Description

Die Erfindung betrifft eine Leiteinrichtung einer Vorrichtung, insbesondere eines Fliehkraftabscheiders bzw. Zyklonabscheiders, zum Abtrennen wenigstens eines Stoffes aus einem gasförmigen oder flüssigen Medium unter der Wirkung von Zentrifugalkräften, wobei der Stoff ein höheres spezifisches Gewicht als das Medium aufweist, wobei die Leiteinrichtung wenigstens ein gekrümmtes Leitblech aufweist, dessen Radius von der Mittelachse der Leiteinrichtung in Drehrichtung des Mediums gesehen abnimmt, mit wenigstens einer Eintrittsöffnung für das großteils vom Stoff befreite Medium in die Leiteinrichtung, und mit einer Bodenplatte am in das Innere der Vorrichtung ragenden Ende der Leiteinrichtung.The invention relates to a guide device of a device, in particular a centrifugal separator or cyclone, for separating at least one substance from a gaseous or liquid medium under the action of centrifugal forces, wherein the substance has a higher specific gravity than the medium, wherein the guide at least one curved Has baffle whose radius decreases seen from the central axis of the guide in the direction of rotation of the medium, with at least one inlet for the largely freed from the medium medium in the guide, and with a bottom plate at the projecting into the interior of the device end of the guide.

Die Erfindung betrifft des weiteren ein Tauchrohr einer Vorrichtung, insbesondere eines Fliehkraftabscheiders bzw. Zyklonabscheiders, zum Abtrennen wenigstens eines Stoffes aus einem gasförmigen oder flüssigen Medium unter der Wirkung von Zentrifugalkräften, wobei der Stoff ein höheres spezifisches Gewicht als das Medium aufweist.The invention further relates to a dip tube of a device, in particular a centrifugal separator or cyclone separator, for separating at least one substance from a gaseous or liquid medium under the action of centrifugal forces, wherein the substance has a higher specific gravity than the medium.

Die Erfindung betrifft schließlich noch eine Vorrichtung, insbesondere einen Fliehkraftabscheider bzw. Zyklonabscheider, zum Abtrennen wenigstens eines Stoffes aus einem gasförmigen oder flüssigen Medium unter der Wirkung von Zentrifugalkräften, wobei der Stoff ein höheres spezifisches Gewicht als das Medium aufweist, mit einem Gehäuse, mit einer Einrichtung zum Erzeugen einer Drehbewegung des Gemenges aus Stoff und Medium in einer Trennkammer und mit einer Leiteinrichtung, durch die das Medium großteils vom Stoff befreit und anschließend aus der Trennkammer abgeführt wird.Finally, the invention relates to a device, in particular a centrifugal separator or cyclone separator, for separating at least one substance from a gaseous or liquid medium under the action of centrifugal forces, wherein the substance has a higher specific gravity than the medium, with a housing, with a Means for generating a rotational movement of the mixture of substance and medium in a separation chamber and with a guide, by which the medium largely freed from the substance and then discharged from the separation chamber.

Derartige Einrichtungen (Fliehkraftabscheider bzw. Zyklonabscheider) sind aus der WO 92/10300 A1 bekannt. Insbesondere ist es aus der WO 92/10300 A1 bekannt, am Ende der Leiteinrichtung eine Bodenplatte anzuordnen, die verhindert, dass stirnseitig Medium in die Leiteinrichtung eintritt. Auf der anderen Seite behindert diese Bodenplatte aber ein ungestörtes Anströmen der Leiteinrichtung bzw. Einströmen des Mediums in die Leiteinrichtung in Form einer Spiralströmung im Bereich des äußeren Umfangs der Bodenplatte, sodass die bekannte Leiteinrichtung nicht ganz zufriedenstellend arbeitet.Such devices (centrifugal separator or cyclone) are from the WO 92/10300 A1 known. In particular, it is from the WO 92/10300 A1 known at the end of the guide to arrange a bottom plate, which prevents the front side medium enters the guide. On the other hand hinders this bottom plate but an undisturbed influx of the guide or inflow of the medium into the guide in the form of a spiral flow in Area of the outer circumference of the bottom plate, so that the known guide does not work quite satisfactory.

Der Erfindung liegt daher die Aufgabe zu Grunde, die bekannte Leiteinrichtung in dieser Hinsicht zu verbessern.The invention is therefore based on the object to improve the known guide in this regard.

Gelöst wird diese Aufgabe mit einer Leiteinrichtung mit den Merkmalen des Anspruches 1.This object is achieved with a guide device having the features of claim 1.

Bei der Erfindung ist die Bodenplatte nur in jenem Bereich vorgesehen, in dem die An- bzw. Einströmung in die Leiteinrichtung unerwünscht ist, wogegen die Bodenplatte im Bereich der Eintrittsöffnung eine Ausnehmung aufweist, sodass die Strömung des Mediums in diesem Bereich nicht behindert wird.In the invention, the bottom plate is provided only in that area in which the arrival or inflow into the guide is undesirable, whereas the bottom plate in the region of the inlet opening has a recess, so that the flow of the medium is not hindered in this area.

Bei der Erfindung können zwei oder mehr Leitbleche und eine entsprechende Anzahl von Ausnehmungen in der Bodenplatte vorgesehen sein, die sich im Bereich der zwischen jeweils zwei benachbarten Leitblechen gebildeten Eintrittsöffnungen befinden. Die Anzahl der Leitbleche richtet sich nach der gewünschten Leistung der Vorrichtung sowie nach der Art bzw. Beschaffenheit von Stoff und Medium sowie der gewünschten Reinheit des gereinigten Mediums.In the invention, two or more baffles and a corresponding number of recesses may be provided in the bottom plate, which are located in the region of the inlet openings formed between each two adjacent baffles. The number of baffles depends on the desired performance of the device as well as the nature of the substance and medium and the desired purity of the purified medium.

Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass ein Abschnitt der Kontur der Ausnehmung in der Bodenplatte von einem Eintrittsrand gebildet wird, der parallel zum anschließenden Leitblech liegt. Die Kontur der Ausnehmung folgt daher in diesem Bereich der Form des Leitbleches wodurch die Strömung des Mediums hier nicht von der Bodenplatte behindert wird.A preferred embodiment of the invention is characterized in that a portion of the contour of the recess in the bottom plate is formed by an inlet edge which is parallel to the subsequent baffle. The contour of the recess therefore follows in this area the shape of the baffle whereby the flow of the medium is not hindered by the bottom plate here.

In einer vorteilhaften Weiterbildung der Erfindung ist diese dadurch gekennzeichnet, das ein Abschnitt der Kontur der Ausnehmung in der Bodenplatte von einer Bodenkante gebildet wird, die von einer Anströmkante eines Leitbleches zum Inneren des Leitapparates verläuft. Mit dieser Bodenkante kann bestimmt werden, wie weit sich die Ausnehmung im Bereich der Eintrittsöffnung in Drehrichtung des Mediums erstreckt.In an advantageous embodiment of the invention, this is characterized in that a portion of the contour of the recess in the bottom plate is formed by a bottom edge extending from a leading edge of a baffle to the interior of the nozzle. With this bottom edge can be determined how far the recess in the region of the inlet opening in the direction of rotation of the medium extends.

Die von einer Anströmkante eines Leitbleches zum Inneren des Leitapparates verlaufende Kante kann bei einer Ausführungsform der Erfindung im wesentlichen gerade sein.The edge extending from a leading edge of a baffle to the interior of the nozzle may be substantially straight in one embodiment of the invention.

Durch die Ausnehmung in der Bodenplatte wird das An- und Einströmverhalten des Mediums verbessert, da das Medium beim Eintritt in die Leiteinrichtung nicht nur eine Strömungskomponente in Umfangs- bzw. Drehrichtung sondern auch in Achsrichtung aufweist.By the recess in the bottom plate, the arrival and inflow of the medium is improved, since the medium has not only a flow component in the circumferential or rotational direction but also in the axial direction when entering the guide.

Um das Anströmverhalten weiter zu verbessern, kann in einer bevorzugten Ausführungsform der Erfindung vorgesehen sein, dass die Anströmkante eines Leitblechs wenigstens im der Bodenplatte benachbarten Abschnitt in Drehrichtung des Mediums geneigt verläuft. Der Anströmkante kann somit eine Ausrichtung gegeben werden, die etwa im rechten Winkel zur Strömungsrichtung des Mediums liegt.In order to further improve the flow behavior, it can be provided in a preferred embodiment of the invention, that the leading edge of a baffle extends inclined at least in the adjacent portion in the bottom plate in the direction of rotation of the medium. The leading edge can thus be given an orientation which is approximately at right angles to the flow direction of the medium.

Wenn die nach innen verlaufende Kante der Ausnehmung von der Anströmkante des Leitbleches wegführt, wird somit insgesamt eine vergrößerte Eintrittsöffnung für das Medium in die Leiteinrichtung geschaffen, welche den axialen und tangentialen Eintritt des Mediums verbessert und somit zu geringeren Leistungsverlusten des Zyklonabscheiders führt.When the inwardly extending edge of the recess leads away from the leading edge of the baffle, thus an overall enlarged inlet opening for the medium is created in the guide, which improves the axial and tangential entry of the medium and thus leads to lower power losses of the cyclone.

In der Regel sind Leiteinrichtungen wie die erfindungsgemäße Leiteinrichtung an einem Tauchrohr angeordnet, das in eine Trennvorrichtung ragt, in welcher der Stoff aus einem gasförmigen oder flüssigen Medium abgetrennt wird.As a rule, guide devices, such as the guide device according to the invention, are arranged on a dip tube which protrudes into a separating device in which the substance is separated from a gaseous or liquid medium.

Gemäß der Erfindung ist daher das eingangs genannte, gattungsgemäße Tauchrohr dadurch gekennzeichnet, dass am in das Innere der Vorrichtung ragenden Ende des Tauchrohres eine Leiteinrichtung nach einem der Ansprüche 1 bis 11 angeordnet ist.According to the invention, therefore, the aforementioned generic immersion tube is characterized in that on the projecting into the interior of the device end of the dip tube, a guide device according to one of claims 1 to 11 is arranged.

Die erfindungsgemäße Aufgabe wird schließlich noch gelöst mit einer gattungsgemäßen Vorrichtung, die dadurch gekennzeichnet ist, dass sie eine Leiteinrichtung aufweist, die nach einem der Ansprüche 1 bis 11 ausgebildet ist.The object of the invention is finally achieved with a generic device, which is characterized in that it comprises a guide, which is designed according to one of claims 1 to 11.

Weitere bevorzugte Ausführungsformen der Erfindung sind Gegenstand der übrigen Unteransprüche.Further preferred embodiments of the invention are the subject of the remaining dependent claims.

Nachfolgend wird eine bevorzugte Ausführungsform der Erfindung unter Bezugnahme auf die angeschlossene Zeichnung beschrieben. Es zeigt Fig. 1 eine perspektivische Ansicht auf eine erfindungsgemäße Ausführungsform einer Leiteinrichtung und Fig. 2 eine perspektivische Ansicht auf die Leiteinrichtung aus einem anderen Winkel.Hereinafter, a preferred embodiment of the invention will be described with reference to the accompanying drawings. 1 shows a perspective view of an embodiment of a guide device according to the invention, and FIG. 2 shows a perspective view of the guide device from another angle.

Die Fig. 1 und 2 zeigen eine Leiteinrichtung, die im wesentlichen aus einer zylinderförmigen Wand 1 im oberen Bereich, vier Leitblechen 2 und einer Bodenplatte 3 besteht. Die vier Leitbleche 2 sind alle gleich aufgeführt und weisen eine teilkegelförmige Gestalt auf. Das heißt, dass ihr Krümmungsradius im Bereich der Bodenplatte 3 kleiner ist als im gegenüber liegenden Bereich nahe der zylinderförmigen Wand 1 und dass sie sich um einen Winkel von etwa 100° bis 110° erstrecken. Die Krümmungsachse jedes Leitbleches 2 liegt parallel zur Mittelachse der Leiteinrichtung, die der Achse der zylinderförmigen Wand 1 entspricht.1 and 2 show a guide, which consists essentially of a cylindrical wall 1 in the upper region, four baffles 2 and a bottom plate 3. The four baffles 2 are all listed the same and have a part-conical shape. This means that their radius of curvature in the region of the bottom plate 3 is smaller than in the opposite region near the cylindrical wall 1 and that they extend at an angle of about 100 ° to 110 °. The axis of curvature of each baffle 2 is parallel to the central axis of the guide, which corresponds to the axis of the cylindrical wall 1.

Der innerhalb der Leiteinrichtung angeordnete Längsrand 4 der Leitbleche 2 liegt im wesentlichen in einer Ebene der Krümmungsachse des jeweiligen Leitblechs 2. Die außen und dem Längsrand 4 gegenüberliegende Anströmkante 5 weist in der in den Zeichnungen dargestellten Ausführungsform keinen geraden sondern einen abgewinkelten Verlauf auf. Der obere, der zylinderförmigen Wand 1 benachbarte Abschnitt 5a ist im wesentlichen parallel zur Krümmungsachse ausgerichtet, wogegen der untere, der Bodenplatte 3 benachbarte Abschnitt 5b in Drehrichtung des Mediums geneigt und in einem Winkel von etwa 90° zur Strömungsrichtung des Mediums ausgerichtet ist. Die Drehrichtung des Mediums ist in Fig. 1 durch den Pfeil 10 dargestellt.The arranged within the guide longitudinal edge 4 of the baffles 2 is located substantially in a plane of the axis of curvature of the respective baffle 2. The outside and the longitudinal edge 4 opposite leading edge 5 has no straight but angled course in the embodiment shown in the drawings. The upper, the cylindrical wall 1 adjacent portion 5a is aligned substantially parallel to the axis of curvature, whereas the lower, the bottom plate 3 adjacent portion 5b is inclined in the direction of rotation of the medium and aligned at an angle of about 90 ° to the flow direction of the medium. The direction of rotation of the medium is shown in Fig. 1 by the arrow 10.

Die zylinderförmige Wand 1 besteht aus einem zylindrischen Ring 6 und vier spitzen Ansätzen 7 an denen die Leitbleche 2 anschließen. Die Vorderkante 8 dieser Ansätze 7 bildet eine Verlängerung der Anströmkante 5a der Leitbleche 2. An die Hinterkante 9 der Ansätze 7 schließen die Leitbleche 2 an. Es ist ersichtlich, dass die Leitbleche 2 im Anschlussbereich 9 an die Ansätze 7 der zylindermantelförmigen Wand 1 nicht gekrümmt sind, da sich der Anschluss auf diese Weise technisch leichter herstellen lässt. Es ist daher tatsächlich nur der in Drehrichtung 10 dahinter liegende Bereich der Leitbleche 2 kegelförmig gekrümmt.The cylindrical wall 1 consists of a cylindrical ring. 6 and four pointed lugs 7 at which the baffles 2 connect. The front edge 8 of these projections 7 forms an extension of the leading edge 5a of the baffles 2. At the trailing edge 9 of the lugs 7 close the baffles 2. It can be seen that the baffles 2 are not curved in the connection region 9 to the lugs 7 of the cylinder jacket-shaped wall 1, since the connection can be produced in this way technically easier. It is therefore actually only in the direction of rotation 10 behind lying area of the baffles 2 conically curved.

Die Bodenplatte 3 sieht in gewisser Weise propellerartig aus, wobei zwischen Flügeln 11 Ausnehmungen 12 angeordnet sind. Begrenzt werden die Flügel 11 bzw. die Ausnehmungen 12 von einem Eintrittsrand 13 und einer Bodenkante 14. Der Eintrittsrand 13 hat eine gekrümmte Form, die dem anschließenden Rand der Leitbleche 2 entspricht. Die Bodenkante 14 ist gerade und führt von der unteren Ecke 17 der anschließenden Anströmkante 5b nach innen.The bottom plate 3 looks somewhat like a propeller, with 11 recesses 12 are arranged between wings. The wings 11 and the recesses 12 are bounded by an entry edge 13 and a bottom edge 14. The entry edge 13 has a curved shape which corresponds to the adjoining edge of the guide plates 2. The bottom edge 14 is straight and leads from the lower corner 17 of the adjoining leading edge 5b inwards.

Anstelle einer abgewinkelten Anströmkante 5 an den Leitblechen 2 könnte auch eine Anströmkante verwendet werden, die in Verlängerung der Anströmkante 9 an der zylinderförmigen Wand 1 gerade weiterführt. Denkbar und vorteilhafter wäre aber zum Beispiel eine Anströmkante an den Leitblechen 2, die mehr oder weniger gerade, d.h. ohne nennenswerte Krümmung, direkt von der Spitze 15 der Ansätze 7 in Strömungsrichtung 10 geneigt zur Ecke 17 an der Bodenplatte 3 verläuft.Instead of an angled leading edge 5 on the baffles 2 and a leading edge could be used, which just continues in extension of the leading edge 9 on the cylindrical wall 1. However, it would be conceivable and advantageous, for example, to have a leading edge on the baffles 2, which are more or less straight, i. without significant curvature, directly from the tip 15 of the lugs 7 in the flow direction 10 inclined to the corner 17 on the bottom plate 3 extends.

Durch die Ausnehmungen 12 in der Bodenplatte 3 kann die Eintrittsöffnung 16, die zwischen benachbarten Leitblechen 2 gebildet wird, nicht nur tangential angeströmt werden sondern auch mit einer achsialen Komponente durch die Ausnehmungen 12 in der Bodenplatte 3, was sich strömungstechnisch günstig auswirkt. Durch die zusätzliche Neigung der Anströmkante 5b etwa im rechten Winkel zur Strömungsrichtung kann das Anströmverhalten zusätzlich günstig beeinflusst werden.Through the recesses 12 in the bottom plate 3, the inlet opening 16, which is formed between adjacent baffles 2, not only tangential be flowed but also with an axial component through the recesses 12 in the bottom plate 3, which has a favorable flow. Due to the additional inclination of the leading edge 5b approximately at right angles to the flow direction, the flow behavior can be additionally favorably influenced.

Die erfindungsgemäße Leiteinrichtung kann wie im Stand der Technik üblich an einem in den Zeichnungen nicht dargestellten Tauchrohr befestigt werden, wozu die Öffnungen 18 in der zylinderförmigen Wand 1 dienen. Die Leiteinrichtung ist des weiteren in einem Fliehkraftabscheider bzw. Zyklonabscheider mit einem Gehäuse eingebaut, der eine Einrichtung zum Erzeugen einer Drehbewegung des Gemenges aus Stoff und Medium sowie eine Trennkammer aufweist, in welche die Leiteinrichtung ragt. Das großteils vom Stoff befreite Medium wird dann durch die Leiteinrichtung aus der Trennkammer abgesaugt und strömt axial aus der Leiteinrichtung ab. Da derartige Vorrichtungen im Stand der Technik, z.B. EP-A-398 864 , hinlänglich bekannt sind, wurden sie in der vorliegenden Anmeldung nicht näher dargestellt und beschrieben.The guide device according to the invention can be attached as usual in the prior art to a dip tube, not shown in the drawings, including the openings 18 in the cylindrical wall 1 serve. The guide is further incorporated in a centrifugal separator or cyclone separator with a housing having a means for generating a rotational movement of the mixture of material and medium and a separation chamber, in which protrudes the guide. The largely freed from the medium medium is then sucked through the guide from the separation chamber and flows axially from the guide. Since such devices in the prior art, eg EP-A-398 864 , are well known, they were not shown and described in detail in the present application.
