Jiangxi Mingxin, as a professional enterprise in the research and development of high-end environmental protection equipment, has a complete system of single-sided glass recycling equipment for waste solar photovoltaic panels. The core includes a photovoltaic panel aluminum frame dismantling machine, a glass separation device, a battery cell crushing and screening equipment, and a supporting dust collection and purification system, which can cover the entire process of dismantling and material separation of waste single glass photovoltaic panels, providing equipment support for efficient recycling.
In the recycling process, the first step is to enter the pre-processing stage: the waste single glass photovoltaic panels are sent to the aluminum frame dismantling machine, which efficiently separates the aluminum frame from the photovoltaic panel body through precise identification and mechanical transmission. The separated aluminum frame can directly enter the metal recycling process; Subsequently, the main body of the photovoltaic panel is cleaned by ultrasonic or spray cleaning to remove surface dirt, and then dried to ensure dryness, laying the foundation for subsequent processing. After the preprocessing is completed, the photovoltaic panel enters the core glass separation stage. The main body of the photovoltaic panel is transported to the glass separation device, which uses mechanical cutting combined with preheating auxiliary technology to first reduce the bonding strength between the glass and the EVA layer. Then, the cutting group cooperates to remove the glass layer by layer, with a glass removal rate of over 98%. After treatment, the glass appears as regular particles with few impurities, and has high market value.
The subsequent processing and environmental protection are equally crucial: after removing the glass, the remaining materials containing battery cells, EVA film, and metal wires enter the crushing and screening equipment. After being crushed to a uniform particle size, copper particles, EVA particles, silicon powder, etc. are accurately separated through multi-layer screening and specific gravity separation technology. The purity of each material meets the requirements for regeneration and can be used for smelting or photovoltaic auxiliary material production. At the same time, the dust collection and purification system operates throughout the entire process, capturing small particles and dust in real time. If back plate treatment is involved, wet grinding is used to avoid gasification of fluorine-containing components, ensuring that the working environment meets standards and achieving "zero pollution" recycling.
