While photovoltaic power generation is developing rapidly, it is also facing the problem of aging, retirement and recycling of solar panels. The service life of solar panels is only 20 to 30 years. The International Renewable Energy Agency predicts that my country’s retired photovoltaic modules will reach 1.5 million tons in 2030. How to harmlessly treat and recycle solar panels has become a hot issue of concern to the industry and the environmental community.
The recycling process of photovoltaic panels can effectively crush and dissociate each component (glass, silicon powder, valuable metals and polymer materials), providing a new crushing and recycling method for solar panels with laminated structures. The entire treatment process does not use chemical reagents, and no wastewater, waste liquid and dust are generated; the crushing and separation process occurs in water, achieving harmless treatment (tap water is recycled after filtration), and the recovery yield and quality of each component are high, breaking through the technical bottleneck of high energy consumption and high pollution of the original recycling method. This project provides a large-scale, low-energy, low-cost photovoltaic module recycling technology, which has important social, livelihood and economic benefits for the recycling of solid waste resources and the creation of a photovoltaic green industry chain.
The ideal recycling situation of photovoltaic panel separation equipment is as follows: the photovoltaic panels first enter the frame disassembly part, and the glass adhesive strips after the frame disassembly are also cut and cut. Then the panel materials finally enter the glass recycling facility and the copper wire is stripped off. Then, the photovoltaic panel glass separation equipment tears the glass plate without destroying the interlayer components of the photovoltaic panel. In this link, a shiny glass-like powder can be recycled, also called broken glass. This material can be used as building materials or other industrial applications. After that, the panel materials begin to be crushed and sorted, copper separation, plastic separation, and silicon separation.
