Description
Technical field
The invention belongs to resource recovery device field, particularly relate to a kind of discarded printed circuit boards and disassemble process device.
Background technology
Printed circuit board (PCB) is the important component part in electric equipment products, along with the continuous renewal of electronic product is regenerated, the discarded printed circuit boards having at least few hundred thousand tonnes of every year produces, waste printed circuit board is mainly made up of organic fortified resin, glass fibre, Copper Foil and electronic component, wherein contain substantial amounts of valuable metal (such as copper, ferrum, aluminum, stannum etc.), possibly together with noble metal (such as Au Ag Pt Pd etc.), there is significantly high resource reclaim and be worth. But, possibly together with poisonous and harmful substances such as the various heavy such as lead, hydrargyrum, cadmium, chromium and halogenide fire retardants in waste printed circuit board, deal with improperly and environment will be caused serious secondary pollution. Therefore, how to be effectively realized the innoxious recovery of waste printed circuit board, it is achieved its renewable resources, for alleviating ambient pressure and preventing the pollution of the environment, improve the reuse ratio of secondary resource, it is ensured that China's economy, society and environment sustainable development suffer from highly important meaning.
The Technology of discarded printed circuit boards recycling of recyclable waste both at home and abroad mainly has chemical method, heat treating process and mechanical approach at present. 1, chemical method is to utilize acid solution by the dissolving metal in waste printed circuit board, then it is reduced respectively. The method can produce substantial amounts of waste water and sour gas, and operational danger is high, and needs the more fund of input to complete the improvement of follow-up three industrial wastes, and produced economic worth substantially reduces, and easily causes secondary pollution if dealing with improperly; 2, heat treating process includes incineration method, cracking process, and the method easily causes the effusion of toxic gas, and the noble metal in electron wastes also easily volatilizees with muriatic form, decreases the direct recovery rate of metal, and the waste gas after burning is serious to atmospheric effect; 3, Mechanical Method is the crumbling method of current more employing, it is divided into Integral-crushing and splits broken, owing to comprising multiple components and parts on TV set circuit plate, for instance high voltage package, fin, capacitor etc., these components and parts have plenty of solid or the simple metal parts that resin is filled, it is bigger that Integral-crushing realizes difficulty, equipment energy consumption is big, also can produce substantial amounts of heat while broken, and broken rear various metals mixes complicated component, sorting difficulty strengthens, and reduces the recovery value of resource; And adopt and first split mode broken again, it is possible to first split by electron wastes, classification is reclaimed, classifying crushing, reduces equipment energy consumption, improves resource reclaim and is worth.
