MASS-EXCHANGE COLUMN LIQUID DISTRIBUTOR AND METHOD OF ITS MOUNTING AND USE Russian patent published in 2006 - IPC B01D3/32 B01D53/18 B01F3/04 

FIELD: liquid distributors for mass-exchange columns.

SUBSTANCE: proposed liquid distributor is used for distribution of liquid in lower mass-exchange layer consisting of several disordered, grid-type or structurized elements of packing. Liquid distributor is provided with many extended chutes separated from one another and laid across the column. Side walls of chutes have many liquid drain holes located in one or several planes at definite distance from chute bottom. Reflecting shields are located on the outside of chute side walls; they receive liquid through upper parts. Lower parts of reflecting shields form narrowed outlet hole located in plane below chute and used for draining liquid from reflecting shields to lower mass-exchange layer. Liquid drain holes in one of side walls of chute are displaced relative to the like holes in other side wall of chute for smooth distribution of liquid in outlet hole. Position of reflecting shields may be regulated vertically; they shall be supported by upper surface of mass-exchange layer so that liquid should be fed directly to mass-exchange layer, thus decreasing probability of entrapping falling liquid by vapor flow ascending through mass-exchange layer. Liquid escaping from outlet hole forms flow in form of curtain excluding penetration of vapor into outlet hole. Vapor admitted to outlet zone may be discharged upward through opening between shields and respective chutes at reduced velocity, thus excluding entrapping of liquid. Said opening is used for entrapping any liquid escaping from chutes by draining it downward over inner surface of reflecting shields.

EFFECT: enhanced efficiency.
