铁合金烟气治理及硅微粉的回收利用

Gas control and recovery and utilization of microspheric silica of ferro-silicon

铁合金行业属高能耗重污染行业 ,烟尘中主要成份二氧化硅经收尘处理后称为硅微粉 ,有广泛用途和良好的市场前景。论证了采用正压式袋式除尘技术回收硅微粉 ,估算其治理回收的投资及效益 ,具有很好的经济效益和环境效益 ;

Ferro-silicon industry is highly energy-consuming and causes serious environmental pollution. The main composition of the dust is silica, also called microspheric silica after being collected and treated. This magical material is widely used and has a bright market prospective. This paper demonstrates the advantage of dust bag filter with positive pressure over that with negative pressure. The calculation of investment in and benefit from control and recovery of the dust shows that utilization of microspheric silica will produce very good economic and environmental results. The impact of a ferro-silicon factory on the environmental air is predicted by using a prediction model for air pollution.
