Abstract

UN PROCEDIMIENTO PARA FILTRADO Y ENJUAGADO DE PARTICULAS SOLIDAS A PARTIR DE LIQUIDOS TRABAJA CON UN TAMBOR (5) DE FILTRADO DISPUESTO DE FORMA COMPLETA DEBAJO DEL NIVEL (6) DEL LIQUIDO, CUYA SUPERFICIE (7) DE CUBIERTA ESTA EQUIPADA CON UN MEDIO (8) DE FILTRADO Y ES RECORRIDA DESDE EL EXTERIOR HACIA EL INTERIOR. SE HA PREVISTO UN DISPOSITIVO DE REENJUAGUE PARA LA ELIMINACION DE LA TORTA DE FILTRADO A PARTIR DEL MEDIO (8) DE FILTRACION. PARA EL COMIENZO DE CADA CICLO DE REENJUAGUE SE INTRODUCE EN EL TAMBOR (5) DE FILTRO UN ACOLCHADO (15) DE AIRE Y CON ELLO SE DESPLAZA EL LIQUIDO EN EL TAMBOR (5) DE FILTRADO DE TAL MODO, QUE A TRAVES DE UN EQUIPO (19) DE INYECCION DISPUESTO EN EL INTERIOR DEL TAMBOR (5) DE FILTRADO SIN DISPOSICION DE ESTANQUEIDAD, SE INYECTA UN LIQUIDO CON UN CABEZAL (17) DE INYECCION A TRAVES DEL ACOLCHADO (15) DE AIRE HACIA EL LADO POSTERIOR DE LA SUPERFICIE (7) DE CUBIERTA DEL TAMBOR (5) DE FILTRADO. LAS TORTAS DE FILTRADO DISUELTAS SE GUIAN HACIA EL EXTERIOR A PARTIR DE LACORRIENTE DEL LIQUIDO SEGUN LA FLECHA (22).
