Duct with contaminant separating barrier

摘要

A conduit carrying gaseous matter has a device inside it forming a low-lying sump for separating and collecting non-gaseous matter. The device fits within a flexible section of the conduit and includes a barrier plate oriented generally horizontally to longitudinally divide a length of the conduit into a gas-carrying passageway (above the barrier plate and a sump (below the barrier plate, a spacer extending from a lower surface of the barrier plate, and first and second frame members extending from an upper surface of the barrier plate at spaced-apart locations. The spacer and the frame member contact inner surfaces of the conduit to positively position the barrier plate within the conduit, and the frame members are oriented obliquely to one another to urge the flexible section of the conduit into a bent shape having a lowest portion defining the sump.

1. Apparatus comprising:
a conduit; an approximately oval plate within a curved section of the conduit, perimeter edges thereof immediately adjacent inner conduit surfaces to divide flow therethrough into two streams paralleling opposite plate surfaces; a spacer extending below a lower surface of the plate; and first and second rings extending from the plate, contacting upper inner conduit surfaces at longitudinally-spaced locations and oriented obliquely to one another to position the plate in the curved section.
