Abstract
Filtering capacity of a honeycomb filter having a plurality of cells formed by a matrix of thin, porous intersecting walls and used for removing solid particulates mixed in fluids is improved by providing a porous outer wall around the thin walls through which the fluid is also filtered. A particulate barrier is provided between the outer wall and a conduit carrying the contaminated fluid to and filtered fluid from the filter which allows the fluid to flow along and through a substantial portion of the porous outer surface of the filter while preventing contaminated fluid from bypassing the filter. The barrier is preferably formed near an inlet or an outlet end face of the filter and those cells which are located around the periphery of the end faces are preferably open at that same end face and closed at the remaining end face to assure fluid flow across the porous outer wall. A method of filtering solid particulates from a fluid comprises providing the filter, conducting a fluid contaminated with solid particulates into the filter, filtering the particulates from the fluid by means of the thin walls and also through a substantial portion of the outer wall, and conducting filtered fluid away.
