TANGENTIAL FILTER WITH A SUPPORTING ELEMENT INCLUDING A SET OF CHANNELS

摘要

The invention relates to a tangential filter for filtering a fluid such as a liquid, including or consisting of a supporting element in which, along a transverse plane P perpendicular to the central axis of said tubular supporting element: a) said supporting element only includes, in the central portion thereof, inner channels Ci which do not share a wall in common with the outer surface thereof, said inner channels having a substantially equivalent hydraulic diameter; b) said supporting element also includes peripheral channels Cp, including at least two adjacent peripheral channels A and B, each one of said two channels A and B sharing a wall in common (6, 7) with said outer surface (2); c) the ratio Dh between: the hydraulic diameter DhA of the first channel A and the hydraulic diameter DhB of the second channel B is no lower than 1.1; d) the number of peripheral channels B is no lower than the number of peripheral channels A; and e) the channel B has a hydraulic diameter DhB substantially identical to the hydraulic diameter of the inner channels (Ci).
