When recycling scales reach 10,000 solar panels, traditional small-scale dismantling methods can no longer meet efficiency and environmental requirements. Instead, there is a need for a comprehensive industrialized technology system. This paper will discuss which technology can you use in the recycling process for 10,000 used solar panels.

What challenges does recycling 10,000 photovoltaic panels present?

The recycling of 10,000 photovoltaic panels faces multiple challenges arising from large-scale operations.

  • At the warehouse management level, the project requires approximately 800 square meters of storage space and professional loading and unloading equipment.

  • Faced with the challenge of mixing photovoltaic modules from different brands, eras, and technological approaches, it is difficult to achieve precise classification and efficient processing.

  • Допълнително, environmental compliance requirements increase significantly with larger processing scales. Wastewater and exhaust gases must comply with more stringent treatment facilities and real-time monitoring systems.

  • Traditional processing methods have shown significant shortcomings when addressing large-scale recycling demands. Specifically, the reliance on manual dismantling proves inefficient, and it takes fifteen workers over forty consecutive days to process ten thousand photovoltaic panels.

  • Освен това, crude and wasteful methods of crushing and landfilling result in waste of over ninety-five percent of resources.

Which technologies are suitable for large-scale solar panel processing?

In the background of recycling large quantities of photovoltaic modules, photovoltaic panel recycling technology should focus primarily on mechanical separation, pyrolytic delamination, and chemical purification.

 

Mechanical Disassembly

Първо, photovoltaic panels undergo mechanical disassembly by оборудване за разглобяване на слънчеви панели, which gradually separates the алуминий frame, junction box, стъкло, and cell layers. Междувременно, the intelligent recognition and sorting system can automatically identify the dimensions and structural type of photovoltaic panels and realize precise classification processing. The system’s processing capacity reaches 80 към 100 modules per hour.

Thermal Delamination

The robust adhesion of the EVA encapsulation layer within photovoltaic panels poses a critical challenge in separating the glass from the solar cells. PV пиролизна технология employs a continuous pyrolysis system to decompose EVA under an oxygen-free environment at approximately 450–600°C. Следователно, this enables the complete separation of the glass substrate from the silicon layer.

After delamination, the solar cells can undergo a chemical wet process to remove surface impurities and residual adhesive.

Common acid and alkali solutions are controlled according to their ratios to achieve efficient desorption. В същото време, this control also minimizes emissions of harmful gases and waste liquids.

Chemical methods play a crucial role in achieving precise separation and surface purification throughout the entire process. Следователно, they provide assurance for safe and environmental disposal.

Purification Process

Recycling of waste liquid through neutralization reactors enables water resource reuse. While the waste gas goes through a cooling tower, activated carbon adsorption tower, and exhaust gas burner for purification and discharge in compliance with standards. Finally, vibrating screen separator и magnetic separation machine classify and recycle the solid residue.
