摘　　要：介绍了一起小型制氧制氮设备在工况转换后临时停车过程中发生的主冷物理爆炸事故,经分析得出原因为:残留的液空在主冷冷凝侧的密闭空间吸热蒸发,使冷凝侧超压爆炸。One physical explosion accident occurring in the main heat exchanger of a small scale oxygen and nitrogen plant after condition switch during temporary shutdown process is introduced. On analyzing the cause, it is found that the remaining liquid air in the enclosed space of main condenser＇s condensing side evaporates by absorbing heat, which leads to the overpressure explosion.
