APPARATUS FOR SEPARATION OF POLYMERIC MATERIALS FROM HYDROCARBON SOLUTIONS Russian patent published in 1995 - IPC

FIELD: synthetic polymers production. SUBSTANCE: apparatus has vacuum settler with dispergating mixer and with located in its upper part deflectors. Apparatus is provided with liquid ejector made in the form of Venturi tube with inlet and outlet branch-pipes and with branch-pipe, one end of which is linked to liquid ejector at an angle and with other end linked to branch-pipe for pulp of polymeric materials crumbs removal. Lower part of settler has branch-pipe for feeding of polymeric materials crumbs with hydrocarbon solvent and water mixture from lower part of apparatus of second stage of separation. Outlet branch-pipe of liquid ejector is linked with delivery branch-pipe of drawing off pump that removes water from lower part of apparatus of second stage of separation. Outlet branch-pipe of liquid ejector is linked with drawing off branch-pipe of delivery pump that is feeding working liquid with steams of water and hydrocarbon solvent from liquid ejector in upper part of apparatus of second stage of separation. EFFECT: apparatus allows to make effective separation of polymeric materials from hydrocarbon solutions. 4 dwg
