Brief Patent Description - Full Patent Description - Patent Application Claims
TECHNICAL FIELD [0001] This disclosure relates to systems and methods for separating hydrophobic fluids (such as oils) which are entrained as aerosols, from gas streams (for example, air streams). Preferred arrangements also provide for filtration of other fine contaminants, for example carbon material, from the gas streams. Methods for conducting the separations are also provided. BACKGROUND [0002] Certain gas streams, such as blow-by gases from the crankcase of diesel engines, carry substantial amounts of entrained oils therein, as aerosol. The majority of the oil droplets within the aerosol are generally within the size of 0.1-5.0 microns. [0003] In addition, such gas streams also carry substantial amounts of fine contaminant, such as carbon contaminants. Such contaminants generally have an average particle size of about 0.5-3.0 microns. [0004] In some systems, it is desirable to vent such gases to the atmosphere. In general, it is preferred that before the gases are vented to the atmosphere, they be cleaned of a substantial portion of the aerosol and/or organic particulate contaminants therein. [0005] In other instances, it is desirable to direct the air or gas stream into equipment. When such is the case, it may be desirable to separate aerosol and/or particulates from the stream during the circulation, in order to provide such benefits as: reduced negative effects on the downstream equipment; improved efficiency; recapture of otherwise lost oils; and/or to address environmental concerns. [0006] A variety of efforts have been directed to the above types of concerns. The variables toward which improvements are desired generally concern the following: (a) size/efficiency concerns; that is, a desire for good efficiency of separation while at the same time avoidance of a requirement for a large separator system; (b) cost/efficiency; that is, a desire for good or high efficiency without the requirement of substantially expensive systems; (c) versatility; that is, development of systems that can be adapted for a wide variety of applications and uses, without significant re-engineering; and, (d) cleanability/regeneratability; that is, development of systems which can be readily cleaned (or regenerated) if such becomes desired, after prolonged use. SUMMARY OF THE DISCLOSURE [0007] A filter arrangement is provided that includes a first stage coalescer filter and a second stage filter element downstream from the coalescer filter. Preferably, the first stage coalescer filter comprises a non-woven fibrous media. The second stage filter element will preferably include pleated media. Preferred constructions will include a filter arrangement including a tubular extension of pleated media defining an open filter interior, a first end cap at one end of the tubular extension of pleated media; the first end cap having an aperture in communication with the open filter interior; a second end cap at an end of the tubular extension of media opposite of the first end cap; and the fibrous media oriented in flow communication with the open filter interior. [0008] In preferred embodiments, a flow construction arrangement is oriented within the open filter interior oriented to direct fluid from the region of pleated media. [0009] Preferably, a preformed insert comprising a frame construction holds the fibrous media, and is secured to the first end cap. [0010] A gas cleaner is described that includes a housing construction with filter arrangements, constructed according to principles herein, operably installed and removably replaceable within the housing construction. [0011] In preferred applications, filter arrangements as described herein are usable to clean blowby gases from the crankcase of an engine. Systems, methods of use, and servicing are described herein.
