Equipment and method for disassembling solar cell module

Abstract

The invention provides equipment and a method for disassembling a solar cell module. The equipment for disassembling the solar cell module comprises a low-temperature treatment device, a collecting and conveying device, a grinding and rubbing device and a separating device. According to the equipment, in a low-temperature environment created by the low-temperature treatment device under normal pressure, the non-destructive high-efficiency glue-residue-free disassembly is achieved by utilizing physical characteristics of different thermal expansion and cold contraction, different phase state transition points and the like of a backboard, a lower laid EVA film and an aluminum back surface field coating, and the complete backboard, the complete lower laid EVA film and the upper aluminum backsurface field coating of the solar cell module are obtained. A battery piece and an upper cover EVA film are crushed and disassembled from the glass surface through the grinding and rubbing device, complete glass, silicon wafer particles, metal welding strips, metal bus bars and upper cover EVA powder with low residual glue rate are obtained, and different materials are separated and sorted through the separating device. The environment-friendly disassembly and classified recovery of waste solar cell modules are achieved.

Description

technical field [0001] The invention relates to the field of solar cell recycling, in particular to a device and method for disassembling solar cell components. Background technique [0002] The rapid development of the photovoltaic power generation market requires that the photovoltaic modules after their lifespan, especially the crystalline silicon cell modules and their components (glass, silicon, copper, aluminum, silver, plastic, etc.) that occupy more than 80% of the world market share. Harmless treatment and even recycling can alleviate the shortage of raw materials for photovoltaic devices, and reduce resource waste and ecological environment pollution. [0003] Internationally, the European and Japanese energy industries have carried out in-depth research on photovoltaic module recycling and harmless treatment technologies and management systems, and have incorporated them into regulations and policies. In 2012, the European Union Conference formally changed the "W...
