Abstract

Los procesos de producción de metales que se realizan en celdas electrolíticas, liberan al ambiente gases que incorporan micro gotas de los componentes del electrolito, a partir del cual se producen los metales, uno de cuyos componentes generalmente es un ácido o una base fuerte. Las dificultades que acarrean estos gases con micro gotas son variadas y afectan a los operadores, estructuras y equipos de producción. Así, los operadores deben proteger su sistema respiratorio mediante el empleo de máscaras y proteger sus ojos usando gafas. Las estructuras sufren corrosión, así como también los equipos requeridos para el proceso y la manipulación de insumos y productos. Las medidas que se adoptan actualmente para mitigar los problemas, consisten en colocar en la superficie de los electrolitos esferas de polipropileno, o agregar surfactantes, que traen problemas en el proceso de extracción por solventes, e instalar sistemas de extracción en la nave o en las celdas, los que a su vez generan otros problemas, ya que la superficie de la celda permanece en contacto con el ambiente. La presente invención, consiste en confinar de manera compartimentada la zona sobre la superficie libre del electrolito, mediante la inserción sobre cada ánodo de un Confinador Anódico, con faldas flexibles laterales que se sellan sobre las caras verticales de ambos electrodos al introducir los cátodos en la celda, en que los extremos del volumen confinado se enfrentan a los orificios de ductos perforados de extracción, ubicados a ambos lados de la celda o de una estructura soportante de ánodos y cátodos introducida en el interior de la Celda, ductos que se conectan al sistema normal de extracción de la Nave de Producción, impidiendo así que los gases lleguen al ambiente.
