available. It provides maximum separation efficiency for the smallest space impact of the available technologies. Principle of Operation Hydrocyclones operate under system pressure and use pressure drop as the primary source of energy. Each hydrocyclone liner in a vessel is fed tangentially to initiate a high radial velocity.
Cyclone Collection Efficiency: Comparison of Experimental Results with Theoretical Predictions John Dirgo* and David Leitht Harvard School of Public Health Physical Sciences and Engineering Program 665 Huntington Avenue Boston MA 021 15 This paper describes the results of tests conducted on a Stairmand high-efficiency cyclone.
hydrocyclone in the split ratio and reduced particle were diameter of the cylinder section overflow diameter underflow diameter inlet height vortex finder length and the length of the conical region . They found that the variables with statistical significance regarding separation efficiency were overflow and underflow diameters.
A high efficiency hydrocyclone for separating liquid constituents of a mixture wherein one constituent is a dispersed phase in another continuous phase constituent. The separation chamber of the hydrocyclone is configured such that a first steep tapered or curved portion progresses to a second less steeply tapered or curved portion with the beginning of such second less tapered portion being
Φ660mm hydrocyclone. The classifi ion efficiency was increased obviously by optimizing the operational and structural parameters of the hydrocyclone. INTRODUCTION Hydrocyclone has been widely used in many areas of separation due to the advantages of its low operating cost high throughput low space requirement etc and it’s used

A high density cleaner with diameter ranging from 15 to 50 cm 6–20 in is used to remove tramp metal paper clips and staples and is usually positioned immediately following the pulper. As the cleaner diameter decreases its efficiency in removing small sized contaminants increases.
A high efficiency small diameter hydrocyclone for separating liquid/liquid constituents of a mixture. An effective separation portion L e of the hydrocyclone separation chamber begins at a small diameter throat D T where acceleration and velocity of the mixture cease to increase. This effective portion L e ends at the underflow outlet from the separation chamber and has an area to volume
Therefore small diameter cyclones require a multiple of units in parallel for a given capacity. Reducing the gas outlet diameter results in an increased collection efficiency and ΔP. High-efficiency cyclones have cone lengths in the range of 1.6 to 3.0 times the cyclone diameters. Collection efficiency increases as the gas throughput increases.
