Abstract

SE PRESENTA UNA LAMINA FILTRADORA DE EFICIENCIA MEJORADA (10) PARA FILTRAR PULPA EN UN APARATO DE FILTRADO A PRESION (8) EN LA QUE SE ESTABLECEN VARIOS PARAMETROS DE DISEÑO LOS CUALES INCREMENTAN EL RENDIMIENTO DEL FILTRADO, PARTICULARMENTE FILTRANDO PULPA DE CONSISTENCIA MEDIA. EL RECIPIENTE SE FORMA CON UN MATERIAL FINO SIMILAR A UNA HOJA FORMADO SIN UTILIZACION DE MEDIOS MECANICOS EN FORMA ONDULANTE. LAS FRECUENCIAS DE ONDULACION, LA SITUACION DE LA RANURA, LA FRECUENCIA DE BARRA DE TURBULENCIA Y LA ALTURA DE LA BARRA DE TURBULENCIA SE ESTABLECEN PARA INCREMENTAR EL RENDIMIENTO DEL FILTRO.
