What is a Steel plant denitrification? Introduction to the principle of SCR denitration system structure

Steel plant denitrificationdelective catalytic reduction technology is an efficient flue gas denitrification technology.，has been favored by more and more customers.。

1、Brief introduction of Steel plant denitrification

Steel plant 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.，the product looks atmospheric.，multifunctional, with functions such as Improve working conditions, Promote sustainable development, environmental protection, Improve energy efficiency and Improve working conditions。

Steel plant denitrificationmultifunctional, with functions such as Promote sustainable development, environmental protection, Improve energy efficiency, Improve working conditions and Promote sustainable development，the main structure includes Catalyst supply system, Temperature control and monitoring system, Catalyst reactor, Flue gas mixing and distribution system, control system and so on，at runtime,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.。

4、Introduction of advantages of Steel plant denitrification

Steel plant denitrifications have the following advantages.

1. Diversity and high efficiency of catalysts

There are many kinds of catalysts used in the Steel plant denitrification technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at low 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 plant denitrification technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.

2. Intelligent control and convenience of operation

The Steel plant denitrification has gradually realized intelligent control. By integrating advanced control system and sensor technology, the Steel plant denitrification can monitor the composition and emission concentration of flue gas in real time, and automatically adjust the injection amount of reductant and the active state of catalyst to ensure the stability and reliability of denitrification efficiency.

3. Wide applicability

Steel plant denitrification 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 plant denitrification 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.

5、Steel plant denitrification application

Steel plant denitrificationWidely used in environmental protection, Promote sustainable development, Improve product quality, Meet the requirements of environmental protection and environmental protection，The structural design is simple, novel and special.，it is usually composed of Flue gas mixing and distribution system, Temperature control and monitoring system, control system, Catalyst supply system and Catalyst reactor，it is widely used in metallurgy, Gas power plant, iron and steel plant, cement plant, coal-fired power station and other industries，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.，it is an ideal choice for customers to buy Steel plant denitrification。
