Description

Die Erfindung betrifft einen mehrstufigen Turbokompressor, der als Getriebekompressor mit einem integrierten Getriebe ausgelegt ist, mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a multi-stage turbocompressor, which is designed as a transmission compressor with an integrated transmission, with the features of the preamble of claim 1.

Bekannte Getriebekompressoren ( DE 974 418 , EP 0 440 902 B1 , EP 1 302 668 A1 ) sind durch ein Großrad gekennzeichnet, das mit mehreren Ritzeln in Eingriff steht. Auf den Ritzeln sind jeweils ein oder zwei Kompressorstufen befestigt. Die Ritzel umgeben das Großrad, das direkt angetrieben wird, indem die Welle des Großrades mit der Antriebswelle gekoppelt ist. Eine andere Möglichkeit der Ankopplung des Antriebsaggregates an den Getriebekompressor kann über ein Antriebsritzel erfolgen, das ebenso wie die Ritzel der Kompressorstufen mit dem Großrad in Eingriff steht. Bedingt durch den Aufbau eines Getriebekompressors wird das Antriebsritzel unterhalb des Großrades angeordnet. Ein derartiger Getriebekompressor erfordert einen Höhenversatz in der Aufstellung, da die Welle des Großrades und die Welle des Antriebsaggregates um einen Betrag auseinander liegen, der sich aus der Summe aus dem Radius des Großrades und dem Radius des Antriebsaggregates ergibt. Dadurch wird ein zusätzlicher Bauraum benötigt.Known transmission compressors ( DE 974 418 . EP 0 440 902 B1 . EP 1 302 668 A1 ) are characterized by a large wheel, which is engaged with a plurality of pinions. On the pinions one or two compressor stages are attached. The pinions surround the large gear, which is directly driven by the shaft of the large gear is coupled to the drive shaft. Another way of coupling the drive unit to the gear compressor can be done via a drive pinion, which is like the pinion of the compressor stages with the Großrad engaged. Due to the structure of a transmission compressor, the drive pinion is arranged below the large wheel. Such a transmission compressor requires a height offset in the lineup, since the shaft of the large gear and the shaft of the drive unit are apart by an amount that results from the sum of the radius of the large gear and the radius of the drive unit. This requires additional space.

Aus der DE 24 13 674 A1 ist ein gattungsgemäßer radialer mehrstufiger Turboverdichter 10 bekannt, der als Getriebekompressor mit einem integrierten Getriebe ausgelegt ist. Das Getriebe weist ein Getriebegehäuse 14 auf, das von einer Innenwand 22 und einer Außenwand oder Abdeckplatte 24 begrenzt ist. Innerhalb der Wände des Getriebegehäuses 14 befindet sich ein Antriebsrad 26 mit einem Rad 30 eines ersten Kompressorgehäuses 16 und mit einem Leerlaufrad 28 in Eingriff. Dabei sind das Antriebsrad 26 mit dem Rad 30 des ersten Kompressorgehäuses 16 und mit dem Leerlaufrad 28 in einer schrägen Ebene angeordnet. Das Leerlaufrad 28 befindet sich mit Rädern 32 und 32' eines zweiten bzw. dritten Kompressorgehäuses 18 bzw. 20 in Eingriff. Das Antriebsrad 26 ist auf einer Welle 34 befestigt, die ein Anschlussende 36 aufweist, das aus der Außenwand oder Abdeckplatte 24 hervorsteht. An das Anschlussende 36 kann eine Antriebseinheit angeschlossen werden, um ein antreibendes Drehmoment auf die verschiedenen Räder zu übertragen.From the DE 24 13 674 A1 a generic radial multi-stage turbocompressor 10 is known, which is designed as a transmission compressor with an integrated transmission. The transmission has a transmission housing 14, which is bounded by an inner wall 22 and an outer wall or cover plate 24. Within the walls of the transmission housing 14 is a drive wheel 26 with a wheel 30 of a first Compressor housing 16 and with an idler 28 in engagement. In this case, the drive wheel 26 are arranged with the wheel 30 of the first compressor housing 16 and with the idler 28 in an oblique plane. The idler 28 is engaged with wheels 32 and 32 'of second and third compressor housings 18 and 20, respectively. The drive wheel 26 is mounted on a shaft 34 having a terminal end 36 protruding from the outer wall or cover plate 24. To the terminal end 36, a drive unit can be connected to transmit a driving torque to the various wheels.

Aus der GB 967 091 ist ein dreistufiger Radialkompressor bekannt, bei dem ein Ritzel von den drei Ritzeln 32 oder 33 oder 34 der Kompressorstufen als Antrieb durch eine Dampfturbine 30 dient. Um einen kompakten Aufbau der Dampfturbine mit kleinsten Abmessungen zu erreichen, liegt der wesentliche Vorteil einer solchen Anordnung darin, dass die Dampfturbine eine geeignete Verbindung mit einer der vorhandenen Ritzelwellen erlaubt, deren vorgesehene Umlaufgeschwindigkeit am besten mit der Umlaufgeschwindigkeit der Welle des Rotors der Dampfturbine zusammenpasst.From the GB 967,091 a three-stage radial compressor is known in which a pinion of the three pinions 32 or 33 or 34 of the compressor stages serves as a drive through a steam turbine 30. In order to achieve a compact design of the steam turbine with the smallest dimensions, the main advantage of such an arrangement is that the steam turbine allows a suitable connection with one of the existing pinion shafts whose intended rotational speed best matches the rotational speed of the shaft of the rotor of the steam turbine.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, einen mehrstufigen Turbokompressor mit einem integrierten Getriebe so zu gestalten, dass eine raumsparende Anordnung eines aus mindestens einem Turbokompressor und Antriebsaggregat bestehenden Maschinenstranges erreicht wird, der keinen Höhenversatz aufweist und vielseitig zu verwenden ist.The problem underlying the invention is to design a multi-stage turbocompressor with an integrated transmission so that a space-saving arrangement of an existing from at least one turbo compressor and drive unit engine line is achieved, which has no vertical offset and is versatile to use.

Die Aufgabe wird bei einem gattungsgemäßen Turbokompressor mit integriertem Getriebe erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.The object is in a generic turbocompressor with integrated transmission according to the invention by the characterizing Characteristics of claim 1 solved. Advantageous embodiments of the invention are the subject of the dependent claims.

Mit Hilfe des erfindungsgemäß gestalteten mehrstufigen Turbokompressors lässt sich ein Maschinenstrang aufbauen, in dem für den Turbokompressor und das Antriebsaggregat eine gemeinsame Mittelebene vorhanden ist. Wird dieser Maschinenstrang durch weitere Aggregate, wie beispielsweise einen Motor/Generator und/oder einen Expander erweitert, so besteht die gemeinsame Mittelebene auch für die zusätzlichen Aggregate. Durch die gemeinsame Mittelebene wird ein Höhenversatz im dem Grundrahmen, auf dem die Aggregate aufgestellt sind, sowie in dem Fundamenttisch (Stahlgerüst oder Beton) des Maschinenstranges vermieden. Das umbaute Volumen des Maschinenstranges wird geringer, wodurch die Herstellung, der Transport, der Betrieb und die Wartung des Maschinenstranges einfacher und kostengünstiger werden. Der Bau von größeren Kompressoren wird möglich, da der für die Kompressorgehäuse notwendige Platz vergrößert wird. Schließlich wird die mechanische Belastung einzelner Bauteile, wie das Antriebsritzel, die Lager und das Getriebegehäuse reduziert.With the help of the inventively designed multi-stage turbo compressor can build a machine train in which a common center plane is present for the turbo compressor and the drive unit. If this machine train is extended by further units, such as a motor / generator and / or an expander, the common center plane also exists for the additional units. Due to the common center plane, a height offset in the base frame, on which the units are installed, as well as in the foundation table (steel frame or concrete) of the machine string is avoided. The reduced volume of the machine train is reduced, making the manufacture, transport, operation and maintenance of the machine train easier and less expensive. The construction of larger compressors becomes possible because the space required for the compressor housings is increased. Finally, the mechanical stress on individual components, such as the drive pinion, the bearings and the gear housing is reduced.

Unterhalb des Maschinentisches 5 befinden sich mehrere Kühler, ein Kondensator und weitere für den Betrieb der Anlage notwendige Apparate.The in Fig. 1 The machine train shown is part of a chemical plant for the treatment and further processing of gases. Such a machine train consists of a Drive unit 1 and a gear compressor 2. Depending on the type of chemical plant, the machine train may include a motor / generator 3 and an expander 4. The individual units are coupled together and mounted on a base frame, the machine table 5, which rests on a concrete or steel foundation. Below the machine table 5 are several coolers, a condenser and more necessary for the operation of the system apparatuses.

Das Antriebsaggregat 1 ist vorzugsweise als Dampfturbine ausgebildet, deren Abtriebswelle mit der Antriebswelle 6 des nachfolgenden Getriebekompressors 2 verbunden ist. Der Getriebekompressor 2 ist ein mehrstufiger Turbokompressor mit integriertem Getriebe und dient zur Verdichtung eines Gases.The drive unit 1 is preferably designed as a steam turbine whose output shaft is connected to the drive shaft 6 of the subsequent transmission compressor 2. The transmission compressor 2 is a multi-stage turbocompressor with integrated transmission and serves to compress a gas.

Der Getriebekompressor 2 nach Fig. 3 umfasst ein Gehäuse 7, in dem ein Antriebsritzel 8, ein Großrad 9 und weitere Ritzel 10, 14, 15 angeordnet sind. Das Antriebsritzel 8 ist auf der Antriebswelle 6 befestigt, die in dem Gehäuse 7 des Getriebekompressors 2 gelagert ist. Das Antriebsritzel 8 steht auf einer Seite mit einem ersten Ritzel 10 in Eingriff, das auf einer ersten Ritzelwelle 11 drehfest befestigt ist. Die erste Ritzelwelle 11 trägt auf ihrem einen Ende ein Laufrad, das in dem Spiralgehäuse 12 eines Kompressors umläuft, der die erste Kompressorstufe I des mehrstufigen Getriebekompressors 2 darstellt.The transmission compressor 2 after Fig. 3 comprises a housing 7, in which a drive pinion 8, a large gear 9 and further pinions 10, 14, 15 are arranged. The drive pinion 8 is mounted on the drive shaft 6, which is mounted in the housing 7 of the transmission compressor 2. The drive pinion 8 engages on one side with a first pinion 10 which is rotatably mounted on a first pinion shaft 11. The first pinion shaft 11 carries on its one end an impeller which rotates in the volute casing 12 of a compressor constituting the first compressor stage I of the multistage transmission compressor 2.

Das Antriebsritzel 8 steht auf der dem ersten Ritzel 10 abgewandten Seite mit dem Großrad 9 in Eingriff, das auf einer in dem Gehäuse 7 gelagerten Welle 13 drehfest befestigt ist. Die über das Antriebsritzel 8 eingeleitete Leistung des Antriebsaggregates 1 wird gleichzeitig an das Großrad 9 und das erste, zu der ersten Kompressorstufe I gehörende Ritzel 10 abgegeben.The drive pinion 8 is on the side facing away from the first pinion 10 side with the large gear 9 into engagement, which is rotatably mounted on a shaft 13 mounted in the housing. The introduced via the drive pinion 8 power of the drive unit 1 is delivered simultaneously to the large gear 9 and the first, belonging to the first compressor stage I pinion 10.

Das Großrad 9 steht mit einem zweiten Ritzel 14 und einem dritten Ritzel 15 in Eingriff, die jeweils auf einer zweiten und einer dritten in dem Gehäuse 7 gelagerten Ritzelwelle 16, 17 drehfest befestigt sind. Die zweite Ritzelwelle 16 trägt an ihren Enden die Laufräder einer zweiten und einer dritten Kompressorstufe II, III. Die dritte Ritzelwelle 17 trägt an ihren Enden die Laufräder einer vierten und einer fünften Kompressorstufe IV, V mit den Spiralgehäusen 18, 19. Alle Kompressorstufen sind auf den entsprechenden Ritzelwellen fliegend gelagert.The large gear 9 is connected to a second pinion 14 and a third pinion 15 into engagement, which are respectively rotatably mounted on a second and a third mounted in the housing 7 pinion shaft 16, 17. The second pinion shaft 16 carries at its ends the wheels of a second and a third compressor stage II, III. The third pinion shaft 17 carries at its ends the wheels of a fourth and a fifth compressor stage IV, V with the volute casings 18, 19. All compressor stages are cantilevered on the corresponding pinion shafts.

Die Antriebswelle 6, die erste Ritzelwelle 11, die zweite Ritzelwelle 16 und die Welle 13 des Großrades 9 liegen in derselben horizontalen Ebene 20. Die dritte Ritzelwelle 17 liegt oberhalb dieser Ebene 20. In der Darstellung der Fig. 3 befindet sich in Bezug auf das Großrad 9 das Antriebsritzel 8 in der 9-Uhr-Stellung, das zweite Ritzel 14 in der 3-Uhr-Stellung und das dritte Ritzel 15 in der 12-Uhr-Stellung. In Bezug auf das Antriebsritzel 8 befindet sich das erste Ritzel 10 in der 9-Uhr-Stellung und das Großrad 9 in der 3-Uhr Stellung.The drive shaft 6, the first pinion shaft 11, the second pinion shaft 16 and the shaft 13 of the large wheel 9 are in the same horizontal plane 20. The third pinion shaft 17 is above this level 20. In the illustration of Fig. 3 is located in relation to the large gear 9, the drive pinion 8 in the 9 o'clock position, the second pinion 14 in the 3 o'clock position and the third pinion 15 in the 12 o'clock position. With respect to the drive sprocket 8, the first sprocket 10 is in the 9 o'clock position and the large gear 9 is in the 3 o'clock position.

Das Kernstück des Maschinenstranges sind der Getriebekompressor 2 und die Dampfturbine als Antriebsaggregat 1. Der Motor/Generator 3 und der Expander 4 sind Komponenten, die je nach der Art des chemischen Prozesses zusammen oder einzeln auch weggelassen werden können. Ist ein Motor/Generator 3 installiert, so wird er entweder direkt oder über ein Getriebe mit der Welle 13 des Großrades 9 verbunden.The core of the machine train are the geared compressor 2 and the steam turbine as the drive unit 1. The motor / generator 3 and the expander 4 are components that can be omitted together or individually depending on the nature of the chemical process. If a motor / generator 3 is installed, it is connected either directly or via a gear to the shaft 13 of the large gear 9.

Der Maschinenstrang kann mit der Dampfturbine als Antriebsaggregat 1 gestartet werden, sofern Dampf vorhanden ist. Der Motor (Motor/Generator 3 in Motorschaltung) übernimmt dann den Antrieb des Maschinenstranges ab der Synchrondrehzahl des Motors. Der Expander 4 gibt erst Leistung ab, wenn der chemische Prozess in Gang gekommen ist und das Abgas oder der Abdampf aus dem Prozess den Expander 4 antreibt. Der Expander 4 kann auch mit Luft betrieben werden, die der Getriebekompressor 2 verdichtet hat, so dass ein Teil der Energie zurückgewonnen werden kann.The machine train can be started with the steam turbine as the drive unit 1, if steam is available. The motor (motor / generator 3 in motor circuit) then takes over the drive of the machine train from the synchronous speed of the engine Engine. The expander 4 delivers power only when the chemical process has started and the exhaust gas or exhaust steam from the process drives the expander 4. The expander 4 can also be operated with air, which the transmission compressor 2 has compressed, so that a part of the energy can be recovered.

Der Maschinenstrang kann auch mit dem Motor (Motor/Generator 3 in Motorschaltung) gestartet werden. Wenn infolge des ablaufenden chemischen Prozesses nach dem Start erst einmal Dampf erzeugt wird, dann treibt die Dampfturbine als Antriebsaggregat 1 den Maschinenstrang weiter an.The machine train can also be started with the motor (motor / generator 3 in motor circuit). If steam is generated as a result of the running chemical process after the start, then drives the steam turbine drive unit 1 as the machine strand on.

Fehlt der Expander 4, und ist nur ein Generator (Motor/Generator 3 in Generatorschaltung) installiert, dann gibt die Dampfturbine als Antriebsaggregat 1 soviel Leistung ab, dass der Getriebekompressor 2 betrieben und die Zusatzleistung als elektrische Energie vom Generator ins Netz eingespeist werden kann.If the expander 4 is missing, and if only one generator (motor / generator 3 in generator circuit) is installed, then the steam turbine as drive unit 1 delivers so much power that the geared compressor 2 is operated and the additional power can be fed as electrical energy from the generator into the grid.
