摘要
针对湿法炼锌酸浸出过程中,pH值在线检测难、电极容易受污染等问题,设计了基于STM32的湿法炼锌中pH值在线检测系统。系统实现了自动取样、数据显示、数据上传、电磁阀自动清洗和超声波清洗等功能。解决了恶劣工况下,pH值数据的实时检测问题。现场实验表明该系统性能可靠,数据精准,可实现长时间稳定运行。
In order to solve the problems of difficult on-line detection of pH value and easy contamination of electrode in acid leaching process of hydrometallurgical zinc,an on-line pH value detection system of hydrometallurgical zinc based on STM32 was designed.The system realized the functions of automatic sampling,data display,data uploading,solenoid valve automatic cleaning and ultrasonic cleaning.It solves the real-time detection of pH value data under bad working conditions.Field experiments show that the system performs reliable and gets accurate data.It can realize long-term stable operation.
