Title:
DEVICE FOR MANUFACTURING RECYCLED CARBON FIBERS, AND METHOD FOR MANUFACTURING RECYCLED CARBON FIBERS
Document Type and Number:
WIPO Patent Application WO/2013/032027
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provided a manufacturing method and a manufacturing device that use carbon fiber reinforced plastic (CFRP) as a source material for the efficient, low-cost manufacture of recycled carbon fibers exhibiting excellent ease of handling. [Solution] A device for manufacturing recycled carbon fibers is provided with: a dry distillation-carbonization furnace (101) having a box-shaped main body (105), a dry distillation-carbonization chamber (102) which accommodates CFRP (40), a combustion chamber (103) equipped with a burner (104), and a heating chamber (115) formed in the space between the main body (105) and the dry distillation-carbonization chamber (102); and a continuous furnace (26) that continuously heats the CFRP (25) that has been dry distilled and removes a portion of the fixed carbon. The device for manufacturing recycled carbon fibers is characterized by the provision of a vapor generator (105) to the dry distillation-carbonization furnace (101), and by the supply of steam at a temperature of 100°C-700°C to the dry distillation-carbonization chamber (102).
