Effluent filtering device for use at outlet of e.g. oil well, has sweeping unit sweeping filtering residues residing on tubular effluent filtering member toward recuperation unit of residues

摘要

The device (50) has a tubular effluent filtering member (102) arranged between a tubular inlet member (64) and outlet member formed of a central pipe and tubular support (88). Sweeping unit (108) of the filtering member sweeps the filtering residues residing on the filtering member toward a recuperation unit (136) of the residues. The filtering member has an outer wall swept by the sweeping unit. The sweeping unit has a helical blade (110) extending coaxially to the filtering member and the tubular support comprises an internal surface arranged opposite to outer wall. An independent claim is also included for a method for filtering hydrocarbon.
