Equipment for evaporative towers with giant walls

摘要

A wetted wall structure for use in a cooling tower of the evaporative type wherein water flowed downwardly over the walls arranged vertically is cooled by air flowing between the walls comprises, for each wetted wall, a vertical splash-plate to the bottom edge of which is attached a non-woven grid consisting of parallel spaced vertical rods and parallel spaced horizontal rods. The water to be cooled issues from one or more supply pipes, depending upon the width of the splash-plate, its velocity and the angle of impingement on the plate, spreads gradually as it flows downwardly over the plate and thence flows downwardly over the grid in an unbroken film.
