The invention discloses a technique for preparing sulfuric acid from SO2 by non-equilibrium state high-concentration twice conversion. SO2 flue gas is subjected to heat exchange twice through a heat exchanger and enters a first section of a converter to be subjected to conversion reaction; the filling amount of the catalyst for the first section of the converter is reduced so that the flue gas can leave the catalyst layer before reaching the SO2 equilibrium conversion rate; a waste heat boiler is arranged before the flue gas entering a second section of the converter to keep the temperature of the second section of the converter stable; the flue gas flows through the waste heat boiler and the heat exchanger to be cooled, and enters the second section catalyst layer of the converter, and at this time, the flue gas SO2 concentration is lower than 12%; the subsequent technique is equivalent to a conventional 3+1 twice conversion technique; and in the process, the temperatures of the first and second sections of the converter are lower than 640 DEG C. The technique can treat flue gas of which the SO2 concentration reaches 18% so as to lower the gross project investment and operating cost and enhance the steam output of the sulfuric acid waste heat boiler, thereby being an energy-saving consumption-reduction conversion technique.
