Abstract

EL INVENTO SE REFIERE A UN METODO Y UN EQUIPO PARA EL TRATAMIENTO DE UNA CORRIENTE LIQUIDA (A) PARA SER LIMPIADA E INTRODUCIDA EN UNA INSTALACION DE FLOTACION O EQUIVALENTE. EN EL METODO UNA PARTE DE LA CORRIENTE LIQUIDA (A) A LIMPIAR QUE FLUYE A LO LARGO DE LA LINEA DE FLUJO (11), O EL LIQUIDO LIMPIO QUE SALE DE LA INSTALACION DE FLOTACION, SE PASA A LO LARGO DE UNA PRIMERA RAMA (12) COMO UNA CORRIENTE LIQUIDA (A{SUB,1}) A UNA BOMBA (15). LA CAPACIDAD DE SUCCION DE LA BOMBA (15) ESTA REGULADA PARA QUE LA BOMBA (15) SUCCIONE GAS COMO UNA CORRIENTE (B), EL GAS (B) QUE HA SIDO SUCCIONADO POR LA BOMBA (15) ES MEZCLADO CON LA CORRIENTE LIQUIDA (A{SUB,1}) FLUYENDO EN LA PRIMERA RAMA (12), Y LA POSTERIOR MEZCLA DEL GAS Y DEL LIQUIDO TIENE LUGAR EN EL TUBO DE IMPULSION (16) DE LA BOMBA (15) . EL FLUJO MIXTO (E) DE GAS Y LIQUIDO SE PASA A LO LARGO DEL TUBO DE IMPULSION (16) DE LA BOMBA (15) A UNA PARTE DE MEZCLADO (17), DONDE EL TUBO DE IMPULSION (16) DE LA BOMBA (15) ACABA EN UNA DESCARGA DE PRESION (21). EL RESTO DE LA CORRIENTE LIQUIDA (A) A LIMPIAR SE PASA A LO LARGO DE UNA SEGUNDA RAMA (18) COMO UNA CORRIENTE LIQUIDA (A{SUB,2}) A LA PARTE DE MEZCLADO (17), DONDE LA CORRIENTE LIQUIDA (A{SUB,2}) QUE FLUYE A LO LARGO DE LA SEGUNDA RAMA (18) SE MEZCLA CON LA CORRIENTE LIQUIDA (E) QUE FLUYE EN EL TUBO DE IMPULSION (16) DE LA BOMBA (15), EN CUYO CASO, EN LA PARTE DE MEZCLADO (17), FUERA DE LA CORRIENTE (K), QUE ES LIBERADA DE LA DESCARGA DE PRESION (21), LAS BURBUJAS DE GAS EN LA CORRIENTE LIQUIDA (K) QUE CONTIENE GAS DISUELTO (B) SE LIBERAN. LA CORRIENTE LIQUIDA (K) LIBERADA DE LA PARTE DE MEZCLADO (17) SE PASA COMO UNA CORRIENTE (F) A LO LARGO DE UN CONDUCTO MEZCLADOR (22) HACIA EL INTERIOR DE LA LINEA DE FLUJO (11) DE LA CORRIENTE LIQUIDA (A) PARA SER LIMPIADA Y POSTERIORMENTE COMO UNA CORRIENTE (C ) HACIA LA INSTALACION DE FLOTACION O EQUIVALENTE.
