Definitions

  • the present invention relates to spray noules and in particular to a spray nozzle in which compressed gas is used for atomizing the liquid to be sprayed and is adapted for use where large quantities of liquid are to be sprayed, and where a wide range of liquids are to be sprayed.
  • the nozzle of the present invention is designed to spray liquids at up to 160 gallons per minute.
  • prior nozzles have been satisfactory for certain applications but are not adaptable to a wide range of liquid volumes.
  • many prior arrangements do not emit a spray pattern which is acceptable for many applications.
  • a further disadvantage of prior spray nozzles is that for large liquid flow rates, high pressure air wasrequired to achieve atomization. This often necessitated the use of a more expensive air compressor.
  • the present invention is particularly applicable for use in water evaporation applications such asthe cooling of hot gas streams.
  • water evaporation applications such asthe cooling of hot gas streams.
  • it is necessary to supply a large volume of water to the gas stream in the form of a fine spray which covers a large area.
  • water evaporation is used to cool a gas stream, it is desired to achieve a certain temperature.
  • different applications require different amounts of water to be sprayed into the gas stream.
  • a nozzle which can be used in many such applications it is necessary to have a nozzle which is capable of spraying water at many flow rates while stillachieving adequate atomization of the liquid. If a nozzle is operative under many flow rates, a single nozzle design can be used for virtually all such applications.
  • liquid spray nozzles which are to be used for many applications are to allow dirty water to be sprayed.
  • water evaporation applications the water to be sprayed is not filtered and often contains particulate matter.
  • Many prior nozzles often became plugged when attempts were made to spray dirty water.
  • Other liquid spray nozzle applications also require the spraying of unpure liquid.
  • One such application is the atomization of liquids to be burned in an incinerator. This liquid may include particulate matter such as organic combustibles.
  • a spray nozzle comprising means defining a mixing chamber; means for supplying liquid to be sprayed to said mixing chamber; means for supplying a compressed gas to said mixing chamber; and means defining a smooth, substantially continuously restricting orifice for discharging a mixture of liquid and compressed gas from said mixing chamber;
  • FIG. 1 is a diagrammatic view of the circuitry employed with the present invention
  • FIG. 2 is a sectional view of the nozzle of the present invention
  • FIG. 3 is a sectional view taken on the line 33 of FIG. 2;
  • FIG. 4 is a fragmentary sectional view on an enlarged scale of a modification of the present invention.
  • FIG. 5 is a view similar to FIG. 4 showing a second modification of the present invention.
  • FIG. 6 is a fragmentary sectional view on an enlarged scale of a further modification of the present invention.
  • the present invention relates to liquid spray nozzles and in particular to a spray nozzle to be used for water evaporation applications.
  • the nozzle structure is best shown in FIG. 2.
  • the nozzle, generally indicated at 1 includes a first tubular member 10 including first and second portions 10a and 10b, respectively, and a second, concentric tubular member 12 positioned within the first tubular member.
  • the second tubular member 12 is provided with a plurality of holes 14 which provide communication between the tubular members 10 and 12.
  • a mixing chamber 16 is defined by the first tubular member 10 and the second tubular member 12.
  • annular member 18 having a plurality of passages 20 therethrough is suitably secured to the first tubular member 10 by means of bolts 22 and to the second tubular member 12 by means of a weld 23.
  • the annular member 18 serves to center the tubular member 12 within the tubular member 10 to hold the tubular member 12 in a fixed longitudinal position with respect to the first tubular member 10.
  • a conduit 25 for supplying liquid to be sprayed is connected to the second tubular member 12 and may be centered within the first tubular member 10 by means of a plate 26.
  • a conduit 28 is connected to the first tubular member 10 for supplying compressed gas to the inside of tube 10.
  • a restricting orifice 30 is mounted on the open end of the first tubular member 10 and includes a venturishaped portion 32.
  • the upstream side of the restricting orifice is tapered at an angle A and the discharge side 34 of the orifice is tapered outwardly at an angle B.
  • a head means 38 is connected to the second tubular member 12 and extends through the restricting orifice 30 as clearly shown in FIG. 2.
  • the head means includes an upstream side tapered at an angle C and an outwardly tapered portion 40 which is angled outwardly at an angle D.
  • a generally smooth radius interconnects the two tapered portions.
  • Angle A is greater than angle C and angle D is greater than angle B.
  • the restricting orifice 30 and the head means 38 define therebetween a smooth, substantially continuously restricting contour 42 which terminates in a gap G. It is essential that this contour be substantially continuously restricting and that there be no sharp shoulders on the contour. There should not be a restriction followed by an area of expansion followed by an area of further restriction. It is believed that such an arrangement would reduce the spraying capacity of the nozzle.
  • liquid is supplied from a suitable source 50 (FIG. 1) through conduit 25 by means of a pump 52 into the second tubular member 12 and through the passages 14 into the mixing chamber 16.
  • Suitable control means may be connected to the pump 52 to control the volume of liquid supplied to the nozzle 1.
  • Compressed gas is supplied from a constant volume compressor 54 through conduit 28 into the first tubular member 10, through the passages 20 in the annular member 18 and into the mixing chamber 16. The compressed gas forces the liquid through the continuously restricting contour 42 and through the gap G.
  • the air flow acts as an insulator to prevent boiling of the liquid to be sprayed when the nozzle is used in high temperature locations.
  • a single nozzle configuration may be employed for spraying liquids over a wide range of liquid flow rates. If it is desired to increase or decrease the range of liquid flow rates at which the nozzle will best function, some dimensional modifications of the nozzle will be required, but the basic nozzle configuration will remain the same. For example, a particular size nozzle will spray liquids in a range of O to 70 gallons per minute when a certain fixed volume of air under pressure is supplied to the nozzle. If it is desired to increase the flow rate range to to 160 gallons per minute, the volume of gas under pressure supplied to the nozzle must be increased in order to achieve the maximum liquid flow rate.
  • the volume of air under pressure which is supplied to the nozzle of this invention is determined by the desired maximum liquid flow rate. That same volume of air will, of course, provide good spraying of the lesser liquid flow rate.
  • the size of the passages 20 in the annular member 18 is increased.
  • the size of the gap G must also be increased.
  • the size of the gap G can be adjusted in the factory by longitudinally adjusting the position of the tubular member 12 with respect to the tubular member 10. Such adjustment varies the position of head means 38 with respect to the restriction 30. For example, if it is desired to increase the size of the gap G, as viewed in FIG. 2, the tubular member 12 is moved to the right with respect to the tubular member 10. Once the desired gap size has been reached, the weld 23 is made. The second portion 10b of the first tubular member is then secured to the first portion by means of bolts 22. The nozzle is then permanently adjusted for a desired flow rate range.
  • the spray nozzle can be made adjustable. Examples of adjustable arrangements are shown in FIGS. 4 and 5. In FIG. 4 adjustment is accomplished by providing a threaded connection between the second tubular member 12 and the annular plate 18. If it is desired to vary the size of gap G, it is only necessary to screw the member 12 through the annular member 18. Since the annular member 18 is fixed to the tubular member 10 by means of the bolts 22, there will be an adjustment between the head member 38 and the restriction 30. In FIG.
  • the adjustment is accomplished by welding the annular member 18 to the tubular member 12 and providing a plurality of shims or washers 60 between the flange 19 on the annular member 18 and a plate 61 which the tubular member 10 is secured. If it is desired to widen the gap G, one or more of the washers 60 is removed. When the bolts 22 are tightened, the tubular member 10 and hence the restriction 30 are moved relative to the tubular member 12 and, the gap G is widened. If it is desired to narrow the gap G, additional washers 60 are added and relative movement takes place between the valve member 38 and the restriction 30 to narrow the gap G.
  • angles A to D can be varied.
  • angle A should be greater than angle C and angle D must be greater than angle B so that there is a continuously restricting contour.
  • angles B and D are smaller as shown in FIG. 6, it is believed that a nozzle suitable for low liquid flow rates is achieved.
  • the wider angle shown in FIG. 2 is more suited for the high flow rates desired for water evaporation nozzles.
  • the nozzle of FIG. 6 is believed to be more desirable for the low flow rates associated with an incinerator application.
  • a nozzle structure which is adjustable and adaptable to a wide range of flow rates has been provided. Excellent atomization of the liquid being sprayed is achieved. The continuously restricting contour of the nozzle assures proper atomization and liquid flow. Large quantities of water can be sprayed. The nozzle has been successfully tested at liquid flow rates of up to gallons per minute. Because of the relatively wide gap, the nozzle of the present invention is capable of spraying liquid which contains particulate matter.
  • a spray nozzle comprising:
  • a second tubular member mounted within said first tubular member and having at least one aperture therein for providing communication between said first tubular member and said second tubular member;
  • said restricting orifice and said head means defining a smooth, substantially continuously restricting contour which terminates in a gap;
  • the spray nozzle of claim 2 further comprising means for centering said second tubular member within said first tubular member; said centering means including at least one opening therethrough for the passage of compressed gas.
  • centering means includes an annular member fixedly secured to said first tubular member and threadedly secured to said second tubular member to thereby define means for adjusting said second tubular member.
  • centering means includes an annular member fixedly secured to said second tubular member and adjustably secured to said first tubular member to thereby define means for adjusting said second tubular member.
  • a spray nozzle capable of spraying liquids containing particulate matter comprising:
  • a first tubular member having a venturi-shapedrestricting orifice at one end thereof and adapted to be connected to a source of compressed gas
  • a second tubular member mounted within said first tubular member and having at least one aperture therein and adapted to be connected to a source of liquid to be sprayed;
  • said first and second tubular members defining a mixing chamber upstream of said restricting orifice and liquid supplied to said second tubular member is supplied to said mixing chamber directly through said aperture;
  • said restricting orifice and said head means defining from said mixing chamber a smooth, continuously restricting contour which terminates in a gap whereby liquid is adapted to mix with compressed gas in said mixing chamber and the mixture is discharged from said mixing chamber through said gap.
