Abstract
The invention provides a process for treating waste lead accumulator through continuous solid phase electrolysis of rotating cathode. Continuous solid phase electrolysis is to carry out in the electrolytic cell of steel, and electrolyte is NaOH solution. Rotating cathode is rolled and is formed by two layers of steel plate, and internal layer is drilled with hole, and is furnished with hurricane band, to carry, stir pole plate. The waste lead accumulator pole plate transforming through desulfurization is broken apart without CX or M.A, directly joins rotating cathode, and the grid of pole plate is separated with lead plaster machinery. Make lead plaster secondary deep desulfurization conversion through chemistry and electrochemical method, as disperseing evenly free being suspended in electrolyte of solid phase lead plaster, various leaded compounds in lead plaster, obtain electricity lead and are deposited on rotating cathode surface through solid phase electroreduction. Grid after de-cream is in rotating cathode automatically drain tank. On rotating cathode, obtain like this two products: electricity is plumbous, metal simultaneously. Technical process is simple and reliable, produces and carries out continuously. Pollution to environment while having eliminated plumbous smelting. Metal recovery rate is high, and small investment, instant effect are applicable to large-scale industrial production.
Description
Technical field
The invention belongs to containing scrap lead Solid phase electrolysis field of metallurgy. Reclaim lead and the metal in waste lead accumulator in hydrometallurgy mode.
Background technology
From waste lead accumulator, reclaim lead, traditional method is fire reduction melting. The method high-temperature operation, emits a large amount of sulfur dioxide and lead steam when smelting, cause severe environmental pollution, operator's lead poisoning, and metal recovery rate is low, and energy consumption is large.
The problem existing in order to solve pyrometallurgical smelting of lead, has extensively carried out the research of hydrometallurgical extraction metallic lead. But the method flow of research is long, and production cost, higher than pyrogenic process, even to this day, does not also find and is more preferably applicable to technology and equipment large-scale production, rational in infrastructure.
Mineral bureau of U.S. roller research center, waste lead accumulator is broken apart through M.A, electrode plate grid is separated with lead plaster, lead plaster transforms through desulfurization, and acid-soluble electrodeposition obtains electric lead. Grid fusing, makes positive plate, carries out electrorefining, obtains lead bullion. Carry out commerical test.
Half industrial production test of Engitec company of Italy, waste lead accumulator is broken apart through CX, lead plaster Na2Co3Carry out desulfurization conversion, use HBF4Leach, form Pb(BF4)2, the electrolysis of solutions, obtains electricity plumbous.
In China, smelting institute of Chinese Academy of Sciences lead-containing material Solid phase electrolysis is processed waste lead accumulator technique. Waste lead accumulator, through M.A cracking and sorting, obtains grid and lead plaster, and grid melts to obtain metal, and slag yield 20%, as returning charge. Lead plaster transforms and makes minus plate through desulfurization, and alkaline solution Solid phase electrolysis obtains electricity plumbous, has realized industrial production. Electrolysing period is 20 hours, produces intermittently and carries out.
Above three technical process, have all adopted the broken apart system of CX or M.A, and lead plaster desulfurization transforms, and it is plumbous that acid-soluble or alkaline solution Solid phase electrolysis obtains electricity, complex technical process. A set of Small-sized C X device, 5 tons of waste lead accumulators of little processing when per, gross weight of equipment is 50 tons.
Summary of the invention
In order to solve the problem of above-mentioned existence, special invention process for treating waste lead accumulator through continuous solid phase electrolysis of rotating cathode. this technical process and equipment is as shown in the figure: 1 charge door, 2 pole plates, 3 electrolytic cells, 4 electrolyte, 5 positive plates, 6 rotating cathodes, 7 electricity lead, 8 contact rods, 9 hurricane bands, 10 grid aggregate bins, 11 discharging openings, 12 rotating shafts, 13 conducting rings, 14 grids in figure. technical process is described in detail as follows: the pole plate (2) transforming through desulfurization joins in rotating cathode (6) by charge door (1), rotating cathode (6) is to be rolled and formed by two layers of steel plate, internal layer is drilled with hole, (6) in, be furnished with hurricane band (9), so that pole plate (2) is shifted to discharging opening (11) from charge door (1), pole plate (2) ceaselessly moves in rotating cathode (6), rolling, grind mutually collision, grid (14) in pole plate (2) is separated with lead plaster machinery, lead plaster is as disperseing evenly free being suspended in electrolyte (4) of solid phase, through Solid phase electrolysis, plumbous electroreduction in lead plaster in various lead-containing compounds becomes electricity plumbous (7) to be deposited on rotating cathode (6) surface. grid (14) after de-cream is to be collected by the grid aggregate bin (10) of rotating cathode (6) afterbody, while being promoted to peak, grid (14) freely falls at discharging opening (11) upper, by manually taking off. on rotating cathode (6), obtain like this two products, electricity plumbous (7) and grid (14) simultaneously. producing is because hurricane band is ceaselessly being carried pole plate continuously. hurricane band (9) external diameter 1200mm, internal diameter Φ 800mm, pitch 400mm, total length 82m.
Cloudy plate power configuration mode: rectifier power supply (-) → conducting ring → rotating shaft → contact rod → hurricane band → rotating cathode (-). Anode is made up of corrosion resistant plate.
Below the application example of process for treating waste lead accumulator through continuous solid phase electrolysis of rotating cathode:
Waste lead accumulator is broken apart without CX or M.A, transforms acquisition pole plate directly join in rotating cathode and produce through desulfurization, and process conditions are: NaOH concentration 150g/L, 40～50 DEG C of electrolyte temperatures, tank voltage 2.5～3V, cathode-current density 200A/m2, die opening 60mm, processing pole plate 72Kg per hour, directly obtains electric lead and metal. Electricity lead deposit is on rotating cathode surface, and because equipment is huge, depositing electric lead cannot accurate-metering, and the clean light of grid, automatically, outside drain tank, produces and carry out continuously, and machine operation is good.
In brief, pole plate (2) is processed and is directly obtained electricity plumbous (7) and (14) two products of grid by rotating cathode (6) processing, (2) and (14) can separate completely, technical process is exactly simple like this. It is worth mentioning especially, key equipment rotating cathode of the present invention, it has replaced CX or M.A device, completes multinomial technical process, and production is carried out continuously.
