| Abstract: |
| Based on the issue of dust pollution in yard which is caused by the impact air flow when unloading ore, a new technology that using dry fog to control dust pollution of concentrated dust points in the main orepass and fugitive dust points in the yard was proposed. The process of dry fog dust removal was analyzed on a micro level, and the technology had been applied to remove the dust from -570 m unloading yard in Hubei Sanxin Gold Copper Co., Ltd. The results showed that: the total dust removal efficiency was as high as 95.25%, the respirable dust removal efficiency was up to 96%. The issue of dust pollution in the main orepass had been fundamentally solved, the working environment had been greatly improved. The technology consumes less water, gas and electricity; and has low operation cost as well as high dust removal efficiency. |
