| 摘 要： | 针对煤矿瓦斯抽采PVC管道静电引起的瓦斯爆炸事故,分析了PVC管道中静电产生和静电放电的原因,提出了预防PVC管道中静电灾害的技术.由于瓦斯在PVC抽放管路中流动时产生静电并在管道内壁产生静电积聚,所以在PVC管路和铁质流量计连接处,因两者导电能力不同,致使PVC管路产生静电,恰巧这时的瓦斯浓度达到爆炸范围,静电放电火...

| Abstract: | A case of gas explosion caused by electrostatic discharge in PVC pipeline for coal mine gas extraction was presented.The reasons of electrostatic generation in PVC pipeline and its discharge were analyzed.Prevention measures of electrostatic disaster in PVC pipelines were proposed.Cause of the accident is: when gas flows in PVC pipeline static electricity generates and accumulates on the inner wall of pipeline.At the connection of PVC pipeline with flow meter made of iron,discharge of static electricity occ... |
