Description
Technical Field
The utility model belongs to the technical field of recycling treatment, and particularly relates to a recycling device for waste solar modules.
Background
Nowadays, the new device quantity of the global solar module is greatly grown in 2010, and China is actively pushing green energy conversion and non-nuclear home to generate solar energy, which is one of the main forces of renewable energy at present. Under normal use, the service life of the solar photoelectric module can reach more than 20 years, so that solar power generation is one of important targets in alternative energy sources which can be continuously developed in the nature, and therefore, the solar photoelectric module is not promoted in all countries of the world, and when the global solar photoelectric new device quantity is greatly grown, a large number of waste solar modules can be expected to be generated in the near future, and the problem of waste disposal of huge solar modules is likely to be faced in the future. The existing technology for disposing the waste solar modules is not suitable for disposal, but only can be disposed in a buried manner, which not only results in high disposal cost and environmental burden, but also provides effective solutions and technical countermeasures if the waste solar modules can be disposed in advance for recycling, thereby not only creating recycling economic benefits, but also reducing environmental burden, and the solar module recycling industry can be operated and developed together with the solar industry for a long time when the recycling cost is lower and the selling price of the recycling resources is higher.
The existing solar module mainly comprises a solar cell, a glass cover plate and a plastic backboard which are arranged on two sides of the solar cell, and a metal outer frame (generally an aluminum frame) which surrounds the solar cell, the glass cover plate and the plastic backboard; the glass cover plate and the plastic back plate are combined with the solar cell by an encapsulating material (vinyl acetate polymer (Ethylene vinyl acetate, EVA) to form a complete solar module, wherein the encapsulating material EVA is a material for tightly adhering the glass cover plate, the solar cell and the plastic back plate together, and the encapsulating material EVA has good weather resistance, so that the service life of the solar module can be prolonged to 20 years, and the encapsulating material EVA is a material which is difficult to process when the solar module is recycled and decomposed.
In the existing recovery method of the waste solar module, the metal outer frame is usually removed through mechanical disassembly, and the solar cell and valuable metal are still tightly covered by the glass cover plate, the EVA and the plastic back plate, so that the recovery materials such as glass, solar cell wafers and metals can be obtained through detailed decomposition. The main recovery mode at present is as follows:
the crushing method is to crush the module (glass cover plate/EVA/solar cell/EVA/plastic back plate) directly in the modes of roller, hammer, centrifugal wind, etc., then screen the crushed part according to different particle sizes, and finally select according to color or density, the color can be selected according to transparency to separate glass and metal, and the density can be selected according to size to separate inorganic matters (glass, metal, silicon, etc.) and organic matters (EVA, back plate, etc.). The recovery processing classification device of solar panel of taiwan patent No. M633283 includes a crushing mechanism and an eddy current screening mechanism which are connected with each other, wherein the recovery solar panel is mainly placed in a feed hopper groove of the crushing mechanism, and is guided to a rotary cutter shaft below the feed hopper groove by a material guiding rotary drum to be crushed to form crushed aggregates, and then is conveyed to the eddy current screening mechanism by a material guiding conveying frame, and is conveyed and moved by a conveying belt, so that when the crushed aggregates pass above an eddy current roller on the inner side of the conveying belt, the crushed aggregates are classified into metal substances and nonmetal substances by eddy current capability excited by the eddy current roller and then are ejected out, and are directly dropped into a corresponding metal collecting unit and nonmetal collecting unit by gravity, and are output by a metal material output device and a nonmetal material output device respectively to be classified and collected; thus, the recovery process classification of recovered solar panels (2022, 10, 21 patent bulletin data reference) was achieved. The equipment investment of the crushing method is less, but EVA is still attached to the glass cover plate and the solar cell after treatment, so the selling price of the recycled resource is lower.
The solution method is mainly to grind the glass cover plate and the plastic backboard, then the residual part (EVA/solar cell/EVA) is dissolved or the viscosity of the EVA is reduced (usually dissolved) by the solution method, the solvent is selected from acid, alkali, organic solvent and the like, and after the EVA is removed, the cell can be collected. Taiwan patent No. I798067, "grinding type solar module recovery apparatus", includes: a platform having a solar module placement area; the grinding cutter is arranged above the platform and moves relative to the solar module placement area; and a negative pressure collector comprising a negative pressure suction head and arranged above the platform for collecting grinding powder under negative pressure; wherein the grinding tool and the negative pressure suction head are fixed in the same shell (2023, 04, 01, patent publication reference). Taiwan patent No. I798636, "solar cell module recovery and planing device", is suitable for planing a solar cell module, and the solar cell module recovery and planing device comprises: a platform for carrying the solar cell module; the device comprises at least one planing device, a planing member and a cover shell, wherein the planing member is arranged on the platform and can be contacted with a backboard of the solar cell module, the cover shell covers the planing member, and defines a planing space and is provided with an air inlet and an air extraction opening which are communicated with the planing space; the transmission device is connected with the at least one planing device and can drive the at least one planing device to move so as to enable the planing piece to plane the solar cell module, and enable external air to enter from the air inlet and contact with the planing piece, and the planing material generated in the planing space can be pumped out of the planing space through the air inlet and the pumping hole through the matching of the air inlet and the pumping hole; and a measuring device, including an optical ruler and a measuring piece, the optical ruler is set in the transmission device to measure the relative position of the planing pieces, the measuring piece is set in the opposite side of the platform to the solar cell module to measure the thickness of a cover plate of the solar cell module (2023, 04, 11 patent bulletin data reference). However, the solution method has a major problem in that the EVA is treated with a chemical solution, and after the treatment of the module, a more procedure is required to treat the waste solution, and although the waste solution can be recovered and reused by filtration, centrifugation, distillation, etc., the additional time or energy will increase the treatment cost.
The heat treatment method comprises the steps that before the heat treatment method is carried out, the metal outer frame is removed, and then the backboard of the solar photoelectric module is removed, wherein most backboard is composed of fluorine-containing polymers at present, and substances which are harmful to organisms and environment can be generated in the heat treatment process of the fluorine-containing polymers; and removing the rest part (glass/EVA/solar cell/EVA) of the backboard, putting the backboard into a heat treatment furnace to thermally decompose EVA, and collecting glass and a cell piece respectively after EVA is decomposed. The heat treatment method is to crack or burn EVA in the solar photoelectric module by using heat energy, however, organic waste gas, acid gas or dioxin and the like may be generated after the EVA is thermally decomposed, and metal components in the solar photoelectric module may be discharged due to high temperature, so that subsequent tail gas needs to be carefully treated. Taiwan patent No. I783429, a solar photovoltaic module plasma thermal cracking recovery device, includes: the vacuum chamber is used for carrying out an inductively coupled plasma anaerobic thermal cracking reaction, is arranged on a first box body, and is provided with a first end and a second end which are corresponding to each other, the first end is provided with a chamber door, the bottom end of the chamber door is connected with a sliding rail, the sliding rail is arranged on a second box body and can be used for the side reciprocating sliding of the vacuum chamber to open or close the chamber door, the chamber door is provided with a carrying platform, at least one material to be treated is arranged on the carrying platform, and the material to be treated can be automatically conveyed and carried into the vacuum chamber, wherein the material to be treated is a waste or decommissioned solar photoelectric module (photovoltaic module) after an aluminum frame and a junction box are removed; an automatic control module, which is arranged in the second box body and comprises a programmable logic controller (Programmable Logic Controller, PLC) and a control interface unit, wherein the programmable logic controller is used for a user to switch the automatic control module into an automatic operation mode or a manual operation mode, and the control interface unit is provided with a fool-proof mechanism for real-time abnormality and emergency stop, so that misoperation is prevented and safety protection is realized during the whole operation period; the vacuum cavity is provided with a vacuum valve, a cavity vacuum gauge, a process vacuum gauge, a pressure regulating valve and an air suction control electromagnetic valve, wherein an air inlet control electromagnetic valve is arranged between the vacuum cavity and the cavity vacuum gauge; and an inductively coupled plasma module comprising an induction coil surrounding the vacuum chamber and an RF plasma power generator disposed in the first chamber and coupled to the induction coil through an auto-match controller to drive the induction coil to generate inductively coupled plasma (inductively coupled plasma, ICP), wherein the inductively coupled plasma is utilized to concentrate a high energy heat source into the abandoned or decommissioned solar photovoltaic module by an oxygen-free thermal cracking reaction, and silicon, metal, glass and carbon are primarily layered after cracking packaging materials and plastic back plates of the abandoned or decommissioned solar photovoltaic module, wherein the packaging materials are vinyl acetate polymers (Ethylene vinyl acetate, EVA) (2022, 11-day patent publication data reference). However, the metal outer frame is disassembled first, and then the waste solar modules are recycled by a heat treatment method, which adds a treatment procedure, so that the waste solar modules cannot be recycled continuously and rapidly for reuse. The foregoing lack of the existing recycling technology for waste solar modules is a major problem to be overcome in the industry.
