1. A packed exchange tower, the packed exchange tower being of a type wherein vapor is injected therein for ascension therethrough and liquid is dispersed therethrough for downward flow, the packed exchange tower comprising:
one or more packing sections disposed in the tower for facilitating the interaction of vapor and liquid passing in a counter-flow therethrough; one or more liquid flow distributors for positioning above the one or more packing sections for even distribution of the liquid downwardly therethrough, the one or more liquid flow distributors including:
a plurality of troughs for dispersing the liquid thereacross, at least one trough of the plurality of troughs being configured for dispersing the liquid in a single-deflecting-member configuration, the at least one trough having along a first side thereto a single deflecting member, the single deflecting member being used in conjunction therewith for maximizing efficiency of vapor-liquid interaction;a diffuser plate extending from the single deflecting member, the single deflecting member discharging the liquid against the diffuser plate for uniformly distributing the liquid across the plurality of packing sections, the diffuser plate extending below the single deflecting member;the single deflecting member having a deflector side facing outwardly of the at least one trough and a diffuser side facing the at least one trough, the single deflecting member being angulated to generally follow a shape of the at least one trough;the deflector side of the single deflecting member being positioned for deflecting ascending vapor away from the downward flow of the liquid on the diffuser side; andwherein the single deflecting member extends along a length of the selected side of the at least one trough and is constructed in a generally reverse L-shaped configuration such that a lower region thereof is generally perpendicular to and spaced from the diffuser plate. |
