本钢第一炼钢厂矽铁、矽钙加工粉碎设备陈旧,工艺落后。在粉碎、筛分、运输过程中,粉料大量流失,室内粉尘弥漫,严重污染了环境,危害了工人的身体健康。 经过工艺改革,实行了密闭通风,采用机械回转反吹扁袋除尘器,净化含尘气体,经过半年的运转,至今性能可靠,效果良好。经有关部门测定,室内外粉尘浓度均达到国家规定的卫生标准(见表1)。
Benxi Iron and Steel Company’s first steel plant, silicon calcium processing equipment crushed obsolete, backward technology. In crushing, screening, transport process, a large loss of powder, indoor dust filled, seriously polluted the environment, endangering the health of workers. After the process of reform, the implementation of airtight ventilation, the use of mechanical rotary backflush flat bag dust collector, dust gas purification, after six months of operation, performance so reliable, good effect. The determination by the relevant departments, indoor and outdoor dust concentrations have reached the national health standards (see Table 1).
