Photovoltaic panels are silicon-based photovoltaic modules, mainly composed of tempered glass, ethylene vinyl acetate (EVA), cells and junction boxes. The role of tempered glass is to protect the main body of power generation, that is, the cells. EVA is like glue to fix the tempered glass and cells together. The junction box is used as a current transfer station to protect the entire solar panel. There is cloth inside With copper wire. Although from the perspective of material composition, used solar panels can be said to be treasures everywhere and have great recycling value. These materials can be separated one by one and processed separately, but it is a time-consuming, labor-intensive and technologically demanding process. If you want to realize recycling, you must first dismantle the junction box and peel off the copper wires so that the copper can be recycled after purification. Then the glass plate is ground off from the EVA. The ground glass powder can be reused in industry and construction. Use, and then recycle the silicon in the cells.
SUNY GROUP's photovoltaic panel recycling and processing equipment technology utilizes physical processing methods, selective crushing and other advantages to crush, dissociate and recover high-value components of solar panels. The entire treatment process does not use chemical reagents, and no waste water, waste liquid, waste gas and dust are generated, achieving a harmless treatment process, high recovery yield and low resource consumption. This technology breaks through the technical bottleneck of high energy consumption and high pollution of the original recycling method. It has the advantages of small environmental pollution, low energy consumption, and high economic returns. It can provide new solutions for the environmental recycling of discarded solar panels in my country and has great significance. market space.
