Definitions

  • the present invention relates to a device for continuously injecting, in a homogeneous manner, one or more liquid additives into a main fluid flowing in a conduit.
  • the additives are injected after a pre-dilution in a part derived from the main fluid stream.
  • FIG. 1 The best embodiment of the invention is described in FIG. 1 attached.
  • Each eductor is mounted as a bypass or "by-pass" and includes a tube (3) for admitting a liquid or semi-liquid additive (A).
  • a fluid part (F) is derived (f) by suction out of the main stream (F) and is mixed in the mixing chamber (4) with the additive injected in (3).
  • This mixture which therefore consists of the additive (A) pre-diluted in the fluid (F) is reintroduced (f) into the main stream.
  • the device according to the invention in FIG. 1 was used to evaluate the injection of a very viscous additive into a stream of cement slag.
  • the test was carried out with a marker product (CuS0 4 ) dispersed in the additive, and by recording the concentration of marker.
  • the same injection was also carried out, in a conventional manner, by a coaxial injection (that is to say injection of the additive by a coaxial conduit to the condu (1)) or by a lateral injection (i.e. - say injection through an open lateral duct in the duct (D).
  • a coaxial injection that is to say injection of the additive by a coaxial conduit to the condu (1)
  • a lateral injection i.e. - say injection through an open lateral duct in the duct (D).
  • the VIP Mixer is a rotating vortex mixer, continuously operating, disclosed in European Patent Application No. 91200440.5 has.
  • the invention is also particularly useful for the preparation of mud or drilling fluids.
  • Another particularly promising aspect of application concerns the continuous dosing of additives in separation fluids or "spacers" in the petroleum industry.
  • the invention allows for the first time to continuously vary the properties of the "spacer”, instead of varying them in stages. This results in a very significant difference in terms of the quality of the operation.
