SECTIONALIZED PACKED TOWER Russian patent published in 1997 - IPC

FIELD: devices of mass-transfer packed towers for interaction of gas(vapor)-liquid systems intended for conduction of the processes of absorption, rectification, gas scrubbing and, in particular, vacuum rectification; may be used in chemical, petrochemical and other industries. SUBSTANCE: tower includes vertical cylindrical body accommodating centrifugal sectionalized perforated lattices and centripetal sectionalizing perforated lattices made in the form of truncated cones. These components are installed by tiers alternately over body height. Lattice perforations are made in the form of arched slots with their convexity directed forward and uniformly spaced over concentric circumference. Packing layer is located at random on each lattice. Packing layer height on each lattice equals to linear sizes of packing member. Attached in cross-section spaces, between walls of tower body and outside edges of centrifugal lattice and internal edges of small base of centrifugal lattices, are screens with meshes smaller than linear sizes of packing members. EFFECT: higher efficiency. 8 dwg
