Abstract

UN FILTRO SEPTO ES CONSTRUIDO CON ELEMENTOS DE MICROPROTECCION DE LAMINAS DE ACERO INOXIDABLE QUE TIENEN APERTURAS UNIFORMEMENTE DISTRIBUIDAS A TRAVES DEL CUAL UN LIQUIDO A SER FILTRADO ES PASADO DESDE UN LATERAL DE ENTRADA A UNA LATERAL DE SALIDA DEL ELEMENTO. LAS APERTURAS ESTAN PREFERIBLEMENTE ESTRECHADAS DESDE UN DIAMETRO MAS GRANDE EN UN LATERAL DE ENTRADA A UN DIAMETRO MAS PEQUEÑO EN EL LATERAL DE SALIDA DEL ELEMENTO DE MICROPROTECCION. UNA LAMINA BASE DE METAL SOPORTE QUE TIENE FILAS DE AGUJEROS UNIFORMEMENTE DISTRIBUIDOS QUE SON MAS GRANDES ENTONCES LAS APERTURAS SOLDADA AL ELEMENTO DE MICROPROTECCION QUE UNE EL LATERAL DE SALIDA DEL ELEMENTO DE MICROPROTECCION AL LATERAL DE ENTRADA DE LA LAMINA BASE. PREFERIBLEMENTE EL LATERAL DE ENTRADA DEL ELEMENTO DE MICROPROTECCION ESTA CUBIERTO DE TEFLON.
