2、Introduction of advantages of SCR low temperature flue gas denitrification equipment

The advantages of SCR low temperature flue gas denitrification equipment are as follows:

1. High efficiency denitration capacity

Gate is famous for its high efficiency of denitration, which can usually reach more than 90% denitration efficiency. This means that the SCR low temperature flue gas denitrification equipment 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 mainly benefits from the promotion of catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.

2. Intelligent control and convenience of operation

The SCR low temperature flue gas denitrification equipment has gradually realized intelligent control. By integrating advanced control system and sensor technology, the SCR low temperature flue gas denitrification equipment 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.

3. economic viability

The initial investment of this technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of SCR low temperature flue gas denitrification equipment 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 equipment technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.

4. Wide applicability

SCR low temperature flue gas denitrification equipment 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 SCR low temperature flue gas denitrification equipment 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.

5. Environmental friendliness

The by-products produced by SCR low temperature flue gas denitrification equipment 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 SCR low temperature flue gas denitrification equipment 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.

4、SCR low temperature flue gas denitrification equipment principle

SCR low temperature flue gas denitrification equipmentat work,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.，it has been widely used in metallurgy, building materials, coal-fired power station, cement plant, Gas power plant and other industries，it is an ideal choice for customers to buy SCR low temperature flue gas denitrification equipment。

5、SCR low temperature flue gas denitrification equipment function

SCR low temperature flue gas denitrification equipmentmultifunctional, with functions such as Promote sustainable development, Improve working conditions, Improve energy efficiency, Promote sustainable development and environmental protection，The structural design is simple, novel and special.，the main structure includes Catalyst reactor, control system, Flue gas mixing and distribution system, Temperature control and monitoring system, Catalyst supply system and so on，in 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. 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.，is a popular SCR low temperature flue gas denitrification equipment，support customization。
