Description

Verfahren zum Absaugen des Destillates aus den Hilfskondensatoren von Kühlwasserverdunstungsanlagen. Es ist bekannt, erwärmtes Kühlwasser eines Hauptkondensators einem Verdunster zwecks Gewinnung von Speisewasserdestillat zuzuführen und die im Verdunster erzeugten Brüden in einem Hilfskondensator niederzuschlagen, dessen Luftleere etwas höher sein muß als die des Hauptkondensators, Zur Ausübung dieses Verfahrens bei den bisher üblichen Anlagen wird das Destillat entweder unmittelbar oder nach vorheriger Wiederanwärmung unter, - Benutzung vorhandener Wärmequellen dein-' SpeisetWasserbehälter zugeführt. ::.Procedure for sucking the distillate out of the auxiliary condensers of cooling water evaporation systems. It is known to use heated cooling water of a main condenser an evaporator for the purpose of obtaining feedwater distillate and the im Evaporator generated vapors precipitate in an auxiliary condenser, its evacuation Must be slightly higher than that of the main capacitor, in order to perform this procedure in the previous systems, the distillate is either immediately or after prior reheating under, - use of existing heat sources your- 'feed water tank is supplied. ::.

Die Erfindung verbessert die Anlage dadurch, daß das Destillat aus dem Hilfskondensator in die Luftsaugeleitung des Hauptkondensators eingespritzt wird. Durch dieses Verfahren wird der Unterschied zwischen Destillattemperatur und Raumtemperatur des Hauptkondensators ausgenutzt, insofern nämlich die Einspritzung des Destillates in die Luftsaugeleitung des Hauptköndensators eine Temperaturherabsetzung des zur Luftpumpe strömenden Dampfluftgemisches sowie einen größeren Luftteildruck bewirkt. Das Vakuum wird also verbessert bzw. der Kraftbedarf der Luftpumpe herabgesetzt.The invention improves the system in that the distillate from the auxiliary condenser is injected into the air suction line of the main condenser will. By doing this, the difference between the distillate temperature and Room temperature of the main condenser is used, namely the injection of the distillate in the air suction line of the main condenser a temperature reduction of the steam-air mixture flowing to the air pump as well as a larger partial air pressure causes. The vacuum is thus improved or the power requirement of the air pump is reduced.

Eine zur Durchführung des neuen Verfahrens geeignete Anlage ist in der Zeichnung in einem Ausführungsbeispiel dargestellt.A suitable system for carrying out the new process is in the drawing shown in an embodiment.

Aus dem Hilfskondensator H, in dem die vom Verdunster b' kommenden Brüden niedergeschlagen werden, wird das Destillat mit Hilfe der Pumpe D in die vom Hauptkondensatör K zur Luftpumpe L führende Leitung S des Hauptkondensators eingespritzt. Es fließt der Kondensatpumpe P der Hauptkondensation zu und wird von dieser in den Kondensatspeisewasserkreislauf gedrückt. Ein weiterer Vorteil des Verfahrens ist der geringe Kraftbedarf der Destillatpumpe, die nur den Druckunterschied zwischen Hilfskondensator und Hauptkondensator zu übermitteln hat, während die Hauptkondensatpumpe infolge der Vermehrung ihrer Fördermenge einen besseren Wirkungsgrad hat als eine kleine Destillatpumpe. Dadurch, daß das Destillat bzw. Kondensat aus der mit höherem Vakuum .arbeitenden Hilfskondensation in die Lwftsaugeleitung der Hauptkondensation eingespritzt wird, erfolgt nicht nur eine Kühlung des Dampfluftgemisches und somit eine Verbesserung des Vakuums, sondern es wird gleichzeitig auch die Wärme dieses Dampfluftgernisches vom Destillat aufgenommen, das Destillat also erwärmt. Diese aufgenommene Wärme führt Destillat in den Kessel, so daß urimittelbar Wärme gewonnen wird, die sonst verlorengeht.From the auxiliary condenser H, in which the coming from the evaporator b ' Vapors are precipitated, the distillate is pumped into the from the main condenser K to the air pump L leading line S of the main condenser injected. It flows to the condensate pump P of the main condensation and is of this pressed into the condensate feed water circuit. Another benefit of the The method is the low power requirement of the distillate pump, which only changes the pressure between the auxiliary condenser and the main condenser, while the main condensate pump as a result of the increase in their delivery rate has a better efficiency than one small distillate pump. The fact that the distillate or condensate from the with higher Vacuum .working auxiliary condensation in the air suction line of the main condensation is injected, there is not only a cooling of the steam-air mixture and thus an improvement in the vacuum, but it gets the heat of this at the same time Vapor air mixture is absorbed by the distillate, i.e. the distillate is heated. These The absorbed heat leads distillate into the boiler, so that heat is obtained directly that would otherwise be lost.

Durch die Verbesserung des Wirkungsgrades der Luftpumpe wird gleichzeitig die Luftleere der Hauptkondensation verbessert und damit der Dampfverbrauch der Turbine ermäßigt.By improving the efficiency of the air pump, at the same time the evacuation of the main condensation improves and thus the steam consumption of the Turbine reduced.
