Description
Technical field：
The present invention relates to lithium ion battery recovery technology fields, and in particular to a kind of safe handling of electrification lithium ion battery
Method.
Background technology：
Since new-energy automobile develops rapidly, as high-volume power lithium-ion battery is scrapped, clean environment firendly has been badly in need of it
Mode handles waste battery.Currently, conventional treatment process includes pyrolysis and physical separation, it is required for the ability after overdischarge
Subsequent processing is carried out, old and useless battery regeneration cost is caused to greatly increase.
The present invention proposes a kind of safety and environmental protection processing method of electrification battery, and mistake by studying quick crashing condition
Realize that wastewater zero discharge, exhaust gas are properly disposed in journey.
Invention content：
Technical problem to be solved by the present invention lies in provide it is a kind of can effectively reduce regeneration cost, realize exhaust gas centralized
The security processing of the middle electrification lithium ion battery for collecting processing and wastewater zero discharge.
The technical problems to be solved by the invention are realized using technical solution below：
A kind of security processing of electrification lithium ion battery, including quick crashing, quickly break up, sub-pressure selective plastic partition
Film, eddy current separation shell, milling, proportion detach six processes, will charge shell fragment, the plastic diaphragms of lithium ion battery
Fragment, copper particle, alumina particles and battery powder are individually separated, the exhaust gas centralized collection processing generated in the process, and are realized useless
Water zero discharge.
The single shattering process of the electrification lithium ion battery must not exceed 0.5s, breaks up and falls directly into beater after being crushed
In, breaing up the time must not exceed 0.5s, and broken breakdown process total must not exceed 1s.
The sub-pressure selective requires air humidity to be maintained at 20% or less.To reduce the generation of hydrofluoric acid, slow down equipment
Corrosion.
The exhaust gas is through lye spray process, the direct biochemical treatment of waste water of generation, the reuse after matching alkali after filtering, production
Raw exhaust gas is handled by activated carbon adsorption desorption apparatus, desorption gas burning.
The security processing of above-mentioned electrification lithium ion battery is suitable for soft-package battery, square plastic housing battery, square aluminum
The regeneration of the waste and old lithium ion batteries such as housing battery, battery of mobile phone.
The sub-pressure selective realizes by winnowing machine and sorts that winnowing machine inner wall passes through preservative treatment, and powder applies used in anti-corrosion
Material is even by chlorinated polyether resin, anticorrosive packing, dicy-curing agent, acrylate polymer levelling agent, imidazoles accelerating agent, titanate esters
Connection agent is mixed.
The anticorrosive packing selects aerosil.
The chlorinated polyether resin, anticorrosive packing, dicy-curing agent, acrylate polymer levelling agent, imidazoles accelerating agent,
The mass ratio of titanate coupling agent is 45-65:15-30:5-10:0.5-2:0.1-1:0.1-1.
The anticorrosive packing is made by the modified processing of aerosil, and method of modifying is：First by gas phase titanium dioxide
Silicon is dried in 110~120 DEG C of baking ovens to constant weight, is added in absolute ethyl alcohol after temperature is down to 50 DEG C naturally, is dispersed with stirring
It is even, and it is heated to reflux state 10~30min of insulated and stirred, add isocyanuric acid three-glycidyl ester and hexamethylol trimerization
Cyanamide pregnancy ether, continues at 2~5h of insulated and stirred under reflux state, and gained mixture is dropped with the cooling rate of 5~10 DEG C/min
Then recycling ethyl alcohol is concentrated under reduced pressure to -10~-5 DEG C of insulated and stirred 0.5-1h in temperature, condensate residue is done in 70~80 DEG C of baking ovens
It is dry to constant weight, micro mist most is made through micronizer afterwards.
The mass ratio of the aerosil, isocyanuric acid three-glycidyl ester and hexamethylolmelamine pregnancy ether
For 20-30:5-10:5-10.
Using isocyanuric acid three-glycidyl ester and hexamethylolmelamine pregnancy ether as modifying agent, not only effectively improve
Its comixing compatibility between film-forming resin and function additive, and significantly increase the corrosion resistance of aerosil
Energy.
The operation principle of the present invention：
Waste and old lithium ion battery by quick crashing and is broken up, ensures to be crushed the time within 0.5s, is crushed and breaks up
Within 1s, then battery fragment would not burn, plastic diaphragms are sorted away followed by sub-pressure selective, then shell
Fragment is gone out by eddy current separation, and then the battery powder coating on pole piece is polished by flour mill, finally by than
It respectively is isolated by copper particle, the battery powder of alumina particles and black again；
Overall process takes negative pressure to operate, and exhaust gas then passes through work by removing a small amount of fluoride gas after lye spray
Property charcoal adsorption/desorption device, final combustion processing.The waste water that spray generates passes through biochemical treatment, and lye is added after filtering and is delivered to
Spray equipment recycles, and sediment merges sale with battery powder.
The beneficial effects of the invention are as follows：
(1) security processing of present invention electrification lithium ion battery, which needs not move through electric discharge, to carry out, and avoid routine
Pyrolysis and physical separation methods could carry out subsequent processing and cause old and useless battery regeneration cost big after having to pass through electric discharge
Big the problem of increasing；
(2) security processing of present invention electrification lithium ion battery not only realizes the centralized collection processing of exhaust gas, keeps away
Exempt from exhaust gas and arbitrarily discharges the post-processing operation for simplifying exhaust gas while causing environmental pollution；And to being generated in waste gas treatment process
Waste water realize zero-emission, mitigate old and useless battery and regenerate pollution on the environment；
(3) present invention with winnowing machine inner wall to sub-pressure selective plastic diaphragms by carrying out preservative treatment to enhance its anti-corrosive properties
Can, corrosion of the hydrofluoric acid to winnowing machine inner wall is avoided, to extend the service life of winnowing machine.
