Abstract Miniature hydrocyclones have received increasing attention due to their advantages of improved separation precision, low cost, easy operation and high stability. However, because of small treatment capacity of a single mini-hydrocyclone, numerous mini-hydrocyclones need to be connected in parallel to meet capacity of treatment for industrial applications.

The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation.

The pressure drop is a product of the gas flow rate, gas density and cyclone geometry. Pressure drop can be expressed as: DR = Ra Inlet - Ra Outlet. Where: DR = Cyclone Pressure Drop. Ra = Absolute Pressure. Another way to increase a separator's efficiency is to reduce the accept port diameter.
15-04-2006· In a solid–liquid hydrocyclone, pressure drop is normally referred to as the difference between inlet pressure and that in the point immediately after overflow exit. This definition is convenient due to the predominance of overflow rate over the underflow rate and the fact that the overflow in many applications remains the process stream.
