摘要： A vacuum purge system is provided to protect the vacuum pump (10) from becoming flooded with liquid that on occasion is purged with vapors from process equipment. The liquid is trapped in a vessel and then evaporated and exhausted through the vacuum pump (10) as vapor. Evaporation of trapped liquid is effected by reducing or stopping the purge stream to the trapping vessel while continuing to operate the vacuum pump, thereby reducing the absolute pressure within the vessel. Evaporation of liquid can also be effected by supplying heat to the trapped vessel, either in cooperation with or instead of the pressure reduction. Use of a programmable logic controller enables a cyclic operation that traps liquid from entering the pump, removes the trapped liquid as vapor, and then resumes normal purge operation.
摘要翻译：提供真空吹扫系统以保护真空泵不被液体淹没，有时用过程设备的蒸气吹扫。将液体捕获在容器中，然后蒸发并通过真空泵作为蒸气排出。捕集的液体的蒸发通过在继续操作真空泵的同时将吹扫流还原或停止到捕集容器来实现，从而降低容器内的绝对压力。液体的蒸发也可以通过与被压缩的容器供热来实现，或者与减压相配合或代替减压。使用可编程逻辑控制器可以进行循环操作，捕获液体进入泵，将蒸汽中的被捕获的液体除去，然后恢复正常的清洗操作。
