Abstract

"DESENVOLVIMENTO EM CARTUCHO DE FILTRO DE COMPOSTO APERFEIçOADO". A ser protocolado como pedido de Certificado de Adição de Invenção do PI0011213-5, caracterizado por compreender: A) um envoltório cilíndrico de material de carbono (44) tendo radialmente uma superfície externa, uma cavidade central (56) formando radialmente uma superfície interna, uma superfície de extremidade superior (52a) e uma superfície de extremidade inferior; B) um feixe de fibras microporosas ocas (48) alojadas dentro da cavidade central (56) do envoltório de carbono (44); C) uma saída de fluido provido da superfície de extremidade superior (52a) do envoltório de carbono (44) e comunicando-se com as fibras microporosas ocas (48), de modo que o fluido entre no cartucho de filtro (50) através da superfície exterior do envoltório de carbono (44), flui de modo radial internamente para cavidade central (56) do envoltório de carbono (44), então axialmente através das fibras microporosas ocas (48), e sai do cartucho de filtro (50) através da saída de fluido provida na superfície de extremidade superior (52a) do envoltório de carbono (44); e D) um pré-filtro (44a) cobrindo radialmente a superfície externa do envoltório de carbono (44), e por meio dele passa o fluido através do pré-filtro antes de entrar no cartucho de filtro (50) através da superfície externa do envoltório de carbono (44).
