Definitions

  • the present invention relates to an apparatus for the rapid mixing of two fluids, applicable in particular in water treatment for carrying out the injection and the "on-line" mixing of the water to be treated and of reagents such as, for example polymers, acids, bases, etc ... or to perform more complex operations such as coagulation.
  • reagents such as, for example polymers, acids, bases, etc ... or to perform more complex operations such as coagulation.
  • the present invention overcomes these drawbacks by making it possible in particular to produce both an instantaneous and homogeneous mixture of concentrated solutions of reagents, injected at a low flow rate relative to the flow rate of water to be treated, with a relatively low pressure drop for a gradient very important speed, this being defined by the square root of the quotient of the power dissipated in the fluid and of the product of the volume of the mixing zone by the viscosity of the fluid.
  • the apparatus according to the invention intended for effecting rapid mixing "in line" of two fluids A and B is characterized in that it comprises at least one nozzle for injecting a secondary fluid disposed in the piping in which flow / primary fluid A, the nozzle being provided with a diaphragm arranged and dimensioned so as to create, at the outlet of the nozzle, a fluid current oriented radially allowing the rapid mixing of the two fluids in a space of very small dimension .
  • the secondary fluid consists of a mixture (kA + B) of a fraction k of the primary fluid A and of the fluid B.
  • the secondary fluid consists of the only fluid B.
  • the diaphragm consists of a crown arranged around the nozzle.
  • the diaphragm consists of a plate having orifices and serving to support the nozzle
  • a pipe 1 flows, at a certain flow rate, a fluid A to which must be mixed a fluid B conveyed by a pipe 2 opening into the pipe 1.
  • the secondary fluid (B or kA + B) is introduced into a nozzle 3 disposed in the pipe 1, with a view to mixing it with the primary fluid A.
  • the nozzle 3 is provided, at its periphery, also in accordance with the invention, with a diaphragm constituted either by a crown 4 as in the example treated in FIG. 3, or by a circular plate 5 pierced with orifices 5a as shown in FIG. 4, crown and plate being arranged around the nozzle.
  • the distance d between the external surface of the nozzle of diameter D and the external edge of the crown is at least equal to 0.3 D.
  • the distance d between the external surface of the nozzle of diameter D and the edge turned towards the nozzle of the orifices that the plate has is at least equal to 0.3 D, this whatever the shape and the number of orifices 5a.
  • the radial diffusion of the secondary fluid B or kA + B in the primary fluid A is independent of the shape of the diaphragm, of the overall pressure drop of the system, of the flow rate or of the speed of flow of primary fluid A through piping 1.
  • a pipe 2 brings the fluid B to the inlet of the nozzle, the nozzle being thus traversed by the fluid B and a part k, 1 to 15% for example fluid A; the pressure drop of the assembly determining the relative flow rates of the fluids A and B through the nozzle, One obtains, under these conditions, a mixture in two phases, the first being carried out in the nozzle itself, the second, radially as described above, at the outlet of the nozzle.
  • the nozzle 3 constitutes , as shown in Fig. 2 the end of the fluid injection pipe 2 B, so that all the flow of fluid B, and only this flow, passes through the nozzle.
  • An apparatus according to the invention was used to mix reagent B at a flow rate of 75 1 / h at a stream of water A flowing in a pipe of diameter equal to 142 mm at a flow rate of 50 to 150 m 3 / h.
  • the apparatus included a nozzle with a diameter D equal to 54 mm provided with a crown-shaped diaphragm, the distance d between the outer surface of the nozzle and the outer edge of the crown, ranging from 20 to 30 mm.
  • Fluid B was mixed in fluid A in 0.05 to 0.15 seconds over a pipe length of 2 cm, with a pressure drop of 0.20 to 5 m and a speed gradient at 20 ° C from 4,000 s-1 to 35,000 s-1 .
  • the mixing was therefore carried out with remarkable rapidity, over an extremely reduced length of piping, with relatively low pressure drops for a very large speed gradient.
