摘　　要：针对浓缩机药剂添加自动化闭环控制需求,设计了一种浓缩机絮凝沉降检测分析系统。当浓缩机中煤泥水浓度低于5%时,该系统采用CN141浊度计检测絮凝沉降效果,浊度计直接输出4～20mA的电流信号送微处理器处理;当煤泥水浓度为5%～35%时,该系统采用微电容阵列传感器检测絮凝沉降效果,检测结果经放大滤波后送微处理器处理。实际应用表明,该系统能够准确、及时地检测出浓缩机絮凝沉降效果,实现了浓缩机絮凝剂添加的闭环控制。In view of requirement of automatic closed-loop control for agent addition of thickener,a detection and analysis system of flocculating sedimentation of thickener was designed.The system uses CN141 turbidimeter to detect effect of flocculating sedimentation when concentration of slime water is less than 5%,and the turbidimeter outputs 4-20 mA current signal to microprocessor directly.The system uses micro-capacitor array sensor to detect effect of flocculating sedimentation when concentration of slime water is 5%-35%,the detected result is sent to microprocessor after amplified and filtered.The actual application shows that the system can detect effect of flocculating sedimentation of thickener accurately and real-timely and realizes closed-loop control of flocculant addition of thickener.
