What is a Low temperature catalyst flue gas denitrification equipment? Introduction to the principle of SCR denitration system structure

Low temperature catalyst flue gas denitrification equipmentthat is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.，can be customized according to user's needs.。

1、Brief introduction of Low temperature catalyst flue gas denitrification equipment

Low temperature catalyst flue gas denitrification equipmentthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，the main features are Stable operation, Less secondary pollution, Mature and stable technology, High denitration efficiency and Environment friendly，at work,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.。

3、Advantages of Low temperature catalyst flue gas denitrification equipment principle

Low temperature catalyst flue gas denitrification equipmentat 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.，the product looks atmospheric.。
