Definitions

  • a process and device for the mechanical formation of aerosols are disclosed. whereby the formation of a downwardly flowing liquid film is effected on the slanted sur face of a downwardly widening mouthpiece of an air supply line, which mouthpiece points downwards and the breakup of the film at an annular edge of the mouthpiece by an airstream which escapes under slight excess pressure from the interior of the at least approximately cone-shaped hollow space inside the mouthpiece, whereby the film is atomized m the form of an essentially vertically downwardly directed spray cone
  • a limiting body may be inserted in the mouthpiece to direct the airstream essentially entirely toward the interrupting edge 01 the mouthpiece.
  • the invention concerns a process for the mechanical spraying of liquids, preferably with aerosol formation, as well as a device required for carrying out this process.
  • liquid as used in this invention means solutions and emulsions as well as suspension
  • aerosol means primarily mists which are produced by atomizing solutions or emulsions in the air.
  • spraying liquors for the production of aerosols are sprayed from nozzles, e.g. of the venturi type. It has also been suggested to produce aerosols by spraying the liquid to be sprayed, from a nozzle onto one side of a flat wall terminating an air pipe, while the air stream coming out of the pipe escapes through a vent which forms a U- or horseshoe-shaped terminal edge with the wall and thus the liquid film flowing down over the wall is broken off and atomized.
  • the flat sur face of the wall together with the shape of the vent thus formed, however, cause the liquid to be sprayed in a cloud whose drift is completely dependent upon the prevailing direction of the wind.
  • an atomization of the liquid e.g. a spraying liquor
  • the new device in contrast to the last-described known device, to direct the atomized cone substantially vertically or as desired, at a slight angle to the vertical towards a surface to be sprayed, e.g. a planted field.
  • Due to the special form of the spraying device it is possible, by means of the spray cone which is directed substantially perpendicular to the field, to appreciably prevent a drifting of the sprayed material, even with a strong side wind.
  • the process according to the invention comprises the mechanical formation of aerosols, preferably for the treatment of agricultural plantations, and comprises producing a downwardly flowing liquid film on a slanted surface of ringshaped, downwardly widening cross section, and breaking up said film at an annular interrupting edge of said surface which edge is substantially horizontally situated, by an air stream which is escaping under slight excess pressure from the interior of the at least approximately cone-shaped hollow space formed by the liquid film, whereby the latter is atomized, while forming an essentially vertical, downwardly directed spray cone.
  • the liquid film can be of annular, elliptical or similar ringshaped, e.g. an elongated ring-shaped or race-track (Z) cross section.
  • an air stream is preferably employed which has a pressure of at least 0.l, preferably however about 0.4 atmosphere of excess pressure,
  • a particular feature of a preferred embodiment of the process according to the invention comprise so directing the air stream in the interior of the said hollow space that it forms a mantle of correspondingly shaped cross section, e.g. instead of a solid cone, a cone mantle of variable thickness, in the side and upper portion of the said hollow space.
  • the exit velocity of the air stream can be varied so that the particle size of the liquid to be sprayed as well as the degree to which the resulting spray cone is filled with the mist formed can be adjusted as desired.
  • the device according to the invention for the application of the above-described process has an air supply line having a downwardly widening mouthpiece pointing downwards and preferably of ring-shaped, or of elliptical, or of elongated ringshaped cross section, as well as a liquid supply line having one or a plurality of downwardly directed outlet orifices, which liquid supply line is mounted on the outer wall of the mouthpiece encircling the latter in a substantially horizontal plane.
  • the liquid e.g.
  • a spray liquor flowing downward on the outer wall of the mouthpiece below the said outlet orifice or orifices contacts the air stream escaping from the mouthpiece at the lower terminal edge thereof and is atomized thereby in the form of droplets in a spray cone having the main axis thereof directed substantially vertically downward.
  • a crown like ridge of teeth or the like projections is mounted on the outer wall of the mouthpiece between, on the one hand, the plane in which the said outlet orifices are located and, on the other hand, the lower terminal edge of the mouthpiece in an intermediary plane extending parallel to the terminal edge, said ridge preferably extending in the direction of the intermediary plane.
  • the above-mentioned preferred embodiment of the process according to the invention is attained, e.g., by mounting a limiting body which conforms in shape to the said mouthpiece, inserted into the mouthpiece from below and preferably arranged coaxially with the latter, the outer wall of which limiting body preferably extends parallel to the inner wall of the mouthpiece; the interval between the limiting body and the inner wall of the mouthpiece can be adjusted by raising or lowering the limiting body along the common axis.
  • the liquid supply line mounted around the mouthpiece is provided at its lowest point, preferably directly above the part of the outer wall of the mouthpiece next adjoining the supply line downstream, with a continuous outlet aperture having an adjustable cross section.
  • a valve regulator not shown in the drawings, in the inlet pipe to the liquid supply line.
  • an excess pressure of 0.4 atmospheres and a compressed-air consumption of about 1,000 m per hour is used, and a device according to the invention is employed which preferably has a mouthpiece with an aperture angle of about and the limiting piece which extends into the mouthpiece has an aperture angle of about l20-140, while the height of the mouthpiece (height of the cone frustum) is about 40-50 mm.
  • the device is preferably so adjusted that the interval between the lower edge of the mouthpiece and the other wall of the limiting piece is such that the latter protrudes somewhat beyond the outer edge of the mouthpiece.

  • the inner cone frustum 6 can now be raised or lowered in respect to the outer mantle 1 so that the cross-sectional area of the cone mantleshaped air channel formed between the mantles 1 and 6 is increased or decreased.
  • the velocity of the airstream flowing out of the compressed-air pipe 3 via the feed pipe 2 through the said channel in the direction of the arrow is decreased or increased, and depending on the distance and the relatively higher or lower position of the lower edge 6a or 60 of the inner cone mantle 6 in respect to the front edge la of the outer cone mantle 1, the density and the mean downward direction of the airstream when leaving the said channel are also varied.
  • the liquid to be sprayed e.g. a spraying liquor for agricul tural purposes, is supplied to the outer wall of the cone 1 out of a main supply pipe 9 via one or a plurality of branch pipes 10 and a ring-shaped distributing pipe 11, which is endless or optionally divided into segments, and provided on the lower side thereof with orifices 12.
