COOLING TOWER PLUME CONTROL

摘要

A cooling tower having a standard wet evaporative cooling tower combined with a dry heat exchanger system. The dry section includes a plurality of vertically spaced heat exchange tubes positioned directly above the packing area of the wet section. Water to be cooled flows through the tubes for preliminary cooling and then is directly distributed over the packing area of the wet section via nozzles associated with the lower ends of each tube. The heat exchange tubes are spaced a greater distance apart than ordinarily found in a typical heat exchanger to achieve maximum heat transfer and minimum pressure drop. The tubes are supported from their lower ends and fixed in place at their upper ends by a rubber grommet received through the water basin floor. A finned tubular insert is removably received through the upper end of each tube for control of the water flow. The air flow to both the wet and dry sections are controlled by mechanically adjustable louvers or dampers.
