What is a SCR catalyst flue gas denitrification? Introduction to the Working Principle of SCR flue gas denitrification

SCR catalyst flue gas 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.，at 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.，the advantage is The technology is suitable for many industries and processes, such as coal-fired power plants, iron and steel smelting, cement production and so on. These industries will produce a large number of NOx emissions in the production process, and the SCR catalyst flue gas denitrification technology can provide effective denitrification solutions for them. In addition, the gate technology can be adjusted and optimized according to different flue gas components and emission requirements to meet different denitration requirements.、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 SCR catalyst flue gas denitrification 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.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the SCR catalyst flue gas 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.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the SCR catalyst flue gas denitrification can monitor the composition and emission concentration of flue gas in real time, and automatically adjust the injection amount of reductant and the active state of catalyst to ensure the stability and reliability of denitrification efficiency.、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 SCR catalyst flue gas denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.，is designed by One-combustion energy saving with advanced technology。

3、Working principle of SCR catalyst flue gas denitrification

SCR catalyst flue gas denitrificationat runtime,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.，Commonly used inPromote sustainable development,Flue gas denitrification,Improve product quality,environmental protection,Meet the requirements of environmental protection and so on，it has the functions of Improve working conditions, Promote sustainable development, environmental protection, Improve energy efficiency and Improve working conditions，reliable quality，The price is low and affordable。
