摘要:随着水资源的缺乏和水污染的日益严重,废水的过滤与分离能很好的解决废水的处理与重复利用的问题,实现良好的经济效益和社会效益。但传统的过滤分离设备占地空间大,连续生产能力低,自动化程度不高,造成人力物力财力的浪费。本文以自行开发50m3/h处理量全自动白清洗过滤器为基础,提出了全自动自清洗过滤器的各操作参数的设计思想和方法,并建立了过滤过程中过滤器的模型,借此确定控制系统的控制参数。主要工作内容如下;研制设计了一台处理量为50m3/ h、工作压力为1.6-2.5 Mpa,要求过滤精度为0.1-200μm,过滤总面积为10㎡,电动机功率为5.5KW,工作温度为-5℃-105℃的全自动自清洗过滤器。该过滤器在运行过程中无须停运以清洗过滤元件,整机体积较小,精度可调节,适合于各类工业生产。本文给出了这种过滤器的整体设计方法以及设计图纸,并对过滤器内部过滤机理进行分析,讨论了几个过滤参数,并应用于过滤器控制系统设计之中。

Abstract:As short of water resource and more and more serious situation of water pollution, filtration and separation have been the best way to settle the problem of Reuse of waste water and realization of well economy benefit and social benefit.But there are several disadvantages in these raditional filters such as great volume,discontinuous production, lack of automation, great waste of manpower, materialresources, financial. Based on design of automatic self-cleaning filter on industrial scale (50 m3/h), the design and optimization procedures of several operation parameters are presented and a model of filter is obtained as well,then to calculate control parameters of control system.The main research contents are following as:A auto control self-cleaning filter on industrial scale( 50m 3/h) , work pressure(1.6-2.5Mpa) , filtration accuracy(0.1-200μm), filtration surface(10㎡) , Motor power(5.5 KW) and work temperature(-5 ℃ - 105 ℃)has been designed . auto control self-cleaning filter drive itself to clean completely by its pressure of filtrated liquid and without stop.Volume of the filteris so little and precision can be modulated to fit for kinds of industry produce. In this paper, a suit of drawing and design procedures of such filter has been given.Mechanism during filtration in the filter has been studied are obtained
