摘　　要：本文所设计的带式电晕静电分离器是可以选择性分选微粉化废物中含有的导电和非导电成分的产品。试验设计在实验室规模的多功能静电分离器上进行。将线和带之间的距离以及施加的电压调节到允许粒子充电的值,而没有使其在带的表面上运动的电晕。在高压辊型电极(直径30 mm)和接地带状电极之间产生的电场中进行分离。本研究的结论将用于工业带式电晕-静电分离器的最佳设计,用于从废弃电气和电子设备中回收金属和塑料。The belt corona electrostatic separator designed herein can be a selective sorting of conductive and nonconductive products contained in micronized waste. The experimental design was performed on a laboratory scale multifunction electrostatic separator. The distance between the wire and the tape and the applied voltage are adjusted to a value that allows the particles to be charged without a corona that causes them to move over the surface of the belt. Separation was performed in an electric field generated between a high voltage roll type electrode (diameter 30 mm) and a ground strip electrode. The conclusions of this study will be used in the optimal design of industrial belt corona-electrostatic separators for the recovery of metals and plastics from waste electrical and electronic equipment.
