What is a SCR catalytic reduction flue gas denitrification equipment? Introduction to the advantages and characteristics of the SCR denitration system

SCR catalytic reduction flue gas denitrification equipmentthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，the main features are energy saving and environmental protection, Strong adaptability, Mature and stable technology, Less secondary pollution and Environment friendly。

1、Brief introduction of SCR catalytic reduction flue gas denitrification equipment

SCR catalytic reduction flue gas denitrification equipmentit 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 has the functions of Improve product quality, Meet the requirements of environmental protection, Meet the requirements of environmental protection, Flue gas denitrification and Promote sustainable development，in the course of 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.，is a kind of high quality and low price SCR catalytic reduction flue gas denitrification equipment，is based on One-combustion energy saving is an advanced SCR catalytic reduction flue gas denitrification equipment developed by our company in combination with the actual situation of the industry。

2、Working principle of SCR catalytic reduction flue gas denitrification equipment

SCR catalytic reduction flue gas denitrification equipmentthe 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 by-products produced by the technology are mainly nitrogen and water vapor, which are harmless to the environment and will not cause secondary pollution. Compared with the traditional wet flue gas denitrification technology, the SCR catalytic reduction flue gas denitrification equipment technology does not need to use a lot of water resources and will not produce pollutants such as wastewater, which is more in line with the requirements of environmental protection and sustainable development.、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 SCR catalytic reduction flue gas denitrification equipment 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.、The by-products produced by the technology are mainly nitrogen and water vapor, which are harmless to the environment and will not cause secondary pollution. Compared with the traditional wet flue gas denitrification technology, the SCR catalytic reduction flue gas denitrification equipment technology does not need to use a lot of water resources and will not produce pollutants such as wastewater, which is more in line with the requirements of environmental protection and sustainable development.、The initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of SCR catalytic reduction flue gas denitrification equipment technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR catalytic reduction flue gas denitrification equipment technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、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 SCR catalytic reduction flue gas denitrification equipment technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.，low in price。
