Description

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.

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.

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.  

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.

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.

An embodiment of the invention is in the drawing shown and is described in more detail below.

Show it:

Fig. 1: A horizontal cross section through the column and

Fig. 2: A section A of Fig. 1 on an enlarged scale.

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 .

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.

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.

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 .

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.

Claims (3)
