多台中煤浓缩机絮凝剂自动添加系统

摘要

In order to resolve the existing problems of adding flocculant such as poor effect of preparation, unreliable detection link, and poor real-time, the paper put forword a design scheme of auto-adding system of flocculant of medium-coal thickeners taking auto-adding system of medicament of medium-coal thickeners of Tianzhuang coal preparation plant as example. It introduced control principle, overall design, and software design of the system in details. The system can realize automatic control of adding volume of flocculant through detecting flow and turbidity of slime water. The practical application showed that the system realizes efficient and saving production and zero discharge of slime water, increases utilization rate of slime water, and eliminates pollution caused by slime water of preparation on environment.%针对当前絮凝剂投放存在制备效果差、检测环节不过关、实时性差等问题,以田庄选煤厂的多台中煤浓缩机絮凝剂自动添加系统为例,文章提出了一种多台中煤浓缩机絮凝剂自动添加系统的设计方案,详细介绍了该系统的控制原理、总体设计及软件设计.该系统通过对煤泥水流量及浊度的检测实现了絮凝剂投放量的自动控制.实际应用表明,该系统实现了高效、节约型生产方式以及煤泥水的零排放,提高了煤泥水的利用率,消除了煤泥水对环境造成的污染.
