Claims
- 1. An electrode for a monopolar filter press cell which comprises:
- (a) a first foraminous surface and a second foraminous surface positioned in parallel and spaced apart;
- (b) a frame having two side members, a top member and a bottom member attached to said first foraminous surface and said second foraminous surface;
- (c) a chamber formed between said first foraminous surface and said secon foraminous surface and bounded by said frame;
- (d) at least one pair of conductor rods entering said chamber through openings in one of said side members of said frame, one of said pair of conductor rods being attached only to said first foraminous surface and the other of said pair of conductor rods being attached only to said second electrode surface, each conductor rod having a lead portion outside of said chamber suitable for attachment to a current supply means and a support portion inside said chamber for said attachment to said electrode surface; said openings being substantially centered in said side frame member, and said support portion of each of said conductor rods being bent toward said electrode surface to which said conductor rod is attached; and
- (e) inlets and outlets in said frame for introducing fluids into and removing electrolysis products from said chamber.
- 2. The electrode of claim 1 in which the height of said electrode is from about 1 to about 5 meters.
- 3. The electrode of claim 2 in which from about 2 to about 12 pairs of conductor rods are attached to said first and said second electrode surfaces.
- 4. The electrode of claim 3 in which each said pair of conductor rods are positioned substantially opposite each other.
- 5. The electrode of claim 3 in which one of said pair of conductor rods is positioned a spaced distance above the other conductor rod.
- 6. The electrode of claim 4 or claim 5 in which said support portion of said conductor rod is substantially horizontal.
- 7. The electrode of claim 4 or claim 5 in which said support portion is sloped at from about 2.degree. to about 10.degree. from the horizontal.
- 8. The electrode of claim 6 in which one of said pair of conductor rods is above and spaced apart a distance of from about 0.025 to about 0.100 meters from the other of said pair.
- 9. The electrode of claim 8 in which the ratio of height to thickness of said electrode is from about 20:1 to about 50:1.
- 10. In a monopolar filter press cell for the electroylsis of salt solutions having a plurality of anodes and cathode alternatingly interleaved and a cation exchange membrane between each anode and each cathode, the improvement which comprises employing as anodes the electrode of claim 9.
- 11. In a monopolar filter press cell for the electroylsis of salt solutions having a plurality of anodes and cathodes alternatingly interleaved and a cation exchange membrane between each anode and each cathode, the improvement which comprises employing as the cathodes the electrode of claim 9.
