摘　　要：在60000m^3/h空分设备开车过程中,蒸汽喷射器中的水气回流进入精氩塔底部出口管线,导致发生精氩塔底部管道堵塞故障。通过外接气源对精氩塔进行单体加温,实施管道反向吹扫,有效排除了故障。介绍外接气源的管道安装和加温流程,阐述精氩塔单体加温的注意事项。During starting of 60000m^3/h air separation plant,water vapor from the steam injector returns to the outlet pipeline at bottom of refined argon tower,which results in the fault of pipeline blocking at bottom of the refined argon tower.The refined argon tower is subjected to the single-heating by the external gas,and pipeline is reversely purged,an process are Keywords d thus the fault is effectively eliminated.The installation of pipelines for the external gas and the heating outlined,and the instructions to single-heating of the refined argon tower are described.
