1、Brief introduction of SCR denitration

SCR denitrationdelective catalytic reduction technology is an efficient flue gas denitrification technology.，the advantage is Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the SCR denitration 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.、Technology has been developed and applied for many years, and it is mature and stable. The SCR denitration has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the SCR denitration technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the SCR denitration 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.、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 SCR denitration technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of SCR denitration technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR denitration technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.，multifunctional, with functions such as Improve energy efficiency, environmental protection, Improve working conditions, Promote sustainable development and Improve energy efficiency，Cheap and high quality。

2、SCR denitration characteristics

The SCR denitration features are as follows:

1. selectivity

Under the action of catalyst, the reducing agent mainly reacts with NOx selectively, but less with other components (such as oxygen) in flue gas, thus reducing unnecessary consumption.

2. Mature technology

After years of development and application, SCR denitration technology is very mature and has a wide application prospect.

3. Small secondary pollution

The by-products produced in the SCR denitration opening process are nitrogen and water vapor, and there is no secondary pollution problem.

4. high efficiency

Gate technology can effectively remove NOx from flue gas, and the denitrification efficiency can usually reach more than 90%.

5. Stable operation and stability

The SCR denitration technology runs stably and can meet the requirements of flue gas treatment under different working conditions.

3、SCR denitration structure

The SCR denitration structure is introduced as follows:

1. Reducing agent supply

Reducing agents such as liquid pure ammonia or ammonia water (aqueous solution of ammonia) are evaporated and mixed with diluted air or flue gas.

2. Temperature control and monitoring

The temperature in the catalyst reactor is maintained within the optimal reaction temperature range through the temperature control and monitoring system.

3. Flue gas mixing and distribution

The mixed reducing agent and flue gas are fully mixed in the mixing tube and evenly distributed to the catalyst reactor through the distribution system.

4. Reducing agent storage and supply system

Used to store and supply reducing agent (such as ammonia or urea solution) to the reactor.

5. Reactor

It is the core component of SCR denitration technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.

5、Working principle of SCR denitration

SCR denitrationat runtime,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 the characteristics of Promote sustainable development, Good selectivity, Environmental protection and pollution-free, Mature and stable technology and energy saving and environmental protection，the product looks atmospheric.，the main structure includes Catalyst reactor, Flue gas mixing and distribution system, Temperature control and monitoring system, control system, Catalyst supply system and so on，SCR denitrationThe structural design is more advanced and reasonable.，it is an ideal choice for customers to buy SCR denitration。

One-combustion energy saving

SCR denitrationusually used in Gas power plant, coal-fired power station, iron and steel plant, metallurgy, building materials and other fields，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.，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 SCR denitration 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 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 SCR denitration 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.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the SCR denitration 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 initial investment of technology may be high, but in the long run, its economic feasibility is remarkable.
