Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste photovoltaic panel processing, in particular to a waste photovoltaic panel oxygen-free pyrolysis recycling device. BACKGROUND

[0002] Under the background of the global decrease in fossil fuels, solar power generation, as a clean and renewable energy form, is gradually gaining widespread attention and application. Photovoltaic panels, as the core component of solar power generation, are self-evidently important. However, with the rapid development and widespread application of photovoltaic technology, the problem of waste photovoltaic panels has become increasingly prominent, becoming a major challenge to the sustainable use of resources.

[0003] Photovoltaic panels are mainly composed of tempered glass, single / multicrystalline silicon cells, and aging-resistant back panels, and are fixed and bonded by EVA glue. Among them, the silver grid lines, tin dioxide, indium, gallium, germanium, and other rare metals in the cells have high recycling value, so the recycling of photovoltaic panels is particularly important.

[0004] However, in the field of photovoltaic panel recycling, the challenges of automation technology and the problem of tail gas treatment have become two major obstacles to its development.

[0005] Firstly, the recycling process of photovoltaic panels requires high levels of automation technology. Existing physical separation methods, such as crushing and cutting, while being inexpensive and allowing direct recycling of glass, are insufficient in the recycling of high-value materials such as high-priced metals. In addition, chemical treatment and incineration methods, while able to extract metal substances, are complex, costly, and pose environmental pollution risks, making it difficult to achieve efficient and environmentally friendly recycling goals.

[0006] Secondly, the problem of tail gas treatment is an important aspect of the photovoltaic panel recycling process that cannot be ignored. In the incineration process, aluminum alloy frames, copper wires, cell pieces, and tempered glass can be completely separated, but the plastic parts of the back panel will produce a large amount of waste gas and dust during the incineration process, posing a serious threat to air quality. Existing tail gas treatment technologies cannot completely solve this problem, making environmental protection during the photovoltaic panel recycling process a difficult problem that needs to be solved.

[0007] In summary, the automation challenges and tail gas treatment problems in the field of photovoltaic panel recycling have become important factors hindering its sustainable development. Therefore, developing efficient and environmentally friendly photovoltaic panel recycling technologies and equipment has become a technical problem that needs to be solved urgently. In view of the above problems, there may be existing technical means to solve them in the prior art, but the present application wants to provide an alternative or replacement technical solution.
