Abstract
The invention provides for easy, efficient repair and maintenance of cooling towers by a design in which the internal elements such as liquid distribution pipes, demister, grating and the like are structurally unified with a supporting means so that they can be removed from or replaced in the tower as a unit.
Claims8
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.

- 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.
