Claim:
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.
