| Abstract: |
| 【Objective】The optimal operating conditions of pre-pump micro-pressure filter are explored. 【Method】In this paper, the pre-pump micro-pressure filter was taken as the research object, and the head loss, sand interception quality and total filtration efficiency were taken as the assessment indexes. Orthogonal experiments of the physical model of the inlet flow, sediment content, water separator type, and filter area were conducted. The experimental results were processed by analysis of range, analysis of variance. 【Result】The influences of the factors affecting the muddy water head loss in descending order are inlet flow, the sediment content, filter area, and water separator type. The influences of the factors affecting the trapped sediment mass in descending order are the sediment content, filter area, water separator type, and inlet flow. The influences of the factors affecting the total filtration efficiency in descending order are the filter area, sediment content, water separator type, and inlet flow. 【Conclusion】The two main factors that affect head loss, trapped sediment mass and total filtration efficiency are sediment content and filter area. Comprehensive analysis shows that the best operating conditions are (sediment concentration: 0.36 kg/m3, flow rate: 4 m3/h, water separator type: type 3, and filter area: 2060 cm2). |
