摘要
硅微粉是冶炼硅铁和金属硅时被烟气带出炉外的无晶形细颗粒,其主要成分是SiO2,具有优越的火山灰性能。随着国家环保法的逐步落实和人们环保意识的提高以及硅微粉应用领域的日益扩大,硅系铁合金生产厂家相继新建或配套改造了烟气净化系统,即硅微粉生产系统。回收硅微粉,尽可能使废物资源化和无害化,减少工业生产对人类和环境的影响,既有经济效益,又有社会和环境效益。
Silicon tiny powder is tiny amorphism grain that is carried out by smoke when we smelt ferrosilicon and metal silicon. Its major composition is SiO2, and it has superior pozzuolana performance. New establishment and mating reformation of flue gas cleaning system, silicon tiny powder system is in accordance with the gradual implementation of national environmental protection regulations, the enhancement of people's environmental protection sense and the enlargement of applied area. Recovery of silicon tiny powder possibly makes discards recycle harmlessly and reduces impact of industrial production on human and environment. It not only has economic benefit, but also has social and environment benefit.
