Description

Electrical member recovery device and recycling system of the solar cell module TECHNICAL FIELD

The present invention provides an electrical member recovery device for a solar cell module for recovering an electrical member containing a useful metal such as silver, for example, of a solar cell module, and glass and useful metals in a solar cell module equipped with the electrical member recovery device. It relates to a solar cell module recycling system for separating different materials including.

In general, for example, as shown in FIG. 11, the solar cell module M includes a solar cell 3 and a wiring material 4 between the glass substrate 1 and the back sheet 2. The electrical member 5 is retrofitted using a sealing material 6 such as EVA, and has a rectangular plate shape. The panel product S using this is constituted, for example, by surrounding the solar cell module M with a frame 7 such as aluminum. In addition, the panel product S that has not been used due to the end of the life of the solar cell module M is discarded, but recently recycled.

Conventionally, a recycling system of this type is known, for example, first proposed by the applicant of the present application and published in Japanese Unexamined Patent Application Publication No. 2016-203128 (Patent Document 1). This separates the wiring terminal box and cable from the panel product S in advance, and removes the frame 7 to obtain a solar cell module M. Then, the solar cell module (M) is sent between the pair of crushing rollers with the glass substrate (1) down, and the glass is crushed by holding the solar cell module (M) by the pair of crushing rollers. The processed object of crushed glass is sent between a roller and a pressing roller to scrape off glass shards installed on the downstream side, and scrape off the crushed glass shards by a scraping roller. Accordingly, at the same time as the glass is recovered, a sheet-like member including the electric member 5 and the sealing material 6 attached thereto is obtained. The sheet-like member is subjected to subsequent processing by grinding or the like.

By the way, the electric member 5 attached to the sheet-like member contains a useful metal, and in particular, the solar cell contains silver, and thus the electric member 5 attached to the back sheet to recycle this useful metal. I want to plan recovery. In this case, for example, it is conceivable that the back sheet to which the electrical member 5 is attached is immersed in a chemical solution such as an alkaline release agent solution to recover the electrical member 5 by specific gravity separation (e.g., Japanese patent See Unexamined Patent Publication No. 2014-104406 (Patent Document 2), etc.).

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2016-203128 [Patent Document 2] Japanese Patent Laid-Open Publication No. 2014-104406

However, in order to extract a single metal, it is inevitable to finally use chemical treatment or melting treatment using chemicals, but for the recovery of the electrical member 5 containing this metal, the use of a chemical solution makes the treatment complex and the recovery cost increases. There was a problem.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an electrical member recovery apparatus and a recycling system for a solar cell module in which electrical members can be mechanically simply and easily recovered.

In order to achieve such an object, the electrical member recovery apparatus of the solar cell module of the present invention is a solar cell module obtained by retrofitting an electrical member including a solar cell and a wiring material thereof between a glass substrate and a back sheet using a sealing material. As an electrical member recovery device for a solar cell module that recovers the electrical member, the electrical member is recovered as much as possible from a sheet-like member in a state in which almost all of the glass substrate has been removed from the solar cell module in advance and the electrical member is attached to the back sheet. In the solar cell module electrical member recovery device,

A supply unit that receives the sheet-shaped member and supplies the electric member downward, and the sheet-shaped member supplied from the supply unit is rotated by supporting the electric member downward and conveyed to the downstream side, and the sheet-shaped member And a brush roller for scraping off the electric member from the back sheet of, and a pressing means for relatively pressing the sheet-like member against the brush roller.

Even if some pieces of glass are attached to the supplied sheet-like member, there is no problem.

Therefore, when the sheet-shaped member is received in the supply unit and the electric member is supplied downward, the sheet-shaped member is supported by the brush roller and is conveyed by the brush roller while being pressed against the brush roller by the pressing means. The electric member attached to the sheet-like member is scraped off by the rotation of the roller. At this time, since the electric member is attached to the back sheet through the sealing material, the electric member is scraped off from the sheet-like member into fine powder pieces including the sealing material. In this case, it is ensured that the sheet-like member is pressed against the brush roller by the pressing plate and is scraped off. That is, the sheet-shaped member is conveyed by rotation of the brush roller, but since the pressing plate has sliding (slide) resistance, the sheet-shaped member is gradually conveyed and repeatedly rubbed by the brush roller. It is scraped off with fine powder pieces including the sealing material. Since the electrical member is scratched off, the electrical member can be easily separated mechanically from the sheet-like member without using a chemical solution, and the speed of recovery can be increased, and the recovery efficiency can be improved. The scraped off fine powder pieces are collected and these expensive useful metals such as silver can be extracted. The back sheet from which the electrical member has been scraped is discharged and, for example, incinerated. Further, in this case, among the electrical members, the solar cell is particularly fragile and easily scraped off, but wiring materials such as copper are thin and long, and thus some are entangled with the sealing material and remain on the back sheet. However, since expensive metals such as silver are mainly contained in solar cells, the recovery rate is high.

And, if necessary, a plurality of brush rollers are provided at intervals along the conveyance direction of the sheet-like member. By repeatedly scraping off the electric member by several brush rollers, the recovery rate of the electric member can be improved.

In addition, if necessary, the brush roller is installed on the base, the pressing means is replaced with the brush roller, and the sheet-shaped member slides into contact with the pressing plate, and the gap between the pressing plate and the brush roller is adjustable. It is configured with a support portion for supporting the pressing plate against the base. Thereby, the distance between the pressing plate and the brush roller can be adjusted by the support. Therefore, by adjusting the pressing force of the pressing plate, the conveying speed of the sheet-like member and the frequency of brush roller friction due to rotation of the brush roller can be appropriately adjusted, and scratching of the electric member can be reliably performed.

In addition, if necessary, a base member for holding the pressing plate at a lower side provided with the support part so as to move up and down with respect to the base, and the base member installed on the base are moved up and down while simultaneously moving the base member at a required vertical movement position. It is configured with a moving mechanism for positioning. Since a moving mechanism is installed, it is possible to easily adjust the gap between the pressing plate and the brush roller.

In this case, by using a jack having a worm wheel having a female screw for moving the male screw rod and the male screw rod forward and backward, and a gear case containing a worm for moving the male screw rod forward and backward by rotating the worm wheel, the jack A plurality of the base members are arranged at intervals along the width direction orthogonal to the conveying direction of the base member, and the gear case of the jack is installed on the base, while one end of the male jack rod is attached to the base member, and the base member It is effective to provide a gear transmission mechanism for transmitting the rotation of the electric motor to the worm shaft so as to rotate the electric motor and the worm shaft of the pair of jackworms in synchronization. Then, since a plurality of jacks were arranged at intervals along the width direction orthogonal to the conveying direction, the pressing force of the jack is strong, so that the pressing plate does not bend or shake during the scratching operation due to the rotation of the brush roller. The sheet-like member can be safely held, and thus the electric member can be reliably scraped off by the brush roller.

Further, in this case, it is effective to provide a position adjusting mechanism capable of adjusting the vertical position of the pressing plate with respect to the base member. Adjustment of the gap between the pressing plate and the brush roller can also be performed by a position adjusting mechanism. Therefore, the adjustment can be made delicately, so that the electric member can be reliably scraped off by the brush roller. The adjustment of the gap between the pressing plate and the brush roller is mainly performed as a moving mechanism.

Further, if necessary, a plurality of brush rollers are provided at intervals along the conveying direction of the sheet-like member, and the pressing plates are installed for each of the plurality of brush rollers, and the conveying direction of the sheet-shaped member of each of the pressing plates is upstream. The upstream side edge portion of the side is formed to be inclined upward toward the upstream side in the transmission direction. Since the pressing plate is installed independently for each brush roller, the pressing force against the sheet-shaped member is released once between the pressing plates, so that it is possible to prevent situations such as distorting due to the excessive force acting on the sheet-shaped member, while conveying smoothly. It can be scraped off by a brush roller. In addition, since the upstream side edge of each pressing plate is inclined upward, when the sheet-like member is conveyed, the tip edge is guided to reach the inclined upstream edge and advance toward the brush roller. It is possible to prevent the device from slipping out of the device and to reliably transfer the sheet-shaped member between the general portion of the pressing plate and the brush roller.

In addition, if necessary, a support plate for supporting the sheet-shaped member receiving the supply unit and a transfer roller rotating while contacting the sheet-shaped member on the support plate from above and sending the sheet-shaped member to the brush roller side while in contact with the support plate are provided. And composed. Since the sheet-shaped member is conveyed by the conveying roller, the sheet-shaped member can be reliably conveyed between the general portion of the pressing plate and the brush roller.

In addition, if necessary, a transfer conveyor for transferring the sheet-shaped member with its electric member down is installed on the upstream side of the support plate, and the loading surface of the sheet-like member of the transfer conveyor is lowered from the upstream side toward the downstream side. It has an inclined configuration. By conveying the sheet-like member at an angle, it is easy to load it on the support plate and at the same time, it is easy to be bitten by the conveying roller.

In this case, it is effective that a guide plate for guiding a sheet-shaped member installed facing the support plate is provided on the upstream side of the transfer roller, and the upstream side edge portion of the guide plate is formed inclined upward toward the upstream side. When the sheet-shaped member is conveyed from the conveying conveyor, the tip edge of the sheet-shaped member touches the inclined upstream edge of the guide plate and is guided to the guide plate, thus preventing the sheet-shaped member from being separated from the device by escaping upward. In addition, the sheet-like member can be reliably transferred toward the transfer roller.

And the recycling system of the solar cell module of the present invention for solving the above problems is useful in a solar cell module by retrofitting using an electrical member including a solar cell and a wiring material thereof between a glass substrate and a back sheet. In the solar cell module recycling system for separating other materials containing metal,

A solar cell module extraction device that removes the frame from the panel product in which the metal frame is installed on the solar cell module to take out and transmit the solar cell module;

The glass substrate of the solar cell module sent out from the solar cell module extraction device is shredded to remove almost all of the shreds including glass fragments and the glass substrate, and separated into a sheet-like member in a state in which an electric member is attached to the back sheet, and the sheet A glass substrate crushing and separating device that sends out a shape member, and

Intermediate particles (medium particles, neutral substances) including glass particles having a predetermined particle size range, and coarse particles having a size greater than or equal to the predetermined particle size range by using a frame to form a crushed material including glass pieces separated by the glass substrate crushing and separating device. A frame device for separating (coarse, 粗物) and fine particles (fine particles) having a size of a predetermined particle size or less, and

Wind sorting device for sorting glass particles by recovering lightweight powder by wind sorting from the intermediate particles separated by the glass fragment separation device,

A color classification device for separating and extracting colorless glass particles excluding colored glass particles as far as possible from the glass particles selected by the wind turbine sorting device, and

A metal removal device for removing metal from the colorless glass particles separated by the color separation device,

It has a configuration provided with an electric member recovery device of the solar cell module for recovering an electric member from a sheet-like member in a state in which the electric member is attached to the back sheet sent out from the glass substrate crushing and separating device.

As a result, the glass substrate shredding and separating apparatus removes almost all of the shreds including glass fragments and the glass substrate, and separates them into a sheet-like member with an electric member attached to the back sheet. In this glass substrate crushing and separating apparatus, since the electric member is also crushed to some extent, the crushed material includes fragments of the electric member.

Next, the crushed material is separated into an intermediate particle including glass particles having a predetermined particle size range by a frame device, coarse particles having a size larger than the predetermined particle size range, and fine particles having a size smaller than the predetermined particle size range. “Coarse particles” and “fine particles” are collected respectively.

Intermediate particles including glass particles having a predetermined particle size range are collected as glass particles by recovering lightweight powders from them by wind sorting by a wind sorting device. “Lightweight powder” is concentrated.

The sorted glass particles are removed from the colored glass particles as much as possible by a color classification device, and are separated and taken out as colorless glass particles. The "colored containing glass particles" are aggregated.

The colorless glass particles are purified by removing metal therefrom by a metal removal device. The “colorless glass particles” and the removed “metals” are collected respectively.

On the other hand, in the electrical member recovery device of a solar cell module, the electrical member attached to the sheet-like member is scraped off by rotation of the brush roller. At this time, since the electric member is attached to the back sheet through the sealing material, the electric member contains the sealing material and is scraped off with fine powder pieces from the sheet-like member. For this reason, it is possible to easily mechanically separate the electric member from the sheet-like member even without using a chemical solution, speeding up the recovery and improving the recovery efficiency. The back sheet is discharged with a lot of sealing material and a few electrical members attached, which are not scratched off. The scraped off “fine powder fragments including electrical elements” are collected.

Since the “fine powder fragments including the electric member”, “coarse particles”, “fine particles”, and “light powder” collected in this way contain useful metals such as silver, useful metals can be extracted from them.

In addition, the “metal” removed by the metal removal device includes relatively large copper used for wiring, etc., but metal can be extracted from now on. The back sheet is incinerated, for example, with a lot of sealing material and some electrical elements that are not scratched off.

And "colorless glass particles" from which the metal has been removed can be used as a raw material for various glass products. "Colored glass particles" can be used, for example, as civil engineering aggregates, rather than as glass products. In this way, the solar cell module can be effectively recycled in this system.

Further, if necessary, a back sheet shredding device is provided for shredding the sheet-like member from which the electrical member is recovered by the electrical member recovery device of the solar cell module. After that, for example, incineration treatment can be facilitated.

According to the present invention, in the electric member recovery apparatus, when the supply unit receives the sheet-shaped member and supplies the electric member downward, the sheet-shaped member is supported by the brush roller and is pressed against the brush roller by the pressing means while the brush roller Because the sheet-like member is gradually conveyed and rubbed repeatedly by the brush roller while being conveyed by the sheet-shaped member, the sheet-shaped member is scraped with fine powder pieces including the sealing material. Goes away Since the electrical member is scratched off, the electrical member can be easily separated mechanically from the sheet-like member even without using a chemical solution, so that the speed of recovery can be accelerated, and the recovery efficiency can be improved. The scraped off fine powder pieces are collected and expensive useful metals such as silver can be extracted from them.

In addition, the transfer roller 22 is rotated at the same time as it abuts on the top of the sheet-like member 8 on the support plate 21, and transfers the sheet-like member 8 to the downstream while slidably contacting the basic support plate 21. (8) can be transferred reliably.

The sheet-shaped member 8 conveyed by the conveying roller 22 of the feeding part 20 is supported by the brush roller 40 and applied to the brush roller 40 by the pressing means 50, as shown in FIG. 8. It is conveyed by the brush roller 40 while being pressed relatively, and the electric member 5 attached to the sheet-like member 8 is scraped off by the rotation of the brush roller 40 during this transfer process. At this time, since the electric member 5 is attached to the back sheet 2 through the sealing material 6, the electric member 5 including the sealing material 6 is formed into fine powder pieces from the sheet-shaped member 8. It scrapes away. In this case, the sheet-like member 8 is pressed against the brush roller 40 by the pressing plate 51 and is reliably scraped off. That is, the sheet-like member 8 is conveyed by the rotation of the brush roller 40, but since there is a sliding resistance of the pressing plate 51, the sheet-shaped member 8 is gradually conveyed by the brush roller 40. By repeatedly rubbing, the electrical member 5 contains the sealing material 6 from the sheet-like member 8 and is scraped off with fine powder pieces. For this reason, the electric member 5 can be easily separated mechanically from the sheet-like member 8 even without using a chemical solution, and the recovery speed can be increased, and the recovery efficiency can be improved. In this case, the solar cell 3 among the electrical members 5 is particularly fragile and easily scratched off, but the wiring material 4 such as a copper wire is thin and long, so it is wound around the sealing material 6 and placed on the back sheet 2. Some remain. However, since expensive metals such as silver are mainly contained in the solar cell 3, the recovery rate is increased.

Further, in this case, a plurality of brush rollers 40 (two in the embodiment) are provided at intervals along the conveying direction of the sheet-like member 8, so that the repeating electric member 5 is formed by the several brush rollers 40. By scraping off, the recovery rate of the electric member 5 can be improved.

In addition, the brush roller 40 is installed on the base 10 and is relatively pressed by the pressing plate 51 of the pressing means 50, but the pressing plate by the support 52 supporting the pressing plate 51 Since the distance between the 51 and the brush roller 40 can be adjusted, the pressure of the pressing plate 51 is adjusted to the conveying speed of the sheet-like member 8 and the brush roller 40 by rotation of the brush roller 40 It is possible to appropriately adjust the frequency of scraping, and it is possible to ensure that the electric member 5 is scraped off. The gap adjustment by this support 52 moves the base member 53 holding the pressing plate 51 up and down by the movement mechanism 54 and is positioned at the required up and down movement position, so the pressing plate 51 and the brush It is possible to easily adjust the distance between the rollers (40).

In addition, since there is a position adjustment mechanism 80 capable of adjusting the vertical position of the pressing plate 51 with respect to the base member 53, the adjustment of the distance between the pressing plate 51 and the brush roller 40 is performed by this position adjustment mechanism ( 80). Therefore, the adjustment can be made fine, and the electric member 5 can be reliably scraped off by the brush roller 40 by that amount. The adjustment of the distance between the pressing plate 51 and the brush roller 40 is mainly performed by the moving mechanism 54.

In this case, since the moving mechanism 54 is configured by disposing a plurality of jacks 60 at intervals along the width direction orthogonal to the conveying direction, the jack 60 has a strong pressing force, so it is scratched by the rotation of the brush roller 40. During the falling operation, the pressing plate 51 does not bend or shake, so that the sheet-like member 8 can be reliably held by the frictional resistance, so that the electric member 5 is scratched off by the brush roller 40. I can do it.

In addition, since the pressing plate 51 is installed for each of several brush rollers 40 and independently installed for each brush roller 40, the pressing force on the sheet-shaped member 8 between the pressing plates 51 is released once. Therefore, situations such as twisting due to an excessive force acting on the sheet-like member 8 can be prevented, and scraping by the brush roller 40 can be performed while conveying smoothly. In addition, since the upstream edge 51a of each pressing plate 51 on the upstream side in the conveyance direction of the sheet-like member 8 is formed inclined upward toward the upstream side in the conveyance direction, the sheet-like member 8 is conveyed. When the end edge is in contact with the inclined upstream edge portion 51a and guided to proceed toward the brush roller 40, the sheet-shaped member 8 escapes upward and prevents separation from the device. The sheet-like member 8 can be reliably transferred between the general portion of the pressure plate and the brush roller 40.

Next, a solar cell module recycling system R according to an embodiment of the present invention shown in FIGS. 1 to 3 will be described. In the recycling system R according to the embodiment, the frame body 7 and the solar cell module M are separated from the panel product S in which the metal frame body 7 is installed on the solar cell module M, and the solar cell module ( In M) it is to discriminate between glass and other materials including useful metals.

The basic configuration of this recycling system R is a solar cell module extraction device 100, a glass substrate crushing and separating device 110, a sieve device 120, a wind sorting device 130, a color sorting device 140, and metal removal. A device 150, the electric member collecting device K, and a back sheet crushing device 160 are provided.

The solar cell module extraction device 100 separates the frame 7 from the panel product S supplied from a stacker outside the city, and takes out the solar cell module M and sends it out. The solar cell module extraction device 100 is determined by a lifter 101 that moves the supplied panel product S to a predetermined position with the back sheet 2 of the solar cell module M upward, and the lifter 101. A panel conveying device 102 that adsorbs the back sheet 2 of the solar cell module M of the panel product S moved to the position by an adsorption board, and takes out the panel product S, conveys it to the required position, and determines the position. ), and a frame body separating mechanism outside the city that clamps and pulls the frame body 7 by hydraulic drive from the panel product S positioned at the required position. The panel conveyance device 102 conveys the solar cell module M from which the frame body 7 was separated to the glass substrate crushing and separating device 110. The “frame body (7)” is concentrated.

The glass substrate crushing and separating device 110 receives the solar cell module M conveyed by the panel conveyance device 102 from the solar cell module extraction device 100 from the delivery conveyor 111, and simultaneously loads the glass substrate 1 below. The glass substrate 1 of the solar cell module M delivered by the delivery conveyor 111 is crushed, and the crushed material including glass fragments and almost all of the glass substrate 1 are removed. It is separated into a sheet-like member 8 in a state in which the electric member 5 is attached to the back sheet 2 that has been formed, and the sheet-like member 8 is sent to the electric member collecting device K.

)를 행렬 형태로 설치하여 구성되어 있으며, 태양 전지 모듈(M)을 거의 수평 방향으로 반송하도록 설치되어 있다.As shown in Fig. 10, the glass substrate crushing and separating device 110 is inclined by the delivery conveyor 111 to hold the delivered solar battery module M, while transporting the rotated solar battery module M. A pair of crushing rollers 112 for crushing the glass substrate 1 of the battery module M are provided. Each of the pair of crushing rollers 112 has sharp crushed teeth on its outer circumferential surface (

) Is installed in a matrix form, and is installed to transport the solar cell module (M) in an almost horizontal direction.

In addition, in the glass substrate crushing and separating device 110, a roller 113 scraping off a piece of glass of glass attached to the back sheet 2 side of the solar cell module M installed on the downstream side of each crushing roller 10, and , It is equipped with a pressing roller 114 that presses the solar cell module (M) against the scraping roller (113). In addition, a plurality of sets (three sets in the embodiment) of the scraping roller 113 and the pressing roller 114 are arranged horizontally (sequentially installed, 列設). The scraping roller 113, like the crushing roller 112, is configured by installing sharp crushed teeth on its outer circumferential surface in a matrix shape, while the pressing roller 114 has its outer circumferential surface formed in a cylindrical plane, or It is formed similarly to the roller 112 and is rotatably supported. The shredded material including the shredded glass pieces is collected by the shooter 115 and transferred to the hopper 117 by the belt conveyor 116 and temporarily stored. On the other hand, a sheet-like member in a state in which almost all of the glass substrate 1 is removed from the solar cell module M by this glass substrate crushing and separating device 110 and the electric member 5 is attached to the back sheet 2 (8) is supplied to the supply unit 20 of the electric member collecting device K described above.

The sieve device 120 sieves the crushed material including glass fragments stored in the hopper 117 and supplied in an appropriate amount by a sieve, "intermediate particles" including glass particles having a predetermined particle size range, Coarse particles” and predetermined particles are also separated into “fine particles” having a size below the range. “Coarse particles” and “fine particles” are collected by putting them in containers or bags, respectively. The "intermediate particle" is conveyed to the next.

The wind sorting device 130 recovers lightweight powder from the "intermediate particulate matter" separated by the sieve device 120 by wind sorting, and selects and extracts "glass particles", and may adopt a known method. The “lightweight powder” is put in a container or bag to collect. The “glass particles” are then conveyed.

The color classification device 140 separates and removes colorless glass particles, excluding colored glass particles, as far as possible from the "glass particles" selected by the wind turbine sorting device 130. For example, when a glass particle is dropped and in this process, it is detected by an identification sensor such as a CCD camera to detect whether the glass particle contains a colored thing, and when it detects that it contains a colored thing, a small set of glass particles including the colored thing is created. For example, a known method of removing with an air ejector can be employed. The “colored-containing glass particles” are collected by being put in a container or bag. The “colorless glass particles” are then conveyed.

The metal removal device 150 removes metal from the “colorless glass particles” classified by the color classification device 140. For example, when the glass particles are conveyed by a conveyor, and the metal is detected by a metal detector in the conveying process, when the presence of metal is detected, a small set of glass particles including metal is removed, for example, by falling. A known method can be adopted. “Colorless glass particles” and “glass particles containing metals” are collected by being put in a container or bag.

The electrical member recovery device K is a sheet-like member in which almost all of the glass substrate 1 is removed by the glass substrate crushing and separating device 110 and the electrical member 5 is attached to the back sheet 2 ( Process 8). That is, as described above, in the electric member recovery device K of the solar cell module M, the electric member 5 attached to the sheet-like member 8 is scraped off by the rotation of the brush roller 40. At this time, since the electrical member 5 is attached to the back sheet 2 through the sealing material 6, the electrical member 5 including the sealing material 6 from the sheet-shaped member 8 is scraped as fine powder pieces. Goes away For this reason, the electric member 5 can be easily separated mechanically from the sheet-like member 8 even without using a chemical solution, and the speed of recovery can be increased, and the recovery efficiency can be improved. The back sheet 2 is discharged with a lot of sealing material 6 and some electrical members 5 attached, which are not scratched off. The scraped off "fine powder fragments including electrical elements" are collected. Details are as described above.

The back sheet crushing device 160 crushes the sheet-like member 8 from which the electrical member 5 has been recovered by the electrical member recovery device K of the solar cell module M. The “shredded material of sheet-shaped members” is put in a container or bag and collected.

In this way, the “fine powder fragments including electrical members”, “coarse particles”, “fine particles”, and “lightweight powders” that have been aggregated contain useful metals such as silver, and hence, expensive useful metals such as silver Can be extracted.

In addition, the "glass particles containing metal" removed by the metal removal device 150 is a metal, such as relatively large copper used for wiring or the like, but it is possible to extract metal from this as well.

The “shredding of sheet-like members” mainly includes a lot of sealing material 6 and some electrical members 5, which are not scratched off by the back sheet 2, but are disposed of by incineration, for example. It is also possible to have the electrical member take out.

And the “colorless glass particles” from which the metal has been removed can be used as a raw material for various glass products. The “colored-containing glass particles” can be used, for example, as a civil engineering aggregate, rather than as a glass product. In this way, in this system, the solar cell module M can be effectively recycled.

In addition, in the above embodiment, the electric member recovery device has been described as a device constituting the recycling system, but it is not necessarily limited thereto, and may be used alone, or even if appropriately changed, there is no problem. The present invention is not limited to the embodiments of the present invention described above, and those skilled in the art are easy to add many modifications to these exemplary embodiments without substantially departing from the novel teachings and effects of the present invention, and such many modifications It is included in the scope of.
