Definitions
- the present invention relates to a traveling field ⁇ reactor and to a method for separating magnetizable particles from a liquid using the traveling wave reactor.
- the traveling-field reactor comprises a tubular reactor, on the outer circumference of which at least one magnet for generating a traveling field is arranged and whose interior is permeable by the liquid. In the interior of the tubular reactor, a displacement body is arranged.
- Magnetizable particles are also understood to mean magnetic particles which are already magnetized. Magnetizable particles are formed during ore processing, for example, when the iron ore rock is ground to a small size. To separate the metal to be recovered, eg magnetite (FesC), from the remaining material, eg sand, the ground stone is mixed with water or oil. In Wanderfeldre ⁇ actuators then magnetizable particles are separated from the mixture, taking advantage of the magnetization and the directed movement of the particles in magnetic fields.
- FesC magnetite
- the ground stone is mixed with water or oil.
- Prefabricated magnetizable particles can also be used for threaded ⁇ NEN of compounds from ores by, for example, may ⁇ netisierbare particles chemically or physically activated functionalized be used.
- the components to be recovered in the ores can be bound to the particles chemically, eg via sulfidic bonds, or physically, eg via Coulomb interaction.
- magnetizable particles and trace substances can be separated from a solution, solids from a suspension or Liquids with different phases are separated from each other.
- the mixture Upon separation of the magnetizable particles from the liquid, the mixture is pumped through a tubular reactor or flows e.g. taking advantage of gravity through the reactor.
- the reactor is surrounded by electromagnetic coils or permanent magnets which generate a magnetic field inside the reactor. The magnetic field acts on the magnetizable particles in the liquid.
- the magnetisable particles are moved in the direction of the wall, ie the inner wall of the tubular reactor.
- the electromagnetic coils or permanent magnets generate a traveling field along the longitudinal direction of the tubular reactor, ie the magnetic field changes its amplitude in such a way that along the longitudinal direction or in the direction of the liquid flow, the magnetic field moves with its amplitude in time and in space. Due to the effect of the traveling field, the magnetizable particles moved to the wall are collected to form agglomerates and moved along the wall in the direction of the longitudinal axis of the reactor or with the flow.
- exhaust openings are arranged in the wall of which is controlled or regulated opened and resealed who can ⁇ . When the suction openings are open, the particles can be sucked out of the reactor. The remaining liquid ⁇ speed without or with highly depleted particle concentration is discharged or pumped out of the reactor via a pipe outlet of the tubular reactor.
- an annular separating diaphragm can be arranged in the region of the suction openings. This is arranged as a kind of pipe section with a smaller outer diameter in the tube of the tubular reactor with a larger inner diameter. Between the divider tube piece and the reactor tube, a gap is formed, which is sufficiently large around the Agglomerates of magnetizable particles along the wall in the region of the gap to be able to move through the gap. The gap is small enough to allow only the least amount of liquid to flow through the gap with the magnetizable particles moving along the wall.
- the remaining liquid which contains no magnetisable particles or at least a reduced concentration of mag ⁇ netisierbaren particles, flows through the inner region of the dividing orifice, which is completely encompassed by the annular dividing orifice, to the tube outlet of the tubular reactor.
- the magnetizable particles in the gap can be discharged or sucked directly via a gap output, or suction openings in the wall can be used to control the magnetized particles in the gap controlled or from ⁇ .
- the displacement body is, for example, cylindrical in the hollow cylinder or tubular reactor, preferably seen centrally in cross section, arranged.
- the liquid flows in the gap between the wall of the reactor and the displacement body and the flow cross-section is restricted from a circular to a round annular cross-section. Instead of rounds, other cross sections are also conceivable.
- the traveling-field reactor described above leads to an effective separation of magnetizable particles and liquid.
- a traveling-field reactor Depending on the geometry of the divider and depending on the flow and traveling field velocity, a
- a recyclable material stream, which comprises the magnetizable particles, is thus not obtained continuously, but quasi-continuously, pulsantly from the reactor.
- Object of the present invention is therefore to provide a traveling wave reactor for separating magnetizable particles from a liquid and a method for its use which prevent thickening or Verzähissueung and thus an improved separation of particles and fluid at a reduced cost and effort as well as Incr ⁇ ter Allow yield.

- the traveling-field reactor according to the invention for separating magnetisable particles from a liquid comprises a tubular reactor, at least one of which is provided on its outer circumference
- Magnet is arranged to generate a traveling field.
- the interior of the tubular reactor can be flowed through by the liquid and a displacement body is arranged in the interior.
- the displacement body is designed to introduce liquid into the interior of the tubular reactor.
- the liquid which is passed through the displacement body in the interior of the tubular reactor, leads to a dilution of the liquid with magnetizable Parti- no in the reactor.
- the liquid flow with magnetizable particles which is taken from the reactor or pumped off, be changed from pulsatile to more continuous flow.
- the dilution of the liquid with magnetizable particles can be done, for example, with pure water or pure oil, depending on whether the starting liquid contains magnetizable particles of water or oil.
- the dilute mixture can be fed to another reactor and the dilution leaves the mixture better liquid and easier to process and further concentrate or clean. With each successive pass through a traveling wave reactor tailing is removed and the concentration and purity of ge ⁇ desired value material particles or particles bound Recyclable material is increasing. Thus, the yield is to gain ⁇ increases the recovered substance.
- the dilution with fluid from the displacement body thus increases the processability of the valuable substance from the reac tor ⁇ , if repeated run, the improved viscous ⁇ sity of the liquid and reduced by the dilution of particle density increases, the particle mobility.
- better magnetizable particles can be moved to the wall in the magnetic field and thus better separated from the liquid by tailing.
- the better separation requires fewer passes to achieve desired particle concentration and tailing. This saves costs, effort and increases the yield.
- the displacement body may be formed as a pipeline.
- the pipeline can be flowed through by liquid and at one end of the pipeline in the interior of the tubular reactor, at least one opening for introducing the liquid can be arranged in the interior of the tubular reactor.
- Characterized an addition of the liquid ⁇ ness of the displacement body to the flow of the fluid with magnetisable particles in the tubular reactor in a spatial region is possible, in which the magnetizable particles are summarized already as agglomerates on the wall by the magnetic traveling field.

- a suction of the magnetized particles through suction openings in the wall of the reactor can be dispensed with.
- the technical complexity is reduced. Even if suction openings are used, only the residual liquid with magnetisable particles is sucked off and not the main stream of liquid, which in this case results in a better separation of the magnetizable particles from the liquid (main stream).

- the residual liquid with magnetizable particles can leave the reactor directly via the gap between the separation screen and the wall of the reactor or can be pumped out through openings in the wall without reconnecting to the main flow.
- the shape of a hollow cylinder of the divider diaphragm results in favorable flow conditions of the liquids in the region of the divider.
- the hollow cylindrical shape with a longitudinal axis paral ⁇ lel the flow direction of the liquid with magnetisierba ⁇ ren particles in front of the diaphragm provides a low flow resistance upon entry of the liquid in the region of the diaphragm, and thus enables a reduced pump power.
- the divider and the displacer may be formed of a homogeneous body. This leads to a particularly mechanically stable construction.
- a non-magnetic material is selected as the material for the displacement body and the separating diaphragm.
- a material e.g. Plastic used.
- the tubular reactor and / or the displacement body may be formed as a hollow cylinder, with a circular cross-sectional area. This results in a particularly simple structure and favorable flow conditions through the reactor without much flow resistance, high mechanical stability Sta ⁇ .
- the at least one opening may be arranged on a circumference. As a rule, instead of an opening, a multiplicity of openings are used in order to be able to introduce liquid over the support body in all regions of the gap between the wall of the reactor and the aperture.
- a favorable embodiment provides that six openings are arranged on the circumference, at the intersections of the circumference with a beam pair starting from the center of the circle, where ⁇ in the pair of beams each having an angle of 60 °, 120 °, 180 °, 240 ° and 300 ° includes.
- the openings are usually directly at the end of the columns.

- the first liquid can flow in a space between the displacement body and a wall of the tubular reactor in the interior of the tubular reactor along a
- Flow longitudinal axis of the tubular reactor and the second liquid can flow from the interior of the tubular displacement body via tubular webs at one end of the tubular displacement body to at least one opening, in particular to 6 nozzle-shaped openings in a dividing orifice between the displacement body and tubular reactor.

- openings may be arranged in the wall 10 of the tubular reactor 2, which can be opened when passing through an agglomerate 14 and thus can selectively extract the agglomerates 14 ,
- the residual liquid 5 with magnetisable particles Due to the increased proportion of magnetizable particles, the residual liquid 5 with magnetisable particles, which is taken from the reactor 2 through openings or an exit in the gap between separating aperture 9 and tubular reactor 2, has a very viscous or high viscosity. This can clog openings or gaps and lead to problems in further processing.
- a second liquid in particular a pure liquid such as pure water or oil, is pumped, introduced or injected into the gap between the dividing panel 9 and the wall 10 of the tubular reactor 2. This leads to a dilution of the residual liquid 5 with agglomerated magnetizable particles 14, prevents clogging of the exits or removal openings, and facilitates further processing of the magnetizable particles.
- the second liquid for dilution can be easily fed via the displacer, since feeding through openings in the wall 10 of the tubular reactor 2 would lead to problems in the movement of the magnetizable particles on the wall 10.

Between the webs 11 is space over which the main part of the liquid can be discharged without or with a greatly reduced concentration of magnetizable particles or flow through the interior 4 of the annular separation panel 9 or can flow.
- the gap is formed, which results in an indoor ⁇ space 4 and a gap through which the agglomerated magnetizable particles 14, which are moved to the wall 10 along the reactor 2 removed and in which second liquid 12 is added for dilution.
- the second liquid 12 is supplied via the tube-shaped displacement body 6 via fluidically connected thereto tubular webs 11, the openings 8 in the separating diaphragm 9, which may be formed in the shape of nozzles from ⁇ . Via the openings 8, the second liquid 12 is brought into the gap between the wall 10 of the tubular reactor 2 and separator 9.

This results in a total flow of the liquid 5, 12, which allows a good mixing of the liquids 5 and 12, for example by vortex formation.
- there is a partial flow in the gap which counteracts the entry of liquid 5 with tailing, whereby an improvement in the separation of magnetizable particles from tailing is achieved.
- the movement of the magnetizable particles is affected only partially or not at all by the flow, since it is essentially determined by the traveling field as a function of the gap width.
- Embodiments can also be combined with each other.
- a number of different substances are possible as liquids and particles.
