摘　　要：氢氧化钴回收工艺中,pH值是指导生产的关键数据,实际使用过程中pH电极表面易结垢,工艺波动和电极表面易磨损等因素,导致电极易损坏和在线检测数据稳定性降低。为此,公司变更了pH电极的安装位置及检测方式,提高了测量精度和时效性。利用pH值在线检测的数据与自动化控制联锁,可达到降低氧化镁消耗,提高了氢氧化钴回收率,减轻工人工作量,从而产生较高经济效益和社会效益。In the recovery process of cobalt hydroxide,the pH value is the key data to guide the production.In the actual use process,the pH electrode surface is easy to scale,process fluctuation and electrode surface is easy to wear and other factors,leading to easy electrical damage and the stability of online detection data.To this end,the company changed the pH electrode installation position and detection method,improve the measurement accuracy and timeliness.By using the data of pH on-line detection and automatic control interlocking,the consumption of magnesium oxide can be reduced,the recovery rate of cobalt hydroxide can be increased,the workload of workers can be reduced,and higher economic and social benefits can be generated.
