1、Brief introduction of Low temperature catalytic reduction denitrification

Low temperature catalytic reduction denitrificationis an efficient, stable and environment-friendly flue gas denitrification technology.，the principle is simple.Catalysts are used to promote the selective catalytic reduction reaction between reducing agents (such as ammonia and urea) and NOx in flue gas. Under the action of catalyst, the reductant preferentially reacts with NOx to generate harmless nitrogen and water vapor, but hardly reacts with oxygen in flue gas. This chemical reaction is usually carried out in the temperature range of 200-450℃, and the specific reaction temperature depends on the type of catalyst selected.，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 Low temperature catalytic reduction 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.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Low temperature catalytic reduction 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.、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 reduction 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 initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Low temperature catalytic reduction denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Low temperature catalytic reduction denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、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 reduction denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.，is a kind of Low temperature catalytic reduction denitrification manufactured by One-combustion energy saving。

3、Advantages of Low temperature catalytic reduction denitrification principle

Low temperature catalytic reduction denitrificationin the course of work,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.
