Abstract
Abstract A water cooling tower is shown which comprises a blower opening into the bottom of the tower for introducing or blowing air into the tower. A continuously walled wet decking arranged in a spiral mounted above the air inlet port and having a large number of regularly spaced projections arranged in an inclined checkerboard or step like pattern to control the counterflowing air and water in the tower. A spray tree for introducing water into the vessel is mounted above the wet decking and a mist eliminator mounted above the spray tree. The mist eliminator is also constructed in the form of a continuously spirally wound vertical wall with adjacent surfaces of the eliminator wall being separated by a multiplicity of step like baffles.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
A water cooling tower comprising: a vertically mounted, cylindrically shaped vessel having at least one port in a sidewall thereof located a spaced distance above the bottom thereof; air supply means communicatingly connected to said vessel port for introducing air into said vessel; water supply means mounted in an upper portion of said vessel for distributing water into said vessel; a continuous spiral, vertical wall with the adjacent surfaces thereof spaced from each other, mounted in said vessel above said port and below said water supply means for causing the water and air to follow a counterflow path; the continuous vertical wall comprising a multiplicity of projections arranged in a checkerboard pattern on said wall, said projections extending substantially the spaced distance between adjacent surfaces of said continuous spiral, vertical wall whereby fluids are caused to flow in a helical path; and conduit means connected to said vessel at the bottom thereof for withdrawing cooled water from the vessel.
Claim 2
Dependent Claim
