2、Structural advantages of SCR flue gas denitrification system

The SCR flue gas denitrification system has the following structure

1. 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.

2. Reactor

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

3. control system

The whole SCR flue gas denitrification system is automatically controlled, including the adjustment of reducing agent supply, flue gas flow and temperature, so as to ensure the stable operation of the system and achieve the expected denitrification effect.

4. 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.

5. Reactor

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

3、Advantages of SCR flue gas denitrification system principle

SCR flue gas denitrification systemCatalysts 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 is widely used in building materials, metallurgy, cement plant, iron and steel plant, coal-fired power station and other industries，the product looks atmospheric.，the full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，is a popular SCR flue gas denitrification system。

6、How much is the SCR flue gas denitrification system?

The SCR flue gas denitrification system price is introduced as follows:

1. brand

Different brands of products in the same series have more or less differences in product prices, and different brands of SCR flue gas denitrification system have more or less differences in price.

2. company strength

Although there are many manufacturers of products in Jinan, there are certain differences in the scale and strength of each manufacturer. Some manufacturers are large in scale and strength, some are small in scale, and some manufacturers do not have their own production workshops and belong to middlemen. Relatively speaking, the prices of products formulated by middlemen are higher.

3. Product technology

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

4. Low cost of raw materials

The production cost determines the price. The production cost here mainly includes technology, materials, technology, manpower and other related factors, among which the technology content is high, and the cost is relatively high, but the performance will be better; The better the quality of raw materials, the greater the cost and the longer the overall life of the product; If the manufacturer has a rational manufacturing process and strict production management system, and can make full use of human and material resources, then it can reduce the waste of expenses and production costs to a great extent, and the SCR flue gas denitrification system just meets this condition, so as to ensure the high-tech content and high quality of products, it can also enjoy low prices.

5. Self quality

The quality of the product determines the production process and results. Good quality means that the raw materials of the product are better and the price will definitely be higher.

SCR flue gas denitrification system

SCR flue gas denitrification systemat the start of the operation,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.，at runtime,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.，it is widely used incement plant,coal-fired power station,building materials,metallurgy,Gas power plant and other industries。
