Abstract

Apparatus for increasing the homogeneity of the mixture of fluids, e.g. petroleum products flowing together in a pipe. The apparatus operates by dividing the flow into multiple converging jets and comprises a tubular body (10) for insertion in the pipe. The tubular body (10) houses a cylindrical sheath (9) inside which two plates (21, 22) provided with perforations (23) define two inlet chambers (25, 26) between which the flow is distributed. The space (33) between the plates is partitioned by a plurality of partitions (36) which are substantially perpendicular to the axis of the sheath so as to constitute outlet cells in which jets from the perforations of the plates converge. Said outlet cells have openings (38) formed in the sheath for the lateral removal of the fluids which mix therein.

Description

La présente invention concerne un dispositif pour augmenter l'homogénéité d'un mélange de fluides circulant ensemble dans une canalisation. Par mélange il faut entendre la présence simultanée de plusieurs fluides, miscibles ou non-miscibles.The present invention relates to a device for increasing the homogeneity of a mixture of fluids circulating together in a pipeline. By mixing is meant the simultaneous presence of several fluids, miscible or immiscible.

L'invention s'applique notamment à l'homogénéisation d'un mélange d'eau et d'hydrocarbures liquides circulant dans une conduite ; cette homogénéisation est rendue nécessaire lorsqu'on souhaite mesurer avec précision la quantité d'eau dans le mélange.The invention applies in particular to the homogenization of a mixture of water and liquid hydrocarbons flowing in a pipe; this homogenization is made necessary when it is desired to accurately measure the amount of water in the mixture.

Il a déjà été proposé de fractionner l'écoulement venant de l'amont en une pluralité de jets convergents et de modifier la valeur du diamètre des jets.It has already been proposed to split the flow coming from upstream into a plurality of convergent jets and to modify the value of the diameter of the jets.

Dans ce type de dispositif, dont le schéma de principe fait l'objet de la figure 1 de la présente demande, et qui comprend une chambre à parois perforées 3 disposée au sein de la canalisation 2 dans lequel circulent les fluides de l'amont A vers l'aval B, les jets tels que a1 situés vers l'amont du mélangeur sont bien radiaux et donc convergents.In this type of device, the block diagram of which is the subject of FIG. 1 of the present application, and which comprises a chamber with perforated walls 3 arranged within the pipe 2 in which the fluids from upstream A circulate downstream B, the jets such as a1 located upstream of the mixer are well radial and therefore convergent.

Par contre, vers l'aval du mélangeur, les jets (a2, a3) sont perturbés par l'écoulement longitudinal qui s'instaure de l'amont vers l'aval dans la chambre 3.On the other hand, towards the downstream of the mixer, the jets (a2, a3) are disturbed by the longitudinal flow which is established from upstream to downstream in the chamber 3.

Il en résulte que la vitesse des jets a une composante radiale de plus en plus faible à mesure que l'on considère les jets situés de plus en plus vers l'aval ; les jets opposés ne se rencontrent plus et le mélange se fait mal.As a result, the speed of the jets has a radial component which becomes less and less as one considers the jets located more and more downstream; the opposite jets no longer meet and the mixing is bad.

Un but de l'invention est de définir un dispositif pour augmenter l'homogénéité du mélange de deux fluides, fondé sur le même principe de fractionnement des fluides en jets convergents, mais qui possède des performances accrues et une meilleure sécurité d'emploi pour toutes les valeurs de débit de l'écoulement considéré.An object of the invention is to define a device for increasing the homogeneity of the mixture of two fluids, based on the same principle of fractionation of fluids into convergent jets, but which has increased performance and better job security for all the flow values of the flow considered.

L'invention a pour objet un dispositif pour augmenter l'homogénéité du mélange de fluides circulant ensemble dans une canalisation, par fractionnement de l'écoulement en multiples jets convergents, caractérisé en ce qu'il comprend, inséré dans la canalisation une structure cylindrique comprenant un fourreau cylindrique à l'intérieur duquel deux plaques munies d'orifices définissent deux chambres entre lesquelles l'écoulement se partage, l'espace entre les plaques étant cloisonné par une pluralité de cloisons sensiblement perpendiculaires à l'axe du fourreau de manière à constituer des cellules dans lesquelles se dirigent des jets convergents venant des orifices des plaques, lesdites cellules possédant des ouvertures pratiquées dans le fourreau pour l'évacuation latérale des fluides qui se sont mélangés dans les cellules.The invention relates to a device for increasing the homogeneity of the mixture of fluids circulating together in a pipeline, by splitting the flow into multiple convergent jets, characterized in that it comprises, inserted into the pipeline a cylindrical structure comprising a cylindrical sheath inside which two plates provided with orifices define two chambers between which the flow is divided, the space between the plates being partitioned by a plurality of partitions substantially perpendicular to the axis of the sheath so as to constitute cells in which converging jets are directed coming from the orifices of the plates, said cells having openings made in the sheath for the lateral evacuation of the fluids which have mixed in the cells.

Avantageusement, les plaques font entre elles un angle compris entre 15 et 30 degrés ouvert vers l'aval, de façon à rendre plus uniformes les vitesses longitudinales dans les chambres et à améliorer l'écoulement à l'approche des plaques.Advantageously, the plates form an angle between them between 15 and 30 degrees open downstream, so as to make the longitudinal speeds in the chambers more uniform and to improve the flow when approaching the plates.

Dans un mode préféré de réalisation, le fourreau est disposé coulissant dans un premier conduit relié à la canalisation en amont, un second conduit de diamètre supérieur au premier conduit étant fixé à celui-ci et à la canalisation aval, l'écoulement des fluides mélangés s'effectuant dans la zone comprise entre le fourreau et la paroi interne du second conduit.In a preferred embodiment, the sleeve is slidably disposed in a first conduit connected to the upstream pipe, a second pipe of diameter greater than the first pipe being fixed to the latter and to the downstream pipe, the flow of the mixed fluids taking place in the area between the sheath and the internal wall of the second conduit.

En variante, le fourreau est muni d'un manchon coulissant dont le déplacement obture successivement les ouvertures du fourreau.Alternatively, the sheath is provided with a sliding sleeve, the displacement of which successively closes the openings of the sheath.

L'invention sera bien comprise par la description donnée ci-après d'un mode préféré de réalisation de l'invention, en référence au dessin annexé dans lequel :

  • - la figure 1 est une vue schématique expliquant l'art antérieur.
  • - la figure 2 est une vue en perspective partiellement arrachée d'un dispositif selon la présente invention.
  • - les figures 3 et 4 sont des vues en coupe selon les lignes III-III et IV-IV la figure 2.
  • - les figures 5 et 6 représentent le même dispositif dans diverses positions de fonctionnement.
The invention will be better understood from the description given below of a preferred embodiment of the invention, with reference to the appended drawing in which:
  • - Figure 1 is a schematic view explaining the prior art.
  • - Figure 2 is a partially cutaway perspective view of a device according to the present invention.
  • - Figures 3 and 4 are sectional views along lines III-III and IV-IV in Figure 2.
  • - Figures 5 and 6 show the same device in various operating positions.

Le dispositif représenté dans la figure 2 comprend un conduit amont 10 relié par une bride 11 à une canalisation amont 12 représentée partiellement en traits interrompus, et un conduit aval 15 relié par une bride 16 à une canalisation aval 17 représentée partiellement en traits interrompus.The device shown in FIG. 2 comprises an upstream conduit 10 connected by a flange 11 to an upstream pipe 12 shown partially in broken lines, and a downstream conduit 15 connected by a flange 16 to a downstream pipe 17 shown partially in broken lines.

Le but du dispositif est de mélanger intimement les fluides arrivant de l'amont pour obtenir en aval un mélange suffisamment homogène et stable pour, par exemple, effectuer des mesures significatives de la concentration de transport de l'un ou de plusieurs des fluides transportés.The purpose of the device is to intimately mix the fluids arriving from upstream to obtain downstream a sufficiently homogeneous and stable mixture to, for example, make significant measurements of the transport concentration of one or more of the fluids transported.

Les conduits 10 et 15 sont assemblés par des brides 13 et 14.The conduits 10 and 15 are assembled by flanges 13 and 14.

Le dispositif comprend une structure cylindrique disposée dans les conduits 10 et 15.The device comprises a cylindrical structure arranged in the conduits 10 and 15.

La structure cylindrique comprend un fourreau cylindrique 9 obturé à son extrémité aval et de diamètre inférieur au conduit 10 pour s'y loger ; à l'intérieur du fourreau sont disposées deux plaques perforées ou grilles, 21 et 22, planes, munies de perforations 23 ; ces deux plaques sont reliées de façon étanche au fond aval du fourreau et sont reliées entre elles à l'amont soit directement, soit par une tôle déflectrice 24. Par cette disposition deux chambres 25, 26 sont créées qui séparent l'écoulement amont en deux parties. Ensuite les fluides se divisent en multiples jets opposés représentés par les flèches f1 de la figure 3.The cylindrical structure comprises a cylindrical sheath 9 closed at its downstream end and with a diameter less than the duct 10 to accommodate it; inside the sheath are arranged two perforated plates or grids, 21 and 22, flat, provided with perforations 23; these two plates are tightly connected to the downstream bottom of the sheath and are connected to each other upstream either directly or by a deflector plate 24. By this arrangement two chambers 25, 26 are created which separate the upstream flow in two parts. Then the fluids divide into multiple opposite jets represented by the arrows f1 in FIG. 3.

Facultativement les deux chambres amont au-dessus et au-dessous des plaques perforées peuvent être divisées par des cloisons perpendiculaires 31 et 32 ; ces cloisons contribuent au maintien des plaques dans le fourreau 9.Optionally the two upstream chambers above and below the perforated plates can be divided by perpendicular partitions 31 and 32; these partitions contribute to maintaining the plates in the sheath 9.

Dans le cas qui est celui des figures les plaques perforées s'écartent vers l'aval d'un angle compris entre 15 et 30 degrés.In the case which is that of the figures, the perforated plates deviate downstream by an angle between 15 and 30 degrees.

Enfin, l'espace compris entre les deux plaques perforées est fractionné en multiples cellules 34 délimitées par les plaques perforées 21 et 22 et par des cloisons 36 perpendiculaires à l'axe général du fourreau.Finally, the space between the two perforated plates is divided into multiple cells 34 delimited by the perforated plates 21 and 22 and by partitions 36 perpendicular to the general axis of the sheath.

Les jets f1 qui convergent vers l'espace 33 compris entre les plaques, s'échappent latéralement par des ouvertures latérales 38 pratiquées dans le fourreau 9. Grâce à cette disposition, l'écoulement ne vient pas modifier la composante verticale de la vitesse des jets f1 et le mélange se fait aussi bien vers les zones aval du dispositif que vers les zones amont.The jets f1 which converge towards the space 33 included between the plates, escape laterally through lateral openings 38 made in the sleeve 9. Thanks to this arrangement, the flow does not come to modify the vertical component of the speed of the jets f1 and the mixing takes place both towards the downstream zones of the device and towards the upstream zones.

La structure qui vient d'être définie peut coulisser dans les conduits et dans ce cas, qui est celui des figures, son mouvement est assuré par des pistons 41 et 42 coulissant dans des cylindres 51 et 52 disposés de part et d'autre du conduit 10.The structure which has just been defined can slide in the conduits and in this case, which is that of the figures, its movement is provided by pistons 41 and 42 sliding in cylinders 51 and 52 arranged on either side of the duct 10.

Les tiges 61, 62 des pistons 41, 42 traversent les brides 13, 14 et sont terminées par des plots 71, 72 de fixation et de guidage du fourreau.The rods 61, 62 of the pistons 41, 42 pass through the flanges 13, 14 and are terminated by studs 71, 72 for fixing and guiding the sheath.

Le coulissement de la structure permet de régler le débit d'écoulement en obturant une ou plusieurs des cellules 34.The sliding of the structure makes it possible to adjust the flow rate by closing one or more of the cells 34.

Dans la figure 2, on observe qu'une cellule et demie est obturée. Dans la figure 5, toutes les cellules 34 sont obturées ; le dispositif se comporte alors comme une vanne fermée.In Figure 2, we see that a cell and a half is closed. In Figure 5, all cells 34 are closed; the device then behaves like a closed valve.

Dans la figure 6, au contraire, la structure mobile est repoussée complètement en amont ; l'écoulement se fait sans turbulence notable, mais sans perte importante de charge.In FIG. 6, on the contrary, the mobile structure is pushed back completely upstream; the flow takes place without significant turbulence, but without significant pressure drop.

En variante, non représentée, le fourreau 9 peut être fixe et le réglage du débit du mélangeur assuré par un manchon coulissant autour du fourreau.As a variant, not shown, the sleeve 9 can be fixed and the adjustment of the flow rate of the mixer ensured by a sliding sleeve around the sleeve.

L'invention s'applique notamment au mélange de produits pétroliers circulant dans une canalisation et qui comprennent une proportion d'eau qu'il est nécessaire de mesurer avec précision. Cette mesure ne peut être faite qu'après homogénéisation du mélange par passage dans le dispositif de l'invention.The invention applies in particular to the mixture of petroleum products circulating in a pipeline and which comprise a proportion of water which it is necessary to measure with precision. This measurement can only be made after homogenization of the mixture by passage through the device of the invention.
