FIELD: devices for mass-transfer processes, such as absorption, rectification, moistening, in particular, in processes of vacuum rectification in chemical, petrochemical food and other branches of industry. SUBSTANCE: to set up an ordered rotary motion of gas-liquid flow within each contact members, the column is furnished with contact members in the form of truncated cones perforated by arched holes, staggered on plates; the cone bases are secured in the upper plate, and the cone vertices with windows are secured on the lower plate; the cone bases project over the plate plane and have slots, and the arched holes are arranged on the cones in horizontal rows and directed to the same side. EFFECT: enhanced efficiency of mass transfer and capacity in vapor phase. 1 cl, 1 dwg |
