| titleOfInvention | A kind of calcium hydroxide production technology and system |
| abstract | The invention provides a kind of calcium hydroxide production technology, it comprises the following steps：（1）Feedstock treating：Quick lime raw material is carried out to obtain calcium lime powder after carrying out pulverization process again after vibration processing；（2）Digestion reaction：Calcium lime powder is uniformly thoroughly mixed with water makes calcium lime powder progress digestion reaction obtain calcium hydroxide powder；The digestion reaction includes first order digestion reaction, second level digestion reaction and third level digestion reaction.The technique that the production technology of the calcium hydroxide of the present invention employs three-level digestion, the impurity such as the burning calcium oxide, raw burn calcium carbonate and silica that will be contained by multistage digestion and filtering in raw material are removed, the calcium hydroxide finally obtained has higher purity and whiteness, and utilization rate of raw materials is higher. |
