| titleOfInvention | Method for removing mercury in acid making process by lead-zinc smelting flue gas |
| abstract | The invention relates to a mercury removal method in a lead-zinc smelting flue gas acid making process, which belongs to the technical field of flue gas treatment, and realizes efficient mercury removal in the acid making process by adding a first complexing agent at a first-stage dynamic wave position in a lead-zinc smelting flue gas acid making process, adding a second complexing agent on a gas phase pipeline from an intermediate washing tower to a second-stage dynamic wave position, and adding the first complexing agent at the second-stage dynamic wave position; finally, the mercury content in the sulfuric acid in the dry absorption section is less than 0.002%, the mercury content in the finished acid after standing is less than 0.001%, the requirement of high-class industrial sulfuric acid is met, the mercury removal efficiency of the mercury removal method is stable, the mercury removal process is simple, new equipment is not needed, the adaptability is strong, and the reconstruction of the existing device is facilitated. |
