Water distribution method and flume for water cooling tower

摘要

A mechanical draft crossflow cooling tower is provided with a novel hot water distribution structure which overlies a fill assembly. The distribution structure includes a basin which extends horizontally along the length of the fill assembly and the basin bottom is provided with a plurality of metering nozzles for directing the flow evenly across the top face of the fill assembly. Additionally, a flume is located within the confines of the basin and extends horizontally along the length of the latter in spaced disposition from the basin bottom. The flume has opposed sidewalls which are operable as weirs such that the water is evenly directed to all areas of the basin. As such, the static head on each of the nozzles is equivalent throughout the length of the basin so that the hot water is evenly directed toward all areas of the fill assembly regardless of the flow rate of the water.
