| titleOfInvention | Recovery method of zinc component from electric dust and apparatus for same |
| abstract | The present invention injects dust and concentrated sulfuric acid into a rotary reactor such as a kiln, which includes a ball mill, and reacts the dust and sulfuric acid to recover zinc components as zinc sulfate. The furnace and concentrated sulfuric acid are continuously injected, and the reaction mixture passing through the rotary reactor is received by the second hopper 40 and stored in the storage tank 60 through the second screw conveyor, and the storage tank is about 30 to 50 ° C. After storage for one or more days, the mixture was transferred to a second reactor, and then about three times the amount of water was added to the amount of the maximum dust, the mixture was kept at about 70 to 90 ° C, and stirred until the pH was 4 to 4.5. Disclosed is a method for recovering zinc sulfate, which is characterized by filtration separation.n n n In addition, in the method of the present invention, after reacting by a dry method in a rotary reactor in which no water or the like is added, the obtained reactant can be stored, and only zinc sulfate can be recovered from the reactant, if necessary, so that a large amount of dust is continuously treated. High yield, high purity zinc sulfate can be recovered, providing a very economical method. |
