Description

Die Erfindung betrifft ein Verfahren zur Verarbeitung eines Produktes mittels einer Phasentrennung nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for processing a product by means of a phase separation according to the preamble of claim 1.

Zum technologischen Hintergrund werden die gattungsgemäße WO 86/01436 , die DE 10 2005 021 331 A1 , die DE 697 12 569 T2 und die WO 94/ 06 565 A1 genannt. Die DE 10 2005 021 331 A1 zeigt zwar einen Trennseparator. Hier erfolgt aber die Ableitung einer schwereren Flüssigkeitsphase über einen Auslass, dem eine Drosseleinrichtung zugeordnet ist und nur die Ableitung einer leichteren Flüssigkeitsphase mittels einer Schälscheibe. Die WO 94/ 06 565 A1 offenbart einen Trennseparator, bei dem die leichtere Flüssigkeitsphase mittels einer Schälscheibe und die andere schwere Flüssigkeitsphase mittels einer Ableitvorrichtung mittels schräg zur Radialen verstellbaren Röhrchen erfolgt, die einmalig auf einen gewünschten Radius eingestellt werden, so dass im Betrieb stets die Ableitung dieser Phase erfolgt, aber derart, dass nur ein Teil der Röhrchen in die schwere Phase eintaucht, was die Reibung gering halten soll. Die DE 697 12 569 T2 offenbart einen Trennseparator, bei dem die leichtere Flüssigkeitsphase mittels einer Stauscheibe und die andere schwere Flüssigkeitsphase mittels einem Auslasselement erfolgt, welches mit einer Antriebsvorrichtung an variierende Orte einer freien Flüssigkeitsfläche gedrückt wird, so dass im Betrieb ebenfalls stets die Ableitung dieser Phase erfolgt, wobei möglichst die Eintauchtiefe in diese Phase zur Verringerung des Energieverbrauchs konstant gehalten werden soll.The technological background is the generic WO 86/01436 , the DE 10 2005 021 331 A1 , the DE 697 12 569 T2 and the WO 94/06 565 A1 called. The DE 10 2005 021 331 A1 Although shows a Trennseparator. Here, however, the derivation of a heavier liquid phase via an outlet, which is associated with a throttle device and only the derivation of a lighter liquid phase by means of a paring disc. The WO 94/06 565 A1 discloses a Trennseparator in which the lighter liquid phase by means of a paring disc and the other heavy liquid phase by means of a discharge by means of obliquely adjustable to the radial tubes that are adjusted once to a desired radius, so that in operation always the derivation of this phase takes place, but so in that only part of the tubes are immersed in the heavy phase, which should keep the friction low. The DE 697 12 569 T2 discloses a Trennseparator, in which the lighter liquid phase by means of a baffle plate and the other heavy liquid phase by means of an outlet member which is pressed with a drive device to varying locations of a free liquid surface, so that in operation also always the derivation of this phase takes place, where possible the Immersion depth should be kept constant in this phase to reduce energy consumption.

Beim Betrieb von Trennseparatoren treten Probleme mit der kontinuierlichen Ableitung der schwereren Phase insbesondere dann auf, wenn der Anteil der schwereren Phase relativ zur leichteren Phase sehr gering ist, beispielsweise wenn der Anteil der schwereren Phase am zulaufenden Produkt kleiner als 3%, vorzugsweise kleiner als 1%.When operating Trennseparatoren occur problems with the continuous derivation of the heavier phase, especially when the proportion of the heavier phase relative to the lighter phase is very low, for example, if the proportion of heavier phase at the incoming product less than 3%, preferably less than 1 %.

Die Erfindung hat die Aufgabe, dieses Problem auf einfache Weise zu lösen.The invention has the object to solve this problem in a simple manner.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1, also mit einfachen Mitteln und mit einem sehr einfachen Verfahren.The invention solves this problem by the subject matter of claim 1, that is, with simple means and with a very simple method.

Derart kann sich im Betrieb zunächst stets eine genügende Menge der schwereren Phase weiter außen in der Trommel sammeln, bis es möglich ist, diese Menge an schwererer Phase aus der Trommel abzuleiten. Sodann wird die Ableitung für einen gewissen Zeitraum unterbrochen, bis sich wieder eine genügende Menge an schwerer Flüssigkeitsphase außen in der Trommel gesammelt hat, um sie aus der Trommel abzuleiten. Daneben kann die Feststoffphase ebenfalls - vorzugsweise zeitlich unabhängig von der Entleerung der schweren Flüssigkeitsphase - diskontinuierlich aus der Trommel ausgeworfen werden, beispielsweise durch von einem Kolbenschieber verschiebbare Feststoffaustragsöffnungen.Thus, in operation, a sufficient amount of the heavier phase can always accumulate farther out in the drum until it is possible to remove that amount of heavier phase from the drum. Then the derivative is interrupted for a certain period of time, until again a sufficient amount of has collected heavy liquid phase outside of the drum to drain it out of the drum. In addition, the solid phase can likewise be ejected discontinuously from the drum, preferably by means of solids discharge openings which can be displaced by a piston slide, preferably independently of the emptying of the heavy liquid phase.

Besonders vorteilhaft lässt sich das erfindungsgemäße Verfahren bei der Verarbeitung von pflanzlichen oder tierischen Ölen und Fetten einsetzen, welche nur einen relativ geringen Anteil an schwerer Phase von insbesondere weniger als 3% aufweisen.The process according to the invention can be used particularly advantageously in the processing of vegetable or animal oils and fats, which have only a relatively small proportion of heavy phase, in particular less than 3%.

Weitere vorteilhafte Ausgestaltungen sind den übrigen Unteransprüchen zu entnehmen.Further advantageous embodiments can be found in the remaining subclaims.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels unter Bezug auf die Zeichnung näher beschrieben. Es zeigt:

Fig. 1
einen Schnittansicht einer schematisch dargestellten Separatortrommel mit einer Haube; und
Fig.2
eine schematische Darstellung eines Verschwenken eines Schälorgans auf verschiedene Durchmesser.
The invention will be described with reference to an embodiment with reference to the drawings. It shows:
Fig. 1
a sectional view of a separator drum shown schematically with a hood; and
Fig.2
a schematic representation of a pivoting of a peeling member to different diameters.

Fig.1 zeigt eine an sich kontinuierlich arbeitende Separatortrommel 1, die eine vertikal ausgerichtete Drehachse am Radius r0 aufweist. Fig.1 shows a per se, continuously operating separator drum 1, which has a vertically oriented axis of rotation at the radius r 0 .

Die drehbare Separatortrommel 1 ist auf eine Drehspindel 2 gesetzt, die z.B. direkt oder über einen Riemen angetrieben wird und die drehbar gelagert ist (hier nicht dargestellt). Die Drehspindel 2 kann in ihrem oberen Umfangsbereich konisch ausgestaltet sein. Die Separatortrommel 1 ist von einer sich nicht mit der Trommel drehenden, stillstehenden Haube 3 umgeben.The rotatable separator drum 1 is set on a rotary spindle 2, e.g. is driven directly or via a belt and which is rotatably mounted (not shown here). The rotary spindle 2 may be designed conically in its upper peripheral region. The separator drum 1 is surrounded by a stationary hood 3 that does not rotate with the drum.

Neben dieser Art der Konstruktion sind auch Konstruktionen bekannt, bei denen eine untere Trommel an einer oberen Drehspindel quasi "aufgehängt" ist. Auch hier wird die Trommel aber nur an einem ihrer Enden bzw. im Anschluss an eines ihrer axialen Enden drehbar pendelnd gelagert.In addition to this type of construction, constructions are also known in which a lower drum is quasi "suspended" on an upper rotary spindle. Again, however, the drum is rotatably mounted oscillating only at one of its ends or subsequent to one of its axial ends.

Die vorteilhaft doppelt konische Separatortrommel 1 weist ein Produktzulaufrohr 4 für ein zu schleuderndes Produkt P auf, an das sich ein Verteiler 5 anschließt, welcher mit wenigstens einer oder mehreren Auftrittsöffnungen 6 versehen ist, durch welche zulaufendes Schleudergut in das Innere der Separatortrommel 1 und wenigstens einen Steigekanal 7 des Tellerpakets geleitet werden kann. Eine Zuleitung durch die Spindel z.B. von unten ist ebenfalls denkbar.The advantageous double-conical separator drum 1 has a product feed pipe 4 for a product P to be hurled, to which a distributor 5 adjoins, which is provided with at least one or more outlet openings 6, through which incoming centrifuged material into the interior of the separator drum 1 and at least one riser channel 7 of the plate package can be passed. A supply line through the spindle, for example, from below is also conceivable.

Hier ist die Konstruktion derart gewählt, dass die Austrittsöffnungen 6 unterhalb eines Steigekanals 7 in einem Tellerpaket 8 aus konisch geformten Trenntellern (nicht dargestellt) liegen.Here, the construction is chosen such that the outlet openings 6 below a riser channel 7 in a plate package 8 of conically shaped separating plates (not shown).

Nach oben wird das Tellerpaket 8 von einem Scheideteller 9 abgeschlossen, der einen größeren Durchmesser aufweist als das Tellerpaket 8.At the top, the plate package 8 is closed by a separator plate 9, which has a larger diameter than the plate package eighth

Innerhalb des Trenntellerpaktes und dort vorzugsweise innerhalb des Steigekanals 7 bildet sich im Betrieb bei einer entsprechenden Rotation der Trommel an einem bestimmten Radius - der Emulsionslinie oder Trennlinie (auch E-Linie genannt) - eine Trennzone zwischen einer leichteren Flüssigkeitsphase LP und einer schwereren Flüssigkeitsphase HP aus.Within the separator plate pact, and preferably within the riser channel 7, a separation zone between a lighter liquid phase LP and a heavier liquid phase HP is formed during operation with a corresponding rotation of the drum at a certain radius - the emulsion line or separation line (also called E line) ,

Die Feststoffphase ist mit S bezeichnet. Sie wird diskontinuierlich durch Feststoffaustragsöffnungen 10 abgeleitet, welche diskontinuierlich mit Hilfe eines Kolbenschiebers 11 geöffnet und geschlossen werden können.The solid phase is designated S. It is discharged discontinuously through solids discharge openings 10, which can be discontinuously opened and closed by means of a piston slide 11.

Die leichtere Flüssigkeitsphase LP (light phase) wird an einem inneren Radius rLP mit in eine Schälkammer 12 und von dort mit Hilfe eines ersten Schälorgans, einer Schälscheibe 13 (auch Greifer genannt), aus der Trommel geleitet.The lighter liquid phase LP (light phase) is conducted at an inner radius r LP into a peeling chamber 12 and from there by means of a first peeling member, a peeling disk 13 (also called a gripper), out of the drum.

Mit Hilfe des durch die Rotationsenergie der Flüssigkeit entstehenden Staudrucks wirkt die Schälscheibe wie eine Pumpe. Der Schälscheibe kann z.B. außerhalb des Separators in deren nachgeschalteter Ableitung ein Ventil (hier nicht dargestellt) zur Androsselung nachgeschaltet sein.With the help of the dynamic pressure created by the rotational energy of the fluid, the paring disc acts like a pump. The peeling disc may e.g. be downstream of the separator in the downstream derivative of a valve (not shown here) for throttling.

Der Einlass 14 in die Schälscheibe 13 liegt auf einem festen Durchmesser, der nicht verstellbar ist.The inlet 14 in the paring disc 13 is located on a fixed diameter, which is not adjustable.

Die schwere Flüssigkeitsphase HP (heavy phase) strömt dagegen um den äußeren Umfang des Scheidetellers 9 herum durch einen Ableitungskanal 15 in eine zweite Schälkammer 15, in welcher ein zweites Schälorgan 16 angeordnet ist.By contrast, the heavy phase HP (heavy phase) flows around the outer circumference of the divider plate 9 through a discharge channel 15 into a second peeling chamber 15, in which a second peeling element 16 is arranged.

Dieses Schälorgan ist derart ausgebildet, dass sein Einlass bzw. seine Einlassöffnung 17 innerhalb der Schälkammer kontinuierlich oder diskontinuierlich verstellbar ist (siehe hierzu auch Fig. 2), so dass wenigstens ein erster innerer Radius Ri und ein äußerer Radius Ra in der Trommel erreicht werden können.This peeling member is designed such that its inlet or its inlet opening 17 within the peeling chamber is continuously or discontinuously adjustable (see also Fig. 2 ), so that at least a first inner radius Ri and an outer radius Ra in the drum can be achieved.

Dies kann beispielsweise dadurch verwirklicht werden, dass das zweite Schälorgan 16 als ein Schälrohr ausgebildet ist, welches im Schnitt der Fig. 1 L-förmig ausgebildet ist und einen ersten Abschnitt 18 aufweist, welcher in der Schälkammer radial ausgerichtet ist und einen zweiten, parallel zur Drehachse D ausgerichteten Abschnitt 19, welcher nach oben aus dem drehenden System geführt ist, wobei der
Abschnitt 19 um seine Längsachse auf dem Radius r19 drehbar ist. Ein Verschwenken des Schälrohrs 18 um diese Drehachse r19 (siehe Fig. 2) ermöglicht es, den Einlass 17 zwischen dem erwähnten inneren Radius Ri (gestrichelte Darstellung in Fig. 2) und dem äußeren Radius Ra zu verschwenken (nicht gestrichelte Darstellung in Fig. 2).This can be realized, for example, in that the second peeling member 16 is designed as a peeling tube, which in section the Fig. 1 L-shaped and has a first portion 18 which is radially aligned in the peeling chamber and a second, parallel to the rotation axis D aligned portion 19, which is guided upward from the rotating system, wherein the
Section 19 is rotatable about its longitudinal axis on the radius r19. A pivoting of the peeling tube 18 about this axis of rotation r19 (see Fig. 2 ) allows the inlet 17 between the mentioned inner radius Ri (dashed line in FIG Fig. 2 ) and the outer radius Ra to pivot (not dashed line in FIG Fig. 2 ).

Vorzugsweise vorteilhaft außerhalb des Separators ist eine Vorrichtung zum Verschwenken des Schälrohrs angeordnet.Preferably, outside the separator, a device for pivoting the peeling tube is arranged.

Das Verschwenken an sich kann auf verschiedenste Weise realisiert werden, so beispielsweise mittels eines Zahnradgetriebes, eine Hebelmechanismus oder mittels eines hydraulischen oder pneumatischen Antriebs.The pivoting per se can be realized in a variety of ways, such as by means of a gear transmission, a lever mechanism or by means of a hydraulic or pneumatic drive.

Hierzu kann beispielsweise am Rohraußendurchmesser ein Verzahnungssegment 20 ausgebildet sein, das mit einem Antriebszahnrad 21 eines ansonsten nicht weiter dargestellten Getriebes kämmt, welchem ein Elektromotor (nicht dargestellt) vorgeschaltet ist. Der Antrieb und die Getriebeverbindung zum Schälorgan können aber auch auf andere Weise realisiert werden.For this purpose, for example, a toothed segment 20 may be formed on the outer pipe diameter, which meshes with a drive gear 21 of a transmission, which is otherwise not shown, to which an electric motor (not shown) is connected upstream. The drive and the gear connection to the peeling member can also be realized in other ways.

Der vorstehend beschriebene Dreiphasen-Trennseparator mit der Trommel 1 mit vertikaler Drehachse eignet sich zur Trennung verschiedenster Flüssigkeitsgemische wie beispielsweise zur Abtrennung von Wasser aus Öl.The above-described three-phase Trennseparator with the drum 1 with a vertical axis of rotation is suitable for the separation of various fluid mixtures such as for the separation of water from oil.

Beim Betrieb von Trennseparatoren treten Probleme mit der kontinuierlichen Ableitung der schwereren Phase insbesondere dann auf, wenn nur sehr kleine Volumenströme dieser Phase zu verarbeiten sind bzw. wenn der Anteil der schwereren Phase relativ zur leichteren Phase sehr gering ist, beispielsweise wenn der Anteil der schwereren Phase am zulaufenden Produkt kleiner als 3%, vorzugsweise kleiner als 1%, ganz besonders bevorzugt 0,5 %.
Dieses Problem wird mit Hilfe des dargestellten Trennseparators dadurch gelöst, dass die schwerere Flüssigkeitsphase Hp nur diskontinuierlich ausgetragen wird.When operating Trennseparatoren occur problems with the continuous discharge of the heavier phase, especially if only very small volume flows of this phase are to be processed or if the proportion of the heavier phase relative to the lighter phase is very low, for example, if the proportion of heavier phase on the incoming product less than 3%, preferably less than 1%, most preferably 0.5%.
This problem is solved by means of the illustrated Trennseparators in that the heavier liquid phase Hp is discharged only discontinuously.

Dies kann nach einer besonders vorteilhaften Variante der Erfindung dadurch realisiert werden, dass das verstellbare zweite Schälorgan 16 in einem ersten Schritt i) auf einen so kleinen Radius Ri eingestellt ist oder - wenn es nicht bereits auf diesem inneren Radius aufgestellt ist - wird, dass es im Betrieb nicht in die schwere Phase HP eintaucht. Derart sammelt sich die schwere Phase - beispielsweise Wasser bei der Trennung von Wasser und Öl - außen in der Trommel 1 an, so dass der Radius, bis zu dem die schwerere Phase, insbesondere das Wasser, reicht, in der Trommel 1 von außen nach innen hin ansteigt.This can be realized according to a particularly advantageous variant of the invention in that the adjustable second peeling member 16 is set in a first step i) on such a small radius Ri or - if it is not already placed on this inner radius - that not immersed in the heavy phase HP during operation. Thus, the heavy phase - such as water in the separation of water and oil - accumulates outside in the drum 1, so that the radius to which the heavier phase, especially the water, extends in the drum 1 from outside to inside goes up.

Beim Erreichen eines vorgegebenen inneren Radius, beispielsweise dann, wenn die schwerere Flüssigkeitsphase HP - insbesondere das Wasser - den Einlass 17 des Schälorgans 16 erreicht (oder beispielsweise nach Ablauf eines vorgegebenen Zeitintervalls), wird der Einlass 17 des Schälorgans 16 in einem Schritt ii) auf einen größeren Radius Ra (siehe Fig. 1 und 2) derart verstellt, dass er in die schwerere Flüssigkeitsphase HP eintaucht, so dass die schwerere Flüssigkeitsphase HP aus der Trommel 1 abgeleitet wird. Da mehr schwerere Flüssigkeitsphase HP abgeleitet wird, als mit dem zugeleiteten Produkt in die Trommel fließt, steigt infolge des Ableitens der maximale Radius, bis zu welchem sich die schwerere Flüssigkeitsphase HP in der Trommel 1 erstreckt, weiter radial relativ zur Drehachse D nach außen an. Sobald derart eine genügende Menge der schwereren Flüssigkeitsphase HP abgeschöpft ist, wird der Einlass 17 wieder auf einen - vorzugsweise den inneren Radius Ri aus Schritt i) - verschwenkt, so dass erneut entsprechend Schritt i) das Ableiten der schwereren Phase HP unterbrochen wird.Upon reaching a predetermined inner radius, for example, when the heavier liquid phase HP - especially the water - reaches the inlet 17 of the peeling member 16 (or for example after a predetermined time interval), the inlet 17 of the peeling member 16 in a step ii) on a larger radius Ra (see Fig. 1 and 2 ) is adjusted so that it dips into the heavier liquid phase HP, so that the heavier liquid phase HP is discharged from the drum 1. As more heavier liquid phase HP is discharged than flows into the drum with the product supplied, as a result of the discharge, the maximum radius up to which the heavier liquid phase HP extends in the drum 1 continues to increase radially relative to the rotation axis D to the outside. As soon as such a sufficient amount of the heavier liquid phase HP has been skimmed off, the inlet 17 is again pivoted to one, preferably the inner radius Ri from step i), so that again according to step i) the discharge of the heavier phase HP is interrupted.

Es ist besonders vorteilhaft, im Betrieb beim Anfahren zunächst nur die schwere Phase - beispielsweise Wasser - in die Trommel 1 zu leiten und erst dann, wenn sich ein genügender Wasserpegel ausgebildet hat, das eigentliche zu verarbeitende Produkt zuzuleiten.It is particularly advantageous in operation when starting initially only the heavy phase - for example water - to pass into the drum 1 and only when a sufficient water level has formed, the actual product to be processed zuzuleiten.

Derart können auch schwerere Flüssigkeitsphasen aus einem Flüssigkeitsgemisch abgetrennt werden, in welchem der Anteil der schwereren Phase HP relativ zur leichteren Phase LP nur sehr gering ist.In this way, even heavier liquid phases can be separated from a liquid mixture in which the proportion of the heavier phase HP relative to the lighter phase LP is only very small.

Als vorteilhaft zu erwähnen ist insbesondere auch, dass mit dem erfindungsgemäßen durch die verminderte Reibleistung eine Energieeinsparung erzielbar ist.It is also to be mentioned as advantageous, in particular, that energy savings can be achieved with the reduced friction power of the invention.

Der Zeitpunkt des Abschöpfens der schweren Phase kann auch über Zeitsteuerung gesteuert werden und besonders einfach beispielsweise in festen Intervallen erfolgen.The timing of skimming the heavy phase may also be controlled via timing and may be particularly simple, for example, at fixed intervals.

Alternativ und mit höherer Präzision kann der Zeitpunkt des Abschöpfens mittels einer Sensierung und/oder Messung erfolgen (vorteilhaft wären insofern insbesondere: ein Kontaktmanometer, ein Durchflussmesser, ein Wassersensor im Ablauf).Alternatively, and with higher precision, the time of skimming by means of a sensing and / or measurement can be carried out (in this respect would be particularly advantageous: a contact pressure gauge, a flow meter, a water sensor in the process).

  1. A method for processing a product by means of phase separation in at least two liquid phases in conjunction with additional clarification of solids,
    a. wherein the processing of the product occurs in a continuously operating centrifuge which is arranged as a separator, which comprises a rotatable drum (3) with vertical rotational axis (D), in which a separator disk stack with risers is arranged, and is provided with a product feed tube (4) and at least two separator elements (13, 16) for discharging a lighter and a heavier liquid phase from the drum and solid discharge openings (10) for discharging a solid phase from the drum, with a separation zone being formed between the lighter and the heavier liquid phase (HP, LP) in the centrifuge,
    b. wherein the lighter liquid phase (LP) is discharged continuously and the heavier liquid phase (HP) and the solid phase are discharged discontinuously from the drum (1)characterized in that
    c. for the discontinuous discharge of the heavier liquid phase the separation element (16) is moved to different radii (Ri, Ra) for discharging the heavier phase,
    d. wherein the adjustable separation element (16) is set in a first step i) to such a small radius, or will be set to such a small radius unless it has already been set to said inner radius, that its inlet opening (17) will not immerse in the heavy liquid phase HP in operation, so that the heavier liquid phase will accumulate outside in the drum, with the radius up to which the heavier liquid phase reaches will rise in the drum from the outside to the inside, and that when the heavier liquid phase has risen up to an inner radius, e.g. when the heavier liquid phase has reached the inlet (17) of the separator element (16), the inlet (17) of the separator element will be set in a step ii) to a larger radius, so that the inlet (17) will immerse in the heavier liquid phase, by means of which the heavier liquid phase will be discharged from the drum (1).
  2. A method according to claim 1, characterized in that a product is processed, the fraction of the heavier phase of which is relatively low in relation to the lighter phase.
  3. A method according to claim 1 or 2, characterized in that the heavier liquid phase (HP) and the solid phase are discharged discontinuously from the drum (1) at different times.
  4. A method according to one of the preceding claims, characterized in that after the discharge of the heavier liquid phase the inlet (17) of the movable separator element (16) will be pivoted back to an inner radius, so that the discharge of the heavier phase is interrupted again according to step i).
  5. A method according to claim 4, characterized in that after the discharge of the heavier liquid phase at such time when the heavier liquid phase reaches a specific outer radius the inlet (17) of the movable separator element (16) is pivoted back to an inner radius again, so that the discharge of the heavier phase is interrupted again according to step i).
  6. A method according to one of the preceding claims, characterized in that after the discharge of the heavier liquid phase after the passage of a predetermined period of time the inlet (17) of the movable separator element (16) is pivoted back to an inner radius again, so that the discharge of the heavier phase is interrupted again according to step i).
  7. A method according to one of the preceding claims, characterized in that an oil-water-solid mixture is processed as the product.
  8. A method according to one of the preceding claims, characterized in that the fraction of the heavier phase in the incoming product is less than 3%, preferably less than 1%.
