氯化氢降膜吸收塔正压的原因

摘要

The falling film absorption technology of hydrogen chloride is introduced.The causes of positive pressure formed in falling film absorption tower during its running are analyzed from 3 aspects of excessive production load, excessive vacuum caused by injection pump suction, and packing blockage of falling-film absorption tubes.Solutions are proposed.%介绍了氯化氢降膜吸收工艺，从生产负荷过大、喷射泵抽吸形成的负压超标和填料堵塞降膜吸收管3个方面分析了降膜吸收塔运行过程中出现正压的原因，并提出了解决办法。
