2、Advantages of SCR oxidation denitrification system principle

SCR oxidation denitrification systemthe principle is simple.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 has the structure of Catalyst supply system, Catalyst reactor, Temperature control and monitoring system, Flue gas mixing and distribution system and control system,This productThe overall structural design is relatively simple and compact.。

SCR oxidation denitrification system

SCR oxidation denitrification systemit is widely used in coal-fired power station, building materials, Gas power plant, cement plant and cement plant,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 oxidation denitrification system 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.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the SCR oxidation 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 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 oxidation 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 SCR oxidation denitrification system has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the SCR oxidation denitrification system technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission 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 SCR oxidation 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 oxidation denitrification system technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.,the main features are energy saving and environmental protection, Promote sustainable development, Environmental protection and pollution-free, Stable operation and Strong adaptability。
