3、Working principle of Foundry denitration equipment

Foundry denitration equipmentAmmonia 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.。

4、Foundry denitration equipment characteristics

The Foundry denitration equipment features are as follows:

1. selectivity

Under the action of catalyst, the reducing agent mainly reacts with NOx selectively, but less with other components (such as oxygen) in flue gas, thus reducing unnecessary consumption.

2. Small secondary pollution

The by-products produced in the Foundry denitration equipment opening process are nitrogen and water vapor, and there is no secondary pollution problem.

3. Environmental protection

The final products of Foundry denitration equipment technology are harmless nitrogen and water vapor, which will not cause secondary pollution to the environment.

4. Strong adaptability

Foundry denitration equipment technology can meet the needs of flue gas denitrification under different working conditions and has a wide range of applications.

5. Stable operation and stability

The Foundry denitration equipment technology runs stably and can meet the requirements of flue gas treatment under different working conditions.

5、Working principle of Foundry denitration equipment

Foundry denitration equipmentthe principle is simple.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.，the advantage is The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Foundry denitration equipment technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Foundry denitration equipment technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、Technology has been developed and applied for many years, and it is mature and stable. The Foundry denitration equipment has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Foundry denitration equipment technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Foundry denitration 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.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Foundry denitration 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 is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.、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 Foundry denitration equipment technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.。
