Description

Vorrichtung zum Wärmeaustausch Zusatz zum Patent 899, 395 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 Öffnungen, die an jedem oben verschlossenen Kühlerrohr oberhalb dieses Bodens seitlich angebracht sind, über den Querschnitt jedes einzelnen Schusses gleichmäßig verteilt wird.Device for heat exchange Addendum to patent 899, 395 In the patent 899 795 describes a device for heat exchange in which one of tube bundles and several individual sections consisting of a gas- and liquid-tight column Graphite is used in which the liquid portion of the to be cooled or heated System through a floor attached to the upper end of each individual section and through slot-shaped openings, which are on each closed top radiator tube above this Mounted on the bottom, evenly across the cross-section of each individual shot is distributed.

Es wurde gefunden, daß es zweckmäßig sein kann, diese Einzelschüsse nicht völlig gleichmäßig auszubilden, sondern daß es unter Umständen von Vorteil ist, die Anzahl und den Querschnitt der in den einzelnen Schüssen angebrachten Rohre so zu ändern, daß in einem Teil der Kolonne eine Vergrößerung der Gesamtinnenwandfläche der Rohre durch Erhöhung der Anzahl der Einzelrohre und entsprechende Verringerung ihrer Querschnitte erzielt wird.It has been found that it can be useful to shoot these single shots not to train completely evenly, but that it may be an advantage is the number and the cross-section of the pipes installed in the individual sections to change so that in part of the column an increase in the total inner wall area of the pipes by increasing the number of individual pipes and reducing them accordingly their cross-sections is achieved.

Beispielsweise hat es sich im Fall der Salzsäureabsorption als vorteilhaft erwiesen, die den oberen Teil der Kolonne bildenden Einzelschüsse, in denen die Salzsäurekonzentration der behandelten Gase bereits erheblich vermindert ist, mit einer größeren Anzahl engerer Rohre auszustatten. Auf diese Weise erhält man dort eine Vergrößerung der Innenfläche der Kühlerrohre. Hierdurch wird am oberen Ende der Kolonne, wo es sich darum handelt, die restliche, unter Umständen mit neutralem Inertgas stark verdünnte Salzsäure mit dem fallenden Flüssigkeitsfilm in Reaktion zu bringen, eine wesentliche Vergrößerung der Reaktionsfläche Gas-Flüssigkeit erzielt.For example, it has proven advantageous in the case of hydrochloric acid absorption proved to be the single shots forming the upper part of the column, in which the Hydrochloric acid concentration of the treated gases is already considerably reduced, with to equip a larger number of narrower pipes. To this way you get there an enlargement of the inner surface of the cooler tubes. This will at the top of the column, where it is, the rest of the column, possibly Hydrochloric acid, strongly diluted with neutral inert gas, with the falling liquid film To bring into reaction, a substantial increase in the gas-liquid reaction surface achieved.
