ABSTRACT:
Improved apparatus for distributing a liquid in film form in the interior of vertical tubes in which a counterflow or cocurrent flow of liquid-vapor takes place. The apparatus includes a cylindrical body having an annular ledge and helical grooves on its peripheral surface, and wherein the cylindrical body is slightly tapered downwardly and inwardly to enable it to be easily introduced into the tube and to enable it to be freely rotated about its own vertical central axis. In the case of counterflow circulation, the cylindrical body has a blind laterally perforated vent tube on its top surface. In each instance the rotation of the body is effected by the liquid being distributed to inhibit the formation of deposits of solids from the liquid being distributed on the inner wall of the vertical tube.
