| 摘 要： | 采用小型间歇消化装置,用正交试验法研究消化参数对石灰干式消化速度及消石灰结构性能的影响.实验结果表明,消化参数对消化结果的影响从大到小排序为:消化时间＞水灰比＞搅拌速度＞消化水初始温度.优化后的工艺参数:消化时间为5～10 min；水灰比(摩尔比)为1.3～1.6；搅拌速度为250～300 r/min；消化水初始温度为25～45℃.优化工艺参数下制备的消石灰比表面和孔隙率最大可达25.69m2·g-1和75.09％. |

| Abstract: | A set of small batch slaking system was used in experiments for investigating the effects of technological parameters on the dry slaking speed of quicklime and the properties of slaked lime by means of orthogonal experimental method.It is found that the factors impacting the slaking process from high to low are slaking time,water/solid ratio,stirring rate,and initial temperature of slaking water.On this basis,the optimal conditions of the dry quicklime slaking process are proposed to be 5~10 min in slaking ... |
