1250179 V. INSTRUCTIONS (1) ______ TECHNICAL FIELD OF THE INVENTION: The present invention relates to polystyrene styrene, that is, a foaming polystyrene system, particularly a foamed styrene gel, It is used to separate/recover the polyphenylene processing system which is obtained by melting the solvent. Polystyrene condensed with styrene and solvent. Previously, most of them are known as expanded polystyrene because of the shock absorption and squeezing (styr0f0am). It is widely used as a pancake for foods and pots = j: and because of its light weight, most of the wide ethylene is used at the same time. The above-mentioned foamed polyphenylene is mainly used as a burning place; and the problem of harmful gases such as dioxin is used. ^ , Rare and widely used because of its excellent characteristics, and the price of raw materials is cheap. Therefore, the hair / / line f k /, and use, i 4 take γ π π This bubble can be recycled and the commercial re-recycling to reduce the cost of the ethylene as low as possible. At present, there are various mentions related to the regeneration of expanded polystyrene. For example, Japanese Laid-Open Patent Publication No. Hei 8-85735 discloses a separation method and apparatus for regenerating expanded polystyrene using Er Bi. Japanese Laid-Open Patent Publication No. Hei 8-8 573-5 discloses a method in which an inert gas is mixed in a solvent-dissolved foamed styrene solution, and a polystyrene solution is heated in an inert gas to divide the polystyrene into a solvent. The solvent for dissolving polystyrene is a carbon chloride-based solvent, an ether-based solvent, or an ester-based solvent, a ketone-based solvent.

The sleeve of the evaporation section is heated to evaporate the melted colloidal gel to separate the melted polystyrene and the solvent. ^ at the polystyrene 1 3 · as described in the scope of claim 1 of the separation of the separation device is from the first evaporation section to the third evaporation section of 3; =, where the former formation, the aforementioned first evaporation section Rotating the polystyrene gel from the first screw: moving to the inside while evaporating the solvent to the outer direction of the clever direction by the rotation of the spiral stirring element '^ brother 1 Evaporation flute 9 monument The second evaporation section is by the second spiral type stirring element %, the second spiral type spectrum technique ^ 1 dry and back to the Yu; +, Α μ ^ the rotation of the stirring member makes the aforementioned Polystyrene condensed phosphine ~ The evaporation section side moves to the outside while the above-mentioned dissolved money is dropped. The third evaporation section is the third spiral type stirring element & The rotation of the above-mentioned polystyrene gel is rotated in the front side of the front side of the first two while the above-mentioned molten polystyrene is suspected, [: the diameter is placed in the center of the evaporation section of the ^ 3 evaporation section. B is discharged to the radial elements of the device]; the components are respectively formed into a plurality of arms Vj-moving. The motor of the shaft of the center of the garment can be -J; 5152-5487.PF(Nl);Ph〇ebe • Ptd第38页
