Description

JONCTION D'EXTREMITE ENTRE DEUX TUBES DE CIRCULATION DE FLUIDE ET REACTEUR EQUIPE D'UNE TELLE JONCTION  END CONNECTION BETWEEN TWO FLUID CIRCULATION TUBES AND REACTOR EQUIPPED WITH SUCH A JUNCTION
DOMAINE DE L'INVENTION L'invention concerne une jonction d'extrémité entre deux tubes de circulation de fluide ainsi qu'un réacteur, en particulier un photobioréacteur, équipé d'au moins une telle jonction. FIELD OF THE INVENTION The invention relates to an end junction between two fluid circulation tubes and a reactor, in particular a photobioreactor, equipped with at least one such junction.
Elle concerne plus particulièrement une jonction d'extrémité entre deux tubes de circulation de fluide formée de deux corps d'axes parallèles, lesdits corps comprenant chacun une face d'extrémité ouverte de raccordement à un tube et une deuxième face d'extrémité opposée. It relates more particularly to an end junction between two fluid circulation tubes formed of two bodies of parallel axes, said bodies each comprising an open end face of connection to a tube and a second opposite end face.
ART ANTÉRIEUR PRIOR ART
L'utilisation de photobioréacteur tubulaire pour la production de molécules d'intérêt destinées aux industries pharmaceutique, cosmétique ou agroalimentaire ou pour la culture de microorganismes, en particulier dans le domaine de l'aquaculture, s'est répandue ces dernières années. The use of tubular photobioreactor for the production of molecules of interest intended for the pharmaceutical, cosmetic or agri-food industries or for the cultivation of microorganisms, in particular in the field of aquaculture, has spread in recent years.
Ces photobioréacteurs tubulaires comprennent généralement au moins deux tubes parallèles verticaux reliés entre eux à chacune de leurs extrémités pour définir un espace clos à l'intérieur duquel un fluide circule. L'inconvénient majeur d'un tel réacteur est l'encrassement potentiel rapide des parois constitutives des tubes dudit réacteur. These tubular photobioreactors generally comprise at least two vertical parallel tubes interconnected at each of their ends to define a closed space within which a fluid flows. The major disadvantage of such a reactor is the potential rapid fouling of the constituent walls of the tubes of said reactor.
Pour éviter ou réduire le risque d'un tel encrassement, la génération et l'entretien d'un mouvement tourbillonnaire sont réalisés en connectant les tubes entre eux par des dispositifs de jonction qui permettent d'introduire le fluide liquide tangentiellement en entrée de la colonne formée par ledit tube et donc, de générer un mouvement tourbillonnaire. Un exemple d'un tel dispositif de jonction est décrit dans la demande de brevet EP-1 .632.562. To avoid or reduce the risk of such fouling, the generation and maintenance of a vortex movement are achieved by connecting the tubes together by junction devices that allow to introduce the liquid fluid tangentially at the entrance of the column formed by said tube and therefore, to generate a swirling motion. An example of such a junction device is described in patent application EP-1 632 562.

Comme mentionné ci-dessus, l'invention a pour objet une jonction 1 d'extrémité entre deux tubes 20 de circulation de fluide plus particulièrement appliquée à un réacteur 19 du type de celui représenté à la figure 1 . Ce réacteur comprend deux tubes 20 verticaux parallèles. Les extrémités supérieures des tubes sont reliées par une première jonction 1 d'extrémité et les extrémités inférieures des tubes sont reliées par une deuxième jonction d'extrémité qui peut être identique ou distincte de la première jonction d'extrémité. Dans l'exemple représenté, les deux jonctions d'extrémité sont identiques, entraînant une simplification du réacteur. As mentioned above, the invention relates to an end junction 1 between two fluid circulation tubes 20 more particularly applied to a reactor 19 of the type shown in FIG. This reactor comprises two parallel vertical tubes. The upper ends of the tubes are connected by a first end junction 1 and the lower ends of the tubes are connected by a second end junction which may be identical or distinct from the first end junction. In the example shown, the two end junctions are identical, resulting in a simplification of the reactor.
Chaque jonction 1 d'extrémité comprend un corps 2 cylindrique et un corps 3 cylindro-sphérique, c'est-à-dire comportant un tronçon cylindrique fermé à une extrémité par une calotte sphérique pour conférer à ladite face d'extrémité une forme bombée convexe à convexité tournée vers l'extérieur du tronçon cylindrique. La partie sphérique du corps cylindro-sphérique est donc formée par la face 7 d'extrémité avec cheminée, en forme générale d'hémisphère ou de calotte sphérique dudit corps. Le rayon de la partie sphérique peut être identique ou inférieur au rayon de la partie cylindrique du corps. Each end junction 1 comprises a cylindrical body 2 and a cylindrical-spherical body 3, that is to say having a cylindrical section closed at one end by a spherical cap to give said end face a convex convex shape with convexity turned towards the outside of the cylindrical section. The spherical portion of the cylindrical-spherical body is thus formed by the end face 7 with a chimney, in the general shape of hemisphere or spherical cap of said body. The radius of the spherical portion may be the same as or smaller than the radius of the cylindrical portion of the body.
Le corps 2 cylindrique et le corps 3 cylindro-sphérique s'étendent parallèlement entre eux et sont reliés l'un à l'autre par un passage 8. The cylindrical body 2 and the cylindrical-spherical body 3 extend parallel to each other and are connected to each other by a passage 8.
Le corps 2 cylindrique présente l'une de ses faces d'extrémité appelée première face d'extrémité qui est ouverte et qui sert au raccordement à un tube 20. Cette première face d'extrémité ouverte est représentée en 4 aux figures. L'autre face d'extrémité du corps 2 cylindrique représentée en 6 aux figures est, dans les exemples représentés, une face d'extrémité au moins partiellement fermée. En effet, cette face 6 d'extrémité est fermée par une surface plane de laquelle fait saillie une cheminée 13 axiale qui s'étend en saillie vers l'extérieur, depuis ladite face 6 d'extrémité. Cette cheminée 13 est dite axiale car elle est coaxiale au corps 2 cylindrique. Cette cheminée 13 peut être débouchante ou non débouchante. En variante, cette cheminée pourrait être supprimée, la face 6 d'extrémité étant dans ce cas fermée. The cylindrical body 2 has one of its end faces called the first end face which is open and which serves to connect to a tube 20. This first open end face is shown at 4 in the figures. The other end face of the cylindrical body 2 shown at 6 in the figures is, in the examples shown, an end face at least partially closed. Indeed, this end face 6 is closed by a flat surface from which projects an axial chimney 13 which projects outwardly from said end face 6. This fireplace 13 is so-called axial because it is coaxial with the cylindrical body 2. This chimney 13 may be emergent or non-emergent. Alternatively, this chimney could be removed, the end face 6 being in this case closed.
Le corps 3 cylindro-sphérique comprend, de manière similaire, une première face 5 d'extrémité ouverte de raccordement à un tube 20. Le raccordement entre tube et corps s'opère par emmanchement, tant au niveau du corps 2 cylindrique qu'au niveau du corps 3 cylindro-sphérique. The cylindro-spherical body 3 comprises, in a similar way, a first open end face 5 of connection to a tube 20. The connection between the tube and the body takes place by fitting, both at the level of the cylindrical body 2 and at the level of the cylindrical body 2. 3 cylindro-spherical body.
La face 7 d'extrémité opposée du corps 3 cylindro-sphérique, qui constitue la partie sphérique du corps, est munie d'une cheminée 14 axiale, c'est-à-dire d'axe confondu avec l'axe longitudinal du corps et s'étend en saillie vers l'extérieur depuis la face 7 d'extrémité. Comme mentionné ci-dessus, cette face 7 d'extrémité avec cheminée du corps 3 cylindro-sphérique qui correspond à la partie sphérique dudit corps est en forme générale d'hémisphère ou de calotte sphérique. En variante, la cheminée pourrait être supprimée. Chacune de ces cheminées, lorsqu'elle est présente, comme dans les exemples représentés, peut être débouchante ou non débouchante. Dans l'exemple représenté, la cheminée 13 du corps cylindrique est une cheminée débouchante, ouverte à son extrémité opposée à celle se raccordant au corps, et avec un diamètre d'ouverture inférieur à 2 mm, de préférence encore, inférieur à 1 mm. The opposite end face 7 of the cylindro-spherical body 3, which constitutes the spherical part of the body, is provided with an axial chimney 14, that is to say with an axis coinciding with the longitudinal axis of the body and extends outwardly from the end face 7. As mentioned above, this end face 7 with a chimney of the cylindro-spherical body 3 which corresponds to the spherical portion of said body is in the general shape of hemisphere or spherical cap. Alternatively, the chimney could be removed. Each of these chimneys, when present, as in the examples shown, may be open or not open. In the example shown, the chimney 13 of the cylindrical body is a chimney opening, open at its end opposite to that connecting to the body, and with an opening diameter of less than 2 mm, more preferably less than 1 mm.
Dans l'exemple représenté en particulier, le diamètre d'ouverture de la cheminée 13 du corps 2 cylindrique est égal à 1 mm. La cheminée 13 du corps cylindro-sphérique est non débouchante ou borgne. In the example shown in particular, the opening diameter of the stack 13 of the cylindrical body 2 is equal to 1 mm. The chimney 13 of the cylindro-spherical body is not open or blind.
Le passage 8, qui relie les corps cylindrique et cylindro-sphérique entre eux comprend deux flancs 9, 10 en regard et deux parois 1 1 , 12 de liaison. Les parois 1 1 , 12 de liaison forment respectivement le dessus et le dessous du passage 8 en position verticale des axes des corps cylindrique 2 et cylindro- sphérique 3. L'un des flancs, appelé premier flanc et représenté en 9 aux figures, tangente la partie cylindrique des deux corps. Il se présente sous forme d'un élément droit. L'autre flanc, appelé deuxième flanc et représenté en 10 aux figures, définit avec le premier flanc, une section de passage qui se rétrécit depuis le corps 3 cylindro-sphérique en direction du corps 2 cylindrique. Ainsi, le passage 8 présente une largeur prise suivant une direction perpendiculaire au premier flanc, comprise entre 10 et 30 mm, de préférence voisine de 30 mm côté extrémité du passage en liaison avec le corps cylindro-sphérique et une largeur comprise entre 10 et 20 mm, de préférence voisine de 15 mm côté extrémité du passage en liaison avec le corps cylindrique. The passage 8, which connects the cylindrical body and cylindrical-spherical between them comprises two sidewalls 9, 10 opposite and two walls 1 1, 12 connecting. The connecting walls 1 1, 12 respectively form the top and the bottom of the passage 8 in the vertical position of the axes of the cylindrical body 2 and the cylindrical spherical body 3. One of the flanks, called the first flank and shown at 9 in the figures, tangents the cylindrical portion of the two bodies. It is in the form of a straight element. The other sidewall, called the second sidewall and shown at 10 in the figures, defines with the first sidewall, a passage section which narrows from the cylindro-spherical body 3 towards the cylindrical body 2. Thus, the passage 8 has a width taken in a direction perpendicular to the first side, between 10 and 30 mm, preferably close to 30 mm end side of the passage in connection with the cylindrical-spherical body and a width of between 10 and 20 mm, preferably close to 15 mm end side of the passage in connection with the cylindrical body.
Ce deuxième flanc 10 est formé par une paroi courbe, comme illustré à la figure 7, avec une convexité de la paroi orientée vers le premier flanc 9. Ce deuxième flanc 10 tangente, dans sa zone de raccordement au corps cylindrique, un plan parallèle au premier flanc 9 et tangente, dans sa zone de raccordement au corps 3 cylindro-sphérique le diamètre du corps 3 cylindro- sphérique. La zone de raccordement du deuxième flanc 10 au corps 2 cylindrique est disposée dans un plan, parallèle au premier flanc, et écartée du premier flanc d'une distance au plus égale au rayon du cylindre formé par le corps 2 cylindrique. Dans l'exemple représenté, chaque paroi 1 1 , 12 de liaison est reliée à chacun des flancs par une zone courbe, pour éviter une accumulation des salissures. Ainsi, la paroi 1 1 de liaison formant le dessus du passage est reliée à chacun des flancs 9, 10 par une zone courbe représentée en 16 aux figures, tandis que la paroi 12 de liaison formant le dessous du passage est reliée à chacun des flancs 9, 10 par une zone courbe représentée en 15 aux figures. This second sidewall 10 is formed by a curved wall, as illustrated in FIG. 7, with a convexity of the wall oriented towards the first sidewall 9. This second sidewall tangent, in its zone of connection with the cylindrical body, a plane parallel to the first flank 9 and tangent, in its zone of connection to the body 3 cylindro-spherical the diameter of the body 3 cylindrospherical. The zone of connection of the second flank 10 to the cylindrical body 2 is disposed in a plane, parallel to the first flank, and spaced from the first flank by a distance at most equal to the radius of the cylinder formed by the cylindrical body 2. In the example shown, each connecting wall 1 1, 12 is connected to each of the flanks by a curved area, to prevent a build up of dirt. Thus, the connecting wall 1 1 forming the top of the passage is connected to each of the sidewalls 9, 10 by a curved zone shown at 16 in the figures, while the connecting wall 12 forming the underside of the passage is connected to each of the sidewalls. 9, 10 by a curved area shown at 15 in the figures.
De manière caractéristique à l'invention, les corps cylindrique 2 et cylindro- sphérique 3, le passage 8 et les cheminées 13 et 14, lorsqu'elles sont présentes, forment un ensemble monobloc, réalisé d'une seule pièce. Characteristically to the invention, the cylindrical body 2 and cylindrical spherical 3, the passage 8 and the chimneys 13 and 14, when present, form a one-piece assembly, made in one piece.
La jonction 1 d'extrémité peut ainsi être réalisée à l'aide des techniques de fabrication utilisées pour les pièces en matière de synthèse. En effet, cette pièce est en matière de synthèse de préférence en polyéthylène haute densité. The end junction 1 can thus be realized using the techniques of manufacturing used for parts in synthesis. Indeed, this piece is in synthesis material preferably high density polyethylene.
Dans le réacteur obtenu avec de telles jonctions 1 d'extrémité, les tubes 20 peuvent être comme illustré positionnés verticalement et le flux de fluide circule dans la jonction 1 d'extrémité placée à l'extrémité supérieure des tubes, comme dans la jonction d'extrémité placée à l'extrémité inférieure des tubes, depuis le corps cylindro-sphérique en direction du corps cylindrique. Au moins une alimentation en air est prévue en partie basse du réacteur, pour favoriser une agitation du fluide et limiter l'encrassement des tubes. En partie haute, l'ouverture ménagée dans l'une des cheminées peut permettre une évacuation d'air et du fluide par surverse. Le mouvement tourbillonnaire généré dans les tubes évite un encrassement trop rapide des tubes et permet une meilleure exposition du flux de fluide à la lumière. In the reactor obtained with such end junctions 1, the tubes 20 can be as illustrated positioned vertically and the flow of fluid flows in the end junction 1 placed at the upper end of the tubes, as in the junction of end placed at the lower end of the tubes, from the cylindrical-spherical body towards the cylindrical body. At least one air supply is provided in the lower part of the reactor, to promote agitation of the fluid and limit clogging of the tubes. In the upper part, the opening in one of the chimneys can allow an air outlet and fluid overflow. The swirling motion generated in the tubes prevents too rapid clogging of the tubes and allows a better exposure of the fluid flow to the light.
En variante, les tubes 20 peuvent être positionnés horizontalement. Alternatively, the tubes 20 may be positioned horizontally.
