Definitions

  • the present invention relates to a device for increasing the homogeneity of a mixture of fluids circulating together in a pipeline.
  • mixing is meant the simultaneous presence of several fluids, miscible or immiscible.
  • the invention applies in particular to the homogenization of a mixture of water and liquid hydrocarbons flowing in a pipe; this homogenization is made necessary when it is desired to accurately measure the amount of water in the mixture.
  • the speed of the jets has a radial component which becomes less and less as one considers the jets located more and more downstream; the opposite jets no longer meet and the mixing is bad.
  • An object of the invention is to define a device for increasing the homogeneity of the mixture of two fluids, based on the same principle of fractionation of fluids into convergent jets, but which has increased performance and better job security for all the flow values of the flow considered.
  • the invention relates to a device for increasing the homogeneity of the mixture of fluids circulating together in a pipeline, by splitting the flow into multiple convergent jets, characterized in that it comprises, inserted into the pipeline a cylindrical structure comprising a cylindrical sheath inside which two plates provided with orifices define two chambers between which the flow is divided, the space between the plates being partitioned by a plurality of partitions substantially perpendicular to the axis of the sheath so as to constitute cells in which converging jets are directed coming from the orifices of the plates, said cells having openings made in the sheath for the lateral evacuation of the fluids which have mixed in the cells.
  • the plates form an angle between them between 15 and 30 degrees open downstream, so as to make the longitudinal speeds in the chambers more uniform and to improve the flow when approaching the plates.
  • the sleeve is slidably disposed in a first conduit connected to the upstream pipe, a second pipe of diameter greater than the first pipe being fixed to the latter and to the downstream pipe, the flow of the mixed fluids taking place in the area between the sheath and the internal wall of the second conduit.
  • the sheath is provided with a sliding sleeve, the displacement of which successively closes the openings of the sheath.
  • the device shown in FIG. 2 comprises an upstream conduit 10 connected by a flange 11 to an upstream pipe 12 shown partially in broken lines, and a downstream conduit 15 connected by a flange 16 to a downstream pipe 17 shown partially in broken lines.
  • the purpose of the device is to intimately mix the fluids arriving from upstream to obtain downstream a sufficiently homogeneous and stable mixture to, for example, make significant measurements of the transport concentration of one or more of the fluids transported.
  • the conduits 10 and 15 are assembled by flanges 13 and 14.
  • the device comprises a cylindrical structure arranged in the conduits 10 and 15.
  • the cylindrical structure comprises a cylindrical sheath 9 closed at its downstream end and with a diameter less than the duct 10 to accommodate it; inside the sheath are arranged two perforated plates or grids, 21 and 22, flat, provided with perforations 23; these two plates are tightly connected to the downstream bottom of the sheath and are connected to each other upstream either directly or by a deflector plate 24.
  • two chambers 25, 26 are created which separate the upstream flow in two parts. Then the fluids divide into multiple opposite jets represented by the arrows f1 in FIG. 3.
  • the two upstream chambers above and below the perforated plates can be divided by perpendicular partitions 31 and 32; these partitions contribute to maintaining the plates in the sheath 9.
  • the perforated plates deviate downstream by an angle between 15 and 30 degrees.
  • the space between the two perforated plates is divided into multiple cells 34 delimited by the perforated plates 21 and 22 and by partitions 36 perpendicular to the general axis of the sheath.
  • the jets f1 which converge towards the space 33 included between the plates, escape laterally through lateral openings 38 made in the sleeve 9. Thanks to this arrangement, the flow does not come to modify the vertical component of the speed of the jets f1 and the mixing takes place both towards the downstream zones of the device and towards the upstream zones.
  • the structure which has just been defined can slide in the conduits and in this case, which is that of the figures, its movement is provided by pistons 41 and 42 sliding in cylinders 51 and 52 arranged on either side of the duct 10.
  • the rods 61, 62 of the pistons 41, 42 pass through the flanges 13, 14 and are terminated by studs 71, 72 for fixing and guiding the sheath.
  • the sliding of the structure makes it possible to adjust the flow rate by closing one or more of the cells 34.
  • the sleeve 9 can be fixed and the adjustment of the flow rate of the mixer ensured by a sliding sleeve around the sleeve.
  • the invention applies in particular to the mixture of petroleum products circulating in a pipeline and which comprise a proportion of water which it is necessary to measure with precision. This measurement can only be made after homogenization of the mixture by passage through the device of the invention.
