What is a Oxidation reduction flue gas denitrification? SCR flue gas denitrification specifications, models, and parameters

Oxidation reduction 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.，widely used incoal-fired power station,cement plant,iron and steel plant,building materials,coal-fired power station and other industries，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 Oxidation reduction 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.、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 Oxidation reduction flue gas denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Oxidation reduction flue gas denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Oxidation reduction flue gas denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Oxidation reduction 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.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Oxidation reduction 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.。The following is to introduce the Oxidation reduction flue gas denitrification:
