technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.、There are many kinds of catalysts used in the technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at a lower temperature.

1、Brief introduction of Low temperature SCR method for denitrification

Low temperature SCR method for denitrificationthat is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.,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.,is a Low temperature SCR method for denitrification。
