摘要:

氢氧化钾装置电解工序中阳极液槽的液位原设计在阳极液泵出口安装调节阀进行控制,但阳极液槽液位与阳极液泵备用泵不存在联锁关系,当阳极液泵出现故障时,备用泵无法及时启动,存在因氯气泄漏而导致氢氧化钾装置停车的风险。针对存在的问题,重新设计了阳极液泵控制方式,使存在的问题得到有效解决。

Abstract:

In the original design, the liquid level of the anolyte tank in the electrolysis process of the potassium hydroxide production unit is controlled by the regulating valve installed at the outlet of the anolyte pump, but the anolyte tank level and the backup pump for anolyte pump do not have an interlocking relationship, so when the anolyte pump fails, the backup pump cannot be started in time, and there is a risk that the potassium hydroxide production unit will shut down due to chlorine leakage. In order to solve this problem, the anolyte pump control method is redesigned, and the existing problem is solved effectively.
