A depolymerization system with a tube-wound heat exchanger () comprises a heat exchange device for heating a material, having a material output; a gas-liquid separation device () having an inlet and a gas output, connected to the material output of the heat exchange device; and a depolymerization device () connected to the gas output of the gas-liquid separation device (); the heat exchange device comprises at least one tube-wound heat exchanger (). The depolymerization rate is greatly improved and the service period of the whole depolymerization system can be greatly improved.
