The metal production processes that are carried out in electrolytic cells, release gases into the environment that incorporate micro drops of the components of the electrolyte, from which metals are produced, one of whose components is generally an acid or a strong base. The difficulties that these gases with micro drops entail are varied and affect the operators, and production structures and equipment. Thus, the operators must protect their respiratory system by using masks and protect their eyes using glasses. The structures, as well as the equipment required for the process and the manipulation of supplies and products, suffer corrosion. The measures that are currently adopted to mitigate the problems consist of placing spheres of polypropylene on the surface of the electrolyte or adding surfactants, which bring problems in the solvent extraction process, and the installation of extraction systems in the bay or in the cells, which in turn generate other problems as the surface of the cell remains in contact with the environment. This invention consists of confining in a compartmentalized manner the zone above the free surface of the electrolyte, by means of the insertion of an Anodic Confiner over each anode, with flexible lateral skirts that are sealed over the vertical faces of both electrodes when the cathodes are introduced in the cell, in which the ends of the confined volume face the orifices of perforated extraction ducts, located on both sides of the cell or of an anode and cathode support structure introduced in the interior of the Cell, ducts that are connected to the normal extraction system of the Production Bay, thus preventing the gases from reaching the environment. |
