Abstract

Die Erfindung betrifft eine Vorrichtung zur Spaltung von Öl-in-Wasser-Emulsionen und Regeneration von Reinigungs- und Entfettungsbädern mittels Elektrokoagulation. Die Vorrichtung zur Regeneration von Reinigungs- und Entfettungsbädern insbesondere durch Spaltung in einer elektrophysikalischen Zelle (3) ist insbesondere dadurch gekennzeichnet, daß mindestens zwei voneinander unabhängige Elektrodeneinrichtungen (1, 2) mit jeweils einem eigenen von den anderen unabhängigen und getrennt regelbaren Stromkreis (7-10) angeordnet sind. Auf diese Weise können sowohl die Bildung der Koagulationskerne als auch der Prozeß der Elektrokoagulation unabhängig voneinander an die jeweiligen Betriebsverhältnisse angepaßt und optimiert werden. Die getrennten Stromkreise für die beiden Elektrodeneinrichtungen (1, 2) bieten die Möglichkeit, den Prozeß mit kleinen Elektrodenabständen, niedrigen Spannungen und hohen Stromdichten zur Bildung von Koagulationskernen an den löslichen Elektroden (2) und mit größeren Abständen, hohen Spannungen, hohen Feldstärken, kleinen Stromdichten und geringer Gasentwicklung beim Prozess der Elektrokoagulation an den beständigen Elektroden (1) zu betreiben.
