HEAT-AND-MASS EXCHANGE VORTEX COLUMN Russian patent published in 2012 - IPC B01D3/30 B01D53/18 

FIELD: process engineering.

SUBSTANCE: proposed column comprises still section, cover, vertical body composed of shell sections and trays with horizontal webs alternating over their height. Top trays have central overflow and outer drain barrels while bottom trays are provided with outer overflow barrel and drain branch pipe. Tray horizontal webs accommodate vapor (gas) swirlers comprising different-diameter spaced apart distribution discs with extra tangential shaped plates arranged on their surface to make vapor passages. Relation between distances H_i and L_i from top edges of drain branch pipe and outer drain barrel to the surface of distribution disc and radial distance between distribution discs δ is kept equal to H_i/δ = L_i/δ = 1.25-10. Relation between radius R_"б" of circle whereon seat outlets of shaped discs and radius R_K of circle crossing the center of perpendicular connecting two shaped plates in the least cross-section of vapor (gas) passage for top tray makes R_"б"/R_K= 0.8-0.96 and for bottom plate it equals R_K/R_"б" = 0.8-0.96.

EFFECT: higher efficiency
