瑞典阿特拉斯科普科公司研制的DCT干式尘捕器,由旋风除尘器或撞击板加滤尘袋组成。据资料介绍,其捕尘效率为99.9％,对于5微米以上的粉尘捕尘效果几乎达100％。除手持式凿岩机外,其他阶段式凿岩机的捕尘器都装在台车上,随车移动,使用方便,结构紧凑。由于采用滤尘袋捕尘,在含水的岩层中钻眼,含湿量每米钻孔达5公升以上时,不宜使用该捕尘器,以免粉尘粘糊滤袋而无法振落复原。在温度低于零下10.5℃使用
Developed by Atlas Copco Sweden DCT dry dust trap, the cyclone or impact board plus dust bag composition. According to the information, the dust catching efficiency is 99.9%, and the dust catching effect is almost 100% for the dust above 5 microns. In addition to hand-held rock drill, the other stage rock drill dust collectors are mounted on the trolley, move with the car, easy to use, compact structure. Due to the use of dust filter bag dust, drilling in the water-bearing rock formations, moisture content of more than 5 liters per meter drilling holes, it is not appropriate to use the filter to prevent dust sticky filter bag and can not shake off recovery. Use at temperatures below minus 10.5 ° C
