ABSTRACT:
A phase separator or vapor trap is provided for use with a plastic extruder. The phase separator includes housing means which define a first chamber for separating hydrocarbon compounds from exhaust vapor, an internal conduit located within the first chamber, and a couple which joins extruder discharge conduit with the inlet of the internal conduit. The inlet means provides a larger cross-sectional area than the extruder vapor exhaust conduit. The first chamber includes a baffle which surrounds the internal conduit and further defines at least one flow opening. The aggregate cross-sectional area of the flow openings are substantially the same as the cross-sectional area of the discharge conduit. Diffusion means adjustably attached to the end of the internal conduit causes radial diffusion of the exhaust vapor within the first chamber. The housing also includes a removable collection receptacle to collect residue which condensates out of the exhaust vapor and camming catches to seal the collection receptacle with the rest of the housing. A single worker can simultaneously support the collection receptacle and form the seal between the collection receptacle and the rest of the housing.
