Abstract

Abstract A cooling tower with a film fill assembly having an inclined principal plane adjacent a gas inlet at the same general elevation. The assembly comprises a number of sheets (preferably of the corrugated type) with ample spacing there-between for the passage of gas and liquid. Multiple spaced-apart assemblies may be utilized for various tower applications. Also, splash-type fill may be disposed to the interior or exterior of the film fill assembly for increased gas-liquid contact.

Claim 3
Dependent Claim 29 words
A tower as in claim 1 in which said splash-type fill is disposed in an area of said tower between said film fill means and said gas outlet opening.
Claim 4
Dependent Claim 26 words
A tower as in claim 2 in which a substantial portion of said gas outlet opening is of the same elevation as said gas inlet opening.
Claim 5
Dependent Claim 21 words
A tower as in claim 3 in which said splash-type fill is of a crossflow type with generally horizontal splash decks.
Claim 6
Dependent Claim 21 words
A tower as in claim 2 in which said gas outlet opening is disposed in the upper portion of the tower.
Claim 7
Dependent Claim 16 words
A tower as in claim 5 in which said splash-type fill comprises generally upright splash decks.
Claim 8
Dependent Claim 28 words
A tower as in claim 1 in which said splash-type fill is disposed in an area of said tower between said side wall and said film fill means.
Claim 9
Dependent Claim 31 words
A tower as in claim 1 in which said sheets are disposed so that the gas path into and out of the film fill assembly is generally parallel to said sheets.
Claim 10
Dependent Claim 26 words
A tower as in claim 1 in which the sheets of said film fill means are disposed to provide different paths for gas and gravitating liquid.
Claim 11
Dependent Claim 27 words
A tower as in claim 1 in which the film fill means is disposed to provide paths of substantially different lengths for gas and for gravitating liquid.
Claim 12
Dependent Claim 23 words
A tower as in claim 1 in which the splash fill means is at essentially the same elevation as the film fill means.
