Patent ID: 8016121

Claim:
In combination with a duct in which droplet-laden air is flowing in a horizontal flow direction, a droplet separator comprising: a frame having a bottom plate, a top plate, and a pair of side plates bridging the top and bottom plates, the frame aligned in the direction with the duct and receiving the air flow therefrom, the bottom plate forming an upwardly open trough below a lower wall of the flow duct; a plurality of droplet-separator profiles extending vertically in the frame above the trough and defining horizontally throughgoing passages generally aligned with the flow direction, whereby droplets are separated from the air flow by impingement on the profiles and flow down into the trough; and a flow-restricting rib extending horizontally, vertically, and transversely of the flow direction below and between the profiles across the passages in the trough so as to subdivide a lower region of the trough into separate upstream and downstream compartments.
