Definitions

  • the invention relates to a contour ring for a radial turbomachine, in particular for a compressor, with a flow contour of the standing contour ring.
  • the invention is concerned with a method for operating a radial turbomachine with such a contour ring.
  • axial, radial, tangential or circumferential direction are always related to an axis or axis of rotation of a rotor of the radial turbomachine.
  • the axis of rotation is always the axis of rotation of at least one radial turbine engine impeller through which the process fluid flows and which, for example in the case of a radial turbocompressor, deflects the flow direction of the process fluid from the axial direction into the radial direction, and in this case the process fluid by means of that in the radial turbine engine impeller Blades defined flow channels accelerated due to the rotation of the rotor.
  • the flow of the process fluid is delayed in a diffuser which is generally located downstream after the radial turbine machine impeller, so that there is an increase in the pressure of the process fluid.
  • Radial turbomachinery includes both compressors and expanders. Basically, these are so-called flow machines, in which technical work is either removed from a process fluid or technical work is transferred to a process fluid.
  • the preferred field of application of the invention are compressors in a corresponding centrifugal design. In such radial turbine machines, process fluids are deflected from the axial flow direction along the axis of rotation of a rotor into a radial direction - or vice versa.
  • Some process fluids have the peculiarity of appearing partly in liquid or solid or pasty form or of converting into such states or aggregate states. For example, due to the process, raw gas during compression tends to polymerize above a certain temperature. Corresponding polymerizations, some of which are solid or liquid, or of a transition form between solid and liquid, tend to adhere to flow-guiding elements of the radial turbomachine. In particular in the area of the running play between rotating and rotating components of the radial turbocompressor, running build-up bridging can occur due to these build-ups, which disrupt the operation of the radial turbo machine. These phenomena also have an impact on the selection and design of the flow-carrying components.
  • the radial turbomachine impeller is regularly selected as a closed impeller when compressing raw gas.
  • Closed impellers have a wheel disk connected to the shaft of the rotor, rotor blades attached to the wheel disk and a cover disk opposite the wheel disk, the rotor blades connecting the cover disk to the wheel disk.
  • the cover disk essentially ensures that the flow channels within the impeller are closed radially and axially to a stator of the radial turbomachine. If buildup occurs within these flow channels of the impeller, bridging the play due to these buildup is unlikely, since the running play between the outside of the cover plate and the stator of the radial turbomachine is arranged.
  • the invention proposes a contour ring of the type defined in the introduction with the additional features of independent claim 1. Furthermore, a method according to the method claim for operating a radial turbomachine with such a contour ring is proposed.
  • the dependent subclaims each contain advantageous developments of the invention.
  • the flow contour has a surface that is permeable to a liquid or gaseous cleaning agent, with the contour ring below the surface distribution channels having, wherein the distribution channels are fluidly connected to a supply unit for the cleaning agent of the contour ring.
  • the contour ring is provided for a radial turbomachine, in particular for a compressor.
  • a contour ring is understood by the person skilled in the art to mean a component for arrangement with respect to an open radial turbine machine impeller which can be rotated about an axis of rotation, such that open flow channels are restricted to a wheel disc of the rotatable radial turbine machine impeller by means of a flow contour of the standing contour ring with an intermediate arrangement of a running play.
  • the invention particularly expediently proposes that the contour ring have distribution channels below the surface, which are fluidly connected to a supply unit for a cleaning agent of the contour ring.
  • the radial turbomachine with a contour ring according to the invention can be put into operation, even according to the method according to the invention, and the flow-carrying components can be cleaned during operation by conveying cleaning agents to the flow-guiding flow contour of the contour ring by means of the supply unit.
  • the distribution channels distribute the cleaning agent originating from the supply unit on the surface of the flow contour.
  • the flow contour is arranged here relative to the radial turbine machine impeller, which is preferably designed to be open and rotatable about an axis of rotation, so that open flow channels relative to a wheel disc of the rotatable radial turbine machine impeller are delimited by means of the flow contour of the standing contour ring with an intermediate arrangement of a running play. If there is buildup in the area of the running game, the cleaning agent will remove these buildup.
  • the contour ring formation and the method according to the invention are in particular This is because it is where the detergent enters the process exactly where there is any buildup.
  • a radial turbomachine equipped according to the invention and the method according to the invention are much more powerful than conventional efficiency-increasing tests in preventing buildup, it is also possible according to the invention for the first time to carry out permanently trouble-free operation of openly designed impellers with process fluids at risk of adhesion.
  • the contour ring is particularly expediently undivided in a circumferential direction with respect to the axis of rotation of the radial turbomachine.
  • the undivided design has on the one hand the advantage that any sealing of joints can be saved and on the other hand the network of distribution channels according to the invention can be designed undisturbed by a possible parting joint below the surface for supplying the cleaning agent.
  • the permeable surface is particularly expediently designed as a coating of a base body of the contour ring.
  • the permeability of this coating is particularly preferably achieved by means of an open porosity of the coating.
  • a further advantageous development of the invention provides that the distribution channels are divided into at least two fluid-conducting distribution channel groups which are separate from one another and which are connected to one another in the contour ring at most at the entrance and / or exit of the distribution route defined by means of the distribution channels.
  • the distribution of the cleaning fluid can be locally optimized and, for example, adapted to the main points of attachment.
  • the pressure of the cleaning agent provided by the supply unit it is also possible for the pressure of the cleaning agent provided by the supply unit to be particularly efficient for distributing and preventing buildup can be exploited.
  • the cleaning agent is distributed through the distribution channels to the surface of the flow contour by means of gravity.
  • both the distribution channels themselves and the supply unit can be designed accordingly.
  • the supply unit can be arranged, for example, with a tank at a corresponding height above the contour ring, so that a largely fail-safe supply with the cleaning agent is guaranteed.
  • the contour ring has a cooling device for cooling the contour ring.
  • This cooling device particularly preferably has cooling channels, these cooling channels in particular being able to be at least partially connected to the distribution channels in such a way that there is fluid or at least unidirectional access or exchange between the cooling device and the distribution channels. Additional cooling reduces the tendency to form adherent portions with many process fluids.
  • FIGS. 1 - 4 each schematically show longitudinal sections through contour rings COR according to the invention.
  • Identical reference numerals in the different figures mean identical components.
  • Figure 1 shows in addition to the contour ring COR according to the invention also its arrangement in a radial turbomachine RTM, which is designed as a compressor CP.
  • the Figure 3 also shows the contour ring COR according to the invention together with a radial turbo machine impeller IMP - impeller IMP for short - of a compressor CP. All longitudinal sections of the Figures 1 to 4 are shown along an axis of rotation X of a shaft SH of a rotor, to which the impeller IMP also belongs.
  • circumferential direction CDR is related to the axis of rotation X.
  • terms such as axial, radial, tangential or circumferential direction CDR are related to the axis of rotation X, unless stated otherwise.
  • FIG. 1 shows in addition to the contour ring COR according to the invention also the arrangement of essential other components of the radial turbomachine RTM or the compressor CP.
  • a process fluid PFL flows axially into the impeller IMP through an inlet INL.
  • the impeller IMP accelerates the process fluid PFL radially outward as a result of the circular movement or centrifugal force, where it emerges from the impeller IMP and reaches a diffuser DIF.
  • the impeller IMP has a wheel disc HWH, on which blades BLD are attached.
  • the blades BLD delimit individual flow channels FTH of the impeller IMP in the circumferential direction CDR.
  • flow channels FTH are delimited radially outwards by means of a flow contour FCR of the standing contour ring COR with the interposition of a running clearance GAP.
  • a flow contour FCR of the standing contour ring COR with the interposition of a running clearance GAP.
  • the impeller IMP according to the embodiment that in the Figures 1 - 4 shown is a so-called open impeller IMP without a cover plate.
  • the individual flow channels FTH are delimited radially outwards by a cover disk, which lies essentially radially opposite the wheel disk HWH.
  • the limitation of the individual flow channels FTH due to the flow contour FCR of the contour ring COR is increasingly axial instead of radial.
  • the standing contour ring COR deflects the process fluid PFL, which axially enters the impeller IMP, from an axial flow direction into a radial flow direction.
  • the arrangement of the impeller IMP and the standing contour ring COR is surrounded by a housing CAS, which, as a pressure vessel, also encapsulates the internal pressure in the RTM radial turbomachine from the ambient pressure.
  • the contour ring COR has distribution channels DSC below the surface SRF, which are fluidly connected to a supply unit SPU for a cleaning agent DTG. If necessary, the supply unit SPU is controlled such that the cleaning agent DTG flows into the supply channels DSC, which form a supply network, and reaches the surface SRF of the contour ring COR there.
  • the cleaning agent DTG is preferably an oily liquid (for example a so-called washing oil), which prevents or even detaches any buildup from the process fluid PFL on the contour ring COR or on the flow contour FCR.
  • the liquid or gaseous cleaning agent DTG flows out of the supply channels DSC through the permeable surface SRF.
  • the permeable surface SRF is particularly preferred as a coating COT of a base body BBD of the contour ring COR, as in Figure 2 shown, trained.
  • the coating COT can have an open porosity and can therefore be permeable to the cleaning agent DTG.
  • the distribution channels DSC are particularly preferably divided into different fluid-conducting distribution channel groups DSCG.
  • the distribution channel groups DSCG can each have their own inlet DI1, DI2 and their own outlet DE1, DE2.
  • the first inlet DI1 which in Figure 4 is shown, enables a flow of the cleaning agent DTG through the corresponding system of the supply channels DSC of a distribution line DSN up to the first supply process DE1, driven only by the force of gravity g.
  • Another supply of the distribution line DSN which does not operate by means of gravity, is ensured by means of the second inlet DI1 and second outlet DE2.
  • the contour ring COR is at least slightly cleaned by means of the cleaning agent DTG along the distribution path DSN from the first inlet DI1 to the first outlet DE1 with the release of the cleaning agent that flows through the flow contour FCR permeable surface achieved.
  • the amount of cleaning agent DTG flowing off through the process DE1, DE2 is reduced by the amount that emerges from the contour ring COR.
  • this portion of the cleaning agent DTG is distributed in the circumferential direction CDR and at least temporarily prevents the build-up on the contour ring COR.
  • the Figures 2 and 3 show in addition to the distribution of a cleaning agent DTG according to the invention, in particular during the operation of the radial turbomachine RTM, additionally a cooling device COS of the contour ring COR.
  • the contour ring COR can be thermally checked by means of the cooling device COS, so that temperatures that are too high or too low do not occur.
  • the contour ring COR here has cooling channels CLC of the cooling device COS, through which a coolant CLM flows.
  • the coolant CLM be identical to the cleaning agent DTG.
  • cooling channels CLC are at least partially connected to the distribution channels DSC in such a way that there is fluid at least unidirectional access or exchange between the cooling device COS and the distribution channels DSC.
  • This training is in Figure 3 shown schematically.
  • contour ring extends in the Figure 1 only in the area of the open impeller IMP.
  • the contour ring can also continue to extend in the downstream direction, for example into the diffuser DIF.
  • contour ring COR is therefore not to be understood according to the invention exclusively in such a way that only the area directly opposite the open impeller IMP is occupied by the contour ring COR.
  • the permeable surface of the contour ring can also be produced using additive manufacturing. It is particularly preferred that at least some of the contour ring COR and / or at least some of the distribution channels DSC below the surface SRF and / or at least some of the surface SRF can be produced by means of additive manufacturing.
  • the invention also includes a method for operating the radial turbomachine RTM, the radial turbomachine RTM with the contour ring COR being put into operation and during the compression or expansion of the process fluid PFL the supply unit SPU is controlled in a second step such that the cleaning agent DTG is activated by the permeable surface SRF is promoted during the operation of the compressor CP in the area of the running play GAP.
