The invention discloses a device and method for preparing high-purity titanium metal through molten salt electrolysis-high-temperature distilling, and belongs to the field of preparing high-purity titanium through an electrochemical method. The method comprises the following production steps that a titanium containing halide electrolyte is added in an electrolytic bath for premelting, and then, heat preservation is conducted under the argon atmosphere; liquid metal (bismuth, tin, lead and the like) serves as a cathode, titanium sponge or soluble titanium containing matter (titanium carbon oxygen solid solution and the like) serves as an anode, and electrolysis is conducted; and after electrolysis is finished, a cathode titanium alloy product is subjected to high-temperature distilling, andfinally, the high-purity titanium metal is obtained. The method has the characteristics that energy consumption is low, the equipment is simple, the production period is short, and the titanium yieldis high. Through the method, impurities in the anode can be effectively removed, the low-oxygen high-purity titanium metal is obtained, and the good application prospect is achieved.
