3、Low temperature catalyst furnace external denitrification function
Low temperature catalyst furnace external denitrificationit has the functions of Promote sustainable development, Improve energy efficiency, environmental protection, Improve working conditions and Promote sustainable development,The overall structural design is simple and novel.,the main structure includes Flue gas mixing and distribution system, Catalyst reactor, control system, Temperature control and monitoring system, Catalyst supply system and so on,the advantage is 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 Low temperature catalyst furnace external denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Low temperature catalyst furnace external 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 Low temperature catalyst furnace external 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 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 Low temperature catalyst furnace external 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 Low temperature catalyst furnace external 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.,is an efficient, stable and environment-friendly flue gas denitrification technology.,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.。
