Description
Technical field
The present invention relates to one and disassemble process equipment, disassemble process equipment particularly to a kind of Environment-friendlycircuit circuit board, belong to waste and old electric electric equipment products and disassemble process environmental protection industry (epi).
Background technology
Printed substrate is the important component part in electric equipment products, along with the continuous renewal of electronic product is regenerated, the abandoned printed circuit board having at least few hundred thousand tonnes of every year produces, discarded 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 discarded circuit board, deal with improperly and environment will be caused serious secondary pollution.Therefore, how to be effectively realized the innoxious recovery of discarded 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 defect of prior art and deficiency:
The Technology of abandoned printed circuit board 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 discarded 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 television circuit board, 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.The fractionation of existing discarded television circuit board also has three kinds of modes, one is chemical method, chemical liquid is used to dissolve so as to separate by the bump that wiring board connects with components and parts, the method production efficiency is low, dissolve after the metals resources response rate low, and the method also needs to use substantial amounts of clear water to clean medicinal liquid remaining on material, substantial amounts of acid pickle can be produced and acid waste gas affects environment；Another kind disassembles mode for heating sealing-off, utilize the low-melting feature of scolding tin, the bump fusing connected with components and parts by wiring board makes components and parts separate, the method can efficiently separate components and parts and can reclaim scolding tin but production capacity is relatively low, and lead fume and release harmful gas can be generated in case of heating due to the lead in scolding tin and the fire retardant in wiring board, institute is in like fashion to environment, personal injury is bigger；The third mode is that machinery splits, and the method is only applicable to the wiring board without the bigger components and parts such as high voltage package, fin, but all contains these bigger components and parts on the wiring board after detachment of worn-out electrical appliances.
