Definitions
- the invention relates to a method for the continuous separation of magnetizable paramagnetic and / or diamagnetic particles from a fluid stream loaded with the particles, which is passed through a separation region penetrated by a high gradient magnetic field along a main flow path, according to the preamble of claim 1.
- a non-generic method which is mainly used for kaolin cleaning, is known, which does not work continuously, but cyclically with high gradient magnetic separators, the magnetizable particles being deposited on the steel wool filling and the latter therefore having to be rinsed cyclically.
- the processing of substances with a high proportion of magnetizable particles becomes uneconomical due to the short cycle times.
- a method of the generic type is known from US Pat. No. 4,261,815, which operates with high field gradients for continuous magnetic separation.
- the device of a magnetic separator specified for its implementation consists of a first matrix of wires perpendicular to the magnetic field for generating field gradients and particle deflection and a second grid matrix for separating the particle streams flowing in the wire direction.
- the first and second matrix form the flow guide matrix, the main problem with this known device in the difficult manufacture of the plurality of thin wires arranged parallel to the axis, the diameter of which is e.g. Is 0.2 mm and their distances from each other e.g. Amount to 2 mm.
- the high-performance magnetic field passes through the tubular magnetic separator in the transverse direction, the housing of which is accordingly made of non-magnetic material. Due to the difficult arrangement in its interior, a method using such a magnetic separator is relatively dirt-prone and therefore susceptible to failure in continuous operation.
- a second variant of a flow guide matrix for the deposition process according to the aforementioned US PS is published in the magazine "IEEE Trans. Magn. MAG 19, 2127 (1983) and also consists of a wire grid matrix, the magnetic field being applied perpendicular to the wire direction and
- the separation of the particles is also mentioned by means of repulsive magnetic forces.
- the range of attractive forces is covered by plates made of non-magnetizable material.
- the object of the invention is to design it in such a way that the problem of the continuous concentration of magnetizable particles in the range of forces of the high gradient magnetic separators can be realized in a more robust and less prone to clogging manner and therefore overall with a better efficiency.
- the object is achieved in a generic method according to claim 1 by the features specified in the characterizing part of claim 1.
- the invention also relates to a device for carrying out the method according to claim 1, as described in the preamble of claim 2 and known in principle by the aforementioned US Pat. No. 4,261,815.
- this device defined in the preamble of claim 1, the object of creating a particularly advantageous, process- and production-friendly and robust device for carrying out the method according to the invention is achieved according to the invention by the features specified in the characterizing part of claim 2.
- Advantageous developments of the subject matter of claim 2 are specified in subclaims 3 to 20.
- the device shown in Figures 1 to 8 implements a method according to claim 1.
- the core of this device of a continuous magnetic separator is a perforated plate-like fine structure, which serves both for the formation of the magnetic field gradients required for the separation and also leads the partial currents enriched and depleted in magnetizable material.
- the fine structure of the flow guide matrix has separating perforated fields designated as a whole and feed perforated fields ZL arranged therebetween in the direction of the main flow path z.
- the pole body orifices 1 and the pole body wall parts 2 delimiting them are formed by a perforated plate-like fine structure with hollow cone-shaped, projecting nozzles in the hole area.
- the pole body wall parts 2 consist of ferromagnetic material, the remaining wall parts 3 of the perforated sheet-like fine structure made of non-magnetizable or diamagnetic or weakly paramagnetic material.
- Another perforated plate-like fine structure for the feed perforated fields ZL has pairs of perforated plates 5 spaced plane-parallel to one another and arranged with their feed openings 4 congruent to the pole body orifices 1, the gap 6 between the paired perforated plates 5, 5 serving as the feed zone for the particle-laden fluid flow A.
- the perforated plates 3 are stacked in pairs, in particular mirror images of one another, so that the pole body openings 1 and the pole body wall parts 2 each lie on a common axis.
- the left upper pole body arrangement shows schematically the field constriction generated by the pole body designated as a whole by PK, the magnetic field designated as a whole by H, the main direction of flow of which points in the direction of the arrow f 1. Because of the local rotational symmetry, the field is narrowed even more than shown in Fig. 1, namely two-dimensionally. To the right of the schematically represented field course, the flow direction of the incoming particle-laden fluid stream A is shown schematically by broken lines.
- the magnetic forces acting on paramagnetic particles are indicated by arrows F m and bring about a concentration of the paramagnetic particles in the core current flowing into the pole body orifices, while that between the perforated plate 5 and the separating perforated field TL or the associated pole bodies PK and perforated plates 3 remaining partial stream d is depleted of paramagnetic particles.
- This partial stream d is referred to as the second branch stream and the branch stream p directed into the pole body orifices 1 is referred to as the first branch stream.
- the magnetic forces see arrows F m ), which coincide with the corresponding gradient field, act in the opposite direction, so that there is a depletion of diamagnetic particles in the core stream or first branch stream p.
- the perforated plates 5 of the feed perforated fields ZL consist of non-magnetic or diamagnetic or weakly paramagnetic material. They are arranged at a distance a1 from one another and form the feed zone A1 between them.
- the perforated plates 3 of the flow guide matrix designated as a whole by PK / 3, are likewise arranged at a distance from one another, which is designated by a2. This spacing gap forms the first collection chamber SK1 for the first branch flows p, which are designated M in the collected form.
- the flow zone arranged between the perforated plate 5 and the flow guide matrix PK / 3 is a second collecting chamber SK2 for the fraction d (second branch flow) depleted of paramagnetic particles p, and the second branch flows give the total flow NM in the second collecting chamber SK2.
- FIG. 1 shows a variant of the fine structure shown in FIG. 1, which does not work with attractive forces for paramagnetic particles, but with repulsive forces. It consists of Two pairs of perforated plates 3 ⁇ , 3 ⁇ stacked on top of each other, the particle-laden fluid flow A being fed between the thin pairs of perforated plates 5 ⁇ , 5 ⁇ made of non-magnetizable material and the fraction d depleted in paramagnetic particles between the stronger perforated plates 3 ⁇ , 3 ⁇ made of ferromagnetic material (collection chamber SK1) is discharged, however, the fraction enriched in paramagnetic particles within the collection chamber SK2.
- the magnetic field lines are locally greatly diluted, which leads to repulsive forces on paramagnetic particles, which are correspondingly depleted in the core current d.
- diamagnetic particles are enriched in the core stream.
- the perforated plates 3 provided with the pole bodies PK or PK ⁇ and the perforated plates 5 having the feed openings 4 can be combined to form modules and stacked to form a separating tube TR.
- the separating tube TR is slotted in segments to supply the incoming particle-laden fluid streams (fluid streams can in principle not only be understood to mean liquid streams but also gas streams) and to discharge the magnetic and non-magnetic fractions.
- the feed openings 4 and the polar body orifices 1 or nozzles are each one above the other in a hexagonal grid arrangement.
- FIG 4 shows, for example, favorable dimensions for a single separating tube (in millimeters).
- a large number of separating tubes of the type shown in FIG. 3 can be combined to form a separating canister, as is shown in FIG. 5 or is shown in perspective in FIG. 6, which together with the solenoid surrounding the separating canister and the supply units (not shown in detail) forms the magnetic separator.
- the particle-laden fluid stream is fed to the separating canister TK via the pipe socket 11 of a main feed line and fed to each separating pipe TR from three sides via a flow inlet plate 10 and the pipe interspaces 20, while the non-magnetic fraction is discharged separately from one another via the other pipe interspaces.
- the intermediate plate 30 (flow guide plate) separates the two fractions in such a way that the channels leading the magnetic fraction end above and the channels leading the non-magnetic fraction below the intermediate plate 30.
- the first and second main collecting lines 60 and 70 for discharging the two fractions are welded into the intermediate plate 30 and into the base plate 40 with their corresponding pipe connections.
- the six filling bodies 50 resulting from the hexagonal arrangement of the separating tubes TR can be used as pipeline in a cascade connection, compare FIG. 8, the magnetic separator consisting of several separating canisters in the magnetic field of a solenoid S.
- the cross section according to FIG. 7 shows the separating pipes TR arranged in a hexagonal grid within the separating canister, an individual separating pipe being shown in more detail.
- Both the separating pipe TR shown in FIGS. 3 and 4 and the separating canister TK shown in FIGS. 5 to 7 with their main flow paths z can be regarded as separator containers in the sense of the invention.
- the feed line function take over the line volumes v1, v2 and v3, which have the shape of columns with a ring-shaped cross section and are each limited between two successive circumferential bulkhead walls 9.
- the bulkhead walls 9 are arranged hexagonally, ie they lie on radii which span sectors with a sector angle of 60 ° between them.
- the three line volumes v1, v2 and v3 are evenly distributed over the circumference of the separating tube.
- the line volume v4 is directly adjacent and communicating with or with the second slots 8.2 for discharging the first branch flows M collected in the first collecting chambers SK1 of the modules (FIG. 1).
- the first branch flows are designated NM by definition, but this will be dealt with later.
- the dashed line indicates within the line volume v4 the exit of the first partial flows M collected in the respective modules. Seen in the clockwise direction follows the line volume v2, the line volume v5, then the line volume v3 and then the line volume v6.
- the line volumes v5 and v6 are arranged adjacent to and communicating with the third slots 8.3, that is, they serve as a collecting line for the radially emerging second partial flows NM emerging from the respective modules, as indicated by the dashed flow line in the right part of FIG. 3.
- These manifolds v5 and v6 therefore communicate with the second manifolds SK2 (see FIG 1).
- the local gradient fields H1 already mentioned are then generated by the polar bodies PK because the magnetic field lines preferably enter these ferromagnetic bodies, so that the constrictions and field line densifications shown in FIG. 1 result.
- the first paramagnetic particle group as well as the partial stream enriched with it are denoted by p and the second diamagnetic particle group as well as the partial stream enriched with it are designated by d. If one assigns the first particle group p a first magnetic susceptibility ⁇ 1 and the second particle group d a second magnetic susceptibility ⁇ 2, which differ from one another and also with respect to the magnetic susceptibility ⁇ F of the fluid or carrier fluid, then one can use the local gradient fields H1 of the polar body PK exert different magnetic deflection forces on the two groups of particles due to different magnetic dipole moments.
- the flow guide matrix PK / 3 is now formed by at least one separating hole field TL over the cross section of the separating region of pole body orifices 1 and associated ferromagnetic pole body wall parts 2 of a flow guide body.
- the main magnetic flux H runs, as mentioned, in the axial direction 1.0 of the pole body orifices 1 and thus parallel to the main flow path or the main flow direction z.
- the acting as a flow guide perforated perforated plate ZL divides it from the outer periphery of the separation region via feed zones v1, v2, v3 (compare (FIG 3) inflowing fluid flow A in the polar body orifices 1 inflowing partial flows p + d.
- On the outlet side at least one first collecting chamber SK1 communicates with the pole body orifices 1.
- the flow volume between the feed perforated plate ZL of the diamagnetic flow guide body and the separating perforated field TL of the pole body wall parts 3 serves as a second collecting chamber SK2.
- the first manifold SK1 is connected to a manifold v4 (FIG 3), and the second manifold SK2 is connected to the other manifold v5, v6.
- the first manifolds v4 are then connected to the first main manifold 60 and the second manifolds v5, v6 are connected to the second main manifold 70 as part of the combination of a plurality of separating pipes TR according to FIG. communicate with these main lines.
- the polar body orifices 1 and wall parts 3 of the respective separating perforated field TL are formed by a perforated plate-like fine structure with hollow-cone-shaped, projecting nozzles PK in the perforated area and the field line compression in the area of the nozzle orifices 1 local Gradient fields H1 result which exert attractive forces on paramagnetic particles flowing in the direction of the nozzle axis 1.0, see arrows F m , and repulsive forces on correspondingly flowing diamagnetic particles d, so that the core branch flow p entering paramagnetic through the nozzles PK or polar body Particles is enriched, on the other hand, the other or second branch stream d flowing past the nozzles PK is depleted of paramagnetic particles and enriched on diamagnetic particles.
- the boundary edges 1.1 of the pole body or nozzle orifices 1 are, as shown, rounded, which is favorable in relation to the field line and the flow resistance and thus improves the degree of separation.
- the feed openings 4 of the feed perforated plate ZL are to the Pole body mouths 1 of the separating perforated field TL are each arranged coaxially.
- a perforated sheet-like fine structure is provided for the pole body orifices 1 and the pole body wall parts 3 of the flow guide matrix PK / 3, each in pairs with a plane-parallel spaced apart (distance a2) and congruent arrangement of the two paired perforated sheets 3-3, the space between the paired perforated plates 3-3 serve as a collecting chamber SK1 of the first branch flows p and the space lying outside the perforated plates and adjacent to the feed perforated fields ZL serves as a second collecting chamber SK2 for the second branch flows d.
- the flow guide body for the feed perforated field ZL is also designed as a perforated plate-like fine structure, specifically with a spaced plane-parallel spacing (distance a1) and congruent arrangement of the two paired perforated plates 5-5, the space between the paired perforated plates 5-5. 5 serves as feed zone A0.
- a separating effect can already be achieved if a feed perforated field ZL with a single perforated plate 5 is assigned to a separating perforated field TL with a single perforated plate 3 with pole bodies PK on its pole body side.
- the separation module should be understood to mean the smallest, satisfactorily functioning basic unit MO1, which is arranged axially in the main flow direction z in the context of a separation tube TR.
- Each of these separating modules MO1 consists of a perforated plate pair 3-3 for the flow guide matrix PK / 3 and a perforated plate 5 for the feed perforated fields ZL, which is arranged on both sides of this perforated plate pair at a distance a3 in mirror image.
- modules M01 are stacked at intervals a1 such that the feed-in zones A0 are formed by the perforated plates 5 of the feed perforated fields ZL of the successive modules which are adjacent to one another.
- the separation module MO2 can also be regarded as the smallest module unit that repeats itself several times or repeatedly in the stacking direction, each of which be standing from a perforated plate pair 5-5 for the feed zones A0 and one perforated plate 5 arranged on both sides of this perforated plate pair at a distance a3 for the separating perforated fields TL.
- modules MO2 are stacked analogously to the modules MO1 at intervals a2 such that the first collecting chambers SK1 are formed by the perforated plates 3-3 of the perforated panels TL of the successive modules which are adjacent to one another.
- This stacked arrangement of the individual modules MO1 and MO2 results in the double-flow inflow in direction z and in direction -z and also a double-flow outflow in these two directions, which results in very good utilization of the volume of a separating tube TR (FIG. 3).
- a separating pipe TR preferably has a circular cross section, so that the perforated fields or perforated plates ZL, TL, as can be seen from FIG. 3, also have a circular plan.
- the separation modules MO1 or MO2 are stacked one above the other in the direction z and mechanically firmly connected to one another to form the separation tube TR (corresponding screw or welded connections are not shown in detail), the separation modules being separated from the tube wall 7 on their outer circumference are surrounded, this tube wall 7 being provided with the slots 8.1, 8.2, 8.3, as already explained.
- the pole body orifices 1 ⁇ and wall parts 3 ⁇ of a separating perforated field TL are each formed by a perforated plate-like fine structure in such a way that the field line thinning in the perforated area results in local gradient fields H2, which cause repulsive forces and para-magnetic particles p flowing in the direction of the perforated axis 1.0 exert attractive forces on correspondingly flowing diamagnetic particles, as shown by arrows F symbolizes so that the core branch stream d flowing through the polar body orifices 1 ⁇ is enriched with diamagnetic particles, whereas the branch stream p flowing past the pole body orifices 1 ⁇ is enriched with diamag netic particles are depleted or enriched in paramagnetic particles.
- the separation modules analogous to FIG. 1 are designated here as MO1 ⁇ or MO2 ⁇ .
- a separating tube TR can then be constructed from these individual separating modules in a manner corresponding to the arrangement according to FIG. 3.
- the advantage of such a separating tube from the modules MO1 ⁇ or MO2 ⁇ is, in particular, that the production of the flow guide matrix PK / 3 ⁇ is cheaper than that of the flow guide matrix according to FIG. 1, because only the remaining parts of a ferromagnetic perforated plate serve as the polar body PK ⁇ and special nozzle bodies are not provided here.
- a single separation tube TR is shown in FIG. 3 if it is provided with a suitable housing for supplying the particle-laden fluid streams A and for discharging the two fractions M (enriched in paramagnetic particles p) and NM (enriched in diamagnetic particles), already functional, but more for laboratory or experimental use.
- a plurality of separating pipes TR are combined in an axially parallel arrangement to form a separating pipe field and together with a container 100 surrounding the separating pipe field, which has at least one common main feed line 11 on the top side and first and bottom side has second main manifolds 60, 70, is combined to form a separating canister TK.
- FIGS. 5 to 7 are almost identical except for the fact that the main feed line 11 in FIG. 5 is connected centrally to the separating canister, but according to FIG. 6 is eccentric to its axis of rotation. 5 to 7, a high-performance solenoid or magnet MM is not shown; it is understood that such a high-performance magnet, arranged separating canister, also around a single one Separating canister according to FIGS. 5 to 7 can be arranged around so that its field lines enforce the multiple arrangement of the separating pipes TR inside the separating canister TK essentially in the axial direction.
- the separating pipes TR are arranged in a hexagonal grid and that the gusset alleys remaining free between these separating pipes are divided into feed or collecting lines 20 by the bulkheads 9, the feed lines being v 1 to through the line volumes v3 are formed and the first collecting lines through the line volumes v4 and the second collecting lines through the line volumes v5, v6 (see FIG 3).
- the loaded fluid flow A is via the main feed line 11 on the cover side of a prechamber 12 of the separating canister TK and from there via feed openings 10.1 provided in a correspondingly perforated flow guide plate 10, the outline of which corresponds to the cross section of the gusset spaces 20 between the separating pipes TR and bulkheads 9, all feed lines v1, v2, v3 fed in parallel.
