Definitions

  • This invention relates to cyclone separators for separating a denser component of liquid mixture from a less dense component thereof.
  • a cyclone separator for separating a denser component of a liquid mixture from a less dense component thereof, the cyclone separator comprising at least one inlet for the admission of material to be separated and outlets for the respective discharge of the denser and less dense components, an inlet duct by which the liquid mixture, in use, is transmitted into the separator via the or each said inlet characterized in that there is further provided a heat exchanger through which a heat exchanging fluid passes, said heat exchanger positioned adjacent said inlet duct so as ⁇ jo effect heat exchange of the mixture passing through said inlet duct.
  • the cyclone separator comprises an axially extending separating chamber having towards one end the aforementioned inlet for admission of the mixture to the separating chamber, an axially positioned overflow outlet adjacent that one end defining one of the outlets.
  • the separating chamber is of generally tapered form with a relatively larger cross-sectional size at the aforementioned one end and a relatively small cross sectional size at an axially positioned underflow outlet which defines the other of the outlets at the end of the separating chamber opposite the aforementioned one end.
  • the denser component is directed to the underflow outlet in a fashion such as to encompass an inner axially positioned core of the less dense component which is subjected at least over a substantial part of its length to a pressure differential causing it to flow to the overflow outlet.
  • one of the outlets is operatively connected to the heat exchanger so that, in use, the separated component which flows from that one of the 1 outlets passes through the heat exchanger.
  • one of the outlets is
  • the underflow outlet is operatively
  • the heat exchanger and/or the auxiliary 0 heat exchanger are adapted to heat the material in the inlet 1 duct.
  • the auxiliary heat exchanger is disposed 3 upstream of the first mentioned heat exchanger with respect
  • a preferred embodiment of the invention is further 6 described with reference to the accompanying drawing, the 7 single figure of which is a diagram illustrating one form of
  • Casing 24 defines an interior
  • portion 16 connected to the end of portion 14
  • a side inlet 26 is provided for inflow
  • a heat exchange 60 is shown as comprising a coil pipe 62 wound around the duct 50 and arranged for flow therethrough of suitable heated liquid whereby to impart, by heat exchange, a raised temperature to the material passing through duct 50.
  • the separator 10 is arranged whereby one of the separated components from the separator is directed via a pipeline 66 to a further heat exchanger 68, such as in the form of the coiled pipe 70 shown as extending around duct 50.
  • a further heat exchanger 68 such as in the form of the coiled pipe 70 shown as extending around duct 50.
  • the material to be separated is passed through duct 50 and is first heated by residual heat exchange from the separated component in duct 66 which is directed through the heat exchange pipe 7 ⁇ . This effects partial heating.
  • the incoming material is further heated by use of the heat exchanger 60 before being directed into the separator 10.
  • the separator 10 otherwise operates in conventional fashion. It has been found that applying heat to oily water mixtures, for example, assists in separation of these.
  • the separator 10 may be constructed in accordance with the teachings of United States patent 4,2.37,006, 4,576,724 and 4,710,299.
  • Another example of separator which may be used is PCT/AU85/00181.
  • the component which emerges from the underflow outlet 23 or passage through pipeline 66 to heat exchanger 68 will be predominantly water whilst that emerging from the outlet 34 will be predominantly oil.
  • Separators of the kind discussed in these patent specifications are most suitable where there is a high proportion of water compared with oil, so that there will be a substantial flow through the outlet 23 as compared with the outlet 34.
  • the residual heat be recovered and applied for heating material in duct 50 be the liquid from the outlet 23 rather than from the outlet 34.
  • the separator it would of course be possible to alternatively arrange the separator so that it is the liquid from outlet 34 which is directed to the heat exchanger 68. Again, two heat exchanges may be provided so that material from both outlets can be directed to heat exchange for heating material in duct 50.
  • the described arrangement may be adapted for cooling of incoming material to be separated, by passing a coolant liquid at low temperature through heat exchanger 60.

Abstract

Le séparateur cyclone décrit, qui sert à séparer un composant plus dense d'un mélenge liquide d'un composant moins dense du même mélange, comprend au moins une entrée (26) pour l'admission du matériau à séparer et des sorties (23, 34) pour le déchargement respectif des composants plus dense et moins dense. On prévoit un conduit d'entrée (50) au moyen duquel le mélange liquide, pendant l'utilisation, est transporté dans le séparateur via l'entrée ou via chaque entrée et on prévoit en outre un échangeur de chaleur (60) à travers lequel passe un fluide d'échange thermique. L'échangeur de chaleur (60) est placé adjacent au conduit d'entrée (50), de façon à assurer l'échange thermique du mélange passant dans le conduit d'entrée. L'une des sorties (23, 34) peut être reliée de façon opérationnelle à l'échangeur de chaleur (60) ou à un échangeur de chaleur auxiliaire (68) pour permettre au fluide provenant de cette sortie de passer à travers l'échangeur de chaleur.
