Abstract

EL PRESENTE INVENTO SE REFIERE A UN APARATO PARA FILTRAR Y EL PROCEDIMIENTO DE LAVADO DEL MISMO. EL APARATO ES DE CIRCULACION ASCENDENTE DEL FLUIDO A TRATAR EN UN RECINTO (7) CERRADO EN AL MENOS UNO DE SUS EXTREMOS (15) Y CONTIENE UN LECHO FLOTANTE FIJO DE PARTICULAS DE FILTRADO (16) DE DENSIDAD INFERIOR A LAS DEL FLUIDO A TRATAR. EL APARATO SE CARACTERIZA EN QUE LA TUBERIA (3) DE EVACUACION DE LAS MATERIAS EN SUSPENSION FILTRADAS TIENE FORMA DE LIRA CON RESPIRADERO (5) Y UNA DIMENSION QUE PERMITE EL VACIADO DE LA COLUMNA DE FLUIDO CONTENIDO EN EL RECINTO A UNA VELOCIDAD SUPERIOR A LA VELOCIDAD MINIMA DE FLUIDIFICACION. LAS PARTICULAS DE FILTRADO TIENEN UNA MASA VOLUMETRICA PARTICULAR, COMPRENDIDA ENTRE 5 KG/M3 Y 500 KG/M3, Y UN TUBO DE ALIMENTACION (1) DEL FLUIDO A TRATAR ESTA SITUADO EN UNA ZONA DEL EXTREMO INFERIOR DEL RECINTO Y POR DEBAJO DEL NIVEL INFERIOR DEL LECHO FLOTANTE FIJO Y POR ENCIMA DEL NIVEL SUPERIOR DEL TUBO DE EVACUACION (3) DE LA SUCIEDAD.
