Anti-clogging filter system
View Patent ↗An anti-clogging filter system for filtering a fluid containing large particles and small particles includes an enclosure with at least one individual elongated tubular filter element in the enclosure. The individual elongated tubular filter element has an internal passage, a closed end, an open end, and a filtering material in or on the individual elongated tubular filter element. The fluid travels through the open end of the elongated tubular element and through the internal passage and through the filtering material. An anti-clogging element is positioned on or adjacent the individual elongated tubular filter element and provides a fluid curtain that preferentially directs the larger particulates to one area of the filter material allowing the remainder of the filter material to remain more efficient.
1. An anti-clogging filter apparatus for filtering a fluid containing large particles and small particles, comprising:
an enclosure having an enclosure surface;
a multiplicity of individual elongated tubular filter elements in said enclosure with each of said individual elongated tubular filter elements having
an internal passage,
a closed end,
an open end; and
a filtering material in or on said individual elongated tubular filter elements,
wherein said elongated tubular filter elements are mounted on said enclosure surface so that the fluid travels from said enclosure through said filtering material and through said open end and out of said enclosure, wherein said filtering material has different areas; and
an anti-clogging element on each of said individual elongated tubular filter elements,
wherein said individual elongated tubular filter elements are arranged in rows in said enclosure and
wherein said anti-clogging element on said individual elongated tubular filter elements comprises
a multiplicity of fluid diverters positioned on said individual elongated tubular filter elements that close said internal passage of said individual elongated tubular elements and provide said closed end of said individual elongated tubular elements,
each of said fluid diverter elements including a multiplicity of individual tubulator vanes positioned outside of said internal passage and outside of said individual elongated tubular elements with said individual tubulator vanes extending from said closed end of said individual elongated tubular elements,
wherein said tubulator vanes create fluid curtains that cause the fluid to swirl around said individual elongated tubular elements and that direct the large particulates and the small particulates to said different areas of said filtering material as said fluid curtain swirls around said elongated tubular filter elements.
2. The anti-clogging filter apparatus for filtering a fluid containing large particles and small particles of claim 1 wherein said fluid diverters include a ring and wherein said tabulator vanes extend from said ring.
3. An anti-clogging filter apparatus for filtering a fluid containing large particles and small particles, comprising:
an enclosure having an enclosure surface;
an individual elongated tubular filter element in said enclosure with said individual elongated tubular filter element having
an internal passage,
a closed end,
an open end; and
a filtering material in or on said individual elongated tubular filter element, wherein said elongated tubular filter element is mounted on said enclosure surface so that the fluid travels from said enclosure through said filtering material into and through said internal passage and through said open end and out of said enclosure, wherein said filtering material has different areas; and
an anti-clogging element on or adjacent said individual elongated tubular filter element,
wherein said anti-clogging element on or adjacent said individual elongated tubular filter elements comprises a fluid diverter positioned over said open end of said individual elongated tubular filter element that closes said internal passage of said individual elongated tubular element and provides said closed end of said individual elongated tubular element and wherein said fluid diverter includes tubulator vanes positioned outside of said closed end of said individual elongated tubular element, wherein said tubulator vanes create a fluid curtain that preferentially directs the large particulates and the small particulates to said different areas of said filtering material and wherein said fluid curtain comprises swirls that travel around said elongated tubular filter elements.
4. The anti-clogging filter apparatus for filtering a fluid containing large particles and small particles of claim 3 wherein said fluid curtain comprises swirls that travel around said elongated tubular filter elements in the same direction.
5. The anti-clogging filter apparatus for filtering a fluid containing large particles and small particles of claim 3 further comprising a second fluid diverter positioned outside of individual elongated tubular filter element wherein said fluid diverter and said second fluid diverter create at least two fluid curtains that comprise swirls and wherein said swirls travel around said elongated tubular filter element in the same direction.
6. A method of filtering a fluid containing large particles and small particles, comprising the steps of:
providing an enclosure with an enclosure surface;
providing an elongated tubular filter element in said enclosure, said individual elongated tubular filter element having an internal passage, a closed end, an open end, and a filtering material in or on said individual elongated tubular filter element wherein said filtering material has different areas;
providing an anti-clogging element on said at least one elongated tubular filter element located over said open end of said individual elongated tubular filter element that closes said internal passage of said individual elongated tubular element and provides said closed end of said individual elongated tubular element; and
directing the fluid into said enclosure to said anti-clogging element and said individual elongated tubular filter element through said filtering material and through said internal passage of said individual elongated tubular filter element and out of said enclosure through said open end of said individual elongated tubular filter element,
wherein said step of providing an anti-clogging element comprises providing a fluid diverter positioned over said open end of said individual elongated tubular filter element that closes said internal passage of said individual elongated tubular element and provides said closed end of said individual elongated tubular element, wherein said anti-clogging element creates an fluid curtain that preferentially directs the large particulates and the small particulates to said different areas of said filtering material.
7. The anti-clogging filter method of filtering a fluid containing large particles and small particles of claim 6 wherein said step of providing an anti-clogging element comprises the step of providing an anti-clogging element having tubular element vanes extend from a ring.
