Abstract

"MéTODO DE FILTRAçãO". A presente invenção se refere a um método de filtração onde o material a ser filtrado é trazido em contato com uma superfície de filtração de um meio de filtração disposto em um secador de sucção, e em cima da superfície de filtração do meio de filtração é formada uma torta de filtro, e a torta de filtro é submetida para um processo de secagem constituindo pelo menos uma etapa de processo precedente à remoção da torta de filtro a partir da superfície de filtração do meio de filtração. Em concordância com a presente invenção, no processo de secagem de torta de filtro, é executada pelo menos uma etapa de secagem (12, 22, 32, 42) durante a qual gás é prevenido a partir de fluência através do meio de filtração, e pelo menos uma etapa de secagem (13, 23, 33, 44) durante a qual gás flui através do meio de filtração.
