Denitrification equipment in the steel industry

As you can see from the live video.，One-combustion energy saving 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.。

3、Denitrification equipment in the steel industry principle

Denitrification equipment in the steel industryat the start of the operation,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 structural design is more advanced and reasonable.，it is usually composed of control system, Flue gas mixing and distribution system, Temperature control and monitoring system, Catalyst supply system and Catalyst reactor，the advantage is 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 Denitrification equipment in the steel industry 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 Denitrification equipment in the steel industry 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 Denitrification equipment in the steel industry technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Denitrification equipment in the steel industry 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 Denitrification equipment in the steel industry 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.、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 Denitrification equipment in the steel industry technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.，the product looks beautiful.，is based on One-combustion energy saving is a Denitrification equipment in the steel industry newly developed by One-combustion energy saving。
