What is a SCR medium temperature denitrification system? Introduction to the advantages and characteristics of the SCR denitration

SCR medium temperature 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.，the product looks beautiful.。

3、Advantages of SCR medium temperature denitrification system principle

SCR medium temperature denitrification systemCatalysts 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.，delective catalytic reduction technology is an efficient flue gas denitrification technology.，favorable price。

4、Structural characteristics of SCR medium temperature denitrification system

The SCR medium temperature 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. control system

The whole SCR medium temperature denitrification system 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. 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.

4. 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.

5. Reactor

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

One-combustion energy saving

SCR medium temperature denitrification systemis a SCR medium temperature denitrification system，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.，it mainly includes Catalyst supply system, Catalyst reactor, control system, Flue gas mixing and distribution system and Temperature control and monitoring system。
