3、Catalyst reduction denitrification equipment principle

Catalyst reduction denitrification equipmentthe 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.,The overall structural design is relatively simple,it is usually composed of Catalyst reactor, control system, Catalyst supply system, Temperature control and monitoring system and Flue gas mixing and distribution system,usually used in metallurgy, iron and steel plant, Gas power plant, building materials, metallurgy and other fields,Mainly used forFlue gas denitrification,environmental protection,Promote sustainable development,Meet the requirements of environmental protection andenvironmental protection,Simple structure and reliable operation.,it mainly includes Catalyst reactor, control system, Flue gas mixing and distribution system, Temperature control and monitoring system and Catalyst supply system。
