Analysis of minimum specific energy consumption and optimal transport concentration of slurry pipeline transport systems
文献摘要：
Slurry pipeline transport is widely used in several industrial processes.Calculating the specific power con-sumption(SPC)and determining the best working conditions are important for the design and operation of transportation systems.Based on the Shanghai Jiao Tong University high-concentration multi-sized slurry pressure drop(SJTU-HMSPD)pipeline-resistance-calculation model,the SJTU-SPC model for cal-culating the power required to transport a unit volume of solid materials over a unit pipeline length is established for a slurry transport system.The said system demonstrates a uniformity coefficient in the 1.26-7.98 range,median particle size of 0.075-4 mm,particle volume concentration of 10-60％,and pipeline diameter of 0.203-0.8 m.The results obtained were successfully verified against existing experimental data.The influence of parameters,such as particle-gradation uniformity coefficient,median particle size,pipe diameter,and particle volume concentration,on the SPC were analysed.The results revealed that the greater is the uniformity coefficient,the smaller is the minimum specific energy con-sumption and the larger the optimal transport concentration for a constant,median particle size slurry.As observed,the optimal transport concentration for broad-graded sand equalled approximately 48％.These results supplement the conclusions of existing research,indicating that the optimal transport con-centration is approximately 30％and provides theoretical support for high concentration transportation of broad graded slurry.
