Introduction to Low temperature SCR flue gas denitrification system and SCR flue gas denitrification advantages and features

2025-5-27

Low temperature SCR flue 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.,in the course of 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.,Strong adaptability,Good selectivity,Mature and stable technology,Efficient denitration,Strong adaptability,widely used in building materials, Gas power plant, Gas power plant, cement plant, building materials and other fields,is a kind of high quality and low price Low temperature SCR flue gas denitrification system。

2、Working principle of Low temperature SCR flue gas denitrification system

Low temperature SCR flue gas denitrification systemat work,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 overall structural design is relatively simple,it has the structure of Catalyst reactor, control system, Flue gas mixing and distribution system, Temperature control and monitoring system and Catalyst supply system,the product looks atmospheric.,is a Low temperature SCR flue gas denitrification system,features include Mature and stable technology, Promote sustainable development, Stable operation, Good selectivity and energy saving and environmental protection。
