Electrolysis device
An electrolysis device for the electrolytic treatment of liquids has an anode chamber and a cathode chamber which are separated from one another via an ion exchange membrane. The chambers are provided with an inlet opening and an outlet opening for the flowing electrolyte, each with one electrode. The inner space of the anode chamber and/or of the cathode chamber are/is subdivided by webs or ribs extending transversely with respect to the electrodes. The webs or ribs are provided at least regionally with holes or cut outs. The webs or ribs include at least one lower region free of holes or cut outs. The electrolysis device provides sufficient mixing in the upper foam phase in the longitudinal direction and also at the same time the airlift pump effect is maintained by way of ascending gas bubbles in the lower region.
1. An electrolysis device for the electrolytic treatment of liquids, the device comprising:
an anode chamber including at least one inlet opening and one outlet opening configured to permit the flow of electrolyte and with at least one electrode;
a cathode chamber including at least one inlet opening and one outlet opening configured to permit the flow of electrolyte and with at least one electrode; and
an ion exchange membrane separating the anode chamber from the cathode chamber;
wherein the inner space of the anode chamber and/or of the cathode chamber are/is subdivided by webs extending transversely with respect to the electrodes,
wherein the webs are provided at least regionally with holes, and wherein the webs extend in the height direction of the electrolysis device and comprise, as viewed in the height direction, at least one lower region in which the webs are free of holes.
2. The electrolysis device of claim 1 wherein the webs comprise, as viewed in the height direction, at least one upper region with holes.
3. The electrolysis device of claim 1 wherein the lower region, in which the webs are free of holes, extends at least approximately over the lower half of the entire height of the webs.
4. The electrolysis device of claim 1 where the lower region, in which the webs are free of holes, extends at least approximately over the lower two thirds of the entire height of the webs.
5. The electrolysis device of claim 1 wherein the upper region, in which the webs comprise holes, extends at least approximately over the upper quarter of the entire height of the webs.
6. The electrolysis device of claim 1 wherein the upper region, in which the webs comprise holes, extends at least approximately over the upper third of the entire height of the webs.
7. The electrolysis device of claim 2 wherein the webs comprise, in the at least one upper region, multiple holes which are spaced apart from one another by solid regions in the height direction of the webs.
8. The electrolysis device of claim 2 wherein the webs at least partially have, in the at least one upper region, holes which have an approximately circular contour.
9. The electrolysis device of claim 2 wherein the webs comprise, in the at least one upper region, multiple holes which, as viewed in the direction of the height of the webs, have different spacings from one another.
10. The electrolysis device of claim 9 wherein the holes in the webs, in a first lower section of the upper region, are arranged with smaller spacings from one another than in a second section of the upper region adjoining a top thereof.
11. The electrolysis device of claim 1 wherein the free cross section of at least one of the holes is at least approximately 10 mm 2 .
12. The electrolysis device of claim 1 wherein the free cross section of at least one of the holes is at least approximately 15 mm 2 .
13. A method comprising electrolytic treatment of a flowable medium in the electrolysis device of claim 1 .
14. The method of claim 13 wherein the method comprises chlor-alkali electrolysis.
