Definitions

  • ABSTRACT A nozzle for finely dispersing a liquid in a gas stream, usually air or steam, has therein a reverberation chamber for producing acoustic energy in the gas stream.
  • the gas then flows through a plurality of tubular passages which are intersected by tubular passages carry-' ing therethrough a liquid to be nebulized, said liquid usually being oil.
  • the nozzle is particularly useful for nebulizing oil in preparation for combustion thereof.
  • a high efficiency of dispersion of a liquid is obtained by the use of a nozzle having a resonant chamber therein from which the gas flows through a plurality of tubular passages to the exterior of the nozzle. Simultaneously, oil flows through a plurality of tubular passages equal in number to those carrying the gas stream to the exterior of the nozzle, each of the oil passages intersecting one of the gas passages proximate the surface of the nozzle. The energy of the gas stream atomizes the flowing liquid into fine droplets.
  • an axial stem is disposed centrally within the resonance chamber, modifying the resonant chamber into an annulus for the purpose of increasing the efficiency of energy transfer by the resonant chamber.
  • an object of the present invention is to provide an improved nozzle for atomizing a liquid stream by means of a gas stream.
  • Another object of the present invention is to provide an improved nozzle for generating acoustic energy within a gas stream to be used for atomizing a liquid.
  • FIG. 1 is an end view of a nozzle in accordance with the present invention
  • FIG. 2 is a cross-sectional view taken along the line 2-2 of FIG. 1;
  • FIG. 3 is a cross-sectional view taken along the line 33 of FIG. 2;
  • FIG. 4 is a cross-sectional view of another embodiment of the present invention.
  • a nozzle in accordance with the present invention is generally indicated by the reference numeralll.
  • nozzle 11 which is usually air or steam, is brought to nozzle 11 through inner tube 12.
  • nozzle 11 is joined to the inner tube 12 by threaded section 13.
  • Nozzle 11 is positioned axially with respect to inner tube 12 by seating of end 14 on shoulder 15.
  • Gas flowing at high rate through inner tube 12 reaches resonant chamber 20 in which part of the energy of flow is converted into acoustic energy.
  • Chamber 20 terminates in an end 16. The gas carrying the acoustic energy departs resonant chamber 20 through tubular passages 17.
  • the liquid to be dispersed usually oil
  • annular passage 18 defined by outer tube 19 and inner tube 12.
  • the flowing oil on leaving annulus l8 enters tubular passages 21 which intersect gas passages 17 proximate surface 22 of nozzle 11. Atomization of the flowing liquid takes place at the intersection between the plurality of passages 17 and 21 at high efficiency.
  • outer tube 19 is connected gas-tightly with nozzle 11 by the use of gasket 23.
  • Axial location of nozzle 11 with respect to outer tube 19 results from seating of shoulder 24 on end 26 of outer tube 19.
  • nozzle 11 is provided with flats 27.
  • stem 28 is centrally disposed within passageway 29 leading to resonant chamber 20.
  • Chamber 20 terminates in an end 16.
  • Stem 28 has a flange 31 which is held between end 32 of inner tube 12 and shoulder 33 of nozzle 11. Ducts 34 in flange 31 provide for the flow of gas from inner tube 12 to resonant chamber 20.
  • Upper end 36 of stem 28 seats within aperture 37 provided in nozzle 11.
  • the purpose of the stem 28 is to increase the efficiency of resonant chamber 20 in producing acoustic energy in the gas flowing therethrough. Where it is desired to use the nozzle of FIG. 4 without stem 28, the embodiment of FIG. 2 results.
  • An acoustic nozzle having a downstream exit end and an upstream inlet end comprising a central passage extending between said inlet and exit ends for receiving gas supplied at said inlet end, a resonant chamber communicating with said central passage and located adjacent said exit end, a plurality of exit passages extending between said central passage and the exterior of said nozzle to deliver gas outwardly of said nozzle at acoustic energies from said central passage, said exit passages communicating with said central passage upstream of the end of said resonant chamber, and a plurality of fuel passages within said nozzle for receiving fuel to be nebulized, said fuel passages having inlet and outlet ends, said outlet ends communicating with said exit passages intermediate the ends thereof.
