Abstract

The liquid distributor for columns has liquid outlet openings and fine distribution elements with a guide wall associated with them. A preselectable amount of liquid can be supplied into the associated fine distribution element via each outlet opening. A plate-like element communicating with the guide wall is arranged in each fine distribution element, with a communicating chain of capillary openings forming a distribution zone and drain-off zone between the edge of the element and the guide wall. This chain extends along a horizontal, closed curve.
