Pond recovery technology field.
Background technology
With society, economic fast development, the demand to the energy is increasing, and the energy turns into restriction countries in the world in short term
The key factor of economic development, increasing country starts to develop solar energy resources, seeks the new power of economic development.The sun
Can be both primary energy, be again regenerative resource.Its aboundresources, both can freely use, and without transporting, in use
To environment without any pollution, most cleaning and the environment-friendly energy are generally considered.In past more than 20 years, solar-electricity
Installation of the pond in various countries constantly increases in geometry level.EPIA (EPIA)] prediction, the year two thousand twenty photovoltaic generation can
The installed capacity of 345GW is provided, the installed capacity of 1081GW can be provided to the year two thousand thirty.
Although solar energy is considered as a kind of minimum energy of waste yield, during the use of solar module not
Can produce environmentally harmful waste, but the solid waste produced after solar cell is scrapped can not be ignored.At this stage, it is brilliant
Body silicon solar cell accounts for whole photovoltaic market share about 80%, and in leading position, and general crystal silicon solar batteries make
It is 25-30 with the life-span, after service life, the transformation efficiency of solar cell can drastically decline, until failing, scrapping.
In recent years, the solar panel that the nineties in last century installs subsequently enters disenabling stage.How effectively to reclaim and process into
Enter disenabling stage crystal silicon solar energy battery turn into ensure crystal silicon solar energy battery industry sustainable development it is important because
Element.

Master switch is closed after being cooled to room temperature, component is taken out, glass is to be completely segregated.
Further, in step s 2, the component after disassembling is positioned in high-pressure hydrothermal reaction kettle, adds reaction medium
To not having component, speed of agitator is set to 58-65rpm, closes heater switch after 20-35h is reacted under 190-250 degrees Celsius, extremely
Master switch is closed after being cooled to room temperature, component is taken out, glass is to be completely segregated.
The present invention carries out solvent heat or hydro-thermal on the basis of manually terminal box and aluminium frame is disassembled to remaining component
Treatment carries out the initial gross separation of component, and glass is separated with the remainder of component, be next step cell piece complete separation with
Material further with provide basis.Classification recovery is carried out by the various types of materials in the component that gives up, resource has both been saved, and
Reduce the discharge capacity of discarded object.
