摘要
光伏组件中的背板是一种含氟塑料,回收利用价值低且易产生环境污染,需要提前去除集中处理。为了研究超声椭圆振动切削(UEVC)去除退役光伏组件含氟背板的优越性,开展了超声椭圆振动切削(UEVC)与常规切削(CC)的对比仿真实验,并针对UEVC进行以切削速度、切削深度、切向振幅和频率为变量的单因素仿真实验。仿真结果表明:UEVC过程中,切削温度和切削力与切削速度和切削深度成正相关,与切向幅值和频率成负相关。其中,切削力受到切削深度的影响最显著。相对于CC而言,UEVC能够明显降低切削力和切削温度,其中,主切削力降低43%,切削温度降低11%,是一种在无污染的前提下去除退役光伏组件含氟背板的有效加工方式。
The backplane in the photovoltaic module is a fluorine-containing plastic,which has low recycling value and is easy to produce environmental pollution,and needs to be removed in advance for centralized treatment.In order to study the advantages of ultrasonic elliptical vibration cutting(UEVC)in removing the fluorine-containing backplane of retired photovoltaic modules,simulation experiments are carried out to compare UEVC with conventional cutting(CC),and single factor simulation experiments with cutting speed,cutting depth,tangential amplitude and frequency as variables are carried out for UEVC.The simulation results show that the cutting temperature and cutting force are positively correlated with cutting speed and cutting depth,and negatively correlated with tangential amplitude and frequency during UEVC.The cutting force is most significantly affected by the cutting depth.Compared with CC,UEVC can significantly reduce the cutting force and cutting temperature,in which the main cutting force is reduced by 43%,and the cutting temperature is reduced by 11%,which is an effective processing method to remove the fluorine backplane of decommissioned photovoltaic modules without pollution.
