Metal production processes carried out in electrolytic cells release two-phase or three-phase aerosol flows into the environment, comprising microdrops of the electrolyte components from which the metals are produced, one of said components generally being an acid or a strong base. The complications of said aerosols are multiple and affect the production operators, structures and equipment. The operators must therefore protect their respiratory system by using masks and protect their eyes with glasses. The structures are affected by corrosion, as is the equipment required for the process and the handling of inputs and products. The measures currently taken to mitigate the problems involve placing expanded polystyrene spheres or other substances on the surface of the electrolytes, and installing extraction systems in the cells, which, in turn, generate other problems, as the surface of the cell remains in contact with the environment. The invention involves enclosing the upper area of the anodes by means of a sleeve of fabric open at the upper and lower ends thereof that are arranged inside single bells with lateral openings facing openings of perforated extraction ducts arranged on both sides of the cell, in a supporting structure of anodes and cathodes that are connected to the normal extraction system of the production plant, thereby preventing the aerosols from reaching the environment. |
