✦ Synopsis


A new theory on the separation in hydrocyclones is developed on the b8ti of the dynamic behaviour of the particles to bo separated. This theory leads to the derivation of a dimensionless cyclone separation number, vzbich--as experiments have confirmed-is only dependent on the shape of the cyclone. With the aid of this number an optimum cyclone design c8n be found. Literature data on hydrocyclones prove to be in good agreement with the results of this investigation. R&urn&On expose une nouvelle thdorie sur la separation dans des hydrocyclones. Elle est basee sur le comportement dynmnique des particules qui doivent Ctre &par&es. Cette thtorie m+ne B un nombre de dparation sans dimensions pour le cyclone, qui-selon l'dvidence exp&imentale-dt!pend seulement de la forme du cyclone. A l'aide de ce nombre la forme optimale du cyclone peut &tre d&em&de. 11 s'est trouv6 que des donntes de la litt&ature sur les hydrocyclones s'accordent bien 8vec les r&ultats obtenus d8ns cette Etude. Zusammenfassung-Eine neue Tbeorie iiber die Trennung in Hydrozyklonen wird entwickelt, die auf dss dynamische Verhalten der zu trennenden Teilohen basiert ist. Sie fiihrt zur Ableitung einer dimensionslosen Zyklontrennungszahl. Versuche haben best&t@, dass diese Z&l nur von der Form des Zyklons abhiingig ist. Die optimale Form eines Zyklons liisst sich mit Hilfe dieser Zahl bestimmen. Es stellt sich heraus, dass zwischen den Literaturdaten ilber Hydrozyklonen und den Ergebnissen dieser Arbeit gute Ubereinstimmung besteht.

In a series of papers correlations are developed for the pressure drop and the separating power of hydrocyclones and rules for establishing the optimum design of hydrocyclones are derived. In the llrst two parts general considerations are given and a pressure drop correlation is ,derived. It is obt
