Abstract
A direct forced draft counterflow water cooling tower module includes an integral one-piece frame and basin preferably constructed from molded fiberglass. The cooling tower includes a liquid distribution system, fill material located below the liquid distribution system, a drainage collection system located below the fill material, and at least one fan located below the drainage collection system. The fan blows cooling air directly upward through the drainage collection system and then through the fill material.
Claims19
A transportable cooling tower module, comprising:
- a basin;
- four walls extending vertically upward from said basin;
- an air supply duct having an air intake opening defined in a bottom thereof and an air discharge outlet defined in a top thereof, said air supply duct extending vertically through said basin so that said basin laterally surrounds said air supply duct;
- a vertical axis fan located in said air supply duct;
- a drainage collection system located above said basin and said air supply duct, said drainage collection system including a plurality of parallel elongated collection plates having a length, said collection plates being sloped and overlapping in a direction transverse to said length of said collection plates, each collection plate having a lower gutter portion arranged to drain into said basin, said overlapping collection plates covering said fan;
- a body of fill material located directly above said drainage collection system, said body of fill material having a vertical thickness of at least approximately four feet;
- a liquid distribution system including at least one horizontal pipe supported from opposed ones of said side walls and including at least one nozzle spaced above said body of fill material so as to have a free fall height of spray from said nozzle to said fill material of less than one foot;
- a drift eliminator located above said horizontal pipe of said liquid distribution system;
- and
- said transportable cooling tower module having an overall height from a bottom of said basin to a top of said walls of less than eleven feet.
7 more elements
A cooling tower, comprising:
- at least one layer of fill material;
- a liquid distribution system for distributing liquid onto said fill material;
- a drainage collection system located under said fill material;
- at least one fan located under said drainage collection system to force air directly upward from said fan through said drainage collection system and through said fill material;
- a frame supporting said liquid distribution system, said fill material, said drainage collection system and said fan;
- a basin supported by said frame and located below said drainage collection system to receive liquid run-off from said drainage collection system;
- an air supply duct having an air intake opening defined in a bottom of said tower and having an air discharge opening directed upward toward said drainage collection system;
- said fan being located within said air supply duct;
- said basin laterally surrounding said air supply duct;
- wherein said drainage collection system has an underside against which air is directly blown by said fan;
- wherein said air supply duct include a secondary liquid collection means for directing condensate and spray collecting on said underside of said drainage collection system into said basin;
- and
- wherein said air supply duct includes a lower cylindrical duct portion telescopingly received within an upper cylindrical duct portion with an annular gap between overlapping portions of said lower and upper cylindrical duct portions, said annular gap being communicated with said basin and being part of said secondary liquid collection means.
