太平煤矿复采采煤工作面产尘大,在采取初次降尘除尘后,仍然达不到煤矿安全规定的矿井空气质量标准,针对该问题,研制了一种水幕除尘装置,安置在距工作面5 m处的回风巷道内,利用除尘液在水幕除尘装置中的纱网小孔上形成水膜的原理,吸附进入回风巷道内的工作面污风中的粉尘,达到对工作面二次降尘除尘的效果。结果表明,在回风巷道内安置水幕除尘装置对工作面再次降尘除尘,使得两次降尘除尘效果达到90%以上,很好地保证了回风巷道内设备和人员的安全,也极大地提高了矿井内空气质量。
In the coal mining face of Taiping Coal Mine, large dust is produced, and after the first dust removal and dust removal, the coal mine air quality standards still fail to meet the coal mine safety requirements. In response to this problem, a water curtain dust removal device was developed, 5m Department of the return airway, the use of dust in the water curtain device in the screen of small holes in the film to form a film of water on the principle of adsorption into the return airway dust in the face of the work surface to reach the face of two The effect of dust reduction dust. The results show that installing the water curtain dust removal device in the air return roadway reduces the dust again on the working face so that the dust removal efficiency of the two dustfalls reaches more than 90%, which well ensures the safety of equipment and personnel in the air return roadway and also greatly improves Mine air quality.
