Liquid distributor for packing columns

Columns including a liquid distributor, the liquid distributor comprising at least one tubular distributor member including outlet openings for an output of liquid in the form of jets and screens that are arranged ahead of the outlet openings and onto which incident liquid jets are deformed to liquid films flowing off and which screen off the outlet openings against an upwardly flowing gas flow, wherein in the event of a maximum output of liquid, the liquid jets are incident onto the screens at angles that are less than 60°, and wherein each screen has a sigmoid curve in a vertical section and a jet-parallel section, and wherein the sigmoid curve is curved downwardly, wherein a plurality of parallel distributor members subdivides a gas flow flowing upwardly in a column into a plurality of partial flows such that stagnation zones form beneath the distributor members, and wherein drip edges of the screens are arranged inside the stagnation zones.
