Hydrocyclone Liquidfiltration Brochure

HYDROCYCLONE- COMPACT ROBUST SEPARATOR- NO MOVING PARTS, NO CONTROL- EASY TO INSTALL- HIGH EFFICIENCY- LOW INVESTMENTWorking principle:The hydrocyclone is built out of a cylindrical upper partwith a top outlet in the middle and a tangential side inlet.The top part is connected to a conical bottom part withexchangeable drain part Dirty water is pumped under a constant pressure into thetangential inlet (1) and will be accelerated, as the primaryvortex (2), into a spiral rotation towards the apex (7)which is connected to the cylinder in the middle and willproduce a throttling effect. This effect will cause a secon-dary vortex down the conical shape to the drain, a conewith open apex (7). The centrifugal forces drive the parti-cles with a specific gravity of more than 1.2 g to the outsi-de of the spiral flow and push them together under anincreasing velocity of up to several thousands of “G” for-ces down to the drain cone outlet. In the middle of thestream a vortex tracker (5) is created with low pressure.Where there is high pressure at the outside of the stre-am. The low pressure water, without heavy particles, willleave the hydrocyclone via the vortex tracker (5) and theopen apex overflow (6) at the top of the cyclone. Theconcentrated (8) heavy particles with a small water flow,less than 1% of the inlet flow, leave the hydrocyclonethrough the cone with small open apex (7) in the bottom.The efficiency of the cyclone and the size of the particlesthat will be removed is related to the diameter of theupper cylinder, the diameter of the drain outlet and thecounter pressure of the open top outlet. By changingthese parameter one can influence the separator efficien-cy. Efficiencies of up to 98% can be reached.The energy consumption of the cyclone is the pressureloss in the housing by acceleration of the flow. Averagethis is 1-1.5 bar for a cyclone of 5 cm diameter.At 2.5 bar inlet pressure the top outlet pressure is about 1bar at the top of the cyclone. Particle size removal can befrom 5 < d < 80 micron with a concentration up to 1 gr/ldepending on size distribution and specific gravity. Fieldtest are the best way to find out if a hydrocyclone is theproper technology for solving the filterproblem.HYDROCYCLONE (CENTRIFUGAL SEPARATOR)Short Explanation:Hydrocyclones are simple, robust and selfcleaning separators that can separate fine par-ticles with relative high concentrations under centrifugal forces without the use of amotor.Cyclon 28 Cyclon 55 Cyclon 110 Cyclon 500Cyclon 28 Cyclon 55 Cyclon 110 Cyclon 500A B C D E FCyclon 28 235 23,5 7 38 42 18Cyclon 55 470 79,5 18,5 97,5 77 18Cyclon 110 550 81 28 120 116 35Cyclon 500 1025 52 41 150 174 47Technical specifications:Type Flow rate Max. operating Clean waterLitre/minute Pressure Pressure MaterialCyclon- 28 28 2.5 Bar 0.5 Bar PolyurethaneCyclon- 55 55 2.5 Bar 0.5 Bar PolyurethaneCyclon-110 110 2.5 Bar 0.5 Bar Polyurethane & SSvortexCyclon-500 500 2.5 Bar 0.5 Bar Steel withpolyamide coatingFor higher flow demand, the cyclones can be mounted on manifolds in a circular formor next to each other on a central headerAdvantages of the hydrocyclone are :- no moving parts- no consumption or blocking of filter elements- high efficiency- no electric or pneumatic control necessary- low service demand- easy to install- simple construction, compact- low investmentImportant for installation;* Keep a constant pumppressure* Prefiltration of 1mm in order to prevent blocking* Use a long elbow on top outlet, no knee because this will clog* Keep a constant flowV&T GROUP BVPOSTBUS 70893286 ZH Klaaswaaltel : 0186 574151*Fax : 0186 573722E-mail : info@v-tfiltergroup.comhttp//:www.v-tfiltergroup.comFiber Filtration BVEinsteinstraat 83281NJ Numansdorptel :0186 574151*fax :0186 573722E-mail :info@fiber filtration.comhttp//:www.fiberfiltration.com
