导片锥角和片数对悬锥装置水沙分离效率的影响研究

Influence of cone-angle of vane and the number of vane on sediment settlement efficiency in the device with suspended cone-shaped vanes

通过物理模型试验,将泥沙沉降过程中浑水含沙浓度作为量测指标,通过变量控制法就导片锥角和片数对悬锥装置的水沙分离效率影响情况进行了试验研究。研究结果表明:悬锥装置中导片片数的多少是影响该装置水沙分离效率的主要因素,而导片锥角的大小对装置的水沙分离效率影响不大。

Through physical model experimet, the paper took sediment concentration as a primary measurement standard and studied the influence of the number of cone-shaped vanes and cone angle of vanes in the device on sediment settlement efficiency. The results show that the number of vanes is the main factor affecting the separation efficiency, the size of the cone angle of the vanes has a little effect on separation efficiency.
