通过对水力旋流器压力损失的分段测定,发现旋流腔和锥体段压力损失最大,占总损失的50%以上,其次是入口段,接近40%,而圆柱尾管段所占比例最小,不到10%;而且各段所占比例基本不随流量变化而改变。由于旋流分离的有效压力损失段在旋流器内腔,并非在入口处,因此减小入口段压力损失是降低水力旋流器无效能量损耗的突破口。利用非金属材料水力旋流器进行试验,找出了有效降低水力旋流器压力损失的方法,试验结果证明,加大水力旋流器入口截面尺寸可有效降低总压力损失,而其分离效率基本不受影响。
The pressure loss of the hydrocyclone was found to be the largest one, accounting for more than 50% of the total loss, followed by the inlet section, which was close to 40%, while the proportion of the cylindrical tail section was the smallest , Less than 10%; and the proportion of each section basically does not change with the flow changes. Because the effective pressure loss of cyclone separation is in the cyclone cavity, not at the entrance, reducing the pressure loss in the entry section is a breakthrough to reduce the loss of the hydrocyclone’s ineffective energy. The non-metallic hydrocyclone was used to test and find out the effective way to reduce the pressure loss of the hydrocyclone. The experimental results show that increasing the cross-sectional size of the hydrocyclone can effectively reduce the total pressure loss, while the separation efficiency Not affected.
