摘　　要：介绍了干吸工序自动串酸系统存在问题及解决措施,针对泵槽液位计、酸浓度分析仪、串酸调节阀、自动串酸模式存在的问题做了相应改进,并整定了调节回路PID参数。实践证明此次改造是成功的,改进的自动串酸系统运行良好。Problems existing in the automatic sulphuric acid crossflow system of drying and absorption section and corresponding measures are introduced. Liquid level transmitter of pump tank, concentration analyzer, crossflow regulating valve and automatic crossflow model were improved and PID parameters of regulating loop were turned. The retrofitting proved successful and the automatic sulphuric acid crossflow system operated well.
