动水中浑液面升降规律试验研究

本试验在同一“装置”结构中，不同进流含沙浓度下，通过改变进流流量的大小，对“装置”中的浑液面升、降进行调控。根据“装置”内泥沙浓度分布的不同，将其分为四个区：清水区、低于进流含沙浓度的非拥挤沉降区、拥挤沉降区、压缩沉降区；并且分析了浑液面的升降与进流流量之间的关系，得出浑液面的升降规律。根据浑液面升降过程的调控，可求出“装置”在某一进流含沙浓度下的清水出水量，其研究结果可以为弄清“装置”水沙分离的物理机理提供理论依据。

Experimental Research on Law of Interface Ascending-Descending in Moving Water

Through changing the inlet discharge and different sediment concentration of inflow in the same structure of the turbid water hydraulic power separation device, the experimental researches on the ascending-descending of the turbid-water interface between clean water and turbid water are carried on in this paper. There are four zones, i. e. , clean water zone, non-congested sediment zone, congested sediment zone, compressed sediment zone, in the turbid water hydraulic power separation device. The relationship between the ascending-descending of the turbid-water interface is analyzed, and the law of interface ascending-descending is found out. According to the control process of the ascending-descending of the turbid-water interface, the outlet discharge of the discharge at a sediment content of inflow water can be calculated. Its findings can provide the theory basis for the physical mechanism study of separation clear water from turbid water in the device.
