The invention provides a device for industrially producing high-purity titanium through a fused salt electrolysis process. The device comprises a vacuum system (a), a fused salt electrolysis device (b) and a direct-current voltage-stabilization electrolysis power source (c). The device has the beneficial effects of being low in cost, simple in structure, easy and convenient to operate, stable and reliable in industrial production, efficient in production and use and the like. By the adoption of the device, high-purity titanium products with the purity being over 4 N can be produced.
