Abstract

SISTEMA DE FILTRO QUE POSSUI UM ELEMENTO DE FILTRO PRIMÁRIO E UM SECUNDÁRIO, ELEMENTO DE FILTRO SECUNDÁRIO E MÉTODO. A presente invenção refere-se a: sistema de filtro (100) compreendendo alojamento (110), entrada e saída de fluido (102, 108) formadas em paredes do alojamento (112, 120), elementos de filtro primário e secundário (50, 10) acomodados no alojamento (110); elementos de filtro; e método. O elemento de filtro secundário (10) está disposto a jusante o elemento de filtro primário (50) em tubo vertical (150), rigidamente conectado a uma das paredes do alojamento (120), o lado interno do tubo vertical (150) estando em conexão fluida com a saída de fluido (108). O elemento de filtro secundário (10) compreende meio de filtragem (16) formando corpo (36) que possui pelo menos uma costura longitudinal (18) ao longo do eixo longitudinal (L), e o corpo de filtro (36) do elemento de filtro secundário (10) tem a primeira borda (13) em região (12) que é curvada em estado inicial desenrolado do meio de filtragem (16) e reto em estado enrolado final do meio de filtragem (16) formando o corpo de filtro (36) e a segunda borda (15) na região oposta (14) do corpo de filtro (36) com relação ao eixo longitudinal (L) que é reto em estado inicial desenrolado do meio de filtragem (16) e curvado em estado enrolado final do meio de filtragem (16) formando o corpo de filtro (36).
