Sulfur dioxide distillation measuring device

The utility model discloses a sulfur dioxide distillation determination device which adopts the technical scheme that an organic matter decomposition device is connected between an outlet of a condenser and an inlet of an absorption bottle, and the organic matter decomposition device is a high-temperature heater; gaseous distillates in the sample are subjected to high-temperature treatment through the thermal decomposition device and then enter the hydrogen peroxide absorption liquid to be absorbed. For a sample containing the volatile sulfur-containing compounds, the volatile sulfur-containing compounds in the gaseous distillate are decomposed into inorganic sulfur-containing compounds at high temperature, the inorganic sulfur-containing compounds are oxidized into sulfate ions in the absorption liquid, and titration is carried out by adopting an acid-base titration method after the color of the absorption liquid is changed. Therefore, the natural background value of the volatile sulfur-containing compound i
