ABSTRACT:
A dual path drift eliminator and method is provided which effectively removes entrained water particles from high velocity moist airstreams leaving a crossflow cooling tower fill structure by the use of spaced, cellular, individually draining, diversion path-defining structures strategically located and arranged to facilitate maximum drift elimination. The drift eliminator has a plurality of elongated air passages therein disposed to first divide the moist air from the tower fill into a series of separate streams which are first diverted at an upward angle relative to the initial path thereof, and thereafter rediverted laterally to one side of the first diversion path. Water particle removal is thus greatly enhanced by virtue of increased impingement of the entrained particles against the cellular walls defining the respective diversion paths. The eliminators hereof have special advantages in crossflow cooling towers because the spacing between the diversion path defining cellular structures permits separate draining of the water collected in each, so that air inlet blockage resulting from the accumulated drainage of large volumes of water from a single drainage area is avoided. The eliminator structure preferably includes a number of juxtaposed pairs of spaced, elongated, transversely corrugated, preformed sections sandwiched between elongated, preformed, transversely V-shaped panels to define a structurally distinct eliminator pack which can be manufactured using assembly line techniques; such packs are moreover of nestable configuration permitting complemental positioning of a plurality of packs to present a substantially continuous drift eliminator unit free of objectionable vertical gaps, notwithstanding the lack of conventional shiplap joints or other mechanical interconnection between individual eliminator packs.
