Introduction to Low temperature SCR denitrification system, introduction to SCR denitration advantages and characteristics

Low temperature SCR 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.，it is widely used incement plant,building materials,cement plant,coal-fired power station,metallurgy and other industries，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 denitrification system 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.、Technology has been developed and applied for many years, and it is mature and stable. The Low temperature SCR denitrification system has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Low temperature SCR denitrification system 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. 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 denitrification system technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、The by-products produced by the technology are mainly nitrogen and water vapor, which are harmless to the environment and will not cause secondary pollution. Compared with the traditional wet flue gas denitrification technology, the Low temperature SCR denitrification system technology does not need to use a lot of water resources and will not produce pollutants such as wastewater, which is more in line with the requirements of environmental protection and sustainable development.、Technology has been developed and applied for many years, and it is mature and stable. The Low temperature SCR denitrification system has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Low temperature SCR denitrification system technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.，in 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 is an ideal choice for customers to buy Low temperature SCR denitrification system。
