To analyze the effect of a groove cross-sectional shape on disc filters, a head loss analysis and filtration performance test were conducted using disc filters with different groove shapes (semi-elliptical- and trapezoidal-shaped grooves). Furthermore, the groove shapes were analyzed using field emission scanning electron microscopy and the relationship between flow rate and head loss was derived from the head loss test. Even if the filters were designed with the same mesh standard, the sectional areas of the grooves were different depending on the shape. Therefore, the head loss was compared under the condition that the grooves have the same sectional area by applying the relationship between head loss and sectional area, and a smaller head loss was observed in the semi-elliptical-shaped groove. Additionally, the semi-elliptical-groove-shaped disc filter was evaluated to sufficiently filter the soil particles corresponding to the 120 mesh standard. Therefore, an optimum disc filter can be designed by considering the cross-sectional shape of the disc groove to reduce energy consumption and provide stable filtration. The elliptical groove shape, which is hydraulically advantageous, is preferred for the disc filter design.

槽形对盘式过滤器水头损失和过滤性能的影响

为了分析凹槽横截面形状对盘式过滤器的影响，使用具有不同凹槽形状（半椭圆形和梯形凹槽）的盘式过滤器进行了水头损失分析和过滤性能测试。此外，使用场发射扫描电子显微镜分析了凹槽形状，流量和水头损失之间的关系由水头损失测试得出。即使过滤器采用相同的网格标准设计，凹槽的截面积也因形状而异。因此，应用水头损失与截面积的关系，在槽具有相同截面积的条件下比较水头损失，在半椭圆形槽中观察到较小的水头损失。此外，评价了半椭圆槽形圆盘过滤器对土壤颗粒的充分过滤，符合120目标准。因此，可以通过考虑盘槽的横截面形状来设计最佳盘式过滤器，以降低能耗并提供稳定的过滤。椭圆槽形状具有液压优势，是盘式过滤器设计的首选。
