| 摘 要： | 摘要：结合选煤厂煤泥水的沉降设备，建立数学模型计算出颗粒的沉降时间为63s。进行煤泥水絮凝沉降试验，研究煤泥水的沉降时间对沉降效果的影响，结果表明沉降时间为60s是合理的，沉降时间过长意义不大。

| Abstract: | Abstract: A numerical model of particle settlement in a settlement separator for coal slurry was established, through which a particle sedimentation time of 63 seconds was obtained. Then a series of flocculation experiments were conducted to study the effect of sedimentation time on settlement performance. The results show that a length of sedimentation time of 60 seconds is reasonable and it is meaningless to have a longer one. |
