Introduction to Catalyst based denitrification and SCR denitration structure principle

Catalyst based denitrificationis an efficient, stable and environment-friendly flue gas denitrification technology.，There are many kinds of catalysts used in the technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at a lower 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 Catalyst based denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Catalyst based 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.、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. Compared with the traditional wet flue gas denitrification technology, the Catalyst based 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.、The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Catalyst based denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Catalyst based denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Catalyst based 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 is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.，the product looks beautiful.，is a kind of high quality and low price Catalyst based denitrification，it has the functions of Promote sustainable development, environmental protection, Improve energy efficiency, Promote sustainable development and Improve working conditions。The following is to introduce the Catalyst based denitrification:

4、Structural advantages of Catalyst based denitrification

The Catalyst based denitrification has the following structure

1. Catalytic reduction reaction

Under the action of catalyst, the reductant and NOx in flue gas undergo selective catalytic reduction reaction to generate nitrogen and water vapor.

2. control system

The whole Catalyst based denitrification is automatically controlled to ensure the stable operation of the system and achieve the expected denitration effect.

3. Flue gas mixing and distribution system

Ensure that the flue gas and reducing agent are fully mixed in the reactor to improve the denitrification efficiency.

4. Reducing agent supply

Reducing agents such as liquid pure ammonia or ammonia water (aqueous solution of ammonia) are evaporated and mixed with diluted air or flue gas.

5. Reactor

It is the core component of Catalyst based denitrification technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.

Catalyst based denitrificationmultifunctional, with functions such as Improve working conditions, Promote sustainable development, environmental protection, Improve energy efficiency and Improve working conditions，the main structure includes Temperature control and monitoring system, Catalyst reactor, Flue gas mixing and distribution system, control system, Catalyst supply system and so on，at 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.。
