The invention discloses a
titanium purification device. The
titanium purification device comprises a purification bag, a high-pressure and high-temperature
inert gas device, a heating device and an exhaust duct, wherein the purification bag is of a closed tank structure, a
crucible is arranged in the purification bag, a gap between the
crucible and the purification bag is filled with a
thermal insulation material, and a cooling device is embedded in the
thermal insulation material; an outlet of the high-pressure and high-temperature
inert gas device penetrates through the bottom of the purification bag and the
thermal insulation material to be communicated with the bottom of the
crucible, and a liquid outlet
pipe extending out of the purification bag is arranged at the bottom of the crucible; the heating device comprises a middle heater, the upper end of the middle heater is fixed at the top of the purification bag, and the lower end is arranged in a cavity of the crucible; and the exhaust duct is arranged at the top of the purification bag. According to the
titanium purification device, preheated
inert gas blown from the bottom has a stirring effect on a titanium solution, enabling the surface titanium solution and inner titanium solution to have
mass exchange continuously, so that impurities in the titanium solution rise to the liquid level, and volatile impurities are removed.
