COLUMN-TYPE EXTRACTOR WITH REGULAR COUNTERCURRENT PACKING

摘要

FIELD: machine engineering.;SUBSTANCE: column-type extractor with regular countercurrent packing includes a body, a feed union and a solvent, unions for withdrawal of raffinate and extract solutions, union for introducing auxiliary process flows, collectors for input of dispersed heavy and light phases, devices for determination of phase boundary, support grids conjugated with extractor body, on which the packs of regular countercurrent packing are placed. Each pack of regular countercurrent packing is made of alternating flat cut-through and corrugated cut-through sheets contacting each other, and installed vertically and parallel to each other with formation of free channels and fastened with the help of horizontal studs passing through coaxial holes of metal alternating flat cut-through and corrugated cut-through sheets and fixed by nuts, the cut-through of metal alternating flat cut-through and corrugated cut-through sheets is made in the form of rhombus with width b and height h, where hb, raw material and solvent are introduced into the column-type extractor according to one of the four variants depending on their density and flow rate.;EFFECT: reduced metal capacity of the structure.;11 cl, 6 dwg, 6 tbl
