Description
Technical field
The invention belongs to solid waste resource recovery process field, particularly relate to a kind of system processing Waste ammunition
And method.
Background technology
Along with science and technology high speed development, during waste electric products and electronic product machining formed leftover pieces also with day
All increasings.The 1% of municipal refuse is accounted for respectively in developed country such as Japan, the U.S., European Union's electronic waste annual production, 2-5% and 4%,
And with the speed increment of every 5 years 16%-28%, it is 3-5 times of municipal refuse growth rate.This situation is the tightest in China
Weight, China is the most populous, simultaneously or developed country dumps the main place of electronic waste, the data display U.S. 80%
Electronic waste exports to Asia, wherein 90% enters China.
The technology recycled about useless circuit board both at home and abroad mainly include mechanical separation method, hydrometallurgical technology,
Biological metallurgy technology and pyrolytic technique, these technology heat extraction relieving the exterior syndrome major parts all pay close attention to the gold reclaimed in waste printed circuit board
Belong to.The wherein easy scale of mechanical separation method, and the pollution to environment is relatively small, but various metal cannot be completely separated,
Residual organic substances or landfill or burning, not only waste resource and also environmental pollution is serious；The metal recovery rate of hydrometallurgy
Height, but chemical reagent consumption is relatively big, and complex process, the macromolecular organic compound in wiring board is also without being recycled profit
With；Biological metallurgy technology is at present also in conceptual phase, and applicable antibacterial is considerably less and very difficult cultivation；Comparatively speaking, logical
Cross the combination of pyrolytic technique pyrolytic and physical separation method, can not only metal in efficient recovery Waste ammunition can also
Utilize macromolecule organic material therein, be broken down into fuel oil, combustion gas and carbide, simultaneously because the non-gold in electronic product
Belonging to and mostly be the high molecule plastics such as epoxy resin, the carbide phosphorus content of pyrolysis product is high, is suitable as industrial chemicals and uses.
