1、Brief introduction of SCR catalyst flue gas denitrification equipment

SCR catalyst flue gas denitrification equipmentit refers to the process of removing nitrogen oxides from flue gas to reduce environmental pollution. NOx is a pollutant harmful to the atmospheric environment, which has strong irritation and toxicity, and will lead to environmental problems such as acid rain and photochemical smog, and also endanger human health. The main principle of flue gas denitrification technology is to reduce NOx to nitrogen and water by adding appropriate reducing agent or catalyst in the combustion process or flue gas treatment system, so as to reduce NOx emission.，is a SCR catalyst flue gas denitrification equipment newly developed by One-combustion energy saving。

2、SCR catalyst flue gas denitrification equipment field real shot

The following is the live video of SCR catalyst flue gas denitrification equipment designed and produced by One-combustion energy saving for users, from which we can see the 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 SCR catalyst 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 is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.、The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of SCR catalyst flue gas denitrification equipment technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR catalyst flue gas denitrification equipment 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 SCR catalyst flue gas denitrification equipment technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、Technology has been developed and applied for many years, and it is mature and stable. The SCR catalyst flue gas denitrification equipment has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the SCR catalyst flue gas denitrification equipment technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.、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 SCR catalyst flue gas 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. of One-combustion energy savingproduction-manufacturing的SCR catalyst flue gas denitrification equipment.。

6、Structural advantages of SCR catalyst flue gas denitrification equipment

The SCR catalyst flue gas denitrification equipment has the following structure

1. 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.

2. 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.

3. Temperature control and monitoring

The temperature in the catalyst reactor is maintained within the optimal reaction temperature range through the temperature control and monitoring system.

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. Reactor

It is the core component of SCR catalyst flue gas denitrification equipment technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.

SCR catalyst flue gas denitrification equipmentgenerally, it is composed of control system, Flue gas mixing and distribution system, Temperature control and monitoring system, Catalyst supply system, Catalyst reactor and other major components，This SCR catalyst flue gas denitrification equipmentThe overall structural design is relatively simple and compact.，in the course of 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.。
