Description
Verfahren zum Betrieb von Kondensatoren mit periodisch benetzten Wärmeaustauschelementen. Vorliegende Erfindung bezieht sich auf Verbesserungen bei der Kondensation von Wasserdämpfen oder von anderen Dämpfen durch Hindurchleitung der Dämpfe durch Wärmeaustauschelemente, welche von außen mit verdampfbaren Flüssigkeitsschichten bedeckt sind, und welche so betrieben werden, daß die Benetzung der WärmeauAauschelemente periodisch erfolgt, und daß die benetzten Flächen zwischen aufeinanderfolgenden Benetzungen im wesentlichen getrocknet werden.Method for operating capacitors with periodically wetted heat exchange elements. The present invention relates to improvements in the condensation of water vapors or from other vapors by passing the vapors through heat exchange elements, which are covered from the outside with evaporable layers of liquid, and which be operated in such a way that the wetting of the heat exchange elements takes place periodically, and that the wetted areas substantially between successive wets to be dried.
Die Dampfkondensation in einem solchen Kondensator ist in erster Linie die Folge der Verdunstungskälte beim Verdampfen der dünnen Flüssigkeitsschicht. Um daher eine möglichst starke Kondensationswirkung zu erzielen, wird gemäß vorliegender Erfindung der Strom des zu kondensierenden Dampfes durch die Kondensatorröhren geschwächt oder unterbrochen, während die Röhren in die Netzflüssigkeit eintauchen, so daß der Dampf oder die Hauptmenge desselben zu der Zeit durch die Röhren fließt, während welcher eine besonders starke Wärmeableitung stattfindet. Um die Wirkung zu steigern, empfiehlt -es sich, dafür Sorge zu tragen, daß die Schichtdicke der Netzflüssigkeit auf den Kondensatorröhren möglichst dünn ist, was durch gewisse Zusatzstoffe, die den Kontaktwinkel zwischen Wand und Flüssigkeit vermindern, erreichbar ist. Geeignete Zusatzstoffe für Wasser sind kaustiscbe Soda und Natriumkarbonat.Steam condensation in such a condenser is primary the consequence of the evaporation cold when the thin liquid layer evaporates. In order to achieve the strongest possible condensation effect, according to the present invention Invention of the flow of the steam to be condensed through the condenser tubes weakened or interrupted while the tubes are immersed in the network liquid so that the steam, or most of it, is flowing through the tubes at the time while which a particularly strong heat dissipation takes place. To increase the effect, It is advisable to ensure that the layer thickness of the network liquid on the condenser tubes is as thin as possible, which is due to certain additives that reduce the contact angle between the wall and the liquid is achievable. Suitable Additives to water are caustic soda and sodium carbonate.
Bei der Ausführung der Erfindung, welche einen Kondensator mit einem unterbrechungsweise in eine Flüssigkeit eintauchenden Röhrensystem zur Hindurchleitung des Dampfes voraussetzt, empfiehlt es sich, das Wasser, in welches die Röhren eingetaucht werden, am Auslaßende der Röhreü kälter als am Einlaßende zu halten, um das Vakuum zu steigern. Das kann dadurch erreicht werden, daß die freie Zirkulation des Wassers durch in dem Trog, in dem die Röhren eintauchen, vorgesehene Wände verhindert wird. Die Zwischenwände können zugleich die Träger der Röhren abgeben.In the practice of the invention, which includes a capacitor with a intermittently in a liquid immersed pipe system for passage of steam, it is advisable to use the water in which the tubes are immersed be colder at the outlet end of the tube than at the inlet end to keep the vacuum to increase. This can be achieved by allowing the water to circulate freely is prevented by walls provided in the trough in which the tubes are immersed. The partition walls can also provide the support for the tubes.
Es empfiehlt sich, die Röhren des Kondensators nicht völlig horizontal, sondern ein. wenig geneigt anzuordnen, da hierdurch das Ablaufen der Flüssigkeit nach jedesmaligem Eintauchen nach dem tiefer gelegenen Ende der Röhren hin begünstigt wird.It is advisable to keep the condenser tubes not completely horizontal, but a. to be arranged at a slight incline, as this causes the liquid to run off favored after each immersion towards the lower end of the tubes will.
Die periodische Drosselung des Dampfdurchflusses durch die Röhren kann gemäß vorliegender Erfindung bei der Kondensation beliebiger Dämpfe und beim Betrieb des Kondensators mit beÜebigen Flüssigkeiten Anwendung finden.The periodic restriction of the flow of steam through the tubes can according to the present invention in the condensation of any vapors and in Operation of the condenser with other liquids can be used.
