Abstract

The integrated sea water desalination plant for solar-thermal power station, comprises a steam power station, where the condensed steam (2) of a steam power station delivers heat in a sea water inlet and receives heat in a row of flash-steam generating chamber before the steam is brought to the power tool as feed water, and additional heat is brought to heated sea water.

Description

Die Erfindung betrifft eine Meerwasserentsalzungsanlage, die in den Kondensationskreislauf eines Dampfkraftwerks integriert ist. Da die Notwendigkeit der Trinkwasserversorgung durch Meerwasserentsalzung in sonnenreichen Ländern stark vorhanden ist, empfiehlt es sich hierzu solarthermische Kraftwerke einzusetzen, die hier durch Kraft-Wärme-Nutzung die Bereitstellung von elektrischer Energie, Trinkwasser und Klimatisierung leisten können.The The invention relates to a seawater desalination plant, which in the Condensation circuit of a steam power plant is integrated. There the need for drinking water supply through seawater desalination in sunny countries strong, it is recommended for this solar thermal power plants to deploy that here by providing power-heat usage of electricity, drinking water and air conditioning can.

Bei den bekannten Multi-Stage-Flash (MSF) Verfahren, das in Anbindung an Kraftwerke betrieben wird wird Abwärme eines Kraftwerks zur Bereitstellung der benötigten Kopftemperatur genutzt. Das erhitzte Meerwasser wird in eine Reihe von Verdampfungskammern geleitet, in denen eine Teilverdampfung stattfindet wobei Druck und Temperatur von Kammer zu Kammer abgesenkt ist. Der kondensierende Dampf wird als Endprodukt aufgefangen und abgeleitet und überträgt Kondensationswärme an mit Meerwasser durchströmten Rohren, das dem Prozess zugeführt wird.at the well-known multi-stage flash (MSF) method, which in connection At power plants is operated waste heat of a power plant to provide the needed Head temperature used. The heated seawater gets into a row passed by evaporation chambers, in which a partial evaporation takes place while pressure and temperature lowered from chamber to chamber is. The condensing vapor is collected and discharged as an end product and transfers heat of condensation with seawater perfused Pipes that fed to the process becomes.

Bei dem der Erfindung zugrunde liegendem Verfahren wird das Kondensat des Kraftwerks im Gegenstrom eines Meerwassereinlaufs weiter abgekühlt bevor es in Rohren die Verdampfungskammern durchströmt die ansonsten gegenüber dem eingeführten MSF-Verfahren weitgehend identisch sind, die Kondensationswärme des verdampften Meerwassers aufnimmt und zur weiteren Erwärmung dem Kraftwerk zugeführt wird.at the invention of the underlying method is the condensate the power plant in countercurrent to a seawater inlet further cooled before it flows in pipes the evaporation chambers which otherwise opposite to the introduced MSF process are largely identical, the heat of condensation of the evaporated seawater absorbs and further warming the power plant supplied becomes.

Der Vorteil eines solchen Verfahrens liegt darin begründet, dass der Wärmetausch in den Verdampfungskammern nicht an mit Meerwasser durchströmten Rohren, sondern an mit dem Speisewasser des Kraftwerks durchströmten Rohren stattfindet. Dadurch werden Korrosionsprobleme leichter beherrschbar und kostengünstigere Materialien einsetzbar.Of the The advantage of such a method lies in the fact that the heat exchange in the evaporation chambers not on seawater flowed pipes, but on with the feed water of the power plant flowed through pipes takes place. This makes corrosion problems easier to control and cheaper Materials used.

Es ergibt sich folgendes Schema: Der aus der Dampfturbine (1) austretende Dampf (2) wird im Meerwassereinlauf (3) im Gegenstrom kondensiert und abgekühlt und tritt als Kondensat in die Verdampfungskammer (4) mit dem niedrigsten Druck- und Temperaturverhältnis ein. Das verdampfte Meerwasser kondensiert an dem mit Speisewasser des Kraftwerks durchströmten Rohrbündel (5), das Destillat wird aufgefangen und abgeleitet (6). Das in dem Gegenstromwärmetauscher (3) erwärmte Meerwasser (7) wird in die Verdampfungskammer mit dem höchsten Druck- und Temperaturverhältnis geleitet (8), wo es teilweise verdampft und der Dampf kondensiert. Das Meerwasser wird bei der Durchleitung durch alle Verdampfungskammern durch den Entzug der Verdampfungswärme abgekühlt und aufkonzentriert abgeleitet (9). Das Speisewasser wird nach der Durchleitung durch die Verdampfungskammern dem Kraftwerk zugeführt (10).The result is the following scheme: The from the steam turbine ( 1 ) exiting steam ( 2 ) is used in seawater intake ( 3 ) is condensed in countercurrent and cooled and enters the evaporation chamber as condensate ( 4 ) with the lowest pressure and temperature ratio. The evaporated seawater condenses on the throughput with feed water of the power plant tube bundle ( 5 ), the distillate is collected and discharged ( 6 ). In the countercurrent heat exchanger ( 3 ) heated seawater ( 7 ) is passed into the evaporation chamber with the highest pressure and temperature ratio ( 8th ), where it partially evaporates and the vapor condenses. The seawater is cooled in the passage through all evaporation chambers by the withdrawal of the heat of vaporization and derived concentrated ( 9 ). The feed water is supplied to the power plant after passing through the evaporation chambers ( 10 ).
