Description
Verfahren zur Erzeugung von destilliertem Zusatzwasser bei Kraftmaschinenanlagen, insbesondere Dampfturbinenanlagen. Durch das Patent 3o538= ist ein Verfahren geschützt, bei dem destilliertes Wasser in der Weise erzeugt wird, daß die Abwärme des aus der Turbine austretenden Dampfes zur Beheizung des Rohwasserverdampfers benutzt wird. Die Anordnung des Rohwasserverdampfers in der Abdampfleitung der Turbine oder in einer Zweigleitung derselben ermöglicht an sich noch keine praktische Lösung des Erfindungsgedankens. Es müssen vielmehr noch Vorkehrungen getroffen werden, um in dem Rohwasserverdampfer ein höheres Vakuum als in der Abdampfleitung der Turbine zu erzeugen und aufrechtzuerhalten.Process for generating distilled make-up water in power plant systems, especially steam turbine systems. A process is protected by patent 3o538 = in which distilled water is produced in such a way that the waste heat of the Steam escaping from the turbine is used to heat the raw water evaporator will. The arrangement of the raw water evaporator in the exhaust line of the turbine or in a branch line of the same does not in itself enable a practical solution of the inventive idea. Rather, precautions still need to be taken in order to achieve a higher vacuum in the raw water evaporator than in the exhaust steam line of the turbine to create and maintain.
Die vorliegende Erfindung ist eine weitere Ausgestaltung dieses allgemeinen Erfindungsgedankens und besteht darin, daß das in dem Rohwasserverdampfer zu erzielende höhere Vakuum auf die Weise erzielt wird, da.B zwischen dem Rohwasserverdampfer und dem Kondensator der Kraftmaschine eine Pumpe eingeschaltet wird, die den erforderlichen Druckabfall erzeugt und aufrechterhält.The present invention is a further embodiment of this general one The idea of the invention and consists in the fact that that to be achieved in the raw water evaporator higher vacuum is achieved in the way that B between the raw water evaporator and the condenser of the prime mover a pump is turned on, which the required Generates and maintains pressure drop.
In der Abbildung ist ein Ausführungsbeispiel veranschaulicht. a ist eine Kraftmaschine, b der Abdampfstutzen, durch den der Abdampf mittels des Abdampfrohres c dem Oberflächenkondensator d zugeführt wird. In die Abdampfleitung oder, wie in der Abbildung gezeichnet, in einer Abzweigung derselben befindet sich der Verdampfer e, in dem das zu destillierende Zusatzwasser verdampft wird. Der Abdampf dient dabei als Heizdampf und hat eine Temperatur, die gleich der Sättigungstemperatur entsprechend dem in dem Oberflächenkondensator d herrschenden Druck ist. Um die Verdampfung des dem Verdampfer durch das Rohr f zugeführten Rohwassers zu bewirken, ist es erforderlich, in dem Verdampferraum g ein Vakuum zu schaffen, welches um einen bestimmten Betrag höher ist als das Vakuum, unter dem der Heizdampf steht.An exemplary embodiment is illustrated in the figure. a is a prime mover, b the exhaust steam nozzle, through which the exhaust steam is fed to the surface condenser d by means of the exhaust steam pipe c. The evaporator e, in which the make-up water to be distilled is evaporated, is located in the exhaust steam line or, as shown in the illustration, in a branch of the same. The exhaust steam serves as heating steam and has a temperature which is equal to the saturation temperature corresponding to the pressure prevailing in the surface condenser d. In order to cause the evaporation of the raw water supplied to the evaporator through the pipe f, it is necessary to create a vacuum in the evaporator space g which is higher by a certain amount than the vacuum under which the heating steam is present.
Gemäß der Erfindung wird diese Druckdifferenz auf folgende Weise erzeugt: Die durch das Rohr l aus dem Verdampfer abströmenden Wasserdämpfe werden durch eine Pumpe k in den Hauptkondensator d gefördert. Die Pumpe k ist praktisch wohl als Turbokompressor auszubilden. Der Energieverbrauch für die Destillation besteht demnach in dem Arbeitsbedarf des Kompressors k. Dieser hat aber nur ein ganz geringes Druckgefälle von wenigen Hundertsteln Atmosphären zu überwinden und daraus folgt eine hohe Wirtschaftlichkeit der Destillatgewinnung.According to the invention, this pressure difference is generated in the following way: The water vapors flowing out of the evaporator through the pipe l are through a Pump k promoted into the main condenser d. The pump k is practically well known as Train turbo compressor. The energy consumption for the distillation therefore exists in the labor demand of the compressor k. However, this has only a very small pressure gradient can be overcome by a few hundredths of an atmosphere, resulting in a high level of economy the distillate production.
