Introduction to SCR flue gas catalytic denitrification system and SCR denitration system advantages and features

SCR flue gas catalytic denitrification systemdelective catalytic reduction technology is an efficient flue gas denitrification technology.，is a SCR flue gas catalytic denitrification system，it is widely used in iron and steel plant, cement plant, building materials, metallurgy and cement plant，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.，Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the SCR flue gas catalytic denitrification system 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.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the SCR flue gas catalytic 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.、The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of SCR flue gas catalytic denitrification system technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR flue gas catalytic denitrification system technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、Technology has been developed and applied for many years, and it is mature and stable. The SCR flue gas catalytic denitrification system has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the SCR flue gas catalytic denitrification system technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission 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 flue gas catalytic 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.。
