[0002] Photovoltaic modules, the primary source of photovoltaic power, typically have a service life of 20 to 30 years. They are expected to see a large-scale retirement in the future. PV modules contain a large number of recyclable materials, such as aluminum alloy frames, copper cables, glass panels, silicon cells, copper solder ribbons, and silver electrodes, and possess significant economic and resource value.

[0003] However, since the glass plates of photovoltaic modules are usually tightly bonded to the battery adhesive layer, related technologies usually require that the glass plates and the battery adhesive layer be completely broken before separation, resulting in very low efficiency in removing the glass plates of photovoltaic modules and the inability to recycle silicon cells with intact battery adhesive layers.

[0030] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] It should be noted that the terms "including" and "having" in the embodiments of the present application and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0032] It will be understood that the terms "first", "second", etc. used in this application may be used to describe various elements in this document, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

[0033] In related technologies, the steps of recycling photovoltaic modules include: cutting off the cables of the photovoltaic modules, scraping off the junction boxes of the photovoltaic modules, removing the aluminum frames of the photovoltaic modules, obtaining photovoltaic laminates, removing the fluorine-containing backsheet of the photovoltaic laminates, removing the glass sheets, pyrolysis to remove the adhesive film in the battery adhesive layer, and wet purification to obtain silicon of a certain purity and a silver-containing solution.

[0034] Among them, glass plate removal is one of the most critical steps in the recycling of photovoltaic modules, including the following three reasons: 1. The mass of glass plates in photovoltaic modules accounts for about 70%, which is the part with the highest mass proportion in photovoltaic modules; 2. Due to the similar material properties of glass and silicon, the mixing of glass impurities in silicon makes silicon difficult to separate and purify, thereby reducing the value of the recycled products. Therefore, glass plate removal is a prerequisite for recycling silicon cells, and the removal rate of glass plates greatly affects the recycling purity of silicon cells; 3. For the removal of broken glass plates, related technologies usually require multiple crushing and multi-pass screening, and the required equipment and processes are relatively complex.

[0035] For intact, unbroken glass sheets, the hot knife method is typically used. This involves heating the photovoltaic laminate to soften the adhesive film of the cell adhesive layer. The heated knife is then used to separate the intact glass sheet from the cell adhesive layer. While the hot knife method can remove and recycle glass sheets, it is not suitable for broken or uneven glass sheets.

[0036] Based on this, roller extrusion, which is suitable for broken or uneven glass sheets, has gradually been adopted. In this method, the photovoltaic laminate is crushed by a pair of rollers with a specific shape, which initially separates some of the broken glass. The remaining glass in the cell adhesive layer is then crushed and screened to further remove the broken glass. Although this method can separate the broken glass sheets, it is relatively complex and does not produce intact silicon cells.

[0037] In view of this, an embodiment of the present application discloses a recycling device for photovoltaic modules. By providing a recycling shell, a transmission mechanism, and an injection mechanism, the transmission mechanism can transport photovoltaic modules with the glass plate facing upward, that is, the glass plate can be directed toward the injection mechanism. The injection mechanism includes an injection head. The spray particles ejected by the injection head can exert an impact force on the glass plate, causing it to break into glass particles, thereby reducing the adhesion between the glass plate and the battery adhesive layer until the glass particles and the battery adhesive layer fall off. The recycling device of the present application can not only achieve efficient separation of the glass plate and the battery adhesive layer, but also recycle complete silicon cells.

[0038] The following is a detailed description with reference to the accompanying drawings.

[0039] like Figure 1 As shown, Figure 1 The figure is a schematic diagram of a photovoltaic module disclosed in the related art, wherein photovoltaic module 100 may refer to a photovoltaic module after preliminary processing, i.e., a photovoltaic laminate. A photovoltaic laminate may refer to a semi-finished photovoltaic module made by bonding two or more layers of the same or different materials, after cell packaging but before the installation of a junction box, lead wires, and frame. The preliminary processing in this application may include steps such as cutting the photovoltaic module's cables, removing the photovoltaic module's junction box, and removing the photovoltaic module's aluminum frame.

[0040] The photovoltaic module 100 may include a glass plate 101 and a battery adhesive layer 103 encapsulating a silicon battery 102. The battery adhesive layer 103 may be composed of the silicon battery 102 and an adhesive film. The adhesive film has a certain degree of viscosity, which can make the glass plate 101 adhere to the battery adhesive layer 103. Figure 1 The bottom layer of the photovoltaic module 110 may be a backsheet.

[0041] Optionally, the glass plate 101 may be a complete glass plate or a broken glass plate. In the case where the glass plate 101 is a broken glass plate, the glass plate 101 may include multiple glass fragments, each of which adheres to the battery adhesive layer 103, which increases the difficulty of removing the glass plate 101.

[0042] like Figure 2 As shown, Figure 22 is a schematic diagram of a recycling device for photovoltaic components disclosed in an embodiment of the present application. The recycling device may include a recycling shell 210, a transmission mechanism 220 and an injection mechanism 230.

[0043] The recovery shell 210 has a recovery space formed therein, and the recovery shell 210 is provided with a feed port and a discharge port connected to the recovery space.

[0044] The transmission mechanism 220 is arranged in the recycling space, and one end of the transmission mechanism 220 is arranged corresponding to the feed port to receive the photovoltaic components. The photovoltaic components are configured to be located on the transmission mechanism 220 with the glass plate facing upward, and the other end of the transmission mechanism 220 is arranged corresponding to the discharge port.

[0045] The injection mechanism 230 is arranged in the recycling space. The injection mechanism 230 includes an injection head. The injection head is located in the recycling space and is arranged toward the transmission mechanism 220. The injection head is configured to spray spray particles toward the photovoltaic components on the transmission mechanism 220, so that the glass plates on the photovoltaic components are broken into glass particles and separated from the battery glue layer of the photovoltaic components. The discharge port is configured to discharge the separated battery glue layer.

[0046] The recycling device disclosed in the present application is configured to provide a spray mechanism with a spray head on a recycling shell, and utilize the spray head to spray the photovoltaic module positioned on a transmission mechanism with the glass plate facing upward. The spray particles sprayed by the spray head can exert an impact force on the glass plate, causing it to break into glass particles, thereby reducing the adhesion between the glass plate and the battery adhesive layer until the glass particles and the battery adhesive layer fall off. The recycling device for photovoltaic modules of the present application can, on the one hand, achieve efficient separation of the glass plate and the battery adhesive layer, thereby improving the recycling efficiency of the photovoltaic modules. On the other hand, the recycling device of the present application can separate the glass plate and the battery adhesive layer by shattering the glass plate. Compared with the method in the related art that requires both the glass plate and the battery adhesive layer to be broken to achieve separation, it can recycle complete silicon cells, further improving the recycling rate of the components of the photovoltaic modules.

[0047] In addition, the recycling device of the present application is not only applicable to the case where the glass plate on the photovoltaic module is a complete glass plate, but is also applicable to the case where the glass plate on the photovoltaic module is broken or damaged, thereby helping to expand the scope of application of the recycling device.

[0048] Optionally, the recycling shell 210 can be made of metal or composite materials, which is not limited to this. For example, the recycling shell can be a stainless steel shell, or it can also be a plastic shell.

[0049] The recycling space formed inside the recycling shell 210 can be closed, with only a feed port and a discharge port, so as to prevent the spray particles sprayed by the injection mechanism 230 and the broken glass particles from splashing, which not only protects the staff and the surrounding environment, but also facilitates the collection and recycling of the spray particles and glass particles.

[0050] Optionally, the transmission mechanism 220 may include a transmission member and a driving member. The transmission member may be made of a flexible material, such as a rubber track, and the driving member may include a motor. Figure 2 As shown, the conveyor mechanism 220 can be located within the recycling space of the recycling housing 210. One end of the conveyor can pass through the inlet of the recycling housing 210 to connect with the photovoltaic modules 100 to be processed, which are transported by the loading mechanism outside the recycling housing 210. The other end of the conveyor can be located at the outlet of the recycling housing 210 to discharge the separated battery adhesive layer. Optionally, both ends of the conveyor can be located within or outside the recycling space, without limitation.

[0051] During the transmission process of the photovoltaic module 100, the battery glue layer side of the photovoltaic module 100 can face the transmission mechanism, and the glass plate side can face the injection mechanism 230, that is, the photovoltaic module 100 is transmitted with the glass plate facing up and the battery glue layer facing down, so that the spray particles injected by the injection mechanism can impact the glass plate of the photovoltaic module 100, so that the glass plate is broken into glass particles separated from the battery glue layer, and the broken glass particles can fall into the recycling space.

[0052] Optionally, the adhesive film in the battery adhesive layer can be made of EVA (Ethylene-Vinyl Acetate), which can cushion the spray particles sprayed onto the photovoltaic module 100 by the spray mechanism 230, preventing the impact from damaging the silicon cells encapsulated in the battery adhesive layer. In addition, because the transmission member is made of a flexible material, it can also provide a certain degree of cushioning.

[0053] Specifically, the photovoltaic component 100 that has undergone preliminary processing enters the transmission mechanism 220 in the recycling space through the feed port. The transmission mechanism 220 is started. Driven by the driving member, the transmission member can transmit the photovoltaic component 100, and the photovoltaic component 100 will be impacted by the spraying particles during the transmission process, so that the photovoltaic component 100 removes the glass plate during the transmission process, and then discharges the separated battery glue layer from the discharge port.

[0054] It can be understood that the impact range of the spray particles sprayed by the spray mechanism 230 can be located in the middle area of ​​the recovery space, so that the glass plate is impacted in the middle area of ​​the recovery space, which can better prevent the spray particles and broken glass particles from splashing out of the recovery space.

[0055] Optionally, the transport mechanism 220 can be located below the spray mechanism 230, thereby increasing the impact force through gravity and reducing the energy consumption of the spray mechanism. During the transport process, when the photovoltaic module 100 reaches the impact area of ​​the spray mechanism 230, the spray mechanism 230 can be activated and the spray head can spray the spray particles to impact the glass plate of the photovoltaic module 100.

[0056] Optionally, the spraying mechanism 230 may spray the spray particles by squeezing and spraying with compressed air, squeezing and spraying with high-pressure water, accelerating and ejecting with a rotating impeller, etc., which are not limited to the above and are merely examples.

[0057] Optionally, the material of the spraying particles may include stainless steel, diamond, glass, etc., which is not limited thereto. Optionally, the shape of the spraying particles may include spherical, blocky, etc., which is not limited thereto.

[0058] In one embodiment, the spraying mechanism 230 further includes a main body component, and a spray head is rotatably mounted on the main body component so that the spraying angle of the spray head relative to the conveying mechanism 220 is adjustable; and / or the spray head is movably mounted on the main body component so that the spray head can be moved in a direction perpendicular to or parallel to the conveying direction of the conveying mechanism 220. By adjusting the spraying angle of the spray head and / or the manner in which the spray head is moved, the impact range of the sprayed particles can be changed. The impact range can be a circular area, a sector area, or a strip area, so that the impact range of the sprayed particles can cover the entire glass plate of the photovoltaic module.

[0059] For example, the transporting direction of the transport mechanism 220 may be horizontal, and the spray head may move in a vertical direction or a horizontal direction.

[0060] In one embodiment, the spray mechanism 230 may also include multiple spray heads, which may be spaced apart on the main body. The multiple spray heads are configured to simultaneously spray material particles toward different positions of the conveying mechanism 220, thereby breaking the glass sheet into glass particles and separating them from the silicon cells. It will be appreciated that the coordinated spraying of the multiple spray heads can improve the efficiency and effect of the impact on the glass sheet.

[0061] In one embodiment, the recycling device further comprises a recycling box, which is arranged in the recycling space and is located below the spray head. The recycling box is configured to recycle the spray particles and the glass particles. Figure 3 As shown, Figure 3This is a schematic diagram of another recycling device for photovoltaic modules disclosed in an embodiment of the present application. The recycling device may also include a recycling box 240. The recycling box 240 and the injection mechanism 230 may be respectively located on both sides of the transmission mechanism 220 along the thickness direction, so that the spray particles ejected by the injection mechanism 230 and the glass particles separated from the battery glue layer after impact fall into the recycling box 240, thereby realizing the collection and recycling of the spray particles and glass particles.

[0062] The recovery box 240 can be located below the conveying mechanism 220, and the spraying mechanism 230 can be located above the conveying mechanism 220. The recovery box 240 is at least partially disposed in correspondence with the conveying mechanism 220, i.e., the recovery box 240 is at least partially located directly below the conveying mechanism 220. The recovery box 240 can cover the impact range of the sprayed particles and is larger than the impact range, thereby preventing the sprayed particles and glass particles from splashing and scattering in the recovery space.

[0063] It is understood that the spraying material particles and glass particles in the recovery box need to be separated, and the separation method can be determined according to the size and / or material of the spraying material particles and the size of the glass particles.

[0064] As an optional embodiment, the recovery box 240 may further include a partition. The partition is configured to form a first space and a second space arranged along the height of the recovery box 240. The first space is used to recover spray particles, and the second space is used to recover glass particles. Optionally, the first space can be located above or below the second space, without limitation.

[0065] Optionally, the spacer may be a screen, and the particle size of the glass particles may be different from the particle size of the spray particles, and the particle size may refer to the particle diameter.

[0066] As an example, Figure 4 As shown, Figure 4 FIG2 is a schematic diagram of another photovoltaic module recycling device disclosed in an embodiment of the present application. The recycling device may further include a separator 250, which may be disposed in a recycling box 240 to separate the spraying particles from the glass particles. The first space of the recycling box 240 may refer to the space above the separator 250 in the recycling box 240, and the second space of the recycling box 240 may refer to the space below the separator 250 in the recycling box 240.

[0067] For the spray particles collected in the first space, Figure 4In the embodiment, the recovery device may further include a spray recovery pipe 260, which is used to recover the spray particles to the injection mechanism 230. The feed port of the spray recovery pipe 260 may be connected to the recovery box. Specifically, the feed port of the spray recovery pipe 260 may be connected to the first space of the recovery box 240, and the discharge port of the spray recovery pipe 260 may be connected to the injection mechanism 230. The separated spray particles can be transported back to the injection mechanism 230 through the spray recovery pipe 260 to achieve reuse of the spray particles.

[0068] For the spraying particles collected in the second space, a drawer-shaped or bucket-shaped collecting member can be provided in the second space for easy collection and cleaning, and the collecting member can be emptied and replaced regularly.

[0069] Optionally, the recovery box 240 may not be provided with the separator 250. In this case, the feed port of the spray recovery pipe 260 is still connected to the recovery box 240, but the discharge port of the spray recovery pipe 260 can be connected to the separation mechanism, and the separator is then provided in the separation mechanism. The mixture containing the spray particles and the glass particles can be transported to the separation mechanism through the spray recovery pipe 260, and then separated from the glass particles by the separator of the separation mechanism.

[0070] Optionally, the glass particles have a smaller size than the spray particles, and the separator is provided with a plurality of sieve holes, the size of which is smaller than the size of the spray particles and larger than the size of the glass particles. Therefore, glass particles with a smaller size than the sieve holes can pass through the separator 250, while spray particles with a larger size than the sieve holes cannot pass through the separator 250, thereby allowing the spray particles to remain in the first space and the glass particles to fall into the second space.

[0071] It should be understood that the particle size of the broken glass particles is usually within a certain range. As long as the spraying particles with a particle size exceeding this range are used in advance and the isolation member 250 with a sieve size also exceeding this range is used, the separation function of the isolation member can be achieved.

[0072] As another optional embodiment, the spray particles may be magnetic particles, and the recovery box 240 may be provided with a magnetic member configured to attract the spray particles to separate the spray particles from the glass particles. As an example, the spray particles may be stainless steel balls, and the isolation member may be a magnet block, a magnet plate, or a magnet holder. The magnet can attract the stainless steel balls through magnetic force, while the glass particles are not affected by the magnet's magnetic force, thereby achieving separation between the two.

[0073] In addition, in order to more clearly illustrate the feeding and discharging process of the recycling device, as shown in the following figure: Figure 5 As shown, Figure 5FIG2 is a schematic diagram of another photovoltaic module recycling device disclosed in an embodiment of the present application. The recycling device may further include a loading mechanism 270 and a battery adhesive layer collection box 280. The loading mechanism 270 may be located at the feed port of the conveying mechanism 220, and the battery adhesive layer collection box 280 may be located at the discharge port of the conveying mechanism 220.

[0074] The loading mechanism may include a roller transmission member, one end of which can be connected to photovoltaic recycling equipment in other recycling processes, and the other end can be connected to the recycling device of the present application. The battery glue layer collection box 280 can collect one or more separated battery glue layers discharged from the discharge port.

[0075] In order to more clearly express the effects brought about by the present application, as shown in Table 1, Table 1 is a comparison table of the present application and the related art using the hot knife method and the roller squeezing method to remove the glass plate.

[0078] As can be seen from Table 1, the method disclosed in this application is smaller in size, consumes less power, has a faster processing speed, is compatible with various glass sheets, has a higher removal rate for broken glass sheets, and can obtain intact silicon cells. It should be understood that in the process of removing glass sheets from photovoltaic modules, the cooperation of multiple devices is required, such as Figure 5 As shown, the recycling device is composed of a loading mechanism, a battery glue layer collection box and equipment contained in a recycling shell. The above-mentioned equipment size may refer to the size of the equipment that performs the glass plate removal process, such as the size of the equipment contained in the recycling shell.
