Description
Technical field
The present invention relates to a kind of circulation producing method of lead-acid battery, its objective is from root and eliminate the environmental hazard that waste lead acid battery may exist, make cheap and good-quality lead-acid battery can continue to play a role in social life, and do not bring any lead, the sulfate pollution problem.
Background technology
Lead-acid battery (Lead-acid battery) electrode is mainly made by lead and oxide thereof, and electrolyte is a kind of storage battery of sulfuric acid solution.Special (G.Plante) was in invention lead acid accumulator in 1859 from the Frenchman Pulan, experienced nearly 150 years development course, lead acid accumulator is aspect theory research, all obtained significant progress at aspects such as product category and kind, product electric properties, no matter be in traffic, communication, electric power, military affairs or in navigation, each economic field of aviation, lead acid accumulator has all played indispensable important function.In recent years, along with the acceleration of urbanization and the expansion of city scope, the magnitude of traffic flow increases severely.Advantages such as although the vehicles such as automobile development, is subject to using rapidly the impact of the factor such as the relatively costly and rise of the oil price of price, makes electric bicycle spry and light with it, and are convenient, cheap, city's field depth is subjected to consumers in general's welcome at home.Lead-acid battery is because cost performance is high, power characteristic is good, self discharge is little, low price, the application of having got back in electric bicycle in recent years also can not be replaced by other rechargeable battery for a comparatively long period of time, belongs to the high pollution risk but the typical industry that can't eliminate at once.But lead-acid battery exists specific power low, can not fast charging and discharging etc. deficiency, wherein deadly defect is that active material PbSO4 on the electrode can pollute pole plate gradually, makes it normal chemical reaction can not occur, and the SO42-in the electrolyte forms PbSO4 through reaction, and Step crystallization is attached on the electrode, namely cause usually said sulfation (Sulfation), because sulfation causes that electrolyte quality concentration descends, and along with the reduction of electrolyte quality concentration, voltage also reduces.Therefore, the battery of performance degradation has a large amount of electric currents to pass through when charging, cause the cell reaction of water, liquid temperature rises to 50～60 ℃, can produce a large amount of hydrogen and oxygen, and continues to occur the state of undercharge, make the PbSO4 Step crystallization, when the large crystalline solid of this PbSO4 white covers whole electrode surface, even continue charging, can not recover battery performance.Sulfation is so that battery capacity and current characteristics worsen, and performance progressively reduces.Use after a period of time, the electric weight that lead-acid battery can store and emit can greatly reduce, and no longer can satisfy user's requirement, and this is waste lead acid battery.It is generally acknowledged that lead-acid battery is in normal use procedure, owing to not exclusively discharge and recharge or when being in for a long time state to be used, its inside battery can constantly produce crystallization sulfide, and crystallization sulfide covers the normal operation that has hindered electrochemical reaction on the pole plate, and affects the output of electric energy.And along with being on the increase of crystallization sulfide on the pole plate, the capacity of lead-acid battery can constantly descend, until till the complete failure.In addition, the negative plate of lead-acid battery can produce lead sulfate in when discharge when lead oxide and sulfuric acid solution carry out electrochemical reaction, and the lead sulfate material is to exist with crystallization mode.Usually, because slowly discharge formed bulky grain lead sulfate crystallization and excessive large current charge all can cause too closely lead sulfate crystallization with discharge.Active material be can cover when oarse-grained lead sulfate crystallization is covered in above the negative plate, thereby the phenomenon of sulfuration or title " false electric weight phenomenon " produced.When if the level of coverage of lead-acid battery strengthens, then can lose gradually the charging and discharging capabilities of electric charge.In the present lead-acid battery, the reason of its life termination have belong to more than 70% the sulfuration caused.Existing technology will only have to disassemble by battery and process.At present, more existing industrialized technology are recycled this waste lead acid battery.In existing lead-acid battery recovery scheme, the characteristics that normal operation metallic lead fusing point is lower (only having 327.4 ℃) are the plumbous recovery of the overwhelming majority in the waste lead acid battery.And other composition in the lead-acid battery, must be after desulfurization such as lead sulfate, brown lead oxide etc., again by the existing smelting splicer smelting lead of planting.Can consume a certain amount of sodium carbonate or NaOH etc. so on the one hand, produce simultaneously a considerable amount of low value sodium sulphate or ammonium sulfate, economic benefit is had a greatly reduced quality.In addition, even other problems has all obtained solution, the lead that reduction obtains must obtain lead oxide through powder process, oxidation respectively, could be applied in lead-acid battery, therefore exists technological process long, and risk of environmental pollution is high, the problem that energy consumption is high.In addition, international and domestic some wet processings of also having developed.For example, Chinese patent application CN101291008A a kind of so-called acid wet method electrolysis of just having reported for work reclaims method plumbous in the waste lead acid battery.The method obtains lead with the battery unit that separation obtains with the reduction of duplicate supply multimode electrolysis process.The method has a shortcoming, is exactly that all lead-containing compounds all change lead into, this means and will expend a large amount of electric energy, also has foregoing problem simultaneously.However, the recycling of lead-acid battery also involves a large amount of technology, economy and environment protection factor, if method is improper, may cause low in economic efficiency and problem secondary environmental pollution.According to investigations, the little purchase family of some old and useless batterys through wandering about the streets flows to some little reviver factories from electric motor car producer and electric motor car maintenace point.Some little reviver factory does not have refuse battery and disposes qualification; add that some little purchase self-employed workers generally lack environmental protection consciousness; in collection, transport process, arbitrarily disassemble; poisonous acid solution in the waste and old lead acid accumulator is disposed arbitrarily; therefore there is serious risk of environmental pollution in removal process, may seriously jeopardize health.For the problem that the old and useless battery Resource analysis exists, we have taken the lead in proposing the concept of environmental protection recyclable regenerative battery.Its core concept is that the resource of secondary cell is no longer to extract wherein noble element as target, what replace it is that old and useless battery is not disassembled, do not topple over malicious acid solution, by a kind of method and device that utilizes ultrasonic wave that storage battery is discharged and recharged, thereby the waste and old lead acid accumulator of sulfation is transformed into environmental protection recyclable regenerative battery.
