Abstract

The invention refers to a device for separation of emulsions by electrochemical precipitation in which metal ions for binding the emulsified compounds are supplied to the emulsion by electrolysis and which comprises a tubular sacrificial metal electrode (1), a counter-electrode (2) located in register with the end surface of the sacrificial electrode at a spacing (h) therefrom so as to form a gap (6), through which the emulsion is carried and which is maintained by means of spacers (5) mounted on said counter-electrode, the sacrificial electrode (1) engaging said spacers (5) with its end surface, current supply means (5, 9, 10) to the sacrificial electrode (1) and the counter-electrode (2) and a drive device (12, 13) for providing a mutual angular movement between said pair of electrodes (1, 2) around their axis of symmetry. In order to assure a really un-interrupted operation of the device while maintaining a structural simplicity thereof the invention suggests that the current supply means to the sacrificial electrode (1) comprise at least one metal member (5), isolatingly mounted and serving as spacer, said metal member simultaneously being adapted to provide a scraping action on oxides and contaminations on the active surface of said sacrificial electrode.
