Column comprising liquid distributors and mass transfer trays made up of angle profiles

摘要

The invention relates to a column, comprising: a shell (10), which is made to extend along a longitudinal axis (L) and encloses an interior space of A column (1, 2, 3, 4), at least one mass transfer tray (100), which is made to extend along the column cross section (Q) of the column (1, 2, 3, 4) running transversely to the longitudinal axis (L), and at least one liquid distributor (200, 300), which is designed to apply a liquid phase (F) to the at least one mass transfer tray (100). According to the invention, it is provided that the mass transfer tray (100) has a plurality of run-off elements (101), in particular in the form of angle profiles, which run parallel to one another and at a distance from one another and respectively extend along the column cross section (Q), wherein the run-off elements (101) respectively have a first and a second run-off surface (102a, 103a), which is made to extend along the column cross section (Q), and wherein the two run-off surfaces (102a, 103a) run towards one another along the longitudinal axis (L) in the direction of the liquid distributor (200, 300) and meet to form an edge (104), which is made to extend along the column cross section (Q), and wherein the liquid distributor (200, 300) is designed to impart the liquid phase (F) to the edges (104) of the run-off elements (101), and so the liquid phase (F) imparted to the respective run-off element (101) flows off from the respective run-off element (101) to both sides of the respective edge (104) by way of the run-off surfaces (102a, 103a).
