CERAMICS HONEYCOMB FILTER AND METHOD OF MANUFACTURING THE SAME

摘要

A ceramics honeycomb filter (1), comprising a plurality of membrane filtration cells (4) separated from each other through a porous ceramics partition wall (2), having filtration membranes (3) disposed therein, and forming flow passages for filtrated fluid, a plurality of water collecting cells (5) separated from each other through the partition wall (2), positioned adjacent to the specified membrane filtration cells (4) through the partition wall (2), and forming the flow passages for the filtrated fluid produced by filtrating the fluid to be filtrated by the filtration membranes (3), an outer wall (6) surrounding the membrane filtration cells (4) and the water collecting cells (5), water collecting slits (7) passed from one portions of the outer wall (6) to the other portions of the outer wall (6) through the water collecting cells (5) at the positions of the outer wall (6) apart specified distances from both end parts of the water collecting cells (5) for flowing out the filtrated fluid passed through the water collecting cells (5) to the outside, and porous sealing member (8) filled in spaces ranging from the end faces of the water collecting cells to the water collecting slits (7). The ceramics honeycomb filter can supply the filtrated fluid with high cleanliness by effectively preventing the fluid to be filtrated and the filtrated fluid from accumulating therein.
