矿山生产过程中产生的呼吸性粉尘,是造成矿工矽肺病的根本原因。冶金部武汉安全环保研究院新近研制成功的矿用湿式金属纤维层除尘器,为改善作业环境、保护工人身体健康、有效地控制粉尘提供了一种高效的装置和方法。该除尘器是由金属纤维栅板、直流旋风分离器、喷嘴及供水系统四部分组成;利用喷出的雾,使粉尘起凝,通过金属纤维栅嵌板,由分离器进行风水分离而起到综合捕尘的作用。该样机经过在白银有色金属露天矿和大冶铁矿尖林山井下矿的现场试用,露天矿潜孔钻干式作业除尘效率达98.1％,井下独头巷道双轨掘进工
Respiratory dust generated in the mine production process is the root cause of miners silicosis. Recently, Wuhan Institute of Safety and Environmental Protection, Ministry of Metallurgy, has successfully developed a mining wet-type metal fiber layer dust collector, which provides an efficient device and method for improving working environment, protecting workers’ health and effectively controlling dust. The dust collector is composed of a metal fiber grid plate, a DC cyclone, a nozzle and a water supply system. The dust is coagulated by the sprayed mist, separated by a separator through a metal fiber grating panel, Integrated dust catching effect. The prototype after a trial of silver non-ferrous metal surface mine and Daye Mine Sham Lin iron mine site, open-pit mining drilling DTH Dust removal efficiency of 98.1%, underground single-track tunneling
