System for confining and evacuating aerosols of two or three - phases

摘要

In electrolytic cells for metal production the zone above the free surface of the electrolyte is confined in a compartmentalized manner by means of the insertion of an Anodic confiner over each anode with lateral flexible skirts (2) that are sealed over the vertical faces of both electrodes when the cathodes are introduced in the cell. The ends of the confined volume face the orífices 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. The ducts that are connected to the normal extraction system of the production bay, thus preventing the gases containing micro drops of an acid or strong base components of the electrolyte from reaching the environment.
