Abstract
The present disclosure generally relates to the field of filtration. In particular, the present disclosure relates to filtration devices, systems and methods for high flowrates and low pressure differentials through porous bodies of metal fiber media.
Claims14
A filter comprising:
- a porous elongate body comprising metal fiber media, having a first end that is open, a second end that is closed, and a porous sidewall configured to filter fluids that flow through it;
- a duct extending from the first end to the second end;
- wherein the porous elongate body defines a flow path from the first end, into the duct, and across the porous sidewall;
- and
- wherein the porous elongate body comprises a rolled sheet of metal fiber media overlapping itself, a first seam weld extending lengthwise along the rolled sheet of metal fiber media at the overlap, and a second weld extending lengthwise along the porous elongate body, wherein the second weld is substantially offset about 180 degrees from the first seam weld about a longitudinal axis extending along the porous elongate body.
2 more elements
A filter system comprising:
- a plurality of porous elongate bodies each comprising metal fiber media, each having a first end that is open, a second end that is closed, a duct extending from the first end to the
- second end, and wherein the each porous elongate body defines a flow path from the first end, into the duct, and across a porous sidewall, and wherein each porous elongate body comprises a rolled sheet of metal fiber media forming the porous sidewall overlapping itself, a first seam weld extending lengthwise along the rolled sheet of metal fiber media at the overlap, and a second weld extending lengthwise along the porous elongate body, wherein the second weld is substantially offset about 180 degrees from the first seam weld about a longitudinal axis extending along the porous elongate body;
- and
- a housing having an inlet and an outlet, disposed about the plurality of porous elongate bodies;
- and
- wherein the plurality of porous elongate bodies are disposed within the housing in parallel such that each first end is oriented toward the inlet and each second end is oriented toward the outlet.
3 more elements
A method of manufacturing a filter comprising:
- rolling a first sheet into a first porous elongate body such that there is a portion of the sheet overlapping itself and wherein the portion is about an eighth of an inch in the circumferential direction of the rolled sheet;
- seam welding the portion of the first porous elongate body to provide a first seam weld;
- and
- welding along a length of the first porous elongate body along a longitudinal axis of the porous elongate body at a location substantially 180 degrees offset from the first seam weld, to form a second weld.
