Introduction to Steel industry flue gas denitrification system and SCR denitration working principle

Steel industry flue gas denitrification systemis an efficient, stable and environment-friendly flue gas denitrification technology.，the principle is simple.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.，The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Steel industry flue gas denitrification system technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Steel industry flue gas denitrification system technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Steel industry flue gas denitrification system technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.、The technology is suitable for many industries and processes, such as coal-fired power plants, iron and steel smelting, cement production and so on. These industries will produce a large number of NOx emissions in the production process, and the Steel industry flue gas denitrification system technology can provide effective denitrification solutions for them. In addition, the gate technology can be adjusted and optimized according to different flue gas components and emission requirements to meet different denitration requirements.、There are many kinds of catalysts used in the technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at a lower temperature. At the same time, the active components and carrier materials of the catalyst are constantly being developed and improved to improve its catalytic efficiency and service life. This enables the Steel industry flue gas denitrification system technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、Technology has been developed and applied for many years, and it is mature and stable. The Steel industry flue gas denitrification system has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Steel industry flue gas denitrification system technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.，in the course of work,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.，is a popular Steel industry flue gas denitrification system。The following is to introduce the Steel industry flue gas denitrification system:

2、Structural characteristics of Steel industry flue gas denitrification system

The Steel industry flue gas denitrification system has the following structure

1. Reducing agent storage and supply system

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

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. 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.

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. control system

The whole Steel industry 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.

5、Steel industry flue gas denitrification system quotation

The Steel industry flue gas denitrification system price is introduced as follows:

1. Manufacturer scale

Our factory is a direct selling manufacturer of Steel industry flue gas denitrification system, with independent production and processing facilities, few circulation links and low circulation cost.

2. market quotation

Market change is one of the factors that affect the price range greatly. Market change is unstable, but there are certain rules to follow. Market change is caused by other factors, such as economic instability, competition among manufacturers and too big difference between supply and demand. These factors are the core reasons that cause the market to fluctuate greatly, and then it will have a bad impact on prices.

3. mass discrepancy

Generally speaking, the higher the product quality, the higher the Steel industry flue gas denitrification system price. A reasonable balance is made between quality and price, so that the comprehensive quality of the product can meet the customer's use standards and meet the basic needs of customers in terms of price.

4. Overall configuration

Products of the same style, different configurations, the product price is definitely different, therefore, the Steel industry flue gas denitrification system price is affected by the configuration, and the price varies.

5. market supply and demand

The amount of customers' demand for Steel industry flue gas denitrification system in the market also has a great influence on the price. When there are many customers purchasing this product in the market and the supply quantity of manufacturers is small, the Steel industry flue gas denitrification system price will be very high. On the contrary, when fewer customers purchase this product, there will be a phenomenon of oversupply, and the price of Steel industry flue gas denitrification system will naturally be reduced.

One-combustion energy saving

Steel industry flue gas denitrification systemis a kind of high quality and low price Steel industry flue gas denitrification system，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 has the functions of environmental protection, Improve energy efficiency, Improve working conditions, Promote sustainable development and Improve working conditions。
