Abstract

The invention relates to a turbocompressor (1, 11) that is suitable for conveying a multi-phase mixture, comprising a housing (2) having a guiding device (3) and comprising a shaft (4) having at least one impeller (5), wherein the turbocompressor (1, 11) has an expansion chamber (7, 12) through which the multi-phase mixture can flow on the suction side (6) and a contraction chamber (9, 13) arranged downstream.

Description

Turbocompressor
Technical field
The present invention relates to a kind of turbocompressor that is suitable for transporting multiphase mixture, described turbocompressor has with the housing of guiding device with the axle of at least one impeller.
Background technique
Transport fluid also referred to as the turbocompressor for turbocharger for the kinetic energy that is rotary pulse form by transmission.At this, the gas being transported is compressed in compressor.Typical application is to transport rare gas, but there will be following problems at this: the rare gas being transported has gas phase and liquid phase.But common turbocompressor is not suitable for transporting drop, because described drop can cause corrosion in the housing of turbocompressor or the corrosion on impeller.
Propose for fear of this problem: the separator based on centrifugal settling is integrated in turbocompressor.But it is relatively high expending for the structure of additional separator.In addition fixed, in the time using separator, also puncture momently so-called liquid plug (slug) (liquid slug), make turbocompressor must transport at least momently the mixture being formed by gas and liquid.The liquid transporting can comprise water and oil.
Known a kind of for the separation equipment from gaseous medium separating liquid particle from DE 10 2,005 003 037 A1.Known a kind of equipment for separating of being included in the oil ingredient in the air amount of internal combustion machine from DE 41 19 794 A1.Known a kind of for the equipment from exhaust stream separating particles from DE 195 15 352 A1.
Summary of the invention
Therefore, the present invention is based on following object: propose a kind of turbocompressor, described turbocompressor is suitable for transporting the drop being included in gas.
In order to realize this object, according to the present invention, in the turbocompressor of the type of mentioning at the beginning, propose: described turbocompressor has in suction side can be by the expansion chamber of multiphase mixture percolation and the retract chamber that is arranged on downstream.
The present invention is based on following knowledge: can cause the homogenization of multiphase mixture by means of the retract chamber that is arranged on the expansion chamber that sucks in region and subordinate, wherein form the trickle droplet of liquid phase, described trickle droplet can be transported by turbocompressor.Unexpected expansion occurs in expansion chamber, and in the time of the retract chamber by follow-up, formation allows the trickle droplet transporting.Can improve the liquid phase share being allowed with which.
In turbomachine compressor according to the present invention preferably: expansion chamber and retract chamber are arranged on the upstream of the suction connection of turbocompressor.Therefore these two chambers can be configured to independent equipment, described equipment setting or be placed in the suction side of turbocompressor.But as an alternative, also can propose: expansion chamber and retract chamber are arranged in the suction connection of turbocompressor.In this design proposal, these two chambers are integrated in the suction connection that in turbocompressor, is integrated into turbocompressor, obtain thus especially compact structure type.
If expansion chamber have flow direction upper conical portion's section of increasing, can further improve according to turbocompressor of the present invention so.Design proposal on this geometrical construction causes the reduction of frictional loss.In turbocompressor according to the present invention, can propose in a similar fashion: retract chamber has portion's section of taper ground convergent on flow direction.Also flow losses have been reduced by this measure.Especially, retract chamber can be configured to Venturi nozzle, in described Venturi nozzle, because volume reduces, pressure raising occurs.
Brief description of the drawings
Set forth the present invention according to embodiment with reference to accompanying drawing below.
Accompanying drawing is schematic view and illustrates:
Fig. 1 illustrates the first embodiment according to turbocompressor of the present invention; With
Fig. 2 illustrates the second embodiment according to turbocompressor of the present invention.
Embodiment
Turbocompressor 1 shown in Figure 1 comprises the housing 2 schematically illustrating, described housing has guiding device 3 and the axle 4 with impeller 5.Axle 4 has multiple impellers that set gradually in the axial direction, because the reason of general view only illustrates impeller 5.
When transporting by turbocompressor 1 when comprising gas phase and also having the multiphase mixture of liquid phase, there is following situation: although exist the separator liquid slug that is arranged on upstream to be still inhaled into, described liquid slug has adverse influence to the parts of turbocompressor 1.Therefore, turbocompressor 1 has expansion chamber 7 in suction side 6, and described expansion chamber has than the larger cross section of pipeline 8 passing into wherein.In the time that the medium being transported flow in expansion chamber 7 via pipeline 8, expand.Retract chamber 9 connects on described expansion chamber 7, and described retract chamber has the cross section less than expansion chamber 7.Correspondingly, again compressed in retract chamber 9 along the mobile fluid of the direction of arrow 10.
Because the expansion of emergent stream in expansion chamber 7 and the unexpected contraction that is being arranged on the stream occurring in the retract chamber 9 in downstream form trickle droplet.To be included in the liquid slug homogenization of the uneven distribution in multiphase mixture if desired with which, in other words, dwindle the size of droplet and form equally distributed droplet.Equally distributed droplet in gas liquid mixture can easily pass through compressor, and does not occur corrosion.Correspondingly, in the multiphase mixture substantially existing with gaseous form, can allow higher liquid fraction, this is essential for underwater use in addition.Separation device can be arranged on the upstream of turbocompressor 1.Experiment draws: the droplet share that can realize at least 70% liquid phase by the combination of expansion chamber and retract chamber.
Fig. 2 illustrates the second embodiment of turbocompressor 11, and described turbocompressor is similar to turbocompressor shown in Figure 11 and constructs.Therefore, apply and reference character identical in the first embodiment for the parts that conform to.
Conform to the first embodiment, turbocompressor 11 comprises housing 2, and described housing has guiding device 3 and the axle 4 with at least one impeller 5.
In turbocompressor 11, expansion chamber 12 is configured to, make its have by the flow direction shown in arrow 10 upper conical portion's section of increasing.In this design proposal of expansion chamber 12, flow losses are less compared with the first embodiment's expansion chamber 7.The retract chamber 13 that is arranged on expansion chamber 12 downstreams is configured in a similar fashion, makes it have the portion's section at upper conical ground of flow direction convergent.Causing the unexpected expansion of flowing medium by expansion chamber 12 and the combination of retract chamber 13 that is arranged on downstream, is then the unexpected contraction of flowing medium, obtains being thus included in the desired uniform formation and distribution of the liquid droplets in gas phase.Correspondingly, the fluid becoming a mandarin in suction side 6 has the droplet distributing subtly, and described droplet can easily pass through the compressor stage of turbocompressor 11.
