Title: Coaxial screen filter

Abstract

Methods and apparatus for removing a pollutant such as dust (33) from a fluid stream (34). A nested array of fibers (35) is provided in a substantially annular container (36) having openings in its inner (32) and outer (31) cylindrical sides of such size as to retain the fibers (35) within the container while permitting fluid (34) to pass through easily, and the pollutant-containing fluid stream (34) is passed through at least a substantial portion of the container (36) from a region (37) outside the outer side (31) to a region (38) inside the inner side (32). Thus a substantial fraction of the pollutant (33) is separated from the fluid stream (34) in a portion of the nested array (35) generally nearer to the outer side (31) of the container (36) than to the inner side (31). From time to time the container (36) is rotated about its axis to remove a substantial fraction of the separated pollutant (33) from the nested array (35), by tumbling action and by the force of gravity, through the openings in the outer side (31) of the container (36). To assist in this removal, purging fluid (41) may be directed back through the containermore » (36) from the inner side (32) during the tumbling.« less
