Title: DEVICE FOR DRYING AND RECOVERING CARBON NANOTUBE PRODUCT AND METHOD FOR MANUFACTURING CARBON NANOTUBE USING SAME
Abstract:
The present invention relates to a device for drying and recovering a product such as a carbon nanotube pellet or an aggregate, wherein not only a drying column interior and an outer heat source, but a high-temperature gas is introduced/dispersed into the column, making it possible to accelerate solvent evaporation, and the evaporated solvent can be quickly removed. In addition, the flow of the product inside the column is controlled by adjusting the gas flow velocity such that drying and recovering processes can be performed while minimizing damage to the product. Therefore, the present invention can be effectively applied to mass production of the carbon nanotube pellet product.
