Apparatus for continuously producing carbon nanotubes

An apparatus for producing carbon nanotubes comprising:

• a reaction unit in which carbon nanotubes (CNTs) are synthesized;
• a supply unit configured to supply a carbon source to the reaction unit through a supply pipe;
• and
• a collection unit configured to collect carbon nanotubes discharged from the reaction unit,
• wherein the reaction unit comprises a chemical vapor deposition reactor,
• wherein the reaction unit comprises:
• a nozzle member communicating with the supply pipe;
• a reaction tube, into one end of which the nozzle member is inserted, the reaction tube being formed to have a predetermined length along an insertion direction of the nozzle and providing a space in which the carbon nanotubes are synthesized from the carbon source supplied through the nozzle member;
• and
• a chamber formed to have a predetermined length outside the reaction tube and configured to supply heat to the reaction tube to form a reaction area within the reaction tube,
• wherein the reaction unit further comprises a cooling member provided outside one end of the reaction tube into which the nozzle member is inserted, the cooling member being configured to cool heat generated from the carbon source flowing through the nozzle member.
