Abstract

In a magnetic cyclone dust separator the materials to be separated are exposed in a cyclone housing (1) to a stationary magnetic field generated by a superconductive exciting winding and to a rotating air stream. It is thus possible to separate with great precision dusts of different materials having differing susceptibilities and a grain size of less than 50 ν.

Description

MAGN--TI SCHER _T_T_LCrN-SCΗEIDER MAGN - TI SCHER _T_T_LCrN-SCΗEIDER
Die Erfindung betrifft einen magnetischen Zyklon-Schei¬ der, bestehend aus einem rotationssymmetrischen Zyklon¬ gehäuse mit trichterförmigem Abscheideraum, einem von oben in das Zyklongehäuse hineinreichenden Tauchrohr, einem an die Unterseite des Abscheideraumes anschließen¬ den und zu einem Staubsammelbehälter führenden Scheider¬ ohr sowie einem im oberen Teil des Zyklongehäuses tan- gential angeordneten Einblasrohr, zur Trennung von Stäuben mit unterschiedlicher Suszeptibilität.The invention relates to a magnetic cyclone separator, consisting of a rotationally symmetrical cyclone housing with a funnel-shaped separating space, an immersion tube extending into the cyclone housing from above, a separating ear connecting to the underside of the separating space and leading to a dust collecting container, and one In the upper part of the cyclone housing, there is a blowing tube arranged tangentially, for the separation of dusts with different susceptibility.
Seit langem sind sowohl Fliehkraft- als auch Magnet- scheider bekannt, die beide auch als Zyklone bezeichnet werde .Centrifugal and magnetic separators, both of which are also known as cyclones, have been known for a long time.
Fliehkraftscheider werden hauptsächlich zur Entstaubung und Reinigung der Luft bei Feuerungen für feste Brenn¬ stoffe, aber auch zur Reinigung der Kühlluft für elek¬ trische Maschinen verwendet. Wie schon aus der Benennung hervorgeht, beruht ihr Funktionsprinzip auf der Wirkung der Fliehkraft, welche auf die Staubteilchen einwirkt und ihr Ausscheiden aus dem zu reinigendem Luftstrom bewerk¬ stelligt.Centrifugal separators are mainly used for dedusting and cleaning the air in furnaces for solid fuels, but also for cleaning the cooling air for electrical machines. As can already be seen from the designation, their functional principle is based on the effect of centrifugal force, which acts on the dust particles and causes them to be separated from the air stream to be cleaned.
Magnetscheider hingegen werden zur Trennung von Stäuben mit unterschiedlicher Suszeptibilität bzw. für die Trennung metallischer von nichtmetallischen Stäuben eingesetzt. Ihre Wirkungsweise ergibt sich aus der von elektromagnetischen Feldern auf das Trenngut ausgeübten Scheidekraft. Die heute industriell verwendeten Magnet- scheider sind im allgemeinen gut geeignet, Materialien mit ferromagnetischen oder stark paramagnetischen Eigen¬ schaften von anderen Materialien mit diamagnetischen oder schwach paramagnetischen Eigenschaften zu trennen. Eine Trennung von Materialien mit geringen Unterschieden in ihren paramagnetischen Eigenschaften gelingt nur in einigen für Laboratoriumszwecke geeigneten Magnetschei- dern.Magnetic separators, on the other hand, are used to separate dusts with different susceptibility or to separate metallic from non-metallic dusts. Their mode of operation results from the cutting force exerted on the material to be separated by electromagnetic fields. The magnetic separators used industrially today are generally well suited to separating materials with ferromagnetic or strongly paramagnetic properties from other materials with diamagnetic or weakly paramagnetic properties. A separation of materials with small differences in their paramagnetic properties is only possible in some magnetic separators suitable for laboratory purposes.
Sowohl die Fliehkraft- als auch die Magnetscheider haben 5 in den letzten Jahren einen hohen Reifegrad erreicht. Es gibt jedoch nach wie vor kein System, mit dem es möglich ist, eine trockene Trennung von Stäuben mit einer klein¬ eren Korngröße als 50 u durchzuführen.Both the centrifugal and magnetic separators have reached a high level of maturity in the past 5 years. However, there is still no system with which it is possible to carry out a dry separation of dusts with a grain size smaller than 50 u.
0 In der Publikation EP-A2 0 110 674 ist ein Separations¬ prozeß beschrieben, der nicht auf einer besonders ausge¬ bildeten Strömungsform beruht, wie sie in den bekannten Zyklonen entsteht. Der in dieser Publikation vorgeschla¬ gene magnetische Scheideprozeß ist unabhängig von den in 5 der beschriebenen Separationsanlage herrschenden Ström¬ ungsverhältnissen.The publication EP-A2 0 110 674 describes a separation process which is not based on a specially designed flow form, such as is produced in the known cyclones. The magnetic separation process proposed in this publication is independent of the flow conditions prevailing in FIG. 5 of the separation system described.
Der Nachteil dieses Separationsprozesses besteht darin, daß es damit nicht möglich ist, das Scheidegut im 0 Trockenverfahren zu trennen. Soll das Scheidegut wieder¬ verwertet werden, so ist ein hoher Energieaufwand zum Trockenen erforderlich.The disadvantage of this separation process is that it is thus not possible to separate the Scheidegut in 0 dry process. If the material to be separated is to be recycled, a high expenditure of energy for drying is required.
Die GB-PS 2 148 746 befaßt sich mit einem Scheideprozeß, 5 der auf der kombinierten Wirkung eines bekannten magne¬ tischen Matrixscheiders mit einem bekannten elektrosta¬ tischen Filter beruht. Hervorgerufen wird dieser Scheide¬ prozeß durch die besondere Anordnung der magnetischen Matrix in einem magnetischen und einem elektrischen Feld.GB-PS 2 148 746 is concerned with a separating process, 5 which is based on the combined effect of a known magnetic matrix separator with a known electrostatic filter. This Scheide¬ process is caused by the special arrangement of the magnetic matrix in a magnetic and an electric field.

Auch dieses Verfahrens ist nachteilig, weil es nur für Naßtrennung anwendbar ist. Aus diesem Grund ist in jenen Fällen, in denen das Scheidegut wiederverwertet werden soll, einer hoher Energieaufwand nötig, um dieses ge- tt: trennte Scheidegut zu trocknen. In der DE-OS 33 04 863 wird ein Scheideprozeß beschrie¬ ben, bei dem das Scheidegut an einem Magneten vorbeige¬ führt wird. Dabei werden im Scheidegut befindliche, magnetische Verunreinigungen von dem Magneten angezogen 5 und festgehalten.This method is also disadvantageous because it can only be used for wet separation. For this reason, in those cases in which the material to be recycled is to be recycled, a large amount of energy is required in order to dry it: separated material. DE-OS 33 04 863 describes a cutting process in which the material to be separated is guided past a magnet. Magnetic impurities in the material to be separated are attracted 5 and held by the magnet.
Mit diesem Verfahren ist es nicht möglich, die Separa¬ tionswirkung des Zyklons so zu beeinflussen, daß die magnetischen Teile des Scheidegutes nicht, die unmagneti- 0 sehen Teile hingegen schon abgeschieden werden.With this method it is not possible, the Separa¬ tion effect of the cyclone to affect so that the magnetic parts of the sheath material, the unmagneti- 0 see parts will not, however, been deposited.
Die Aufgabe der Erfindung besteht darin, einen Zyklon zu schaffen, der Stäube unterschiedlicher Materialien und unterschiedlicher Suszeptibilität, deren Korngröße " weniger als 50 u beträgt, trennt.The object of the invention is to create a cyclone which separates dusts of different materials and different susceptibility, the grain size of which is "less than 50 u.
Die Aufgabe wird durch die Erfindung gelöst. Diese ist dadurch gekennzeichnet, daß im Zyklongehäuse ein Trenngut einem mit einer supraleitenden Erregerwicklung erzeugten, 0 stationären Magnetfeld und einer Luftrotation ausgesetzt ist.The object is achieved by the invention. This is characterized in that a signal generated in the cyclone housing a substance to be separated with a superconducting excitation winding, 0 stationary magnetic field and a rotation air is exposed.
Mit der Erfindung ist es möglich, eine Scheidung von Stäuben unterschiedlicher Materialien sowie unterschied- 5 licher Suszeptibilität und einer kleineren-Korngröße als 50 μ mit großer Trennschärfe durchzuführen.With the invention it is possible to carry out a separation of dusts of different materials as well as different susceptibility and a grain size smaller than 50 μ with high selectivity.
In einer Ausgestaltung der Erfindung ist die Außenwand des in das Zyklongehäuse ragenden Teiles des Tauchrohres als magnetfeiderzeugendes System ausgeführt. Dadurch wird die Scheidekraftwirkung auf die zu trennenden Teilchen vergrößert und eine Erhöhung der Trennschärfe bewirkt.In one embodiment of the invention, the outer wall of the part of the dip tube projecting into the cyclone housing is designed as a magnetic field generating system. This increases the effect of the cutting force on the particles to be separated and increases the selectivity.
In einer Weiterführung der Erfindung sind im Einblasrohr ' gekrümmte, drallerzeugende Leitbleche angeordnet. Dies ist vorteilhaft, weil dadurch alle eingeblasenen Stäubeteile schneller mit dem magnetfelderzeugenden System in Berührung kommen, woraus sich eine Erhöhung des Durchsatzes ergibt.In a further development of the invention, curved, swirl-generating guide plates are arranged in the injection tube. This is advantageous because this means that all the blown-in dust parts come into contact with the magnetic field-generating system more quickly, which results in an increase in throughput.
An Hand eines Ausführungsbeispieles soll nun die Erfin¬ dung näher erläutert werden. In der Fig. ist ein rota¬ tionssymmetrischer magnetischer Zyklon-Scheider mit seiner Rotationsache 6 im Schnitt dargestellt. Das Zyklongehäuse 1 ist in der Form eines flachen Kegel¬ stumpfes ausgebildet, dessen Erzeugende vom Zy¬ klonmantel 7 gebildet wird. An die Grundfläche des kegelstumpfförmigen Zyklongehäuses 1 schließt ein trich¬ terförmiger Abscheideraum 9 an, von welchem ein Scheide-" röhr 3 zu einem in der Fig. nicht dargestellten Staubsam¬ melbehälter führt. An der Übergangsstelle vom Abscheide¬ raum 9 zum Scheiderohr 3 ist eine Zellenradschleuse zum Entnehmen von Material in einem kontinuierlichen Betrieb angeordnet.Ein Einblasrohr 4 ist tangential im oberen Teil des Zyklongehäuses 1 angeordnet. Ein Tauchrohr 2 führt, von oben außen kommend, durch den das Zyklongehäu¬ se I abschließenden Zyklondeckel 8 weit in das Zyklonge¬ häuse hinein. Eine Erregerwicklung 5 ist an der Außen¬ seite des unteren Teiles des Tauchrohres 2 angebracht.The invention will now be explained in more detail using an exemplary embodiment. A rotationally symmetrical magnetic cyclone separator with its rotation axis 6 is shown in section in the figure. The cyclone housing 1 is designed in the form of a flat truncated cone, the generatrix of which is formed by the cyclone jacket 7. At the base of the frusto-conical cyclone body 1 includes a trich¬ terförmiger separation chamber 9, from which a separation works "tube 3 to a not shown in FIG. Staubsam¬ to leads melbehälter. The transition point from Abscheide¬ space 9 to the separator ear 3 is a A rotary feeder for removing material is arranged in a continuous operation.An injection tube 4 is arranged tangentially in the upper part of the cyclone housing 1. A dip tube 2, coming from outside on the outside, leads through the cyclone cover 8 which closes the cyclone housing I far into the cyclone housing An excitation winding 5 is attached to the outside of the lower part of the dip tube 2.
Im Prinzip wird mittels eines in der Fig. nicht darge¬ stellten-Gebläses das aus magnetisierbaren und nicht magnetisierbaren Teilchen bestehende Trenngut durch das Blasrohr 4 in das Zyklongehäuse 1 eingeblasen. Die Absetzung der magnetisierbaren Teilchen erfolgt in denIn principle, the separating material consisting of magnetizable and non-magnetizable particles is blown through the blow pipe 4 into the cyclone housing 1 by means of a blower (not shown in the figure). The magnetizable particles are deposited in the
Abscheideraum 9, während der Luftstrom, zusammen mit den magnetisierbaren Teilchen, durch das Tauchrohr 2 entwei¬ chen kann.Separation chamber 9, while the air flow, together with the magnetizable particles, can escape through the immersion tube 2.
Rotiert die durch das Blasrohr 4, zusammen mit dem Trenngut, in das Zyklongehäuse 1 eingeblasene Luft beispielsweise im Uhrzeigersinn, so wird dadurch die Zyklonrotation der magnetisierbaren Teilchen reduziert, wodurch sich auch der Einfluß der Fliehkraft auf diese Teilchen verringert. Gleichzeitig werden die magneti¬ sierbaren Teilchen vom magnetfelderzeugenden System - zentripetal angezogen und gelangen dadurch aus demIf the air blown into the cyclone housing 1, together with the material to be separated, rotates clockwise, for example, then the Cyclone rotation of the magnetizable particles is reduced, which also reduces the influence of centrifugal force on these particles. At the same time, the magnetisable particles are attracted by the magnetic field-generating system - centripetal and thereby get out of the
Luftströmungsbereich. Ein Absetzen der magnetisierbaren Teilchen im strömungsberuhigten Teil des Zyklongehäuses 1 ist damit nicht mehr möglich.Air flow area. It is no longer possible to deposit the magnetizable particles in the flow-reduced part of the cyclone housing 1.
Zu gleicher Zeit wird der Zyklonluftstrom durch dieAt the same time, the cyclone airflow through the
Verlustwärme des magnetfelderzeugenden Systems erwärmt, wodurch ein Trocknungseffekt des Trenngutes zustande kommt, der die Adhäsionskräfte der Teilchen aneinander reduziert.Loss heat of the magnetic field generating system is heated, which results in a drying effect of the material to be separated, which reduces the adhesive forces of the particles to one another.
Dieselbe Wirkung besteht selbstverständlich auch dann, wenn die durch das Blasrohr 4, zusammen mit dem Trenngut, in das Zyklongehäuse 1 eingeblasene Luft im Gegenuhrzei¬ gersinn rotiert.The same effect also exists, of course, if the air blown into the cyclone housing 1 together with the material to be separated rotates counterclockwise.
Das aus magnetisierbaren und nicht magnetisierbaren Teilchen bestehende Trenngut wird durch das Einblas- rohr 4 in das Zyklongehäuse 1 eingeblasen. Dadurch kommen sowohl die magnetisierbaren als auch die nicht magneti- sierbaren- Teilchen mit dem magnetfeiderzeugenden System im Zyklongehäuse 1 in Berührung. Das magnetfeiderzeugende System wirkt nur auf die magnetisierbaren Teilchen derart, daß ihre Rotationsbewegung durch die Zyklonwir¬ kung gegenüber der Rotationsbewegung der nicht magneti- sierbaren Teilchen verlangsamt wird.The material to be separated, which consists of magnetizable and non-magnetizable particles, is blown into the cyclone housing 1 through the blow-in tube 4. As a result, both the magnetizable and the non-magnetizable particles come into contact with the magnetic field generating system in the cyclone housing 1. The magnetic field generating system acts only on the magnetizable particles in such a way that their rotational movement is slowed down by the cyclone effect compared to the rotational movement of the non-magnetizable particles.
Die Zyklonwirkung ist eine durch die Fliehkraft zustan¬ degekommene Spiralbewegung entlang der Außenwand des Zyklonbehälters 1, welche bewirkt, daß die Luftströmung alle Teilchen des Trenngutes in strömungsarme Bereiche des Zyklongehäuses 1 entläßt und nicht durch die Öffnung des Tauchrohres 2, durch das die eingeblasene Luftmenge abgezogen wird, mitreißen kann.The cyclone effect is a spiral movement, which is brought about by the centrifugal force, along the outer wall of the cyclone container 1, which causes the air flow to release all particles of the separating material into low-flow areas of the cyclone housing 1 and not through the opening of the immersion tube 2, through which the amount of air blown in is drawn off, can carry away.
Durch entsprechende Anordnung der Erregerwicklung 5 ist die Außenwand des in das Zyklongehäuse ragenden Teiles des Tauchrohres 2 als magnetfelderzeugendes System derart ausgeführt, daß das Magnetfeld im Außenbereich des Tauchrohres 2 erzeugt wird und sich somit im Einblasbe- reich des Trenngutes befindet.By appropriately arranging the excitation winding 5, the outer wall of the part of the immersion tube 2 projecting into the cyclone housing is designed as a magnetic field-generating system such that the magnetic field is generated in the outer region of the immersion tube 2 and is thus located in the blowing area of the material to be separated.
Die magnetisierbaren Teilchen werden durch das Magnetfeld derart beeinflußt, daß die Zyklonwirkung nicht in glei¬ cher Weise wie bei den nicht magnetisierbaren Teilchen zustande kommt. Die Fliehkraftwirkung auf die magneti- - sierbaren Teilchen ist somit geringer, ebenso ihr Flug¬ bahnabstand von dem als magnetfelderzeugendes System ausgebildeten Tauchrohr 2. Auf diese Weise werden die magnetisierbaren Teilchen vom Luftstrom durch die Öffnung des Tauchrohres 2 abgezogen und können in einem weiteren, gewöhnlichen Zyklon abgeschieden werden. The magnetizable particles are influenced by the magnetic field in such a way that the cyclone effect does not occur in the same way as with the non-magnetizable particles. The effect of centrifugal force on the magnetizable particles is thus less, as is their flight path distance from the dip tube 2 designed as a magnetic field-generating system. In this way, the magnetizable particles are drawn off from the air stream through the opening of the dip tube 2 and can be used in a further, conventional manner Cyclone to be separated.
