3、Catalytic reduction low-temperature denitrification equipment application

Catalytic reduction low-temperature denitrification equipmentMainly used forenvironmental protection,Meet the requirements of environmental protection,Promote sustainable development,Improve product quality andMeet the requirements of environmental protection，the 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.，that is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.，The by-products produced by the technology are mainly nitrogen and water vapor, which are harmless to the environment and will not cause secondary pollution.
