Description

Wärmeaustauscheinrichtung, insbesondere für Ölkühler bei Dampfturbinenanlagen, die einen Längsabschnitt des Kondensators bildet Es sind mit dem Kondensator von Dampfturbin.enanlagen verbundene Wärmeaustauscheinrichtungen bekanntgeworden, bei denen :eine Wasserkammer- des Kondensators dazu benutzt wird, um auch andere Mittel des Arbeitskreislaufs als Dampf, z. B. die Kühlluft :eines mit der Dampfturbine verbundenen elektrischen Generators, in den Kühlwasserstrom einzuschalten und rückzukühlen. Hierbei ist der Kühler in eine Wasserkammer eingebaut oder bildet unmittelbar einen Längsabschnitt des Kondensators, so daß er von der gesamten oder einem Teil der Kühlwassermenge des Kondensators durchflossen wird. Die Anordnung hat gegenüber der Aufstellung eines besonderen Kühlers für Luft oder ein anderes Arbeitsmittel den Vorteil, daß besondere -Kühlwasserleitungen erspart werden, wodurch die Gesamtanlage einfacher, übersichtlicher, weniger Raum einnehmend und billiger wird. Dieselbe Anordnung kann natürlich auch für . die Rückkühlung des Schmieröls für die Lager der Turbine und für ein Zahnradgetriebe getroffen werden, sofern es sich z. B. um eine Getriebeturbinenanlage handelt. Ferner ist bereits eine Anordnung bekannt, bei der der Kühler des einen Mittels unmittelbar einen Längsabschnitt des Kondensators bildet und in einem vom Kondensator losnehmbaren besonderen Gehäuse untergebracht ist, wobei die Rohre des Kühlers die gleiche Anordnung und Teilung wie die Rohre des Kondensators haben. Dies hat den Vorteil, daß die Rohrplatten des Kondensators und des Kühlers gemeinschaftlich gebohrt werden können. Die Erfindung besteht nunmehr darin, daß die Rohre des Kühlers, z. B. des Ölkühlers, einen um einen geringen Betrag, z. B. 5 bis höchstens io%, größeren lichten Durchmesser besitzen als die Kondensatorrohre, so daß etwaige schadhafte Kondensatorrohre in bequem@er Weise derart ausgeschaltet werden können, daß sie durch einen durch die Rohre des Ölkühlers hindurchgesteckten Pflock abgeschlossen werden.Heat exchange device, especially for oil coolers in steam turbine systems, which forms a longitudinal section of the capacitor There are with the capacitor of Dampfturbin.enanlagen associated heat exchange devices become known at which: a water chamber- the condenser is used for other means of the working cycle as steam, e.g. B. the cooling air: one with the steam turbine connected electrical generator, to switch on in the cooling water flow and to cool down. Here the cooler is built into a water chamber or directly forms one Longitudinal section of the capacitor so that it is covered by all or part of the Cooling water volume of the condenser is flowing through. The arrangement has opposite the installation of a special cooler for air or other work equipment the advantage that special cooling water lines are saved, which means the entire system becomes simpler, clearer, less space consuming and cheaper. Same Arrangement can of course also for. the recooling of the lubricating oil for the bearings the turbine and be taken for a gear transmission, provided that it is z. B. to a geared turbine system is involved. Furthermore, an arrangement is already known in which the cooler of the one means is directly a longitudinal section of the condenser forms and housed in a special housing detachable from the capacitor The tubes of the cooler have the same arrangement and pitch as the tubes of the capacitor. This has the advantage that the tube plates of the condenser and the cooler can be drilled jointly. The invention now exists in that the tubes of the cooler, e.g. B. the oil cooler, a small amount, z. B. 5 to a maximum of 10%, larger inside diameter than the condenser tubes, so that any damaged condenser tubes are conveniently switched off in this way can be that they are inserted through one of the pipes of the oil cooler Peg to be completed.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in den Abb. i und a dargestellt. Es bezeichnet i den Mantel des Kondensators, der für einmaligen Wasserdurchfluß angenommen ist und in den bei a der Dampf eintritt. 3 bezeichnet die Rohre des Kondensators, die, in den Rohrplatten 4., 5 in üblicher Weise befestigt, in vorteilhafter Weise eingewalzt sein können. Bei 6 tritt das Kühlwasser in die Wasserkammer 7, bei 8 tritt @es aus der Wasserkammer 9 aus. io bezeichnet die Fortsetzung des Kondensatormantels, durch die das ölkühlergehäuse gebildet wird. i i bezeichnet die Rohre des Ölkühlers, deren Anordnung und Teilung die gleiche ist wie die der Kondensatorrohre. Die Rohre i i sind in die vom Kondensator losnehmbar getrennten Rohrplatten 12 und 13 eingewalzt, bei welcher -Bauweise der Ölkühler bequem -vom Kondensator abgebaut werden kann und keine besonderen Unterstützungen erfordert. Die Rohrplatte 12 äs ölkühler s ist hierbei von der Kondensatär, rohrplatte durch den Zwischenring 1q. getrennt, welcher Zwischenring, um möglichst geringe tibergangsniderstände für das I-,'-ühlwasser zu erhalten, nur so hoch ist, daß die vorstehenden Einwalzenden der Rohre 3 und ii genügend Platz haben.In the drawing, an embodiment of the invention is shown in Figs. I and a. I denotes the jacket of the condenser, which is assumed for a single flow of water and into which the steam enters at a. 3 denotes the tubes of the condenser, which, fastened in the usual way in the tube plates 4, 5, can advantageously be rolled. At 6 the cooling water enters the water chamber 7, at 8 @ it emerges from the water chamber 9. io refers to the continuation of the condenser jacket, through which the oil cooler housing is formed. ii denotes the tubes of the oil cooler, the arrangement and spacing of which is the same as that of the condenser tubes. The tubes ii are rolled into the tube plates 12 and 13 , which are detachably separated from the condenser, in which construction the oil cooler can conveniently be dismantled from the condenser and does not require any special support. The tube plate 12 as oil cooler s is here from the condenser, tube plate through the intermediate ring 1q. separately, which intermediate ring, in order to obtain the lowest possible transition resistances for the I -, '- ühlwasser, is only so high that the protruding rolled-in ends of the tubes 3 and ii have enough space.

Um schadhafte Kondensatorrohre auch ohne Abbau des Ölkühlers ausschalten zu können, was in üblicher Weise durch Abstöpseln geschieht, sind die Rohre des _ Ölkühlers, wie aus Abb. 2 hervorgeht, im lichten Durchmesser etwas größer gehalten, es genügt etwa 5 bis höchstens i o %, als die Kondensatorrohre 3, um die. Stöpsel bequem durch die Rohre des Ölkühlers hindurchführen zu können. Der Vorteil dieser Ausführung besteht darin, daß im Falle des Schadhaftwerdens von Kondensatorrohren der Ölkühler mit den daran hängenden Rohrleitungen, ebenso die 1Iäuptkühlwasserrohre nicht abgebaut zu werd.en brauchen, daher die Anlage in kürzester geit wieder betriebsbereit ist.To switch off damaged condenser tubes without removing the oil cooler to be able to do what happens in the usual way by unplugging, the tubes of the _ The clear diameter of the oil cooler, as shown in Fig. 2, is slightly larger, it is sufficient about 5 to at most 10%, as the condenser tubes 3 to the. plug to be able to comfortably pass through the pipes of the oil cooler. The advantage of this Execution is that in the case of the condenser tubes becoming damaged the oil cooler with the pipes attached to it, as well as the main cooling water pipes do not need to be dismantled, so the system is ready for operation again in next to no time is.
