Re:乙炔气割枪回火的预防 | 2013-2-4 8:25:48

乙炔气作为割枪燃气，在船舶制造修理及钢结构行业应用广泛。乙炔气割枪具有预热速度快、起割容易等优点，尤其方便用于切割生锈的，带有氧化皮或严重污染的金属板和薄板。但另一方面，乙炔属于易燃易爆气体，与氧气或空气混合，遇火源会剧烈燃烧甚至爆炸。而且在一定的温度和压力条件下，乙炔会分解生成碳黑和氢气，反应释放大量热能，会导致爆炸发生。乙炔还能在一定条件下聚合生成链状或环状结构的有机化合物，如在400℃~500℃下，可以特殊性聚合反应生成苯。乙炔聚合时会放热，温度越高，聚合速度越快，热量的积聚会进一步加速聚合，同时发生聚合物分解，最终引起爆炸。
回火是使用乙炔气割枪进行气割作业时最容易发生的事故类型之一，是乙炔气体火焰进入割枪喷嘴内逆向燃烧的现象，特征是火焰突然熄灭，割枪内发出急速的“嘶嘶”声。在使用乙炔气割枪进行切割的过程中，如果操作不当，很可能发生回火事故，轻则损坏设备工具，重则可能发生爆炸，威胁操作人员的生命安全。回火引起的事故存在很大的隐蔽性，往往不容易找出事故发生的确切原因。笔者结合多年来在船舶企业安全管理一线的工作经验，对造成乙炔割枪回火的原因进行分析，并提出回火的预防措施。
