Description
Um im Betrieb von Kraftwerken Zusatzkondensat als Speisewasser mit möglichst geringen Verlusten zu gewinnen, hat man schon die bekannte Anordnung vorgeschlagen, die in der Abb. I erläutert ist. In order to use additional condensate as feed water in the operation of power plants To gain the lowest possible losses, the known arrangement has already been proposed, which is explained in Fig. I.
In dieser bedeutet T die Turbine, G den mit ihr gekuppelten Generator für elektrischen Strom, I Verdampfer und 2 Vorwärmer, während in den zusätzlichen Kondensatoren 3 wie üblich das bei P eintretende Speisewasser vorgewärmt wird. Bei E wird das Speisewasser eingeführt, dessen Dampf in Kondensatoren 3 niedergeschlagen als Zusatzkondensat für die Kesselspeisung dient. In this T stands for the turbine, G stands for the generator coupled to it for electricity, I evaporator and 2 preheaters, while in the additional Capacitors 3, the feed water entering at P is preheated as usual. at E the feed water is introduced, the steam of which is precipitated in condensers 3 serves as additional condensate for the boiler feed.
Es wurde nun gefunden, daß man die so eingeschalteten Verdampfer I, in denen in Turbinen nicht genütztes Wärmegefälle w irtschäftIich áúsgenützt wird, auch so verwenden kann, daß man bei E an Stelle von Speisewasser eine einzudampfende Lösung oder zu verdampfende Flüssigkeit einführt, die Dämpfe in dem Kondensator 3 verflüssigt und die Flüssigkeitswärme in einem weiteren, nicht eingezeichneten Kühlersystem zum Vorwärmen des Kesselspeisewassers verwendet. It has now been found that you can turn on the evaporator I, in which unused heat gradient in turbines is economically used is, can also be used in such a way that at E instead of feed water one is to be evaporated Solution or liquid to be evaporated introduces the vapors into the condenser 3 liquefied and the heat of the liquid in another, not shown Cooling system used to preheat the boiler feed water.
Als verdampfbare Flüssigkeiten können Lösungen oder Suspensionen dienen, die man eindicken will. Man kann aber bei E auch Flüssigkeiten oder Flüssigkeitsgemische einführen, die man destillieren oder fraktioniert destillieren will. Solutions or suspensions can be used as vaporizable liquids that you want to thicken. Liquids or mixtures of liquids can also be used for E. introduce that one wants to distill or fractionally distill.
In gleicher Weise können die so geschalteten Verdampfer auch zu beliebigen anderweitigen Vorwärmezwecken verwendet werden. In the same way, the evaporators switched in this way can also be used as desired used for other preheating purposes.
Beispielsweise kann man die in Abb. 2 skizzierte Verdampferschaltung für eine Absorptionskälteanlage verwenden, indem man bei E z. B. Ammoniakwasser einführt; in dem Verdampfer I als Kocher wird Ammoniak ausgetrieben und im Kondensator 3 wieder verflüssigt. Das flüssige Ammoniak erzeugt in bekannter Art Kälte in einer nicht gezeichneten Vorrichtung. Das zurückkommende Ammoniakgas wird in einer niederen Vorwärmestufe absorbiert und gelangt als Ammoniaklösung wieder in den Kocher I. Man kann auch die Absorberstufe in eine noch tiefere Temperaturstufe der Vorwärmung legen. Es ist dann zweckmäßig, die Wärme des flüssigen Ammoniaks in einer zwischengeschalteten Vorwärmstufe auszunützen. For example, the evaporator circuit shown in Fig. 2 can be used for an absorption refrigeration system by adding e.g. B. ammonia water introduces; In the evaporator I as a digester, ammonia is expelled and in the condenser 3 liquefied again. The liquid ammonia creates cold in a well-known way device not shown. The returning ammonia gas is in a lower The preheating stage is absorbed and returned to the cooker I as ammonia solution. You can also preheat the absorber stage in an even lower temperature stage place. It is then expedient to use the heat of the liquid ammonia in an intermediate Take advantage of the preheating stage.
PATENvANsPRÜcHE: I. Verfahren zur Ausnützung des in Dampfturbinen mit mehrstufiger Anzapfung nicht genützten Wärmegefälles durch Einschalten von an sich bekannten Verdampfern zwischen die einzelnen Anzapfstellen, dadurch gekennzeichnet, daß man die Verdampfer zum Erwärmen, Eindampfen, Eindicken, Destillieren oder fraktiomerten Destillieren von Flüssigkeiten oder Lösungen verwendet. PATENT CLAIMS: I. Process for utilizing the in steam turbines with multi-stage tapping unused heat gradient by switching on known evaporators between the individual taps, characterized in that that you can use the evaporator for heating, evaporating, thickening, distilling or fractiomerten Used for distilling liquids or solutions.
