What is a Roaster tail gas denitrification system? Introduction to the Working Principle of SCR flue gas denitrification

Roaster tail gas denitrification systemis an efficient, stable and environment-friendly flue gas denitrification technology.。

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.，it has the functions of Promote sustainable development, Improve energy efficiency, Improve working conditions, environmental protection and Improve energy efficiency，the principle is simple.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.，support customization。

3、Advantages of 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.。

4、Roaster tail gas denitrification system structure

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

1. 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.

2. Reducing agent storage and supply system

Used to store and supply reducing agent (such as ammonia or urea solution) to the reactor.

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. 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.
