Abstract
An apparatus is disclosed for maintaining constant fluid pressure and equalized fluid flow among a plurality of downcomer lines through which liquid from a tower is directed. A substantially annular fluid distribution belt is disposed at the circumference of the tower. The fluid distribution belt collects liquid from the tower. At least two outlets direct liquid from the fluid distribution belt out of the tower and into a corresponding number of downcomer lines disposed external to the tower.
Claims18
An apparatus for maintaining constant fluid pressure and equalized fluid flow among a plurality of downcomer lines through which liquid from a substantially cylindrical tower is directed, comprising:
- a substantially annular fluid distribution belt positioned about a circumference of the tower, the fluid distribution belt collecting liquid from the tower;
- at least two outlets configured to direct liquid from the fluid distribution belt into a corresponding number of downcomer lines disposed external to the tower;
- and
- a textured surface on a top end of each of the downcomer lines.

- at least two outlets configured to direct liquid from the fluid distribution belt into a corresponding number of downcomer lines disposed external to the tower;
- and
- at least one opening in each downcomer line at an elevation that is below a top end of said each downcomer line and within the fluid distribution belt, whereby liquid collected in the tower begins to flow through the at least one opening before reaching said top end of said each downcomer line.
