2、Introduction of Catalyst based denitrification system characteristics

Catalyst based denitrification system has the following characteristics

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. Environmental protection

The final products of Catalyst based denitrification system technology are harmless nitrogen and water vapor, which will not cause secondary pollution to the environment.

3. high efficiency

Gate technology can effectively remove NOx from flue gas, and the denitrification efficiency can usually reach more than 90%.

4. Stable operation and stability

The Catalyst based denitrification system technology runs stably and can meet the requirements of flue gas treatment under different working conditions.

5. energy saving and environmental protection

This technology can effectively reduce NOx emission in flue gas, reduce environmental pollution, and at the same time, it has stable operation and low energy consumption, which meets the requirements of energy saving and environmental protection.

Catalyst based denitrification system

As you can see from the live video.，Shandong yiran energy-saving environment protection co., ltd in the course of 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.。

4、Working principle of Catalyst based denitrification system

Catalyst based denitrification systemat 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.。

5、Structural advantages of Catalyst based denitrification system

The Catalyst based denitrification system 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. 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.

3. Reactor

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

4. Flue gas mixing and distribution

The mixed reducing agent and flue gas are fully mixed in the mixing tube and evenly distributed to the catalyst reactor through the distribution system.

5. control system

The whole Catalyst based denitrification system is automatically controlled, including the adjustment of reducing agent supply, flue gas flow and temperature, so as to ensure the stable operation of the system and achieve the expected denitrification effect.

Catalyst based denitrification system

Catalyst based denitrification systemthe main features are energy saving and environmental protection, Environment friendly, Stable operation, Stable operation and Economically feasible，the advantage is 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 system 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.、Technology has been developed and applied for many years, and it is mature and stable. The Catalyst based denitrification system has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Catalyst based denitrification system 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 Catalyst based denitrification system 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 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 system 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 system technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、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 system technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.。
