Description

Dampfspeicheranlage. Es ist bekannt, Abfallenergie dadurch aufzuspeichern, daB man mit ihr Dampf aus einem Speicher niederen Druckes. in einen Speicher höheren Druckes fördert. Zu gewünschter Zeit läBt man diesen Dampf dann Arbeit verrichtend wieder in den Speicher niederen Druckes expandieren.Steam storage system. It is known to store waste energy by that it is used to produce steam from a reservoir of low pressure. in a memory higher Pressure promotes. At the desired time, this steam is then left to do work expand again into the low pressure storage.

Bei dieser Verdichtung 'des Dampfes auf höheren Druck geht aber ein großer Teil der Energie durch die Kühlung des Verdichters verloren. Zweck der Erfindung ist, diese Kühlung so zu gestalten, daß die Verdichtungswärme dem Energiespeicherungsverfahren zugute kommt, wodurch der Wirkungsgrad der Speicherung wesentlich erhöht wird.With this compression 'of the steam to higher pressure, however, goes into much of the energy is lost by cooling the compressor. Purpose of the invention is to make this cooling so that the heat of compression to the energy storage process benefits, whereby the efficiency of the storage is significantly increased.

Zu diesem Zweck wird als Kühlflüssigkeit für den Verdichter die Speicherflüssigkeit des. Niederdruckspeichers verwendet und entweder die Flüssigkeit erwärmt und wieder zu diesem zurückgeführt, oder die Flüssigkeit verdampft und in den Saugstutzen des Verdichters eingeführt.For this purpose, the storage liquid is used as the cooling liquid for the compressor Des. Low-pressure accumulator is used and either the liquid is heated and again returned to this, or the liquid evaporates and in the Compressor suction nozzle introduced.

An Hand der Zeichnung, die schematisch diese beiden Fälle beispielsweise zeigt, sei die Erfindung näher veranschaulicht.On the basis of the drawing, which schematically shows these two cases, for example shows, the invention is illustrated in more detail.

In Abb. i ist a der Speicher niederen und b derjenige höheren Druckes. Der Verdichter c mit Saugleitung d und Druckleitung e fördert Dampf vom Speicher a in den Speicher b, dient also als Wärmepumpe. Ob ein Kolben- oder Kreiselverdichter angewendet wird, ist mit Bezug zur ErfinAung gleichgültig. Mittels einer Pumpe f wird Flüssigkeit aus dem Speicher a im Kreislauf durch den Kühler g des Verdichters und durch Leitung h wieder zurück zurr Speicher a. geführt.In Fig. I, a is the storage tank with lower pressure and b is the one with higher pressure. The compressor c with suction line d and pressure line e conveys steam from the accumulator a in the memory b, so it serves as a heat pump. Whether a piston or centrifugal compressor is applied is indifferent with respect to the invention. By means of a pump f is liquid from the memory a in the circuit through the cooler g of the compressor and through line h back to memory a. guided.

@Uan ist leicht versucht, anzunehmen, daß dadurch die Temperatur der Speicherflüssigkeit derart erhöht würde, daß sie nach einiger Zeit nicht mehr als Kühlflüssigkeit dienen könnte. Dies ist jedoch nicht der Fall, da durch die Verdampfung der Speicherflüssigkeit dieser dauernd wesentlich mehr Wärme entzogen als durch die Verdichtungswärme zugeführt wird. Die Zuführung der Verdichtungswärme hat den Vorteil, daß die Temperaturabnahme der Speicherflüssigkeit und damit des Speicherdruckes langsamer erfolgt als ohne diese.@Uan is tempted to assume that the temperature of the Storage fluid would be increased so that after some time they no longer than Could serve coolant. However, this is not the case because of the evaporation the storage fluid is constantly drawing much more heat from it than by the compression heat is supplied. The supply of compression heat has the Advantage that the temperature decrease of the storage liquid and thus the storage pressure occurs more slowly than without it.

Die Erhaltung der Verdichtungswärme für das Speicherverfahren kann auch nach Abb. a ermöglicht werden, indem ein Teil der Speicherflüssigkeit im Kühler g zur Verdampfung gebracht und als Dampf durch Leitung i in den Saugstutzen d des Verdichters c eingeführt wird, so daß dessen Wärme statt im Niederdruckspeicher a, im Hochdruckspeicher b zur Geltung kommt.Preservation of the heat of compression for the storage process can also be made possible according to Fig. A, by causing part of the storage liquid to evaporate in the cooler g and introducing it as vapor through line i into the suction nozzle d of the compressor c, so that its heat instead of in the low-pressure accumulator a, comes into play in the high-pressure accumulator b.
