Abstract

A packing for a mass exchange column consists of a number of strips having their lateral surfaces parallel to the column axis; each strip comprises ribs oriented obliquely (R1) to the column axis, while the ribs of the adjacent strips are oriented obliquely (R2) in a different direction so that the ribs of adjacent strips cross one another. Within each strip (B;B1;B2 etc.) the ribs of a certain length within the strip are offset laterally by one half of the rib spacing from the next length of the same strip. Preferably, the apertures thus formed between successive sets of ribs in the same strip are of such a size that the successive lengths of strip (B5",B5') are connected together at the points between the apertures. This arrangement improves the mixing of downward flowing liquid and ascending gas.

Description

Packung für Stoffaustauschkolonnen Packing for mass transfer columns

Die Erfindung betrifft Packungen für Stoffaustauschkolonnen. Es sind Packungen solcher Art bekannt, die aus mehreren, parallel zur Achse der Austauschkolonne angeordneten, schräg zur Kolonnenachse geriffelten Bändern bestehen, die so angeordnet sind, daR die Riffelungen benachbarter Bänder einander berühren und einander kreuzen (deutsche Patentschrift 1 253 673).The invention relates to packings for mass transfer columns. There are Packings of this type are known, consisting of several, parallel to the axis of the exchange column arranged, obliquely to the column axis corrugated bands exist, which are so arranged that the corrugations of adjacent bands touch and cross each other (German patent specification 1 253 673).

Zweck einer solchen Ausbildung der Packung ist, den Austausch zwischen abströmender Flüssigkeit und aufsteigendem Gas über den gesamten Kolonnenquerschnitt zu vergleichmäßigen.The purpose of such a pack training is to facilitate the exchange between outflowing liquid and rising gas over the entire column cross-section to equalize.

Aufgabe der Erfindung ist es, derartige Packungen so auszubilden, daß eine noch bessere Vermischung von aufsteigendem Dampf und ablaufender Flüssigkeit und damit ein größerer Wirkungsgrad erreicht wird.The object of the invention is to design such packs in such a way that that an even better mixing of rising vapor and draining liquid and thus a greater degree of efficiency is achieved.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Teilung der Rippen auf zwei einander angrenzenden Teilen der Länge des Bandes um die halbe Rippenteilung versetzt ist. Die Versetzung kann über die Länge eines Bandes einmal oder auch mehrmals erfolgen.This object is achieved according to the invention in that the division of the ribs on two adjacent parts of the length of the band by half Rib division is offset. The transfer can be done via the Length of a Band once or several times.

Vorzugsweise besitzen die Bänder an den Stellen, an denen die Versetzung der Rippen stattfindet, Löcher solcher Größe, daß die beiderseits einer solchen Versetzung liegenden Teile des Bandes an zwischen den Löchern liegenden Stellen miteinander verbunden sind.Preferably, the bands have at the points where the dislocation of the ribs takes place, holes of such size that those on either side of such Offset parts of the tape at locations between the holes are connected to each other.

Die Zeichnung zeigt Ausführungsbeispiele der Erfindung.The drawing shows exemplary embodiments of the invention.

Fig. 1 zeigt perspektivisch und teilweise nur schematisch einen Teil einer Packung gemäß der Erfindung, Fig. 2 zeigt perspektivisch einen Teil eines gemäß der Erfindung ausgebildeten Bandes der in Fig. 1 dargestellten Packung, Fig. 3 zeigt perspektivisch einen Teil einer anderen Ausführungsform eines Bandes einer Packung gemäß der Erfindung, Fig. 4 und 5 zeigen in Draufsicht Teile von Bändern gemäß der Erfindung.Fig. 1 shows a part in perspective and partially only schematically a pack according to the invention, Fig. 2 shows in perspective part of a formed according to the invention tape of the pack shown in Fig. 1, Fig. Figure 3 shows in perspective part of another embodiment of a belt of a Pack according to the invention, Figs. 4 and 5 show parts of tapes in plan view according to the invention.

Der in Fig. 1 dargestellte Teil der erfindungsgemäßen Packung besteht aus einer Anzahl einander paralleler, in vertikalen Ebenen liegenden Bändern B bis B5, die durch Faltung mit Rippen versehen sind, die sich bei den Bändern B, B2, B4 in einer Richtung R erstrecken, die in einem Winkel zur Vertikalen steht und bei den Bändern B1, B2, B5 in einer Richtung R2 liegen, die die Richtung R1 kreuzt. Benachbarte Bänder liegen mit ihren Rippen aneinander an.The part of the pack according to the invention shown in FIG. 1 consists from a number of parallel bands B bis lying in vertical planes B5, which are provided with ribs by folding, which are located at the bands B, B2, B4 extend in a direction R which is at an angle to the vertical and at the bands B1, B2, B5 lie in a direction R2 which crosses the direction R1. Adjacent ligaments lie against one another with their ribs.

Bei jedem der Bänder B bis B5 sind die Rippen des Bandes um die halbe Rippenteilung t/2 gegeneinander versetzt, so daß auf dem einen Teil B' der Länge 1 des Bandes (s.For each of the bands B to B5, the ribs of the band are around halfway Rib division t / 2 offset from one another, so that on one part B 'of the length 1 of the volume (see p.

Fig. 2) die eine Rippenteilung t aufweisenden Rippen an dieser Stelle um die halbe Rippenteilung t/2 versetzt ist.2) the ribs having a rib division t at this point is offset by half the rib pitch t / 2.

Während die Fig. 1 und 2 eine Rippung mit scharfkantigen Rippen zeigt, zeigt die Fig. 3 eine im übrigen der Fig.While FIGS. 1 and 2 show ribbing with sharp-edged ribs, FIG. 3 shows an otherwise of FIG.

2 entsprechende Anordnung mit Rippen, die Wellenform haben.2 Corresponding arrangement with ribs that have a wave shape.

Bei dem in Fig. 4 in Draufsicht dargestellten Band einer solchen Packung liegt die Ebene, in der die Versetzung der Teilung der Rippen erfolgt, nicht in der Mitte der Länge 1 des Bandes, sondern ihm gegenüber derart versetzt, daß die Länge der beiden Teile B' und B" des Bandes verschieden groß ist. In dieser Ebene E ist das Band mit Löchern L versehen, die jeweils an einer Stelle vorgesehen sind, an der der Gipfel g der Rippen des einen Teils B' des Bandes in das Tal v der Rippen des anderen Teils B" des Bandes übergeht. Dabei sind die Teile B' und B" des Bandes an den zwischen zwei Löchern L liegenden Stellen miteinander verbunden.In the case of the band of such a pack shown in plan view in FIG the plane in which the displacement of the division of the ribs takes place does not lie in the middle of the length 1 of the tape, but offset from it in such a way that the Length of the two parts B 'and B "of the tape is different. In this plane E, the tape is provided with holes L, each provided at one point, at which the summit g of the ribs of one part B 'of the band in the valley v of the ribs of the other part B "of the tape. Here are parts B 'and B" of the tape connected to each other at the points lying between two holes L.

Das in Fig. 5 dargestellte Band unterscheidet sich von dem in Fig. 4 dargestellten Band dadurch, daß die Ebene E in der Mitte seiner Länge liegt und dadurch,daß das Band an jeder Stelle, an der der Gipfel g einer Rippe in ein Tal v einer Rippe übergeht, mit einem Loch versehen ist.The tape shown in Fig. 5 differs from that in Fig. 4 shown tape in that the plane E is in the middle of its length and in that the band at every point at which the summit g of a rib in a valley v passes over a rib, is provided with a hole.

Die Versetzung der Teilung innerhalb der Höhen eines Bandes bewirkt eine Turbulenz in der Dampfphase und eine Richtungsänderung der ablaufenden Flüssigkeit. Daraus resultiert eine Intensivierung des Austausches. Die Lochung der Bänder an den Stellen der Versetzung der Rippen verhindert, daß Flüssigkeit an der Kante eines Bandes als Bach abläuft.The displacement of the division within the heights of a band causes a turbulence in the vapor phase and a change in direction of the flowing liquid. This results in an intensification of the exchange. The perforation of the straps the points of offset of the ribs prevents liquid from adhering to the edge of a Band as Bach runs out.
