3、SCR low-temperature catalytic absorption flue gas denitrification equipment performance advantage

SCR low-temperature catalytic absorption flue gas denitrification equipments have the following advantages.

1. Wide applicability

SCR low-temperature catalytic absorption flue gas denitrification equipment 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 catalytic absorption flue gas denitrification equipment 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.

2. Diversity and high efficiency of catalysts

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

3. Intelligent control and convenience of operation

The SCR low-temperature catalytic absorption flue gas denitrification equipment has gradually realized intelligent control. By integrating advanced control system and sensor technology, the SCR low-temperature catalytic absorption flue gas denitrification equipment 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. 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 catalytic absorption flue gas denitrification equipment 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.
