Description
Technical field
The present invention relates to environmentally friendly recovery technology fields, scrap photovoltaic module disassembling method more particularly to one kind.
Background technique
China is the production of photovoltaic module and applies big country, and only China's production photovoltaic module in 2017 is more than 60GW, according to
7.6 ten thousand tons/GW is converted, only photovoltaic module in 2017, and after it is scrapped, gross mass will surpass 4,560,000 tons.
Most of material of photovoltaic module is the material of recyclable reconstruction, recycles to photovoltaic module and realizes cycling and reutilization,
It can economize on resources, the energy consumption that Resources are exploited and reduced with resource refinement be reduced, to mitigate eco-environmental impact and destruction.
The composition of photovoltaic module is glass 70% (weight accounting, similarly hereinafter), aluminium frame 18%, silicon material 4%, noble metal
0.15%, terminal box 0.85%, backboard 1%, EVA 6%.
When recycling waste and old photovoltaic module, needs to split component, aluminium frame, glass and junction box part are gone
It removes, obtains silicon wafer.Effectively completed silicon wafer recovery method has " inorganic acid solution method " and " heat treating process ".Wherein, the latter
It is divided into " fixed container heat treating process " and " fluidized-bed reactor heat treating process " again.
1) inorganic acid solution method
EVA is dissolved after a period of time in a certain temperature conditions with nitric acid and hyponitric acid mixed acid, with
Glass classification.This method can keep the complete of crystal silicon chip, but need further to handle silicon wafer.
2) fixed container heat treating process
Photovoltaic module is put into incinerator, 600 DEG C of reaction temperature of setting is burned.After the completion of burning, by battery, glass
Glass and frame etc. separate by hand.The various types of materials of recycling enters corresponding reclaimer, and the material of Plastic burns completely.
3) fluidized-bed reactor heat treating process
Discarded photovoltaic module is heat-treated using fluidized-bed reactor.Fine sand is put into fluidized-bed reactor,
Under certain temperature, the air effect of flow velocity, fine sand is in boiling hot flow regime, the physical property with liquid.Component is put into
In fluidized bed, EVA and back veneer material can gasify in the reactor, and exhaust gas then enters secondary combustion chamber from reactor, as anti-
Answer the heat source of device.Reach 400 microns or more of cell piece for thickness, intact silicon wafer can be recycled.Not due to manufacturing technology
Disconnected development, for cell piece by for thinning, heat treating process can not obtain intact silicon wafer, therefore also be merely able to be suitable for recycling silicon
Material.
In addition to above-mentioned 3 kinds of methods, there are also " organic acid-soluble method " and " physical partition methods "；
4) organic acid-soluble method
It is swollen EVA with organic solvent, to achieve the purpose that split cell piece, EVA, glass and backboard.The time required to the method
Longer, about 7 days are the primary first-order equation period.In addition, keep cell piece broken after EVA expansion and there are problems that organic liquid waste processing,
Therefore the method is still in the laboratory research stage.
5) physical partition method
First component aluminum frame and terminal box are removed, then crush rimless component, separates tin-coated welding strip and glass particle, is remained
Under part ground again, obtain metal, Si powder, backboard particle and EVA particle with electrostatic separating method.The method is final to be obtained
To the mixture for being different materials, it is not able to achieve being sufficiently separated for one-component, still in the laboratory research stage.
From the point of view of having the technical method for scrapping photovoltaic module and experience both at home and abroad:
Inorganic acid and organic acid dissolution: just for the removal and separation of EVA, not again in view of the dismounting of frame and silicon wafer
It utilizes.And needing to use a large amount of chemical reagent, remaining waste liquid also belongs to danger wastes.This method was both uneconomical, also not
Environmental protection.
Heat treating process: disposal process can generate a large amount of organic exhaust gas, and this method was both uneconomical, also not environmentally.
Physical partition method: it is incomplete, fail to separate each single component.
Therefore, the method for seeking a kind of demolishing and scrapping photovoltaic module of environment friendly and economical, can be improved the rate of recovery, and tear open
Breakage rate is reduced in solution preocess, meets country's expectation index, it appears very necessary.
