Abstract
A porous coalescing filter element of conical configuration is diposed within a substantially cylindrical filter housing such tha the area between the element and the wall increases in the direction of the primary phase flow to keep the annular velocity substantially constant or decreasing in the direction of primary fluid flow. The element may be manufactured with a round end and tapered walls terminating to a pointed apex, but is more preferably manufactured and secured within the filter housing using flat end caps on both ends. The filter element may be vacuumed formed, or manufactured from media in a flat sheet form, which may be pleated if desired.
Claims21
A porous filter element of conical shape formed of randomly oriented glass fibers which flows from the inside to the outside and has an upper annular sealing surface and a lower annular sealing surface, the filter element further including:
- a) at least one layer of a suitable thin sheet material wrapped around said porous filter element, and being in intimate contact therewith, and
- b) an outer support structure of sufficient rigidity to radially support said porous filter element and said suitable thin sheet material and having an inside diameter slightly smaller than the outside diameter of the combination of the porous filter element and said outer layer of sheet material and completely surrounding said combination.
A filter including, in combination:
- a) an inner support structure of an conical configuration,
- b) an inner layer of suitable sheet material wrapped around said tubular support structure,
- c) a porous filter element formed of randomly orientated glass fibers and being of conical shape,
- d) at least one outer layer of a suitable thin sheet material wrapped about said porous filter element and being in intimate contact therewith,
- e) an outer support structure of conical configuration and being of sufficient rigidity to radially support said porous filter element and said suitable thin sheet material and having an inside diameter slightly smaller than the outside diameter of the combination of said inner tubular support structure, said inner layer of said suitable sheet material, said porous filter element, and said outer layer of suitable sheet material and completely surrounding said combination.
A multiple element coalescing filter assembly including, in combination:
- a) a filter housing having an inlet and an outlet,
- b) a tube sheet, having a plurality of openings interposed between said inlet and outlet,
- c) a plurality of risers sealingly connected to said openings and said tube sheet and having integral filter sealing surfaces at the upper ends thereof,
- d) a plurality of elongated conical filtering elements mounted to said risers,
- e) an end cap assembly applying pressure axially to said elongated conical filtering elements to seal said elements between said integral sealing surfaces provided on said risers and said end cap assemblies,
- f) a lower sump provided immediately above said tube sheet,
- g) an upper drain in fluid communication with said upper sump,
- h) a lower sump provided below the inlet of said filter housing, and
- i) a lower drain communicating with said lower sump.
A multiple element coalescing filter assembly including, in combination:
- a) a filter housing having an inlet and an outlet,
- b) a tube sheet, having a plurality of openings interposed between said inlet and outlet,
- c) a plurality of risers sealingly connected to said openings and said tube sheet and having integral filter sealing surfaces at the upper ends thereof,
- d) a plurality of elongated conical filtering elements mounted to said risers,
- e) an end cap assembly to seal said elements between said integral sealing surfaces provided on said risers and said end cap assemblies,
- f) a lower sump provided immediately above said tube sheet to collect coalesced liquids,
- g) a drain in fluid communication with said sump to drain collected liquids.
