Abstract
A cell frame for a bipolar electrolytic filter press cell includes an electrolysis-associated lower section and a gas disengagement or diverting upper section. A pressure bar extends across the cell frame immediately above the lower section to prevent distortion of the separator by cathode generated gases, and to promote disengagement of the gases. The frame, also, includes external headers in the upper section for collection of the gases evolved by the electrolysis of the electrolytic solutions.
Claims15
A cell frame for a bipolar electrolytic filter press cell, comprising:
- a. a peripheral rim,
- b. a first linear section defining a central web recessedly disposed within the rim, one side of the web defining a catholyte side and the other an anolyte side,
- c. a U-shaped section integrally formed with the linear section and cooperating therewith to define a recessed area communicating with the anolyte side above the first linear section, the recessed area extending away from the anolyte side of the central web,
- d. the portion of the frame extending from the top of the central web downwardly defining a lower zone at which electrolysis is carried out,
- e. the portion of the frame extending upwardly from the top of the central web defining an upper zone for disengagement the electrolysis-generated gases, and
- f. means for preventing distortion of the central web and facilitating disengagement of the gases disposed between the upper zone and the lower zone on the anolyte side of the frame.
In a chlor-alkali bipolar electrolytic filter press cell frame having a central web, a pressure bar therefor comprising:
- a. an elongated member having a length substantially equal to the width of the web of the cell frame, and
- b. a plurality of spacers extending outwardly from the elongated member, the spacers maintaining a predetermined distance between the elongated member and the frame.
In combination with a cell frame having a central web for a bipolar electrolytic filter press cell, a pressure bar for preventing distortion of the frame and for facilitating disengagement of the gases evolved in the cell, the pressure bar comprising:
- a. an elongated member having a length substantially equal to the width of the web of the cell frame, and
- b. a plurality of spacers extending outwardly from the elongated member, the spacers maintaining a pre-determined distance between the elongated member and the frame.
