【摘要】：为了有效抑制气体爆炸时产生的冲击波强度,设计加工了内部截面为110 mm×80 mm,长500 mm的爆炸实验管道,利用高频动态压力传感器,对比研究了泡沫镍在管道内的安放位置对甲烷-空气预混气体爆炸的影响。结果表明:当把泡沫镍铺设在管道中间位置时其对爆炸超压的抑制效果最好,其次是放置在管道的尾部,效果最差的是将多孔材料放置在管道的前部。
[Abstract]:In order to effectively suppress the shock wave intensity produced by gas explosion, an explosive experimental pipe with an internal cross section of 110 mm 脳 80 mm and a length of 500 mm was designed and manufactured, and a high frequency dynamic pressure sensor was used. The effect of the location of nickel foam in the pipe on methane-air premixed gas explosion was studied. The results show that when the foam nickel is laid in the middle of the pipeline, it has the best suppression effect on the explosion overpressure, followed by the tail of the pipe, and the worst effect is to place the porous material in the front part of the pipe.
