Column

摘要

The invention relates to a column, with a jacket, extending along a longitudinal axis, which jacket bounds a first jacket space and a second jacket space arranged over it along the longitudinal axis, a chimney tray, extending crosswise to the longitudinal axis, that separates the two jacket spaces from one another. The at least a first chimney extends from the tray along the longitudinal axis, and projects into the second jacket space. The chimney has a peripheral wall defining an opening, via which the two jacket spaces are connected to one another for gas feed, and a chimney top. On the peripheral wall, a flat impact element is arranged tilted toward the longitudinal axis in such a way that a liquid phase flowing downward from the chimney top along the longitudinal axis strikes the flat impact element diminishing the momentum input of the liquid phase that stands on the chimney tray.

1. A column comprising:
a jacket (10) that extends along a longitudinal axis (L), said jacket bounding a first jacket space (M) and a second jacket space (M′), arranged over said first jacket space (M), along said longitudinal axis (L), a chimney tray (20) that separates the first and second jacket spaces (M, M′) from one another and extends in a direction crosswise to said longitudinal axis (L), at least a first chimney (30) extends from said chimney tray (20) along said longitudinal axis (L) and projects into said second jacket space (M′), whereby said at least a first chimney (30) has a peripheral wall (31) extending along said longitudinal axis (L), which defines an opening (32), via which said first and second jacket spaces (M, M′) are connected to one another for gas feed, wherein said opening (32) is covered by a chimney top (33), in such a way that a liquid phase (F) that flows downward along said longitudinal axis (L) into said second jacket space (M′) is prevented from flowing through said opening (32) into said first jacket space (M), a flat impact element (300) is positioned on said peripheral wall (31) and is arranged tilted toward said longitudinal axis (L) in such a way that a liquid phase (F) that flows downward from said chimney top (33) along said longitudinal axis (L) strikes said flat impact element (300) to diminish momentum input of liquid phase (F) that stands on said chimney tray (20).
