Description

Kolonnenboden Die Trennung von Flüssigkeitsgemischen durch Destillation wird in-Kolonnenapparaten vorgenommen. Wesentlich für-die Leistung und Wirtschaftlichkeit dieser Apparate ist die geeignete Konstruktion der in die Kolonnen eingebauten Böden, von deren Ausführung der Wirkungsgrad der Rektifikation abhängt. Dieser wird um so besser sein, je inniger die Berührung-zwischen.aufsteigendem Dampf und Rückfluß ist.Column bottom The separation of liquid mixtures by distillation is made in-column apparatus. Essential for performance and economy this apparatus is the appropriate construction of the trays built into the columns, on the execution of which the efficiency of the rectification depends. This is going to the better, the closer the contact between the rising steam and the reflux is.

Von den bisherigen Konstruktionen haben sich die sog. Glockenböden besonders bewährt, bei denen der aufsteigende Dampf aus Glocken, deren Rand mit Zungen und Schlitzen versehen ist, in die auf dem Boden siedende Flüssigkeit austritt. Eine bekannte Glockenkonstruktion erreicht durch entspre= Chende Ausbildung der Schlitze, daß der aufsteigende Destillationsdampf am Umfang der Glocke aus der radialen Richtung abgelenkt wird (vgl. Abb. i und 2), so daß ein sich .um die Glocke drehender Flüssigkeitsstrom entsteht. Die besondere Ausbildung dieser Glokken besteht z. B. darin, daß. alle' Zungen gleichsinnig aus den Tangentialebenen des Glockenrandes herausgedreht sind.The so-called bell bottoms have differed from the previous designs especially proven where the rising steam from bells, whose edge with Tongues and slits are provided into which liquid boiling on the bottom escapes. A well-known bell construction is achieved by appropriate training of the Slits that the rising distillation steam on the circumference of the bell from the radial Direction is deflected (see. Fig. I and 2), so that a. To the bell rotating Liquid flow arises. The special training of these bells is z. B. in that. all 'tongues in the same direction from the tangential planes of the bell edge are unscrewed.

Um eine möglichst innige Durchinischung von Dampf und Rückfluß über die ganze Bodenfläche zu gewährleisten, hat man vorgeschlagen (vgl. französisches Zusatzpatent 8 2i2), durch den Einbau von Leitelementen den Rückfluß zwangsläufig über einen langen Weg an möglichst vielen Glocken vorbeizuführen. Der Einbau solcher Leitelemente ist natürlich umständlich und kostspielig. Die Erfindung erreicht dieselbe Wirkung allein durch eine zweckmäßige Wahl des Drehsinnes der Glocken und durch ihre zweckmäßige Anordnung auf dem Boden. Der Inhalt der Erfindung ist der, durch geeignete Wahl des Drehsinnes der einzelnen Glocken und eine zweckentsprechende Aufstellung derselben auf dem Glockenboden dafür zu sorgen, daß der Rücklauf zwischen den Glocken hindurch auf einem möglichst langen Wege_ vom Zulauf zum Überlauf geführt wird. Dies geschieht praktisch dadurch, daß die Glocken zu mehreren in nebeneinander herlaufenden Reihen oder Kurven angeordnet sind, deren Drehsinn abwechselnd rechts- und linksläufig ist (s. Abb. 3 und q.). Zwei nebeneinanderliegende Glockenreihen schließen also eine Bahn ein,- von der aus betrachtet, die auf einer Seite befindliche Glockenreihe den entgegengesetzten Drehsinn wie die Glockenreihe der anderen Seite hat. Es wird dadurch erreicht, daß innerhalb der Bahnen der Flüssigkeit ein kräftiger Bewegungsantrieb in einer einheitlichen, im voraus festzusetzenden Richtung erteilt wird, so daß der Weg, den die Flüssigkeit über den Glockenboden nimmt, zielbewußt in dem Sinne geregelt werden kann, daß er möglichst lang ist.In order to mix the steam and reflux as thoroughly as possible It has been proposed to guarantee the entire floor area (cf. Additional patent 8 2i2), the backflow inevitably due to the installation of guide elements to pass as many bells as possible over a long way. The installation of such Guiding elements are of course cumbersome and expensive. The invention accomplishes the same Effect solely through a suitable choice of the direction of rotation of the bells and through their expedient arrangement on the floor. The content of the invention is that by suitable choice of the direction of rotation of the individual bells and an appropriate one Set up the same on the bell bottom to ensure that the return flow between the bells through the longest possible path from the inlet to the overflow will. This is practically done by placing the bells next to each other running rows or curves are arranged, the direction of rotation of which alternates clockwise and is left-handed (see Fig. 3 and q.). Two rows of bells next to each other thus include a path - viewed from that, the one on one side Row of bells rotates in the opposite direction to the row of bells on the other side Has. It is achieved that within the paths of the liquid a powerful Movement drive issued in a uniform direction to be determined in advance so that the path that the liquid takes over the bell bottom is purposeful can be regulated in the sense that it is as long as possible.

PATENTANSPRUCH: Die Anordnung mehrerer Glocken für Kolonnenböden mit Zungen und Schlitzen für den Dampfaustritt, von der Art, daß alle Zungen gleichsinnig aus den Tangentialebenen des Glockenrandes herausgedreht sind, so daß sie den Dampf aus der radialen Richtung am ganzen Umfang der Glocke im gleichen Drehsinn ablenken, auf einem Kolonnenboden, dadurch gekennzeichnet, daß die Glocken in Reihen angeordnet sind, deren Drehsinn abwechselnd links- und rechtsläufig ist.PATENT CLAIM: The arrangement of several bells for column trays with Tongues and slots for the steam outlet, of the kind that all tongues point in the same direction are rotated out of the tangent planes of the bell edge so that they the steam deflect from the radial direction over the entire circumference of the bell in the same direction of rotation, on a column tray, characterized in that the bells are arranged in rows whose direction of rotation is alternately left and right.
