Description

COMPRESSOR COMPRISING A GUIDE VANE HAVING A WASHING
SYSTEM
The invention relates to a compressor according to the preamble of claim 1.
From practice, the fundamental construction of a compressor serving for compressing a working medium is thoroughly known. Accordingly, a compressor comprises at least one rotor side rotor-blade ring with a plurality of rotor blades and at least one stator side guide-vane ring with a plurality of guide vanes.
Accordingly, DE 10 2010 064 047 Al shows a turbo machine with a radial compressor and a radial turbine, wherein the compressor comprises a rotor-blade ring and a guide-vane ring, wherein the guide-vane ring is described as initial guide vane device.
The guide vanes of a guide-vane ring can be embodied adjustably. Accordingly, an adjusting device of the guide vanes of a guide-vane ring of an axial turbo machine is known for example from DE 37 11 224 C2.
It is known that a compressor can comprise a washing device in order to be able to wash or clean the assemblies of the compressor. Such washing devices according to the practice are additional installations in the compressor. So as not to negatively affect the through-flow and thus the efficiency of the compressor too greatly, these additional installations are positioned with a clear distance to the assemblies of the compressor to be cleaned, in particular with distance to the rotor blades of a rotor-blade ring to be cleaned, as a result of which the cleaning effect is negatively affected.
2 There is therefore a need for a compressor the assemblies of which can be cleaned better or more effectively, namely without the risk that the through-flow and thus the efficiency of the compressor are negatively affected because of this.
Starting out from this, the present invention is based on the object of creating a new type of compressor.
This object is solved through a compressor according to claim 1. In the region of at least one guide-vane ring, at least one guide vane of the same comprises a washing system, via which washing agent is squirtable or squirtable or sprayable onto the assemblies positioned adjacent to the respective guide-vane ring, in particular onto the rotor-blade ring positioned adjacent to the respective guide-vane ring. The guide vanes can be fixed or adjustable.
With the present invention it is proposed that at least one guide vane of at least one guide-vane ring of a compressor according to the invention comprises a washing system, via which washing agent is squirtable onto the assemblies positioned in each case adjacent to the respective guide-vane ring, in particular onto a rotor-blade ring positioned adjacent to the respective guide-vane ring. Accordingly, the washing system is integrated in at least one guide vane of the respective guide-vane ring. No additional installations are present in the compressor which could negatively affect the flow through the compressor and thus the efficiency of the same. Furthermore, the washing system is positioned adjacent to the assemblies to be cleaned, so that the same are reliably and effectively squirtable with washing agent from the washing system. This allows an effective cleaning of the assemblies of the compressor to be cleaned.
3 According to an advantageous further development of the invention, a plurality of guide vanes in the region of at least one guide-vane ring comprise a washing system, wherein the number and position of the guide vanes in the respective guide-vane ring having a washing system is designed so that the assemblies that are squirtable or sprayable via the washing system of the respective guide-vane ring, in particular of the rotor-blade ring positioned adjacent to the respective guide-vane ring that are squirtable or sprayable by the same, is or are not excitable into natural vibrations by the squirting or spraying with the washing agent. With this advantageous further development of the invention it can be ensured that the assemblies of the compressor to be cleaned are not excited into natural vibrations by the washing process.
According to an advantageous further development of the invention, the washing system of the respective guide vane comprises at least one nozzle and at least one washing agent duct leading to the respective nozzle, wherein the or each washing agent duct runs within the respective guide vane. The or each washing agent duct of the respective guide vane is suppliable with the washing agent via a supply duct introduced into a vane root or into a driving pin of the respective guide vane. This allows a particularly advantageous integration of a washing system in a guide vane of a guide-vane ring and the supply of the or each nozzle of the washing system with washing agent starting out from the vane root or driving pin of the respective guide vane. The aforementioned arrangement is advantageous for particularly adjustable guide vanes.
Preferentially, the or each guide vane having a washing system is produced via an additive production method.
4 This allows a particularly advantageous integration of the washing system in the respective guide vane.
Preferred further developments of the invention are obtained from the subclaims and the following description. Exemplary embodiments of the invention are explained in more detail by way of the drawing without being restricted to this. It shows:
Fig. 1: a diagram of a compressor; and Fig. 2: a guide vane of a compressor according to the invention.
The present invention relates to a compressor. The compressor can be an axial compressor or a radial compressor. Such a compressor comprises at least one rotor side rotor-blade ring with a plurality of rotor blades and at least one stator side guide-vane ring with a plurality of guide vanes.
Fig. 1 shows exemplarily in a highly schematic manner a compressor 10 designed as axial compressor, which serves for compressing a working medium 11.
In the shown exemplary embodiment, the compressor 10 comprises rotor-blade rings 12, 13 each with a plurality of rotor blades 12a, 13a, which rotate together with a shaft 14. Seen in flow direction of the working medium 11, a guide-vane ring 14 and 16 respectively is positioned in each case upstream of each rotor-blade ring 12, 13, whe/ein each of the guide-vane rings 15, 16 has a plurality of guide vanes 15a and 16a respectively. The guide vanes 15a, 16a or the guide-vane rings 15, 16 are stationary assemblies, which like a housing 17 of the compressor do not rotate but can be moveable or adjustable.

It is pointed out here that the compressor 10 designed as axial compressor and shown in Fig. 1 is purely exemplary in nature. The invention can also be employed with radial compressors. Furthermore, the number of the shown guide-vane rings and rotor-blade rings is purely exemplary in nature.
According to the invention, at least one guide vane 15a, 16a of the respective guide-vane ring 15, 16 in the region of at least one guide-vane ring 15, 16 comprises a washing system 18, which is an integral part of the guide vane 15a, 16a. Via this washing system 18, which is part of a guide vane 15a, 16a, washing agent is squirtable or sprayable onto the assemblies of the compressor positioned adjacent to the respective guide vane 15, 16, in particular onto a rotor-blade ring 12, 13 positioned adjacent to the respective guide-vane ring 15, 16, in order to clean the respective assembly.
Fig. 2 shows schematically a guide vane 15a and 16a of a guide-vane ring 15 and 16 respectively of the compressor 10, which comprises a washing system 18 integrated in the guide vane 15a, 16a, wherein the washing system 18 of the guide vane 15a, 16a of Fig. 2 comprises at least one preferentially more nozzle 19 or nozzles 19 integrated in the guide vane 15a, 16a which serve for squirting or spraying an assembly to be cleaned positioned adjacent to the respective guide-vane ring 15, 16. A washing agent duct 20 integrated in the guide vane 15a, 16a, via which the respective nozzle 19 can be supplied with washing agent, interacts with each nozzle 19. The washing agent ducts 20 leading to the nozzles 19 are suppliable with washing agent via a supply channel 22 introduced into or integrated in a vane root 21 or in a driving pin 21 of the respective guide vane 15a, 16a.
The supply via the driving pin 21 or vane root 21 is predominantly effected with adjustable guide vanes 15a, 16a.
The plurality of nozzles 19 of the respective guide vane 15a, 16a are distributed over the height of the respective guide vane 15a, 16a which extends transversely to the flow direction through the respective guide vane ring 15, 16, preferentially evenly distributed or positioned so that they optimally spray the rotor blades.
Position and spray angle of the nozzles 19 of the respective guide vane 15a, 15b are preferentially designed for an optimal cleaning of the respective assemblies of the compressor 10 to be cleaned.
The respective guide vane 15a, 16a can be an adjustable guide vane 15a, 16a of a guide-vane ring designed for example as adjustable initial guide vane ring. In this case, the vane root 21 is designed as driving pin in order to adapt the relative position of the respective guide vane 15a, 16a in the flow duct of the compressor and thus the inflow of the rotor-blade ring 12, 13 positioned downstream of the respective guide-vane ring 15, 16.
The supply channel 22 of the respective guide vane 15a, 16a introduced into the vane root or driving pin can be supplied with the washing agent via a flexible supply hose, in the case of an adjustable guide-vane ring alternatively via a driveshaft of the guide-vane ring, which serves for adjusting the guide vanes of the respective guide-vane ring.

It is therefore in the interest of the present invention that at least one guide vane 15a, 16a of at least one guide-vane ring 15, 16 of a compressor has a washing system 18 integrated in the same, via which washing agent is squirtable or sprayable onto assemblies positioned to the respective guide-vane ring 15, 16, in particular onto a rotor-blade ring 12, 13 positioned adjacent to the respective guide-vane ring 15, 16.
Since a rotor-blade ring 12, 13 during the operation rotates relative to the fixed guide-vane ring 15, 16 it is adequate when a single guide vane of the guide-vane - ring comprises a washing system 18, since via the rotation of the rotor-blade ring the rotor blades 12a, 13a of the same are moved past the respective guide vane 15a, 16a, which comprises the washing system 18, so that the adjacent rotor-blade ring can be completely sprayed or squirted with washing agent and thus cleaned even via the washing system 18 of a single guide vane.
According to an advantageous further development it is possible that a plurality of guide vanes 15a, 16a, preferentially in the region of at least one guide-vane ring 15, 16, each have a washing system 18. The number and position of the guide vanes 15a, 16a having such a washing system 18 is designed or selected in such a manner that the assemblies that are squirtable or sprayable via the washing systems 18 of the respective guide vanes 15a, 16a of the respective guide-vane ring 15 and 16 respectively, in particular the rotor-blade ring 12 and 13 respectively which is positioned adjacent to the respective guide-vane ring 15a, 16a and is squirtable or sprayable from the same is not excitable into natural vibrations by the squirting or spraying with the washing agent.

This then makes possible a particularly advantageous cleaning of the compressor without the risk of a vibration excitation of the respective assemblies to be cleaned, in particular of the respective rotor-blade ring to be cleaned.
As already explained, the nozzles 19 and the washing agent duct 20 are an integral part of the respective guide vane 15a and 16a respectively. Here it can be provided that the respective guide vane 15a and 16a respectively is produced by an additive production method. Additive production methods are also described as generative production methods, these include for example selective laser melting or selective laser sintering. Via such an additive or generative production method, a guide vane 15a, 16a can be particularly advantageously produced with integrated washing system 18.
In contrast with this it is also possible, however, that the guide vane 15a, 16a, comprising a washing system 18, is produced as a casting. Here, the washing agent ducts 20 as well as nozzle 19 can already be formed during the casting. Furthermore it is possible to subsequently introduce the nozzles 19 and ducts 20 into the respective guide vane 15a, 16a after the casting.
The compressor according to the invention makes possible an effective cleaning of assemblies of the same without the need of additional installations, which negatively affect the flow through the compressor. At least one guide vane of a guide-vane ring comprises a washing system which is an integral part of the respective guide vane. By way of this, rotor blades of a rotor-blade ring in particular positioned directly adjacent to the respective guide-vane ring can be effectively cleaned.
