What is a Catalytic denitrification system? SCR denitration system specifications, models, and parameters

Catalytic 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.，the main structure includes Catalyst supply system, control system, Flue gas mixing and distribution system, Temperature control and monitoring system, Catalyst reactor and so on，productThe overall structural design is simple and novel.，is a Catalytic denitrification system。

4、Working principle of Catalytic denitrification system

Catalytic denitrification systemat 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.。

5、Catalytic denitrification system performance advantage

Catalytic denitrification systems have the following advantages.

1. Environmental friendliness

The by-products produced by Catalytic denitrification system technology are mainly nitrogen and water vapor, which are harmless to the environment and will not cause secondary pollution. Compared with the traditional wet flue gas denitrification technology, the Catalytic denitrification system technology does not need to use a lot of water resources and will not produce pollutants such as wastewater, which is more in line with the requirements of environmental protection and sustainable development.

2. Diversity and high efficiency of catalysts

There are many kinds of catalysts used in the Catalytic denitrification system technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at low temperature. At the same time, the active components and carrier materials of the catalyst are constantly being developed and improved to improve its catalytic efficiency and service life. This enables the Catalytic denitrification system technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.

Catalytic denitrification systemCatalysts 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.，delective catalytic reduction technology is an efficient flue gas denitrification technology.。
