我国钢铁企业每年产生超过1亿t的高炉矿渣,且作为废渣未得到开发利用,多露天堆放,占用大量土地,污染生态环境。21世纪初,高炉矿渣粉磨设备技术和矿渣微粉应用经济技术得到钢铁行业的关注,多条矿渣粉磨生产线投产,促进了冶炼废渣的无害化、资源化处理,保护了生态环境。但矿渣微粉生产工艺产生大量的粉尘,且粒度细、浓度高、含水量高,使微粉线上的袋式除尘器常产生阻力高、易糊袋、卸灰困难等问题,所以根据微粉生产线实际情况选择及设计合适的袋式除尘器尤为重要。1矿渣微粉线收尘器的使用状况矿渣微粉要达到的一定的比表面积,其潜在活性
Each year, China’s iron and steel enterprises produce more than 100 million tons of blast furnace slag, and have not been exploited and utilized as wastes, so they are exposed in the open air and occupy a large amount of land and pollute the ecological environment. At the beginning of 21st century, blast furnace slag grinding equipment technology and application of economic technology of slag powder got the attention of the steel industry. A number of slag grinding production lines were put into operation, which promoted the innocuous and resourceful treatment of smelting waste and protected the ecological environment. But the slag powder production process produces a large number of dust, and the fine size, high concentration, high water content, so that the bag filter on the fine line often have high resistance, easy bagging, unloading ash and other issues, according to the actual production line Case selection and design of the bag filter is particularly important. 1 slag powder line dust collector use of slag powder to achieve a certain specific surface area, its potential activity
