Description
Technical field
The present invention relates to the recycling of old and useless article, particularly relate to the recycling of waste and old lead acid accumulator lead plaster.
Background technology
Along with the fast development in communication, electric power, automobile, railway and energy source and power field, the demand of various lead acid cells continues to increase, and all kinds of waste and old lead acid accumulator quantity are corresponding increasing also.At present; ten thousand of the annual about 5000-6000 of all kinds of waste and old lead acid accumulators that produces of China, weight reaches 300,000 tons approximately, these lead-acid accumulators; if rationally do not utilize and reclaim, the pollution that causes will constitute huge threat to environment protection, the eubiosis and HUMAN HEALTH.And China's lead ore resource is deficient relatively, needs dependence on import to replenish the deficiency of lead ore resource, therefore, advance plumbous recycling seem particularly urgently with highly significant.The recovery of lead acid cell relates to the processing of lead-acid cell lead plaster in order to isolate lead from old and useless battery.Often adopt some physical sepn and chemical treatment method, for example hydrometallurgical, electrowinning and melting (pyrometallurgical smelting method) etc.
Pyrometallurgical smelting method commonly used, with the battery lead plaster put into smelting furnace and at a certain temperature fusion and decomposition obtain metallic lead.The type of furnace of melting mainly contains the professional type of furnaces such as reverberatory furnace, the short stove of revolution, blast furnace.And PbSO in the waste and old lead plaster
4Content is generally more than 50%, PbSO
4The fusing point height, reaching the temperature of decomposing fully will can produce a large amount of SO in the smelting process more than 1000 ℃
2, also can cause a large amount of plumbous loss through volatilizationes under the high temperature and produce lead dust to form pollution.China's secondary lead number of the enterprise reaches several hundred families, but most of scale is less, and annual production does not wait from tens tons to several kilotons.Domestic little secondary lead factory produces 1 ton of general energy consumption of lead and is about 500～600 kilograms of standard coals, and the secondary lead enterprise energy consumption of specialty is about 200～310 kg/ton, and the energy consumption level of foreign technology can reach below 200 kg/ton.Therefore, PbSO
4Pyrometallurgical method be that many drawbacks are arranged, the one, secondary lead technology is the energy consumption height not only, but also can produce SO
2Sour gas, CO
2Atmospheric polluting materials such as greenhouse gases and volatility lead steam, lead dust need extra step to prevent SO
2Discharge into outside atmosphere, high-temperature process also can produce a large amount of harmful plumbous pollutents such as smog, dust and waste residue that carry, these pollutents surpass tens times of discharging standards this can have a strong impact on the healthy of surrounding environment and people; And the emission control of these harmful side products is comparatively difficult and strict, wastes time and energy very much usually, and needs very expensive specific equipment, and three wastes discharge amount is bigger, produces slag and handles relatively difficulty, is difficult to satisfied severe day by day environmental protection requirement; The 2nd, lead recovery is low.The rate of recovery is generally 80～85%, and annual nearly lead more than 10,000 tons is depleted in melting.
In recent years, some scholars introduce the hydrometallurgical recovery technology of electrodeposition method, hydrometallurgical has been used to remove element sulphur in the battery scrap lead cream with the form of soluble metal vitriol, soluble metal vitriol is separated from the insoluble plumbous product that the recycling process produces, solved the SO in the lead plaster pyrometallurgical smelting process
2The volatilization problem of lead under discharging and the high temperature.The syllogic of the plumbous process using desulfurization conversion-reduction conversion-electrodeposition method that reclaims of at present typical wet method, this technology investment is big, difficult control, the cycle is long, the power consumption height, alkaline consumption is big, is difficult to large-scale production.1 kilogram of plumbous energy consumption of hydrometallurgical recovery reaches 12 kilowatt-hours, even more taller than traditional fire metallurgy process.Therefore, the problem of high energy consumption still has to be solved.And because the transformation efficiency problem that desulfurization transforms, the plumbous product of collecting often keeps a large amount of sulphur of some forms, if the product of collecting is placed smelting furnace, still must take some particular processing methods to guarantee SO
2Discharging fully handled, this relatively the difficulty and also expend very big.
Reclaim the various environmental problems of bringing for solving, some scholar introduces electrowinning, has solved the SO in the lead plaster pyrometallurgical smelting process
2The volatilization problem of lead under discharging and the high temperature.But owing to need complicated chemical that lead is dissolved into the form that is suitable for handling in battery, itself also belong to energy intensive.This technology investment is big, difficult control, and the cycle is long, the power consumption height, alkaline consumption is big, is difficult to large-scale production.
In addition, the metal Pb that prior art waste and old lead acid accumulator lead plaster reclaims is applied in the store battery production, needs through fusion-oxidation, and often being prepared into PbO by ball milled or vapour phase oxidation process is the lead powder of main component, consumed energy again.Described ball milled refers to because shot or the mutual friction of lead phase and a large amount of heat of bump generation in lead-power machine, make the interior temperature of cylindrical shell increase, give under the effect of oxygen in the air draught of importing certain temperature and humidity in the lead-power machine again, thereby oxidation takes place and generates PbO in shot or lead surface.The plumbous liquid that described vapour phase oxidation process refers to fusion is made the process of lead powder with airborne oxygen reaction after being stirred into the droplet shape in that gaseous oxidation is indoor.The PbO massfraction is about 75% in the general control lead powder, and described PbO massfraction is also referred to as the oxidisability of lead powder.
