Pressure Drop Ratio of Cyclone Separator

The pressure drop ratio of hydrocyclone refers to the ratio of the pressure drop between the inlet and the underflow port of the hydrocyclone to the pressure drop between the inlet and the overflow port, which is an important parameter indirectly related to the pressure drop and pressure. For solid-liquid separation cyclones, the cyclone separation efficiency can be improved by increasing the inlet pressure.

Relationship between pressure drop ratio and structural parameters

1. The influence of overflow diameter on pressure drop ratio

When the split ratio is constant, the pressure drop ratio decreases with the increase of the overflow diameter. The diameter of the overflow port can be adjusted to reduce the split ratio and increase the pressure of the overflow port. For the separation of mixed liquids with different mass concentrations, the split ratio can be changed to adapt to the changes in mass concentration, and the pressure drop ratio can be adjusted by changing the diameter of the overflow at the same time.

2. The effect of small cone angle on pressure drop ratio

When the small cone angle becomes larger, the overflow and underflow pressure drops increase. If the inlet pressure is constant, the overflow pressure and the underflow pressure will decrease. As the pressure drop ratio becomes larger, the overflow pressure drop increases more and the overflow pressure drops very low. In the actual production process on-site, a certain overflow and underflow pressure must be maintained. Therefore, when the small cone angle becomes larger, the inlet pressure increases and the system pressure increases.

3. The effect of large cone angle on pressure drop ratio

The larger the cone angle, the more sensitive the split ratio is to pressure changes. It is also easier to control the split ratio of the hydrocyclone by adjusting the pressure.

4. The influence of inlet size ratio on pressure drop ratio

As the entrance size ratio increases, the starting point of the curve changes from larger to smaller, and the range of change is wider. When the pressure drop ratio reaches the maximum value, the experimental data curves of different inlet size ratios and the pressure drop ratio-shunt ratio basically intersect at one point.

In a conclusion, with certain structural parameters, the pressure drop ratio of the hydrocyclone increases with the increase of the split ratio. When the split ratio is constant, the pressure drop ratio decreases with the increase of the overflow diameter. When the structural parameters of the hydrocyclone are changed, the pressure drop ratio increases with the increase of the small cone angle, while the change of the large cone angle has little effect on the pressure drop ratio. Changing the inlet size ratio mainly affects the starting point of the relationship between the pressure drop ratio and the split ratio.
