Abstract
The invention discloses a no-damage recycling method for a photovoltaic module. The method comprises the following steps that (1) the photovoltaic module is placed on a flat operation platform with the glass face facing downwards; and (2) under the condition that the photovoltaic module or a steel wire or a blade is heated, glass and packaging materials are separated, and a separated upper layer is lifted up during separation, or the glass and the packaging materials are separated directly without heating through the steel wire or the thin blade which rotates at a high speed. By means of the method, the technical problems that in an existing photovoltaic module recycling technique, the recycling rate is low, the energy consumption is high, and secondary pollution occurs are solved. By means of the method, the glass and the packaging materials can be separated rapidly, the number of working procedures is small, and operation is easy; energy consumption is low; meanwhile, the later operation for separating the packaging materials and battery pieces is facilitated.
Description
Technical field
The present invention relates to a kind of method that photovoltaic module reclaims cycling and reutilization, particularly relate to a kind of not damaged recovery method of photovoltaic module, be applicable to carry out harmless recovery to the photovoltaic module encapsulated by face glass; Belong to solar photovoltaic assembly recovery and utilization technology field.
Background technology
Solar energy industry is as a kind of low-carbon (LC), reproducible clean energy resource, and development in recent years is rapid.While bringing clean energy resource, the recycling technology of effective waste and old photovoltaic module seems more and more important and urgent.The valuable resources such as the silicon in photovoltaic module, silver, copper, aluminium, major part can both realize cycling and reutilization by recovery, can economize on resources, and reduces and to exploit Resources and to reduce the power consumption that resource refines, thus alleviate eco-environmental impact and destruction.Therefore, the recovery of photovoltaic module and harmless treatment are the problems that current international and domestic industrial circle and environment circle are extremely paid close attention to.Can say how effectively photovoltaic module to be recycled, just become a ring important in theCourse of PV Industry strategy.
Existing photovoltaic module recovery technology, generally carries out recovery by heat treatment and chemically treated method to photovoltaic module.As product high temperature incineration or fluidized-bed reactor heat treatment realize being separated of glass and encapsulating material, but energy consumption is higher, and the gas of generation also can cause secondary pollution to environment.
Chemical treatment generally uses inorganic or organic acid to dissolve, and realizes being separated of glass and encapsulating material.But because encapsulating material is wrapped between glass, dissolve needs about 7 days, the cycle is longer, and the post processing of a large amount of solvent is also problem.
Also having a kind of is use the method pulverized to be pulverized by assembly, is then separated the material of mixing.But this method is difficult to the abundant separation realizing one-component, not only length consuming time and glass are totally disrupted, and organic efficiency is low.
Also have the method that product heat treatment combines with chemical treatment in addition, first use high temperature that assembly is separated automatically with glass, then cell piece is isolated in the process of product solvent.But the heat treated time is longer, energy consumption is large, and energy consumption remains a problem.
Summary of the invention
The present invention is directed to the technical problems such as the rate of recovery existed in existing photovoltaic module recovery and utilization technology is low, energy consumption is high, secondary pollution, a kind of not damaged recovery method of photovoltaic module is provided, improve organic efficiency, reduce energy consumption.
For this reason, the present invention adopts following technical scheme:
A not damaged recovery method for photovoltaic module, comprises the steps:
(1) photovoltaic component glass is faced down, be placed on smooth operating platform;
(2) under the condition heating photovoltaic module or steel wire or blade, glass is separated with encapsulating material; And in the process be separated, the upper strata after being separated is mentioned; Or, utilizing the steel wire of high-speed rotation or thin blade, directly glass being separated with encapsulating material when not heating.
Further, in above-mentioned steps (2), use steel wire or the blade of band heating function, be heated to 110 ~ 130 degrees Celsius, glass is separated with encapsulating material; And in the process be separated, the upper strata after being separated is mentioned.
Further, described steel wire or blade are heated to 120 degrees Celsius.
Further, in above-mentioned steps (2), photovoltaic module is heated to 140 ~ 160 degrees Celsius in advance in laminating machine, insulation 25 ~ 30min, is separated with encapsulating material glass; And in the process be separated, the upper strata after being separated is mentioned.
Further, described photovoltaic module is preheated to 150 degrees Celsius.
In the not damaged recovery method of photovoltaic module of the present invention, not only achieve the quick separating of glass and encapsulating material, and because steel wire does not contact glass with thin blade, to glass nondestructive wound, destroy, can directly use after glass cleaning, operation is few, simple to operate; Less energy consumption, more environmental protection; In addition, to follow-up encapsulating material and cell piece be separated provide convenient.
