摘要
A compound hydrocyclone is a new strategy for oil-water separation. It is based on the study of static and dynamic hydrocyclones. In this paper are introduced its geometric traits and separation mechanism. Experiments are carried out about the relationship between geometric parameters & operating parameters and the separation efficiency of the compound hydrocyclone. Under experimental conditions, the appropriate structural parameters optimized are as follows: The rotating grid is of the straight board type, 3 straight vanes with a length of above 95 mm; the diameter of the overflow vent ranges 3-12 mm; the separation efficiency is better when the large conical angle of the static vortex body is about 20° and the small conical angle in the range of 1°-4°. The separation effect is better under the following conditions: The rotary speed is 1,700-2,400 r/min; the disposal capacity is 5.5 m3/h; the loss of working pressure is 0.05-0.25MPa; and the split ratio ranges 5%-15%. The experimental study provides a certain basis for the design and application of the compound hydrocyclone.
