3、Advantages of Catalytic reduction denitrification principle
Catalytic reduction denitrificationin the course of 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 can be used in coal-fired power station, building materials, cement plant, metallurgy, coal-fired power station and other industries,It has a wide range of uses, including Improve product quality, Improve product quality, environmental protection, Flue gas denitrification and Meet the requirements of environmental protection,the product looks beautiful.,multifunctional, with functions such as environmental protection, Improve energy efficiency, Improve working conditions, environmental protection and Improve working conditions。

5、Introduction of advantages of Catalytic reduction denitrification
Catalytic reduction denitrifications have the following advantages.
- Intelligent control and convenience of operation
- Diversity and high efficiency of catalysts
- Environmental friendliness
- Wide applicability
- economic viability
The Catalytic reduction denitrification has gradually realized intelligent control. By integrating advanced control system and sensor technology, the 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.
There are many kinds of catalysts used in the Catalytic reduction denitrification technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at low 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 Catalytic reduction denitrification technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.
The by-products produced by Catalytic reduction denitrification 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 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.
Catalytic reduction denitrification 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 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.
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 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, Catalytic reduction denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.

6、Catalytic reduction denitrification structure composition
The Catalytic reduction denitrification has the following structure
- Reactor
- Reducing agent supply
- control system
- Temperature control and monitoring system
- Flue gas mixing and distribution system
It is the core component of Catalytic reduction denitrification technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.
Reducing agents such as liquid pure ammonia or ammonia water (aqueous solution of ammonia) are evaporated and mixed with diluted air or flue gas.
The whole Catalytic reduction denitrification is automatically controlled to ensure the stable operation of the system and achieve the expected denitration effect.
It is used to monitor and control the temperature of the reactor to ensure that the chemical reaction is carried out in the optimal temperature range.
Ensure that the flue gas and reducing agent are fully mixed in the reactor to improve the denitrification efficiency.
Catalytic reduction denitrification
Catalytic reduction 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.,is a Catalytic reduction denitrification。
