摘要:

【目的】深入研究鱼雷网式过滤器的水头损失和过滤时间。【方法】浑水条件下，对2种滤网目数的鱼雷网式过滤器分别进行定含沙量和定流量试验，分析了水头损失在不同运行条件下的变化规律。【结果】定含沙量试验中，进水流量在240～300 m3/h范围内持续增大时，水头损失发生急剧变化所需时间逐渐延长，而在300～360 m3/h范围内持续增大时，水头损失急剧变化所需时间逐渐缩短，这是鱼雷部件起到关键作用的缘故；定流量试验中，随进水含沙量增大，过滤器达到预设压差0.10 MPa的时间越短；所有试验条件下，水头损失随过滤时间的推移经历保持不变、逐渐减少和急剧增大3个不同的变化阶段。【结论】鱼雷部件在延长过滤时间方面起到重要的作用；鱼雷网式过滤器的冲洗预设压差值调节为0.04 MPa最宜。

Abstract:

【Objective】 The purpose of this paper is to study the head loss across the torpedo screen filter and the associated filtration time. 【Method】 Experiments was carried out using a muddy water at constant sediment content and constant flow. 【Result】 Under constant sediment content, the time it took the head loss to stabilize increased as the flow rate increased from 240 m3/h to 300 m3/h, while decreased for flow rate between 300~360 m3/h. Under constant flow condition, the time it took the pressure drop to reach △p=0.10 MPa decreased as the sediment content increased. With the change in filtration time, the head loss experienced three different stages: remaining constant, gradually decreasing followed by a sharp rise.【Conclusion】 Torpedo plays an important role in prolonging the filtration time, and the appropriate preset pressure for the torpedo screen filter was 0.04 MPa.
