  Preferred further developments of the invention emerge from the dependent claims and the following description. Examples of the present invention will be described in more detail with reference to the drawings, but are not limited thereto. The following figure is shown.

It is the schematic of a compressor. It is a figure which shows the guide vane of the compressor which concerns on this invention.

  The present invention relates to a compressor. The compressor can be an axial compressor or a centrifugal compressor. Such a compressor has 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 very schematically illustrates a compressor 10 configured as an axial compressor used to compress a working medium 11.

  In the illustrated embodiment, the compressor 10 has rotor blade rings 12, 13 each having a plurality of rotor blades 12 a, 13 a that rotate with the shaft 14. When viewed in the direction in which the working medium 11 flows, guide vane rings 15 and 16 are respectively arranged upstream of the rotor blade rings 12 and 13, and each of the guide vane rings 15 and 16 includes a plurality of guide vanes 15a and 15a. 16a. The guide vanes 15a, 16a or the guide vane rings 15, 16 are stationary assemblies and, like the compressor housing 17, do not rotate but may be movable or adjustable.

  It should be pointed out that the compressor 10 configured as an axial compressor shown in FIG. 1 is purely exemplary in nature. The present invention can also be used in a centrifugal compressor. Furthermore, the number of guide vane rings and rotor blade rings shown are merely exemplary in nature.

  According to the invention, in the region of at least one guide vane ring 15, 16, at least one guide vane 15 a, 16 a of each of the guide vane rings 15, 16 has a cleaning system 18, Each of the guide vanes 15a and 16a is an integral component. The compressor assembly disposed adjacent to each of the guide vane rings 15, 16 through the cleaning system 18 that is a component of the guide vanes 15 a, 16 a, particularly the rotor disposed adjacent to each of the guide vane rings 15, 16. A cleaning agent can be sprayed or sprayed onto the blade rings 12, 13 so that each assembly is cleaned.

  FIG. 2 schematically shows the guide vanes 15a and 16a of the guide vane rings 15 and 16 of the compressor 10, respectively. The guide vane rings 15 and 16 include a cleaning system 18 incorporated in the guide vanes 15a and 16a. The cleaning system 18 of the guide vanes 15a, 16a of FIG. 2 includes at least one, preferably a plurality of nozzles 19 incorporated in the guide vanes 15a, 16a. 16 used to spray or spray the assembly to be cleaned located adjacent to each other. A cleaning agent conduit 20 incorporated in the guide vanes 15a, 16a cooperates with each nozzle 19, and each nozzle 19 can be supplied with a cleaning agent through the cleaning agent conduit 20. The cleaning agent conduit 20 leading to the nozzle 19 may be supplied with cleaning agent through a supply channel 22 introduced or incorporated into the vane base 21 or drive pin 21 of each guide vane 15a, 16a.

  The supply through the drive pin 21 or the vane base 21 takes place mainly in the adjustable guide vanes 15a, 16a.

  The plurality of nozzles 19 of each of the guide vanes 15a, 16a are distributed over a height extending in a direction transverse to the flow direction of each of the guide vane rings 15, 16 of each of the guide vanes 15a, 16a, preferably It is evenly distributed or arranged so that the rotor blades are optimally sprayed.

  The nozzle 19 position and spray angle of each of the guide vanes 15a, 16a are preferably designed to allow optimal cleaning of each of the assemblies of the compressor 10 to be cleaned.

  In this case, each of the guide vanes 15a, 16a may be an adjustable guide vane 15a, 16a of a guide vane ring configured, for example, as an adjustable inlet guide vane ring. In this case, the vane base 21 is configured as a drive pin, and is thereby disposed in the flow path of the compressor 10 in the relative position of each of the guide vanes 15a and 16a, and thus downstream of each of the guide vane rings 15 and 16. The inflow of the rotor blade rings 12, 13 is adapted.

  The supply channel 22 of each of the guide vanes 15a, 16a introduced into the vane base or drive pin can be supplied with a cleaning agent through a flexible supply hose, but in the case of an adjustable guide vane ring, Alternatively, it can be supplied through the drive shaft of the guide vane ring used to adjust the guide vane of each guide vane ring.

  Since the rotor blade rings 12, 13 rotate relative to the fixed guide vane rings 15, 16 during operation, it is sufficient that one guide vane of the guide vane ring has a cleaning system 18. This is because the rotation of the rotor blade ring causes all rotor blades 12a, 13a of the rotor blade ring to pass close to each of the guide vanes 15a, 16a having the cleaning system 18, so that even with one guide vane cleaning system 18 This is because the adjacent rotor blade rings can be completely sprayed or sprayed with a cleaning agent and thereby cleaned evenly.

  According to an advantageous further development, a plurality of guide vanes 15a, 16a can each have a cleaning system 18, preferably in the region of at least one guide vane ring 15, 16. The number and position of the guide vanes 15a, 16a having such a cleaning system 18 is determined by the assembly, in particular the guide vane ring 15a, that can be sprayed or sprayed through the cleaning system 18 of each of the guide vanes 15 and 16, respectively. The rotor blade ring 12 or 13 arranged adjacent to each of the 16a and capable of being sprayed or sprayed from the guide vane ring is designed or selected such that it cannot be excited to the natural vibration by spraying or spraying the cleaning agent. Yes.

  Thereby, a particularly advantageous cleaning of the compressor is possible without the risk of vibration excitation of each assembly to be cleaned, in particular vibration excitation of each rotor blade ring to be cleaned.

  As already mentioned, the nozzle 19 and the cleaning agent conduit 20 are integral components of the guide vanes 15a and 16a, respectively. At that time, it is possible to define that each of the guide vanes 15a and 16a is manufactured by an additional manufacturing method. Additional manufacturing methods are also called generative manufacturing methods, such as selective laser melting or selective laser sintering. Through such an additional or productive manufacturing method, the guide vanes 15a, 16a with an integral cleaning system 18 can be manufactured particularly advantageously.

  However, it is also possible to produce the guide vanes 15a, 16a having the cleaning system 18 as castings. In this case, the cleaning agent conduit 20 and the nozzle 19 can already be formed during casting. Further, the nozzle 19 and the conduit 20 can be introduced later into the guide vanes 15a and 16a after casting.

  The compressor according to the invention allows an effective cleaning of the assembly. In this case, no additional equipment for hindering the flow of the compressor is required. At least one guide vane of the guide vane ring has a cleaning system that is an integral component of each guide vane. Thereby, the rotor blades, which are arranged directly adjacent to each of the guide vane rings, in particular of the rotor blade ring, are effectively cleaned.
