Abstract
A drainage collection system for use in an evaporative cooling tower is disposed transversely within a cooling tower below a gas/liquid heat exchanging contact body to receive liquid gravitating therefrom and to collect the same. The drainage collection system includes a plurality of liquid collection plates which are arranged in parallel and inclined from the vertical. Each of the plates includes an upper and a lower end portion with the upper end portion of each overlapping the lower end portion of a respectively adjacent plate. Each plate is shaped over its central portion to form substantially planar upper and lower sections. The lower section is inclined less from the vertical than the upper section. The lower end portion of each of the plates is shaped to form primary and secondary collecting channels extending substantially across the width of the plate for collecting liquid directed thereto by the plate. The primary and secondary collecting channels have outlet ports formed therein for the drainage of liquid collected thereby. The drainage collection system also includes a support frame for the collection plates. The frame includes substantially vertical side supports dispo…
