Design of detection and analysis system of flocculating sedimentation of thickener

  • 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.
