Description
Technical field
The invention belongs to photovoltaic material field.
Background technology
Along with developing rapidly of solaode industry, the total output of solar components also fast lifting, but, along with too
The increase of sun energy battery service life, inferred, in the near future according to the service life of solar photovoltaic assembly, it will
There is substantial amounts of photovoltaic module to scrap, and in the production process of solar components, also have defective products and occur.Therefore, too
The problem that sun energy assembly reclaims has been put on agenda.
Would generally use the metal such as silicon or indium, gallium, cadmium, titanium in flexible solar assembly, have is expensive, has
Such as unreasonable recovery after assembly is scrapped, then can bring greatly pollution to environment.But, flexible solar assembly is multilamellar
Compound structure, due to solar components to weather-proof, block water, the requirement of the performance such as fire-retardant, its header board comprised, backboard
And packaging adhesive film layer is respectively provided with the character of indissoluble and infusibility, this makes to allow them separate with chip and becomes extremely difficult, from
And cause the raw-material recovery problem being positioned on chip costliness to become thorny.
From the point of view of at present, the recycling of flexible solar assembly mainly has two kinds of methods, and one is calcination method, the highest warm forging
Burn whole photovoltaic module, remaining non-combustible part is recycled；Another method is to be pulverized by flexible unit
After, use soda acid to soak assembly fragment, utilize the etching action of acid & alkali liquid that the coating material on chip is dissolved into acid & alkali liquid
In reclaim.Both approaches not only inefficiency, energy consumption is high, and if the header board of flexible unit is fluorine-containing, after burning
Hydrogen fluoride gas, serious environment pollution can be produced.Therefore, the recovery of flexible solar assembly is the most urgently to be resolved hurrily one
An individual difficult problem.
Summary of the invention
It is an object of the invention to provide a kind of easy and simple to handle, integrated cost is low, organic efficiency is high, eco-friendly flexibility too
Sun can assembly recovery method.
For achieving the above object, the present invention is by the following technical solutions:
The recovery method of a kind of flexible solar assembly, comprises the steps:
1) cryogenic separation: flexible solar assembly to be recycled is placed in deep freeze refrigeration plant 2～60 minutes, by institute after taking-up
The chip stating flexible solar assembly separates with other each layer；
2) coating material separate: the coating material on described chip is separated, obtain containing coating material wait be enriched with
Material and backing material；
3) coating material enrichment: the described coating material treated in enrichment material is carried out enriching and recovering, obtains coating raw material.
Optionally, in described step 1) in, the low-temperature receiver of described deep freeze refrigeration plant can be liquid oxygen or liquid nitrogen.
Optionally, in described step 2) in, the method for acidleach can be used to be carried out by the coating material on described chip
Separate.
Optionally, in described step 2), it would however also be possible to employ the coating material on described chip is carried out point by the method for sandblasting
From.
Further, the method for described sandblasting can be the method for dry type spraying sand or wet blast.
Optionally, the abrasive material used in the method for described sandblasting is quartz sand, corundum, emergy, copper ore or sea
One or more in sand.
Optionally, described sandblasting is carried out in the environment of 2～6 atmospheric pressure.
Optionally, described flexible solar assembly to be recycled is flexible copper indium gallium selenide solar components, flexible amorphous silicon
Solar components, flexible cadmium telluride solar components, flexible GaAs solar components or flexible dye-sensitized solar group
Part.
Optionally, the substrate of described flexible solar assembly to be recycled is rustless steel.
The present invention is by carrying out subzero treatment to flexible solar assembly so that be able between chip and other each layers effectively divide
From, thus ensure that subsequent recovery steps smooth, efficiently carry out, efficiently solve in prior art due to each layer of assembly
It is difficult to efficiently separate and can only assembly entirety be processed, then causes the difficulty of efficient recovery composition separating-purifying difficulty
Topic.Additionally, use liquid nitrogen or liquid oxygen low-temperature receiver to carry out subzero treatment, it is to avoid high temperature incineration mode produces harmful gas and causes
Environmental hazard.
The blasting method that the present invention uses can realize being physically separated of the coating to chip and backing material, effectively reduces
Type requirements to backing material, particularly with having for the flexible solar assembly at the bottom of stainless steel lining the most excellent
Gesture, because prior art generally using the method for acidleach dissolve the coating material at the bottom of stainless steel lining, but rustless steel
In the ferrum element that contains also can take advantage of the occasion to enter acid solution, and during other metal of subsequent extracted, the existence meeting of ferrum element
Recovery difficult is significantly increased, and the ferrum after reclaiming is worth the lowest, thus reduce what flexible solar assembly reclaimed
Economy.Coating material at the bottom of stainless steel lining can be separated, effectively by method effectively that use sandblasting with at the bottom of stainless steel lining
Control ferrum in rustless steel to enter in the coating material separated.
For Zong He, the recovery method of flexible solar assembly of the present invention has organic efficiency height, low cost, behaviour
Make simple advantage, have broad application prospects.
