【摘要】：為了有效抑制氣體爆炸時(shí)產(chǎn)生的沖擊波強(qiáng)度,設(shè)計(jì)加工了內(nèi)部截面為110 mm×80 mm,長(zhǎng)500 mm的爆炸實(shí)驗(yàn)管道,利用高頻動(dòng)態(tài)壓力傳感器,對(duì)比研究了泡沫鎳在管道內(nèi)的安放位置對(duì)甲烷-空氣預(yù)混氣體爆炸的影響。結(jié)果表明:當(dāng)把泡沫鎳鋪設(shè)在管道中間位置時(shí)其對(duì)爆炸超壓的抑制效果最好,其次是放置在管道的尾部,效果最差的是將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.
