What is a SCR catalyst denitrification? Introduction to the Working Principle of SCR denitration

2025-5-27

SCR catalyst denitrificationdelective catalytic reduction technology is an efficient flue gas denitrification technology.,it is widely used in cement plant, metallurgy, coal-fired power station, Gas power plant, building materials and other industries,the product looks beautiful.,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.,was developed and designed by One-combustion energy saving。The following is to introduce the SCR catalyst denitrification:

1、Brief introduction of SCR catalyst denitrification

2、Structural advantages of SCR catalyst denitrification

The SCR catalyst denitrification has the following structure

  1. Flue gas mixing and distribution
  2. 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.

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

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

  7. Reactor
  8. It is the core component of SCR catalyst denitrification technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.

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

3、SCR catalyst denitrification performance advantage

SCR catalyst denitrifications have the following advantages.

  1. Intelligent control and convenience of operation
  2. The SCR catalyst denitrification has gradually realized intelligent control. By integrating advanced control system and sensor technology, the SCR catalyst 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.

  3. Diversity and high efficiency of catalysts
  4. There are many kinds of catalysts used in the SCR catalyst denitrification 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 SCR catalyst denitrification technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.

  5. economic viability
  6. 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 SCR catalyst denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR catalyst denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.

  7. Wide applicability
  8. SCR catalyst denitrification 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 SCR catalyst denitrification 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.

  9. Mature and stable technology
  10. SCR catalyst denitrification technology has been developed and applied for many years, and the technology is mature and stable. The SCR catalyst denitrification has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the SCR catalyst denitrification technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.

5、How much is the SCR catalyst denitrification?

The SCR catalyst denitrification price is introduced as follows:

  1. company strength
  2. The nature of the manufacturer can also greatly affect the price of the SCR catalyst denitrification. General manufacturers are divided into direct sellers, agents and middlemen. If they are direct selling manufacturers, there are not too many intermediate links, and their sales prices are low.

  3. technology content
  4. Different manufacturers have different advanced technologies, different production processes and different performances, and the price difference is naturally quite large.

  5. select a qualified person
  6. The quality of material selection is one of the main factors that directly affect the SCR catalyst denitrification. If the quality of material selection is better, the price may be more expensive. Therefore, customers must first understand the quality of material selection before purchasing products, and then compare whether the quality and price match.

  7. Quality advantages and disadvantages
  8. Quality generally refers to the quality of the product. The better the quality, the higher the quality of the product. Because the quality is directly proportional to the cost of the product, the price of the SCR catalyst denitrification will vary greatly. One-combustion energy saving attaches great importance to the quality of products, and the formulation of prices is also reasonable.

  9. product configuration
  10. There is a direct connection between configuration and specifications. Generally speaking, with different specifications, its configuration scheme will be different, and the selection of products' materials and parts will be different, so the sales price of products will be different. It is not difficult to see that the configuration and price of SCR catalyst denitrification are closely related. One-combustion energy saving has comprehensively measured the configuration and sales price of products when designing SCR catalyst denitrification, which not only ensures that the functions of products can meet the actual needs of customers, but also can be in terms of price.
