1、Brief introduction of Low temperature catalyst denitrification

Low temperature catalyst denitrificationthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，it can be used in iron and steel plant, building materials, Gas power plant, Gas power plant, coal-fired power station and other industries，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.。

2、Introduction of advantages of Low temperature catalyst denitrification

Low temperature catalyst denitrifications have the following advantages.

1. Environmental friendliness

The by-products produced by Low temperature catalyst denitrification 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 Low temperature catalyst denitrification 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. High efficiency denitration capacity

Gate is famous for its high efficiency of denitration, which can usually reach more than 90% denitration efficiency. This means that the Low temperature catalyst denitrification technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability mainly benefits from the promotion of catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.

3. Diversity and high efficiency of catalysts

There are many kinds of catalysts used in the Low temperature catalyst denitrification 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 Low temperature catalyst denitrification technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.

4. Wide applicability

Low temperature catalyst denitrification technology is suitable for many industries and processes, such as coal-fired power plants, iron and steel smelting, cement production and so on. These industries will produce a large number of NOx emissions in the production process, and the Low temperature catalyst denitrification technology can provide effective denitrification solutions for them. In addition, the gate technology can be adjusted and optimized according to different flue gas components and emission requirements to meet different denitration requirements.

5. Intelligent control and convenience of operation

The Low temperature catalyst denitrification has gradually realized intelligent control. By integrating advanced control system and sensor technology, the Low temperature catalyst denitrification can monitor the composition and emission concentration of flue gas in real time, and automatically adjust the injection amount of reductant and the active state of catalyst to ensure the stability and reliability of denitrification efficiency.

4、Advantages of Low temperature catalyst denitrification principle

Low temperature catalyst denitrificationat 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.，delective catalytic reduction technology is an efficient flue gas denitrification technology.，is carefully developed by One-combustion energy saving combined with advanced technology。
