浓缩过程工艺参数自动测控系统

Automatic Measuring and Control System of Thickening Process Parameters

选煤厂煤泥水循环工艺流程参数的控制是煤泥水系统闭路循环自动化的重要组成部分，而浓缩是煤泥水循环的主要过程之一，浓缩机的工作制度决定于流程的需要，其主要控制参数也有所不同。文章介绍处理浮选尾矿的浓缩过程的工艺参数检测方法，控制方法以及ＳＴＤ—总线工业控制计算机实现的控制系统。

Control of water and slurry circuit parameters is the important part of closed-circuit cycle automation for water and slurry circuit in preparation plants, in which thickening is one of the main process.Thickener's working is determined by the process and the main control parameters vary.The paper introduces the detecting and contro method of process parameters in thickening of floated tailingsdam and the control system achieved by STD-bus industrial control computer.
