A filler Tower, in particular to the water absorption of SO3 in the sulfuric acid or with a filled Bed supported on a Grid shaped Dome, where the Grid shaped dome is supported on a ring in the shape of L, so that between the external diameter of the grid Dome shaped, and the cover of the filler Tower form a Separation.

摘要

Packed tower (1), preferably for the absorption of water or sulfur trioxide in sulfuric acid, comprises a bed of packaged materials supported on a domed grate (7), through which the sulfuric acid trickles from above, a gas supply pipe (5) provided in the lower region of the tower, a gas outlet provided above the bed, and an acid outlet (4) provided in the lower region of the tower. The domed grate is supported on a L-shaped ring such that a gap is formed between the outer diameter of the domed grate and a mantle (2) of the packed tower.
