Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The photovoltaic module recovery device adopted in the embodiment of the present invention includes a shearing machine, a mace thresher, a metal trap, an antistatic vibrating screen and a cyclone separator connected in sequence.

[0032] The shearing machine is used to fragment the photovoltaic cells after removing the frame, junction box and glass panel to obtain the primary material fragments; the thresher is used to peel off the silicon cell sheets on the primary material fragments to make the EVA Separation of film, back plate, solder strip, bus bar and silicon battery sheet to obtain a mixture of silicon powder ...

Abstract

The invention discloses a photovoltaic module recycling method and system. The method comprises the following steps: removing a frame, a junction box and a glass panel on a photovoltaic module to obtain primarily-separated materials; shearing the primarily-separated materials to obtain primarily-separated material fragments; placing the primarily-separated material fragments in a stripping deviceprovided with a rotary striking mechanism and performing stripping to obtain a mixture of EVA film fragments, backplane fragments, bus-bar fragments, solder strip fragments and silicon powder; and sorting out silicon powder, EVA film fragments, backplane fragments, bus-bar fragments and solder strip fragments through a sorting device. The method for disassembling and recycling the backplane, EVA,battery cells and complete glass has the advantages of high disassembling and recycling efficiency, low energy consumption, no environmental pollution and the like. Resource waste and waste dischargeare greatly reduced, and the recycling cost is reduced. The method is an environment-friendly resource recycling method.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module recycling, in particular to a method and system for recycling photovoltaic modules. Background technique [0002] In recent years, the photovoltaic industry has developed rapidly as a clean and renewable energy source. The scale and market application of my country's photovoltaic industry have reached the first place in the world. Photovoltaic modules are made of glass, packaging materials, cells, backplanes, aluminum frames, junction boxes, silica gel and other main materials, which are packaged according to a certain production process, and can achieve a certain output power and output voltage under certain lighting conditions. . The life cycle of photovoltaic modules is mostly 25-30 years, and the upgrading of products will make the actual service life of photovoltaic modules much shorter than its designed service life, and a large number of photovoltaic modules will be eliminated ...
