Introduction to Oxidation reduction denitrification system, advantages, characteristics and principles of SCR denitration system

Oxidation reduction denitrification systemit 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.，in 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.，multifunctional, with functions such as Promote sustainable development, environmental protection, Improve energy efficiency, Improve working conditions and Promote sustainable development，the main features are Efficient denitration, High denitration efficiency, Strong adaptability, Environment friendly and Economically feasible，it is widely used inmetallurgy,building materials,cement plant,coal-fired power station,metallurgy and other industries。

2、Structural advantages of Oxidation reduction denitrification system

The Oxidation reduction denitrification system 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. 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.

3. 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.

4. control system

The whole Oxidation reduction denitrification system is automatically controlled to ensure the stable operation of the system and achieve the expected denitration effect.

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、Introduction of Oxidation reduction denitrification system characteristics

Oxidation reduction denitrification system has the following characteristics

1. Strong adaptability

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

2. 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.

3. Mature technology

After years of development and application, Oxidation reduction denitrification system technology is very mature and has a wide application prospect.

4. energy saving and environmental protection

This technology can effectively reduce NOx emission in flue gas, reduce environmental pollution, and at the same time, it has stable operation and low energy consumption, which meets the requirements of energy saving and environmental protection.

5. Environmental protection

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

Oxidation reduction denitrification systemthe product looks atmospheric.，at 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.。
