电极自动清洗装置的简介与实践

Introduction and Practice of Automatic Electrode Cleaning Device

在烟气制酸,废酸废水处理系统工序中,pH电极的在线应用较为广泛。为了满足工艺条件的需求,经常会对pH值进行连续在线监测及控制。由于生产现场的特殊工况,电极的检测球泡浸在被测溶液中,经常会发生结垢的现象;导致测量数据的失真或无法获取检测值,这种现象是电极使用中的常见现象同时也是PH电极在实际使用中的瓶颈问题。本文针对电极检测中出现的问题进行了详尽的分析、论证、汇总,提出了相应的解决办法及改进优化措施。

pH electrode is widely used in flue gas acid production and waste acid wastewater treatment system.Continuous online monitoring and control of pH values are often carried out to meet the requirements of process conditions.Due to the special working conditions in the production site,the detection bulb of the electrode is immersed in the tested solution,and scaling often occurred.The distortion of the measured data or the failure to obtain the measured value is not only a common phenomenon in the use of the electrode but also a bottleneck problem in the actual use of the pH electrode.In this paper,the problems in electrode detection are analyzed,demonstrated and summarized in detail,and the corresponding solutions and improvement and optimization measures are put forward.
