Description

Technical Field

[0001] This utility model relates to the field of new energy, and in particular to a device for recycling solar photovoltaic panels. Background Technology

[0002] Solar energy is an important new energy source, and solar photovoltaic power generation has been widely used in my country. Solar photovoltaic panels are the main components for generating electricity using solar energy, but they have a limited lifespan. However, when solar photovoltaic panels are scrapped, only the middle layer of solar cells is discarded; the tempered glass on the front and back is mostly still usable. Therefore, recycling solar photovoltaic panels has significant economic value.

[0003] Solar photovoltaic (PV) panels use a specific photovoltaic adhesive to bond and encapsulate the solar cells to the tempered glass. Currently, the main recycling method for solar PV panels is a high-temperature pyrolysis process. Under high-temperature conditions, the photovoltaic adhesive between the solar cells and the tempered glass decomposes into hydrocarbon gases (C1 to C5) and heavy oil liquids (C6 and above). The total amount of hydrocarbon gases produced by pyrolysis is relatively small, but their composition is complex, and they can be used as fuel, with the heat generated from combustion serving as the heat source for pyrolysis. The heavy oil products (C6 and above) are exported as crude oil products. After pyrolysis, the tempered glass is separated from the solar cells, and the tempered glass is reused in the production of solar PV panels. Summary of the Invention
