Abstract
Apparatus usable in the electrolytic treatment of electroactive species in a solution include a porous electrode which is supported across a fluid flow path in such a manner that fluid flowing along the flow path must pass through an effective portion of the electrode.
Claims54
Apparatus usable in the electrolytic treatment of electroactive species in a solution, comprising a first electrode, said first electrode being fluid permeable so that a fluid may pass therethrough;
- supporting means surrounding all edges of said first electrode for supporting said first electrode across a fluid flow path and sealing said edges so that fluid flowing along said flow path must pass through an effective portion of said first electrode;
- a first chamber positioned on one side of said first electrode;
- a second chamber positioned on an opposite side of said first electrode from said first chamber;
- first inlet means in fluid communication with said first chamber for permitting a fluid to be supplied thereto;
- first outlet means in fluid communication with said second chamber for permitting a fluid to be discharged therefrom;
- means for flowing fluids from said first inlet means to said first outlet means through said electrode in a first direction;
- second inlet means in fluid communication with said second chamber for permitting fluid to be supplied thereto;
- second outlet means in fluid communication with said first chamber for permitting fluid to be discharged therefrom;
- and means for flowing fluid from said second inlet means to said second outlet means through said first electrode in a second direction opposite said first direction upon the termination of fluid flow in said first direction.
A reactor usable in the electrolytic treatment of electroactive species in a solution, comprising a plurality of cells, each of said cells including a first electrode which is fluid permeable, a second electrode positioned on one side of said first electrode, a third electrode positioned on the other side of said first electrode, supporting means surrounding all edges of said first electrode for supporting said first electrode across a fluid flow path and sealing said edges so that fluid flowing along said flow path must pass through an effective portion of said first electrode, a first diaphragm interposed between said first and second electrodes, a second diaphragm interposed between said first and third electrodes, a first chamber formed between said first electrode and said first diaphragm, a second chamber formed between said second diaphragm and said first electrode, a third chamber formed between said second electrode and said first diaphragm, and a fourth chamber formed between said second diaphragm and said third electrode;
- first supply means for permitting a first fluid to be supplied to the reactor;
- second supply means for permitting a second fluid to be supplied to the reactor;
- third supply means for permitting a third fluid to be supplied to the reactor;
- first discharge means for permitting a first fluid to be discharged from the reactor;
- second discharge means for permitting a second fluid to be discharged from the reactor;
- third discharge means for permitting a third fluid to be discharged from the reactor;
- first communicating means for providing fluid communication between said first supply means, said first chamber of each of said cells, said second chamber of each of said cells, and said first discharge means;
- second communicating means for providing fluid communication between said second supply means, said third chamber of each of said cells, said fourth chamber of each of said cells, and said second discharge means;
- and third communicating means for providing fluid communication between said third supply means, said first chamber of each of said cells, said second chamber of each of said cells, and said third discharge means.
