Abstract

DISPOSITIVO PARA LA DESALINIZACION ELECTROQUIMICA CONTINUA DE SOLUCIONES ACUOSAS EN FORMA DE UN MODULO WIKKEL CON UN ELECTRODO CENTRAL 1, ALREDEDOR DEL CUAL ESTAN ENROLLADAS UNA MEMBRANA INTERCAMBIADORA DE ANIONES Y UNA MEMBRANA INTERCAMBIADORA DE CATIONES 6, ASI COMO UN ELECTRODO OPUESTO EXTERIOR 1. LAS MEMBRANAS 6 ESTAN CERRADAS EN SU BORDE INTERIOR Y EN SU BORDE EXTERIOR CON UN DISPOSITIVO DE APRIETE EN CADA BORDE DE TAL MODO, O ANCLADAS EN UN MOLDE RESINA DE PLASTICO 2 DE TAL MODO, QUE SE DEFINE UN CAMARA DE DILUCION 7 Y UNA CAMARA DE CONCENTRACION. LA CAMARA DE DILUCION Y/O LA CAMARA DE CONCENTRACION PUEDEN CONTENER EN CASO DE QUE SE DESEE UNA RESINA INTERCAMBIADORA DE IONES. EL ELECTRODO CENTRAL Y EL CONTRAELECTRODO EXTERIOR 1, PUEDEN PRESENTAR, ADEMAS, UN REBAJE PARA EL ALOJAMIENTO DEL DISPOSITIVO DE APRIETE INTERNO O DEL BLOQUE DE RESINA SINTETICA INTERNA 2, CON EL FIN DE ALCANZAR UN ENROLLADO DE SECCION A SER POSIBLE EN FORMA DE ESPIRAL.
