Definitions
- the invention relates to a centrifugal separator for the separation of at least one substance from a liquid or gaseous medium.
- the US 2 731 147 A and the AT 392 924 B each show a generic centrifugal separator.
- the centrifugal separator has a cavity which extends at least in a substantial portion of its height approximately circularly symmetrical about a vertical axis.
- a supply tube opens into the upper part of the cavity, which is arranged and aligned tangentially to the circumferential direction of the cavity in the region of the orifice.
- the removal of treated in the cavity medium via two tubes which end vertically from below and from above, coaxial with the axis of the cavity, with facing, open end faces in the cavity.
- the tubes have smaller outer diameter than the cavity.
- the open ends of the end faces are spaced from both the bottom and the top surface of the cavity.
- Medium which flows in through the feed tube, forms in the cavity a flow vortex in which substances which are specifically heavier than the medium to be treated, are forced radially outward by centrifugal force and, according to gravity, sink to the bottom of the cavity without entering the tubes which serve for the removal of treated medium. From the bottom of the cavity, these substances can be discharged continuously or discontinuously through an outlet provided for this purpose.
- the discussed construction according to the US 2 731 147 A and the AT 392 924 B advantageous, because it has a better separation effect, because at the bottom of said cavity less vortex occur and thus less substances to be separated are whirled up and finally rinsed out with the medium to be treated.
- centrifugal separators according to the construction discussed are the required high cost piping outside. This piping effort requires a lot of space. Due to this space requirement, it is usually not economically possible to replace in existing systems centrifugal separator of that type in which the medium flows through a pipe from said cavity, by the per se better centrifugal separator of the type in which the medium through two tubes of said Cavity flows out.
- the object of the inventor is to provide a centrifugal separator of the type in which, for the removal of purified medium, two tubes protrude into the cavity in which the separation takes place by centrifugal force.
- the centrifugal separator has a cavity which extends approximately circularly symmetrical about a vertical axis at least in a substantial portion of its height, wherein for the purpose of supplying medium to be treated into the cavity, a feed tube opens tangentially and wherein two of Removal of serving in the cavity treated medium extending tubes coaxially with the axis of the cavity in the cavity, wherein the outer diameter of these two tubes is smaller than the inner diameter of the cavity and these two tubes in the cavity facing each other but spaced open end faces in a height range end, which is spaced from the floor and from the ceiling of the cavity.
- the medium flows in the centrifugal separator according to the invention from similar, as from a known centrifugal separator with two drain pipes, which is advantageous for reasons of separation effect.

- the medium to be treated is supplied through the supply pipe 2, which opens into the cavity 1 as possible, preferably tangentially to the circumferential direction of the cavity 1, preferably in the upper height range of the cavity 1, with the highest possible flow rate. Due to the nature of the supply of the medium and the geometry of the cavity 1, the medium flows in the cavity 1 in a circular motion, whereby a centrifugal force acts on the medium.
- the substance to be separated which is specifically heavier than the medium, more than the medium is forced to the outer layer of the cavity 1, so that there its density increases over its density in the remaining volume range.
- the material to be separated sinks on the lateral surface of the cavity 1 down to its bottom region 5, from where it is removed continuously or discontinuously.

Abstract
Description
Die Erfindung betrifft einen Fliehkraftabscheider für das Abtrennen von wenigstens einem Stoff aus einem flüssigen oder gasförmigen Medium.The invention relates to a centrifugal separator for the separation of at least one substance from a liquid or gaseous medium.
Die
Nachteilig an Fliehkraftabscheidern gemäß der besprochenen Bauweise ist der erforderliche hohe Verrohrungsaufwand außen herum. Dieser Verrohrungsaufwand verursacht hohen Platzbedarf. Auf Grund dieses Platzbedarfes ist es zumeist nicht wirtschaftlich möglich, bei bestehenden Anlagen Fliehkraftabscheider jenes Typs bei denen das Medium nur durch ein Rohr aus besagtem Hohlraum ausströmt, durch die an sich besseren Fliehkraftabscheider jenes Typs zu ersetzen, bei denen das Medium durch zwei Rohre aus besagtem Hohlraum ausströmt.A disadvantage of centrifugal separators according to the construction discussed is the required high cost piping outside. This piping effort requires a lot of space. Due to this space requirement, it is usually not economically possible to replace in existing systems centrifugal separator of that type in which the medium flows through a pipe from said cavity, by the per se better centrifugal separator of the type in which the medium through two tubes of said Cavity flows out.
Der Erfinder hat sich die Aufgabe gestellt, einen Fliehkraftabscheider jenes Typs bereitzustellen, bei welchem für den Abtransport von gereinigtem Medium zwei Rohre in jenen Hohlraum ragen, in welchem die Abscheidung durch Fliehkraft erfolgt. Bei ansonsten gleichen Leistungsdaten soll gegenüber bekannten Bauweisen dazu mit verringertem Platzbedarf das Auslangen gefunden werden.The object of the inventor is to provide a centrifugal separator of the type in which, for the removal of purified medium, two tubes protrude into the cavity in which the separation takes place by centrifugal force. With otherwise identical performance data compared to known constructions to be found with reduced space requirements Auslangen.
Zum Lösen der Aufgabe wird also wie bei der
Als erfindungsgemäße Verbesserung werden folgende neuen Merkmalen vorgeschlagen:
- Ein beidseits offenes Verbindungsrohr, dessen Außendurchmesser kleiner ist als der Innendurchmesser der beiden der Abfuhr von behandeltem Medium dienenden Rohre ragt vom Inneren eines Rohres, welches der Abfuhr von behandeltem Medium dient in das Innere des anderen dieser Rohre.
- Der zwischen dem Verbindungsrohr und den dieses umgebenden Rohren verbleibende Spalt ist offen, sodass er von Medium durchflossen werden kann.
- Eines der beiden der Abfuhr von behandeltem Medium dienenden Rohre ist an seiner vom anderen dieser Rohre abgewandten Stirnfläche verschlossen.
- A connecting tube open on both sides, the outer diameter of which is smaller than the inner diameter of the two treated medium evacuation tubes, protrudes from the inside of a tube serving to remove treated medium into the interior of the other of these tubes.
- The gap remaining between the connecting tube and the tubes surrounding it is open, so that it can be flowed through by medium.
- One of the two tubes serving to remove treated medium is closed at its end remote from the other of these tubes.
Aus dem Hohlraum, in welchem die Abscheidung durch Fliehkraft stattfindet, fließt das Medium bei dem erfindungsgemäßen Fliehkraftabscheider ähnlich ab, wie aus einem bekannten Fliehkraftabscheider mit zwei Abflussrohren, was aus Gründen der Trennwirkung vorteilhaft ist. Dennoch ist der erfindungsgemäße Fliehkraftabscheider bezüglich seiner äußeren Abmessungen und seiner äußeren Anschlüsse gleich wie ein Fliehkraftabscheider, bei welchem nur ein dem Abfluss von behandeltem Medium dienendes Rohr in den Hohlraum in welchem die Fliehkraftabscheidung stattfindet ragt.From the cavity in which the separation takes place by centrifugal force, the medium flows in the centrifugal separator according to the invention from similar, as from a known centrifugal separator with two drain pipes, which is advantageous for reasons of separation effect. Nevertheless, the centrifugal separator according to the invention with respect to its outer dimensions and its outer connections is the same as a centrifugal separator, in which only a pipe serving the outflow of treated medium into the cavity in which the centrifugal separation takes place.
Die Erfindung wird an Hand einer Prinzipskizze zu einer beispielhaften Ausführungsform veranschaulicht:

Fig. 1 : shows in a stylized representation in a vertical sectional view essential for the understanding of the invention parts of a first exemplary centrifugal separator according to the invention. Parts which serve only the mechanical connection between parts are not shown for reasons of clarity. -
Fig. 2 : shows in the same way asFig. 1 a second exemplary centrifugal separator according to the invention.
In dem durch eine äußere Wand 1.1 begrenzten Hohlraum 1 des Fliehkraftabscheiders gemäß
Bestimmungsgemäße wird von abzutrennendem Stoff befreites Medium über das Anschlussrohr 3 aus dem Hohlraum 1 entfernt. Dazu ist dieses Anschlussrohr 3 mit einem ersten Rohr 3.1 der im Hohlraum 1 angeordneten vertikalen Rohre 3.1, 3.2 verbunden. Dieses vertikale Rohr 3.1 ist koaxial mit der Achse des Hohlraums im Hohlraums 1 angeordnet und endet mit offener Stirnfläche im Hohlraum 1 etwa in dessen mittlerer Höhe. Im dargestellten Beispiel ist das offene Ende des vertikalen Rohres 3.1 sein unteres Ende.According to the intended, the medium to be separated from the substance to be separated is removed from the
Ein zweites vertikales Rohr 3.2 ist ebenfalls koaxial mit der Achse des Hohlraums 1 im Hohlraum angeordnet. Es endet mit seinem oberen und offenen Ende unterhalb des darüber befindlichen vertikalen Rohres 3.1. Das untere Ende diese zweiten vertikalen Rohres 3.2 ist verschlossen, allerdings nicht durch einen einfachen ebenen Deckel, sondern durch einen Haubenteil 3.3, welcher im Anschluss an die untere Stirnfläche des vertikalen Rohres 3.2 zuerst eine Erweiterung der Querschnittsfläche des Rohres 3.2 darstellt und erst in weiterer Folge einen Verschluss.A second vertical pipe 3.2 is also arranged coaxially with the axis of the
Ein beidseits offenes Verbindungsrohr 4, erstreckt sich vom Inneren des oberen vertikalen Rohres 3.1 in das Innere des unteren vertikalen Rohres 3.2.An open on both
Für das aus dem Hohlraum 1 zum Rohr 3 fließende Medium stehen somit zwei Strömungswege bereit. Der eine Strömungsweg führt unmittelbar vom Hohlraum 1 in das Rohr 3.1 und durch dieses nach oben zum Rohr 3. Der zweite Strömungsweg führt in das untere Rohr 3.2, in diesem nach unten zum Haubenteil 3.3 und von diesem durch das Verbindungsrohr 4 nach oben zum Rohr 3.Thus, two flow paths are available for the medium flowing out of the
Indem der Zufluss zum unteren vertikalen Rohr 3.2 weit oberhalb des Bodenbereichs 5 des Hohlraums 1 liegt besteht so gut wie keine Gefahr, dass Stoff, welcher schon vom Medium abgetrennt wurde und sich im Bodenbereich 5 sammelt wieder aufgewirbelt wird und in den Ansaugbereich des Rohres 3.2 gelangt, vom weiter oben liegenden Ansaugbereich des Rohres 3.1 ganz zu schweigen.By the inflow to the lower vertical pipe 3.2 is far above the
Der gegenüber dem Querschnitt des Rohres 3.2 erweiterte Querschnitt des Haubenteils 3.3 am unteren Ende des vertikalen Rohres 3.2 wirkt als eine Art Diffusor dahingehend, dass Strömungsenergie des sich drehenden Mediums zurückgewonnen wird, sodass also für den Antrieb der erforderlichen Zirkulationsbewegung des Mediums im Hohlraum 1 weniger Energie zugeführt werden muss.The opposite of the cross section of the tube 3.2 extended cross section of the hood part 3.3 at the lower end of the vertical tube 3.2 acts as a kind of diffuser to the effect that flow energy of the rotating medium is recovered, so so for driving the required circulation movement of the medium in the
In gleicher Weise wirkt auch der erweiterte Querschnittsbereich der Zwischenkammer 3.4, welche das oberen Ende des oberen vertikalen Rohres 3.1 mit dem Anschlussrohr 3 verbindet.In the same way, the expanded cross-sectional area of the intermediate chamber 3.4, which connects the upper end of the upper vertical tube 3.1 with the connecting
Bevorzugt ist das obere Rohr 3.1 der beiden vertikalen Rohre 3.1, 3.2 mit dem nach außen führenden Anschlussrohr 3 verbunden und das untere Rohr 3.2 an seinem unteren Ende verschlossen. Damit wird es gut möglich den bodennahen Bereich der Hohlkammer 1 kreissymmetrisch auszubilden, womit in diesem Höhenbereich weniger Turbulenzen im Medium auftreten und damit weniger abgesunkener abzutrennender Stoff aufgewirbelt wird.Preferably, the upper tube 3.1 of the two vertical tubes 3.1, 3.2 connected to the outwardly leading connecting
Die Überlegungen, Berechnungen und Versuchsanordnungen für die detailliertere Dimensionierung der einzelnen Teile des erfindungsgemäßen Fliehkraftabscheiders können im Rahmen des fachmännischen Handelns von den bekannten Überlegungen, Berechnungen und Versuchsanordnungen zur Dimensionierung bekannter Fliehkraftabscheider hergeleitet werden, weswegen hier nicht weiter darauf eingegangen wird.The considerations, calculations and experimental arrangements for the detailed dimensioning of the individual parts of the centrifugal separator according to the invention can be derived in the context of expert action of the known considerations, calculations and experimental arrangements for dimensioning known centrifugal force, so will not be discussed further here.
Gegenüber bekannten Fliehkraftabscheidern mit nur einem Abflussrohr für behandeltes Medium wird durch die erfindungsgemäße Bauweise die Trennwirkung bei gleichen Außenabmessungen, gleichen Anschlüssen und annähernd gleichen Teilekosten deutlich verbessert.Compared with known centrifugal separators with only one drainage pipe for treated medium, the separation effect with the same external dimensions, the same connections and approximately the same parts costs is significantly improved by the construction according to the invention.
