Physical crushing and separation method for processing and utilization of waste photovoltaic modules
The main materials for dismantling scrapped photovoltaic modules are glass, aluminum frames, copper welding strips, plastics, etc. Recycling contributes significantly to carbon emission reduction and is an important means to achieve reuse and reprocessing. In terms of the research and development of physical recycling technology for waste photovoltaic panel structures, the total mass recovery rate is 91.2%, the silver recovery rate is 91%, the silicon recovery rate is 95.1%, and the copper recovery rate is 95.2%; in terms of the thermal decomposition recovery technology studied, the laboratory total mass recovery rate is 90.2%, the silver recovery rate is 93.76%, the silicon recovery rate is 96.27%, and the copper recovery rate is 99%. The photovoltaic panel crushing and recycling equipment line for waste photovoltaic panels can obtain clean whole glass, whole strip welding strips, granular battery cells, and sheet EVA and backplane and other polymer materials through high-pressure grinding of scrapped crystalline silicon photovoltaic modules. Physical crushing process and method; the physical crushing method includes the processing and crushing of grounding boxes, photovoltaic panel frames and photovoltaic panel glass, and photovoltaic panels, which can realize the recovery and collection of valuable metals of various components of waste photovoltaic materials.
