Abstract
A carbon nanotube synthesis process apparatus comprises a reaction tube in which a reaction field is formed, and a discharge pipe (32) arranged downstream of the reaction tube and discharging carbon nanotubes to the outside. A plurality of nozzles (34) are provided on the sidewall of the discharge pipe (32) in directions which are deflected with respect to the center (O) of the discharge pipe (32). When gases are discharged from the plurality of nozzles (34), a swirl flowing from the inner side surface along the inner side surface is produced in the discharge pipe (32). Adhesion of carbon nanotubes to the inner side surface of the discharge pipe (32) is prevented by the swirl flow and thus the apparatus can be operated continuously.
