Hydrocyclones are cono-cylindrical in shape, with a tangential feed inlet into the cylindrical section and an outlet at each axis. The outlet at the cylindrical section is called the vortex finder and extends into the cyclone to reduce short-circuit flow directly from the inlet. At the conical end is the second outlet, the spigot.
Vortex to the outer wall and carried down and out the Spigot of the cone. The cleaned solution spirals up the Air Cor center via the Secondary Vortex and exits out the Vortex Finder at the top of the cleaner. In Automatic ALSI HDC ImagesMore results in images
The air core is formed at the spigot/apex as air is drawn in to the Hydrocyclone. The vortex finder provides a pathway for the air to exit the body of the Hydrocyclone. As the air flows through the vortex finder, the fluids and finer fractions are dragged along to perform the classifi ion of materials.
The next important parameter is the vortex finder. The primary function of the vortex finder is to control both the separation and the flow leaving the cyclone. Also, the vortex finder is sufficiently extended below the feed entrance to prevent short circuiting of material directly into the overflow.
Cut points can be managed by changing the inlet diameter, the vortex finder and most easily the spigot assembly. Gromatex carry a fully range of spigots and vortex finder which are available upon request.
A typical hydrocyclone consists of a conically shaped vessel, open at its apex spigot , or underflow, joined to a cylindrical section, which has a tangential feed inlet. The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe.
A Hydrocyclone can be modified to make a dry underflow while maintaining a high separation efficiency A Hydrocyclone uses an air core, which forms at the apex and extends up to the vortex finder. The formation of this air core is paramount to making a separation, and if it collapses, the separation efficiency dramatically drops.
The spigot diameter has a significant influence on performance of a hydrocyclone. In a cold model hydrocyclone dealing with fluid alytic cracking FCC alyst and water, the separation...
