Description

Die Erfindung betrifft eine Kolonne zum Durchführen thermischer Trennungen und/oder chemischer Reaktionen mit einer senkrechten zylindrischen Kolonnenaußenwand, die reinen Innenraum umgibt, der durch eine mittlere senkrechte Trennwand (Trennblech) in zwei Raumhälften unterteilt ist, in denen Stoffaustauschpakete(-packungen) angeordnet sind, die an den Außenseiten waagerecht bandförmige Randabweiser aufweisen, die die an den Innenseiten der Kolonnenaußenwand entlangfließende Flüssigkeit zum Stoffaustauschpaket führen.The invention relates to a column for performing thermal separations and / or chemical reactions with a vertical cylindrical column outer wall, the pure interior that is surrounded by a central vertical Partition (partition) divided into two halves of the room is arranged in which mass transfer packages (packs) are horizontally band-shaped on the outside Have edge deflectors, which on the inside of the Liquid flowing along the outer wall of the column for Lead mass exchange package.

Es ist bekannt, den zylindrischen Innenraum einer Kolonne durch eine mittlere Trennwand in zwei gleich große Räume zu teilen EP 012 62 88 und EP 012 23 67. Ein exaktes Befestigen der Trennwand an der Innenwand der Kolonne ist arbeitsaufwendig, zumal oft erhebliche Maßungenauigkeiten entstehen können.It is known the cylindrical interior of a column through a central partition into two rooms of the same size to be shared EP 012 62 88 and EP 012 23 67. An exact one Attach the partition to the inner wall of the column labor-intensive, especially since there are often considerable dimensional inaccuracies can arise.

Aufgabe der Erfindung ist es eine Kolonne der eingangs genannten Art so zu verbessern, daß bei einfacher Konstruktion und hoher Dichtigkeit die Trennwand leicht und exakt befestigbar ist. The object of the invention is a column of the beginning to improve the type mentioned so that at simple Construction and high tightness the partition wall easily and can be attached exactly.  

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Kolonnenaußenwand in zwei Halbschalen geteilt ist, deren senkrechte Ränder (Stirnseiten) an den Seitenflächen der Trennwand befestigt sind.This object is achieved in that the Column outer wall is divided into two half-shells, the vertical edges (end faces) on the side surfaces of the Partition are attached.

Hierdurch ist die Trennwand besonders einfach und mit großer Genauigkeit an der Außenwand einer Kolonne befestig­ bar. Bei geringem Arbeitsaufwand wird eine absolute Dicht­ igkeit erreicht. Die Konstruktion eignet sich besonders für Kolonnen mit kleinerem Durchmesser. Besonders vorteilhaft ist es hierbei, wenn die senkrechten Ränder (Stirnseiten) der Halbschalen nahe den senkrechten Seiten/Rändern der Trennwand an dieser befestigt insbesondere angeschweißt sind.As a result, the partition is particularly simple and with attached to the outer wall of a column with great accuracy bar. With little effort, an absolute seal achieved. The construction is particularly suitable for Columns with a smaller diameter. Particularly advantageous it is here if the vertical edges (end faces) the half shells near the vertical sides / edges of the Partition attached to this welded in particular are.

Ein Ausführungsbeispiel der Erfindung ist in den Zeich­ nungen dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the drawing shown and is described in more detail below.

Es zeigen:Show it:

Fig. 2: Ein Ausschnitt A aus Fig. 1 in vergrößertem Maßstab. Fig. 2: A section A of Fig. 1 on an enlarged scale.

Die Kolonnen zum Durchführen thermischer Trennungen und/ oder chemischer Reaktionen weist eine Außenwand 1 in Form eines senkrechten Zylinders auf. Der Innenraum ist durch eine mittlere senkrechte, diametrale Trennwand 2 in zwei gleich große Halbräume 3 aufgeteilt und in jedem Halbraum ist mindestens eine Stoffaustauschpackung angeordnet, deren Außenseite ringsum einen definierten Randspalt von ca. 3 bis 30 mm mit der Innenseite der Außenwand 1 bildet. The columns for carrying out thermal separations and / or chemical reactions has an outer wall 1 in the form of a vertical cylinder. The interior is divided by a central, vertical, diametrical partition 2 into two half-spaces 3 of the same size and in each half-space at least one material exchange packing is arranged, the outside of which forms a defined edge gap of approx. 3 to 30 mm with the inside of the outer wall 1 .

Um zu verhindern, dass Flüssigkeit an der Innenseite entlangfließt, ohne die Stoffaustauschpackung zu erreichen, sind an der Außenseite der Stoffaustauschpackung zwei Randabweiser befestigt, die die entlangfließende Flüssigkeit zur Stoffaustauschpackung leiten.To prevent liquid on the inside flows along without reaching the mass transfer pack, are two on the outside of the mass transfer pack Edge deflector attached to the flowing along Pour liquid to the mass transfer packing.

Die zylindrische Kolonnenaußenwand 1 ist in zwei gleich große Halbschalen 1a, 1b geteilt, wobei die Trennung der Halbschalen entlang der Zylindererzeugenden verläuft.The cylindrical column outer wall 1 is divided into two half shells 1 a, 1 b of equal size, the separation of the half shells running along the ends of the cylinders.

Die Trennwand 2 aus Blech weist eine größere Breite auf als der Außendurchmesser der Kolonne, so dass die Trennwand zu beiden Seiten über die Außenseite der Kolonnenaußenwand mit senkrechten Seitenstreifen 12 vorsteht.The dividing wall 2 made of sheet metal has a greater width than the outside diameter of the column, so that the dividing wall protrudes on both sides beyond the outside of the outside column wall with vertical side strips 12 .

Die beiden Halbschalen 1a, 1b liegen mit ihren senkrechten Stirnseiten an den Seitenflächen der Trennwand nahe den senkrechten Trennwandrändern an, wobei ein schmaler Abstand zu den Trennwandrändern verbleibt, um die schmalen Seitenstreifen 12 zu bilden. Die außen vorstehenden Seitenstreifen 12 bilden mit den Trennwandhälften jeweils einen Zwickel, in dem eine Schweißnaht 13 einliegt. Die Schweißnähte können innen und/oder außen angeordnet sein. In einer weiteren Alternative können die senkrechten Ränder (Kanten) der Trennwand 2 im Bereich der Dicke (Breite, Stirnseite) der Kolonnenaußenwand enden.The two half-shells 1 a, 1 b rest with their vertical end faces on the side surfaces of the partition near the vertical partition edges, with a narrow distance from the partition edges remaining to form the narrow side strips 12 . The side strips 12 projecting from the outside each form a gusset with the partition wall halves, in which a weld seam 13 lies. The weld seams can be arranged inside and / or outside. In a further alternative, the vertical edges (edges) of the dividing wall 2 can end in the region of the thickness (width, end face) of the outer column wall.
