Description

Dispositif de désinsectisation Disinsection device
L'invention concerne d'une manière générale la désinsectisation des locaux tels que les locaux industriels ou agricoles.The invention relates generally to disinsection of premises such as industrial or agricultural premises.
Pour désinsectiser un local, il est connu de procéder par pulvérisation d'un produit liquide dit traditionnel, en utilisant un pulvérisateur du typeTo disinsect a room, it is known to spray a liquid product called traditional, using a sprayer type
Λ ' Vermorel ' ' qui disperse ce produit sous forme de goutelettes . Λ 'Vermorel' which disperses this product in the form of droplets.
Cette méthode permet de tuer les insectes à sang chaud adultes, mais elle ne permet pas de tuer les larves. En conséquence, il est nécessaire de procéder à une nouvelle opération de pulvérisation toutes les deux à trois semaines, cette période correspondant au temps nécessaire à une larve pour devenir adulte. Ce type de' désinsectisation représente une charge de travail importante puisqu'un opérateur doit à intervalle régulier préparer un pulvérisateur, procéder à la pulvérisation, puis nettoyer le pulvérisateur pour l'utiliser ultérieurement. II existe d'autres méthodes du même type consistant par exemple à utiliser un nébulisateur ou un thermonébulisateur, mais elles présentent les mêmes inconvénients du fait qu'elles consistent à générer du brouillard. Si l'on place un écran devant l'un ou l'autre de ces dispositifs en fonctionnement, cet écran devient humide .This method kills adult warm-blooded insects, but does not kill the larvae. Consequently, it is necessary to carry out a new spraying operation every two to three weeks, this period corresponding to the time required for a larva to become an adult. This type of 'pest represents a significant workload since an operator must at regular intervals prepare a spray, proceed to spray and clean the sprayer for later use. There are other methods of the same type consisting for example of using a fogger or a thermal fogger, but they have the same disadvantages because they consist in generating fog. If a screen is placed in front of one or the other of these devices in operation, this screen becomes wet.
Selon une autre méthode, on utilise comme produit désinsectisant du bromure de méthyle appliqué sous forme gazeuse. Qu'ils soient adultes ou sous forme de larve, les insectes sont tués, car grâce à l'utilisation d'une forme gazeuse, le produit désinsectisant pénètre dans tous les recoins et sur toutes les surfaces du local à traiter. Bien que communément appelée fumigation cette méthode consiste à générer un gaz, et non pas de la fumée. La forme gazeuse est apte à pénétrer des surfaces orientées dans toutes directions, y compris des surfaces orientées vers le bas, ce qui rend cette méthode très efficace en particulier vis-à-vis des larves.According to another method, methyl bromide applied in gaseous form is used as a disinsectant product. Whether adults or larvae, insects are killed because, thanks to the use of a gaseous form, the disinsectant product penetrates into every nook and every surface of the premises to be treated. Although commonly referred to as fumigation this method involves generating a gas, not smoke. The gaseous form is able to penetrate oriented surfaces in all directions, including downwardly facing surfaces, which makes this method very effective especially with respect to the larvae.
Avec cette autre méthode, le local doit être désinsectisé à une fréquence plus faible, par exemple une ou deux fois par an ce qui rend son coût de revient beaucoup plus compétitif, puisqu'elle tue les insectes adultes et les larves. Cependant, les émanations de bromure de méthyle détruisent la couche d'ozone, de sorte que l'utilisation de ce produit est en cours d'interdiction dans le cadre de la désinsectisation .With this other method, the room must be disinsected at a lower frequency, for example once or twice a year, which makes its cost more competitive, since it kills adult insects and larvae. However, methyl bromide releases destroy the ozone layer, so the use of this product is banned in the context of disinsection.
Le but de l'invention est d'apporter une solution simple pour désinsectiser un local sans devoir utiliser de bromure de méthyle, mais sans générer une charge de travail trop importante.The object of the invention is to provide a simple solution for disinsecting a room without having to use methyl bromide, but without generating too much workload.
A cet effet, l'invention a pour objet un dispositif de désinsectisation d'un local, tel qu'un local industriel ou agricole, destiné à être installé à demeure dans ce local, ce dispositif comprenant un récipient de liquide de désinsectisation et un récipient de liquide de rinçage, une électrovanne à trois voies reliée par trois tubes aux deux récipients et à la pompe et une buse reliée à cette pompe pour éjecter par la buse le liquide de désinsectisation ou le liquide de rinçage, et des moyens de commande permettant de déclencher des cycles de désinsectisation, chaque cycle comprenant une phase de désinsectisation par éjection du liquide de désinsectisation via la buse suivie d'un phase de rinçage par éjection du liquide de rinçage via la buse.For this purpose, the subject of the invention is a disinsection device for a room, such as an industrial or agricultural room, intended to be permanently installed in this room, this device comprising a disinfecting liquid container and a container. rinse liquid, a three-way solenoid valve connected by three tubes to the two containers and to the pump and a nozzle connected to this pump for ejecting by the nozzle the disinsectant liquid or the rinsing liquid, and control means for trigger disinsection cycles, each cycle comprising a disinsection phase by ejection of the disinsectant liquid via the nozzle followed by a rinsing phase by ejection of the rinsing liquid via the nozzle.
Avec ce dispositif, l'utilisateur peut réaliser des cycles de désinsectisation pour tuer les insectes adultes, toutes les deux à trois semaines, sans avoir à manipuler à chaque fois le produit de désinsectisation. Ceci permet de maintenir le local continûment désinsectisé sans avoir à utiliser de bromure de méthyle.With this device, the user can perform disinsection cycles to kill adult insects, every two to three weeks, without having to handle the disinsectant product each time. This keeps the room continuously disinsected without the use of methyl bromide.
L' invention concerne également un dispositif tel que défini ci-dessus, comprenant un réchauffeur monté en amont de la buse, pour éjecter le produit de désinsectisation sous forme de fumée.The invention also relates to a device as defined above, comprising a heater mounted upstream of the nozzle, for ejecting the disinsectant product in the form of smoke.
L' invention concerne également un dispositif tel que défini ci-dessus, comprenant une pompe de mélange reliée au récipient de liquide de désinsectisation par un tube d'entrée et un tube de sortie, ainsi que des moyens de commande actionnant automatiquement la pompe de mélange de façon périodique.The invention also relates to a device as defined above, comprising a mixing pump connected to the disinsectant liquid container by an inlet tube and an outlet tube, and control means automatically actuating the mixing pump. periodically.

L' invention concerne également un dispositif tel que défini ci-dessus, comprenant une console de commande incluant au moins un interrupteur de déclenchement de cycle de désinsectisation, cette console étant distincte d'une structure dans laquelle sont montés les récipients, la pompe et la buse, cette console étant reliée à la structure par des câbles électriques.The invention also relates to a device as defined above, comprising a control console including at least one disinsectisation cycle release switch, this console being distinct from a structure in which the containers, the pump and the nozzle, this console being connected to the structure by electric cables.
L' invention concerne également un procédé de désinsectisation d'un local tel qu'un local agricole ou industriel avec un dispositif tel que défini ci-dessus, dans lequel on ajuste la durée de la phase de désinsectisation à une valeur telle que le volume de fumée généré pendant l'ensemble de cette phase de désinsectisation correspond à trois fois le volume du local à traiter.The invention also relates to a method of disinsecting a room such as an agricultural or industrial room with a device as defined above, in which the duration of the disinsectisation phase is adjusted to a value such that the volume of The smoke generated during this entire phase of disinsection corresponds to three times the volume of the room to be treated.
L'invention sera maintenant décrite plus en détail, et en référence aux figures annexées. La figure 1 est une vue de l'armoire du dispositif selon l'invention ;The invention will now be described in more detail and with reference to the appended figures. Figure 1 is a view of the cabinet of the device according to the invention;
La figure 2 est une vue des organes du dispositif selon l'invention ;Figure 2 is a view of the organs of the device according to the invention;
La figure 3 est une vue de la console de commande du dispositif selon l'invention.Figure 3 is a view of the control console of the device according to the invention.
Le dispositif selon l'invention qui est représenté en figure 1 comprend une structure 1, ou armoire, fermée par une porte 2 et une console de commande 3 reliée à cette armoire par un ensemble de câbles électriques 4.The device according to the invention which is represented in FIG. 1 comprises a structure 1, or cabinet, closed by a door 2 and a control console 3 connected to this cabinet by a set of electric cables 4.
La structure 1 est pourvue de moyens de fixation à des éléments fixes du local, ces éléments fixes étant un ensemble de poutres supports repérées par 6 dans l'exemple des figures.The structure 1 is provided with fixing means to fixed elements of the room, these fixed elements being a set of support beams marked by 6 in the example of the figures.
L'armoire renferme différents éléments incluant un récipient 7 d'un liquide de désinsectisation 8, un récipient 9 d'un liquide de rinçage 11, une électrovanne à trois voies 12, une pompe 13, une buse de pulvérisation 14 ainsi qu'un réchauffeur 16 monté en amont de la buse, et un transformateur de courant 230 volt - 12 volt repéré par 17.The cabinet contains various elements including a container 7 of a disinsectant liquid 8, a container 9 of a rinsing liquid 11, a three-way solenoid valve 12, a pump 13, a spray nozzle 14 and a heater 16 mounted upstream of the nozzle, and a 230 volt - 12 volt current transformer identified by 17.
Le dispositif comprend en outre une unité de pilotage située dans la console 3 et reliée aux éléments de l'armoire 1 par les câbles 4 qui sont connectés à un bornier 18 monté dans l'armoire.The device further comprises a control unit located in the console 3 and connected to the elements of the cabinet 1 by the cables 4 which are connected to a terminal block 18 mounted in the cabinet.
Un premier tuyau 19 est connecté à l' électrovanne à trois voies 12 et plonge dans le récipient 7, un second tuyau 21 est connecté à l' électrovanne à trois voies 12 et plonge dans le récipient 9, et un troisième tuyau 22 relie la vanne à trois voies à la pompe 13.A first pipe 19 is connected to the three-way solenoid valve 12 and is immersed in the container 7, a second pipe 21 is connected to the three-way solenoid valve 12 and is immersed in the container 9, and a third pipe 22 connects the valve three-way pump 13.
Cette pompe 13 est elle-même reliée au réchauffeur par un autre tuyau non visible sur la figure, le réchauffeur étant lui-même relié à la buse 14. L'ensemble est alimenté en courant par le secteur. L'unité de commande comprend des moyens programmés pour piloter l' électrovanne afin de mette en communication la pompe 13 soit avec le récipient 7 contenant le liquide de désinsectisation 8, soit avec le récipient 9 contenant le liquide de rinçage 11.This pump 13 is itself connected to the heater by another pipe not visible in the figure, the heater being itself connected to the nozzle 14. The whole is powered by the sector. The control unit comprises programmed means for controlling the solenoid valve in order to communicate the pump 13 either with the container 7 containing the disinsectant liquid 8 or with the container 9 containing the rinsing liquid 11.
Comme visible dans la figure 3, la console 3 qui renferme l'unité de commande comprend sur sa face avant un interrupteur 23 de mise sous tension / hors tension du dispositif, et un bouton poussoir 24 permettant de lancer un cycle de désinsectisation.As shown in Figure 3, the console 3 which contains the control unit comprises on its front face a switch 23 for turning on / off the device, and a push button 24 to initiate a disinsectisation cycle.
Elle comprend également un premier voyant 26 qui est allumé lorsqu'un cycle est en cours, et un second voyant 27 qui s'allume si le niveau de liquide dans le récipient 7 ou 9 est insuffisant pour lancer un cycle.It also comprises a first indicator 26 which is lit when a cycle is in progress, and a second indicator 27 which lights up if the level of liquid in the container 7 or 9 is insufficient to initiate a cycle.
Lorsque l'utilisateur désire lancer un cycle de désinsectisation, il s'assure que le dispositif est sous tension, puis enfonce le bouton poussoir 24 de départ de cycle .When the user wishes to launch a disinsectisation cycle, he makes sure that the device is energized, then presses the push button 24 of the cycle start.
L'unité centrale enclenche une temporisation avant de lancer la phase de désinsectisation. Cette temporisation qui est réglable entre quatre minutes et trois heures permet à l'opérateur de quitter le local en toute sécurité avant le début de la désinsectisation.The central unit starts a delay before starting the disinsectisation phase. This time delay, which is adjustable between four minutes and three hours, allows the operator to leave the room safely before the start of the disinsection.
Une fois cette temporisation écouléem l' électrovanne 12 est pilotée par l'unité de commande pour mettre en communication le récipient 7 avec la pompe 13. Le réchauffeur 16 est alors mis sous tension et la pompe 13 est actionnée par l'unité de commande.Once this delay has elapsedem the solenoid valve 12 is controlled by the control unit to communicate the container 7 with the pump 13. The heater 16 is then energized and the pump 13 is actuated by the control unit.
Pendant une durée prédéterminée, le liquide de désinsectisation passe dans le réchauffeur et est éjecté par la buse 14 de manière à produire une fumée dans le local à désinsectiser. Le dispositif génère de la fumée, c'est-à-dire des particules en suspension : si un l'on place un écran face à la buse durant la phase de désinsectisation, cet écran reste sec.For a predetermined period, the disinsectant liquid passes into the heater and is ejected through the nozzle 14 so as to produce smoke in the room to be disinfected. The device generates smoke, that is to say particles in suspension: if a screen is placed facing the nozzle during the disinsectisation phase, this screen remains dry.
Une fois la durée prédéterminée de la phase de désinsectisation écoulée, l'unité de commande enclenche la phase de rinçage en pilotant l' électrovanne pour qu'elle mette la pompe 13 en communication avec le récipient 9 contenant le liquide de rinçage 11.Once the predetermined duration of the disinsection phase has elapsed, the control unit starts the rinsing phase by controlling the solenoid valve to put the pump 13 in communication with the container 9 containing the rinsing liquid 11.
Le liquide de rinçage traverse à son tour la pompe pour être éjecté par la buse, de manière à rincer cet ensemble de tubulures pendant une autre durée prédéterminée .The rinse liquid in turn passes through the pump to be ejected through the nozzle, thereby rinsing the tubing assembly for another predetermined period of time.
La durée de la phase de désinsectisation est enregistrée dans l'unité de commande. Cette durée est avantageusement configurable, par exemple en intervenant dans la console de commande, et en agissant sur une vis de réglage ou autre.The duration of the disinsectisation phase is recorded in the control unit. This duration is advantageously configurable, for example by intervening in the control console, and by acting on a set screw or other.
La durée de cette phase de désinsectisation est choisie en fonction du volume du local à traiter et du produit de désinsectisation qui est utilisé, puis elle est configurée une fois pour toutes lors de l'installation du dispositif selon l'invention.The duration of this disinsection phase is chosen as a function of the volume of the room to be treated and the disinsectant product that is used, then it is configured once and for all during the installation of the device according to the invention.
Afin d'optimiser le pouvoir de désinsectisation, la durée de la phase de désinsectisation est choisie pour produire un volume de fumée correspondant à trois fois le volume du local à désinsectiser.In order to optimize the power of disinsection, the duration of the disinsection phase is chosen to produce a volume of smoke corresponding to three times the volume of the premises to be disinfected.
En introduisant dans le local un volume de fumée significativement supérieur au volume du local, on crée ainsi une légère surpression durant le traitement, ce qui permet d'établir une circulation de la fumée, la fumée excédentaire étant éventuellement évacuée par les interstices de l'enceinte du local. Ceci permet d'établir durant le traitement une circulation de la fumée pour que celle-ci pénètre dans une plus grande quantité de coins et de recoins du local de manière à améliorer l'efficacité du traitement.By introducing into the room a volume of smoke significantly greater than the volume of the room, it creates a slight overpressure during the treatment, which allows to establish a flow of smoke, the excess smoke is eventually removed by the interstices of the local speaker. This makes it possible to establish during the treatment a flow of smoke so that it penetrates into a greater number of nooks and crannies of the room so as to improve the efficiency of the treatment.
Le choix de la durée de la phase de désinsectisation consiste à multiplier par trois le volume du local à traiter, à déterminer à partir des spécifications du produit de désinsectisation utilisé, le volume de produit nécessaire pour générer le volume de fumée ainsi trouvé.The choice of the duration of the disinsection phase consists in multiplying by three the volume of the room to be treated, to be determined from the specifications of the disinsectisation product used, the volume of product necessary to generate the volume of smoke thus found.
Ensuite, la durée de la phase de désinsectisation est déterminée pour éjecter par la buse la quantité de produit définie ci-dessus, en se basant sur le débit de la pompe.Then, the duration of the disinsectisation phase is determined to eject the amount of product defined above from the nozzle, based on the flow rate of the pump.
A titre d'exemple, la pompe du dispositif illustré sur les figures, en association avec le produit de désinsectisation utilisé permet de générer 100 mètres cubes de fumée par minute, ce qui permet de traiter en trois minutes un local de 100 mètres cubes.By way of example, the pump of the device illustrated in the figures, in association with the disinsectisation product used makes it possible to generate 100 cubic meters of smoke per minute, which makes it possible to treat a room of 100 cubic meters in three minutes.
Comme visible dans la figure 2, l'armoire 1 renferme encore une pompe de mélange repérée par 28 et qui est reliée au récipient 7 par deux tuyaux repérés par 29 et 31 plongeant chacun dans ce récipient 7.As can be seen in FIG. 2, the cabinet 1 still contains a mixing pump marked at 28 and which is connected to the container 7 by two pipes marked 29 and 31 each immersing in this receptacle 7.
Cette pompe est activée périodiquement par l'unité de commande, ce qui permet de brasser le liquide de désinsectisation pour éviter qu' il ne se stratifié pour être en mesure de déclencher un cycle de désinsectisation à tout moment.This pump is periodically activated by the control unit, which makes it possible to stir the disinsectant liquid to prevent it from being stratified in order to be able to trigger a disinsectisation cycle at any time.
L' invention apporte notamment les avantages suivants :The invention notably provides the following advantages:
Elle permet d'utiliser des produits de désinsectisation traditionnels ou proches des produits traditionnels tels que le liquide Λ 'Aquapaille' ' commercialisé par la société Bayer, et qui peut être réchauffé pour produire une fumée.It allows the use of traditional pest products or close to traditional products such as liquid Λ 'Aquapaille'' marketed by Bayer, which can be reheated to produce smoke.
Il est ainsi possible à chaque désinsectisation de tuer l'ensemble des insectes adultes rampants et volant, avec un produit ne contenant pas de bromure de méthyle.It is thus possible for each disinsection to kill all crawling and flying adult insects with a product that does not contain methyl bromide.
Grâce à son installation à demeure dans le local à traiter, l'utilisateur peut lui-même effectuer de manière simple la gestion de la désinsectisation. Avantageusement, celle-ci est réalisée toutes les deux à trois semaines, ce qui correspond à la durée pendant laquelle les larves d'insectes deviennent adultes.Thanks to its permanent installation in the room to be treated, the user can himself easily manage the disinsection. Advantageously, this is carried out every two to three weeks, which corresponds to the duration during which the larvae of insects become adults.
La console de commande distincte de l'armoire peut être placée sous cette armoire qui est quant à elle installée en hauteur dans une partie centrale du local pour assurer une diffusion optimale de la fumée. The control console separate from the cabinet can be placed under this cabinet, which is installed high up in a central part of the room to ensure optimal diffusion of the smoke.
