What is a SCR low-temperature denitrification? Introduction to the advantages and characteristics of the SCR denitration

SCR low-temperature denitrificationdelective catalytic reduction technology is an efficient flue gas denitrification technology.，Mainly used forenvironmental protection,Improve product quality,Improve product quality,environmental protection andFlue gas denitrification，it has the functions of Improve working conditions, Promote sustainable development, Improve energy efficiency, environmental protection and Improve working conditions，is designed by One-combustion energy saving with advanced technology。The following is to introduce the SCR low-temperature denitrification:

1、Brief introduction of SCR low-temperature denitrification

SCR low-temperature denitrificationit refers to the process of removing nitrogen oxides from flue gas to reduce environmental pollution. NOx is a pollutant harmful to the atmospheric environment, which has strong irritation and toxicity, and will lead to environmental problems such as acid rain and photochemical smog, and also endanger human health. The main principle of flue gas denitrification technology is to reduce NOx to nitrogen and water by adding appropriate reducing agent or catalyst in the combustion process or flue gas treatment system, so as to reduce NOx emission.，it is widely used in iron and steel plant, building materials, metallurgy, coal-fired power station and cement plant。

4、SCR low-temperature denitrification structure

The SCR low-temperature denitrification structure is introduced as follows:

1. Reactor

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

2. 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.

3. Reducing agent storage and supply system

Used to store and supply reducing agent (such as ammonia or urea solution) to the reactor.

4. control system

The whole SCR low-temperature denitrification is automatically controlled to ensure the stable operation of the system and achieve the expected denitration effect.

5. 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、Introduction of SCR low-temperature denitrification characteristics

SCR low-temperature denitrification has the following characteristics

1. High denitration efficiency

The denitration efficiency of SCR low-temperature denitrification technology can reach more than 90%, and it is a widely used post-combustion denitration technology at present.

2. 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.

3. high efficiency

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

4. Environmental protection

The final products of SCR low-temperature denitrification technology are harmless nitrogen and water vapor, which will not cause secondary pollution to the environment.

5. Stable operation and stability

The technology runs stably and reliably, and is suitable for various scenarios with large changes in flue gas flow, composition and concentration.

6、SCR low-temperature denitrification quotation

The SCR low-temperature denitrification price is introduced as follows:

1. service

Service factors always affect the sales price of products, and high-quality service will make customers have greater satisfaction and recognition. The service factors mainly include pre-sales service, in-sales service and after-sales service. For each stage of service, our company takes the price factor into account and makes a reasonable judgment between service and price, so that the SCR low-temperature denitrification price and service can meet the actual needs of customers.

2. deploy

If the comprehensive configuration of the product is higher, the selling price of the product will be higher, otherwise the price will be lower, so there is a close relationship between the configuration level and the price.

3. Manufacturer's sales model

One-combustion energy saving has long used the sales method of small profits but quick turnover to sell products, and the product price, market price and ex-factory price are the same. The purpose of this is to improve the sales volume of products and the visibility of enterprises.

4. product quality

Usually, the price of good quality products will be higher, because the product has higher technical content and more costs in raw materials and labor, but the performance of such products is higher and the profits will be higher. On the contrary, the price of ordinary quality products will be relatively lower, but the benefits will be correspondingly poor.

5. raw material

The raw materials used by manufacturers of different products will definitely be different. Some manufacturers use good raw materials for processing, and the cost of producing and manufacturing products is definitely high. If the quality of products produced by manufacturers is not guaranteed and the materials used are not very good, then the production cost of products will be low, and the price will be very low.
