LEAK CURRENT PREVENTING METHOD IN ELECTRODE REACTION EQUIPMENT

摘要

PURPOSE:To increase electric resistance in a passage and prevent leak current by mixing bubbles to a liquid in an electrolyte path connecting between cells. CONSTITUTION:An electrolytic bath is constructed with a positive chamber 1 and a negative chamber 2 which are stacked in series with a separator interposed, a main pipe 4 which supplies electrolyte 3 to the positive and negative chambers, and a branch pipe 12 and a branch pipe 5A which are branched from the main pipe 4. Bubbles are fed to the main pipe 4 in such a way that a gas supply pipe 8A which is connected to a gas cylinder 8 is inserted into a electrolyte path (main pipe) 4, or a set of electrodes 11 are faced in a path 10 of the electrolyte 3 and gas is directly generated and mixed to the electrolyte. The main pipe 4 is arranged above an electrolyte inlet of a unit cell. When electrolyte is supplied through U-shaped pipe which connects the main pipe 4 to the unit cell, bubbles are trapped with the U-shaped pipe to prevent entering to the unit cell.
