CONTAMINANT SEPARATOR FOR A NITROGEN GENERATION SYSTEM AND METHOD OF REMOVING CONTAMINANTS FROM AN AIRSTREAM

摘要

A contaminant separator (10) for a nitrogen generation system includes a swirl vane chamber (16) defined by a chamber wall (22) and configured to receive an air bleed flow (12). A vane (24) is located within the swirl vane chamber (16) and is configured to direct contaminants heavier than air radially outwardly toward the chamber wall (22). An ejector (26) is defined by an ejector wall (28) and is located downstream of the swirl vane chamber (16) and radially inwardly of the chamber wall (22). A housing (38) surrounds the ejector (26) and the chamber wall (22). A contaminant separating path (34) extends from an inlet comprising an annular gap (32) defined by the chamber wall (22) and the ejector wall (28) to an outlet (50) defined by the housing (38) and the ejector wall (28).
