<p>The invention relates to a filter (10) for a feeding system for liquids with tendency to form sediments, in particular for a crude oil washing system, the filter (10) being adapted to be inserted into a filter casing (11) provided in a feed line of the feeding system and allowing only the passage of the liquid comprising particles of small diameter, the filter (10) having a hollow filter body (16) with side walls (17) and a bottom portion (18), an inlet (14) being in fluid communication with the feed line (12), pores (20) provided in at least a portion of the side walls (17) allowing the passage of the liquid from the inside of the filter body (16) into the surrounding filter casing (11), and is characterized by a rotor (30) located at the bottom portion /18) of the filter body (16) arranged for rotation at high speed, and a sieve plate (31) located above the rotor (30) and extending over a portion of the filter body (16) diameter, the position of the plate (31) and its distance to the rotor (30) being chosen such, that the liquid directed upwards by the rotating rotor (30) is pressed under high speed against the sieve plate (31).</p> |
