An apparatus for separating a contaminated liquid diesel fuel and the like into a substantially uncontaminated homogeneous raffinate fuel portion and into a heterogeneous extract portion. Upon being subjected to sufficient circular flow, in an environment emulating the action of a centrifuge, the heavier liquid and solid components are caused to gravitate out of the diesel fluid and the like. This apparatus is constructed with an elongated housing means which is preferably disposed between the fuel tank and fuel filter of a diesel engine and the like. Contained longitudinally within the elongated housing is a separator chamber having a portion of a frustoconically shaped centrifugation surface which directs the incoming impure and contaminated fuel mixture into a turbulent and circular pattern. As the fuel mixture gains momentum during this centrifuge-like flow pattern, it abruptly strikes a substantially vertical impact plate which precipitates the forced separation of the impurities and contaminants from the fuel. The heavier extract component gravitates to a sump region located in the bottom of the housing, while the lighter fuel raffinate component rises into a raffinate separation region located in the top of the housing. A combination of baffle plates both promote the separation of the extract from the fuel raffinate and prevent the re-mixing thereof, once separation occurs. The accumulated extract portion is discharged through a drain at the bottom of the housing and fuel raffinate is discharged to a downstream fuel filter through an outlet located in the top portion of the housing. |
