The sulfuric acid vacuum concentration device comprises a reaction kettle and a tantalum tube heater, and the left side wall and the right side wall of the reaction kettle are fixedly connected with a feeding port and a discharging port respectively. According to the invention, dilute sulphuric acid overflows into the reaction kettle and is heated, boiled and evaporated through the tantalum tube heater, and in the evaporation process, the motor rotates to drive the driving wheel, the deflector rod and the roller to drive the deflector plate to reciprocate, so that the rotating shaft drives the two groups of stirring blades to swing back and forth in acid liquor, and the fluidity of the acid liquor is improved; the acid liquor is in better contact with the surface of the tantalum tube, the condition of non-uniform heating is avoided, the boiling evaporation efficiency is improved, and the concentration of the acid liquor in the last-stage concentration chamber is very high under the same process and time. 本发明公
