1、Brief introduction of Steel plant denitrification

Steel plant denitrificationthat is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.，is carefully developed by One-combustion energy saving combined with advanced technology。

2、Working principle of Steel plant denitrification

Steel plant denitrificationAmmonia 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.，it has the functions of Promote sustainable development, Improve energy efficiency, environmental protection, Improve working conditions and Promote sustainable development，the full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.。

4、Steel plant denitrification structure composition

The Steel plant denitrification has the following structure

1. 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.

2. control system

The whole Steel plant denitrification 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.

3. 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.

4. Reactor

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

5. 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.

5、Steel plant denitrification application

Steel plant denitrificationMainly used forFlue gas denitrification,Improve product quality,environmental protection,Meet the requirements of environmental protection andPromote sustainable development，The overall structural design is relatively simple，it is mainly composed of Catalyst supply system, Temperature control and monitoring system, Flue gas mixing and distribution system, Catalyst reactor and control system，delective catalytic reduction technology is an efficient flue gas denitrification technology.，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 Steel plant 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.、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.、The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Steel plant denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Steel plant denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、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.、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.，is a kind of high quality and low price Steel plant denitrification。
