FIELD: devices of mass-transfer towers with contact devices for effective interaction of gas(vapor)-liquid systems in the processes of absorption, rectification and gas scrubber; may be used in chemical, petrochemical, gas, food and other industries. SUBSTANCE: lattice tower includes vertical body accommodating centrifugal perforated lattices, with perforations in the form of arched slots and centripetal perforated lattices with perforations in the form of arched slots arranged between centrifugal lattices. Centrifugal and centripetal lattices are installed by tiers. Diameters of centrifugal lattices are smaller than body inner diameter to let liquid flowing from centrifugal lattices. Axes of arched slots of centrifugal lattices are directed at an acute angle to generating lines from center to periphery to the same side. Centers of centripetal lattices have openings to let liquid flow through. Located above centrifugal lattices are deflecting perforated discs in the form of truncated cones with perforations in the form of arched slots. Deflecting perforated cones are installed above centripetal lattices. Perforations of deflecting cone are made in the form of arched slots. EFFECT: higher efficiency. 7 dwg
