  • the apparatus may comprise a first nozzle adapted to deliver a said fluid medium into the mixing zone, and an annular nozzle concentric therewith, and adapted to deliver said gaseous or vaporous medium to an annular groove adapted to act as a resonator, to impart' said sonic vibration to the gaseous or vaporous medium.
  • the annular groove may be located opposite the annular nozzle, so that the nozzle discharges gaseous or vaporous medium directly into the annular groove.
  • the apparatus may comprise a first nozzle adapted to deliver a said fluid medium into the mixing zone, and an annular nozzle concentric therewith, and adapted to deliver said gaseous or vaporous medium into the mixing zone at a supersonic velocity.

  • the apparatus of FIG. 1 has a housing 1, into which is fitted a substantially tubular center part 2, forming a conventional pressure atomizer. Pressurised liquid flows through the center conduit 3, from where it passes through tangential channels 4 into a cylindrical chamber 5, in which the liquid is given a fast rotary movement and from which it issues through the nozzle 7 in atomised fomi as a cone of spray.
  • This central pressure atomizer is combined with a generator of sonic vibrations which consists of the following components.
  • An inlet conduit 10 with annular cross-section is supplied with pressurized gas, e.g. compressed air.
  • the channel gradually tapers to form an annular nozzle 11 from which the pressurised gas flows at a high velocity directly into an annular groove 12 located on the housing opposite the nozzle outlet.
  • the dimensions of this groove are such that it resonates and sonic vibrations having a frequency of 3,000 Hz or more are imparted to the gas passing through the zone 15 between the annular groove 12 and the surface 14 which defines the front of the center part 2; the spray cone issuing from the nozzle 7 is located within the effective range of these vibrations which persist in the gas as it mixes with the atomized spray.
  • the pressurized gas and the cone of atomized spray intermix in a mixing zone constituted generally by the zone 15 and the zone radially inward thereof and extending axially a short distance from the nozzle 7. The sonic vibrations promote this mixing.
  • the device has also a housing I a pressure atomizer with parts 2 to 7 equivalent to the similarly referenced parts of FIG. 1, located therein.
  • a supply conduit 10 supplies compressed gas to an annular nozzle 11, from which the compressed gas flows via a deflecting surface 13 arranged on the center portion to an annular groove 17 located on the housing which acts as a resonator so that sonic vibrations of a frequency of 3,000 Hz or more are imparted to the gas in the zone 15.
  • a concave surface 18 reflects the sonic vibrations towards, and directs the compressed gas towards, the spray cone issuing from the nozzle 7, so that the compressed gas and the atomized spray mix under the action of the sonic vibrations in a mixing zone constituted generally by the region occupied by the spray cone.
  • sonic vibration frequency of at least 3,000 Hz
  • this does not mean that a lower frequency cannot be used.
  • the noise generation will be unacceptable for many purposes.
  • the sonic vibrations mentioned throughout this specification and claims may be ultrasonic in the sense that their frequency is above the human audio-frequency range.
  • FIGS. 3 and 4 are based on the fact that the action of sonic vibrations may also be used for intimately mixing two gases. Tl-Iis applies, for example, to the intensive intermixing of a combustible gas with combustion air.

  • a conical member 23 which reduces the flow cross-section of the center portion to a narrow annular central nozzle 24 so that the combustible gas flows at an increased velocity, corresponding to the reduction in the crosssection, substantially in the shape of a thin-walled cylinder.
  • a housing member 26 is screwed onto the center portion 21.
  • a compressed gas for example, combustion air
  • a chamber 27 at a pressure of, say, to 7 atm and flows through axially parallel bores 28 of the center portion into an annular chamber 29 which tapers to form an annular noule 30, by virtue of a conical expansion of the center portion.
  • the housing portion 26 extends beyond the front end of the center part 21 and has, facing the outlet of the annular nozzle 30, an annular groove 31 into which the nozzle 30 directly discharges the compressed gas at high velocity.
  • the groove 31 by virtue of its configuration, acts as a resonator, producing a sonic vibration field of over 3,000 Hz which propagates through gas passing through the chamber 32 and acts thereby on the compressed gas flowing from the annular nozzle 24 to promote the intensive mixing of the two gases in a mixing zone generally beyond the end of the noule 24.
  • the apparatus of FIG. 4 is of a very similar construction. It has a substantially tubular housing 41 into which leads a supply pipe 42, serving to supply a compressed gas, e.g. combustion air, at a pressure of 5 to 7 Atm.
  • a mushroom-shaped head 43 is fitted into the front end of the center portion 41 so that a shaft 44 of the head 43 forms an annular nozzle 45 with the conically tapering inner wall of the center part 41.
  • the mushroom-shaped head 43 extends beyond the end 41 of the center part and has, facing the annular nozzle 45, an annular groove 46, the dimensions of which are such that it forms a resonator for the compressed gas directed into it at high velocity and under high pressure, and produces a sound vibration of at least 3,000 Hz.
  • a housing part 47 screwed onto the center part 41 serves here for the separate supply of the second gas, e.g. a combustible gas which is introduced into a chamber 48, flows through the bores 49 and reaches an annular nozzle 50 from which it issues at high velocity in the shape of a substantially hollow cylindrical flow, reaching the zone of the sonic vibration in the gas passing through the chamber 51; the conical end face 52 of the center portion acts as a reflector for the compressed gas and the sonic vibrations directing them towards the flow of the said second gas, whereby mixing takes place generally around the mushroom-shaped head 43.
  • the second gas e.g. a combustible gas which is introduced into a chamber 48, flows through the bores 49 and reaches an annular nozzle 50 from which it issues at high velocity in the shape of a substantially hollow cylindrical flow, reaching the zone of the sonic vibration in the gas passing through the chamber 51; the conical end face 52 of the center portion acts as a reflector for the compressed gas and the sonic vibrations
  • the mushroom-shaped head 43 may be provided with a deflecting surface which directs the compressed gas towards an annular groove mounted on the center part and acting as a resonator, wherein the function is as described above with reference to FIG. 2.
  • the annular groove 31 may be replaced by a deflecting surface which deflects the flow of compressed gas towards an annular groove provided in the end face of the center portion 21 and acting as a resonator, and in which the sonic vibrations are generated.
  • the mixing of the gases may be so intensive that, where the gases to be mixed are a combustible gas on the one hand, and air on the other hand, and the mixing ratio is correctly chosen, a complete combustion without any residue can be accomplished with reliability, and with an excellent degree of efficiency.
  • the intimate intermixing of an atomized liquid with a gas is achieved when the spray cone of the atomized liquid is admixed in a mixing zone with a compressed gas issuing at a supersonic velocity from an annular nozzle mounted concentrically to the spray cone.
  • the annular nozzle for the compressed gas is a Laval-type nozzle.
  • the atomized droplets produced by the pressure atomizer pass into the mixing zone occupied by the compressed gas which is flowing at a supersonic velocity and are strongly accelerated.
  • the resulting very large frictional forces, caused by the very large differential speed between droplets and compressed gas, cause the droplets to undergo strong internal vibrations, whereby the cohesion of the droplets is overcome and these droplets disintegrate into a very fine mist.
  • the compressed gas may be both compressed air or a compressed vapor such as steam, and, where the device is to be used for atomizing combustible liquids for producing a flame, pressurized combustible gas may be used, whereby the calorific energy of the flame produced is further increased.
  • FIGS. 5 and 6 Apparatuses of this kind are shown in FIGS. 5 and 6.
  • the apparatus of FIG. 5 has a housing 61 into which is screwed a substantially tubular center part 62, into which are fitted two further parts 63 and 64. These parts form together with the center part 62 a conventional pressure atomizer.
  • the pressurized liquid flows in through a center channel 65 and passes through tangential channels 66 into a cylindrical chamber 67 in which the liquid is given a fast rotational movement and from which it issues through the nozzle 68 in the form of an atomized spray cone.
  • a supply channel 71 Arranged concentrically surrounding the atomizer 66 to 68, is a supply channel 71 having an annular cross-section formed between the housing parts 61 and 62.
  • the compressed gas is introduced into this channel at 72.
  • the channel 71 tapers to its narrowest point 73 and then expands in the form of a Laval nozzle 74.
  • the dimensions of the Laval nozzle 74 and the pressure of the supplied gas are so selected that the latter leaves the annular Laval nozzle at supersonic velocity.
  • the gas issuing at supersonic velocity acts on the droplets of the spray cone and causes a further breaking up of these droplets into particles forming a very fine mist.
  • the apparatus is preferably provided with a further nozzle.
  • FIG. 6 shows a device of this kind in axial longitudinal section, This device comprises in its center portion the entire device shown in FIG. 5, that is to say, an atomizer 66, 68, 67, which receives pressurized liquid through a center conduit 65 and a concentrically mounted annular noule 73, 74 which is supplied with compressed gas through a conduit 72 with annular cross-section.
  • an atomizer 66, 68, 67 which receives pressurized liquid through a center conduit 65 and a concentrically mounted annular noule 73, 74 which is supplied with compressed gas through a conduit 72 with annular cross-section.
  • the housing part 61 has, in this device, a further housing part 80 screwed thereto so as to form a further annular conduit 81 which is adapted to receive a gaseous pressure medium through conduits 82 provided in the housing part 62.
  • the annular conduit 81 terminates at its front end in an annular nozzle 84 directed towards radially inwardly the center, and opposite which is an annular groove 85, open towards the nozzle 84 so as to directly receive gas therefrom and arranged at the front end of the housing part 61.
  • the groove 85 acts as a resonator for the compressed gas issuing from the nozzle 84 and imparts thereto sonic vibrations which persist in the gas as it mixes with the medium issuing from the nozzle 68 or from the nozzle 74 and acting so as to promote the mixing thereof.
  • Such a multiple nozzle may be operated in many ways so that, for example, in the case of a burner nozzle for operating an industrial furnace, the following possibilities offer themselves:
  • An apparatus for mixing a plurality of gaseous streams comprising:
  • first and second independent nozzle means on said housing means concentrically disposed with respect to each other;
  • said first nozzle means including a first annular nozzle and sonic generator means located in the path of flow of said first gaseous stream from said first annular nozzle, said sonic generator means imparting a sonic vibration to said first gaseous stream as same flows therepast;
  • third nozzle means separate from said first and second nozzle means and located between said first and second nozzle means and means definin a third passageway separate from said first and secon passageway means for supplying a third gaseous stream thereto, said third nozzle means including a third annular nozzle and means for increasing the velocity of said third gaseous stream to a supersonic level from said third annular nozzle into said mixing zone.
  • said sonic generator means includes an annular grove located in the path of flow of said first gaseous stream from said first annular nozzle, said annular groove being resonant to the flow of said first gaseous stream therethrough to impart a sonic vibration to said first gaseous stream.
