由鞍钢大孤山铁矿和长沙矿山研究院组成的三结合的牙轮钻机除尘试验组,为了适应气候寒冷的条件,经过三年多来的试验,在吸取了兄弟矿山先进经验的基础上,研制成由捕尘罩一百叶栅除尘器-旋风除尘器和脉冲布袋除尘器组成的四级干式除尘装置(附图)。它已运转三个多月,经历了雨天作业,穿孔3000多米,整个系统使用正常,效果良好。含尘浓度排风口为11.1毫克/米~3(附表),捕尘罩周围为2.1毫克/米~3,司机室(无净化装置)为2.3毫克/米~3。它不降低穿孔速度和钻头寿命,而废孔率比使用风水混合湿式除尘器时降低10%以上。捕尘罩是长方形的,长2600毫米,宽1800
From the Dagushan Iron Mine and Anshan Iron and Steel Research Institute of Changsha Iron and Steel Mining Research Institute composed of three combined roller cone dust test group, in order to adapt to the conditions of cold weather, after more than three years of testing, drawing on the advanced experience of brother mine, Developed by dust cover a hundred cascade precipitator - cyclone and pulse bag filter composed of four dry dust removal device (with photos). It has been operating for more than three months, has experienced rainy day work, perforated more than 3000 meters, the entire system is in good condition and the effect is good. Dust concentration of the exhaust port is 11.1 mg / m ~ 3 (schedule), around the dust cover 2.1 mg / m ~ 3, cab (no purification device) 2.3 mg / m ~ It does not reduce the perforation speed and bit life, while the waste hole ratio is reduced by more than 10% when using a feng shui hybrid wet scrubber. Dust cover is rectangular, 2600 mm long, 1800 wide
