Abstract

Plural concentric, tubular electrodes are disposed in a cylindrical pressure vessel to establish therein plural, at least, partially serially connected cells in radial, spaced-apart relation. The tubular electrodes are either mounted in an insulative bottom layer of the vessel, or when closed at their lower axial ends, are nested with spacers inbetween. Various provisions are made for cooling and for equalizing the electric current density in the several cells or the volume of the cells is kept similar.

Claims

1. Electrolysis device with plural electrolytic cells, comprising:

a vessel with cylindrical wall and discharge outlet for gas;

a plurality of concentrically arranged tubular electrodes, disposed in the vessel and concentric thereto, and defining plural annular concentric cells, each being open at the top so that a collecting chamber for a mixture of hydrogen and oxygen is defined above all of said cells in the upper portion of the vessel serving as collection chamber for a gas mixture to be discharged from the chamber via said outlet, the the annular cells being adapted to be filled with electrolytic liquid whereby each tube serves as anode of one and cathode of the radially next cell; and

insulating means for embedding bottom portions of the tubular electrodes thereby mounting the electrodes in relation to each other and to the vessel.

2. Device as in claim 1, the vessel having a bottom provided with an insulating layer, the lower ends of the tubes being open, but embedded in said layer to close each tube at the bottom thereby closing the bottoms of the ring spaces.

3. Device as in claim 2, wherein the vessel has a flat bottom, the radial spacing between respective two adjacent ones of the tubes decreasing in radial outer direction.

4. Device as in claim 2, wherein the vessel has a curved bottom, the tubes differing in length and being equidistantly spaced in radial direction.

5. Device as in claim 1, wherein the innerost tube is closed at its bottom, and means for feeding coolant to the innermost tube and discharging coolant therefrom.

6. Device as in claim 1, wherein all tubes are closed at the bottom and nested into each in spaced-apart relation, with insulating spacers inbetween serving as the said insulating means.

7. Device as in claim 6, and including a lid on the vessel, the innermost tube being closed and suspended from the lid, and passed through by a coolant.

8. Device as in claim 1, wherein the vessel is the outermost electrode to be connected to one terminal of a voltage source, and means for providing for insulated current lead-in to one of the tubes in the vessel.

9. Device as in claim 6, said bottoms being flat, the spacers being of angular configuration.

10. Device as in claim 1, the tops of the electrode tubes being in a common plane.
