What is a SCR denitration equipment? How much is the price of the SCR flue gas denitrification?

SCR denitration equipmentis an efficient, stable and environment-friendly flue gas denitrification technology.，at runtime,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 following is to introduce the SCR denitration equipment:

4、SCR denitration equipment principle

SCR denitration equipmentin the course of work,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 overall structural design is relatively simple，it has the structure of Catalyst supply system, control system, Temperature control and monitoring system, Flue gas mixing and distribution system and Catalyst reactor。

SCR denitration equipment

SCR denitration equipmentThe initial investment of technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of SCR denitration equipment technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR denitration equipment technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the SCR denitration equipment 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.、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 denitration equipment technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、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 denitration 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.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the SCR denitration equipment 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 main structure includes control system, Temperature control and monitoring system, Catalyst reactor, Flue gas mixing and distribution system, Catalyst supply system and so on，usually used in coal-fired power station, building materials, metallurgy, iron and steel plant, cement plant and other fields。
