ABSTRACT:
A filtration apparatus is described wherein entrained solids are removed from particulate-carrying fluid by filtration under vigorous conditions with filter tubes. The filter apparatus comprises a plurality of tiers of filters, each tier comprising filter tubes supported on a tube sheet. The apparatus also contains a tiered conical sluicing system to concentrate and centralize the particulates. The solids discharge from the filter tubes and pass through the sluicing system to exit the apparatus through particulate outlet means. The use of the apparatus is characterized by a reduced re-entrainment of particulates in the fluid leaving the apparatus.
