| description | The utility model relates to a combined device for absorbing hydrogen sulfide and removing sulfur dioxide. The combined device comprises a removing unit and a recycling unit, wherein the removing unit is used for removing sulfur dioxide in waste acid generated in a copper smelting and purifying process; the recycling unit is used for recycling hydrogen sulfide gas in a vulcanizing process of the waste acid generated in the copper smelting and purifying process; by adopting the technical scheme, the device disclosed by the utility model has the beneficial effects that the device is simple in structure and convenient to use, the absorption of hydrogen sulfide and the removal of sulfur dioxide are combined together, the normal operation of a waste acid vulcanization process is ensured, the occupied area of the equipment is small, the waste gas amount is not increased after the device is used, and the independent tail gas emission is avoided; and the method is environment-friendly and economical.
