The utility model relates to an improved device for analyzing pure sulfuric acid through a distillation method. The improved device comprises a raw material tank, a raw acid pump, an overheated tank, a flattening ball and a purified quartz glass pipe which are connected in sequence, wherein the purified quartz glass pipe comprises a pipe a, a pipe b and a pipe c which are connected end to end; the outlet of the upper end of the pipe a is connected with an air outlet and a diluted acid cooling and recycling mechanism; the lower end of the pipe a is connected with a finished product storing tank; a heating mechanism is arranged inside the pipe c; a dumping tank is arranged at the bottom of the pipe c; a section of connecting pipe is welded between the outlet of the flattening ball and the purified quartz glass pipe in a penetrating manner; one end of the connecting pipe is connected with the flattening ball; the other end of the connecting pipe penetrates through the pipe a, the pipe b and the pipe c in sequence; stepped structures form among the pipe a, the pipe b and the pipe c. According to the utility model, straight raw cid connecting pipes among the purified quartz glass pipe are changed to be Z-shaped pipes or U-shaped pipes, so that the mounting and welding stress can be reduced, and in addition, the Z-shaped pipes or the U-shaped pipes can have the function of expansion joints, so that the damage frequency can be reduced and the driving time can be prolonged.
