Abstract

The invention discloses a method and system for recycling photovoltaic components. The method includes the following steps: removing the frame, the junction box and the glass panel on the photovoltaic module to obtain the preliminary material; cutting the preliminary material to obtain the preliminary material fragment; placing the preliminary material fragment in the Stripping is carried out in a peeling device equipped with a rotary hitting mechanism to obtain a mixture of EVA film fragments, backplane fragments, bus bar fragments, welding ribbon fragments and silicon powder; Board fragments, busbar fragments, and ribbon fragments. The method for dismantling and recycling backplanes, EVA, battery sheets and complete glass of the present invention has the advantages of high dismantling and recycling efficiency, low energy consumption, no environmental pollution, etc., greatly reduces resource waste and waste discharge, and reduces recycling cost, is an environmentally friendly resource recovery 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 ...
