Title:
EXTRUDER FOR THERMAL DECOMPOSITION, THERMAL DECOMPOSITION SYSTEM, MANUFACTURING METHOD OF DECOMPOSITION GAS, AND DISCHARGE METHOD
Document Type and Number:
Japanese Patent JP2022127346
Kind Code:
A
Abstract:
To provide an extruder for thermal decomposition which is capable of suppressing a decomposition gas generated by thermal decomposition of a polymer to be discharged from a hopper hole, and a manufacturing method of a decomposition gas.SOLUTION: In an extruder for thermal decomposition 10, a hopper 14 is cylindrical. A bottom edge of the hopper 14 is attached to a transportation part 11. By these, an internal space of the hopper 14 is connected to an internal space of the transportation part 11 (cylinder 10) via a hopper hole 11a. A side wall of the hopper 14 is provided with a discharge hole 14b. The discharge hole 14b is penetrated through the side wall of the hopper 14. Thus, the discharge hole 14b is connected to the internal space of the hopper 14, and a decomposition gas generated on thermal decomposition of a polymer is discharge to outside of the hopper 14.SELECTED DRAWING: Figure 6
