| description | The invention discloses a production system for synchronously preparing sulfuric acid and nitric acid from flue gas of a thermal power plant boiler, which comprises sulfur dioxide absorption and oxidation equipment, circulation equipment, evaporation and crystallization equipment, heating equipment, solid separation equipment, storage equipment and lifting equipment which are connected through pipelines, flue gas enters the sulfur dioxide absorption and oxidation equipment through a pipeline and is in full contact with contained absorption liquid, so that sulfur dioxide in the flue gas is absorbed, and then purified flue gas overflows from the top and is discharged; the absorption liquid absorbing the sulfur dioxide falls to the oxidation zone below again to be in contact with oxygen in the introduced air, so that sulfurized components in the absorption liquid are fully oxidized; after the wet sulfur is dried, 1lt of sulfur is obtained; and packaging the% sulfur product in a packaging machine to obtain commer |
