Apparatus for producing nanocarbon material and method for producing nanocarbon material

A carbon nanomaterial production apparatus comprising:

• a reaction tube into which raw material gas and carrier gas are supplied and accordingly in which carbon nanomaterial is grown;
• a connection tube that is connected to the reaction tube and through which an aerosol-like mixture of the carbon nanomaterial and the carrier gas passes;
• and
• a collection tube that is connected to the connection tube and collects the carbon nanomaterial from the mixture, wherein
• the collection tube includes:
• a junction, connected to the connection tube, from which, while the carrier gas flows upward, the carbon nanomaterial falls downward by gravitational sedimentation to be separated from the mixture,
• a discharge section that is located above the junction with the connection tube and discharges the carrier gas contained in the mixture to outside, and
• a trapping section that is located below the junction with the connection tube and traps the carbon nanomaterial that is separated from the mixture by gravitational sedimentation.
