Embodiment Construction

[0012] Cleaning and equipment requirements:

[0013] 1) To corrode the aluminum layer of thin fragments of solar cells or IC fragments (hereinafter referred to as fragments), the equipment is made of imported high-quality PP materials, the thickness of the tank body is made of 10mm stainless steel, and the surface layer is treated with "Teflon" method. A sealing cover is added to the upper part of the tank to prevent gas from distributing. The PP pipe is used as the blowing pipe, and the air source is three-stage clean compressed air. The PP pipe is introduced into the liquid tank for surfing and bubbling, and the viscosity of the debris when it meets water is completely separated, and the distribution is in a sheet shape, and both sides reach the condition of being corroded.

[0014] 2), corrode the debris silver layer, the equipment and conditions used are the same as 1).

[0015] 3) Corrosion debris heavy metal ion layer, the equipment and conditions used are the same as 1...

Abstract

The invention is a method for recycling the solar battery thin fragment or IC fragment, relating to waste regeneration field. The design proposal of the invention is that part of the expensive metal of the fragment has yet not been extracted. The prior art is conducted by a certain production technology and cleaning working procedure. The key point of the invention is that the compositions of the working procedure is used for cleaning and chemical corroding the aluminum layer face of the solar battery thin fragment or the IC fragment and the silver main fence line and the silver accessory fence line; eliminating the heavy metal ion of the oxidation horizon, which comprises the silver, aluminum and silicon alloy of the surface layer of the oxidation horizon; the fragment is cleaned by a cleaning device in the air-blowing surfing rolling type acid-bases soaker; the residue of the fragment is further cleaned out by a stainless steel basket in running water; and then the fragment is dehydrated and dried. The cleaning working procedure comprises the steps as follow; yellow water rolling type surfing immersion cleaning; hydrofluoric acid rolling type surfing immersion cleaning; acid-bases rolling type surfing immersion cleaning; pure water supersonic wave cleaning; pure water dip rinse cleaning; dehydrating and drying; and vacuum packing. The invention has the advantages of extracting and utilizing mostly expensive metal of the fragment and creating wealth for the society.

Description

technical field [0001] The invention relates to the field of waste regeneration, and relates to a method for recycling thin battery fragments or IC fragments. Background technique [0002] At present, although the method of battery recovery is published. For example, application number 200510100209.6 discloses a method for one-step extraction and separation of nickel, magnesium, and cobalt from sulfuric acid solution recovered from nickel-hydrogen and nickel-cadmium batteries. But the method of recycling thin solar cell fragments or IC fragments has not been reported yet, because a considerable part of the precious metals in these fragments has not been extracted and utilized, and it is a pity to treat them as waste. And so far, people have not yet obtained the technology and method of recycling. Contents of the invention [0003] The present invention aims at the above-mentioned existing problems, and aims to provide a method for recycling thin solar cell fragments or I...
