Description
Technical field:
The invention belongs to chemical field, relate in particular to a kind of plumbous technology that reclaims, is a kind of desulfurization and transformation method of waste lead accumulator specifically.
Background technology:
Secondary lead raw material 80% comes from waste lead accumulator, and waste lead accumulator is classified and sub-elects stereotype grid, plumbous mud, polychloroprene shell, plastics, spent acid by MA cracking and sorting system.There is a certain amount of lead sulfate in the plumbous mud, the plumbous temperature that will restore fully in the lead sulfate need be more than 1200 ℃, not only to consume a large amount of energy, and also have a large amount of lead to be evaporated to enter furnace gas, repeat to gather dust and repeat to smelt, the repetition and waste energy, input, operation, maintenance and the energy very expensive of handling the environmental protection equipment of these leaded furnace gases is if handle the loss that can further cause lead resource not up to standard and to the pollution of environment.
The desulfurization transformation technology of waste lead accumulator regenerative lead production advanced country abroad generally adopts, typically by the CX automatization store battery fragmentation and the recovery system of the exploitation of Italian Engitec research and development company, this system is the annual waste lead accumulator of handling more than 1,200,000 tons in the whole world.The CX system combines the whole store battery fragmentation of automatization, component separation and lead plaster desulfurization, sodium sulfate manufacturing, and this complete system can reach environmental requirement, can improve the plumbous production and the recovery of byproduct, output sodium sulfate byproduct.The CX secondary lead system of Italy Engitec research and development company exploitation, it as an important composition of system, is delivered to plumbous mud desulfurization and sodium sulfate production in the reactive tank with plumbous slush pump, mixes with the spent acid of collecting at the store battery storage area.Desulphurization reaction can be finished with two kinds of different reagents respectively, i.e. sodium hydroxide and yellow soda ash.The reaction that takes place in reactor is very fast, but in batch treatment, be about 1 hour duration of contact that needs.Fast because of speed of response, this operation can be carried out continuously, can reduce the volume of reactor and improve reaction efficiency under the condition that keeps constant parameter.Stay residual sulfur in the lead plaster less than 0.3%, the sulphur content in the initial lead plaster is about 6%, and the clearance of sulphur is greater than 95%.Reacted plumbous dredge pump is delivered in the pressure filter and is dewatered, for smelting furnace is supplied raw materials.Metabisulfite solution after the filtration, storage is then delivered to Crystallization Procedure in groove.The byproduct that this recovery technology produces is a sodium sulfate, but being limited in scope of using of sodium sulfate, and how handling sodium sulfate becomes a new problem again.
Summary of the invention:
The object of the present invention is to provide a kind of desulfurization and transformation method of waste lead accumulator regenerative lead, the desulfurization and transformation method of described this waste lead accumulator regenerative lead will solve in the prior art handles the technical problem how byproduct sulfite that produces behind the waste lead accumulator is handled, and handles waste lead accumulator complex process and the high technical problem of expense.
The desulfurization and transformation method of a kind of waste lead accumulator regenerative lead of the present invention, comprise a process with the waste lead accumulator fragmentation, the plumbous material-mud that broken back produces carries out liquid-solid separation back and produces wet plumbous mud, the plumbous mud that will wet is put into a desulfurizer, in described desulfurizer, put into sweetening agent yellow soda ash, stir, fully reaction, carry out liquid-solid separation after leaving standstill, obtain throw out lead carbonate and fluid sulphuric acid sodium, fluid sulphuric acid sodium is put into a reactor, in reactor, add barium carbonate, stir, fully reaction is left standstill, carry out liquid-solid separation, obtain throw out barium sulfate and liquid carbonic acid sodium, described liquid carbonic acid sodium is sent in the desulfurizer, continues to recycle as sweetening agent.
Further, carrying out in the process of desulfurization for the first time, the add-on of yellow soda ash is the twice of the mole number of lead sulfate in the plumbous mud.
Further, plumbous material-mud is sent into desulfurizer by the wet plumbous mud that press filtration or band filter carry out after the liquid-solid separation, add entry and sweetening agent yellow soda ash by desulfurization formulation, open stirrer, after use earlier is stirred to the interior basic pulping of plumbous mud of groove at a slow speed, carrying out the stirring of high speed speed change again makes slurry even, treat that slurry evenly continues to stir 20-50 minute in the back, stopped to stir 15-20 minute, and then with 120-180 rev/min of speed stirring 10-30 minute, treat that slurry is once more behind the pulping, stir with 300-400 rev/min of high speed speed change, plumbous mud and sweetening agent fully react, the high speed speed change stirs and stops after 30-70 minute stirring, inactive slurry 10-30 minute, after interior slurry of groove to be desulfurization and the liquid layering, extract the shallow lake fluid to reservoir, in desulfurizer, add simultaneously entry, stir, carry out then leaving standstill the second time, extract the shallow lake fluid to reservoir, solid is the plumbous mud after the desulfurization, liquid in the reservoir is filtered, liquid after the filtration is sent in the reactor, adds barium carbonate and fully stirs, and the slurry sediment quality testing is surveyed, while test liquid pH value, detect qualified after, slurry is carried out liquid-solid separation, leach byproduct barium sulfate, liquid in the reactor is regenerated yellow soda ash, regenerated yellow soda ash is sent into desulfurizer continue to recycle.Concrete, the add-on of sweetening agent yellow soda ash is the twice of the mole number of lead sulfate in the wet plumbous mud.
