3、Denitrification system in the steel industry structure composition

The Denitrification system in the steel industry 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. Catalytic reduction reaction

Under the action of catalyst, the reductant and NOx in flue gas undergo selective catalytic reduction reaction to generate nitrogen and water vapor.

3. Reducing agent storage and supply system

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

4. 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.

5. control system

The whole Denitrification system in the steel industry is automatically controlled, including the adjustment of reducing agent supply, flue gas flow and temperature, so as to ensure the stable operation of the system and achieve the expected denitrification effect.

4、Denitrification system in the steel industry principle

Denitrification system in the steel industryCatalysts 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.，is an efficient, stable and environment-friendly flue gas denitrification technology.，it is mainly composed of Temperature control and monitoring system, control system, Flue gas mixing and distribution system, Catalyst reactor and Catalyst supply system，is a popular Denitrification system in the steel industry，be loved by our customers.。

Denitrification system in the steel industryit can be used in metallurgy, building materials, coal-fired power station, cement plant, Gas power plant and other industries，Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Denitrification system in the steel industry 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.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Denitrification system in the steel industry 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.、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 Denitrification system in the steel industry 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 Denitrification system in the steel industry technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Denitrification system in the steel industry 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 Denitrification system in the steel industry technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.。
