炼钢电弧炉在冶炼过程巾产生大量烟尘,通常熔炼1吨钢,产生的灰尘有2～20公斤,吹氧时烟气中的含尘浓度可达10～22克/米~3。电炉烟尘成份较复杂,主要有氧化铁、二氧化硅、氧化钙、一氧化碳、硫、碳、氮等。如不采取排烟净化措施,不但影响生产、危害工人健康、也污染环境。经过无产阶级文化大革命,国内许多工厂,在党组织领导下,大搞群众运动,在电炉排烟净化方面,做了不少工作,使该项技术有了进一步的发展。现将我们了解的情况简介如下:
Steelmaking arc furnace smelting process towel produces a lot of dust, usually 1 ton of steel melting, the resulting dust 2 to 20 kg, blowing oxygen in the flue gas concentration of dust up to 10 ~ 22 g / m ~ Electric furnace soot composition is more complex, mainly iron oxide, silica, calcium oxide, carbon monoxide, sulfur, carbon, nitrogen and so on. If we do not take smoke purification measures, not only affect the production, endanger the health of workers, but also pollute the environment. After the Great Proletarian Cultural Revolution, many factories in China, under the leadership of the party organizations, engaged in the mass movement and done a lot of work in the purification of electric furnace smoke and exhaust gas to further develop the technology. Now we know about the situation are as follows:
