| Zusammenfassung: | The invention provides a method for drying high-purity sulfur dioxide, which belongs to the technical field of sulfur dioxide production, and specifically comprises the following steps: 1, washing sulfur dioxide gas by a water scrubber, cooling to 0 DEG C in a condenser, and carrying out water-vapor separation; 2, separated gas enters from the bottom of the drying tower to be in full contact with concentrated sulfuric acid to remove moisture, and then is deeply cooled to-15 DEG C to be separated to obtain a high-purity sulfur dioxide product; and 3, the concentrated sulfuric acid is continuously supplemented after being detected by a densimeter, and dilute acid is discharged. The method disclosed by the invention is a continuous drying process, is low in energy consumption, has the product purity of 99.99%, and also has the characteristics of easiness in operation and suitability for large-scale production flow.
