Description

OzoneurOzonator

La présente invention concerne un ozoneur d'un nouveau type.The present invention relates to an ozonator of a new type.

Le procédé de production d'ozone connu repose sur le principe suivant : l'ozone est produit à partir d'oxygène pur ou contenu dans un gaz, par exemple l'air, cet oxygène passant dans un champ électrique créé entre deux électrodes mises sous haute tension. Ce procédé de production d'ozone par décharge électrique est très simple dans sa mise en oeuvre avec un réacteur de faible encombrement.The known ozone production process is based on the following principle: ozone is produced from pure oxygen or contained in a gas, for example air, this oxygen passing through an electric field created between two electrodes placed under high tension. This method of producing ozone by electrical discharge is very simple in its implementation with a compact reactor.

Par rapport à ce principe, les différences entre les dispositifs connus résident donc dans la conception du réacteur et du système de refroidissement. En ce qui concerne le réacteur, on distingue deux types de dispositifs, ceux qui utilisent les décharges alternatives haute tension, et ceux qui utilisent des décharges continues haute tension.Compared to this principle, the differences between the known devices therefore lie in the design of the reactor and of the cooling system. With regard to the reactor, there are two types of devices, those which use high voltage alternative discharges, and those which use continuous high voltage discharges.

Dans le cas de systèmes utilisant des décharges alternatives haute tension, le générateur d'ozone est alors un dispositif capacitif à deux diélectriques : le diélectrique solide recouvrant l'une et/ou l'autre électrodes et le gaz en écoulement. La géométrie des électrodes et la nature du diélectrique contribuent à différencier les différents systèmes dans leurs utilisations pratiques et dans leurs coûts d'investissement. Dans ce procédé de fabrication d'ozone, seule une partie relativement faible de 1' énergie électrique sert a la transformation de l'oxygène en ozone. La plus grande partie est dégradée sous forme de chaleur dans le milieu réactionnel et l'élévation de la température entraîne la dissociation de la molécule d'ozone formée, diminuant ainsi la production. Pour évacuer cette chaleur, on a recours à un refroidissement soit du réacteur lui même ou des électrodes, soit du gaz asséché qui sert à la production d'ozone.In the case of systems using high voltage alternative discharges, the ozone generator is then a capacitive device with two dielectrics: the solid dielectric covering one and / or the other electrodes and the flowing gas. The geometry of the electrodes and the nature of the dielectric help differentiate the different systems in their practical uses and in their investment costs. In this ozone manufacturing process, only a relatively small part of the electrical energy is used to transform oxygen into ozone. Most of it is degraded in the form of heat in the reaction medium and the rise in temperature causes the ozone molecule formed to dissociate, thereby reducing production. To dissipate this heat, recourse is had to cooling either of the reactor itself or of the electrodes, or of dry gas which is used for the production of ozone.

Les autres dispositifs connus utilisent des décharges continues haute tension. C'est le cas des dispositifs décrits dans les brevets français N° 77 209 78 (N° publication) et N° 78 278 78 (N° publication) qui concernent des ozoneurs fonctionnant sur ce principe issu des précipitateurs électrostatiques et utilisant la décharge couronne. La géométrie de 1 'ozoneur est tubulaire mais, en raison des dimensions géométriques pour obtenir une production cohérente, on aboutit à des champs d'application très réduits.The other known devices use high voltage continuous discharges. This is the case of the devices described in French patents N ° 77 209 78 (N ° publication) and N ° 78 278 78 (N ° publication) which concern ozonizers operating on this principle resulting from electrostatic precipitators and using corona discharge . The geometry of the ozonator is tubular but, because of the geometrical dimensions to obtain a coherent production, this leads to very reduced fields of application.

Le but de la présente invention est donc de proposer un ozoneur d'un nouveau type qui puisse être utilisé dans un grand nombre d'applications et soit, en raison de sa conception, aisément interchangeable, nettoyable, démontable et d'un faible coût tout en permettant une production d'ozone variable que ce soit en quantité ou en concentration.The object of the present invention is therefore to propose an ozonator of a new type which can be used in a large number of applications and either, because of its design, easily interchangeable, cleanable, dismountable and of low cost while by allowing a variable production of ozone either in quantity or in concentration.

L'invention concerne à cet effet un ozoneur du type comportant une électrode négative ou positive, une électrode reliée à la masse, un corps dOzoneur éventuellement formé par l'une des électrodes, un fluide gazeux circulant axialement dans l'espace laissé libre entre les deux électrodes et traversant de ce fait le champs électrique généralement continu appliqué entre lesdites électrodes, de telle sorte que les décharges couronne générées provoquent à partir de l'oxygène du gaz la formation d'ozone, caractérisé en ce que le corps de l'ozoneur est coiffé à chacune de ses extrémités munies d'embouts appropriés de pièces terminales qui, en position verrouillée correspondant à une position dans laquelle elles sont maintenues en contact étanche aux extrémités du corps de 1 Ozoneur, assurent le raccordement à la haute tension de 1 'ensemble et 1 'amenée ou 1'évacuation du fluide gazeux circulant à l'intérieur du corps de l'ozoneur.To this end, the invention relates to an ozonator of the type comprising a negative or positive electrode, an electrode connected to ground, an ozone body possibly formed by one of the electrodes, a gaseous fluid circulating axially in the space left free between the two electrodes and thereby passing through the generally continuous electric field applied between said electrodes, so that the corona discharges generated cause the formation of ozone from the oxygen of the gas, characterized in that the body of the ozonator is capped at each of its ends provided with suitable end pieces of end pieces which, in the locked position corresponding to a position in which they are kept in sealed contact at the ends of the body of 1 ozonator, ensure the connection to the high voltage of 1 ' together and the inlet or outlet of the gaseous fluid circulating inside the body of the ozonator.

Selon une forme de réalisation préférée de l'invention, 1 'ozoneur est du type fil-cylindre et comporte un corps d'ozoneur constitué d'une électrode interne telle qu'un fil entouré coaxialement par une deuxième électrode dite électrode externe généralement de forme tubulaire réalisée en un matériau conducteur, l'électrode interne étant reliée à la haute tension continue positive ou négative, l'électrode externe étant reliée à la masse, le fluide gazeux circulant axialement dans 1 ' espace libre entre les deux électrodes et traversant de ce fait le champ électrique continu appliqué entre l'électrode interne et la surface interne de la paroi de révolution de l'électrode externe.According to a preferred embodiment of the invention, the ozonator is of the wire-cylinder type and comprises an ozonizer body consisting of an internal electrode such as a wire surrounded coaxially by a second electrode called an external electrode generally of shape tubular made of a conductive material, the internal electrode being connected to the positive or negative direct high voltage, the external electrode being connected to ground, the gaseous fluid circulating axially in the free space between the two electrodes and passing through it makes the continuous electric field applied between the internal electrode and the internal surface of the wall of revolution of the external electrode.

La simplicité des électrodes permet la réalisation d'un appareil modulaire, facile d'emploi, peu exigeant en entretien et peu coûteux. En outre, il offre une parfaite sécurité puisque le déverrouillage du dispositif commande l'arrêt automatique de l'application de la haute tension et éventuellement la fermeture de l'arrivée du gaz. En outre, l'ensemble des pièces étant isolé, cet appareil peut être manipulé sans danger y compris lorsque la haute tension est appliquée.The simplicity of the electrodes allows the creation of a modular device, easy to use, low maintenance and inexpensive. In addition, it offers perfect security since the unlocking of the device controls the automatic stopping of the application of the high voltage and possibly the closing of the gas supply. In addition, all the parts being isolated, this device can be handled without danger even when high voltage is applied.

D'autres caractéristiques et avantages de l'invention apparaîtront encore à la lecture de la description qui suit en référence aux dessins joints, lesquels description et dessins sont donnés surtout à titre d'exemples. Dans ces dessins : la figure 1 représente une vue en coupe d'un ozoneur avec un corps d'ozoneur en position verrouillée correspondant à la position de fonctionnement ; la figure 2 représente une vue en coupe de l'ozoneur de la figure 1 en position déverrouillée ; la figure 3 représente une vue en coupe du corps de 1'ozoneur de la figure 1 ; la figure 4 représente une vue en coupe d'une partie de 1'embout du corps de 1'ozoneur ; et les figures 5 et 6 représentent respectivement en coupe, les pièces terminales mobile d'alimentation en gaz et fixe de sortie de gaz et d'alimentation en haute tension continue.Other characteristics and advantages of the invention will become apparent on reading the description which follows with reference to the accompanying drawings, which description and drawings are given mainly by way of examples. In these drawings: FIG. 1 represents a sectional view of an ozonator with an ozonator body in the locked position corresponding to the operating position; 2 shows a sectional view of the ozonator of Figure 1 in the unlocked position; Figure 3 shows a sectional view of the body of the ozonator of Figure 1; Figure 4 shows a sectional view of part of the end cap of the ozonator body; and Figures 5 and 6 show respectively in section, the movable end pieces of gas supply and fixed gas outlet and DC high voltage supply.

Conformément aux figures 1 et 2, 1'ozoneur est un ozoneur du type fil-cylindre comportant un corps d'ozoneur constitué d'une part par une électrode interne telle qu'un fil, d'autre part par une électrode externe de forme tubulaire. L'électrode interne est, dans le cas représenté aux figures 1 ou 2, un fil métallique de faible diamètre 1 réalisé en un matériau bon conducteur d'électricité à température de fusion élevée, soudable, par exemple un alliage de nickel et de chrome.In accordance with FIGS. 1 and 2, the ozonator is an ozonator of the wire-cylinder type comprising an ozonator body constituted on the one hand by an internal electrode such as a wire, on the other hand by an external electrode of tubular shape . The internal electrode is, in the case shown in FIGS. 1 or 2, a small diameter metallic wire 1 made of a material which is a good conductor of electricity at high melting temperature, which can be welded, for example an alloy of nickel and chromium.

L'électrode externe est quant à elle constituée d'un tube cylindrique ou d'un tube a ailettes 2 réalisé également en un matériau bon conducteur et peu oxydable. Cette électrode entoure coaxiale ent l'électrode interne 1. L'électrode interne 1 est destinée à être alimentée par une haute tension continue négative ou positive. L'électrode externe 2 est quant à elle reliée à la masse. La longueur du corps ainsi constitué est généralement comprise entre 5 et 40 cm. Outre ces deux électrodes, le corps de 1'ozoneur comporte à ses deux extrémités deux embouts isolants 3 (selon figure 3) résistants à l'ozone, par exemple en PVC ou en PTFE, venant en appui sur l'électrode externe 2. Ces embouts sont munis d'au moins un perçage traversant 5 (selon figures 3 ou 4) qui permet d'une part le passage du fluide gazeux devant circuler dans l'espace vide laissé entre l'électrode interne 1 et l'électrode externe 2, d'autre part la sortie de l'électrode interne 1 hors du corps de 1 'ozoneur et son maintien dans une position parfaitement centrée par rapport à l'électrode externe 2. De ce fait, le principe pointe/plan à la base de cette configuration est respecté de manière certaine et ce sur toute la longueur du corps de l'ozoneur. En effet, cette électrode interne 1 constituée par un fil est munie à chacune des extrémités de renflements 6 et 7 (figure 3) qui permettent, en venant en appui sur la face de l'embout isolant 3 opposée à celle en contact avec le corps de 1Ozoneur, de maintenir une tension correcte du fil. Ce renflement 6 ou 7 peut bien évidemment être également constitué par des pièces métalliques indépendantes sur lesquelles le fil constitutif de l'électrode interne 1 est soudé. Grâce au passage du fil à travers le perçage traversant 5 de l'embout 3 qui sert de guide-axe, on est certain que le fil 1 conservera une position correcte à l'intérieur de l'électrode externe. Ce fil, étant soumis à des variations de longueurs en raison du fait qu'il est parcouru par une haute tension, est muni à au moins une de ses extrémités de moyens de rappel tels qu'un ressort 8 disposé entre le renflement 7 (ou 6) et la surface d'appui dudit renflement sur 1'embout 3 de manière à pouvoir corriger les variations de longueur dudit fil et à assurer une tension toujours correcte du fil 1. On notera qu'à l'une des extrémités du fil, le renflement 6 fait saillie hors de l'embout 3 de manière à venir en contact avec un élément métallique 15 (figure 1 ou 2) relié à la haute tension disposé à l'intérieur d'une pièce 11 coiffant l'embout 3. Les embouts 3, conformément à ce qui est représenté à la figure 4, comportent, outre ce perçage traversant 5 permettant le passage du fil 1, plusieurs trous 4, par exemple quatre, disposés circonferenciellement par rapport à ce dernier et sécants à celui-ci. Ces trous 4 permettent en fait le passage dans une direction quelconque du fluide gazeux circulant dans l'espace laissé libre entre l'électrode interne 1 et l'électrode externe 2. Bien évidemment, on aurait pu imaginer d'autres modes de réalisation de l'invention dans lesquels ces perçages auraient été réduits à un seul et même perçage à la fois pour le passage du fluide gazeux et la sortie de l'électrode interne. Le corps de 1 Ozoneur est, en position verrouillée, inséré dans des pièces terminales 10 et 11 représentées aux figures 5 et 6 qui coiffent de manière étanche les embouts 3 obturant au moins partiellement les extrémités du corps de l'ozoneur. L'insertion étanche est réalisée au moyen d'un joint torique 9 présentant bien évidemment un bonne tenue à l'ozone et venant en appui sur une portée conique des pièces terminales 10 et 11. Ces pièces terminales 10 et 11 sont fabriquées en matière isolante, l'une d'entre elles étant équipée d'un contact métallique 15 relié à la haute tension par des éléments désignés par 13 et 14. Ces pièces terminales 10 et 11 sont équipées de cavités de manière à venir coiffer au moins une portion de l'embout 3 fermant le corps de 1'ozoneur tout en laissant un espace libre entre l'extrémité de l'embout et le fond de la cavité de la pièce terminale 10, 11. L'intérêt de cet espace libre sera expliqué ci-après.The external electrode, for its part, consists of a cylindrical tube or a fin tube 2 also made of a good conductive material and not very oxidizable. This electrode coaxially surrounds the internal electrode 1. The internal electrode 1 is intended to be supplied by a high negative or positive direct voltage. The external electrode 2 is in turn connected to ground. The length of the body thus formed is generally between 5 and 40 cm. In addition to these two electrodes, the ozonator body has at its two ends two insulating tips 3 (according to FIG. 3) resistant to ozone, for example PVC or PTFE, bearing on the external electrode 2. These nozzles are provided with at least one through bore 5 (according to FIGS. 3 or 4) which allows on the one hand the passage of the gaseous fluid which must circulate in the empty space left between the internal electrode 1 and the external electrode 2, on the other hand, the output of the internal electrode 1 from the body of the ozonator and its maintenance in a perfectly centered position relative to the external electrode 2. From this fact, the point / plane principle at the base of this configuration is respected with certainty and this over the entire length of the ozonator body. In fact, this internal electrode 1 constituted by a wire is provided at each of the ends with bulges 6 and 7 (FIG. 3) which allow, by coming to bear on the face of the insulating tip 3 opposite to that in contact with the body of 1 Ozonator, to maintain a correct tension of the wire. This bulge 6 or 7 can obviously also consist of independent metal parts on which the wire constituting the internal electrode 1 is welded. Thanks to the passage of the wire through the through hole 5 of the endpiece 3 which serves as an axis guide, it is certain that the wire 1 will maintain a correct position inside the external electrode. This wire, being subjected to length variations due to the fact that it is traversed by a high voltage, is provided at at least one of its ends with return means such as a spring 8 disposed between the bulge 7 (or 6) and the bearing surface of said bulge on the end piece 3 so as to be able to correct the variations in length of said wire and to ensure always correct tension of the wire 1. It will be noted that at one of the ends of the wire, the bulge 6 projects from the end piece 3 so as to come into contact with a metal element 15 (FIG. 1 or 2) connected to the high voltage disposed inside a part 11 covering the end piece. end pieces 3, in accordance with what is shown in FIG. 4, comprise, in addition to this through bore 5 allowing the passage of the wire 1, several holes 4, for example four, arranged circumferentially relative to the latter and intersecting therewith. These holes 4 in fact allow the passage in any direction of the gaseous fluid circulating in the space left free between the internal electrode 1 and the external electrode 2. Obviously, one could have imagined other embodiments of the invention in which these holes would have been reduced to a single hole both for the passage of the gaseous fluid and the output of the internal electrode. The body of 1 ozonator is, in the locked position, inserted into end pieces 10 and 11 shown in FIGS. 5 and 6 which seal the end pieces 3 at least partially closing the ends of the ozonator body. The sealed insertion is carried out by means of an O-ring 9 obviously exhibiting good resistance to ozone and coming to bear on a conical bearing surface of the end pieces 10 and 11. These end pieces 10 and 11 are made of insulating material , one of them being equipped with a metal contact 15 connected to the high voltage by elements designated by 13 and 14. These end pieces 10 and 11 are equipped with cavities so as to come over at least a portion of the nozzle 3 closing the body of the ozonator while leaving a free space between the end of the nozzle and the bottom of the cavity of the end piece 10, 11. The advantage of this free space will be explained below. after.

Ces pièces terminales 10 et 11 sont animées l'une par rapport à l'autre d'un mouvement relatif. Dans l'exemple représenté, ces pièces sont montées solidaires d'un support constitué par une plaque métallique 18, l'une des pièces 11 étant fixe, l'autre pièce 10 étant montée mobile sur ce support. Pour ce faire, une rainure de guidage est ménagée sur le support de manière à ce que la pièce terminale 10 coulisse à l'intérieur de cette rainure pour pouvoir se rapprocher et/ou s'écarter de la pièce 11. Ce mouvement de coulissement de la pièce 10 est commandé par un organe d' actionnement tel qu'un levier 17 monté à pivotement sur ladite plaque 18 et relié au moyen d'un bras également monté à pivotement à la fois sur le levier 17 et sur la pièce mobile 10 pour actionner ladite pièce. Chacune des pièces terminales 10, 11 est équipée d'une canalisation 12 sur 1 'une de ses faces latérales permettant 1 ' amenée ou la sortie de gaz.These end pieces 10 and 11 are animated relative to each other by a relative movement. In the example shown, these parts are mounted integral with a support constituted by a metal plate 18, one of the parts 11 being fixed, the other part 10 being movably mounted on this support. To do this, a guide groove is formed on the support so that the end piece 10 slides inside this groove in order to be able to approach and / or move away from the piece 11. This sliding movement of the part 10 is controlled by an actuating member such as a lever 17 pivotally mounted on said plate 18 and connected by means of an arm also pivotally mounted both on the lever 17 and on the movable part 10 for operate said part. Each of the end pieces 10, 11 is fitted with a pipe 12 on one of its side faces allowing the gas to be brought in or out.

Dans l'exemple représenté, l'entrée de gaz se fait au niveau de la pièce 10 par la canalisation 12 reliée à une source de fluide gazeux et la sortie de gaz se fait au niveau de la canalisation 12 de la pièce 11. En général, l'entrée du fluide gazeux se fait à l'extrémité du corps de 1 Ozoneur opposée à celle reliée à la haute tension. La pièce terminale 11 fixe comporte en effet des moyens d'alimentation en haute tension grâce aux éléments 13 et 14 reliés à une source de haute tension, ces éléments 13 et 14 étant eux-mêmes solidaires d'un contact métallique 15 qui, en position verrouillée de l'ensemble, vient en contact avec le renflement 6 de l'électrode interne 1. Grâce à ce contact de pression, l'électrode interne 1 est alimentée en haute tension. Quant à l'électrode externe, elle est reliée à la masse au moyen d'un clip 16 monté solidaire de la plaque métallique support 18. En position déverrouillée telle que représentée à la figure 2, le levier 17 est maintenu écarté de la plaque support 18 et la pièce terminale 10 est écartée de la pièce terminale 11. De ce fait, le corps de 1 Ozoneur peut aisément être enlevé, pour pouvoir être nettoyé, changé, etc.In the example shown, the gas inlet is at the level of the part 10 by the line 12 connected to a source of gaseous fluid and the gas outlet is at the level of the line 12 of the part 11. In general , the entry of the fluid gas is done at the end of the body of 1 ozonator opposite to that connected to high voltage. The fixed end piece 11 in fact comprises high voltage supply means thanks to the elements 13 and 14 connected to a high voltage source, these elements 13 and 14 being themselves integral with a metal contact 15 which, in position locked to the assembly, comes into contact with the bulge 6 of the internal electrode 1. Thanks to this pressure contact, the internal electrode 1 is supplied with high voltage. As for the external electrode, it is connected to earth by means of a clip 16 mounted integral with the metal support plate 18. In the unlocked position as shown in FIG. 2, the lever 17 is kept apart from the support plate 18 and the end piece 10 is moved away from the end piece 11. Therefore, the body of the ozone generator can easily be removed, so that it can be cleaned, changed, etc.

On peut imaginer également de modifier l'organe d' actionnement constitué ici par un levier 17 de manière à pouvoir remplacer ce corps d'ozoneur par un corps de n'importe quelle dimension grâce à un organe d' actionnement qui permettrait l'immobilisation de la pièce terminale 10 en plusieurs positions. En position verrouillée au contraire, conformément à la position représentée à la figure 1 , les contacts électriques sont établis entre l'extrémité de l'électrode interne 1 constituée par un renflement 6 et les contacts métalliques 15 de la pièce terminale 11 de telle sorte que 1 ' ozoneur est alimenté en haute tension et l'alimentation en air s'effectue par l'intermédiaire de la canalisation 12 reliée à une source appropriée. Grâce au fait qu'en position verrouillée, un espace est laissé libre dans la cavité de la pièce terminale destinée à recevoir l'embout du corps de 1'ozoneur, le fluide gazeux provenant de la source de gaz peut librement circuler des pièces terminales vers le corps de 1'ozoneur. En effet, dans cette cavité débouchent d'une part la canalisation d'amenée ou de sortie de gaz 12 de la pièce terminale 10 ou 11, d'autre part le perçage 4 pour le passage du gaz de l'embout 3, grâce à quoi on aboutit alors à un passage aisé du fluide gazeux de la canalisation 12 vers l'intérieur du corps de l'électrode de 1'ozoneur et une mise en communication de l'ensemble. Ce gaz ressort ensuite par l'autre canalisation 12.One can also imagine modifying the actuating member constituted here by a lever 17 so as to be able to replace this ozonator body by a body of any size thanks to an actuating member which would allow the immobilization of the end piece 10 in several positions. In the locked position, on the contrary, in accordance with the position shown in FIG. 1, the electrical contacts are established between the end of the internal electrode 1 constituted by a bulge 6 and the metal contacts 15 of the end piece 11 so that 1 ozonator is supplied with high voltage and the air supply takes place via the pipe 12 connected to an appropriate source. Thanks to the fact that in the locked position, a space is left free in the cavity of the end piece intended to receive the nozzle of the body of the ozonator, the gaseous fluid coming from the gas source can freely circulate from the end pieces to body of the ozonator. Indeed, in this cavity open on the one hand the gas supply or outlet pipe 12 of the end piece 10 or 11, on the other hand the bore 4 for the passage of gas from the nozzle 3, thanks to which leads to a easy passage of the gaseous fluid from the pipe 12 towards the inside of the body of the ozonator electrode and communication of the assembly. This gas then leaves through the other pipe 12.

Bien évidemment, l'électrode négative ou positive et l'électrode reliée à la masse ainsi que le corps d'ozoneur peuvent affecter toute autre forme.Obviously, the negative or positive electrode and the electrode connected to ground as well as the ozonator body can affect any other form.

L'intérêt de ce dispositif est notamment lié à l'absence de risque en ce qui concerne son utilisation. En effet, bien que reliées à la haute tension, l'ensemble des pièces qui sont utilisées sont isolées et donc de ce fait, l'ensemble de l'appareil peut être manipulé y compris lorsqu'il est en fonctionnement. En position verrouillée, par simple commande du passage de la position verrouillée à la position déverrouillée, on commande l'arrêt automatique de l'application de la haute tension à la fois par rupture des contacts entre le corps de 1 'ozoneur et les pièces terminales et également éventuellement au moyen d'un relais supplémentaire qui commande 1 'arrêt de la source haute tension. On peut également commander la fermeture de l'arrivée du gaz toujours uniquement par 1 ' actionnement du levier 17.The advantage of this device is notably linked to the absence of risk with regard to its use. Indeed, although connected to high voltage, all of the parts that are used are isolated and therefore therefore, the entire device can be handled even when it is in operation. In the locked position, by simply controlling the passage from the locked position to the unlocked position, the automatic application of the high voltage is automatically stopped by breaking the contacts between the body of the ozonator and the terminal parts. and also optionally by means of an additional relay which controls the stopping of the high voltage source. It is also possible to control the closing of the gas supply always only by actuating the lever 17.

Ce dispositif présente en outre l'avantage de ne pas avoir à manipuler les sources de gaz et les moyens d'amenée ou d'évacuation du gaz. En outre, en raison de la simplicité des pièces constitutives du corps de l'ozoneur, pièces qui sont généralement identiques, amovibles et interchangeables telles que les embouts 3, la fabrication est facilitée, ce qui diminue les coûts. En outre, le fait que le corps de 1 'ozoneur soit amovible permet une maintenance et une réparation aisées de l'ensemble. Enfin, on peut également imaginer une configuration dans laquelle les corps dOzoneur sont placés en parallèle ou en série et, au moment de l'utilisation, des pièces terminales, également montées en parallèle, viennent obturer simultanément plusieurs corps dOzoneurs permettant un fonctionnement en parallèle ou en série de 1 ' ensemble pour obtenir une production plus importante d'ozone.This device also has the advantage of not having to manipulate the gas sources and the means of supplying or discharging the gas. In addition, due to the simplicity of the constituent parts of the body of the ozonator, parts which are generally identical, removable and interchangeable such as the end pieces 3, the manufacture is facilitated, which reduces costs. In addition, the fact that the body of the ozonator is removable allows easy maintenance and repair of the assembly. Finally, one can also imagine a configuration in which the ozone bodies are placed in parallel or in series and, at the time of use, end pieces, also mounted in parallel, seal several ozone bodies simultaneously allowing operation in parallel or in series of the set for obtain a higher production of ozone.

Bien évidemment, les applications de ce type d'ozoneur sont nombreuses : aseptisation, stérilisation, etc. Obviously, the applications of this type of ozonator are numerous: sanitization, sterilization, etc.
