基于计算流体力学理论,提出一种可用于预测双套管密相气力输送系统能耗的新方法.与以往依靠经验的计算方法不同,本工作将输送管道分为起始段与充分发展段两部分,分别进行详细的计算流体力学模拟后汇总得出整个系统的总能耗.压力梯度为750 Pa/m的情况下,计算所得物料输送速率为10 t/h,耗气量为290 m~3/h,实验所得物料输送速率为8.0 t/h,耗气量240 m~3/h,证明本数模方法是可靠的. |

A new method based on CFD(computational fluid mechanics)is used to estimate the energy consumption of DTS (double-tube socket)pneumatic conveying.The whole pipeline is divided into developing and fully developed parts.After CFD simulation of both parts the overall energy consumption is calculated.The results show that under the pressure gradient of 750 Pa/m in the developed part the predicted material flow rate is 10 t/h and the measurement material flow rate 8 t/h.Meanwhile the predicted gas consumption is 290 m~3/h and the measurement gas consumption 240 m~3/h.The predicted results are in fair agreement with the experimental results,suggesting that the new method is reliable and applicable. |
