"Diffusion Separator"

The innovation deals with a diffusion separation device according to the features of the preamble of claim 1.

In chemical engineering, it is known to purify gaseous or liquid substances by using suitable Separating devices are passed through. These have, for example, a semi-permeable membrane that is made of suitable materials be kept at a distance. If a substance to be cleaned is introduced into such a separating device, one component, which can diffuse through the semi-permeable membrane, removed behind this as cleaned, while the impurities be discharged with the cleaning liquid or gas. Disadvantages of the known cutting devices are theirs complex construction, an unfavorable exchange area / volume ratio and a low rate of permeation.

The task underlying the innovation is to be seen in a compact, universally applicable and a high permeation rate to create having diffuse ion separator. 20th

To solve this problem are used in the characterizing part of the claim listed features.

The particular advantage of the diffusion device after the innovation is in its simple structure, its suitability for relatively high pressures and a high exchange surface / volume ratio.

In the drawing, an embodiment is shown according to the innovation, namely show

Figure 1 is a longitudinal section and

^ igur 2 a cross section through the cutting device.

A capillary membrane is an essential part of the diffusion separator 1 with capillaries 2 running in the longitudinal direction. One end of the membrane 1 is through a slot 4 of a central tube 5 put through and together with the beginning of an equivalent Tape made of a permeable fabric 3, for example glass fiber fabric, pressure-resistant to this «fixed. The capillaries 2 thus open radially into the interior 6 of the central tube 5.

The outer end of the wrap, i.e. H. the end of the capillary film 1 becomes fixed by means of adhesive 7 on the winding and at the same time the capillaries closed. The coil is on the central tube near the top and attached lower end.

After making this winding from the capillary membrane 1 and the glass fiber fabric tape 3, this is made of a bottom 8 and a casing 9 existing housing used and the central tube 5 firmly connected to the ground. Then a lid 10 is on the Housing jacket 9 placed and glued to this. The lid 10 has an opening 11 for the access of the substance to be cleaned, for example raw gas, and a further opening 12 for the removal of the portion of the raw gas that does not pass through the roll is passed through.

When the raw gas through the opening 11 into the interior of the housing is introduced, it will penetrate the glass fiber fabric 3 and pass through the semipermeable membrane wall into the capillaries 2. Here it is moved in the direction of the central pipe 5 and removed from it as purified, so-called new gas.

With this diffusion separation device, in particular the medium power range with a throughput can be achieved with low production costs can be tapped by a few liters per minute. Since the size of the exchange area is very favorable in relation to the volume, a high throughput can be achieved.
