摘要/Abstract

摘要： 为了提高废旧光伏电池板中铜(Cu)与硅(Si)的分选效率,寻求高压静电分选的最佳效率因素.通过单因素影响实验,探究了电压(U)、转辊转速(n)、电晕电极间距(S)和电晕电极角度(θ)对Cu与Si分选效率的影响;利用Minitab软件进行全因子实验设计,筛选并确定了影响因素中对Cu和Si的分选效率有显著影响的主效应和交互作用,并通过响应优化对Cu的分选效率进行了优化,得到Cu的最佳参数为U=20 kV、n=65 r/min、S=90 mm、θ=-10°.在最佳参数条件下,进行了验证实验,Cu分选效率达到了97.91%,得到了良好的优化效果.

Abstract: In order to improve the separation efficiency of copper(Cu)and silicon(Si)in waste photovoltaic panels, the optimal efficiency factors for high-voltage electrostatic separation were explored. Using the single factor impact experiment, the separation efficiency of Cu and Si under the four factors of voltage(U), speed(n), electrode spacing(S)and corona electrode angle(θ)were discussed. And Minitab software was used to screen all-factor experimental design and establish the main effect and interaction of the influencing factors on the separation efficiency of Cu and Si. The separation efficiency of Cu was optimized by response optimization. The optimal separation efficiency of Cu was set to U=20 kV, n=65 r/min, S=90 mm, θ=-10°. Under the optimal settings, verification experiments were carried out. The average separation efficiency of Cu reached 97.91%. The optimization results were obtained.

Key words: waste photovoltaic panels, high voltage electrostatic separation, separation efficiency of Cu, all-factor experimental design
