Abstract

SE PRESENTA UN DIFUSOR DE PRESION MULTINIVEL (10) PARA TRATAR PASTA DE PAPEL O UN MATERIAL FIBROSO CELULOSICO TRITURADO SIMILAR. DOS SUBVOLUMENES DIFERENTES (16, 17) QUEDAN DEFINIDOS DENTRO DE LA PANTALLA ANULAR (15) DEL DIFUSOR DE PRESION MEDIANTE UN TABIQUE TUBULAR (40) QUE CUELGA CERCA DE LA PARTE SUPERIOR DEL RECIPIENTE Y UNA PARED TRANSVERSAL (43) CERCA DE LA MITAD DEL RECIPIENTE. SE INTRODUCE UN LIQUIDO PARA LAVAR EN EL NIVEL SUPERIOR (A TRAVES DE 22, 23), EL LIQUIDO EXTRAIDO PASA A TRAVES DEL FONDO DEL TABIQUE Y SE EXTRAE A TRAVES DE UN ORIFICIO DE SALIDA PARA LOS LIQUIDOS (18) QUE SE ENCUENTRA EN LA PARTE SUPERIOR DEL RECIPIENTE. A CONTINUACION SE VUELVE A INTRODUCIR EL LIQUIDO EXTRAIDO EN EL NIVEL INFERIOR A MODO DE LIQUIDO DE LAVADO (A TRAVES DE 24, 25) Y EL LIQUIDO EXTRAIDO EN EL NIVEL INFERIOR SE DESCARGA DEL RECIPIENTE QUE SE ENCUENTRA EN EL FONDO (A TRAVES DE 19). EL EQUIPO DE PANTALLA SE PUEDE CERRAR EN EL AREA (15'') DE LA PARED TRANSVERSAL (43) DIVIDIENDO ASI LOS SUBVOLUMENES ENTRE SI PARA MINIMIZAR LA POSIBILIDAD DE QUE LOS FLUJOS DE EXTRACCION SE MEZCLEN EN LOS DIFERENTES NIVELES.
