Abstract

The aim of this paper is to carry out an experimental analysis of a triboelectrostatic separation device constituted of two “back-and-forth” moving horizontal plate electrodes supplied by two high-voltage DC supplies of opposite polarities. The experiments were performed using samples of micronized white pure virgin PolyVinyl Chloride particles (WPVC) and gray PolyVinyl Chloride particles (GPVC) of average size 100 µm. Moreover, a homemade method was developed to estimate the purity of the separated products. It was deduced that the separation outcome, in terms of recovery and purity, is efficient and depends on several factors: the high-voltage level, the movement speed of the electrodes, the fluidization rate and the composition ratio of the granular mixture.

摘要

本文的目的是对由两个“来回”移动的水平板电极构成的摩擦静电分离装置进行实验分析，该电极由两个相反极性的高压直流电源供电。使用平均尺寸为 100 µm 的微粉化白色纯原始聚氯乙烯颗粒 (WPVC) 和灰色聚氯乙烯颗粒 (GPVC) 样品进行实验。此外，还开发了一种自制方法来估计分离产品的纯度。据推断，就回收率和纯度而言，分离结果是有效的，取决于几个因素：高压水平、电极的移动速度、流化率和颗粒混合物的组成比。
