Description
Technical field
This utility model relates to old circuit board recovery technology field, is specifically related to a kind of old circuit board cracker.
Background technology
Abandoned printed circuit board, as the significant components of electron wastes, had on the one hand both contained various heavy and the harmful substances such as lead, cadmium, igelite, brominated flame retardant, there is potential environmental pollution；On the other hand contain again the multiple common metal such as copper, gold, silver and rare precious metal, there is higher recycling and be worth.
Along with the enforcement of China's strategy of sustainable development, having higher requirement environmental conservation, the recovery of electronic waste becomes, with utilizing, the thorny problem that majority state faces.China has become the production and consumption big country of household electrical appliance at present, only to scrap renewal 2% calculating year, the annual 4 big class household electrical appliance eliminated just reach 20,000,000, the high-tech electronic products such as the computer of 2-4, mobile phone are only had plus the universal update cycle used in the whole society, and the novel household appliance product of the super quality and competitive price continued to bring out so that the renewal of scrapping in actual year of China's household electrical appliance is up to more than 25,000,000.Printed substrate (PCB) is as the critical component in discarded household electrical appliances, and it reclaims and resource problem becomes the hot issue being badly in need of solving.It addition, so far, Nei Diyou printed substrate manufacturing enterprise of China about 1000, PCB in China yield in 2006 is 129,640,000 m2, annual value of production 12800000000 dollars, have become as the big manufacturing country of PCB first, a large amount of leftover pieces in production process, the recovery scrapping plate also face great difficult problem.
Abandoned printed circuit board is the mixture of glass fiber reinforced plastics and various metals, belong to typical electron wastes, the old circuit board grown with each passing day is plus producing a large amount of leftover bits that wiring board produces, if not dealing carefully with and disposing, not only can cause a large amount of losses of useful resources, and environment can be produced serious harm.Tradition is stacked or the method for landfill, do not only take up a large amount of space, and contained heavy metal such as hydrargyrum, chromium, cadmium etc. and macromolecule organic are difficult to degraded under field conditions (factors), harmful components can pass through water, air, soil entrance environment, can cause potential, long-term and expendable harm to human health and ecological environment, lead contained therein is the second largest source of lead in municipal waste." old circuit board " is not " refuse ", but untapped " Secondary resource ", there is the highest recycling and be worth.Metal content in wiring board be equivalent to tens times of metal content in common mineral to hundreds of times, the content of metal is up to 40%, and most is copper, in addition with gold, aluminum, nickel, lead, silicon metal etc., is wherein no lack of rare metal；And rich ore tenor in nature super only 3%～5%.Having statistical data to show, 1t waste printed circuit board can extract the gold of about 300g.The material such as scolding tin on printed substrate and plastics, is also the valuable source that can be recycled.Therefore, research and development harmless treatment waste printed circuit board technology has become as the key subjects in regenerated resources field.
The wiring board scrapped is implemented effective process and resource recycling, can significantly slow down the consumption to Resources, alleviate environmental pollution, to setting up resource-conserving and environment-friendly society, develop a circular economy and there is positive effect and important meaning.
The main treatment technology of old circuit board at present: pyrometallurgy, hydrometallurgy, Physical.
Pyrometallurgy is extracted noble metal and is had simple, a convenient and response rate high, but produces harmful gas in burning process cause the shortcomings such as secondary pollution, other metal recovery rate is low, processing equipment is expensive owing to there is Organic substance；
Wet method control technology for gold be more common, from waste electric products, extract the technology of noble metal, wet method controls the ultimate principle of technology for gold can be dissolved in the feature of nitric acid and chloroazotic acid etc. mainly by noble metal, it is removed from waste electric products and is reclaimed from liquid phase.Compared with pyrogenic process, wet method controls that the waste gas of technology for gold discharge is relatively fewer, extract the residue after noble metal is also easy to process, but the waste liquid produced is more, and the complex treatment process of waste liquid, cost is the highest.Environment is caused certain potential threat
Physical treatment method mainly includes the multiple technologies such as Mechanical Crushing, elutriation and magnetic absorption.At present, physical treatment method is mainly used in the recovery of metal such as aluminum, copper, and as the U.S. utilizes strength rotational flow separator to reclaim aluminum from the PCB of PC, by controlling charging rate, the purity of gained aluminum concentrate is 85%, and the response rate is more than 90%；Sweden utilizes motorized pulleys electrostatic separator to reclaim copper, and by design and operation parameter optimization, the grade of gained copper concentrate is 93%～99%, and the response rate is up to 95%～99%.Metal that current domestic employing physical treatment method is mainly to separate in waste electric products and nonmetal.But above-mentioned physical method can only process the wiring board without components and parts.For band components and parts wiring board because of above it with various electronic devices and components, the method for the method handling components by molten stannum used at present, belong to manual operations, inefficiency, the molten stannum waste gas of generation, complex treatment process, processing cost is higher, and environment is produced the biggest potential threat.
