摘要： The invention describes an anodic structure for electrolysis cell provided with a separator, in particular for a diaphragm chlor-alkali electrolysis cell, consisting of at least one movable surface suited to be put in contact with the separator. The movable surface comprises a component of higher thickness in contact with a porous layer of lower thickness, for instance a thin sheet provided with openings, and is characterised by the fact that a catalytic coating is applied only to the porous layer of lower thickness. The component of higher thickness has a substantially planar development and includes elements capable of promoting the local recirculation of electrolyte.

摘要： Operation of diaphragm monopolar electrolyzers for chlor-alkali electrolysis is improved by providing at least part of the anodes in their upper portion with hydrodynamic baffles capable of generating a plurality of lifting and downcoming recirculation motions of the mixed anolyte-gas phase and of the anolyte separated from gas, respectively, which baffles are characterized by their superior edge or overflow holes located under the free surface of the anolyte, resulting in a reduction of the cell voltage and an increase in the faradic efficiency and the quality of the products.

摘要： The invention relates to an amalgam decomposer for mercury cathode chlor-alkali cells. The amalgam decomposer of the invention contains a filling of carbon steel rings whose external surface is provided with a catalytic coating for amalgam decomposition consisting of one or more electrically conductive metals carbides. The internal surface of the rings is free of catalytic coating and wettable by the amalgam, while the external carbide catalytic coating is not wettable by the amalgam thereby favouring hydrogen evolution.

摘要： The invention discloses a novel structure for an expandable anode to be used in diaphragm cells. This new structure comprises a conductor bar in the form of a copper core provided with a titanium layer having a first and a second pair of flexible expanders fixed thereto. The welding points of the second pair of expanders are positioned orthogonally with respect to the welding points of the first pair of expanders along the circumference of the conductor bar. Also the anode surfaces are connected by welding points to the pairs of expanders. The anode of the invention may be both a new anode and a conventional existing anode having only a first pair of expanders whereto the second pair of expanders is attached. With the device of the present invention the ohmic drop between the conductor bar and the anode surface is substantially decreased and further there is no risk of damaging the interface between the copper core and the titanium coating by an excessive thermal stress, due to the welding procedures.
