- the actual process for shredding the batteries and separating the components is initially preceded by a preliminary process 1, which is described in the schematic representation according to FIG.
- batteries 2 originating from vehicles which have, for example, reached the end of their service life, and possibly battery cells and/or battery modules which were sorted out during production and require dismantling, are first dismantled.
- These batteries, battery cells and/or battery modules 2, which will be understood below under the general term batteries 2 are discharged once, if necessary after the type has been identified (step 3), (step 4), but according to the invention, this is deliberately not a complete discharge Discharge is provided because this - as already explained - is very complex. In addition, it was surprisingly found that complete discharge is not necessary for the subsequent processing process.
- the productivity of a corresponding system can be significantly increased.
- the electrical energy 5 obtained when the batteries 2 are partially discharged can be used for other purposes become.
- the other components 7 of the batteries 2 that arise during dismantling 6, such as in particular the housing, the cabling, fittings and the like, are sorted and fed into the circular economy.
- the different materials are separated from each other and sorted (step 8), whereby the residual materials 9, which are then separated according to type, can then be recycled.
- the batteries, battery cells and/or battery modules 10 separated from the batteries 2 in this pre-process are then fed to the first sub-process 11, which is described in Figure 2 and will be explained below based on this representation.
- the isolated batteries, battery cells and/or battery modules which will be understood below under the general term isolated batteries 10, are first mixed with water 12 and preferably comminuted in a multi-stage comminution process 13, for example by means of a shredder.
- the water 12 is constantly supplied and serves, among other things, to dissipate the heat generated in the process so that hydrogen fluoride (HF for short) is not released.
- the mixture comprising the comminuted batteries and the water can be separated into a first aqueous graphite-enriched fraction 15 and a second non-aqueous graphite-depleted fraction 16 (separation step 14), for example in which the mixture centrifuged and spun.
- the first aqueous graphite-enriched fraction 15 obtained according to the separation step 14, which contains the majority of the black mass, preferably comprises particulate components with a size of ⁇ 3 mm
- the second non-aqueous graphite-depleted fraction 16 preferably includes particulate components with a size of > 3 mm.
- the first aqueous graphite-enriched fraction 15 can be freed directly from the water according to a drying step 17, so that a dried graphite-containing fraction 18, which contains the majority of the black mass, is obtained.
- black mass refers to the mostly valuable raw materials that can then be separated in a wet chemical process, as shown in Figure 5.
- the first aqueous graphite-enriched fraction 15 can also first be separated into a first aqueous graphite-enriched fraction 19 freed from the particulate components and into a non-aqueous graphite-depleted fraction 20 loaded with the particulate components. For example, this can be screened in several steps, first coarsely (step 21) and then finely (step 22) in order to obtain the non-aqueous graphite-depleted fraction 20 loaded with the particulate components.
- the then obtained first aqueous graphite-enriched fraction 19 freed from the particulate components can then be freed of the water, for example by pressing (step 23).
- the contaminated water 24 can be returned to the water cycle and used again in the process after it has optionally been cleaned and treated using suitable measures (step 25).
- the second non-aqueous graphite-depleted fraction 16 which can contain, for example, still-moist small parts with a particle size in the range of about 3 mm to about 10 mm as well as foils and metals, is fed to a second sub-process 26 for processing, which is shown in Figure 3 and will be explained in more detail below based on this illustration.
- the second non-aqueous graphite-depleted fraction 16 is separated into a light and a heavier fraction 28, 29 by means of a further separation step 27, for which purpose, for example, a cross air flow can be used when the particles are in free fall .
- the aerosol 31 that arises during the separation step or process 27 and contains part of a first graphite-containing secondary fraction 33 can be removed from the separation step 27 by a suction step 30 and filtered via a separation step 32, so that the part of the first graphite contained therein is containing secondary fraction 33 is separated, in particular filtered.
- the heavier metallic particles (heavy fraction 29), which contain the majority of the first graphite-containing secondary fraction 33, can, after the separation described above in accordance with separation step 27, be fed to a comminution device, in particular an impact mill 34, in which further comminution takes place.
- the different ones obtained here Fractions can then be separated from each other by a sieving process 35, namely into a first middle fraction with particles with a size in the range of about 250 pm to about 100 pm, a coarser fraction with particles in a size of more than 250 pm and a third finer one Fraction with particles with a size of less than 100 pm.
- the third, finer fraction then comprises the main part of the first graphite-containing secondary fraction 33, which is combined with the black mass fraction obtained after passing through the separation step or filter system 32 and can also be fed to the wet-chemical processing (see Figure 5).
- the coarser fraction shown in Figure 3 (>250 pm) generally contains predominantly plastics 37. This can be collected 38 and returned to a circular economy 39, as is also shown in Figure 3.
- the middle fraction can be further separated, for example using an air separation table and/or a magnetic separator 40, in order to collect the metals copper, aluminum and iron according to type 41.
- a third sub-process 42 is shown in FIG. 4, which describes the further processing of the non-aqueous graphite-depleted fraction 20 loaded with the particulate components (see FIG. 2). Reference will be made to this below.
- This fraction 20 can first be dried in a drying device, in particular in a vacuum dryer 43, whereby the resulting condensate water 44 can be fed to the water circuit 25.
- the material can be fed to a comminution device, in particular an impact mill 45, in which further comminution takes place.
- the comminution step is then followed by a sieving process 46 to separate the fractions obtained.
- the several fractions (for example three) can be of the same order of magnitude as in the sieving process 35 previously described with reference to FIG 100 pm, a coarser fraction comprising particles with a size of more than 250 pm and a third, finer fraction comprising particles with a size of less than 100 pm can be obtained.
- This third, finer fraction includes a further fraction 47 containing black mass, which in this case may contain water.
- the water can be removed by means of a separation step, for example by sieving and pressing 48.
- the coarser fraction usually contains predominantly plastics 50. This can be collected by type (step 51) and also fed into the circular economy 39.
- the middle fraction can be further separated, for example by means of an air separation table and/or a magnetic separator 52, in order to collect the metals copper, aluminum and iron according to type and also feed them to the circular economy 39.
- the aerosol 55 that arises during the comminution step 45 and contains part of the second graphite-containing secondary fraction 49 can be removed from it by a suction step 53 and filtered via a separation step 56, so that the part of the second graphite-containing secondary fraction 49 contained therein is separated, in particular filtered becomes.
- the black mass fraction 54 obtained after passing through the separation step or filter system 56 can also be combined directly or, if necessary, with the remaining fractions 18, 33, 49 and then fed to the wet chemical processing (see Figure 5).
- the individual or possibly combined black mass-containing fractions 18, 33, 49, 54 can be brought into solution, for example, using aqueous sulfuric acid, ammonia, hydrogen peroxide and/or using organic solvents 58 (step 59) and then a sieving and/or filtering process 60 will be subjected.
- Graphite 61 can be separated, collected 62 and returned to the circular economy 39.
- the metals 63 obtained after this separation are located in a solution whose pH value may be adjusted accordingly depending on the metal (step 64).
- An extraction 65 can then take place, in which the metals can be obtained, for example, as metal sulfates and crystallized or extracted again. Adjusting the pH value (step 64) depending on the metal and extraction can be done in several stages.
- a friction washer 76 which includes a screw conveyor equipped with paddles.
- the friction washer 76 includes a sieve arranged below the inclined conveyor screw. If the shredded material, in particular the mixture comprising the shredded batteries and the water, is conveyed by means of the screw conveyor from the input end 75 to the axially opposite output end 77 of the screw conveyor (from left to right in the drawing), then the finer material falls with a particle size of for example less than 1 to less than 3 mm (for example the first aqueous graphite-enriched fraction 15) through the sieve and reaches a buffer tank 79 via a line 78 below the inlet end 75.
- the fraction of finer particles with a size of, for example, less than 1 to less than 3 mm is conveyed by means of a pump 82 to a sieve 83, by means of which a further separation into the two fractions 19, 20 takes place, namely a fraction 19 with a particle size of less than, for example, 500 pm, which contains the largest part, for example about 95% of the black mass and about 5% metals, and a fraction 20 with a particle size of more than, for example, 500 pm, which contains metals such as copper and aluminum as well as plastics contains adhering black mass.
- This fraction 20 is fed via line 84 and screw conveyor 85 to the third sub-process 42, which will be explained in more detail later with reference to FIG.
- the heat exchanger 96 is in Countercurrent of hot tap water flows through, which reaches the heat exchanger 96 via line 98, so that the returned material flow can be preheated in this way.
- the product of the process shown in Figure 7 is the dried fraction 18 containing black mass, which leaves the filter press 91 via line 99 and can be temporarily stored in a barrel 100.
- the black mass is already quite high in purity, for example around 95%, with a residual moisture in the range of around 20% to 30%.
- This fraction 18 containing black mass can be used as feed material for a further wet chemical processing process, which is shown in FIG. 5 and has already been described above.
- the further separation process 26 relating to the fraction of the coarse material 16 resulting after the first shredding process according to FIG. 6 is explained in more detail below with reference to FIG. 8.
- This separation process 26 primarily serves to separate the separator film of the isolated batteries 10 from the plastic and metal particles.
- the coarse fraction first travels from the silo 81 via line 101 to a cyclone 102, in which centrifugal separation takes place.
- the fraction is then fed to a zigzag separator 103, in which the metals and plastics are separated using a process that exploits the density differences. In free fall, transverse air currents separate the heavier metals from the lighter plastic and film residues.
- the black mass on the metals can then be chipped off in an impact mill, as has already been explained with reference to FIG. 3.
- the medium-coarse fraction 20 separated in the separation process according to FIG contains is further treated in the process according to Figure 9, which is explained in more detail below.
- This material reaches a vacuum dryer 111 via the feed line 110, in which it is dried.
- the dry black mass fraction 49 obtained can be fed from the vacuum dryer 111 via line 112 to a barrel 113, in which it is collected. From there, this black mass fraction 49 can be fed via the output line 114 to the black mass fractions obtained in the other separation processes and processed wet-chemically, as has already been described with reference to FIG. 5.
- the water vapor separated in the vacuum dryer 111 can be fed via line 115 to a condenser 116 and condensed there, in order to then be collected in the condensate tank 117.
- Industrial cooling water can be used to cool the water vapor, which is fed to the condenser 116 via line 118.
