Abstract

A fluid dispersion nozzle and system for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the fluid dispersion nozzle receives pressurized and fluid from fluid dispersion machinery, aerosolizes the fluid into near-monodispersed droplets, and distributes the aerosolized, near-monodispersed droplets evenly over long distances. The nozzle is an adjustable, dual-contour, supersonic nozzle that includes a main adjustable contour, an auxiliary contour, an axial fluid injector, a resonator, and a plunger.

Claims

1. A fluid dispersion nozzle comprising:

a nozzle body;

a hollow tip of the nozzle body centered within the nozzle body;

at least one contour enabled to adjust airflow;

an axial fluid injector surrounded by the at least one contour and enabled to adjust fluid flow; and

a resonator and a plunger for aerosolizing the fluid;

wherein;

the hollow tip of the nozzle body connects to a fluid injector body and a nose cone;

the resonator attaches to the fluid injector body via a first screw; and

the plunger attaches to the fluid injector body via a second screw.

2. The fluid dispersion nozzle of claim 1, where the fluid dispersion nozzle is a supersonic, adjustable, dual-contour nozzle.

3. The fluid dispersion nozzle of claim 1, wherein the fluid dispersion nozzle is connected to fluid dispersion machinery.

4. The fluid dispersion nozzle of claim 3, wherein the fluid dispersion machinery is comprised of an air compressor and a fluid pump.

5. The fluid dispersion nozzle of claim 1, wherein the at least one adjustable contour is comprised of a main adjustable contour and an auxiliary adjustable contour.

6. The fluid dispersion nozzle of claim 5, wherein:

the main adjustable contour is positioned within the nozzle body and around the nose cone, and

the auxiliary adjustable contour is positioned within the nose cone and around at least a portion of the axial fluid injector and at least a portion of the fluid injector body.

7. The fluid dispersion nozzle of claim 6, wherein the main adjustable contour and the auxiliary adjustable contour have adjustable cross-sections.

8. The fluid dispersion nozzle of claim 1, wherein the hollow tip of the nozzle body contains the axial fluid injector.

9. The fluid dispersion nozzle of claim 8, wherein the hollow tip of the nozzle body connects to the nose cone via a spacer.

10. The fluid dispersion nozzle of claim 1, wherein the first screw and the second screw are the same screw.

11. The fluid dispersion nozzle of claim 1, further comprising:

a fluid pump to transfer fluid from a fluid tank, through a pressure-regulating valve and hollow pylon and into the hollow tip of the nozzle body, wherein the pressure-regulating valve maintains the fluid pressure consistency of a predetermined rate;

a saddle that interfaces with the plunger;

a spring that pushes a steel ball toward an outer wall of the resonator, wherein the resonator has at least one axial slot and the steel ball engages with the at least one axial slot to lock the plunger in a specific position relative to the resonator;

a disperser body;

a nozzle head held in place by a clamping screw; and

wherein the disperser body and the nozzle head define at least a portion of an outer part of the fluid dispersion nozzle.

12. A method of fluid dispersion, the method comprising:

pumping pressurized air from an air compressor into a fluid dispersion nozzle;

pumping fluid through a fluid pump and into the fluid dispersion nozzle;

combining the air and the fluid in the nozzle to create a near-monodisperse cloud; and

distributing the near-monodisperse cloud into atmospheric air;

wherein;

the air flows from the air compressor, into the nozzle, and through an auxiliary contour and a main adjustable contour;

the fluid flows from the fluid pump through a pressure regulating valve, through a hollow pylon connected on a first end to the pressure regulating valve and on a second end to a hollow tip of the nozzle body, and into the hollow tip of the nozzle body;

the fluid flows forward from the hollow tip of the nozzle body through an axial fluid injector and a fluid injector body until it hits a plunger;

the fluid reflects off the plunger and out through a hole in a side of the fluid injector body;

the air flowing through the auxiliary contour forces the plunger reflected fluid forward and into contact with a resonator;

the plunger reflected fluid reflects off the resonator and back toward the auxiliary contour and the main adjustable contour;

the air flowing through the main adjustable contour forces the resonator reflected fluid forward past an end of the nozzle and into the atmospheric air as the near-monodisperse cloud.
