| titleOfInvention | Method for producing high-purity sodium sulfite and sodium sulfate by desulfurizing coal-fired flue gas through alkaline method |
| abstract | The invention discloses a method for producing high-purity sodium sulfite and sodium sulfate by desulfurizing coal-fired flue gas through an alkaline method. A two-stage desulfurization process is adopted; first-stage desulfurization refers to coarse desulfurization in which sulfate is left in first-stage desulfurizing liquid, sodium sulfate is produced, and most of sulfur dioxide in flue gas enters second-stage desulfurization; the second-stage desulfurization refers to main desulfurization in which flue gas can be exhausted up to standard, and the desulfurizing liquid can be directly concentrated and crystalized to produce high-purity sodium sulfite. The method has the advantages of being simple in process and easy to implement; sulfur dioxide in low-concentration flue gas is recycled by adopting the two-stage desulfurization process, so that secondary pollution caused by desulfurization and zero emission are eliminated completely; 95-percent high-purity sodium sulfate and 95-percent high-purity sodium sulfite are produced by using sulfur dioxide flue gas, and sodium sulfite accounts for 90-95 percent, so that the conventional treatment way of pure resource consumption is changed, the desulfurization burdens of enterprises are relieved greatly, and even desulfurization is turned into value-added production, thus remarkable technical and economical effects are achieved. |
