Abstract

LA PRESENTE INVENCION SE REFIERE A UN METODO PARA EXTRAER DE UN LIQUIDO, FILTRANDOLO, AL MENOS UNA SUSTANCIA SOLIDA CONTENIDA EN EL MISMO, SOBRE TODO POR MEDIO DE FILTROS DE FORMA TUBULAR. EL REFERIDO METODO CONSTA, DE MODO CONSECUTIVO, DE LAS SIGUIENTES FASES: SE SUMINISTRA EL FLUIDO REFERIDO QUE CONTIENE LA SUSTANCIA DE QUE SE TRATA , POR MEDIO DE UN SUMINISTRO AXIAL, AL ELEMENTO DE FILTRADO; SE FILTRA EL FLUIDO REFERIDO QUE CONTIENE LA SUSTANCIA REFERIDA DONDE LA REFERIDA SUSTANCIA PERMANECE EN EL MEDIO DE FILTRADO COMO UN RESIDUO; SE DEJA ESCAPAR EL FLUIDO REFERIDO, Y SE ELIMINA EL REFERIDO RESIDUO POR UNA DESCARGA AXIAL QUE SE PUEDE CERRAR, OPUESTA AL MEDIO DE SUMINISTRO REFERIDO FUERA DEL FILTRO SUSODICHO, DONDE SE COMPRIME UNA CANTIDAD PREFIJADA DE RESIDUO EN FORMA DE BARRA SOLIDA POR EFECTO DE LA PRESION EN EL FLUIDO SUMINISTRADO DE REFERENCIA, CUANDO SE EFECTUA EL FILTRADO; SE ABRE LA DESCARGA APTA DE CIERRE ANTES MENCIONADA EN UN MOMENTO DETERMINADO DE ANTEMANO; Y, FINALMENTE, SERETIRA LA ANTEDICHA BARRA POR EL EFECTO DE LA PRESION EJERCIDA SOBRE DICHA BARRA POR EL FLUIDO DE REFERENCIA. MEDIANTE EL USO DE UN DISPOSITIVO DE FILTRO DE ACUERDO CON LA PRESENTE INVENCION NO HAY NECESIDAD DE INTERRUMPIR UN PROCESO DE FILTRADO PARA LIMPIAR EL FILTRO, YA QUE LA ACUMULACION COMPACTA DE RESIDUO FORMADA DURANTE EL PROCESO DE FILTRADO BAJO LA PRESION DEL FLUJO DE LIQUIDO SUMINISTRADO ES EXPULSADA EN SU TOTALIDAD ABRIENDO LA SEGUNDA DESCARGA APTA DE CIERRE, DE MODO QUE EL PROCESO DE FILTRADO SE PUEDE REANUDAR INMEDIATAMENTE.
