What is a SCR low-temperature catalytic absorption flue gas denitrification? Introduction to the advantages, characteristics, and principles of the SCR flue gas denitrification

SCR low-temperature catalytic absorption flue gas denitrificationdelective catalytic reduction technology is an efficient flue gas denitrification technology.，at work,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.。

1、Brief introduction of SCR low-temperature catalytic absorption flue gas denitrification

2、Introduction of SCR low-temperature catalytic absorption flue gas denitrification characteristics

SCR low-temperature catalytic absorption flue gas denitrification has the following characteristics

1. energy saving and environmental protection

This technology can effectively reduce NOx emission in flue gas, reduce environmental pollution, and at the same time, it has stable operation and low energy consumption, which meets the requirements of energy saving and environmental protection.

2. 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.

3. Small secondary pollution

The by-products produced in the SCR low-temperature catalytic absorption flue gas denitrification opening process are nitrogen and water vapor, and there is no secondary pollution problem.

4. Mature technology

After years of development and application, SCR low-temperature catalytic absorption flue gas denitrification technology is very mature and has a wide application prospect.

5. Small secondary pollution

The by-products produced in the SCR low-temperature catalytic absorption flue gas denitrification opening process are nitrogen and water vapor, and there is no secondary pollution problem.

3、Structural advantages of SCR low-temperature catalytic absorption flue gas denitrification

The SCR low-temperature catalytic absorption flue gas denitrification has the following structure

1. Reactor

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

2. 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.

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. control system

The whole SCR low-temperature catalytic absorption flue gas denitrification 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.

5、How much is the SCR low-temperature catalytic absorption flue gas denitrification?

The SCR low-temperature catalytic absorption flue gas denitrification price is introduced as follows:

1. product function

The more functions a product has, the higher its manufacturing cost, so that the product can be used by customers as much as possible, which can create more useful value for customers, so the price will be higher.

2. select a qualified person

Different manufacturers have different material selection standards. The better the quality of the selected materials, the more expensive the products will be. On the contrary, the prices will be low. However, to avoid customers being deceived, compare several products of the same specification and model before deciding to purchase.

3. cost of production

Product manufacturers are different, and the cost spent by each manufacturer in producing products is definitely different. The higher the cost of producing products, the higher the price of products set by manufacturers. On the contrary, the SCR low-temperature catalytic absorption flue gas denitrification price is low.

4. region

Different provinces and regions have different consumption levels, different market positioning and different prices.

5. mass discrepancy

If the quality of the product is guaranteed, its service life will be longer. At the same time, the more perfect the performance, the more economic value can be created for customers, and the price of such products will be higher. One-combustion energy saving has strictly controlled the quality and the sales price is also reasonable.

6、One-combustion energy saving's strength

The company has many years of SCR low-temperature catalytic absorption flue gas denitrification manufacturing experience, large scale and strong strength.。

One-combustion energy saving

SCR low-temperature catalytic absorption flue gas denitrificationis a SCR low-temperature catalytic absorption flue gas denitrification，at 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.。
