Introduction to Catalytic reduction low-temperature denitrification, advantages, characteristics and principles of SCR denitration

Catalytic reduction low-temperature denitrificationit 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 characteristics of Less secondary pollution, Strong adaptability, energy saving and environmental protection, Stable operation and Mature technology。The following is to introduce the Catalytic reduction low-temperature denitrification:

1、Brief introduction of Catalytic reduction low-temperature denitrification

Catalytic reduction low-temperature denitrificationthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，it can be used in cement plant, coal-fired power station, Gas power plant, iron and steel plant, building materials and other industries，be of high quality。

2、Structural characteristics of Catalytic reduction low-temperature denitrification

The Catalytic reduction low-temperature denitrification structure is introduced as follows:

1. Reducing agent storage and supply system

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

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. Reactor

It is the core component of Catalytic reduction low-temperature denitrification technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.

4. Flue gas mixing and distribution system

Ensure that the flue gas and reducing agent are fully mixed in the reactor to improve the denitrification efficiency.

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.

Catalytic reduction low-temperature denitrificationIt can be used for environmental protection, Improve product quality, Meet the requirements of environmental protection, Promote sustainable development, Flue gas denitrification, environmental protection and so on，widely used inmetallurgy,coal-fired power station,Gas power plant,iron and steel plant,cement plant and other industries，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.。
