| 摘 要： | 滤网过滤器是一种特殊的泥沙处理设备,有着比较独特的水力性能。从分析其过滤机理出发,结合实验研究,得出：在浑水条件下,滤网过滤器过滤元件的过水面积应该设计偏大一些,预留一部分的堵塞面积,保证筛网在堵塞到一定程度之前,堵塞对过滤器的局部水头损失增幅的影响不是太大,从而保证在这段时间里系统能够正常工作。初步分析了滤网过滤器的...

| Abstract: | As a kind of special water cleaning equipment,the screen filter has its unique hydraulic performance.In this paper,the authors analyze the mechanism of filtration and combine the experimental study to get the results that under the silt water condition,when the clogging of screen approaches to certain extent,the increasing degree of head loss is obviously strengthen.The head loss of the screen filter is mainly related to these factors,such as the flow,the filtration time,and the sand situation.These factors... |
