Abstract

<B>MéTODO PARA PRODUZIR UMA TORTA DE FILTRO<D> A presente invenção se refere a um método para produzir uma torta de sólidos criada na filtragem realizada por um secador de sucção provido com uma superfície com finos poros de sucção de líquido, em cujo método é criado, de forma a produzir a dita torta de sólidos, uma diferença de pressão entre a superfície de filtro do meio de filtragem de finos poros e a superfície oposta à dita superfície de filtro. De acordo com a invenção, em conexão com a formação da torta de filtro, a diferença de pressão entre a superfície de filtragem do meio de finos poros de filtragem e s superfície oposta à dita superfície de filtragem é controlada de maneira a ajustar a velocidade de formação da torta, e o tanque de filtragem do secador de sucção da superfície de lama é vantajosamente mantido em um nível que permite o uso de ao menos um membro de limpeza da superfície de filtro, essencialmente através de todo o processo de formação da torta do filtro.
