摘要
通过改变垂向异重流式水沙分离鳃中鳃片间间距以及鳃片与分离鳃纵向侧壁的间距,利用不同含沙浓度的水在垂向异重流式水沙分离鳃中进行泥沙的沉降实验。对实验中泥沙在两种不同鳃片间距的分离鳃中的沉降现象进行比较分析,确定了鳃片间间距越小,水沙分离效果越好;鳃片与侧壁间距越小,水沙分离效果越好,但太小又可能会造成泥沙淤积,不易清除。
The present study was to carry out the settlement test of sediment with different concentra- tions of sand in vertical component density flow water-sediment separation device, through the change of the spacing of the gill-piece between the gill-piece and the spacing of the gill-piece of the longitudinal side-wall in the vertical-component density flow water-sendiment separation device. The contrast analysis was conducted on the silt subsidence in the two different spacing of the gill-piece of the separation device. It was determined that the smaller the spacing between the gill-pieces is,the better the effect of the water-sedi- ment separation is;But the sendiment would he deposited,if the spacing of the gill-piece between the longi-tudinal sidewall was too small.
