乙炔气瓶不能倒放的原因 | 2011-11-14 15:34:00

乙炔气瓶不能倒放的原因

     乙炔气瓶为能多装乙炔在气瓶中装有丙酮,倒放时丙酮会沉入减压阀、皮管、等阻塞乙炔气通路,容易产生回火,发生燃爆事故。另外气瓶阀门是最脆弱的,当瓶阀折断时,瓶内的高压气体,突然喷出使气瓶向相反方向猛冲,撞到人体造成人身伤亡,撞到机器造成机器损坏,与空气形成爆炸性气体混合气,遇到明火发生爆炸。
     乙炔是一种不稳定的化合物,当压力超过两个大气压时能分解,并放出大量的热,同时由于压力的增高,使其余乙炔气全部分解产生爆炸;但是乙炔气瓶中装有丙酮,在15摄氏度时,1个体积的丙酮能溶解23.5个体积乙炔,当压力为16个大气压时可溶解360个体积乙炔,所以在乙炔瓶中要装有丙酮。
     乙炔瓶中还装有活性炭,孔率为75%,当乙炔压入气瓶后溶于丙酮,并分布在活性炭的细孔中,这些细孔迂回曲折且细小,形成无数细孔滴,乙炔分子被分离,即便一小部分分子分解,不会扩展到其他部分分解。
