Definitions
- the object of the present invention is a device and method of atomization or nebulization of a liquid by means of the use of a driving gas or vapor (hereinafter, gas) which is introduced under pressure in said device. Both fluids are expelled outside after mixing, producing the liquid in the form of an aerosol or droplet suspension carried by the gas stream.
- the device consists of a liquid storage chamber, contained in a pressurized container or bottle, and a region of liquid-gas mixing where the combination between the two phases mentioned and the exit to the outside takes place.
- the supply gas penetrates into the bottle through an injection nozzle, subsequently leaving said container through the mixing region.
- the free surface of the liquid inside the bottle is pressed by the supply gas, whereby the liquid is propelled into the mixing region through a feed tube whose suction mouth is close to the bottom of the bottle.
- the other end of the feeding tube called the nebulizer end, has an outlet hole.
- Said outlet section is approximately faced with an outlet opening of the container through which the gas / liquid mixture in the form of a suspension of drops is exited.
- Said exit hole is perforated in the wall of the container.
- a central aspect of the invention is that the inner edges of said exit hole and the outer edges of said exit hole define two closed lines in approximately parallel planes and spaced apart from each other in a short separation interval; the passage surface between both edge lines is ring-shaped.
- SUBSTITUTE SHEET (RULE 26) precisely in said annular section; said minimum section has a surface area of the same order as the section of said exit hole.
- the feed tube can have a pressure loss regulator that allows to regulate the flow of atomized liquid.
- Nebulizer devices allow the transformation of a liquid preparation into an aerosol or micro-droplet suspension.
- Nebulizer devices usually consist of a reserve chamber where the liquid is introduced, a fogging chamber where the aerosol is generated, and a source of energy, usually a pump, to propel the carrier air from the suspension.
- Aerosols have been used in numerous technological fields, in particular as a means to treat airway diseases by nebulizing liquid medications.
- the administration of aerosolized drugs by inhalation allows adequate concentrations of medications to be obtained in the respiratory system while minimizing side effects.
- the applications in the agronomic sector are well known, for spraying pesticides, for example in disinsection treatments.
- Manual or automatic equipment is used for this purpose, which allows a targeted application and some ability to regulate the thickness of the drop, whose diameter usually varies between 100 and 500 microns.
- the term nebulization is usually used: in insecticide applications, this increases the buoyancy of the preparation as well as the covered extension when the deposition of the drops occurs.
- the liquid is driven through a narrow nozzle;
- the dynamics of the flow in said nozzle determines the size of drops, hence the malfunction when the liquid used causes abrasion in the nozzle or when settling occurs that alter the geometry of the ejection.
- Most industrial applications are based on this principle: humidification of enclosed spaces, micro-irrigation, surface treatment in steel and sheet manufacturing, paint application.
- pneumatic atomization A second fluid, usually a gas, is used to facilitate the atomization of the liquid.
- the shear stresses between the gas and the liquid cause its disintegration in drops.
- the pneumatic atomization in general, achieves good yields with a moderate pressure.
- pharmaceutical inhalers stand out.
- the inhalers usually consist of a chamber that contains the medicine in liquid form, an air jet, a feeding tube for the medicine, and an impaction plate combined with a deflector Compressed air is injected, creating a Venturi effect when circulating at high speed through a narrowing.
- the liquid fragments into drops of varying size collide with the deflector and return to the chamber, while the smaller ones are dragged by the air flow and go outside.
- the discharge gases can be CFCs (chlorofluorocarbon-two), with the consequent environmental uncertainties.
- Electro-hydrodynamic atomization of liquids (electrospray): it is a fundamental tool of biochemical analysis (Electrospray Mass
- FF Flow Focusing
- WO 0076673 proposed a flow configuration, then called "violent flow focusing"; unlike FF, the focusing gas here has an essentially radial and centripetal flow (diaphragm flow), concentrically directed in a thin layer that intercepts the liquid outlet on a flow surface transverse to the axis of movement of the liquid.
- the gas comes from a pressure chamber, and the intense interaction that occurs between the liquid phase, whose movement is essentially axial, and the gaseous phase, directed radially, results in an immediate transfer of quantity of movement.
- the liquid exits into the outer atmosphere in the form of a jet.
- the invention described herein introduces design concretions that allow the complete atomization of the liquid jet before its exit to the outside, while ensuring a remarkable simplification of design, not being necessary more than a single pressurization element.
- the present invention belonging to the field of pneumatic atomizers, aims to combine the advantages of a simple and robust design, with continuous operation at low pressures and by means of an impeller gas which, in most cases, can be atmospheric air . Because the present invention makes it possible to use mass flow rates of gas against liquid as low as one part of gas per seven parts of liquid, maintaining an adequate level of liquid atomization, the device object of the present invention is energetically very bright .
- the low energy consumption of the device described here is compatible with a renewable energy source: a photovoltaic cell or a wind generator, for example.
- the device operates with three flow rates depending on the position of a three-way valve. This valve is also superfluous with the present invention.
- Figure 1 General scheme of the AFF device with joint pressurization.
- the gas (G) is introduced into the pressurized container (2) through the nozzle (5).
- the gas pressure drives the liquid (L) contained in the storage chamber (1) and takes it through the tube (6) to the mixing region (4) where it interacts with the gas forming an aerosol that goes outside through the exit hole (3).
- Figure 1 (bottom detail): Essential geometry of the invention in the mixing zone (4) including the liquid and gas inlets, the outlet of the mixture and the edges 10 and 11.
- the liquid stream is intercepted radially perimetrically. It is therefore a perimeter cross flow in which a diaphragm flow strangles a liquid jet.
- Figure 2 Scheme of a manufactured device.
- gas (G) enters a plastic bottle (17) through the opening (19) and drives the liquid (L) contained in the storage chamber (1) to the mixing zone through the feed tube (24) first and the capillary tube (22) later.
- the liquid interacts with the gas forming the aerosol that goes outside through the hole in the plate (21).
- the detail (*) shows the mixing zone as described in figure 1.
- Figure 3 Diagram of a device with two chambers and exhaust valve.
- the gas enters the container (2) through the nozzle (5) and pressurizes the upper (13) and lower chambers (14) at pressures p 0A and p oB .
- the values taken by these pressures are determined by the pressure drops that the gas undergoes through the connection port (15) and the exhaust valve (16).
- the pressure in the lower chamber pushes the liquid through the tube (6) to the mixing zone (4) where it interacts with the gas and forms the aerosol that goes outside through of the outlet hole (3).
- FIG. 26 Scheme of a device with three cameras. It is analogous to the device described with the previous figure, but the upper compartment is in turn subdivided into two enclosures (13a and 13b), separated from each other by a second connection port (15a). The loss of load associated with said second port allows the pressure (p oc ) in the upper chamber to be adjusted and, therefore, the pressure (p t ) in the mixing zone (4).
- Figure 5 Particular configuration in which the outer walls of the hole form an angle ⁇ with the axis thereof.
- Figure 6 Diagram of a device characterized in that the joint pressurization chamber in which the liquid and gas are located consists of two removable parts (27, 28), the liquid being completely contained in one of them (28).
- the gas is introduced through the nozzle (5) and drives the liquid from the liquid storage chamber (1) to the mixing zone (4) through the transport tube (29).
- Figure 7 Device scheme with external vaporizer.
- the vaporizable liquid (L v ) contained in the vaporizable liquid chamber (30) is heated by means of a heat (Q) -
- the generated steam (V) is conducted to the nozzle (5) and enters the inside of the bottle (2).
- Said vapor is used for the delivery of the atomizable liquid (L 3 ) to the mixing head (31) where it is mixed with the vapor forming the aerosol.
- Figure 8 Diagram of device with joint vaporizer.
- the heat provided (Q) is used on the one hand to heat the liquid destined to vaporize (L v ) and act as a discharge steam (V) and, at the same time, to heat the liquid destined to be atomized (L 3 ).
- the discharge steam and the driven liquid reach the mixing head (31) and are mixed forming the aerosol.
- said atomizable liquid (LJ is in solid phase before being heated.

- AFF Anti Flow Focusing
- any fluid that is sufficiently different from the dispersed phase eg immiscible
- said carrier phase will be air or some inert gas, so, to simplify the description of the invention, hereinafter we will refer to it simply as "gas", without implying any type of restriction in the range of fluids that can be used as a carrier phase.
- the liquid is taken to the area where the interaction with the gas takes place by means of a hermetic transport that prevents premature mixing between the two phases.
- the form of this liquid transport means can vary substantially without limiting the operation of the AFF, the form of the exit thereof being only somewhat influential as it is in the area where the interaction between both phases occurs.
- this means of transport hereinafter we will refer to this means of transport as a "tube”, without implying any restriction on the shape, number or configuration of the parts that make up this means of transport.
- SUBSTITUTE SHEET (RULE 26)
- AFF AFF
- a liquid that circulates through a feed tube (6) with a certain flow rate enters through the outlet hole (9) of said tube to a pressurized chamber that is continuously filled with a gas .
- Said pressurized chamber has an outlet (3) through which the mixture of the carrier and dispersed phases comes out.
- This hole must be located in front of the outlet hole (9) of the liquid tube and next to it, with a short axial offset between the opposite edges of said hole and said hole defining a passage section for the gas. The interaction between both phases occurs in the mixing region located between said hole and said hole.
- the gas that, due to its pressure, seeks to exit to the outside environment, must previously cross said passage section defined by the annular interval between the opposite edges of said hole and said exit hole; this fact gives the gas flow an essentially radial orientation and perpendicular to the axis of movement of the liquid at its exit from the tube; this gas movement, which centripetally intercepts the flow of liquid, is called ⁇ -diaphragm; the minimum passage section for the gas in its movement through said thin layer must have a surface substantially equivalent to the passage surface of the outlet orifice (3).
- This geometric configuration causes the gas that floods the pressurized chamber to undergo a strong acceleration (abruptly changing both speed and direction) when reaching the exit hole of the tube and encountering the axial flow of liquid coming out of said tube.
- the liquid that flows from the tube undergoes a violent implosion as a result of the intense radial and centripetal component of the gas with which it is interacting.
- This generates in the liquid in the outlet section of the tube a central overpressure zone and, at the same time, a depression zone near the inner edge of the tube outlet.
- a pattern of vorticity is generated in the liquid that produces the appearance of violent non-stationary turbulent movements in the exit zone of the liquid from the tube.
- SUBSTITUTE SHEET (RULE 26) Drop size generated depends fundamentally on: (a) the pressure p 0 of the carrier gas within the pressurized chamber at sufficiently large distances from the outlet orifice thereof; (b) the flow of liquid that flows from the tube; (c) the particular geometry of the device in the vicinity of the hole (outer shape of the tube, treatment of the surfaces adjacent to said hole and said exit hole, diameter thereof, etc.) and (c) the geometry of the edges of the hole and the hole of the tube.
- the carrier gas that floods the pressurized chamber undergoes a pressure drop from said chamber (p 0 ) to the pressure in the outdoor environment (pj; the gas reaches the ambient pressure just in the outlet section of the orifice outlet (3) of the chamber
- the gas pressure (P 1 ) is higher, but close to the outside, if the outlet of the liquid tube is located sufficiently close to the exit hole of the chamber (which necessarily occurs if the gas passage section described above between the tube and the hole is equivalent to the section of the exit hole), the gas pressure at the outlet of the tube of the liquid will be lower than the gas pressure of the pressurized chamber in areas far enough from the hole, so if the liquid comes from a container communicated with the pressurized chamber (in accordance with the principle of presu ⁇ z ⁇ ation conju nta), there is a pressure difference between the free surface of the liquid in the container that contains it (p 0 , pressure of the pressurized chamber) and the outlet of the liquid tube (p
- the liquid flow rate is controlled by three parameters: (a) the distance between the edge of the tube and the joint outlet orifice of the mixture, which controls the said minimum passage section for the diaphragm flow, (b) the pressure difference caused by the difference in height between the free liquid surface of the vessel and the tube outlet (in
- SUBSTITUTE SHEET (RULE 26) sufficiently small devices the influence of this parameter is negligible); and (c) the pressure drop caused by the pressure losses generated in the transport of the liquid from the container to the exit of the tube. It is easier to control this third parameter since the first one requires modifying the geometry of the device, and the second one varies with time (the height of the free surface decreases with the consumption of liquid). Through the interposition of localized load losses, the flow of liquid and, therefore, the characteristics of the aerosol obtained can be precisely controlled.
- the method described here has proven to be extremely effective in the production of aerosols and suspensions, since it maximizes the interaction between the carrier and dispersed phases.
- the fogging efficiency of the AFF understood as the proportion of the total energy introduced into the system (through the carrier gas) that, in effect, is destined to the surface generation in the dispersed phase, reaches values far superior to those of other pneumatic fogging methods used to date.
- the pressure in the outlet hole of the feed tube (P 1 ) is comprised between the values of the external ambient pressure (P n ) and the pressure (p 0 ) of joint pressurization of gas and liquid.
- the device and method objects of the present invention facilitates the continuous obtaining of a good quality aerosol without resorting to an impeller gas other than atmospheric air or steam from a single source.
- a light pressurization is sufficient to boost fluid mixing and liquid atomization. This ensures very moderate energy consumption, which makes the invention compatible with renewable and self-sufficient sources of energy (solar collector, wind generator).
- the hole and hole edges (10 and 11), or their surrounding environment can have some finishing effect (roughness, toothed, undulating) of characteristic size smaller than the average diameter d, of the jet of liquid that forms in the exit orifice after the exit of said liquid from the exit hole (9).
- This effect can be chosen from the following or similar:
- SUBSTITUTE SHEET (RULE 26) (i) some type of tillage of said canisters (10 and 11), such as a wave or toothed in the radial and / or azimuthal direction of wavelength less than cL
- the height or amplitude of the aforementioned carvings must be greater than the thickness ⁇ of the viscous boundary layer formed by the gas stream on the surfaces (10 and 11).
- SUBSTITUTE SHEET (RULE 26) The small interval between both edges defines a minimum annular passage section that the gas flow has to cross radially then intercepting the jet of liquid emerging from the feed tube. It is a migrated perimeter flow in which a diaphragm flow strangles and disintegrates a liquid stream
- Said minimum annular passage section has an area of the same order as that of the liquid outlet.
- Example of embodiment of the invention The following shows the realization of a real device in which AFF technology has been successfully integrated (see Figure 2).
- Said device consists of a plastic bottle (17) of 2 liters capacity, in whose mouth a plug (18), also plastic, is threaded. The threaded joint must be tight, for which it may be necessary to use a suitable sealant or o-ring.
- an opening (19) through which gas from an external pressurization source is introduced, which in the present embodiment is a diaphragm air pump that consumes 15 watts of power.
- SUBSTITUTE SHEET (RULE 26) 0.4 millimeters in its center, (b) a capillary tube (22) of internal diameter steel 0.4 millimeters with a straight profile at the tip and located 0.1 millimeters away from the inner side of the plate (21), (c ) a plastic positioner (23), whose main mission is to ensure that the capillary (22) is adequately facing the hole of the plate (21) and the desired distance thereof. All these pieces are assembled by snap fit, ensuring that there are no relative movements between the pieces or unwanted leaks outside.
- the capillary tube (22) is connected to the liquid in the bottle with a Tygon ® flexible tube of 0.3 millimeters inside diameter and 2.5 millimeters outside diameter.
- the gas accesses the bottle (2) through the opening (19) existing in the cap (18) and pressurizes the inside of the bottle.
- said gas drives the liquid contained in the bottle, and forces it to rise through the tube (24) that connects the bottom of the bottle with the capillary (22).
- the liquid reaches the mixing zone with the gas at the upper end of the capillary (22), while the gas accesses from the pressurized chamber to the mixing zone through one or several gas through holes ( 25) practiced in the positioner (23).
- the gas and the liquid are mixed giving rise to an aerosol.
- a localized pressure drop (26) is placed, in order to regulate the flow of nebulized liquid.

- the lower chamber which is communicated with the outside
- the volumetric flow of gas that accesses the lower chamber (14) through the Connection port (15) is not negligible, nor is the loss of load caused in said step.
- connection port (15) so that the loss of load suffered by the gas through it is greater than that suffered by reaching the outlet hole (9) of the tube (6), (ie, such that p 0A - p 0B > p 0A - p t ) a differential pressure appears between the ends of the tube (p 0B ⁇ P 1 ) that forces the existing liquid in it to reverse its flow and return to the liquid reservoir (1).
- p 0B ⁇ P 1 a differential pressure appears between the ends of the tube (p 0B ⁇ P 1 ) that forces the existing liquid in it to reverse its flow and return to the liquid reservoir (1).
- said pressure p 0B is the flow pressure of the liquid
- aerosol characteristics such as the flow rate or the droplet size generated can be controlled.
- the actuation of said valve can be controlled automatically or manually (eg an airbrush lever), in the latter case allowing the user to have some "sensitivity" on the produced aerosol.
- the configuration of two chambers with an exhaust valve allows to precisely control the duration of the fogging (start-up and stop), the characteristics of the same and also integrates a cleaning or purge function.
- the wall (12) that separates the upper (13) and lower (14) chambers, or the connection port (15) that joins both cameras it should be stressed that there is no restriction on the nature and characteristics of the wall (12) that separates the upper (13) and lower (14) chambers, or the connection port (15) that joins both cameras.
- connection port between cameras can be designed with a device that prevents the passage of liquid from the lower to the upper chamber.
- FIG. 4 is a variant of the previous one, in which the upper compartment (13) is further subdivided into two enclosures: a pressurization enclosure
- SUBSTITUTE SHEET (RULE 26) (13a) connected directly to said pressurized gas inlet nozzle (5) and a discharge enclosure (13b), surrounding said mixing region; both enclosures being communicated with each other by means of a second connection port (15a) that determines a loss of charge in the gas flow between the two enclosures.
- the purpose of the division into three chambers is to increase the regulation options of the device, especially with regard to the distribution of pressures in the mixing region (Fig. 1, detail).
- a device in which the pressurized container consists of two parts that are assembled together.
- the first one is a chamber (27) filled with gas in which the mixing zone between gas and liquid is integrated.
- the second piece is a liquid container (28) that is assembled in the previous one by any means of union that ensures fixing and sealing (thread, pressure adjustment, etc.).
- the gas is introduced into the device through the nozzle (5), which can be integrated both in the chamber (27) and in the liquid container
- the liquid container can be a reusable reservoir after cleaning or it can be disposable capsules for single use.
- liquid is atomized with a gas (and in general, provided that the carrier phase is less dense than the dispersed phase), the entry of gas into the liquid container can even be made below the free surface of the liquid, so that the gas introduced will form bubbles within the liquid that will subsequently rise and pressurize the upper area to the free surface of the liquid.
- This pressurized gas drives the liquid from the container (28) to the mixing zone (4) through the liquid transport tube (29).
- the container (28) has a valve and is separated from the chamber (27) by a wall in which there is a connection port as explained above for the general device with two chambers and valve escape
- this device integrates all the advantages of the configuration of two chambers with exhaust valve (possibility of cleaning, fogging control, etc.) and the possibility of disassembling the liquid container at will for cleaning functions or recharge
- the feed tube (6) incorporates a charge loss regulator.
- Said charge regulator which can be included in any of the described devices, can consist of a simple fixed obstacle to the passage of liquid (eg a section of small diameter tube, a filter with the appropriate pore size, a frit, etc. .) or it can be an element of variable load loss (eg an externally controlled valve).

- said vaporizable liquid can be chosen from the following substances or combinations thereof: water, CFCs, alcohols, ketones, ethers, esters, paraffins, alkanes, cycloparaffins, naphthenes or cycloalkanes or aromatic hydrocarbons, olefins, alkenes, and other unsaturated hydrocarbons.
- the vaporization of said vaporizable liquid is carried out by heat application.
- This application of heat can be carried out externally, in a separate container with respect to the body of the device (Fig. 7), where the liquid destined to be atomized is stored separately (L 3 ).
- both atomizable (L 3 ) and vaporizable (L v ) liquids are stored in the device together (Fig. 8), with the appropriate separation; and said application of heat jointly heats the liquid to be vaporized and the liquid to be atomized.
- the pressurized bottle or container (2) is surrounded (as in a Thermos bottle) by a vaporizable liquid storage layer.
- the joint heating of both liquids vaporizes, however, only to one of them, the content in the outer layer, which, already in the vapor phase, penetrates into the interior of the pressure chamber through the injection nozzle (5).
- a requirement of this type of drive is that the boiling point of the vaporizable liquid is sufficiently lower than that of the liquid to be atomized.
- An alternative option involves using a solid that is to be atomized as raw material in the device. To do this, the phase change of the latter must be achieved, generally by application of heat.
- the solid can be introduced in the form of granules, powder, tablets or lumps.
- the most favorable configuration is that in which the solid phase destined to become an atomizable liquid and the vaporizable liquid destined to become a discharge steam are stored together with the appropriate separation (double wall thermal bottle type), and are simultaneously heated to an approximately common temperature to ensure the production of working conditions.
- the heat power applied to maintain said common temperature in said two liquid phases is also used as a control parameter of the surface tension and the viscosity of said liquid intended to be atomized. These properties, in effect, are essential for the control of droplet size.
- the invention includes a process for the atomization of a liquid by using a driving gas according to the devices described in the preceding paragraphs.
- the spray or droplet suspension formed is used for humidification or air conditioning of spaces, both interior and exterior.
