What is a SCR low-temperature catalyst denitrification? How much is the price of the SCR denitration?
SCR low-temperature catalyst denitrificationthat is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.,it has the functions of Improve working conditions, Improve energy efficiency, Promote sustainable development, environmental protection and Improve working conditions。The following is to introduce the SCR low-temperature catalyst denitrification:
1、Brief introduction of SCR low-temperature catalyst denitrification
SCR low-temperature catalyst 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.,is a kind of high quality and low price SCR low-temperature catalyst denitrification,has been favored by more and more customers.。

2、SCR low-temperature catalyst denitrification principle
SCR low-temperature catalyst denitrificationthe principle is simple.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.,the main features are Strong adaptability, Environmental protection and pollution-free, Less secondary pollution, Strong adaptability and Mature technology,It has a wide range of uses, and is often used inMeet the requirements of environmental protection,Flue gas denitrification,Improve product quality,Promote sustainable development,environmental protection and so on,it is widely used in cement plant, coal-fired power station, building materials, metallurgy, iron and steel plant and other industries,the full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.。

3、SCR low-temperature catalyst denitrification structure composition
The SCR low-temperature catalyst denitrification structure is introduced as follows:
- Reducing agent supply
- Catalytic reduction reaction
- Reducing agent storage and supply system
- Flue gas mixing and distribution
- control system
Reducing agents such as liquid pure ammonia or ammonia water (aqueous solution of ammonia) are evaporated and mixed with diluted air or flue gas.
Under the action of catalyst, the reductant and NOx in flue gas undergo selective catalytic reduction reaction to generate nitrogen and water vapor.
Used to store and supply reducing agent (such as ammonia or urea solution) to the reactor.
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.
The whole SCR low-temperature catalyst 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.

4、SCR low-temperature catalyst denitrification characteristics
The SCR low-temperature catalyst denitrification features are as follows:
- Strong adaptability
- High denitration efficiency
- selectivity
- Mature technology
- Stable operation and stability
SCR low-temperature catalyst denitrification technology can meet the needs of flue gas denitrification under different working conditions and has a wide range of applications.
The denitration efficiency of SCR low-temperature catalyst denitrification technology can reach more than 90%, and it is a widely used post-combustion denitration technology at present.
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.
After years of development and application, SCR low-temperature catalyst denitrification technology is very mature and has a wide application prospect.
The technology runs stably and reliably, and is suitable for various scenarios with large changes in flue gas flow, composition and concentration.

As you can see from the live video.,Shandong yiran energy-saving environment protection co., ltd 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.。
6、SCR low-temperature catalyst denitrification price consultation
The SCR low-temperature catalyst denitrification price is introduced as follows:
- specifications and models
- Product technology
- select a qualified person
- Quality advantages and disadvantages
- cost of production
The same equipment, even with different models and different configurations, has different investment costs, so the price will be different.
Different manufacturers have different advanced technologies, different production processes and different performances, and the price difference is naturally quite large.
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.
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.
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 catalyst denitrification price is low.
