Electrolytic cell constructed for high circulation and uniform flow of electrolyte
Abstract
Abstract Rapid circulation and uniform flow of electrolyte between flat plate electrodes arranged transversely of an electrolytic cell for electrorefining or electrowinning purposes are obtained by constructing the cell with a perforated baffle dividing an elongate and narrow electrolyte feed chamber along one side of the cell from the cell proper and with at least one vertical input pipe, having inflow orifices at intervals along its height and directed lengthwise of the feed chamber, for distributed input of electrolyte to such feed chamber. The electrodes are preferably deeply recessed intermediate their upper margins to provide an uninterrupted flow channel in the upper part of the cell and from end to end thereof.
