水幕降尘装置研制与实践应用
|
摘要
云岗矿复采81003工作面在初次降尘除尘后,粉尘浓度仍达不到规定的标准。针对此情况设计研制了一款水幕除尘装置,将其安装在距工作面5m处的回风巷道内。数据检测表明:经过二次降尘除尘后效果达到了92%以上,有效地保障了该回风巷道设备和人员的安全。该款水幕除尘装置安装简单,操作方便,适合大面积推广使用。
The dust concentration of 81003 working face after primary dust removal in Yungang Coal Mine is still not up to the prescribed standard. In view of this situation, a water curtain dust removal device was designed and developed, which was installed in the air return tunnel 5 m away from the working face. Data test shows that the effect of dust removal after secondary dedusting reaches more than 92%, effectively ensuring the safety of equipment and personnel in the air return tunnel. The water curtain dust removal device is simple to install, easy to operate and suitable for large-scale promotion.
