Description
Dichtung für Wärmeaustauscher mit rotierendem Regenerator. Diese Erfindung bezieht sich auf eine Dichtung für Wärmeaustauscher mit rotieren dem Regenerator, welche z. B. in Gasturbinen anlagen aller Typen verwendet werden kann.
Die Erfindung ist dadurch gekennzeichnet, dass sie teilweise Kohlenstoff und teilweise metallisches Material aufweist, letzteres zur Leitung der Wärme vom Kohlenstoff an ein Kühlmedium, und dass sie zur direkten Be- rülirung- der bewegten Oberfläche des Wärme- austauschers bestimmt. ist.
In der beiliegenden Zeichnung sind sche matisch einige Ausführungsbeispiele im Schnitt dargestellt Fig. 1 zeigt eine Dichtung, bestehend aus Metall- und Kohlenstoffplatten.
Fig. 2 zeigt eine Variante, bei welcher der Kohlenstoff in Taschen in einem metallischen Schuh eingesetzt ist.
Fig. 3 zeigt eine verbesserte Form der in Fig. 1 gezeigten Anordnung.
Bei der Ausführungsform gemäss der Fig.1, besteht die Dichtung aus einer Anzahl von Kohlenstoffplatten b, kombiniert abwechselnd mit einer Anzahl Metallplatten a, wobei das Ganze durch nicht dargestellte Bolzen zusam inengehalten wird. Die Fig. 1 zeigt eine An ordnung für einen Austauscher der Trommel type, bei welcher die Dichtung erforderlich ist, um quer zur Umfangsrichtung der Trom mel deren Länge entlang dichten zu können. Im gezeichneten Beispiel ist nur die Dichtung auf der Aussenseite der Trommel- gezeichnet.
In Fig. 2 ist eine Variante dargestellt, wo bei der Kohlenstoff d in Taschen im metal lischen Schuh c derart eingesetzt ist, dass die Dichtungsfläche des Schuhs in abwechselnder Reihenfolge Metall- und Kohlenstoffstreifen aufweist.
Bei der in Fig.3 dargestellten Ausfüh rungsform sind die Metallplatten e höher als die Kohlenstoffplatten f, so dass die Teile g der Metallplatten in eine Kühlkammer h ragen, welche durch den Träger der Dichtung gebildet wird.
Die Metallplatten gemäss der Fig.1 oder 3, oder der Schuh gemäss Fig. 2 können aus irgendeinem hitzebeständigen Material be stehen, so z. B. aus Chromstahl, und in allen Fällen dienen die Metallplatten zur Ueber- tragung der Wärme an ein Kühlmedium. Ge mäss Fig. 3 wird die Wärme von den freien Seitenflächen der Metallplatten z. B. durch Luftkühlung abgeleitet.
In allen diesen Anwendungen ist die bevor zugte Form des Kohlenstoffes der Graphit, doch könnte jedes andere kohlenstoffhaltige Schmiermittel, das sich unter den erforder lichen Dichtungsbedingungen und hohen Temperaturen bewährt, ebensogut verwendet werden; beispielsweise können als Schmier mittel verwendet werden: Nickel-, Chrom-, Silber-Kupfer-Mischungen und andere metal lische Pulver, die mit Kohlenstoff kombiniert sind, sowie gewöhnliches Gusseisen, in welchem sich der Kohlenstoff in fein verteilter Form befindet. In allen diesen Fällen hilft der Kohlenstoff, ein Schmiermittel zu bilden, das bei hohen Temperaturen eine wirksame rei bende Dichtungsfläche bildet.
Seal for heat exchanger with rotating regenerator. This invention relates to a seal for heat exchangers with rotating regenerator, which e.g. B. in gas turbine systems of all types can be used.
The invention is characterized in that it comprises partly carbon and partly metallic material, the latter for conducting the heat from the carbon to a cooling medium, and that it is intended for direct irrigation of the moving surface of the heat exchanger. is.
In the accompanying drawings, some exemplary embodiments are shown in section. Fig. 1 shows a seal consisting of metal and carbon plates.
Fig. 2 shows a variant in which the carbon is inserted in pockets in a metallic shoe.
FIG. 3 shows an improved form of the arrangement shown in FIG.
In the embodiment according to FIG. 1, the seal consists of a number of carbon plates b, combined alternately with a number of metal plates a, the whole being held together by bolts, not shown. Fig. 1 shows an arrangement for an exchanger of the drum type, in which the seal is required in order to be able to seal along the length of the drum transversely to the circumferential direction of the drum. In the example shown, only the seal on the outside of the drum is shown.
In Fig. 2 a variant is shown where the carbon d is inserted in pockets in the metallic shoe c in such a way that the sealing surface of the shoe has metal and carbon strips in alternating order.
In the embodiment shown in Figure 3, the metal plates e are higher than the carbon plates f, so that the parts g of the metal plates protrude into a cooling chamber h, which is formed by the carrier of the seal.
The metal plates according to FIG. 1 or 3, or the shoe according to FIG. 2 can be made of any heat-resistant material, such. B. made of chrome steel, and in all cases the metal plates are used to transfer the heat to a cooling medium. Ge according to Fig. 3, the heat from the free side surfaces of the metal plates z. B. derived by air cooling.
In all of these applications, the preferred form of carbon is graphite, but any other carbonaceous lubricant that works under the required sealing conditions and high temperatures could just as easily be used; For example, the following lubricants can be used: nickel, chromium, silver-copper mixtures and other metallic powders that are combined with carbon, as well as ordinary cast iron in which the carbon is in finely divided form. In all of these cases the carbon helps to form a lubricant that forms an effective friction sealing surface at high temperatures.
