The field of renewable resource recycling mainly refers to the recycling technology and equipment of renewable resources such as scrap steel, scrap non-ferrous metals, scrap plastics, scrap tires, waste paper, waste electrical and electronic products, scrap power batteries of new energy vehicles, waste glass, scrap photovoltaic modules, and scrap wind turbine blades.
The photovoltaic modules of the retired photovoltaic panels are disassembled by classification, and the reusable silicon, silver, copper, aluminum and other materials are recovered, turning the “retired” photovoltaic modules into “treasures”. At present, there are three ways to treat the solid waste of waste photovoltaic modules: one is to downgrade or repair them; the second is to remove the frame and junction box and use them as fillers in the construction field or incinerate them as garbage; the third is to recycle and reuse. Physical separation method for recycling photovoltaic modules: first remove the aluminum frame and junction box of the module, then crush the frameless module, separate the tin-coated solder strip and glass particles, and then grind the remaining part, and use the electrostatic separation method to obtain metal, silicon powder, backboard particles and EVA particles.
Photovoltaic panel recycling equipment waste photovoltaic module recycling technology. Increase the intensity of research on the recycling and utilization technology of new components, such as flexible components, MWT components (involving the recycling and processing of components without solder strips), and heterojunction components (involving the recycling and processing of indium compounds). Second, strengthen the research on the recycling and processing technology of production raw materials. In addition to the recycling and processing of waste components, in the production process of photovoltaic products, a certain proportion of materials such as films, backboards, frames, and glass are also scrapped, and it is also necessary to strengthen the research on the recycling and processing technology of scrapped materials. Third, improve the green development level of recycling and processing work. Promote energy conservation and green emission reduction in the industrial processing of waste components to achieve harmless treatment. Fourth, strengthen the green design of photovoltaic products. Consider the subsequent recycling and processing issues from the material selection and product design end, such as developing packaging materials that are more conducive to the separation of films, backboards, glass, etc.
