Introduction to Roaster tail gas denitrification system and SCR flue gas denitrification structure principle

Roaster tail gas denitrification systemthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.。The following is to introduce the Roaster tail gas denitrification system:

1、Brief introduction of Roaster tail gas denitrification system

Roaster tail gas 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.，Commonly used inenvironmental protection,Promote sustainable development,Improve product quality,Meet the requirements of environmental protection,Flue gas denitrification and so on，The structural design is more advanced and reasonable.，it has the structure of Catalyst supply system, control system, Temperature control and monitoring system, Flue gas mixing and distribution system and Catalyst reactor，Mature and stable technology,Environment friendly,energy saving and environmental protection,Efficient denitration,Strong adaptability，it is an ideal choice for customers to buy Roaster tail gas denitrification system。

3、Roaster tail gas denitrification system structure

The Roaster tail gas denitrification system structure is introduced as follows:

1. control system

The whole Roaster tail gas 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.

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. 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. Reactor

It is the core component of Roaster tail gas denitrification system technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.

5. 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.

5、Roaster tail gas denitrification system principle

Roaster tail gas 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.。

Roaster tail gas denitrification system

Roaster tail gas denitrification systemit has the characteristics of High denitration efficiency, Good selectivity, Promote sustainable development, Stable operation and Stable operation，the main features are Economically feasible, Environmental protection and pollution-free, Strong adaptability, Less secondary pollution and Mature technology，is a kind of high quality and low price Roaster tail gas denitrification system。
