2025-5-27

Catalytic reduction flue gas denitrification equipmentdelective catalytic reduction technology is an efficient flue gas denitrification technology.,it is widely used in Gas power plant, cement plant, metallurgy, iron and steel plant, coal-fired power station and other industries,the product looks atmospheric.,features include energy saving and environmental protection, Less secondary pollution, Environment friendly, Stable operation and Mature and stable technology,at the start of the operation,Under the action of catalyst, reducing agents (such as ammonia, urea, etc.) react with nitrogen oxides in flue gas to convert them into harmless nitrogen and water vapor.。The following is to introduce the Catalytic reduction flue gas denitrification equipment:

1、Brief introduction of Catalytic reduction flue gas denitrification equipment

Catalytic reduction flue gas denitrification equipmentthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.,multifunctional, with functions such as Improve energy efficiency, environmental protection, Improve working conditions, environmental protection and Promote sustainable development。

As you can see from the live video.,One-combustion energy saving at runtime,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.。

4、Catalytic reduction flue gas denitrification equipment structure

The Catalytic reduction flue gas denitrification equipment structure is introduced as follows:

  1. Reducing agent supply
  2. 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. control system
  4. The whole Catalytic reduction flue gas denitrification equipment is automatically controlled to ensure the stable operation of the system and achieve the expected denitration effect.

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

  7. Flue gas mixing and distribution
  8. 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.

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

5、Catalytic reduction flue gas denitrification equipment principle

Catalytic reduction flue gas denitrification equipmentthe principle is simple.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.,super quality and competitive price。
