Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE PROTECCION CATODICA PARA UN TANQUE DE ALMACENAMIENTO COLOCADO SOBRE EL SUELO QUE TIENE UN FONDO METALICO (20), TANTO PARA FONDOS NUEVOS COMO REEQUIPADOS. HAY COLOCADA UNA MEMBRANA DE SEGURIDAD DIELECTRICA (25), QUE CONTIENE RENDIJAS, A POCA DISTANCIA DE LA PARTE DE ABAJO Y QUE SE EXTIENDE POR DEBAJO DEL FONDO DEL TANQUE DE FORMA GENERALMENTE PARALELA AL MISMO FORMANDO UNA ENVOLTURA NO MUY ANCHA. ENTRE LA MEMBRANA Y EL FONDO DEL TANQUE, SOPORTANDO EL FONDO DEL TANQUE, HAY COLOCADO UN CONDUCTOR ELECTROLITICO COMPACTO (28) QUE TIENE EMBEBIDO UN ANODO DE PROTECCION CATODICA COLOCADO HORIZONTALMENTE (30) CON FORMA DE MATRIZ O DE REJILLA DE BARRAS DE TITANIO Y CINTAS INTERCONECTADAS (32). EN EL CONDUCTOR ELECTROLITICO PUEDE HABER EMBEBIDO UN AISLADOR DIELECTRICO RETICULADO (48) COLOCADO JUSTO ENCIMA DEL ANODO Y QUE SE PUEDE ACTIVAR PARA EVITAR QUE CUALQUIER PARTE DEL ANODO ENTRE EN CONTACTO CON EL FONDO DEL TANQUE Y PARA MANTENER UNA SEPARACION GENERALMENTEUNIFORME ENTRE EL ANODO Y EL FONDO DEL TANQUE. LAS CINTAS SE EXTIENDEN TRANSVERSALMENTE RESPECTO A LAS BARRAS Y ESTAN SOLDADAS POR PUNTOS EN CENTROS UNIFORMES A LAS BARRAS EN LOS DIAMETROS O CUERDAS MAYORES DEL FONDO DE UN TANQUE CON FORMA CIRCULAR. ENTRE LAS BARRAS Y LOS SUMINISTROS DE ENERGIA A UN RECTIFICADOR (42) HAY UN TIPO DE CONEXION EXTRAPLANA (37) Y EN TANQUES CON GRANDES FONDOS HAY UNA MULTIPLICIDAD DE CONEXIONES DE ESTE TIPO SEPARADAS ESTRATEGICAMENTE. DE MODO PARECIDO, SE PUEDEN COLOCAR UNA PLURALIDAD DE CELDAS DE REFERENCIA (34) TANTO PARA EL LUGAR COMO PARA EL TIPO, QUE HACEN QUE HAYA SUMINISTROS DE ENERGIA REDUNDANTES Y CELDAS DE REFERENCIA. EL ANODO SE FORMA A BASE DE DESENROLLAR, COLOCAR Y CONECTAR LAS BARRAS Y LAS CINTAS EN UNA CAPA COMPACTA DE UN CONDUCTOR ELECTROLITICO SOBRE EL REVESTIMIENTO. UNA VEZ CONECTADOS LOS CONDUCTORES Y GUIADOS HACIA EL RECTIFICADOR EXTERNO, SE PUEDE COLOCAR EL AISLADOR ENCIMA DE LA REJILLA DE ANODO. UN CONDUCTOR ELECTROLITICO COMPACTO ADICIONAL RELLENA LAS ABERTURAS QUE HAY EN EL AISLADOR.
