摘　　要：马钢矿业桃冲矿为解决粉尘的达标排放问题,开展了筛分楼除尘系统改造。结果表明,新设置的2套除尘系统减少了管网布置,降低了管理和维护难度,达到了经济高效运行的效果;应用风量10.1万m^(3)/h和7万m^(3)/h除尘器后,现场岗位总粉尘浓度降至0.9 mg/m^(3),新型褶皱式滤筒使排气筒排放浓度降至4.6 mg/m^(3)和5.5 mg/m^(3),达到了除尘系统排气筒大气污染物排放浓度标准要求;新型褶皱式滤筒适用于高黏性粉尘,较好地解决了困扰白云石矿高黏性粉尘糊袋及岗位粉尘浓度超标等问题。In order to solve the problem of standard discharge of dust in Taochong Mine of Masteel Mining,the dust removal system of screening tower has been reformed.The results showed that the two dust removal systems which are set newly decrease the pipe network layout,reduce the difficulty of man agement and maintenance,thus achieve the effect of economic and efficient operation.When the dust col lectors with air quantity of 101000 m^(3)/h and 70000 m^(3)/h were applied,the total dust concentration of the site position reduced to 0.9 mg/m^(3),and the new fold filter cylinder can reduce the exhaust pipe emission concentration to 4.6 mg/m^(3)and 5.5 mg/m^(3),which meets the standard requirements of air pollutant emission concentration of the exhaust pipe of the dust removal system.The new fold filter cylinder is suitable for high viscosity dust,which better solves the problems of high viscosity dust paste bag and excessive dust concen tration in dolomite mine.
