Abstract:

针对矿井瓦斯抽采在PVC管壁电荷积聚产生强静电场而导致静电放电的危害,通过搭建塑性管瓦斯流动静电场测试装置,模拟测试瓦斯流动过程中塑性管道的静电场,同时数值计算静电放电有效点火能量。研究结果表明,改变瓦斯流速、管径和瓦斯浓度,PVC管静电场总体趋势是开始时电场随时间逐渐增大,而后趋于稳定,流动瓦斯与PVC管壁面摩擦产生电荷积聚而导致的静电场可达20kV/m以上。以甲烷的最小点燃能量0.28mJ为标准,大多时刻PVC管静电放电有效点火能量小于0.28mJ,处于安全状态,但某些时刻有效点火能量大于0.28mJ,使得瓦斯处于爆炸的最小点火能量范围。从试验分析瓦斯抽采PVC管静电场及有效点火能量,可为矿井瓦斯抽采防静电措施提供科学依据。
