Claim:
1. An apparatus for producing a carbon nanotube fiber, comprising: a vertical reactor having a reaction zone; a spinning solution inlet through which a spinning solution is introduced into the bottom of the reaction zone of the reactor; a carrier gas inlet through which a carrier gas is introduced into the bottom of the reaction zone of the reactor; a heater that heats the reaction zone; a discharge unit disposed on the top of the reaction zone and through which a carbon nanotube fiber is discharged from the reactor; and a distribution plate placed below the reaction zone of the reactor to divide the reactor into an upper reaction zone and a lower non-reaction zone in fluid communication with each other, and the spinning solution inlet and the carrier gas inlet are disposed above and below the distribution plate, respectively, wherein the spinning solution entering the reaction zone through the spinning solution inlet is carbonized and graphitized while ascending from the bottom of the reaction zone by the carrier gas entering through the carrier gas inlet, to form a carbon nanotube fiber consisting of continuous aggregates of carbon nanotubes, and wherein the carbon nanotube fiber discharge unit has a winder that winds and collects the carbon nanotube fiber discharged from the top of the reactor.
