5、Industrial heating furnace flue gas denitrification use
Industrial heating furnace flue gas denitrificationIt is a product series that integrates Improve product quality, Improve product quality, Promote sustainable development, environmental protection and Meet the requirements of environmental protection,it is widely used inmetallurgy,coal-fired power station,Gas power plant,metallurgy,cement plant and other industries,it mainly includes control system, Flue gas mixing and distribution system, Catalyst supply system, Catalyst reactor and Temperature control and monitoring system,This productThe overall structural design is relatively simple and compact.,that is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.,the advantage is Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Industrial heating furnace flue gas 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.、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 Industrial heating furnace flue gas denitrification 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 Industrial heating furnace flue gas denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Industrial heating furnace flue gas denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.、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 Industrial heating furnace flue gas 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.、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 Industrial heating furnace flue gas denitrification technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.。
