Description
Technical Field
The invention belongs to the field of recovery processing of waste crystalline silicon solar cell modules, and particularly relates to an automatic disassembly recovery production line and method for waste crystalline silicon solar cell modules.
Background
With the development of society, crystalline silicon solar cell modules will be in high-speed development in the next decades. The recycling problem of the crystalline silicon solar cell module is solved while the crystalline silicon solar cell module is applied on a large scale.
Fig. 32 is a process exploded view of a crystalline silicon solar cell module. The crystalline silicon solar cell module is composed of a crystalline silicon cell stack 112, tempered glass 114, a high transparent EVA film 113 (ethylene-vinyl acetate copolymer), a general EVA film 111, a TPT back plate 110 (polyvinyl fluoride composite film), long and short aluminum frames H, G, a junction box 118, and the like. In the packaging process of the crystalline silicon solar cell module, the tempered glass 114 is used as a carrier of the crystalline silicon cell module 112. First, a first layer of highly transparent EVA film 113 is laid on the embossed surface of the tempered glass 114, the sunlight surface (front surface) of the crystalline silicon battery 112 is laid toward the first layer of highly transparent EVA film 113, a second layer of EVA film 111 is laid on the back surface of the crystalline silicon battery 112, and the TPT back plate 110 is laid on the second layer of common EVA film 111, thus forming a laminated assembly 115. Then, after lamination by a laminator, the EVA films 111, 113 are melt-bonded and adhesively cured to form a laminated battery assembly 116. The cured EVA films 111, 113 can fuse the TPT back-plate 110 and the crystalline silicon cell stack 112 into a whole, so that the crystalline silicon cell stack 112 is transmitted on the sunlight surface of the tempered glass 114. Finally, silica gel is injected into the sealing grooves of the long and short aluminum frames H, G, and the packed battery assembly 117 is formed through riveting or interference connection of the respective corner codes of the four corners.
Junction boxes 118 are mounted on the TPT back plane surfaces of the individual crystalline silicon solar cell modules for interconnecting solar energy with external power modules to output power of the solar energy system to the outside. The bus tape connected to the battery sheet is extended to the outside through the process port reserved in the TPT back plate 110. Depending on the actual mounting location, silicone is applied to the mounting surfaces of the TPT back plate 110 and the junction box 118. The terminal block is tightly mounted on the TPT back plate 110. Then, one end of the bus bar is connected with the anode and the cathode of the solar energy system, and the other end is connected with the circuit board in a screw fixing manner, so that the bus bar is fixed on the junction box 118. And finally, the box cover is buckled on the junction box.
At present, china has no major breakthrough in the field of disassembly and recovery of crystalline silicon solar cell assemblies, and has no mature and perfect disassembly process and recovery equipment. At present, equipment and methods for disassembling and recycling crystalline silicon solar cell modules at home and abroad are rare. The recycling problem of crystalline silicon solar cell modules is to be solved in order to realize the principle of harmless, recycling and reduction of wastes. The recovery and harmless treatment of crystalline silicon solar cell modules become a very important concern in the industry and environmental community in the world in the future.
