Design and application of automatic adding chemical system for coal slime water thickener
Flocculation settling is an important link in the treatment of slime water.To solve of the problems in process of adding chemical for flocculating settling,an automatic adding chemical system for coal slime water thickener is designed.The flocculation effect of clarified water layer,intermediate water layer,precipitate layer,and overflow water quality data are detected in real time to correct and adjust the dosage,and that realize accuracy control of automatic adding chemical system for coal slime water thickener.Meanwhile,the press rake can be avoid by the bottom flow concentration detection,the appropriate stop time of filter pressing can be identified by detecting small flow of filtrate water,and the breakdown of frame and the leak of filter can be timely judged by detecting particle concentration of filtrate water.The above methods realize intelligent and efficient operation of the press filter.
