Description
Technical field
The present invention relates to a kind of recovery method of crystalline silicon photovoltaic module and devices, belong to technical field of solar batteries.
Background technique
Photovoltaic module is the device for solar energy being converted to electric energy, and working environment is the outdoor environment of exposure, photovoltaic module
Use have certain service life, it is general to require to be 25 years.The valuable resources such as silicon, aluminium, silver, glass in photovoltaic module,
Major part can realize cycling and reutilization by recycling, reduce and exploit to Resources, reduce the energy consumption that resource is refined, thus
Mitigate eco-environmental impact and destruction.
As global photovoltaic plant installation amount is continuously increased, the recycling after photovoltaic module is retired also becomes major issue.It loses
The cohesive force of EVA is predominant intermolecular forces in the crystalline silicon photovoltaic module of effect, how to destroy the active force and realizes component major part
Separation is the key problem of recycling.The cohesive force of EVA is predominant intermolecular forces in the crystalline silicon photovoltaic module of failure, according to different destructions
Main recovery technology route can be divided into following big classification by the method for cohesive force:
The first kind is physical method, mainly separates and recovers component using the method that physics is crushed, and broken material needs
Carry out further sifting sort.Main technical process is to carry out physics after being removed the component of recycling frame processing to break
Broken is particle, by sieving to particle, sorts after short grained mixture is further processed or directly sorts, more
It is sieved using electrostatic.As the English benefit of PV CYCLE and the country all use or studied such method.The advantages of such method, is:
Without using chemical solvent, chemical gas is not also generated, the feature of environmental protection is good；Operation is simpler, is easy to be mass produced；Recovery efficiency compared with
It is high.
Second class is pyrolysismethod, mainly using high temperature the EVA for playing cementation in component is reacted away, due to
EVA thermal weight loss in the case where 500 DEG C can achieve 100%, so EVA can be removed all under 500 DEG C of pyroreaction,
To destroy each main component that its viscosity splitting opens component.The main processes of this method are will to recycle component to tear open
The heat treatment that 500 DEG C or more are directly carried out after frame processing, the separation of each component is carried out to the component after heating, this method has can
It can obtain complete component.The companies such as German solar world and Deutsche solar AG all use such method.It is such
The advantages of method, is: being likely to be obtained whole parts and directly utilizes；Chemical substance yield is less；The recycling purity of material and return
Yield is higher.
Third class is solvent method, and this method is dissolved or is swollen to EVA using solvent, makes itself and component other parts
Separation, to obtain the various pieces of component.The first solar company in the U.S. proposes more mature photovoltaic module recycling stream
Journey, core are to be separated by solid-liquid separation component particle using reaction kettle, and metal and silicon materials are dissolved, high molecular material and glass
Glass is precipitated as insoluble matter.The component that T.Brnton of Belgian BP Solar company etc. forms 36 cell pieces of no backboard
It is immersed in 25h in 60 DEG C of nitric acid, has been successfully separated EVA, glass plate and cell piece.The method is removed just for EVA, and molten
The pernicious gases such as nitrogen oxides can be generated in solution preocess.The colleges and universities such as Japan and Korea S and research institution also use the method to be tested.This
The advantages of class method is: available whole parts directly utilize；Method is easily achieved.
There are also heating wire patterning method in addition to above method, EVA layer is cut using electric-heating-wire-heating, in addition there are also with
Upper several method carries out the process of Collaborative experiment, for example pyrolysismethod is in conjunction with solvent method, and physical method is in conjunction with pyrolysismethod etc..
Existing several crystal silicon component recovery technologies have respective problems and disadvantages:
Physical recovering method crystal silicon component is although easy to operate, but the disadvantages of this method is also very outstanding, physical method time
It is higher to receive the energy consumption needed；The component that need to be crushed is more, increases the cost and process of recycling；Since the whole mixture that carries out is broken
It is broken, and comparison glued between component each section is close, each material purity of separation is impacted, and recycling has certain difficulty.
Pyrolysismethod recycles crystal silicon component due to all decomposing EVA, and the energy consumption of this method recycling is higher, and includes numerous objects
Physicochemical reaction process has an impact to high purity substance acquirement, is needed in the high temperature process by whole organic matter pyroreactions
Fall, a large amount of pernicious gases can be generated and endanger environment.
Solvent method recycling crystal silicon component can obtain more complete component, and a kind of method being easily achieved, but should
The reaction time of method is generally longer, and recovery efficiency is low, and can generate a large amount of waste gas and waste liquid and generate very big harm to environment,
It is a kind of method for being not suitable for practical scale and using.
Heating wire patterning method is since heating wire is very thin, and size of components is bigger, and the alignment and heating wire when cutting are cut
It can guarantee that effectively cutting all is obvious problem existing for this method when cutting by larger resistance from EVA.
The above recovery method all exists from operation complexity, the purity etc. of influence and material recovery to environment
Certain drawbacks.
