Introduction to Low temperature catalytic flue gas denitrification, SCR flue gas denitrification specifications, model parameters

Low temperature catalytic 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.，it is mainly composed of Flue gas mixing and distribution system, Catalyst reactor, Temperature control and monitoring system, control system and Catalyst supply system，productThe overall structural design is relatively simple and compact.，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 catalytic flue gas 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.、Technology has been developed and applied for many years, and it is mature and stable. The Low temperature catalytic flue gas denitrification has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Low temperature catalytic flue gas denitrification technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Low temperature catalytic 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.、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 catalytic flue gas denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、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 catalytic 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.，can be customized according to user's needs.。

1、Brief introduction of Low temperature catalytic flue gas denitrification

Low temperature catalytic flue gas denitrificationthat is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.，is a kind of high quality and low price Low temperature catalytic flue gas denitrification，at the start of the operation,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.，super quality and competitive price。
