废氯气吸收系统装置优化

Optimization on waste chlorine absorption system

介绍废氯气吸收系统的生产工艺原理。针对实际生产中存在的问题和隐患——循环槽顶部平衡管对空,废氯气吸收气相总管分支管线被腐蚀,废氯气吸收气相总管中冷凝氯水,废氯气吸收系统负压水封高等,提出优化改造措施:将一级碱液循环槽一键切罐,钛风机远程启动,增加游离碱在线分析仪。改造后,降低了人员的劳动强度,有效保证了装置的安全稳定运行。

The production technology principle of waste chlorine absorption system was introduced. The system had the following problems and hazards in practical production： the balance tube at the top of absorption, and the height of negative pressure water seal for waste chlorine absorption system was large. Improvement measures were proposed ： one-key switching of the primary level tank, remote start-up of titanium fan, adding on-line analyzer for free alkali. labor intensity,and ensured safe and stable running of, the system. of alkali liquor circulation The improvement reduced
