摘　　要：循环冷却水在长期运行过程中由于蒸发、浓缩,易在热力设备表面积盐、结垢,而水中碱度大小能够反映循环冷却水水质工况.以电位滴定法为基础,C8051F020单片机为核心研制的循环冷却水在线碱度自动分析仪,通过连续运行实时监测循环冷却水的碱度,测量结果误差小于±3%,满足现场复杂的水质要求.Because of evaporation and concentration,Recirculation cooling water is easy to deposit salt and scale on the surface of thermal equipment during long-term flow.And the alkalinity of water can indicate the water quality of recirculation cooling water.To meets the field requirements,based on the potentiometric titration and C8051F020 MCU,Recirculation cooling water online alkalinity automatic analyzer was developed,which can monitor the alkalinity of recirculation cooling water in real time,and the measurement error is less than±3%.
