FILM APPARATUS Russian patent published in 2005 - IPC

FIELD: apparatus for performing heat- and mass-exchange processes in gas-liquid systems; chemical, food-processing and microbiological industries.

SUBSTANCE: proposed apparatus has housing, horizontal partitions, contact tubes fitted with distributing branch pipes and helical spirals. Mounted in between horizontal partitions forming the gas inlet chamber coaxially with contact tubes and distributing branch pipes secured on lower horizontal partition are gas-and-liquid distributors consisting of plates located radially relative to distributing branch pipes forming slots for flow of gas. Upper end faces of plates are provided with blank secured on horizontal partition; lower ends of plates are lowered into circular clearance formed by inner surface of contact tube and outer surface of distributing branch pipe; at least two plates located near each other are provided with inserts at side end faces which form passage for liquid together with plates; this passage is communicated with chamber for introducing the liquid through holes made in blank. Side surfaces of distributing branch pipes have holes for flow of liquid. Plates of gas-and-liquid distributor are mounted tangentially relative to side surface of distributing branch pipe.

EFFECT: smooth distribution of liquid over perimeter of contact tubes; increased area of passage of liquid into circular clearance; avoidance of deposits on surfaces of distributing branch pipes.
