Introduction to Low temperature absorption SCR denitrification equipment and SCR flue gas denitrification advantages and features

Low temperature absorption SCR denitrification equipmentthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，super quality and competitive price。

1、Brief introduction of Low temperature absorption SCR denitrification equipment

Low temperature absorption SCR denitrification equipmentis an efficient, stable and environment-friendly flue gas denitrification technology.，it has the characteristics of Environment friendly, Environmental protection and pollution-free, Less secondary pollution, Good selectivity and Economically feasible，the product looks atmospheric.，multifunctional, with functions such as Improve working conditions, environmental protection, Improve energy efficiency, Promote sustainable development and Improve working conditions，at runtime,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.。

2、Structural advantages of Low temperature absorption SCR denitrification equipment

The Low temperature absorption SCR denitrification equipment has the following structure

1. control system

The whole Low temperature absorption SCR denitrification equipment 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. 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. Reducing agent storage and supply system

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

4. Reactor

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

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.

4、Advantages of Low temperature absorption SCR denitrification equipment principle

Low temperature absorption SCR denitrification equipmentat the start of the operation,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.，it 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.，is a kind of high quality and low price Low temperature absorption SCR denitrification equipment。
