Through this period of understanding, I believe you are no stranger to desulfurization hydrocyclone, but for customers who want to further understand the relevant knowledge of this product, these contents are not enough. Today, I will share with you the knowledge of desulfurization hydrocyclone oil removal, hoping to arouse your attention and let you have a deep understanding of desulfurization hydrocyclone. In this way, we can also know when we buy and use the desulfurization hydrocyclone. We hope it can enlighten and help you. Take a look at the following details:
In fact, it is very simple that the desulfurization hydrocyclone realizes oil-water separation by using the density difference between oil and water and under the action of unequal centrifugal force when the liquid flow rotates at high speed.
Firstly, when the oily sewage enters into the vortex section of the cylinder tangentially, it flows along the axial spiral state of the hydrocyclone. When the fluid enters the parallel tail section, due to the constant velocity flow of the fluid, a certain amount of back pressure is generated on the upper section, so that the low-pressure oil core is discharged to the overflow port, and the water is discharged from the purified water outlet. In the concentric reducing section, because of the contraction of the conical section, the fluid speed increases, and the spiral flow pattern formed flows forward. Due to the density difference between oil and water, the water circulates along the pipe wall, and the oil droplets move to the middle. When the fluid enters the thin cone section, the cross-section decreases continuously, the flow rate continues to increase, and the small oil droplets continue to move to the middle to form an oil core.
For liquid-liquid hydrocyclone, to realize liquid-liquid hydrocyclone separation, it is necessary to have strong swirling flow, to make the dispersed phase have enough radial migration, the diameter of desulfurization hydrocyclone should be small and have enough length diameter, which is more stable than the liquid flow layer near the oil core, and avoid the re mixing of oil and water. The desulfurization hydrocyclone should have a small conical angle, which can make the liquid flow produce a good flow diversion at the rotating mouth, and the rotating shaft should coincide with the geometric axis of the desulfurization hydrocyclone.
