| 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. |
