Device for drying and recovering carbon nanotube product and method for manufacturing carbon nanotube using same
The present invention relates to a device for drying and collecting a product such as a carbon nanotube pellet or aggregate, which can accelerate solvent evaporation by inserting and dispersing high temperature gas into a drying column as well as by a heat source inside and outside of the column, and can quickly remove the evaporated solvent. Further, the device can be used for drying and collecting processes while minimizing product breakage by regulating the gas flow rate and controlling flow of the product in the column. Thus, the device can be effectively applied to mass production of a carbon nanotube pellet product.
