Problems solved by technology

However, various materials obtained by high-temperature heat treatment, such as battery sheets and glass, are not only severely crushed, but also prone to loss and energy consumption in the process, that is, the recovery rate is low and the cost is high; the chemical dissolution reaction takes about 7 days, and the cycle is long. Low processing efficiency

Abstract

The invention discloses a photovoltaic module recovery method. The method comprises the steps of placing a frameless photovoltaic module in a film peeling device, and peeling off a back plate of the frameless photovoltaic module at a first preset temperature to obtain a back plate and the peeled photovoltaic module separated from the back plate; and placing the peeled photovoltaic module in a high-temperature pyrolysis device, and pyrolyzing an adhesive film layer in the peeled photovoltaic module at a second preset temperature to obtain the separated battery piece and substrate. According tothe photovoltaic module recovery method, the back plate of the frameless photovoltaic module is peeled off to obtain the separated back plate and the peeled photovoltaic module, then the peeled photovoltaic module is pyrolyzed, and the adhesive film layer in the peeled photovoltaic module is completely pyrolyzed to obtain the battery piece and the substrate, so that the frameless photovoltaic module is completely separated and the complete and separated back plate, battery piece and substrate are obtained, and the recovery of the photovoltaic module is achieved; and the recovery rate is high,the cost is low, and the recovery processing speed is high.

Description

technical field [0001] The present application relates to the technical field of photovoltaic module recycling, in particular to a method for recycling photovoltaic modules. Background technique [0002] Solar energy is a green and clean energy that is free to use, has unlimited reserves, and does not generate any waste water or waste residue pollutants during use. Therefore, the photovoltaic industry has developed rapidly in recent years. With the development of the photovoltaic industry, effective recycling of waste photovoltaic modules has become an issue of increasing concern to photovoltaic companies. [0003] The existing photovoltaic module recycling technology generally decomposes and recycles photovoltaic modules through high-temperature heat treatment and chemical treatment. Among them, the high-temperature heat treatment is to remove the organic materials in the crushed photovoltaic modules or complete modules by incineration, so as to separate the battery sheet ...
