Abstract
A horizontal electrolyzer comprises a mercury cathode, an anode located above the cathode and an inclined diaphragm separating the cathode from the anode, the cathode, diaphragm and anode being substantially parallel. The cathode consists of mercury flowing longitudinally in a plurality of channels which are vertically offset with respect to each other.
Claims15
A horizontal mercury cathode electrolyzer comprising:
- a housing,
- diaphragm means separating a lower cathode compartment and an upper anode compartment in said housing,
- a plurality of parallel channels located in said cathode compartment and inclined at a slight longitudinal angle to the horizontal, said channels being vertically staggered with respect to each other,
- means for delivering mercury to the upper end of each of said channels and for collecting and evacuating said mercury at the lower end of each said channel,
- and anode means in said anode compartment,
- said diaphragm means being approximately parallel to a plane passing through the longitudinal midlines of said channels and to said anode means.

In an electrolyzer for chemically reducing ions in solution,
- a substantially horizontal housing,
- diaphragm means separating a lower cathode compartment and an upper anode compartment in said housing and having a first slope with respect to horizontal in a first longitudinal direction of said housing and a second higher slope in a second transverse direction of said housing,
- a plurality of parallel channels located in said cathode compartment in said longitudinal direction and each having said first slope, said channels being vertically staggered with respect to each other for their longitudinal midlines to be in a plane approximately parallel to the diaphragm means,
- means for delivering mercury to the upper end of each of said channels and collecting and evacuating mercury at the lower end of each of said channels,
- anode means located in said anode compartment substantially parallel to said diaphragm means,
- means for circulating a solution of the ions to be reduced in said longitudinal direction throughout said cathode compartment in the same direction as said mercury,
- and means for circulating a liquid anolyte longitudinally in said anode compartment.
