Abstract

SE DISPONE DE UN ELEMENTO DEL FILTRO, ADAPTADO PARA EL USO EN ALOJAMIENTOS DE FILTRO DE ALTA PRESION, QUE TIENE UNA DIVERSIDAD DE CAPAS DE MATERIAL DE FILTRO FLEXIBLE ALGUNA DE LAS CUALES ESTAN FORRMADAS POR ABERTURAS TRANSVERSALES POR LAS QUE PUEDE FLUIR UNA PARTE DEL FLUIDO SIN SER FILTRADO Y COMO MINIMO UNA CAPA DE CORRIENTE DE BAJA DE MATERIAL DE FILTRO QUE ESTA LIBRE PARA CADA ABERTURA. CUANDO TODAS LAS CAPAS TIENEN EL MISMO TAMAÑO DE PORO, EL AREA TOTAL DE LAS ABERTURAS EN CADA CAPA ES MAS LARGA QUE LAS ABERTURAS DE LA CAPA DE LA CORRIENTE DE BAJA. CADA CAPA DE ABERTURA DE CONTENCION DE MATERIAL FILTRANTE REMUEVE PARTE DE LO CONTAMINADO EN EL FLUIDO INTERPUESTO ENTRE LAS CAPAS DE FILTRO DE ABERTURA DE CONTENCION ADYACENTES ESTA UNA CAPA DE MATERIAL DE TRANSPORTE FLEXIBLE, Y UNA CAPA DE MATERIAL DE PREFILTRACION FLEXIBLE POSICIONADA EN LA CORRIENTE SUPERIOR DE DICHAS CAPAS DE FILTRO. EL MATERIAL DE PREFILTRACION TIENE UNA POROSIDAD PARA FILTRAR AL EXTERIOR DEL FLUIDO ALGUNA PARTICULA SUSTANCIALMENTE MAS GRANDE QUE LAS MAYORES DE LAS CAPAS DE FILTRO DE LA CORRIENTE DE ALTA PARA RESGUARDAR CONTRA UNA APERTURA QUE PUEDE LLEGAR A SER BLOQUEADA POR TAL PARTICULA.
