The recycling and treatment of waste crystalline silicon solar cells has not attracted enough attention, and there are problems such as waste of resources and environmental pollution. Because the cells mainly contain important raw materials required in the production process such as silicon, silver, and aluminum, we explore an environmentally friendly circular economy model based on this, and make full use of the metal value in the disposal process of crystalline silicon solar cells to recycle and treat crystalline silicon solar cells, so as to realize the reuse of materials such as silicon, silver, and aluminum.
Photovoltaic panel glass removal machine At present, the number and scale of scrapped solar panels in electronic waste are still insignificant, but their growth rate is very fast. The industry is worried that with the acceleration and deepening of green transformation, the application of solar energy is becoming more and more extensive, and the treatment of a large number of scrapped panels will become an unacceptable burden for the solar energy industry. Many people will wonder, isn’t solar energy a clean energy? How can photovoltaic panels that convert sunlight into electricity pollute the environment? This is because the composition of photovoltaic panels is very complex, interwoven with silicon, aluminum, copper, silver, lead and other materials, like a piece of clothing woven with various silk threads and sewn together with various layers of materials. If you want to recycle, you must first separate the layers of materials, then extract the various silk threads, and then recycle and purify them. Photovoltaic panels are silicon-based photovoltaic components, mainly composed of tempered glass, ethylene-vinyl acetate (EVA), cells and junction boxes. The function of tempered glass is to protect the power generation body, 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, and copper wires are coiled inside. Although from the perspective of material composition, waste solar panels can be said to be treasures everywhere and have great recycling value, these materials can be separated and processed one by one, but it is a time-consuming, labor-intensive, and technically challenging process. To achieve recycling, you must first disassemble the junction box and peel off the copper wire so that the copper can be recycled after purification, and then grind the glass plate from the EVA. The ground glass powder can be reused in industry and construction, and then the silicon in the cell can be recycled.
Photovoltaic panel crushing equipment Let’s take a look at the production line of Ruisek’s waste solar panel recycling and utilization. The photovoltaic panel recycling and processing equipment technology uses the advantages of physical processing methods and selective crushing to crush, dissociate and recycle high-value components of solar panels. The entire treatment process does not use chemical reagents, and no wastewater, waste liquid, waste gas and dust are generated, achieving harmless treatment process, low recovery yield and 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 low environmental pollution, low energy consumption, and high economic benefits. It can provide a new solution for the environmentally friendly recycling of discarded solar panels in my country and has a large market space.
