Definitions
- the invention relates to a device for spraying a liquid.
- the device according to the present invention is particularly suitable for spraying a high viscosity liquid, such as oil or paint, or some extinguishing agents.
- Patent FR 2 936 715 describes, for example, a device comprising a cylindrical body housing a sliding piston defining on one side a reservoir chamber filled with extinguishing agent and on the other side a chamber containing a generator. gas. When the gas generator is actuated, the gas pressure moves the piston so that the extinguishing agent is expelled from the reservoir, to the ejection member.
- the temperature of the extinguishing agent stored in the tank of such a spraying device is likely to vary widely according to the environment in which said device is located.
- the temperature of the extinguishing agent can drop considerably. In this case, it takes longer for the agent, once sprayed, to evaporate.
- the distance traveled by the extinguishing agent before its evaporation is also longer.
- the viscosity and the density of the extinguishing agent are increased, which results in a lower atomization at equal pressure and for the same ejection member.
- the increase in the viscosity of the extinguishing agent also leads to an increase in the size of the spray droplets, which further contributes to increasing the evaporation time of the agent at the fire zone.
- the sprayed droplets instead of evaporating on the fire zone, impact a cold surface further away and flow along the surface. Thus, the necessary concentration of extinguishing agent is not reached and the extinction of the fire does not occur.
- an object of the invention is to provide a spraying device, ensuring good atomization in a wide range of operating temperature, especially cold, and can be used even with a high viscosity liquid.
- a device for spraying a liquid comprising a reservoir containing the liquid to be sprayed, at least one ejecting member of the liquid, in communication with said reservoir, and a pyrotechnic gas generator for pressurizing the liquid. inside said tank and the propulsion thereof pressurized out of said tank, characterized in that the ejection member is furthermore, in at least one mode of operation, in communication with the gas generator of such that it can be powered by gas generated by said generator.
- the ejection member of the spraying device according to the invention is therefore adapted to be fed with the liquid to be sprayed on the one hand, and with the combustion gas on the other hand, the two circuits, respectively of liquid and gas, joining to create a turbulence inside the ejection member or at the outlet thereof.
- the liquid is dispersed in the form of fine droplets.
- the term liquid / gas mixture means aerodynamic contacting of the liquid with the gas, especially for a short period or at a high speed. Under the effect of aerodynamic shear, the liquid is separated into microdroplets.
- the device ensures a good atomization of the liquid even when it has a high viscosity.
- the ejection member is a bi-fluid nozzle.
- bi-fluid nozzle means here a nozzle supplied by a first liquid circulation circuit to be sprayed and a second gas circulation circuit (the path of the gas having a radial component with respect to the direction of circulation of the liquid) , and configured to allow contact of the liquid and the gas and thus the spraying of the liquid into fine droplets. It is said that such a nozzle is internally mixed when the liquid / gas mixture occurs inside the nozzle, and with external mixing when the mixture takes place outside and at the outlet of the nozzle.
- the device according to the invention is a fire extinguisher, said liquid then being an extinguishing agent.
- the combustion gases generated by the pyrotechnic gas generator being very largely composed of CO 2 , N 2 , H 2 O ( 9 ), the combustion gases injected into the nozzle and thus delivered to the fire simultaneously with the Sprayed liquid can also help increase the extinguishing efficiency of the device.
- the combustion gases injected into the nozzle are all the more effective if they have been cooled by heat exchange with the liquid in the nozzle.
- the gas generator is placed at least partly inside the tank. In this way, a portion of the generated gases can be delivered easily directly into the tank.
- the gas generator is configured for a direct action of the gases released on the liquid.
- the gas generator is configured for an indirect action of the gases on the liquid, via a mobile separation member.
- the mobile separation member is a deformable membrane, in particular an extensible membrane.
- the separating member may also be a sliding piston defining two spaces, one constituting a combustion chamber housing a pyrotechnic charge, and the other constituting a reservoir of liquid to be sprayed.
- the gas generator comprises at least one combustion chamber housing a pyrotechnic charge and a pressurizing chamber communicating with said combustion chamber via at least one gas passage, the pressurization chamber being delimited by the movable separating member.
- the gases feeding the ejection member are taken directly into the combustion chamber and not into the pressurization chamber, to facilitate their adjustment in pressure and / or flow.
- the gas generator comprises at least one combustion chamber housing a pyrotechnic charge, the ejection member is a nozzle, and at least in one mode of operation, the nozzle is in direct communication with said combustion chamber.
- the gas generator comprises a combustion chamber housing at least one pyrotechnic charge, said combustion chamber being arranged so that a portion of the gases generated in said chamber acts on the liquid to put it under pressure. and propel it out of the tank, and so at least in one mode of operation, another part of the gases generated in the same chamber feeds the ejection member, in particular to be mixed with said liquid.
- the device uses only one source of gas to both pressurize the liquid in the tank and supply the nozzle with gas.
- the device also has the advantage of allowing the depressurization of the reservoir and the gas generator through the outlet or openings of the ejection member at the end of operation.
- the gas generator comprises a first gas generating unit comprising a first combustion chamber housing at least a first pyrotechnic charge, and a second gas generating unit comprising a second combustion chamber housing at least a second pyrotechnic charge, said first gas generating unit being arranged such that the gases generated in said first combustion chamber act on the liquid to pressurize and propel it out of the reservoir and said second unit gas generator being arranged so that at least in one mode of operation, the gases generated in said second combustion chamber feed the liquid ejection system, in particular to be mixed with said liquid.
- the reservoir which communicates with a first circulation circuit of the ejection member, is coupled with the first combustion chamber (ie the combustion chamber of the first gas generating unit), while the second combustion chamber (ie that of the second gas generating unit) supplies the second circulation circuit of the ejection member with gas.
- the pyrotechnic gas generator comprises an igniter adapted to jointly ignite the first pyrotechnic charge of the first gas generating unit and the second pyrotechnic charge of the second gas generating unit.
- the pyrotechnic gas generator comprises a first igniter adapted to ignite the first pyrotechnic charge and a second igniter adapted to ignite, independently of the first, the second pyrotechnic charge.
- the spraying device may comprise a control system, in particular an electrical control system, adapted to trigger the first and the second igniter, synchronously or asynchronously.
- the triggering management of the first and second igniter can thus be used to synchronize the arrival of the liquid and the gas to the nozzle.
- the spraying device comprises a temperature sensor inside the tank, and a control member controlling the actuation of the second igniter as a function of the temperature value measured inside the tank.
- the spraying device further comprises a valve for controlling the flow of gas delivered into the ejection member and a temperature sensor located inside the reservoir, said valve being controlled according to the temperature measured by said sensor.

- the gas generator 30 is partially contained inside the tank 10.
- the combustion chamber 36 communicates, via a through orifice 38 of the main body 39. with a pressurizing chamber space 35 located inside the reservoir and delimited by a movable separating member 16.
- part of the gases G generated in the combustion chamber 36 when it is put into operation is delivered directly inside the tank 10, in the pressurization chamber 35 of the generator 30, and the mobile separation member 16 separates the pressurization chamber containing G gases generated by the generator 30, the liquid L contained in the tank 10.
- the separating member 16 is for example an extensible membrane, adapted to deform under the effect of the pressure of the gases G to transmit this pressure to the liquid L contained in the tank 10.
- the reservoir 10 is provided with a member for delivering the liquid L, in particular a frangible membrane 13, openable beyond a certain pressure of said liquid L.
- the gases G coming from the combustion chamber and contained in the pressurizing chamber act on the surface of the liquid via the separation member 16, which prevents the contact between the liquid and gases and thus the formation of an emulsion.
- the delivery member 13 opens and the liquid L is delivered, under pressure, into a pipe 14 connecting the reservoir 10 to the ejection member 20.
- the device is a fire extinguisher
- the liquid L is an extinguishing agent, in particular of the non-flammable hydrofluoroether (HFE) type, as described in the patent application EP 1 782 861.
- HFE non-flammable hydrofluoroether
- the pyrotechnic charge 34 consists, for example, of a compound such as those described in patent applications WO 2006/134311 or WO 2007/042735, and in particular those consisting essentially of guanidine nitrate and of basic nitrate. copper which are well suited in the context of the present invention. Those skilled in the art will be able to adapt the geometry, the mass and the composition of the pyrotechnic charge 34 according to the desired flow rates and operating times.
- the pyrotechnic gas generator 30 further comprises at least one orifice 42 of diameter adapted to the desired gas flow, opening into the combustion chamber 36 and connected to a duct 40 supplying the organ ejection of the liquid 20.
- the pyrotechnic charge is preferably selected from compounds generating little or no solid effluent, it is not excluded that solid particles are produced and driven through the conduit 40 to the ejection member 20.
- a particle filter 44 is therefore advantageously implanted on the conduit 40 supplying the ejection member 20, to prevent it being clogged by the solid particles from the gas generator 30.
- the ejection member 20, supplied with extinguishing agent L contained in the reservoir 10 via the conduit 14, and with gas from the combustion chamber 36 via the conduit 40, is illustrated in more detail. detail in Figure 2A.
- the ejection member 20 is here a nozzle of the so-called "bi-fluid" type. It comprises, in this example, two coaxial tubes 71, 72, defining an internal circulation circuit 73 defined by the tube 71 of smaller diameter, and an external circulation circuit 74 defined between the outer face of the tube 71 and the inner face tube 72 of larger diameter.
- the internal circulation circuit 73 is connected to the duct 12 communicating with the tank 10 and the external circulation circuit 74 is connected to the duct 40 communicating with the combustion chamber 36.
- the bi-fluid nozzle 20 is an internal mixing nozzle, that is to say that the aerodynamic contacting between the gas and the liquid is carried out inside the nozzle 20.
- the outer tube 72 has a constriction 75 at its distal end.
- the distal end 76 of the inner tube 71 is located inside the outer tube 72, just upstream.
- the two tubes 71, 72 therefore have their ends offset with respect to each other, so that the air and gas flows converge inside the nozzle and come into dynamic contact with each other. before leaving the nozzle through the opening 77 of the outer tube 72.
- FIG. 2B Another example of a nozzle 20 'adapted to be used in the spraying device according to the present invention will now be described with reference to FIG. 2B.
- the elements having the same function as in FIG. 2A comprise the same numerical references added with a prime sign.
- the nozzle 20 ' differs from the nozzle 20 of FIG. 2A in that the mixing between the gas and the liquid is achieved by the convergence of the two flows, coming respectively from the internal circulation circuit 73' and from the external circulation circuit 74 ' at the outlet of the nozzle 20 '. So we are talking here of bi-fluid nozzle with external mixing.
- the two tubes 71, 72 having their ends aligned, the gas and the liquid out of the nozzle before being able to be mixed.
- the outer tube 72 ' is narrowed at its end, so that its flow section is progressively decreased.
- the reduction of the flow section of the gas causes an increase in its speed, which improves the efficiency of the mixture.
- the spraying device 100 is actuated by the triggering of the igniter 32 and, in fact, the combustion of the pyrotechnic charge 34 inside the combustion chamber 36.
- the gas flow is turbulence in the liquid arrival zone at the nozzle.
- the gas bursts the liquid and throws microdroplets towards the target.
- the depressurization of the combustion chamber 36 is achieved through the outlet orifice of the nozzle 20. Additional depressurizing members, if they can be provided, are however not necessary.
- the device 100 further comprises a temperature sensor 54 located inside the reservoir 10 and preferably in contact with the liquid L contained in this reservoir, a controllable valve 50 on the conduit 40 for transporting gas and a control member 52 of the valve as a function of the value or values measured by the temperature sensor 54.
- the valve 50 is controlled to adjust the gas flow, and the correct proportion of gas is injected into the nozzle 20 ensuring the required atomization quality of the liquid.
- the liquid to be sprayed L will have a sufficiently low viscosity and, in general, a sufficiently high temperature, so that its diffusion is effected effectively without heating or prior mixing with gas.
- the control member of the valve may control its complete closure during spraying and the nozzle will operate as a liquid single-fluid nozzle.
- the device will be provided with a device for regulating the pressure in the combustion chamber of the gas generator, for example a leak orifice for the gases, controlled at the opening or closing according to the pressure in the gas generator.
- This regulating member may in particular be constituted by the valve 50 itself, the latter being configured to assume a position in which the duct 40 is closed, but a portion of the gases contained in the combustion chamber may be deflected outwards. .
- FIG. 4 schematically and partially shows a spraying device 200 according to a second embodiment of the present invention.
- the device 200 differs from that described above by the configuration of its gas generator 130.
- the gas generator 130 here comprises a first gas generating unit 81 and a second gas generating unit 82, each comprising a combustion chamber 36a, 36b and at least one pyrotechnic charge 34a, 34b housed in said chamber 36a, 36b, and the gas generator 130 further comprises an igniter 32 connected to the two gas generating units 81, 82 and adapted to jointly fire the two pyrotechnic charges 34a, 34b.
- the first combustion chamber 36a communicates with a pressurizing chamber 35 inside the tank 10 by at least one through-hole 38. All the gases G1 generated in the first combustion chamber 36 are delivered to the inside the tank, in the pressurization chamber 35 delimited by a transmission element 16 of the deformable membrane type identical to that of Figure 1. As in the first embodiment described above, the G1 gases contained in the pressurizing chamber act on the liquid L. In the example shown, this action is indirect and is via the transmission element 16.
- the second combustion chamber 36b is here connected to the nozzle
- the leakage orifice (s) 42 of the second combustion chamber 36b communicate exclusively with the nozzle 20.
- a combustion chamber is adapted to generate gases G1 intended to pressurize the liquid L and to propel it towards the ejection member 20, while the second combustion chamber, independent of the first, is intended to supply the gas ejection member G2.
- the first and second pyrotechnic charges may be chosen independently of one another to satisfy the constraints specific to their respective function.
- the second pyrotechnic charge may consist of a compound of the type of those described in patent application WO 2009/095578, a nitrogen generator (inert quenching gas), comprising for example essentially azidocrabonamide. and a nitrogen reducing charge, the first pyrotechnic charge can then contribute to the supply of heat necessary for their decomposition.
- FIG 5 there is shown schematically and partially a spraying device 300 according to a third embodiment of the present invention.
- the device 300 differs from that of FIG. 4 only in that its pyrotechnic generator 230 comprises two separate igniters 32a, 32b, the first of the two igniters being configured to ignite exclusively the first pyrotechnic charge (s). s) 34a located in the first combustion chamber 36a of the first gas generating unit 81 and the second igniter 42b being configured to ignite exclusively the second (s) 34b load (s) located in the second combustion chamber 36b of the second gas generating unit 82.
- first and second igniter can be triggered by a common control unit or by own control units, including electrical control units.
- the first and second igniter can be triggered synchronously or asynchronously.
- a temperature sensor 54 is provided inside the tank 10, preferably in contact with the extinguishing agent L.
- a firing member 56 forming a control unit for the second igniter 32b is connected to this temperature sensor 54, as well as the second igniter 32b previously described.
- the second igniter 32b igniting the second pyrotechnic charge 34b can thus only be fired if the temperature conditions to which the spraying device 300 is subjected require operation of the nozzle in a bi-fluid regime to ensure good atomization of the agent. In the opposite case, it is not fired and the nozzle 20 then functions as a monofluid nozzle supplied solely with the extinguishing agent.
- the two gas generating units 81, 82 and their respective igniters 32a, 32b can also be spaced apart. All other aspects remaining, moreover, identical to those described with reference to FIG.
