Filter element for fluid medium with retention of filtrate has support with outer surface and three or more channels with peripheral walls and partitions of variable thickness

摘要

#CMT# #/CMT# The filter element (1) consists of a support (12) e.g. of extruded ceramic material with an outer surface (14) and three or more channels (161 - 166). The channels have peripheral walls (18) adjacent to the outer surface of the support, shaped so that the distance between the wall and outer surface reduces from the centre of the channel to its outer edges. In addition the side walls (20) of the channels form partitions (22) of varying thickness between adjacent channels. Each partition has one portion of constant thickness and another in which the thickness increases from the centre of the support outwards. Variants of the design can have one or more rows of channels in concentric rings. #CMT#USE : #/CMT# Filtering fluids with retention of the filtrate. #CMT#ADVANTAGE : #/CMT# Increased contact area and greater resistance to operation in severe conditions. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-section of one version of the filter element. 1 : Filter element 12 : Support 14 : Outer surface 18 : Peripheral wall of channel 20 : Side wall 22 : Partition 161 - 166 : Channels.
