Cooling tower water distribution system
A cooling tower is provided having a heat exchange section. A water collection basin located above the heat exchange section. The water collection basin has a plurality of openings that allow water to be distributed downwardly onto the heat exchange section. The water collection basin openings each have a diameter of from 0.2 inch to 0.6 inch.
1. A cooling tower comprising:
an indirect heat exchange section,
a water collection basin located above the indirect heat exchange section,
the water collection basin having a plurality of openings that allow water to be distributed downwardly onto the indirect heat exchange section,
the water collection basin openings being arranged in lateral rows,
the water collection basin openings each having a diameter of from 0.2 inch to 0.6 inch,
the spacing between adjacent water collection basin openings is from 2.0 to 6.0 inches,
the indirect heat exchange section includes a plurality of plate type heat exchangers,
each plate type heat exchanger having a centerline, a front side, and a rear side, the front and rear sides being on opposite sides of the centerline,
each lateral row of water collection basin openings being directly above a corresponding one of the plate type heat exchangers to allow water to be distributed downwardly onto the corresponding plate type heat exchanger,
wherein each lateral row of water collection basin openings includes a first plurality of openings overlapping the centerline of the corresponding plate type heat exchanger and longitudinally biased toward the front side of the corresponding plate type heat exchanger,
wherein each lateral row of water collection basin openings includes a second plurality of openings overlapping the centerline of the corresponding plate type heat exchanger and longitudinally biased toward the rear side of the corresponding plate type heat exchanger, and
wherein each lateral row includes an alternating arrangement of the first plurality of openings and the second plurality of openings to evenly distribute the water across the front side and the rear side of the corresponding plate type heat exchanger.
2. The cooling tower of claim 1 wherein
adjacent water collection basin openings in each lateral row are longitudinally offset from each other.
3. The cooling tower of claim 1 further comprising at least one fan operable to generate airflow across the plate type heat exchangers.
4. The cooling tower of claim 1 further comprising:
an inlet pipe; and
a pre-distribution box in the water collection basin configured to receive water from the inlet pipe, the pre-distribution box permitting water to flow into the water collection basin.
5. The cooling tower of claim 1 further comprising a sump configured to collect water from the front and rear sides of the plate type heat exchangers.
6. A cooling tower comprising:
an indirect heat exchange section,
a water collection basin located above the indirect heat exchange section,
the water collection basin having a plurality of openings that allow water to be distributed downwardly onto the indirect heat exchange section,
the water collection basin openings being arranged in lateral rows,
the indirect heat exchange section includes a plurality of plate type heat exchangers,
each plate type heat exchanger having a centerline, a front side, and a rear side, the front and rear sides being on opposite sides of the centerline,
each lateral row of water collection basin openings being directly above a corresponding one of the plate type heat exchangers to allow water to be distributed downwardly onto the corresponding plate type heat exchanger,
wherein each lateral row of water collection basin openings includes a first plurality of openings overlapping the centerline of the corresponding plate type heat exchanger and longitudinally biased toward the front side of the corresponding plate type heat exchanger,
wherein each lateral row of water collection basin openings includes a second plurality of openings overlapping the centerline of the corresponding plate type heat exchanger and longitudinally biased toward the rear side of the corresponding plate type heat exchanger, and
wherein each lateral row includes an alternating arrangement of the first plurality of openings and the second plurality of openings to evenly distribute the water across the front side and the rear side of the corresponding plate type heat exchanger.
7. The cooling tower of claim 6 wherein the adjacent water collection basin openings in each lateral row are longitudinally offset from each other.
8. The cooling tower of claim 6 further comprising at least one fan operable to generate airflow across the plate type heat exchangers.
9. The cooling tower of claim 6 further comprising:
an inlet pipe; and
a pre-distribution box in the water collection basin configured to receive water from the inlet pipe, the pre-distribution box permitting water to flow into the water collection basin.
10. The cooling tower of claim 6 further comprising a sump configured to collect water from the front and rear sides of the plate type heat exchangers.
