Abstract

The invention provides a recovery method of a photovoltaic module. The photovoltaic module comprises a metal frame and a junction box, the method comprises the steps that spliting is carried out on the photovoltaic module to obtain the metal frame, the junction box and a to-be-recycled module, the to-be-recycled module is other modules except the metal frame and the junction box in the photovoltaic module; the to-be-recycled assembly is cut by adopting pulse water to obtain a crushing assembly; and sorting is carried out on the crushing assembly, and multiple valuable components are obtained. According to the recovery method, selective separation of the retired photovoltaic module is realized by adopting a pulse water crushing technology, no dust, waste gas or wastewater is generated in the recovery process, no chemical reagent is involved, and therefore the energy consumption is reduced, the recovery efficiency is improved, and secondary production is facilitated.

Description

technical field [0001] The present application relates to the technical field of recycling decommissioned photovoltaic modules, in particular, to a method for recycling photovoltaic modules. Background technique [0002] Solar energy is clean and renewable energy. The development and use of solar energy is an important development direction and industrial layout of my country's energy industry. At present, my country's photovoltaic installed capacity and power generation have ranked first in the world for many years. The service life of photovoltaic modules is 20 to 30 years. While photovoltaic power generation is developing rapidly, it is also facing the problem of aging, decommissioning and recycling of photovoltaic modules. How to harmlessly treat and recycle decommissioned photovoltaic modules has become a hot issue of concern to the international industry and environmental circles. [0003] Decommissioned photovoltaic modules include photovoltaic glass, aluminum frame,...
