Abstract:
1. A filter apparatus for removing particulate material from a gas/fluid stream, said apparatus comprising: at least one tapered structure configured to filter particulate material from the gas/fluid stream, the at least one tapered structure having an apex forming a closed portion that is exposed to the gas/fluid stream and an open base portion, the gas/fluid stream moving in a direction from the apex toward the closed portion, wherein a first portion of the gas/fluid stream (i) traverses the at least one tapered structure, is drawn through an external surface of the at least one tapered structure into an interior of the at least one tapered structure, and emerges from the open base portion as filtered gas/fluid, a second portion of the gas/fluid stream with the particulate material flows along the external surface of the tapered structure from the apex toward the closed portion without being drawn into the interior, and after the first portion of the gas/fluid stream emerges from the open base portion of the at least one tapered structure as filtered gas/fluid, the first portion recombines with the second portion of the gas/fluid stream.
