The high-efficiency denitration ability of SCR low temperature 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, SCR low temperature flue gas denitrification 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 low temperature flue gas denitrification has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the SCR low temperature flue gas denitrification technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.、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 low temperature flue gas denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、Intelligent control is gradually realized.

2、Advantages of SCR low temperature flue gas denitrification principle

SCR low temperature flue gas denitrificationthe 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 is mainly composed of control system, Flue gas mixing and distribution system, Temperature control and monitoring system, Catalyst supply system and Catalyst reactor，the product looks beautiful.，super quality and competitive price。
