Oxidation reduction denitrification equipmentdelective catalytic reduction technology is an efficient flue gas denitrification technology.，is a Oxidation reduction denitrification equipment，It is mostly used in environmental protection, Improve product quality, Meet the requirements of environmental protection, Flue gas denitrification, environmental protection, Promote sustainable development 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.，modern technology。The following is to introduce the Oxidation reduction denitrification equipment:

2、Oxidation reduction denitrification equipment advantage

The advantages of Oxidation reduction denitrification equipment are as follows:

1. Diversity and high efficiency of catalysts

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

2. Environmental friendliness

The by-products produced by Oxidation reduction denitrification equipment 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 Oxidation reduction denitrification equipment 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.

3. 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 Oxidation reduction denitrification equipment technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Oxidation reduction denitrification equipment technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.

4. Wide applicability

Oxidation reduction 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 Oxidation reduction 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.

5. 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 Oxidation reduction 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.

3、Oxidation reduction denitrification equipment characteristics

The Oxidation reduction denitrification equipment features are as follows:

1. Small secondary pollution

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

2. 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.

3. 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.

4. Strong adaptability

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

5. High denitration efficiency

The denitration efficiency of Oxidation reduction denitrification equipment technology can reach more than 90%, and it is a widely used post-combustion denitration technology at present.

4、Structural advantages of Oxidation reduction denitrification equipment

The Oxidation reduction denitrification equipment has the following structure

1. 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.

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. Temperature control and monitoring system

It is used to monitor and control the temperature of the reactor to ensure that the chemical reaction is carried out in the optimal temperature range.

4. 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.

5. Reducing agent storage and supply system

Used to store and supply reducing agent (such as ammonia or urea solution) to the reactor.

5、Working principle of Oxidation reduction denitrification equipment

Oxidation reduction denitrification equipmentat the start of the operation,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.，it has the functions of Improve working conditions, Promote sustainable development, Improve energy efficiency, environmental protection and Improve working conditions，it is an ideal choice for customers to buy Oxidation reduction denitrification equipment。
