Document Type and Number:
WIPO Patent Application WO/2024/071035
Kind Code:
A1
Abstract:
The present invention prevents ignition and explosion in a connecting pipe. A regeneration system 1 in the present invention comprises: a thermal decomposition apparatus 10 for thermally decomposing scraps of molded bodies obtained by molding a (meth)acrylic resin composition containing a (meth)acrylic polymer, the thermal decomposition apparatus comprising an introduction unit 12 for introducing scraps, and a gas discharge unit 14 for discharging a methyl (meth)acrylate-containing gas generated by the thermal decomposition of the (meth)acrylic resin composition; and a gas treatment apparatus 30 which is connected to the gas discharge unit 14 via a connecting pipe 20 and which includes at least one type selected from the group consisting of a refining unit for refining a gas discharged via the connecting pipe and a cooling unit for cooling the gas. The connecting pipe includes at least one pipe main body 22A, and at least a partial region of the pipe main body has a cooling unit 24 for cooling a gas that passes through the pipe main body.
