摘 要:
采用物理模型试验方法,开展了相同含沙量下不同流量的分离鳃和普通管水沙分离效率试验.试验结果表明:动水条件时,分离鳃中也出现了垂向和横向异重流现象;当含沙量为10 kg/m~3时,分离鳃在浑水进口流量为0.3、0.5、0.7、0.9、1.1 m~3/h条件下,水沙分离效率是普通管的1.03~2.26、1.16~2.45、1.30~2.70、1.58~3.85、1.65~1.60倍;分离鳃的最佳浑水进口流量为0.9 m~3/h,水沙分离效率可达34.12%,耗水率为5.78%;浑水进口流量为0.3~0.9m~3/h时,分离鳃水沙分离效率随时间的变化可分成缓慢增加、快速增加、缓慢增加3个阶段,而浑水进口流量为1.10m~3/h时仅有缓慢增加阶段.

摘 要:
The physical model test method was used to test the water-sand separation efficiency of gill-piece separation device( GPSD) and common pipe under the same sediment concentration and different flow rates. The experimental results show that the vertical and horizontal heterogravity flow also occurs in GPSD under the condition of moving water. When the sediment content is 10 kg/m~3,the separation efficiency of GPSD is 1.03 ~ 2.26,1.16 ~ 2.45,1.30 ~ 2.70,1.58 ~ 3.85,1.65 ~ 1.60 times of that of the common pipe under the conditions of0.3,0.5,0.7,0.9 and 1.1 m~3/h of the inlet flow of muddy water. The optimal muddy water inlet flow rate of GPSD is 0.9 m~3/h,the water-sand separation efficiency can reach 34.12%,and the water consumption rate is 5.78%.When the inlet flow of muddy water is 0.3 ~ 0.9 m/h,the separation efficiency of water and sediment with time can be divided into three stages of slow increase,fast increase and slow increase,while when the inlet flow of muddy water is 1.10 m~3/h,there is only a slow increase stage.
