Title:

APPARATUS FOR THE SEPARATION AND RECOVERY OF VOLUME-REDUCED POLYSTYRENE RESIN GEL

Document Type and Number:

WIPO Patent Application WO/2004/029113

Kind Code:

A1

Abstract:

The invention provides an apparatus for the separation and recovery of volume-reduced polystyrene resin gel which makes it possible to dispose of a volume-reduced polystyrene resin gel continuously and efficiently and thereby attain the separation and recovery of a solvent and a resin. An apparatus for heating a volume-reduced polystyrene gel under a normal or reduced pressure and thereby conducting the separation and recovery of a solvent and a resin, constituted of a main body (10) which has in the upper part a solvent recovery unit for taking out an evaporated solvent continuously and at the bottom a resin recovery unit for recovering a resin separated from the solvent, pipes (20) which are arranged in the main body (10) and through which a heating medium is made to run, means (14) for introducing a volume-reduced polystyrene resin gel in such a way that the gel comes into contact with the pipes (20), a resin holding section (13) for holding a resin which has come into contact with the pipes (20) and then has run down, means (25) for heating the resin held in the section (13), and means (26) for stirring the resin.
