Description
Technical field
The present invention relates to a kind of lead-acid accumulator recycling and reclaim plumbous method, belong to the lead-acid accumulator recovery, to containing the treatment technology of scrap lead, particularly hydrometallurgic recovery contains lead in the scrap lead, is scrap lead material reviver field of metallurgy, the Applied Electrochemistry principle is handled lead-acid accumulator and output high-grade metal lead.
Background technology
Along with a large amount of generations of lead-acid accumulator, the recycling of lead-acid accumulator is more and more extremely paid attention to.The one, because abandoning of lead-acid accumulator itself is substantial pollution to environment; The 2nd, because because plumbous valency unprecedented soaring extremely paid attention to plumbous recycling, the secondary pollution that local method is returned has also produced environment and has had a strong impact on.Therefore, recycling of environment-friendly type heavy industrialization lead-acid accumulator and the plumbous technology of recovery are the problems that present countries in the world are paid close attention to.
The technological core of recycling lead of abandoned lead acid accumulator is the processing of lead plaster, and the wet treatment lead plaster reclaims the plumbous concern that always is subjected to reviver industry.Lead plaster is through the carbonating desulfurization in the eighties U.S. proposition lead-acid accumulator, and with the silicofluoric acid dissolving, gained silicofluoric acid lead solution adopts the plumbous achieving success of insoluble anode electrolysis output electricity.This method operation is more, the specification requirement height, and equipment is huge and complicated, and energy consumption and reagent consumption are also bigger.
German patent DE 3402338A application accumulator negative plate changes into principle and proposes the scrap battery lead plaster is pressed solidly on a metallic plate, in dilution heat of sulfuric acid, carry out the solid phase reduction electrolysis as negative electrode, reclaim sulfuric acid when obtaining metallic lead, but because of lead sulfate solubility limit in diluted acid, current density and pressure layer thickness are all less, cause that utilization rate of equipment and installations is low, little, the groove of the reduction degree of depth press high, energy consumption is big, and reclaim sulfuric acid concentration is low, therefore limits its industry and promotes.
Chinese patent CN 1038505A has proposed the method for electroreduction lead plaster in alkaline solution, but there is obviously deficiency in this technology: the preliminary treatment trouble of lead plaster comprises plumbic prereduction and pre-batching; Adopt filter-press type electrolysis heaping equipment, the bed of material is thin, and the loading and unloading material is loaded down with trivial details, and it is frequent to go out tankage, and industrial being difficult to used.At present, the electroreduction method all is based on the notion of intrinsic constant-current electrolysis, and tank voltage rises gradually with the carrying out of reduction process.The cooling economize on electricity of electroreduction method also is a key problem in technology.
The plumbous easily oxidation of electroreduction, how making the high lead pig of purity also is key problem in technology.
Summary of the invention
The purpose of this invention is to provide a kind of lead-acid accumulator recycling and reclaim plumbous method, particularly solve the heavy industrialization lead-acid accumulator recycling of key technologies such as energy-saving and environmental protection and high-recovery and reclaim plumbous method, make the high lead pig of purity at last.
Technical scheme of the present invention is: lead-acid accumulator of the present invention recycles and reclaims plumbous method, the broken apart technology, conversion process, the press filtration that comprise lead-acid accumulator are coated with cream technique, lead plaster reducing process, fusion casting ingot process, water treatment and soda acid recovery technology, the lead plaster reducing process is that lead plaster is coated in the pole plate negative pole, the tandem type electrolytic tank electrolysis output lead that adopts no lead to connect, electrolyte adopts NaOH; The electrolysis lead powder is immersed in the sodium hydroxide solution, electrolysis lead powder fusion casting ingot process is that the lead powder that soaks sodium hydroxide solution is inserted heating kettle, melt temperature is between 400～420 ℃, and melting process constantly adds NaOH, and sodium hydroxide solution covers above the plumbous liquid of fusion anti-oxidation.
Described lead-acid accumulator recycling and lead recovery method comprise the sink-float separator in the broken apart technology, isolate plastics recovery, lead-containing material enters vibrating screen, sift out two kinds of products that granularity is different, granularity is lead and alloy thereof greater than 7mm's, directly delivers to a heating kettle fusion ingot casting; Granularity rescreens pulverizing through pulverizer of 1～7mm; Granularity obtains lead plaster less than the material of 1mm after desulfurization.
Described lead-acid accumulator recycling and lead recovery method,: insulated enclosure between the electrolysis tank of tandem type electrolytic tank, face mutually the pole plate patchhole is arranged on the division board, pole plate is the division board between the tank house, be again the battery lead plate of tank house simultaneously, the one side of battery lead plate is a tank house positive pole, and the another side of battery lead plate then is the negative pole of adjacent another tank house.
Described lead-acid accumulator recycling and lead recovery method, the lead skim that the fusion casting ingot process floats over plumbous liquid surface in the heating kettle is discharged by the slag notch of heating kettle and is entered watch-quench tank, efflorescence in the sodium hydroxide solution of lead skim in watch-quench tank is taken out after the efflorescence lead skim through mixes utilization again behind the ball milling with the lead plaster raw material.
Described lead-acid accumulator recycling and lead recovery method, the poor electrolyte after the electrolysis return storage alkali jar, re-use through adjusting.
Advantage of the present invention: the present invention actually designs for prerequisite to produce, technology and equipment have been simplified, improved efficient, save power consumption, closed cycle has improved the plumbous rate of recovery, reclaims plumbous purity and satisfies the requirement that Battery Plant makes pole plate fully, not only saved lead resource, more Battery Plant has reduced cost.Particularly realize recycling of heavy industrialization lead-acid accumulator and plumbous the recovery, eliminated three wastes source, solved refining lead contamination problem, reached the purpose of complete pollution-free environmental protection recycling.
Embodiment
