Abstract

The invention discloses a method for decomposing and recycling a photovoltaic component. According to the method, glass panel particles, ethylene-vinlacetate (EVA) particles, backboard particles and silicon particles are recycled from the photovoltaic component subjected to border and junction box removal by using methods for shearing, squeezing and shearing, grinding at low temperature, vibrating and screening, and the like. Compared with a method for decomposing and recycling the photovoltaic component by adopting thermal treatment and chemical treatment in the prior art, the method for decomposing and recycling the photovoltaic component has the advantages that: the photovoltaic component is decomposed and recycled by adopting mechanical methods for crushing, grinding at low temperature, vibrating and screening, and the like, thermal treatment is not required during treatment, and the energy consumption is relatively low; and furthermore, according to the method for decomposing and recycling the photovoltaic component, chemical reagents are not used, so that secondary pollution to the environment is avoided, and the method is relatively environment-friendly. The invention also provides a device for decomposing and recycling the photovoltaic component.

Description

technical field [0001] The present invention relates to the technical field of photovoltaic module recycling, and more specifically, to a method for decomposing and recycling photovoltaic modules, and to a device for decomposing and recycling modularized photovoltaic modules. Background technique [0002] In the context of frequent shortages of non-renewable energy sources such as coal and oil, photovoltaic power generation has developed rapidly as a new energy source. According to statistics, the global solar cell industry increased by 17 times in the 10 years from 1994 to 2004. At the same time, the newly installed capacity of photovoltaics in the world reached 17GW in 2010, an increase of 132% from 7.3GW in 2009. With the large-scale application of photovoltaic modules, it is inevitable to face the problems of product upgrades and product life expiration. In the general environment, the design service life of photovoltaic modules is about 25 years, and the upgrading of p...
