Description

La présente invention concerne les installations de mise en contact d'un liquide avec un gaz, et concerne particulièrement les réfrigérants atmosphériques ou tours de réfrigération, pourvue d'un dispositif de garnissage à travers lequel le liquide tombe sous l'effet de la gravité et le gaz passe à contre-courant du liquide. Les installations de mise en contact d'un liquide avec un gaz comportent une chambre ou cheminée dans laquelle est installé le dispositif de garnissage. De tels dispositifs peuvent être constitués d'un assemblage de feuilles de ruissellement, généralement profilées.The present invention relates to installations for bringing a liquid into contact with a gas, and particularly relates to atmospheric refrigerants or cooling towers, provided with a packing device through which the liquid falls under the effect of gravity and the gas flows against the liquid. Installations for bringing a liquid into contact with a gas include a chamber or chimney in which the packing device is installed. Such devices may consist of an assembly of runoff sheets, generally profiled.

L'invention se rapporte à un dispositif de garnissage à feuilles de telles installations, ainsi qu'aux feuilles dont est constitué un tel dispositif.The invention relates to a device for filling sheets of such installations, as well as to the sheets of which such a device is made.

De tels assemblages sont notamment décrits dans les brevets FR-2.183.704 (DE-C-2.322.683) (US-3.830.684), FR-­2.263.808 (DE-C-2.508.722) (GB-1.495.788), EP-B-28.545 (US-­4.344.899) et FR-2.557.472 (US-4.581.183) (DE.3.447.895).Such assemblies are described in particular in patents FR-2,183,704 (DE-C-2,322,683) (US-3,830,684), FR-2,263.808 (DE-C-2,508,722) (GB-1,495. 788), EP-B-28.545 (US-4.344.899) and FR-2.557.472 (US-4.581.183) (DE.3.447.895).

Les feuilles de ruissellement décrites par exemple dans EP-28.545 et FR-A-2.557.472 comportent, dans une direction parallèle aux crêtes des ondulations, c'est-à-dire verticalement lorsque la feuille est en service, un nombre pair de zones successives d'extension égale suivant cette direction mais qui diffèrent entre elles par l'amplitude des ondulations. En suivant la ligne de crête des ondulations, on distingue au moins une paire de zones constituée d'une zone à ondulations de première amplitude et d'une zone à ondulations de plus faible amplitude ou, à la limite, d'amplitude nulle, qui sont réunies entre elles par une zone de transition. Les paquets de garnissage sont constitués par juxtaposition de feuilles de ruissellement identiques placées alternativement dans un sens et dans le sens inverse défini par une rotation de la feuille de 180° autour d'un axe approprié qui est fonction de la géométrie de la feuille, et en particulier, les ondulations et des points de contacts prévus dans les deux sortes de zones d'ondulations.The runoff sheets described for example in EP-28,545 and FR-A-2,557,472 comprise, in a direction parallel to the crests of the undulations, that is to say vertically when the sheet is in use, an even number of zones successive of equal extension in this direction but which differ between them by the amplitude of the undulations. By following the ridge crest line, at least one pair of zones is distinguished, consisting of a ripple zone of first amplitude and a ripple zone of lower amplitude or, at the limit, of zero amplitude, which are joined together by a transition zone. The packing packages are formed by juxtaposition of identical fill sheets placed alternately in one direction and in the direction inverse defined by a rotation of the sheet of 180 ° around an appropriate axis which is a function of the geometry of the sheet, and in particular, the undulations and contact points provided in the two kinds of undulation zones.

La fabrication de ces feuilles de ruissellement a lieu à partir de bandes de longueurs indéterminées.The manufacture of these runoff sheets takes place from strips of indefinite lengths.

Etant donné que les zones d'ondulations différentes séparées entre elles par une zone de transition se suivent verticalement lorsque les feuilles sont en place dans le paquet de garnissage en service, l'inversion des ondulations d'une zone à l'autre donne lieu à un effet de chicane particulièrement sensible à l'encrassement au niveau de la zone de transition.Since the zones of different corrugations separated from each other by a transition zone follow each other vertically when the sheets are in place in the packing pack in service, the inversion of the corrugations from one zone to another gives rise to a chicane effect which is particularly sensitive to fouling in the transition zone.

Les chenaux ainsi formés ont une allure tortueuse qui ne facilite pas leur entretien.The channels thus formed have a tortuous appearance which does not facilitate their maintenance.

L'encrassement peut provenir de matières en suspension, en cas de refroidissement d'eau sale, souillée ou simplement impure. De plus, les réfrigérants atmosphériques généralement traversés par de l'eau tiède aérée sont particulièrement propices au développement de divers microorganismes, notamment de bactéries et d'algues. Non seulement ces microorganismes, particulièrement les algues, peuvent boucher les chenaux par eux-mêmes, mais en plus ils peuvent fixer les fines matières en suspension dans l'eau, telles les particules de limon ou de sable.The fouling can come from suspended matter, when dirty, dirty or simply impure water cools. In addition, atmospheric refrigerants generally crossed by warm aerated water are particularly favorable for the development of various microorganisms, in particular bacteria and algae. Not only can these microorganisms, particularly algae, clog the channels by themselves, but they can also fix fine materials suspended in the water, such as silt or sand particles.

D'autre part, généralement, la fabrication des feuilles a lieu par déroulement de bandes dans le sens de la longueur des paquets de garnissage, transversalement aux lignes de crêtes des ondulations. Dans ce cas, la largeur de la bande et la hauteur des feuilles en service sont limitées par la largeur de l'outil de formage. Il est alors nécessaire d'empiler deux ou plusieurs paquets de garnissage pour atteindre la hauteur requise pour les dispositifs de garnissage dans les réfrigérants atmosphériques. La position relative des paquets est, dans ce cas, peu précise par suite de leur faible rigidité, non seulement au montage mais également sous l'effet de dilatation thermique et de la turbulence de l'eau et de l'air. Il en résulte que les chenaux d'un paquet de garnissage ne correspondent pas à ceux des paquets contigus inférieur ou supérieur. C'est une autre cause de formation d'étranglements à l'écoulement de l'eau et de l'air donnant lieu à la rétention de matières en suspension et à des conditions propices au développement de microorganismes.On the other hand, generally, the manufacture of the sheets takes place by unrolling strips in the direction of the length of the filling packages, transverse to the crest lines of the corrugations. In this case, the width of the strip and the height of the sheets in use are limited by the width of the forming tool. It is then necessary to stack two or more packets of packing to reach the height required for the packing devices in atmospheric refrigerants. The relative position of the packages is, in this case, imprecise due to their low rigidity, not only during assembly but also under the effect of thermal expansion and water and air turbulence. As a result, the channels of a lining package do not match those of the adjoining lower or upper packages. This is another cause of the formation of chokes in the flow of water and air, giving rise to the retention of suspended matter and to conditions favorable to the development of microorganisms.

La présente invention vise à remédier aux inconvénients précités des dispositifs de garnissage de la technique antérieure.The present invention aims to remedy the aforementioned drawbacks of the lining devices of the prior art.

A cet effet, il est prévu, selon l'invention, une bande pour feuilles de ruissellement pour dispositif de garnissage d'installation de mise en contact d'un liquide et d'un gaz à contre-courant, dont la largeur est déterminée et dont la longueur est indéterminée, profilée par défilement dans le sens de cette longueur dans un outil de profilage correspondant, dont la largeur correspond à celle de la bande, caractérisée en ce qu'elle comprend sur sa largeur deux zones d'égale largeur, l'une fortement ondulée et l'autre faiblement ondulée de même pas, sans discontinuité du pas à la transition entre les deux zones, pourvues chacune de bossages d'entretoisement situés en saillies sur les crêtes des ondulations sur ces deux faces et espacés suivant la longueur de la bande et symétriquement disposés par rapport à la ligne médiane séparant les deux zones et en ce que le plan moyen de la bande dans sa zone faiblement ondulée est parallèle au plan moyen de la bande dans sa zone fortement ondulée et est décalé d'un distance telle que les sommets de tous les bossages d'une des deux faces de la bande soient dans un même plan.To this end, there is provided, according to the invention, a strip for run-off sheets for a lining device for an installation for bringing a liquid and a gas in counter-current contact, the width of which is determined and whose length is indefinite, profiled by scrolling in the direction of this length in a corresponding profiling tool, whose width corresponds to that of the strip, characterized in that it comprises over its width two zones of equal width, l '' one strongly wavy and the other slightly wavy of the same pitch, without discontinuity of the pitch at the transition between the two zones, each provided with bracing bosses projecting from the crests of the corrugations on these two faces and spaced along the length of the strip and symmetrically arranged with respect to the median line separating the two zones and in that the mean plane of the strip in its weakly wavy zone is parallel to the mean plane of the strip in its strongly wavy zone and is offset by a distance such that the vertices of all the bosses on one of the two faces of the strip are in the same plane.

En variante, au lieu d'avoir une zone faiblement ondulée, la bande peut comporter une zone plate. Dans ce cas, les bossages d'entretoisement sont situés, dans la zone plate, symétriquement à ceux de la zone ondulée, les bossages qui se correspondant étant en saillie du même côté de l'épaisseur de la feuille. Dans ce cas également, le plan de la zone plate est parallèle au plan moyen de la feuille dans sa zone ondulée et est décalé d'une distance telle que les sommets de tous les bossages d'une des deux faces de la bande soient dans un même plan.Alternatively, instead of having a slightly wavy area, the strip may include a flat area. In this case, the spacer bosses are located, in the flat area, symmetrically to those of the corrugated area, the bosses which correspond being projecting on the same side of the thickness of the sheet. In this case also, the plane of the flat area is parallel to the mean plane of the sheet in its wavy area and is offset by a distance such that the vertices of all the bosses on one of the two faces of the strip are in the same plane.

A partir de cette bande, on découpe des feuilles de ruissellement en forme de rectangle comportant, suivant un premier côté du rectangle, deux zones d'égale largeur, l'une fortement ondulée, l'autre faiblement ondulée ou, à la limite, plate. Ces feuilles présentent les caractéristiques de bandes décrites ci-dessus avec la précision que l'autre second côté du rectangle des feuilles définit la hauteur des feuilles en service et que les bossages d'entretoisement sont espacés suivant ce second côté.From this strip, we cut runoff sheets in the shape of a rectangle comprising, along a first side of the rectangle, two zones of equal width, one strongly wavy, the other slightly wavy or, ultimately, flat . These sheets have the characteristics of strips described above with the precision that the other second side of the rectangle of the sheets defines the height of the sheets in service and that the bracing bosses are spaced along this second side.

Lesdites feuilles de ruissellement sont obtenues par découpe de la bande perpendiculairement à la longueur de celle-­ci, la largeur de la bande définissant le côté horizontal ou base de la feuille en service et la longueur de coupon définissant la hauteur de la feuille en service.Said run-off sheets are obtained by cutting the strip perpendicular to the length thereof, the width of the strip defining the horizontal side or base of the sheet in use and the length of coupon defining the height of the sheet in use.

Selon l'invention, un dispositif de garnissage d'installation de mise en contact d'un liquide et d'un gaz à contre-courant comporte des paquets de garnissage constitués de feuilles de ruissellement identiques telles que décrites ci-­dessus, la hauteur d'un paquet de garnissage étant égale à la hauteur d'une feuille en service et la largeur d'un paquet de garnissage étant égale au côté horizontal ou base d'une feuille en service. Dans les paquets de garnissage, les feuilles sont juxtaposées les unes aux autres par l'intermédiaire de leurs bossages d'entroisement, l'une dans un premier sens et la suivante dans un autre sens défini par une rotation de 180° du premier sens autour de la ligne médiane séparant les deux zones. Ces paquets de garnissage sont généralement formés d'un nombre pair de feuilles de ruissellement, soudées ou collées les unes aux autres suivant leurs bossages en contact mutuel. Lesdits paquets possèdent ainsi six faces d'appui planes, quatre étant constituées par les tranches ou épaisseurs de feuilles et les deux autres par les plans précités contenant les sommets plats des bossages externes des feuilles extérieures.According to the invention, a device for lining an installation for contacting a liquid and a counter-current gas comprises lining packages made up of identical run-off sheets as described above, the height d a packing pack being equal to the height of a sheet in use and the width of a packing pack being equal to the horizontal or base side of a sheet in use. In the packing packages, the sheets are juxtaposed to each other by means of their interlacing bosses, one in a first direction and the next in another direction defined by a rotation of 180 ° from the first direction around of the center line separating the two areas. These packing packages are generally formed of an even number of runoff sheets, welded or glued to each other according to their bosses in mutual contact. Said packages thus have six planar bearing faces, four being formed by the edges or thicknesses of sheets and the other two by the aforementioned planes containing the flat tops of the external bosses of the outer sheets.

Dans ces différents figures les mêmes notations de référence désignent les mêmes éléments.In these different figures, the same reference notations designate the same elements.

Sur la figure 1, on a représenté en plan une feuille 2 de ruissellement en forme de rectangle comportant un premier côté 3 et un second côté 4 lequel définit la hauteur de la feuille en service. Suivant son premier côté 3, la feuille comporte deux zones d'égale largeur, l'une ondulée 5, l'autre plate 6, pourvues de bossages d'entretoisement 7 situés, dans la zone ondulée 5 sur les crêtes 8 des ondulations des deux faces de la feuille.In Figure 1, there is shown in plan a sheet 2 of runoff in the shape of a rectangle having a first side 3 and a second side 4 which defines the height of the sheet in use. On its first side 3, the sheet has two zones of equal width, one wavy 5, the other flat 6, provided with bracing bosses 7 located, in the wavy zone 5 on the ridges 8 of the undulations of the two sides of the sheet.

Les bossages 7 sont espacés suivant le côté 4 du rectangle c'est-à-dire dans la direction des lignes de crête 8 des ondulations et ceux de la zone plate 6 sont situés symétriquement à ceux de la zone ondulée 5 par rapport à la ligne médiane 9 séparant les deux zones. Les bossages qui se correspondent sont en saillie du même côté de la feuille 2. Le plan de la zone plate 6 est parallèle au plan moyen 10 (figure 2) de la feuille dans sa zone ondulée 5 et est décalé de celui-ci d'une distance telle que les sommets de tous les bossages 7 d'une des faces de la feuille soient dans un même plan.The bosses 7 are spaced along the side 4 of the rectangle, that is to say in the direction of the crest lines 8 of the corrugations and those of the flat zone 6 are located symmetrically to those of the corrugated zone 5 with respect to the line median 9 separating the two zones. The bosses which correspond are projecting from the same side of the sheet 2. The plane of the flat area 6 is parallel to the mean plane 10 (FIG. 2) of the sheet in its wavy area 5 and is offset from it by a distance such that the vertices of all the bosses 7 of one of the faces of the sheet are in the same plane.

Les feuilles de ruissellement 2 sont par exemple fabriquées à partir de bandes en polymère organique tel que le chlorure de polyvinyle par des procédés connus, tels que le thermoformage sous vide, selon ces processus semi-continus où la bande défile par saccade (d'où le caractère semi-continu) à travers une presse pourvue des moules de profilage.The run-off sheets 2 are for example made from strips of organic polymer such as polyvinyl chloride by known methods, such as vacuum thermoforming, according to these semi-continuous processes where the strip passes by saccade (hence semi-continuous character) through a press provided with profiling molds.

La feuille 2 est obtenue par découpe de la bande perpendiculairement à la longueur de la bande, la largeur de la bande définissant le côté horizontal ou base 3 de la feuille en service tandis que la longueur du coupon définit la hauteur 4 de la feuille en service. Sur le dessin, cette hauteur est interrompue pour exprimer son caractère non limitatif.The sheet 2 is obtained by cutting the strip perpendicular to the length of the strip, the width of the strip defining the horizontal side or base 3 of the sheet in use while the length of the coupon defines the height 4 of the sheet in use . In the drawing, this height is interrupted to express its non-limiting nature.

Les bossages 7 ont tous la même hauteur, telle que sur l'un des deux côtés de la bande, le plan 10a défini par la surface extérieure de la zone plate 6 soit tangent aux crêtes 8 des ondulations de la zone ondulée 5.The bosses 7 all have the same height, such that on one of the two sides of the strip, the plane 10a defined by the outer surface of the flat area 6 is tangent to the crests 8 of the corrugations of the corrugated area 5.

Comme représenté sur les figures 2, 3A et 4C, les ondulations ont un profil arrondi d'allure sinusoïdale de pas constant 26. Sur la figure 3B, on voit que les bossages 7 sont à tête plate. Par ailleurs, la feuille est pourvue d'ondulations secondaires ou striages 11 mieux visibles sur la figure 3C et la figure 3D qui ont dans ce cas-ci, un profil à gradins (figure 3D). Ces ondulations secondaires 11 sont perpendiculaires aux ondulations principales, sur toute la surface des deux zones 5 et 6 à l'exception de celle des bossages d'entretoisement 7.As shown in FIGS. 2, 3A and 4C, the corrugations have a rounded profile with a sinusoidal shape of constant pitch 26. In FIG. 3B, it can be seen that the bosses 7 are with flat heads. Furthermore, the sheet is provided with secondary corrugations or striations 11 which are better visible in FIG. 3C and in FIG. 3D which in this case have a stepped profile (FIG. 3D). These secondary undulations 11 are perpendicular to the main undulations, over the entire surface of the two zones 5 and 6 with the exception of that of the bracing bosses 7.

Les ondulations principales peuvent, en variante, avoir un profil anguleux.The main undulations can, as a variant, have an angular profile.

Dans sa moitié supérieure, la feuille 2 est pourvue d'au moins une paire de méplats 12 aux pourtours renforcés, alignés suivant le côté 3 de la feuille de part et d'autre de la ligne médiane 9 séparant les deux zones 5 et 6 et à égale distance de cette ligne. Les figures 4A et 4B représentent ces méplats à plus grande échelle respectivement dans la zone ondulée (coupe E-­E) et dans la zone plate (coupe F-F).In its upper half, the sheet 2 is provided with at least one pair of flats 12 with reinforced edges, aligned along the side 3 of the sheet on either side of the center line 9 separating the two zones 5 and 6 and equidistant from this line. FIGS. 4A and 4B show these flats on a larger scale respectively in the corrugated area (section E-E) and in the flat area (section FF).

La feuille représentée provient d'une bande dans laquelle les paires de méplats sont disposées suivant la longueur de la bande à intervalles égaux à la plus petite hauteur prévue pour les paquets de garnissage.The sheet shown comes from a strip in which the pairs of flats are arranged along the length of the strip at intervals equal to the smallest height provided for the packing packs.

Lorsqu'on désire suspendre un paquet de garnissage, constitué de telles feuilles, on découpe les méplats de la rangée supérieure pour former ainsi une paire de trous alignés de part et d'autre de la ligne médiane 9 séparant les deux zones 5 et 6 et à égale distance de cette ligne. Les renforcements des méplats sont destinés à reduire les déformations lors de la suspension des paquets de garnissage.When it is desired to suspend a packet of filling, made up of such sheets, the flats of the upper row are cut to thereby form a pair of holes aligned on either side of the center line 9 separating the two zones 5 and 6 and equidistant from this line. The reinforcements of the flats are intended to reduce the deformations during the suspension of the packing packages.

Les paquets de garnissage sont constitués de feuilles de ruissellement 2 identiques telles que décrites ci-dessus. La hauteur d'un paquet de garnissage est égale à la hauteur 4 d'une feuille en service tandis que la largeur du paquet de garnissage est égale à la base 3 de la feuille. Dans ce paquet de garnissage, les feuilles sont juxtaposées les unes aux autres par l'intermédiaire de leurs bossages d'entretoisement 7 et collées ou soudées entre elles sur tous ou certains de leurs bossages, l'une dans un premier sens et la suivante dans un autre sens défini par une rotation de 180° du premier sens autour de la ligne médiane 9 séparant les deux zones. Les paquets de garnissage ainsi constitués possèdent six faces d'appui planes, quatre étant constituées par les tranches ou épaisseurs des feuilles et les deux autres par les plans précités contenant les sommets plats des bossages 7 externes des feuilles extérieures. Un tel paquet de garnissage désigné 1 est représenté en coupe sur la figure 2.The packing packages consist of identical runoff sheets 2 as described above. The height of a packing pack is equal to the height 4 of a sheet in use while the width of the packing pack is equal to the base 3 of the sheet. In this packing package, the sheets are juxtaposed to each other by means of their bracing bosses 7 and glued or welded together on all or some of their bosses, one in a first direction and the next in another direction defined by a 180 ° rotation of the first direction around the center line 9 separating the two zones. The lining packets thus formed have six flat bearing faces, four being formed by the edges or thicknesses of the sheets and the other two by the aforementioned planes containing the flat tops of the bosses 7 of the outer sheets. Such a packing package designated 1 is shown in section in FIG. 2.

Il n'y a pas de superposition de paquets de garnissage pour constituer le dispositif de garnissage.There is no overlapping of packing packets to constitute the packing device.

Ainsi qu'on le voit, les chenaux 15 ainsi formés dans le paquet de garnissage sont dépourvus de recoins, étranglements et aspérités. De plus, étant d'une seule venue, ils sont parfaitement rectilignes. Il en résulte une faible rétention des matières en suspension dans l'eau. Le paquet de garnissage est peu propice au développement d'algues et microorganismes divers tout en étant d'un nettoyage aisé.As can be seen, the channels 15 thus formed in the lining package are free of recesses, throttles and roughness. In addition, being of a single coming, they are perfectly straight. This results in poor retention of the suspended matter in the water. The packing package is not very conducive to the development of algae and various microorganisms while being easy to clean.

D'autre part, la géométrie des feuilles, également illustrée sur la figure 2, facilite leur stockage et transport à faible encombrement, toutes les feuilles se présentant dans le même sens, sans entretoisement, garantit une très faible déformation des feuilles sous le poids de la pile ainsi qu'une bonne stabilité des paquets de feuilles ainsi que des paquets de garnissage grâce au fait que les sommets des bossages sont situés dans un même plan.On the other hand, the geometry of the sheets, also illustrated in FIG. 2, facilitates their storage and transport in a small footprint, all the sheets being in the same direction, without bracing, guarantees very little deformation of the sheets under the weight of the stack and good stability of the sheet packets as well as the packing packets thanks to the fact that the tops of the bosses are located in the same plane.

Il est bien entendu que l'invention n'est pas limitée aux détails repris ci-dessus.It is understood that the invention is not limited to the details given above.
