潜孔钻机是目前我国露天矿应用较普遍的一种穿孔设备。由于作业时产生大量粉尘,严重污染采场大气。为此,我矿潜孔钻机除尘试验小组,试验摸索了一种比较理想的捕尘系统—蜗旋布袋除尘系统,在石灰石、白云石矿潜孔钻机作业的除尘方面,收到了良好效果,可使司机室的粉尘浓度降至0.2毫克/米~3,孔口为0.4毫克/米~3,除尘系统排放口为8.9毫克/米~3,达到了国家规定的卫生标准。蜗旋脉冲布袋除尘系统(见图1)是由捕尘罩1、蛇形吸尘胶管2、蜗旋除尘器
DTH drilling rig is currently more commonly used in China’s open pit drilling equipment. Due to the operation produces a lot of dust, seriously pollute the stope atmosphere. To this end, mine DTH drilling rig dust test group, the trial explored an ideal dust catching system - Cochlear bag dust removal system, limestone, dolomite DTH drill dust operations, received good results, but So that the driver’s room dust concentration dropped to 0.2 mg / m ~ 3, the orifice is 0.4 mg / m ~ 3, dust discharge system for the 8.9 mg / m ~ 3, reached the state health standards. Cochlein pulse bag dust removal system (see Figure 1) is covered by dust cover 1, snake-shaped suction hose 2, the cyclone
