| titleOfInvention | Method for removing high-concentration SO in flue gas by utilizing manganese carbonate ore2Method for producing manganese sulfate solution |
| abstract | The invention provides a method for removing high-concentration SO in flue gas by utilizing manganese carbonate ore 2 The method for preparing the manganese sulfate solution mainly comprises the following process steps: high concentration of SO 2 Flue gas enters from the first stage tower section of the multi-stage spray tower, desulfurization slurry enters from the last stage tower section of the multi-stage spray tower, and meanwhile, continuous grading feeding is carried out on all stages of tower sections to control the pH value and the manganese-iron ratio of the desulfurization slurry in each stage of tower section to be in a proper range, the desulfurization slurry and the flue gas reversely flow among all stages of tower sections of the multi-stage spray tower, and the desulfurization slurry is circularly sprayed in each stage of tower section of the multi-stage spray tower to carry out contact reaction with the flue gas entering from the lower part of the tower section, SO that SO in the flue gas is removed 2 Leaching manganese in the manganese carbonate ore; the manganese sulfate solution product is discharged from the first-stage tower section, and the flue gas after full desulfurization is discharged from the last-stage tower section. The method utilizes ferromanganese to carry out concerted catalytic desulfurization and has SO 2 High oxidation efficiency and low production cost. |
