1、Brief introduction of Steel plant denitrification

Steel plant denitrificationit refers to the process of removing nitrogen oxides from flue gas to reduce environmental pollution. NOx is a pollutant harmful to the atmospheric environment, which has strong irritation and toxicity, and will lead to environmental problems such as acid rain and photochemical smog, and also endanger human health. The main principle of flue gas denitrification technology is to reduce NOx to nitrogen and water by adding appropriate reducing agent or catalyst in the combustion process or flue gas treatment system, so as to reduce NOx emission.，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 Steel plant 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.、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 Steel plant denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Steel plant denitrification 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.、Technology has been developed and applied for many years, and it is mature and stable. The Steel plant denitrification has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Steel plant denitrification technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Steel plant 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.。

3、Introduction of Steel plant denitrification characteristics

Steel plant denitrification has the following characteristics

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. Stable operation and stability

The technology runs stably and reliably, and is suitable for various scenarios with large changes in flue gas flow, composition and concentration.

3. Strong adaptability

Steel plant denitrification technology can meet the needs of flue gas denitrification under different working conditions and has a wide range of applications.

4. Environmental protection

The final products of Steel plant denitrification technology are harmless nitrogen and water vapor, which will not cause secondary pollution to the environment.

5. 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.

5、Steel plant denitrification application

Steel plant denitrificationMainly used forMeet the requirements of environmental protection,environmental protection,Promote sustainable development,Improve product quality andMeet the requirements of environmental protection，at the start of the operation,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 carefully developed by One-combustion energy saving combined with advanced technology。
