Definitions

  • My'invention has for its object improvements to liquid atomizing nozzles of the type disclosed in my French Patent No. 926,438 filed on April 21,
  • nozzles that include chiefly two coaxial elongated containers preferably of a cylindro-conical shape, which containers are closed at their upper ends and are provided at their lower ends of a smaller diameter with coaxial openings located substantially in a common plane so as to define between them an annular gap, the inner container being provided at its upper end with a tangential connection through which the liquid to-be atomized is introduced substantially without any pressure while the outer container is provided also at its upper end with a tangential connection throughwhich the atomizing gas is fed under a reduced pressure, the input connections for the liquid and gas being preferably directed so as to communicate to the fluid eddying movements of opposite directions.
  • the improvements according to my invention have for their object to provide for an atomization of the liquid under the form of droplets as fine as possible.
  • the improved nozzle according to my invention is applicable advantageously to burners operating with atomized fuel and generally speaking to the atomization of any liquid.
  • the nozzle according to my invention shows among other advantages possibilities of adjusting the output in accordance with the viscosity of the liquid to be atomized and of the possibilities of adjusting within a wide range the apex angle and the length of the cone formed by the atomized liquid.
  • a further object of my invention consists in that it allows, if required, a feeding of the apparatus with the product to be atomized under a more or less high pressure, in particular when it is desired to atomize thick substancesor substances showing a substantial viscosity.
  • the improved nozzle according to my invention allows obtaining such results.
  • said nozzle includes to this purpose and along the axis of the internal chamber through which the liquid flows an Archimedean worm housed inside a cyindrical throttled part located in proximity with the output of said chamber, so as to increase the eddying movement of the liquid to be atomized.
  • the spindle carrying the Archimedean screw ends with a needle valve adapted to close to a variable extent the output nozzle for the inner chamber of the arrangement, means being provided for adjusting the position of the needle valve with reference tothe nozzle which allows for a given output an adjustment of the output speed of the liquid to be'atomized.
  • the liquid passes out of the nozzle in asubdivided form as a conical jet having a variable apex angle and energy, according to the location given to the needle valve against whichthe cone of air escaping from the output port of the outer chamber impinges.
  • the spindle carrying it may pass through the inner chamber and engage the wallet said chamber opposed to the output port, the corresponding end of the spindle carrying a thread engaging atapping in said wall.
  • a further annular chamber provided with an admission for the atomizing gas and communicating with said outer cylindro-conical capacity through a. number of channels provided tangentiallywith' referenceto the latter and distributed regularly throughout its periphery.
  • the ratio between the total cross-sectional area of the channels feeding the gas into the outer chamber and the cross sectional area of the gas at its output from the apparatus may thus be selected according to the application considered as a function of the apex angle to be obtained for the atomizin cone.
  • a still further arrangement consists in providing at the lower end of the annular chamber surrounding the outer cylindro-conical chamber or capacity receiving the atomizing gases a number of channels directed tangentially with reference to said'capacity and distributed at uniform intervals round its periphery so as to provide round the annular output port of the apparatus a secondary eddying stream of gases that is substantially at the same pressure as the stream of primary gases serving for atomization.
  • This eddying current meeting the jet of atomized liquid passing out of the apparatus increases the fineness of atom ization and ensures a spreading of the jet through a more or less open angle that varies according to the axial location of the above mentioned tangential passages With reference to the output port of the apparatus.
  • Means are advantageously provided for modifying the axial position'of said tangential passages and consequently the opening angle of the jet.
  • said passage may for instance be formed inside a movable annular member screwed into the lower part of the annular chamber sur rounding the outer cylindro-conical capacity.
  • My invention has still further for its object to allow feeding the apparatus with liquid under pressure in the case of particularly thick substances, in which case the Archimedean screw housed axially of the inner chamber through which the liquid flows may be mounted in a stationary manner so that the needle valve provided at the end of said screw may be held at a certain distance away from the output port of the machine.
  • the modifications in the output of the apparatus may be obtained through suitable variations in the feed pressure of the product to be atomized.
  • Fig. 1 is a vertical cross-section of an embodiment of the improved atomizing nozzle according to my invention.
  • Fig. 2 is a vertical cross-section of the member forming the outer wall of the chamber allowing the passage of air.
  • Fig. 3 is a horizontal cross-section of the mem-Iv -is supposed to be air.
  • Fig. 4 is a vertical cross-section of a further embodiment of the atomizing nozzle, said section passing through the channels provided at the lower end of the annular chamber distributing the atomizing gas and through the axis of the blades located underneath said passages.
  • Fig. 5 is a horizontal cross-section through line VV of Fig. 4.
  • Fig. 6 is a vertical partial cross-section of an embodiment including an Archimedean screw that is held in a stationary position.
  • the atomizing gas Obviously the gas might be a gas different from air.
  • l designates the central body of the arrangement that is axially recessed so as to form the internal chamber M for the admission of liquid to be atomized. while its'upper'part is connected to the pipe 25 feeding said liquid, which pipe does not need. in the case illustrated, to enter the chamber tangentially.
  • a member 2 arranged coaxially with said body I is also recessed axially to form the chamber 8 for the circulation of the atomizing air while the annular passage 9 provided at the lower end of said chamber allows the output of air.
  • a further hollow member 4 provided with a lateral input channel 5 for the air, said member 4 forms round the chamber 2 an annular chamber for distributing the air and communicates with the chamber 8 through passages I opening tangentially into the latter.
  • the members i2--4 are rigidly connected together through the agency of an annular flange i0 bearing on the flange 3 of the body I and screwed over the sleeve I I formed onthe member 4 while the member 2 has at its lower end a reduced diameter part engaging exactly inside the annular flange formed at the inner periphery of the member 4.
  • the flange l0 may include along its edge radial openings 12 that are regularly distributed at its periphery and wherein may be inserted suitable tools for fastening said flange over the upper edge of the collar 3.
  • Vertical bores [3 the number of which is suitably selected may be provided along the periphery of the member 4 for allowing the passage of bolts therethrough in order to secure the whole arrangement on to a suitable support that is not illustrated. '4
  • the inner chamber [4 is cylindricalin its upper part and it includes a lower conical portion I5 connected at its lower end with a cylindrical part of reduced diameterv l6 ending with a further conical or tapering part IBa.
  • a spindle l1 carrying at its lower end an Archimedean screw [8 housed inside the cylindrical part I6 of reduced diameter.
  • This spindle ends with a conical needle valve I9 adapted to close to a varying extent the output port 20 -of said inner chamber.
  • the adjustment of the needle valve as to position is ensured through a rotation of the threaded part 2
  • a knurled head 23 rigid with the spindle l1 controls the rotation of the spindle and a knurled safety nut 24 bearing against the plug 22 allows holding the spindle H at the desired height without risking any misadjustment.
  • the tangential ports 1 are arranged preferably in a manner such that the eddying movement 'mains always at least partly engaged inside said cylindrical part of reduced diameter.
  • S designates the total cross-sectional area of the air input nozzle in the chamber 8 and s the cross-sectional area for the passage of air at the output end of the apparatus, S de fines the fiow of air for a given pressure at the input end of the nozzles and the ratio S/s defines the speed of rotation of the air in the chamber 8.
  • the arrangement according to my invention will allow therefore providing, through air under a low pressure and with large adjustable crosssectional areas for the liquid, a driving action on the liquid through a suction effect and its subdivision into very fine droplets, even for large outputs and liquids of a considerable viscosity. It should be noticed that this arrangement allows producing not only a driving action on the liquid to be atomized but also a suction effect equal to several meters of water.
  • the chamber 6 ensuring the distribution of the air-is provided at its lower end with an annular opening 26 forming a passage round the lower end of the member 2.
  • Said annular passage 25 is provided with a tapping inside which is screwed a ring-shaped member 21 inside which is fitted under friction or secured in any other manner a ring 28 the bore of which is fitted with slight friction over the member 2.
  • In the lower surface of the ring 28 are provided notches 29,
  • an outer fiat ring 39 carrying radial blades 3
  • an angular shifting of the ring 30 it is possible to bring the blades 3
  • the blades direct then all or part of the eddying current of air toward the output end of the apparatus which produces thus a depression that tends to increase the spreading out of the jet of atomized liquid.
  • said spreading may reach an angle as high as Screws 42 screwed into the wall of the chamber 6 allow holding the ring 30 in a predetermined angular position and consequently the blades 31 and the ring 21 in the selected position of adjustment.
  • the apparatus is adapted to produce of its own a sufficient depression for ensuring a suction of the liquid fed without any pressure through the pipe 25.
  • the product to be atomized shows a high viscosity
