活化水蒸气控制瓦斯爆炸的实验

在自行设计的内径88mm、总长1600mm的小型瓦斯爆炸控制实验装置上,采用高速摄录分析系统,对活化水蒸气控制瓦斯爆炸进行了实验研究。普通水经过高能物理方法处理后,可转变成比普通水分子团直径小一半的由5~8个水分子组成的小分子团活化水,然后通过水蒸气发生器转化成活化水蒸气,在瓦斯爆炸过程中起到了均相等径抑制作用和纳米活化控制作用。实验结果表明,加入活化水蒸气后的瓦斯爆炸感应期明显延长,火焰在管道中的传播时间延长,火焰平均传播速率减小,控爆效果明显提高。 

Experiment study on controlling gas explosion by active steam

The detonation propagation of active steam controlling gas explosion has been studied on a small-sized experimental installation with 88 mm in inner diameter and 1 600 mm in length.And character of flame propagation was monitored by high speed photographic instrument.Treated by high-power physical methods,common water can change into active water with small molecules group;the active water,whose diameter is half as that of com-mon water molecule,is composed of five to eight water molecules,then it witch to active steam after going through steam generator,functions as homogeneous-phase,equal-diameter inhibitor and nanometer-active controller during procedure of gas explosion.The result shows that when activation steam is injected into experimental pipe,induc-tion period and flame propagation time in the pipe of gas explosion was prolonged,and mean rate of flame propa-gation were reduced remarkably.The effect of controlling explosion of activation steam is high in comparison with that of common steam.
