Description
Technical field
The present invention relates to technical field of waste treatment more particularly to kinds of processes apply to electronic waste it is pollution-free processing with
The method of resource utilization.
Background technique
It is Chinese to scrap more than 5,000,000 television sets, 4,000,000 refrigerators, 5,000,000 computers and 60,000,000 hands every year
Machine, the electronic waste generated every year is more than 2,300,000 tons, and is increased year by year, and the electronic waste by illegal channels import is more than
14000000 tons.Therefore, electronic waste to be treated reaches 16,300,000 tons or more every year in China.It is opened from January 1st, 2011 in China
" waste electric appliance and electronic Product recycling handles management rules " the regulation waste electrical and electronic equipment for beginning to implement recycles operator couple
The waste electric products of recycling are handled, and waste electrical and electronic equipment processing qualification should be obtained.Even but having obtained
Waste electrical and electronic equipment handles the enterprise of qualification, and treatment process still continues to use traditional " baked wheaten cake ", and (burning-off plastics leave gold
Belong to, generate a large amount of exhaust gas and residue) and " washing " (use strong acid or " chloroazotic acid " to dissolve metal, the plastics through acid soak are discarded into
For new rubbish), resource utilization rate is low, a large amount of waste water,waste gas and industrial residue is generated in treatment process, to air, river,
It is lauched, soil etc. causes serious pollution.Therefore, there is an urgent need to one kind not to produce secondary pollution, can be to waste electronic in China
The processing method of the recyclings such as plastics, copper, aluminium, iron in product.
Summary of the invention
The present invention in view of the above problems, propose a kind of completely new pollution-free processing of electronic waste for not generating secondary pollution with
The method of resource utilization.One side treatment process does not generate the pollution such as waste water,waste gas and industrial residue；On the other hand by electronic waste
In plastics, copper, aluminium, iron all recycle, recycle, so that electronic waste is become resource, the harm by electronic waste to environment
It is preferably minimized.
The technical scheme is that the following steps are included:
1) method manually dismantled takes out the device of the noxious material contained in electronic waste, separately deals with；
2) remainder is put into crusher and is crushed；
3) broken mixture is divided into iron, copper aluminium mixture, plastics three parts, wherein iron enters iron charge collector, modeling
Material enters non-metal collection device；
4) copper aluminium mixture enters grinding glomeration copper, alumina particles mixture in grinder；
5) spherical copper, alumina particles mixture are sorted at copper, aluminium, and then, copper enters copper collector, aluminium enters aluminium collection
Device；
6) it completes.
2, the method for a kind of electronic waste according to claim 1 pollution-free processing and resource utilization, feature
Be, step 2,3), 4), 5) in generate dusty gas through pipeline be collected into deduster processing it is up to standard after discharge.
In the way of the mechanical treatment of the full physics such as broken, separation, grinding, sorting, dedusting, treatment process does not produce the present invention
Raw secondary pollution；By electronic waste automatic sorting, at plastics, iron, copper, aluminium, (device of the noxious material contained in electronic waste is such as
Kinescope, fluorescent screen etc. manually take out, and separately deal with) and all recycle, so that discarded electronic waste is become resources circulation
It utilizes, not only electronic waste is preferably minimized the pollution of environment, also saves vast resources.In operating cost, although equipment
The certain operating cost of the generations such as depreciation, power consumption, but electronic waste treated plastics, iron, copper, aluminium can be used as associated row
The raw material of industry generates certain economic benefit, in addition the subsidies granted for policy considerations that country handles electronic waste, with the technology of the present invention
Processing electronic waste can generate preferable economic benefit, and at current price measuring and calculating processing electronic waste can produce 500-1300
Yuan/ton economic benefit (related with electronic waste type).In addition, the technology of the present invention and conditional electronic garbage treating process phase
Than treatment effeciency format high throughput is big, the economic benefits generated every year.Therefore, the technology of the present invention is electronic waste processing row
A kind of revolutionary processing method of industry, has important economy, social effect to China environmental protection, comprehensive utilization of resources.
