Abstract
In a filter press membrane electrolytic cell there is provided a reinforced electrode frame channel that is backed by a reinforcing strip which also serves as a gasket restraint when the adjacent electrodes are compressed to form the assembled cell.
Claims18
In a frame for an electrode utilized in a filter press membrane cell and adapted to have opposing electrode surfaces connected thereto and which are adjacent membranes in an assembled filter press membrane cell comprising:
- a. a base portion of predetermined thickness and predetermined length having a first side and a second side;
- b. a first leg connected to the first side of the base portion and adapted to have foraminous electrode surface means fixedly fastened thereto;
- c. a second leg connected to the second side of the base portion, the second leg combining with the base portion and the first leg to be of an assembled predetermined width and adapted to have foraminous electrode surface means fixedly fastened thereto;
- and
- d. reinforcing means fixedly fastened to the base portion to strengthen the frame against compressive force applied against the first and second legs adjacent the base portion and being of a second width greater than the assembled predetermined width.
In an electrode for use in a filter press membrane cell designed to be compressively assembled with a predetermined number of electrodes separated by gasket means and membrane means comprising:
- (a) electrode frame means of predetermined thickness having a base portion connecting two opposing leg portions, each leg portion having a gasket receiving surface against which the gasket means is placed during cell assembly;
- (b) first electrode surface means fixedly fastened to one of the two opposing leg portions;
- (c) second electrode surface means fixedly fastened to the second of the two opposing leg portions;
- and
- (d) reinforcing means fixedly fastened to the base portion and forming a void with the base portion into which the gasket means may deform during cell assembly.
In an electrode having a frame, the electrode being utilized in a filter press membrane cell comprising:
- (a) a base portion of predetermined thickness and predetermined length having a first side and a second side;
- (b) a first leg connected to the first side of the base portion;
- (c) a second leg connected to the second side of the base portion, the second leg combining with the base portion and the first leg to be of an assembled predetermined width;
- (d) reinforcing means fixedly fastened to the base portion to strengthen the frame and being of a second width greater than the assembled predetermined width;
- and
- (e) foraminous electrode surface means fixedly fastened to the first leg and the second leg.
In an electrode having a frame, the electrode being utilized in a filter press membrane cell comprising:
- (a) a base portion of predetermined thickness and predetermined length having a first side and a second side;
- (b) a first leg connected to the first side of the base portion, the first leg being at least partially indented to form an electrode surface-receiving area;
- (c) a second leg connected to the second side of the base portion and being at least partially indented to form an electrode surface-receiving area, the second leg combining with the base portion and the first leg to be of an assembled predetermined width;
- (d) reinforcing means fixedly fastened to the base portion to strengthen the frame and being of a second width greater than the assembled predetermined width;
- and
- (e) foraminous electrode surface means fixedly fastened to the at least partially indented electrode surface-receiving area of the first leg and the second leg.
A filter press membrane electrolytic cell with anolyte and catholyte infeed and outlet lines, product outlet lines, and anolyte and catholyte gas-liquid disengagers, comprising:
- (a) a plurality of cathodes, each cathode having a frame with at least a base portion and first and second leg portions attached to opposing ends of the base portion;
- (b) a plurality of anodes, each anode being positioned between a pair of cathodes and having a frame with at least a base portion and first and second leg portions attached to opposing ends of the base portion;
- (c) a plurality of ion-selective membranes, each membrane being interpositioned between an adjacent anode and cathode;
- (d) sealing means positioned between each cathode, interpositioned membrane and anode;
- (e) reinforcing means attached to the base portion of each anode frame and cathode frame to reinforce each anode frame and cathode frame against the compressive forces that are exerted during assembly and operation of the cell;
- and
- (f) compression applying and retaining means to compress and secure the cell in an assembled state directing the compression forces along the reinforcing means.
