Introduction to Denitrification of roasting furnace, advantages, characteristics and principles of SCR denitration

Denitrification of roasting furnaceis an efficient, stable and environment-friendly flue gas denitrification technology.，widely used in cement plant, Gas power plant, iron and steel plant, metallurgy, building materials and other fields。

1、Brief introduction of Denitrification of roasting furnace

Denitrification of roasting furnacethat is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.。

2、Advantages of Denitrification of roasting furnace principle

Denitrification of roasting furnaceat 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.，it is mainly composed of Flue gas mixing and distribution system, Catalyst supply system, Temperature control and monitoring system, Catalyst reactor and control system，This productThe structure is novel, special, advanced, reasonable and scientific.，has been favored by more and more customers.。

3、Introduction of Denitrification of roasting furnace characteristics

Denitrification of roasting furnace 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. Mature technology

After years of development and application, Denitrification of roasting furnace technology is very mature and has a wide application prospect.

3. Small secondary pollution

The by-products produced in the Denitrification of roasting furnace opening process are nitrogen and water vapor, and there is no secondary pollution problem.

4. high efficiency

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

5. Environmental protection

The final products of Denitrification of roasting furnace technology are harmless nitrogen and water vapor, which will not cause secondary pollution to the environment.

4、Denitrification of roasting furnace structure composition

The Denitrification of roasting furnace 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. Reactor

It is the core component of Denitrification of roasting furnace technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.

3. Flue gas mixing and distribution system

Ensure that the flue gas and reducing agent are fully mixed in the reactor to improve the denitrification efficiency.

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 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.
