Description
In dem Patent 899 795 ist eine Vorrichtung zum Wärmeaustausch beschrieben, bei der eine aus Rohrbündeln und mehreren Einzelschüssen bestehende Kolonne aus gas- und flüssigkeitsdichtem Graphit Verwendung findet, in der der flüssige Anteil des zu kühlenden bzw. zu erwärmenden Systems durch :einen am oberen Ende jedes Einzelschusses angebrachten Boden und durch schlitzförmige öf!-Tiungen, die an jedem oben verschlossenen Kühlerrohr oberhalb dieses Bodens seitlich angebracht sind, über den Querschnitt jedes einzelnen Schusses gleichmäßig verteilt wird.In the patent 899 795 a device for heat exchange is described, in which a column consisting of tube bundles and several individual sections Gas- and liquid-tight graphite is used in which the liquid part of the system to be cooled or heated by: one at the top of each individual shot attached bottom and through slot-shaped openings, which are closed at the top on each The cooler pipe above this bottom are attached laterally over the cross-section every single shot is evenly distributed.
Bei diesem Verfahren wird das zu absorbierende Gas mit dem die Rohrwände bedeckenden Flüssigkeitsfilm dadurch inniger in Berührung gebracht, daß man da!s Gas innerhalb des einzelnen Rohres durch eine Raschgringfüllung in Wirbelbewegung bringt: Es wurde nun gefunden, daß man die gleiche Wirkung :einer Umlenkung und Wirbelung des Gases, die das Gas zur Wand des Rohres hinleiten, dadurch erzielen kann, da.ß man in den Kühlerröhren Einbauten anbringt, deren Gestaltung das in das Robe - eintretende Gas von dem Weg eines glatten Diurchströmens durch das Rohr ablenkt und durch Wirbelbewegungen innerhalb des Rohres immer wieder in Kontakt mit dem Flüssigkeitsfilm auf der Röhrinnenwand bringt, ohne, daß eine Störung in der Ausbildung des Flüssigkeitsfilms eintritt. Derartige Einbauten können beispielsweise die Form von Stäben haben, die der Längsrichtung der Rohre parallel laufen und die mit periodisch sich wiederholenden, als Umlenkelemente dienenden Ausstülpungen versehen sind.In this process, the gas to be absorbed is combined with the pipe walls the liquid film covering it brought into closer contact by the fact that one is there Gas within the individual tube through a Raschring filling in vortex motion brings: It has now been found that one has the same effect: a deflection and Swirling of the gas, which lead the gas to the wall of the pipe, thereby achieve it is possible that built-in components are installed in the radiator tubes, the design of which corresponds to the Robe - diverting incoming gas from the path of a smooth flow through the pipe and through vortex movements within the pipe again and again in contact with the Brings a liquid film on the inner wall of the tube without causing a disturbance in the formation of the liquid film occurs. Such internals can, for example, take the form of rods which run parallel to the longitudinal direction of the tubes and which are periodic repetitive protuberances serving as deflecting elements are provided.
In der Zeichnung ist :ein derartiges mit Wirbeleinbauten versehenes Kühlrohr dargestellt. Innerhalb des Rahmes i befindet sich der Stab 2, der mit kugelähnlichen Ausstülpungen 3 versehen ist. In diesem Beispiel sind die Ausstülpungen als sich in gleichen Abständen und mit gleicher Form wiederholend dargestellt. Es ist selbstverständlich auch möglich, die Ausstülpungen mit wechselnden Abständen sich wiederholen. zu lassen und ihnen auch verschiedene Formen zu geben.In the drawing is: such a one provided with built-in vortices Cooling tube shown. Inside the frame i is the rod 2, which is similar to the ball Protuberances 3 is provided. In this example the protuberances are as themselves Repeatedly shown at equal intervals and with the same shape. It goes without saying it is also possible for the protuberances to be repeated at alternating intervals. allow and also to give them various forms.
Die Anbringung derartiger Rohreinbauten erfolgt insbesondere in denjenigen Teilen der Apparatur, in denen die Konzentration des Gases bereits niedrig geworden ist. Durch die verstärkte Berührung zwischen, dem zu absorbierenden Gas und dem Flüssigkeitsfilm, wie sie durch die Wirbeleinbauten erzielt wird, erhöht man die Absorptionsmöglichkeiten für das zu behandelnde Gas.The attachment of such pipe installations takes place in particular in those Parts of the apparatus in which the concentration of the gas has already become low is. Due to the increased contact between, the gas to be absorbed and the The liquid film, as it is achieved by the vortex internals, is increased Absorption possibilities for the gas to be treated.
