Abstract
Abstract A high performance water collector (1) dries a moisture-laden airstream within a duct (7) by providing an air guide (20) with a gap (12) between a collector inlet section (4) and discharge section (6). The guide (20) defines a scupper (26) to direct the heavily moisture-laden air to a diffuser (14) surrounding the gap (12). The diffuser (14) slows the air, causing the water to fall naturally within the diffuser (14) for subsequent removal. The guide (20) further defined an ejector (28) for infusing the dried air back into the duct.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
213 words
Apparatus, adapted for mounting in a duct having an upstream portion and a downstream portion, for drying a moisture-laden portion of an airstream flowing through said duct, said apparatus being adapted for use with centrifugal separation means for concentrating said moisture-laden portion along walls of said duct, said apparatus comprising: an inlet conduit portion attached to said upstream portion of said duct said airstream passing through said inlet conduit portion from said upstream portion, an outlet conduit portion attached to said downstream portion of said duct said airstream passing through said outlet conduit portion from said inlet conduit portion to said downstream portion, a diffuser chamber means for drying said moisture-laden portion, said diffuser means surrounding and attached to a portion of said inlet conduit portion and a portion of said outlet conduit portion said diffuser chamber means being in communication with said airstream, and guide means, extending into said diffuser chamber means and extending into said airstream, said guide means passing said moisture-laden portion from said airstream into said diffuser chamber means, said guide means guiding said moisture-laden portion along a reversing flow path within said diffuser chamber to remove moisture from said moisture-laden portion and said guide means passing a dried portion from said diffuser chamber means to said outlet portion.
Claim 2
Dependent Claim
213 words
Apparatus, adapted for mounting in a duct having an upstream portion and a downstream portion, for drying a moisture-laden portion of an airstream flowing through said duct, said apparatus being adapted for use with centrifugal separation means for concentrating said moisture-laden portion along walls of said duct, said apparatus comprising: an inlet conduit portion attached to said upstream portion of said duct said airstream passing through said inlet conduit portion from said upstream portion, an outlet conduit portion attached to said downstream portion of said duct said airstream passing through said outlet conduit portion from said inlet conduit portion to said downstream portion, a diffuser chamber means for drying said moisture-laden portion, said diffuser means surrounding and attached to a portion of said inlet conduit portion and a portion of said outlet conduit portion said diffuser chamber means being in communication with said airstream, and guide means, extending into said diffuser chamber means and extending into said airstream, said guide means passing said moisture-laden portion from said airstream into said diffuser chamber means, said guide means guiding said moisture-laden portion along a reversing flow path within said diffuser chamber to remove moisture from said moisture-laden portion and said guide means passing a dried portion from said diffuser chamber means to said outlet portion.
Claim 3
Dependent Claim
34 words
Apparatus of claim 1 wherein said guide means is characterized by a ring having a U-shaped cross section with a first leg extending into said airstream and a second leg extending into said diffuser.
Claim 4
Dependent Claim
30 words
Apparatus of claim 1 wherein said flow path increases in volume therealong whereby said velocity of said separated moisture-laden portion is reduced to remove moisture from said separated moisture-laden portion.
Claim 5
Dependent Claim
15 words
Apparatus of claim 3 wherein said flow path substantially reverses direction at least two times.
Claim 6
Dependent Claim
34 words
Apparatus of claim 3 wherein said guide means is characterized by a ring having a U-shaped cross section with a first leg extending into said airstream and a second leg extending into said diffuser.
Claim 7
Dependent Claim
15 words
Apparatus of claim 5 wherein said inlet portion diverges radially outwardly towards said outlet portion.
Claim 8
Dependent Claim
29 words
Apparatus of claim 5 wherein said guide means is further characterized by a duct disposed within said inlet portion and said outlet portion and attached to said first leg.
Claim 9
Dependent Claim
15 words
Apparatus of claim 7 wherein said second duct tapers radially inwardly toward said outlet portion.
