Abstract

A bubble cap tray (1) for a distillation column (20) of the reaction fluid in the production of soda ash using the ammonia method comprising a liquid trough (2) with an inner opening (3) of the bubble cap tray (1), an inner cap (4) with an active circumference L1 and external overflows (5), the inner cap (4) being positioned above the inner opening (3) so that the active circumference L<1> of the inner cap (4) is above the liquid trough (2). The bubble cap tray (1) for the distillation column (20) according to the invention is characterized in that the active circumference L<1> of the inner cap (4) is droplet-shaped, and the said bubble cap tray (1) further comprises an interrupted outer ring (6) for fixing on the side wall (21) of the distillation column (20) with its outer edge (7), and within the interruption of the outer ring (6) external overflows (5) are arranged, whereby the diameter of the outer edge (8) of the liquid trough (2) is smaller than the diameter of the outer edge (7) of the outer ring (6), and the liquid trough (2) is arranged so that the active circumference L<2> of the outer ring (6) is above the liquid trough (2), and so that, after assembly of the bubble cap tray (1) in the distillation column (20), there is an outer gap (9) between the outer edge (8) of the liquid trough (2) and the side wall (21) of the distillation column (20). Advantageously, the bubble cap tray (1, 1', 1") for the distillation column (20) according to the invention also has an element for adjusting the liquid level in the liquid trough (11), and a closable desludging gap (13) for removing solids deposited at the bottom of the liquid trough (2).
