矿用气动湿式孔口除尘器的研发及应用

摘要

According to the dust pollution problems of the dry drilling in the underground mine,a new mine dust collector of the borehole collar with an integration of intrinsic safe,light weight and small type was studied.Based on the experiment analysis and study on the main factors affected to the dust collection effect,a systematic study was conducted on the key power element-pneumatic ejector.A lab experiment and industrial experiment was conducted on the main performances of the dust collector.The experiment results showed that the total dust collection efficiency of the dust collector could reach at 99.1% and 98.6% individually.The dust collection efficiency of the respirable dust could reach at 94.1% and 93.2% individually.The mine safety production could effectively protected.%针对煤矿井下干式钻孔粉尘污染问题,研究了集本质安全、轻便、小型于一体的新型矿用气动湿式孔口除尘器。在对影响除尘效果的主要因素进行试验分析研究的基础上,对关键动力元件,即空气引射器进行了系统深入的研究,并对除尘器的主要性能进行实验室和工业性试验,试验结果表明：该除尘器总粉尘除尘效率分别达99.1%和98.6%,呼吸性粉尘除尘效率分别达94.1%和93.2%,有效保障了矿井安全生产。
