Photovoltaic panels contain a large amount of valuable materials. If they are directly discarded, it will cause great waste and pollution. Therefore, vigorously developing the separation technology of waste photovoltaic panels can effectively solve problems such as resource shortages and environmental pollution. According to the structural characteristics of photovoltaic panels, this study proposed physical crushing pretreatment of photovoltaic panels. The removal of photovoltaic panel glass and the enrichment of silicon at different temperatures and different crushing times were investigated. The results show that during the crushing process, the photovoltaic panels are separated along the interface of the glass-silicon-based battery, with a certain selectivity.
Waste photovoltaic panel assembly Photovoltaic panel crushing recycling and disposal equipment system Photovoltaic panel recycling and processing process:
The first step is to disassemble the assembly;
The second step is to disassemble and remove the backplane and wires;
The third step is to crush the assembly and remove the tempered glass on the outside;
The fourth step is to pyrolyze. The main purpose of this step is to dissolve EVA; the last step is extraction to take out the valuable metals and silicon materials in the assembly.
Features of the complete set of equipment for the crushing, recycling and disposal of waste photovoltaic panels:
1. Feeding at the front end, collecting at the tail end, and automatically completing the sorting. One person can operate the whole set of equipment;
2. Sealing throughout the process, filtering dust, and not polluting the environment;
3. Vibration + wind sorting;
Photovoltaic panel processing and recycling equipment At present, photovoltaic panel crushing and recycling equipment takes the circular economy as the starting point, fully utilizes the excellent stability of photovoltaic panel materials, and uses physical heating to destroy the affinity of the material surface, so that the adhesive layer between the glass and the backboard is disassembled and separated, and then recycled separately by grinding. Most of the materials of photovoltaic components are recyclable materials. Recycling photovoltaic components can be recycled and reused, which can save resources, reduce the exploitation of primary resources and reduce the energy consumption of resource extraction, thereby reducing the impact and damage to the ecological environment.
