Description
Die Erfindung betrifft einen Turboverdichter, der zur Förderung eines Mehrphasengemisches geeignet ist, mit einem eine Leiteinrichtung aufweisenden Gehäuse und einer Welle mit wenigstens einem Laufrad.The invention relates to a turbocompressor, which is suitable for conveying a multi-phase mixture, with a housing having a guide and a shaft with at least one impeller.
Turboverdichter, die auch als Turbokompressor bezeichnet werden, werden zum Fördern eines Fluids durch Übertragung kinetischer Energie in Form eines Drehimpulses eingesetzt. Ein gefördertes Gas wird dabei in einem Verdichter komprimiert. Eine typische Anwendung ist die Förderung von Erdgas, allerdings kann dabei das Problem auftreten, dass das geförderte Erdgas eine Gasphase und eine Flüssigkeitsphase aufweist. Übliche Turboverdichter sind allerdings nicht für die Förderung von Flüssigkeitstropfen geeignet, da diese zu Erosion im Gehäuse des Turboverdichters oder an Laufrädern führen können.Turbo compressors, also referred to as turbocompressors, are used to convey a fluid by transmitting kinetic energy in the form of angular momentum. A transported gas is compressed in a compressor. A typical application is the extraction of natural gas, however, the problem may arise that the natural gas produced has a gas phase and a liquid phase. However, conventional turbocompressors are not suitable for the promotion of liquid droplets, as they can lead to erosion in the housing of the turbocompressor or on wheels.
Um dieses Problem zu vermeiden, ist bereits vorgeschlagen worden, einen auf Zentrifugalabscheidung basierenden Separator in den Turboverdichter zu integrieren. Allerdings ist der Bauaufwand für einen zusätzlichen Separator vergleichsweise hoch. Außerdem wurde festgestellt, dass auch beim Einsatz eines Separators kurzzeitig sogenannte Slugs (Flüssigkeitspfropfen) durchschlagen, so dass der Turboverdichter zumindest kurzzeitig ein Gemisch aus Gas und Flüssigkeit fördern muss. Die geförderte Flüssigkeit kann sowohl Wasser als auch Öl umfassen.In order to avoid this problem, it has already been proposed to integrate a separator based on centrifugal separation into the turbocompressor. However, the construction cost of an additional separator is comparatively high. In addition, it was found that so-called slugs (liquid clogging) penetrate for a short time even when using a separator, so that the turbocompressor must at least temporarily convey a mixture of gas and liquid. The pumped liquid may include both water and oil.
Aus der
Der Erfindung liegt daher die Aufgabe zugrunde, einen Turboverdichter anzugeben, der für die Förderung von in einem Gas enthaltenen Flüssigkeitstropfen geeignet ist.The invention is therefore based on the object to provide a turbocompressor, which is suitable for the promotion of liquid drops contained in a gas.
Zur Lösung dieser Aufgabe ist bei einem Turboverdichter der eingangs genannten Art erfindungsgemäß vorgesehen, dass er an der Saugseite eine von dem Mehrphasengemisch durchströmbare Expansionskammer und eine stromabwärts angeordnete Kontraktionskammer aufweist.To achieve this object, it is provided according to the invention in a turbocompressor of the type mentioned that it has on the suction side of an expansion chamber through which the multiphase mixture can flow and a contraction chamber arranged downstream.
Die Erfindung beruht auf der Erkenntnis, dass mittels der im Ansaugbereich angeordneten Expansionskammer und der zugehörigen Kontraktionskammer eine Homogenisierung des Mehrphasengemisches bewirkt werden kann, bei der sich feine Tröpfchen der flüssigen Phase bilden, die von dem Turboverdichter gefördert werden können. In der Expansionskammer findet eine plötzliche Expansion statt, beim Passieren der nachfolgenden Kontraktionskammer bilden sich die feinen Tröpfchen, die eine Förderung erlauben. Auf diese Weise kann der zulässige Anteil der flüssigen Phase erhöht werden.The invention is based on the recognition that homogenization of the multiphase mixture can be effected by means of the expansion chamber arranged in the intake region and the associated contraction chamber, in which form fine droplets of the liquid phase, which can be conveyed by the turbo compressor. In the expansion chamber, a sudden expansion takes place, when passing the subsequent contraction chamber form the fine droplets that allow a promotion. In this way, the allowable proportion of the liquid phase can be increased.
Bei dem erfindungsgemäßen Turboverdichter wird es bevorzugt, dass die Expansionskammer und die Kontraktionskammer vor einem Ansaugstutzen des Turboverdichters angeordnet sind. Die beiden Kammern können somit als separate Vorrichtung ausgebildet sein, die an der Saugseite eines Turboverdichters angeordnet oder angebracht ist. Alternativ kann es jedoch auch vorgesehen sein, dass die Expansionskammer und die Kontraktionskammer in einem Ansaugstutzen des Turboverdichters angeordnet sind. Bei dieser Ausgestaltung sind die beiden Kammern in den Turboverdichter, nämlich in den Ansaugstutzen des Turboverdichters, integriert, dadurch ergibt sich eine besonders kompakte Bauweise.In the turbocompressor according to the invention, it is preferred that the expansion chamber and the contraction chamber are arranged in front of an intake port of the turbocompressor. The two chambers can thus be formed as a separate device, which is arranged or mounted on the suction side of a turbocompressor. Alternatively, however, it may also be provided that the expansion chamber and the contraction chamber are arranged in an intake pipe of the turbocompressor. In this embodiment, the two chambers in the turbocompressor, namely in the intake of the turbocompressor, integrated, this results in a particularly compact design.
Eine weitere Verbesserung des erfindungsgemäßen Turboverdichters kann erzielt werden, wenn die Expansionskammer einen sich in Strömungsrichtung konusförmig vergrößernden Abschnitt aufweist. Diese geometrische Ausgestaltung bewirkt eine Verringerung von Reibungsverlusten. In ähnlicher Weise kann es bei dem erfindungsgemäßen Turboverdichter vorgesehen sein, dass die Kontraktionskammer einen sich in Strömungsrichtung konusförmig verjüngenden Abschnitt aufweist. Auch durch diese Maßnahme werden Strömungsverluste verringert. Insbesondere kann die Kontraktionskammer als Venturidüse ausgebildet sein, in der eine Druckerhöhung durch Verringerung des Volumens stattfindet.A further improvement of the turbocompressor according to the invention can be achieved if the expansion chamber has a conically enlarging section in the flow direction. This geometric design causes a reduction of friction losses. Similarly, it may be provided in the turbocompressor according to the invention that the contraction chamber has a conically tapering in the flow direction section. Also by this measure flow losses are reduced. In particular, the contraction chamber may be formed as a venturi, in which an increase in pressure takes place by reducing the volume.
