Publishdate：2018-05-15 Views：41
Following the low-temperature SCR denitrification project of Tangshan Ruifeng Steel's sintering flue gas, recently, Beijing Fangxin Lihua Technology Co., Ltd. successfully signed the Tangshan Songting Steel Co., Ltd. sintering flue gas low-temperature SCR denitrification project.
The 300 ㎡ sintering machine with an annual output of 3.5 million tons of sintered ore will be added for low-temperature SCR denitrification this time. The flue gas treatment process flow is as follows: "Limestone gypsum desulfurization flue gas+GGH heat exchange+flue gas temperature rise+low-temperature SCR denitrification+GGH heat exchange+induced draft fan+chimney emission". The designed export index is: NOx concentration: ＜ 40 mg/Nm3 ³； Ammonia escape: ≤ 5ppm; The operating temperature of the catalyst is 180 ℃. It is reported that this is a low-temperature SCR denitrification project after wet desulfurization of domestic sintering machines; At the same time, the emission standard for NOx concentration, which is less than 40 mg/Nm3, also marks the official start of ultra-low nitrogen oxide emissions in the sintering industry.
As a company that has been engaged in low-temperature SCR denitrification research and development for a long time in China, Beijing Fangxin Lihua Technology Co., Ltd. regards technological innovation as the foundation of enterprise survival, continuously increases technological research and development, expands new areas of air pollution control business, and strives to create "China's low-temperature denitrification products". The low-temperature series catalysts developed by it have been successfully applied in nearly a hundred sets of projects in dozens of industries, including steel, coking, waste incineration, refractory materials, cement, glass, ceramics, papermaking, acid washing, etc.
