With while, the problem of will necessarily expiring in face of product up-gradation and life of product.In general environment, the design of photovoltaic module makes
With the service life at 25 years or so, and the upgrading of product can make the actual life of photovoltaic module be significantly shorter than its design use
Service life, a large amount of photovoltaic module can be eliminated because of performance failure or the updating and upgrading of a product.In the photovoltaic module being eliminated, packet
Contain numerous values and obtain recovery, with the material of recycling, such as glass and silicon etc..
Photovoltaic cell includes backboard, silicon cell, glass panel and EVA (second dilute-the dilute copolymer of acetic acid second) film.In photovoltaic
In the encapsulation process of component, one layer of EVA is laid between silicon cell and backboard, between silicon cell and glass panel respectively
Film makes EVA film generate melting gluing and glue connection solidification, the EVA film after solidification can be by silicon by carrying out the hot pressing of certain condition
Cell piece package gets up, and there are also glass panels with backboard, is integrated using vacuum lamination technology is glutinous, finally obtains photovoltaic cell.
It is integrated since the EVA film after solidifying firmly sticks backboard, silicon cell and glass panel, photovoltaic module is carried out
How the problem of recovery mainly separates the backboard, silicon cell and glass panel by EVA film gluing.
For the recycling and reusing problem of photovoltaic module, existing method generally passes through heat treatment and chemically treated method
Recovery is carried out to photovoltaic module.The photovoltaic module of failure first passes around manual type and removes its frame and terminal box, obtains
Photovoltaic cell；Then by heat treatment method, EVA film and backboard in photovoltaic cell are decomposed using high-temperature gasification；And then it is secondary
Welding, convergent belt and silicon cell are sorted by manual type；Finally, being carried out by chemical reagent to the silicon cell that sub-argument goes out
Processing, obtains silicon.This method can obtain the higher silicon of purity, but during managing at which, be heat-treated, thus
Energy consumption is higher, meanwhile, there is be easy to cause secondary pollution problems to environment in chemical treating process.
Summary of the invention
In view of the deficiencies of the prior art, the utility model devises a kind of nozzle, ejects the liquid with abrasive, makes
Each layer of photovoltaic back is successively separated.
