Title:
CERAMIC HONEYCOMB FILTER AND PRODUCTION METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3868391
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To effectively prevent retention of fluid to be filtered and a filtrate inside a filter, and to supply the highly cleaned filtrate.
SOLUTION: The subject ceramic honeycomb filter 1 is provided with a plurality of membrane filter cells 4 sectioned by porous ceramic partitions 2 with filter membranes 3 disposed therein, serving as flow passages of the fluid to be filtered; a plurality of water collection cells 5 sectioned by the partitions 2, adjacent to prescribed membrane filter cells 4 across the partitions 2 and serving as flow passages of the filtrate obtained by filtering the fluid to be filtered by the filter membranes 3; an outer wall 6 surrounding the filter cells 4 and water collection cells 5; water collection slits 7 allowing flowing out of the filtrate passing through the water collection cells 5, penetrating through the water collection cells 5 from one part of the wall 6 at a part distant from both ends of the collection cells 5 of the wall 6 by a prescribed length, and communicated with the other part of the wall 6; and porous filling materials 8 filled in spaces between the end faces of the water collection cells 5 and the water collection slits 7.
