    The present invention relates to the field of processes for treating an atmosphere and devices implementing these methods.
    In the context of sanitation technologies of an atmosphere involving the diffusion of a cleaning agent in solution in finely divided form in the atmosphere to be sanitized, the invention proposes to cause the division of such a solution by effect. piezoelectric. While following the technique that is currently commonly used, the solution is sprayed by dragging it into an air jet which projects it into droplets to create a mist, the invention provides for causing the misting of the solution in the passing over piezoelectric membranes urged to vibrate to create a plurality of fog masses.
    This technique, known in itself under the notions of misting or nebulization, produces a mist of liquid particles suspended in the surrounding air in the vicinity of the piezoelectric membrane. According to the invention, it is this fog that is carried away from the membrane in the atmosphere to be sanitized. All that is required is a low-speed ventilation stream that renews the environment of the membrane, which can then be channeled into the atmosphere to be treated in sanitation. There is no need for the high speeds that are necessary in spray-spraying techniques, and the diffusion of the treatment product to the surroundings takes place without boiling or turbulence. The invention more specifically proposes a process for cleaning up an atmosphere to be treated, in which a sanitizing mist is produced by subjecting a purifying liquid to the vibrations of piezoelectric membranes, by conveying different masses of fog thus produced by a plurality of currents. individualized air which respectively drives them away from the membranes by guiding them individually to a specific place in the atmosphere to be treated.
    In practice, a fogging battery with piezoelectric membranes is preferably used in the process.
    Advantageously, according to the process of the invention, the various membranes are fed continuously with cleaning liquid by ensuring the recirculation of the liquid not consumed in the production of fog.
    Preferably according to the invention, the piezoelectric membranes are fed by channeling the sanitizing liquid into different cuvettes at the bottom of which said membranes are respectively present.
    Preferably according to the invention, it ensures the recirculation of the liquid not consumed in the formation of fog, by overflowing said liquid out of said cuvettes to a feed tank containing sanitizing liquid.
    Preferably according to the invention, it controls the amount of liquid consumed for the production of fog over time.
    The control of this quantity of liquid consumed in combination with the recirculation of the unconsumed liquid makes it possible to know the quantity of fog diffused into the atmosphere to be treated and thus to make sure that it is sufficient to purify the atmosphere.
    Advantageously according to the invention for driving the fog masses, a flow of air is circulated in an open circuit which is distributed to form different ascending air currents which drive the fog masses to the atmosphere to be treated.
    The different air streams are thus ventilated to the jets produced by the various layers of liquid subjected to vibration of the different piezoelectric membranes, to individually drive each mass of fog by licking said jet to an outlet dedicated thereto.
    In addition, according to a preferred case of the invention, the fog masses individually guided to the atmosphere are moved by additional air ventilation which disperses them in the atmosphere and makes it possible to better reach the different surfaces in the atmosphere.
    According to the process of the invention, an aqueous liquid is preferably used. In particular for sanitizing the atmosphere, a sanitizing liquid containing in solution a sanitizing agent chosen from biocidal agents and phytosanitary products is used. For example, hydrogen peroxide is used as the biocidal agent. The invention also relates to an apparatus capable of implementing the method which has just been described. The invention thus proposes an apparatus for sanitizing an atmosphere to be treated which comprises means for producing a mist by vibrating piezoelectric membranes, said apparatus comprising at least one misting battery of a purifying liquid equipped with piezoelectric membranes. , and means for conveying different masses of the fog thus produced by a plurality of individual air currents respectively driving the different fog masses away from the membranes by guiding them individually to a specific location of the atmosphere to be treated.
    Preferably the apparatus according to the invention comprises different cuvettes in which are respectively disposed different piezoelectric membranes of said misting battery and in that it is associated with means for adjusting the flow of liquid misted by maintaining a liquid level at constant height above the corresponding membrane, in particular by overflow of the liquid above a bowl wall. Said cups are associated with the mist battery to produce the fog.
    Advantageously according to the invention, said apparatus comprises a machined block for producing individualized fog masses. This block incorporates the fogging battery and is individually machined therein the different piezoelectric membrane receiving wells and a plurality of internal fog collection cavities each opening into an ascending fog guide duct towards the atmosphere to be treated, said fog being driven and guided by an updraft admitted into the corresponding cavities above said cuvettes.
    Preferably according to the invention, said apparatus comprises a reservoir containing the sanitizing liquid for supplying the piezoelectric membranes with liquid, via the cuvettes surrounding the membranes.
    Preferably a network of channels machined in the block fed by a pipe connected to the liquid reservoir serves each membrane.
    Preferably the apparatus comprises a weighing module responsive to the weight of said reservoir and means for determining the amount of liquid consumed for the production of the fog masses over time as a function of the weight of the reservoir determined by said weighing module.
    Preferably according to the invention, said apparatus comprises means ensuring the recirculation of liquid overflowing cuvettes to said reservoir, by spillway conduits.
    In particular according to the invention, the apparatus comprises means for injecting an air flow into the tank, said means comprising a fan located outside said block and said tank, and means for distributing this flow of water. air to said different fog collecting cavities produced by the membranes in said wells.
    Advantageously according to the invention, the ducts for the individual guidance of the different fog masses, have a bent shape on an upward path, this shape preventing the passage of too large droplets of liquid, to produce a dry feeling fog. The bent shape can be in the form of an "S".
    Preferably the apparatus according to the invention further comprises additional means of air blowing, located at the outlet of the fog guide ducts, said means being disposed outside said block and so that the masses fog out of the guide ducts in the atmosphere does not come into direct contact with these means so as to avoid recombination of the mist droplets between them.
    According to a particular case of the invention, the spillway ducts bringing the liquid overflow from the bowls are connected on the one hand to slots machined in the block opening respectively into the cavities of the block and on the other hand to the upper part of the tank. the spillway ducts also serving as means for distributing the flow of air injected into the reservoir towards said cavities.
    In the particular case of liquids with surfactant properties that can produce foam during their implementation, advantageously according to the invention, the different cavities machined above the bowls are arranged so that the different updrafts of fog training which run respectively respectively are deflected to the upward part of the spurting jet springing from the bowl, thus avoiding the contact of this air with the jet when it comes into contact with a wall of the cavity, contact creating the foam. A sloping inner wall disposed in the inner extension of the outer wall of the machined block deviates said stream of air entering the cavity while the fogging jet has fallen back into the retaining delimited by this sloping wall and said outer wall of the block. A rerouting channel connecting said retainer and the bowl of the piezoelectric membrane allows the liquid collected in said reservoir to be recirculated. Such an arrangement therefore avoids causing foam in the fog discharging into the atmosphere to be treated. The apparatus according to the invention may comprise a plurality of misting batteries, each respectively integrated in a machined block and each associated with a plurality of ascending airflow guide ducts, the sanitizing liquid supply tank being common to said batteries. It is then possible to sanitize a wider area and reach different surfaces by spreading the sanitizing fog more widely, misting batteries and fog guiding ducts being arranged adequately.
    Advantageously according to the invention, the apparatus may be mobile, in particular robotized, in that it comprises a mobile frame carrying the misting batteries and means for controlling its movements to make it travel the ground surface serving the atmosphere. to treat by partition of this surface in corridors from an autonomous cartography or data acquired by learning. The invention will now be more fully described in the context of preferred features and their advantages, with reference to FIGS. 1 to 10, in which: FIG. 1 schematically illustrates an apparatus for producing a sanitizing mist, according to a view partial cross section, which operates according to the method of the invention; - Figure 1A illustrates schematically and partially, in a view from above, the apparatus of Figure 1; - Figure 2 schematically illustrates in perspective and partially the apparatus of Figure 1; - Figure 3 illustrates schematically, in a partial longitudinal sectional view, the apparatus shown in Figures 1 and 2; - Figure 4 schematically illustrates in cross section a portion of an apparatus according to the invention in connection with Figures 1 to 3; - Figure 5 is schematically illustrated in perspective of three-quarters and in plan view a portion of an apparatus according to the invention in connection with Figures 1 to 4; FIG. 6 illustrates a mobile device incorporating devices as illustrated in FIGS. 1 to 5 and 7, in a three-quarter perspective view; Fig. 6A shows a cross-sectional view of the mobile apparatus illustrated in Fig. 6; - Figure 7 illustrates schematically in perspective of three-quarter a partial view of the interior of a device in connection with the preceding figures; - Figure 8 schematically illustrates a variant of an apparatus for producing a sanitizing mist, partially seen in cross section, operating according to the method of the invention; FIG. 9 schematically and partially illustrates the apparatus of FIG. 8 in an exploded, three-quarter perspective view; - Figure 10 schematically illustrates, in a partial view in longitudinal section, the apparatus shown in Figures 8 and 9.
    Not all components are represented on the same scale for the sake of clarity.
    FIGS. 1 to 7 illustrate an apparatus for producing fog mass sanitizing by nebulization of a solution, operating according to the atmosphere purification method of the invention, FIGS. 6 and 6A illustrating the mobile mounted device for cleaning up an atmosphere. The apparatus is in the form of a sanitizing mist mass generating device which comprises a piezoelectric membrane misting battery 10, which according to this example is in the form of a double row of five piezoelectric membranes. Each piezoelectric membrane 11, 12 is according to this example a ceramic membrane, vibrated by connecting the mist battery by the electrical cord 101 to a power supply, which produces a jizzing liquid jet J11, J12 when a solution L is subjected to vibrations of said membrane.
    The vibrations of the piezoelectric membranes are produced as commonly at ultrasonic frequencies.
    According to the invention, the battery of piezoelectric membranes 10 is capped with a block B1 specially machined so that according to this example each piezoelectric membrane 11, 12, 14 is individualized at the bottom of a bowl 111, 112, 114 machined in said block.
    According to the particular embodiment illustrated by the figures, the mist battery is covered by the machined block, and is disposed on the cover R1 of a tank R containing the solution L which will be nebulized by said device to produce a plurality of masses resourceful. The misting battery is not immersed in the solution to be sprayed. This solution may be an aqueous liquid containing a sanitizing agent, for example a biocidal agent, a phytosanitary product or any other compound to be diffused into the atmosphere, dissolved in water.
    The solution L in the tank R is pumped by means of a pump P and then sent via a pipe to the piezoelectric battery 10 by means of connecting pipes T11, T12 respectively to the orifices 01, 02 hollowed out in said block machined B1 entering the solution to respectively channels C1, C2 machined in said bioc B1 parallel and respectively to a row of piezoelectric membranes, a channel C1, C2 being connected by bypass conduits respectively to the bowls of the piezoelectric membranes of its row, to supply each piezoelectric membrane with solution. A certain height of liquid is maintained above each ceramic membrane, which vibrates, agitates this layer of liquid to create a bruising jet such that jets referenced J11, J12 in Figure 1, which spring to the plumb 111,112 respective cups of the piezoelectric membranes 11, 12, in internal cavities 121, 122 which respectively extend the cuvettes.
    The method according to the invention provides that the liquid supply L of the piezoelectric battery is looped, each membrane being fed continuously by controlling the liquid supply by overflow at each membrane. According to the embodiment illustrated in FIGS. 1 to 4, at the level of each piezoelectric membrane 11, 12, a light, such as the light 123 in FIG. 3, is produced in the machined block B1 in order to insert the upper end thereof. an overflow duct 311, 312 which returns the excess liquid if 11, if 12 to the tank R, said duct being connected by its lower end to the tank through a through hole provided in the cover R1 of the tank. The level of liquid in the bowl, and therefore above the membrane, is thus managed by the height of the bowl wall and the position of this light located in the upper part of a reference wall of the bowl.
    Furthermore, according to the embodiment illustrated in particular in Figures 1 to 3 and 7, the air flow distributed in a plurality of updrafts to cause the fog mass M11, M12 extracted by licking the jet scrambling J11, J12 comes from air blown A from an external fan VA (Figure 7) to the tank R containing the liquid in the upper part of said tank free of liquid. This air flow is then distributed in different ascending air streams to be directed at the outlet of the cuvettes, directly above the membranes, in the internal cavities of the block and into the guide ducts of the fog masses in the chamber. atmosphere to be treated. This distribution in air currents is carried out by making each flow-duct 311, 312 used to recover the excess liquid overflowing, as it is represented by the arrows inside the device, through said flow of incoming air. The amount of surplus liquid for each piezoelectric membrane is relatively small so that there is enough space in the spillway for the air to flow countercurrent surplus liquid.
    Preferably, each scrambling jet J11, J12 is directed towards a guide duct towards the atmosphere formed according to the example by a guide pipe 411, 412 whose lower end is connected to an internal cavity outlet orifice of the block, machined directly above the respective piezoelectric membrane, so that the fog mass M11, M12 caused by the upward air flow is directed towards the outlet 4110, 4120 of the guide pipe 411, 412 opening into the atmosphere to be treated. Preferably said guide pipes 411, 412 have an "S" bent shape which allows too large drops of liquid, which could condense together, to fall back into the bowl of the piezoelectric membrane instead of escaping with the mass of mist consisting of fine droplets of solution. The apparatus thus makes it possible to create individualized fog masses, which form a "dry" sanitizing mist. These fog masses being individualized with respect to each other, they can not recombine to condense and create a humid fog.
    Advantageously according to the invention, an additional air flow, represented by the arrows V in FIG. 1, is ventilated at the levels of the outlets of the guide ducts of the fog masses in order to propel the fog masses M11, M12 outgoing, in any the atmosphere to be treated, using ventilation means such as recovery fans V1, V2 arranged on the shell D covering the guide pipes (see diagrammatic figures 4 and 5), for example between the rows of the outlets of the device, and so that the fog masses do not come into contact with the fans itself, thus avoiding the recombination of the mist droplets between them.
    To sanitize an atmosphere, a mobile apparatus is preferably used as illustrated in FIGS. 6 and 6A.
    According to this example, the apparatus comprises two batteries of misting membranes with piezoelectric membranes 10, 20, each surmounted by a machined block B1, B2 in a configuration according to that described in FIGS. 1 to 3, said misting batteries 10, 20 resting on the lid of the same tank R which contains the solution L to be sprayed. Each of the misting batteries 10, 20 is supplied with liquid L from this same tank R by a pump P (see schematic figure 7). The reservoir is filled with liquid L by the feed mouth R2. The blown air A in the two machined blocks B1 and B2 is produced by a common fan VA (see schematic figure 7) whose generated air is conveyed by a pipe A1 to the upper part of the tank, free of liquid.
    Advantageously according to this example, the tank R rests on a weighing module W, sensitive to the weight of the tank, which makes it possible to follow the quantity of liquid consumed for the production of the masses of fog over time, which makes it possible to know in fine the fog flow rate and thus to check whether it is in adequacy with the volume of the atmosphere to be treated. This monitoring also makes it possible to predict when it is necessary to replenish said device with a sanitizing liquid.
    Advantageously, the return of the device to a base to recharge it in liquid can thus be managed by a computer program on board the device or by wireless connection with a remote computer.
    The weighing module W and at least a portion of the tank R are arranged in a chassis C, mounted on wheels. The chassis C preferably also comprises an electric battery G, a source of energy for the motion of the apparatus and the operation of the various equipment requiring a source of energy such as piezoelectric membranes, fans, the pump, the various programming means.
    Advantageously, the apparatus is programmed to traverse the ground surface serving the atmosphere to be treated by partitioning this surface in corridors to be traveled, from an autonomous cartography or data acquired by learning following the recording of a first course. performed by an operator.
    FIGS. 8 to 10 illustrate a variant of a device for nebulizing a solution for the production of sanitizing mist masses, operating according to the atmosphere purification method of the invention. This device is particularly suitable for nebulizing solutions that have surfactant properties that may cause the formation of foam during their implementation.
    As for the fog mass production apparatus previously described, a piezoelectric membrane misting battery is used, surmounted by a machined block that makes it possible to have different piezoelectric membranes respectively arranged in different cuvettes in order to produce different masses of fog.
    The machined block B3 of the apparatus according to this example is designed so that the jets produced by the different layers of liquid vibrated by the piezoelectric membranes strike a wall away from the ascending air currents which could cause with fog, the foam that forms when the jet hits the inner walls of the block. The apparatus according to this example comprises a mist battery 30 which, according to this example, is in the form of a double row of five piezoelectric elements, each formed of a ceramic membrane, vibrated by a power supply, and surmounted by a cone, open in its base and its summit, to direct the jet of brouillassant liquid, which emanates the fog, which is formed during the nebulization of a solution.
    Block B3 is machined internally so that each piezoelectric membrane 31, 32 is individualized at the bottom of a bowl 310, 320 which receives the liquid to be liquidized from a tank R 'and conveyed by a pipe to the orifices of entry of the liquid dug into the block B3. These orifices are the respective inlet of channels C '1 and C'2 hollowed out symmetrically in the block B3, parallel and respectively to a row of piezoelectric membranes, respectively to supply liquid to the rows of piezoelectric membranes, the liquid borrowing an individualized bypass C'31, C'32 opening into the cuvette surrounding the piezoelectric element considered, the liquid penetrating to the piezoelectric membrane through orifices through the cone above said membrane. The liquid level above the membrane is managed by overflow of the liquid above a wall of the bowl whose height sets this level, the overflow liquid sl31, sl32 in this example flowing through a groove forming weir 631, 632 excavated in the machined block towards the central portion of the piezoelectric battery to fall back into the support 300 of the piezoelectric battery, without rising wall on one of its transverse sides 310 to allow the flow of said surplus liquid to the tank R '. This support 300 being disposed in the upper part of the tank R ', above the highest level of liquid, the overflowing liquid thus falls into the tank R' without however the misting battery is immersed in the solution to be sprayed contained in said tank. The tank R 'is further closed by a cover R'1 in which is inserted the lower part of the machined block B3.
    The layer of liquid above each membrane 31, 32 in vibration is nebulized producing a jetting liquid jet J, J ', which emanates the fog, which springs from the cone surmounting the membrane in a cavity 531,532 dug in the machined block B3.
    A ventilated air flow, represented by the arrows A 'in FIG. 8, is distributed in ascending air currents by entering the inlet mouths 331, 332 dug in the outer wall of the block B3, opening respectively at the level of each piezoelectric element 31, 32 is deflected by a sloping wall 5310, 5320 present in the cavity 531, 532 hollowed out in the block, in extension of the inner surface of the outer wall of the block in order to direct this air towards the inner part from the cavity where the scrambling jet is ascending and towards the guide duct of the fog mass M31, M32 extracted by said air by licking the scrambling jet. The air stream thus causes fog at the upstream portion of the jet, before said jet contacts an inner wall of the block to create foam. The fog is thus extracted from the jet without foam.
    The fogging jet falls from the side striking the walls of the cavity which are out of the upward path of the air current, the liquid of the jet not discharged in the form of fog is then contained in the restraint formed by the space delimited by this same sloping wall and the outer wall of said block. The collected liquid 131, I32 in this reservoir is rerouted to the bowl of the piezoelectric element considered 31, 32 via a channel C31, C32 dug in said block connecting said reservoir and the cuvette.
    The sloped wall 5310, 5320 acts as a deflector for the flow of air entering the cavity and allows the liquid to be retained with the foam.
    The mass of fog M31, M32 is driven without foam by the upward air flow which travels through its cavity 531, 532 of the block B3 and guided in the guide duct 431, 432 of the machined block B3, to the light dug in the upper wall of said block connected according to this example with an additional block B30 disposed in extension of the main block B3. This additional block B30 extends the guide duct of the fog mass so that the complete guide duct of the fog mass has a bent shape, in "S", on its upward path, to retain the large drops of liquid present in the fog jet.
    As outputs of the additional block, are arranged recovery fans V3, V4 which generate an additional air flow V 'helping to diffuse the outgoing fog masses in the atmosphere to be treated. These recovery fans are located just below the fog outlets so that the fog masses do not have to cross them at the risk of causing condensation.
    As for the previous example described in FIGS. 1 to 7, the apparatus makes it possible to create different fog masses, at the level of each piezoelectric membrane, which can not recombine to condense, and thus form a "dry-feeling" sanitizing mist. ". The apparatus illustrated in FIGS. 8 to 10 may be mounted in several copies arranged symmetrically on a mobile frame in a manner similar to that described in FIGS. 6 and 6A, using a single tank R ', the fitting being adapted to the characteristics of this variant. of device.
    However, it follows from the foregoing that the invention is not limited to the embodiments that have been specifically described and shown in the figures and that it extends to the contrary to any variant. The method can be applied to treat an atmosphere to be sanitized, any environment including all surfaces present and accessible in this place, for example by the use of a biocidal agent dissolved in an aqueous medium, and also to diffuse a phytosanitary agent on plants, especially in a greenhouse, or any other active agent. The device may be equipped with one or more piezoelectric membrane misting batteries.
