Aus der WO 2011/141439 A1 ist bereits eine Anordnung mit einem mehrstufigen Getriebeverdichter insbesondere zur Luftzerlegung bekannt. Bei einem derartigen Kompressor-Strang einer Luftverdichtungsanlage für eine Luftzerlegung werden sehr viele mechanische Komponenten, beispielsweise Getriebegehäuse mit Getriebeelementen und Kupplungen, etc. verwendet. Diese Bauteile dienen häufig nicht unmittelbar dem Zweck der Druckerhöhung eines Volumenstroms an Luft. Stattdessen sind diese Elemente notwendig, die eigentliche konstruktive Lösung zu realisieren, insbesondere, die einzelnen Verdichter mit einer geeigneten Drehzahl zu betreiben. Viele dieser Bauteile erzeugen neben hohen Investitionskosten auch insbesondere mechanische Verlustleistungen, die in Form von Wärme abgeführt werden, muss. Dementsprechend sind in der Regel großvolumige Ölanlagen zur Schmierung von Lagern und auch zur Kühlung des Getriebeöls erforderlich.From the WO 2011/141439 A1 an arrangement with a multi-stage geared compressor, in particular for air separation, is already known. A large number of mechanical components, for example gear housings with gear elements and clutches, etc., are used in such a compressor train of an air compression system for air separation. These components often do not directly serve the purpose of increasing the pressure of a volume flow of air. Instead, these elements are necessary to implement the actual design solution, in particular to operate the individual compressors at a suitable speed. In addition to high investment costs, many of these components also generate mechanical power losses, which must be dissipated in the form of heat. Accordingly, large-volume oil systems are usually required to lubricate bearings and also to cool the gear oil.

Es ist bekannt, Luftzerlegungsanlagen mit zwei Getriebeverdichtern auszubilden, wobei der eine Getriebeverdichter für die Verdichtung der Hauptluft und der andere Getriebeverdichter für die Verdichtung von Zusatzluft ausgebildet ist, wobei beide Getriebeverdichter mit einer Dampfturbine angetrieben werden. Der eine Getriebeverdichter umfasst in der Regel drei Verdichtungsstufen und zwei Zwischenkühler. Der andere Getriebeverdichter umfasst in der Regel vier bis sechs Verdichterstufen und drei bis fünf Zwischenkühler. Die Getriebeverdichter haben viele mechanische Komponenten (Hohlrad, Ritzelwelle, große Gehäuse usw.), die zu hohen Kosten führen. Außerdem wird meistens ein Zwischengetriebe zwischen der Dampfturbine und des Getriebeverdichters eingesetzt.It is known to design air separation plants with two geared compressors, one geared compressor for compressing the main air and the other geared compressor for compressing additional air, with both geared compressors being driven by a steam turbine. A geared compressor usually includes three compression stages and two intermediate coolers. The other geared compressor typically includes four to six airends and three to five intercoolers. The geared compressors have many mechanical components (ring gear, pinion shaft, large housings, etc.) which result in high costs. In addition, an intermediate gear is usually used between the steam turbine and the geared compressor.

Insbesondere für Anlagen zur Zerlegung von Luft in die einzelnen Bestandteile werden große Verdichtungsleistungen benötigt. In der Regel erfolgt ein derartiger Verdichtungsprozess in zwei miteinander verknüpften Verdichtungsanlagen einem sogenannten Main-Air-Compressor (MAC = Hauptluftverdichter) und einem Booster-Air-Compressor (BAC = > zusätzliche Verdichtung). Herkömmliche MAC werden in der Regel als mindestens dreistufige Getriebeverdichter ausgeführt.
Anordnungen mit einem Getriebeverdichter bzw. Getriebeverdichter sind bereits aus den DE 102010020145 A1 , DE 102009015862 A1 , DE 102014225136 A1 , DE 102015200439 A1 , DE 102015203287 A1 bekannt.Large compression capacities are required in particular for systems for separating air into its individual components. As a rule, such a compression process takes place in two interconnected compression systems, a so-called main air compressor (MAC = main air compressor) and a booster air compressor (BAC = > additional compression). Conventional MACs are usually designed as at least three-stage geared compressors.
Arrangements with a geared compressor or geared compressor are already from the DE 102010020145 A1 , DE 102009015862 A1 , DE 102014225136 A1 , DE 102015200439 A1 , DE 102015203287 A1 known.

Derartige Verdichtungsanlagen sind dementsprechend teuer, weil in der Regel ein Getriebe und mindestens zwei Verdichterwellen benötigt werden, an dessen Wellenenden die entsprechenden Verdichter angebracht werden können. Der hohe Installationsaufwand, die Wartungskosten und die Höhe der Investition schlechthin sind schon aus wirtschaftlichen Gesichtspunkten unerwünscht.Such compression systems are correspondingly expensive because usually a gear and at least two compressor shafts are required, on the shaft ends of which the corresponding compressors can be attached. The high installation effort, the maintenance costs and the amount of the investment are undesirable from an economic point of view.

Die Erfindung hat es sich ausgehend von den bekannten Problemen und Nachteilen des Standes der Technik im Bereich der Luftverdichtungsanlage für eine Luftzerlegung zur Aufgabe gemacht, Investitionskosten zu senken, ohne den Wirkungsgrad derartiger Anlagen nennenswert zu verschlechtern.Based on the known problems and disadvantages of the prior art in the field of air compression systems for air separation, the invention has set itself the task of reducing investment costs without significantly impairing the efficiency of such systems.

a schematic representation of the air compression system according to the invention for air separation.

Die Figur zeigt eine erfindungsgemäße Ausführung einer Luftverdichtungsanlage für eine Luftzerlegung.The figure shows an embodiment of an air compression system for air separation according to the invention.

Die in der Figur 1 dargestellte Luftverdichtungsanlage 1 für eine Luftzerlegung sieht mindestens einen Hauptluftverdichter 2, der auch als Main-Air-Compressor (MAC = Hauptluftverdichter) bezeichnet wird und mindestens einen Booster-Luftverdichter 3, der auch als Booster-Air-Compressor (BAC = > zusätzliche Verdichtung) bezeichnet wird, vor.The air compression system 1 for air separation shown in Figure 1 has at least one main air compressor 2, which is also referred to as the main air compressor (MAC = main air compressor) and at least one booster air compressor 3, which is also referred to as the booster air compressor (BAC => additional compression) before.

Die Luftverdichtungsanlage 1 umfasst des Weiteren eine erste Antriebseinheit 4 zum Antrieb zumindest eines Verdichtermoduls 5, 6 des Hauptluftverdichters 2.The air compression system 1 also includes a first drive unit 4 for driving at least one compressor module 5, 6 of the main air compressor 2.

Der Hauptluftverdichter 2 umfasst einen ersten Verdichterstrang, der mit der ersten Antriebseinheit 4 drehmomentübertragend gekoppelt ist, wobei der Booster-Luftverdichter 3 einen separaten Verdichterstrang umfasst, der mit der zweiten Antriebseinheit 7 drehmomentübertragend gekoppelt ist. Die beiden Verdichterstränge des Hauptluftverdichters 2 und des Booster-Luftverdichter 3 sind zwar strömungstechnisch miteinander verbunden, allerdings besteht keine antriebseitige Verbindung zwischen den beiden Verdichtersträngen. Dadurch werden Kosten eingespart, da keine Getriebe, Kupplungen usw. benötigt werden.The main air compressor 2 includes a first compressor line, which is coupled to the first drive unit 4 in a torque-transmitting manner, with the booster air compressor 3 including a separate compressor line, which is coupled to the second drive unit 7 in a torque-transmitting manner. Although the two compressor trains of the main air compressor 2 and the booster air compressor 3 are fluidically connected to one another, there is no drive-side connection between the two compressor trains. This saves costs because no gears, clutches, etc. are required.

Der separate Verdichterstrang des Booster-Luftverdichters 3 ist mit einem Getriebeverdichter 12 ausgebildet. Der Getriebeverdichter 12 weist hierbei ein Großradzahnrad auf, das über eine Welle 13 mit der zweiten Antriebseinheit 7 drehmomentübertragend gekoppelt ist. Des Weiteren weist der Getriebeverdichter 12 mehrere Planeten-Zahnräder auf, die drehmomentübertragend mit dem Großradzahnrad gekoppelt sind. Eine Drehung des Großradzahnrades führt zu einer Drehung der Planeten-Zahnräder. Jedes Planeten-Zahnrad ist zumindest mit einem Verdichtermodul 8, 9, 10, 11 gekoppelt, so dass die Drehung des Großradzahnrades zur Verrichtung der Dichtungsarbeit in den Verdichtermodulen 8, 9, 10, 11 führt.The separate compressor train of the booster air compressor 3 is designed with a geared compressor 12 . The geared compressor 12 has a large wheel gear which is coupled in a torque-transmitting manner to the second drive unit 7 via a shaft 13 . The geared compressor 12 also includes a plurality of planetary gears torque-transmittingly coupled to the pinion gear. Rotation of the large wheel gear results in rotation of the planetary gears. Each planetary gear is coupled to at least one compressor module 8, 9, 10, 11 so that the rotation of the large wheel gear leads to the performance of the sealing work in the compressor modules 8, 9, 10, 11.

Der Hauptluftverdichter 2 weist zwei Verdichtermodule 5, 6 auf, die mit der ersten Antriebseinheit 4 einen Verdichterstrang bilden. Die erste Antriebseinheit 4 und die zwei Verdichtermodule 5, 6 weisen eine gemeinsame erste Welle 13 auf, wobei die zwei Verdichtermodule 5, 6 über die gemeinsame erste Welle 13 drehmomentübertragend mit der ersten Antriebseinheit 4 gekoppelt sind.The main air compressor 2 has two compressor modules 5, 6, which form a compressor train with the first drive unit 4. The first drive unit 4 and the two compressor modules 5, 6 have a common first shaft 13, the two compressor modules 5, 6 being coupled to the first drive unit 4 in a torque-transmitting manner via the common first shaft 13.

Im Folgenden wird die Funktionsweise der Luftverdichtungsanlage 1 erläutert.The functioning of the air compression system 1 is explained below.

Ein Strömungsmedium strömt über eine erste Leitung 14 in das erste Verdichtungsmodul 5. Das Strömungsmedium kann Luft sein. In dem ersten Verdichtungsmodul 5 wird der Druck und die Temperatur des Strömungsmediums erhöht. Über eine zweite Leitung 15 strömt das Strömungsmedium zu einem ersten Zwischenkühler 16. Im ersten Zwischenkühler 16 wird das Strömungsmedium abgekühlt.A flow medium flows into the first compression module 5 via a first line 14. The flow medium can be air. In the first compression module 5, the pressure and the temperature of the flow medium are increased. The flow medium flows via a second line 15 to a first intermediate cooler 16. In the first intermediate cooler 16, the flow medium is cooled.

Anschließend strömt das Strömungsmedium zu dem zweiten Verdichtermodul 6. Dort wird das Strömungsmedium weiter verdichtet, wobei sich der Druck und die Temperatur erhöht. Das Strömungsmedium strömt anschließend über eine dritte Leitung 17 zu einem zweiten Zwischenkühler 18. In dem zweiten Zwischenkühler wird die Temperatur des Strömungsmediums verringert.The flow medium then flows to the second compressor module 6. There the flow medium is further compressed, with the pressure and the temperature increasing. The flow medium then flows via a third line 17 to a second intermediate cooler 18. The temperature of the flow medium is reduced in the second intermediate cooler.

Die Verdichtungsarbeit in dem Hauptluftverdichter 2 wäre somit abgeschlossen. Die weitere Verdichtungsarbeit wird in dem Booster-Luftverdichter 3 durchgeführt.The compression work in the main air compressor 2 would thus be completed. The further compression work is carried out in the booster air compressor 3 .

Dazu strömt das Strömungsmedium über eine vierte Leitung 19 in ein drittes Verdichtermodul 8. Im dritten Verdichtermodul 8 wird der Druck und die Temperatur des Strömungsmediums erhöht. Anschließend strömt das Strömungsmedium über eine fünfte Leitung 20 zu einem dritten Zwischenkühler 21, wo die Temperatur des Strömungsmediums wieder verringert wird.For this purpose, the flow medium flows via a fourth line 19 into a third compressor module 8. In the third compressor module 8, the pressure and the temperature of the flow medium are increased. The flow medium then flows via a fifth line 20 to a third intermediate cooler 21, where the temperature of the flow medium is reduced again.

Nach dem dritten Zwischenkühler 21 strömt das Strömungsmedium in ein viertes Verdichtermodul 9, wo der Druck des Strömungsmediums weiter erhöht wird, wobei dabei auch die Temperatur ansteigt.After the third intercooler 21, the flow medium flows into a fourth compressor module 9, where the pressure of the flow medium is further increased, with the temperature also rising.

Anschließend strömt das Strömungsmedium zu einem vierten Zwischenkühler 22, wo die Temperatur des Strömungsmediums verringert wird. Nach dem vierten Zwischenkühler 22 strömt das Strömungsmedium über eine sechste Leitung 23 zu einem fünften Verdichtermodul 10, wobei der Druck des Strömungsmediums erhöht wird, wobei sich die Temperatur erhöht.The flow medium then flows to a fourth intercooler 22 where the temperature of the flow medium is reduced. After the fourth intercooler 22, the flow medium flows via a sixth line 23 to a fifth Compressor module 10, wherein the pressure of the flow medium is increased, the temperature increases.

Anschließend strömt das Strömungsmedium über eine siebte Leitung 24 zu einem fünften Zwischenkühler 25, wo die Temperatur des Strömungsmediums verringert wird.The flow medium then flows via a seventh line 24 to a fifth intercooler 25, where the temperature of the flow medium is reduced.

Nach dem fünften Zwischenkühler 25 strömt das Strömungsmedium zu einem sechsten Verdichtermodul 11, wo der Druck und die Temperatur des Strömungsmediums vergrößert wird.After the fifth intercooler 25, the flow medium flows to a sixth compressor module 11, where the pressure and temperature of the flow medium is increased.
