Cooling tower design

Claim 2

A cooling tower for cooling liquid by counter-current flow through a rising flow of air comprising: an upright surrounding wall having an upper end, and defining a flue adapted to contain said counter-current flow of liquid and air; conduit means adapted to distribute said liquid to substantially the entire area of said flue and having outlet ports at spaced intervals adapted to disperse said liquid into said air flow; demister means disposed across the flue in the path of said air flow and adapted to remove vapour therefrom; support means adapted to support said liquid conduit means and said demister means in said tower and adapted to permit removal and replacement thereof as a unit; said support means including: horizontal beams spanning across said flue to rest on the upper end of said wall; a plurality of vertical members depending from said beams within said flue adjacent to said wall; a ring mounted on said vertical members and extending horizontally around said flue parallel to and in close proximity to said wall and having an inwardly projecting ledge; a platform formed of a lattic of intersecting beams resting at their outer ends on said ledge of said ring; said platform thus being adapted to support said demister means resting thereon and said liquid distribution means hanging therefrom.

Claim 3

A cooling tower as claimed in claim 1 in which said liquid distribution means includes an inlet pipe mounted to enter downwardly into said cooling tower and a plurality of horizontally extending pipes connected to said inlet pipe and radiating from the centre of said flue to substantially the entire area thereof, said radiating pipes having said outlet ports therein, and being suspended from said platform.

Claim 4

A cooling tower as claimed in claim 2 in which said platform has a grid of inverted T members mounted on top of and parallel to said platform beams respectively to form a number of compartments each adapted to receive therein a segment of said demister means.

Claim 5

A cooling tower as claimed in claim 3 in which said demister means, said liquid distribution means, and said support means are made of plastic materials.

Claim 6

A cooling tower for cooling liquid by counter-current flow through a rising flow of air comprising: an upright surrounding wall having an upper end, and defining a flue adapted to contain said counter-current flow of liquid and air; conduit means adapted to distribute said liquid to substantially the entire area of said flue and having outlet ports at spaced intervals adapted to disperse said liquid into said air flow; demister means disposed across the flue in the path of said air flow and adapted to remove vapour therefrom; support means adapted to support said liquid conduit means and said demister means in said tower and adapted to permit removal and replacement thereof as a unit; said support means including: horizontal beams spanning across said flue to rest on the upper end of said wall; a plurality of vertical members depending from said beams within said flue adjacent to said wall; a first ring and a second ring respectively mounted on said vertical members and extending horizontally around said flue parallel to and in close proximity to said wall and having an inwardly projecting ledge; a first platform and a second platform respectively formed of a lattice of intersecting beams resting at their outer ends on the ledge of said rings respectively; said first platform being spaced above said second platform and being thus adapted to support said demister means resting thereon and said liquid distribution means being suspended from said second lower platform.

Claim 7

A cooling tower for cooling liquid by counter-current flow through a rising flow of air comprising: an upright surrounding wall having an upper end, and defining a flue adapted to contain said counter-current flow of liquid and air; conduit means adapted to distribute said liquid to substantially the entire area of said flue and having outlet ports at spaced intervals adapted to disperse said liquid into said air flow; demister means disposed across the flue in the path of said air flow and adapted to remove vapour therefrom; support means adapted to support said liquid conduit means and said demister means in said tower and adapted to permit removal and replacement thereof as a unit; said support means including: horizontal beams spanning across said flue to rest on the upper end of said wall; a plurality of vertical members depending from said beams within said flue adjacent to said wall; a first ring and a second ring respectively mounted on said vertical members and extending horizontally around said flue parallel to and in close proximity to said wall and having an inwardly projecting ledge; a first platform and a second platform respectively formed of a lattice of intersecting beams resting at their outer ends on the ledge of said rings respectively; said first platform being spaced above said second platform and being thus adapted to support said demister means resting thereon and said liquid distribution means being suspended from said second lower platform.

Claim 8

A cooling tower as claimed in claim 5 in which said liquid distribution means includes an inlet pipe mounted to enter downwardly into said cooling tower and a plurality of horizontally extending pipes connected to said inlet pipe and radiating from the center of said flue to substantially the entire area thereof, said radiating pipes having said outlet ports therein and being suspended from said second platform.

Claim 9

A cooling tower as claimed in claim 6 in which said first upper platform has a grid of inverted T members mounted on top of and parallel to said platform beams respectively to form a number of compartments each adapted to receive therein a segment of said demister means.

Claim 10

A cooling tower as claimed in claim 7 in which said demister means, said liquid distribution means, and said support means are made of plastic materials.
