MASS-EXCHANGE LATTICE COLUMN Russian patent published in 1997 - IPC

FIELD: designs of mass-exchange columns with contact devices for efficient reaction of gas-vapor-liquid systems in processes of absorption, rectification and gas cleaning; may be used in chemical, petrochemical, gas, food and other industries. SUBSTANCE: column includes vertical body accommodating centrifugal perforated lattices located in tiers. Perforations are made in the form of arch slots. Located between centrifugal lattices are centrifugal lattices with perforations in form of arch slots. Diameters of centrifugal lattices are smaller than the inner diameter of body for liquid running off the centrifugal lattices. Centers of centripetal lattices have holes for liquid running off. Located above centrifugal lattices are baffle perforated disks in the form of truncated cones. Installed above centripetal lattices are baffle perforated cones oriented with their tope upward. EFFECT: higher efficiency. 7 dwg
