2、Working principle of SCR low-temperature flue gas denitrification

SCR low-temperature flue gas denitrificationat 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.，Widely used in Promote sustainable development, Flue gas denitrification, Improve product quality, Promote sustainable development and Flue gas denitrification。

5、Functional advantages of SCR low-temperature flue gas denitrification

SCR low-temperature flue gas denitrifications have the following advantages.

1. Diversity and high efficiency of catalysts

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

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 SCR low-temperature flue gas 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. Wide applicability

SCR low-temperature flue gas 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 SCR low-temperature flue gas 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.

4. economic viability

The initial investment of this technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of SCR low-temperature flue gas denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR low-temperature flue gas denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.

5. Environmental friendliness

The by-products produced by SCR low-temperature flue gas 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 SCR low-temperature flue gas 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.

SCR low-temperature flue gas denitrification

SCR low-temperature flue gas denitrificationCatalysts 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.，features include Less secondary pollution, Strong adaptability, Efficient denitration, Economically feasible and Mature and stable technology。
