为消除瓦斯抽采钻孔施工中湿式排渣消尘污水大量排放、干式排渣粉尘易大面积扩散的环境污染隐患,研制出轻便、小巧、成本低的导引捕尘一体装置;其主要依据轴承传动、喷雾定向导引的原理,在煤粉湿润后在自重作用下经出渣导引器、胶管落入洗气沉降池中;装置的整体设计避免了拆分、组装的复杂工序,钻杆可整体进入与退出降尘喷雾腔,未影响瓦斯钻孔施工进度。在现场进行了捕尘装置的应用验证,消尘效果达75.8%。 In order to eliminate the large amount of discharge of wet slag discharge dust and sewage in the process of gas drainage and drilling and the potential environmental pollution caused by the spread of dry slag dust in large area, a portable, compact and low cost guided dust catching integrated device was developed; its main According to the principle of bearing transmission and spray orientation guidance, after the pulverized coal is moistened, it flows into the scrubbing sedimentation tank through the slag guider and the rubber hose under the dead weight; the overall design of the device avoids the complicated processes of splitting and assembling, Drill pipe can enter and exit the dust spray chamber as a whole without affecting the progress of gas drilling. At the scene of the application of dust capture device validation, dust removal effect of 75.8%.
