What is a Catalytic denitrification? Introduction to the advantages and characteristics of the SCR denitration

Catalytic 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.，the advantage is It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Catalytic 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 Catalytic 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.、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 Catalytic 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.、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 Catalytic 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 initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Catalytic denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Catalytic denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.，at 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.，generally, it is composed of Flue gas mixing and distribution system, Temperature control and monitoring system, Catalyst reactor, Catalyst supply system, control system and other major components，This productThe overall structural design is simple, diverse and beautiful.，It can be used for Improve product quality, Flue gas denitrification, Meet the requirements of environmental protection, Promote sustainable development, environmental protection, Flue gas denitrification and so on。
