Description
CHAMBRE DE MELANGE ET DISPOSITIF DE PULVERISATION COMPORTANT UNE TELLEMIXING CHAMBER AND SPRAY DEVICE COMPRISING SUCH
CHAMBREBEDROOM
La presente invention concerne une chambre permettant le melange d'un liquide avec un gaz, notamment integree a un dispositif permettant la pulverisation du melange. On connait une chambre de melange liquide - gaz pour pulverisateur qui s'etend selon une direction longitudinale, qui est delimitee par une enceinte, et qui comprend une ouverture d'entree pour 1'introduction du liquide situee a une premiere extremite longitudinale, des orifices pour 1'introduction du gaz, et une ouverture de sortie pour l'evacuation du melange liquide - gaz situee a la deuxieme extremite longitudinale. The present invention relates to a chamber for mixing a liquid with a gas, in particular integrated in a device for spraying the mixture. It is known a liquid-gas mixing chamber for sprayers which extends in a longitudinal direction, which is delimited by an enclosure, and which comprises an inlet opening for the introduction of the liquid located at a first longitudinal end, orifices. for introducing the gas, and an outlet opening for evacuating the liquid-gas mixture located at the second longitudinal end.
Cependant afin d'avoir une pulverisation efficace du melange, it est necessaire d'avoir une energie mecanique importante. Ainsi, en general, afin de compenser les pertes de charges se produisant dans 1'enceinte et les autres dispositifs associes permettant la pulverisation, le liquide est introduit avec une pression comprise entre 10 et 30 bars, ce qui a un cout. De plus, le liquide (et le melange) a une vitesse eleve, et, afin d'eviter toute usure rapide de 1'enceinte et des autres dispositifs associes, le liquide ne peut pas etre charge avec des particules ayant une granulometrie importante (a partir de 0,25 mm). Par ailleurs, afin d'eviter une separation precoce du liquide et du gaz, notamment clans le cas oil le gaz est de la vapeur d'eau, par condensation sur la surface interne de 1'enceinte, le gaz est introduit avec une pression superieure a 6 bars, ce qui entralne une forte consommation du gaz (le rapport de la masse du gaz sur la masse du liquide est souvent superieure a 0,3), ce qui a un cont. However in order to have an effective spraying of the mixture, it is necessary to have a significant mechanical energy. Thus, in general, in order to compensate for the pressure losses occurring in the enclosure and other associated devices for spraying, the liquid is introduced with a pressure of between 10 and 30 bar, which has a cost. In addition, the liquid (and the mixture) has a high velocity, and in order to avoid rapid wear of the enclosure and other associated devices, the liquid can not be charged with particles having a large particle size (a). from 0.25 mm). Furthermore, in order to avoid early separation of the liquid and the gas, especially in the case where the gas is water vapor, by condensation on the inner surface of the enclosure, the gas is introduced with a higher pressure. at 6 bars, which leads to a high consumption of gas (the ratio of the mass of the gas to the mass of the liquid is often greater than 0.3), which has a cont.
2 2894854 La presente invention vise a realiser une chambre de melange pouvant etre utilisee notamment clans un dispositif de pulverisation ne presentant pas les inconvenients precites.The present invention aims to achieve a mixing chamber that can be used in particular in a spraying device does not have the aforementioned drawbacks.
5 Selon 1'invention, les orifices d'introduction du gaz sont realises dans 1'enceinte et sont disposes de sorte que le gaz forme un film empechant tout contact entre le liquide et 1'enceinte et se melange avec le liquide a 1'interieur de 1'espace delimite par le film.According to the invention, the gas introduction ports are made in the enclosure and are arranged so that the gas forms a film preventing any contact between the liquid and the enclosure and mixes with the liquid inside. of the space delimited by the film.
10 Par cette disposition particuliere des orifices d'introduction du gaz permettant la formation d'un film gazeux, le melange liquide - gaz se fait a 1' interieur de cette game gazeuse, sans utilisation de composant mecanique supplementaire, ce qui permet de considerablement 15 reduire les pertes de charge, et de charger le liquide avec des particules relativement importantes (ayant une granulometrie superieure a plusieurs millimetres). En outre, comme le melange n'est pas en contact avec 1'enceinte, la separation precoce est considerablement 20 reduite. Par ailleurs, le melange obtenu clans la chambre de combustion est d'une telle qualite que, dans le cas of it comprend de 1'eau (provenant par exemple de la vapeur d'eau comprise dans le gaz), c'est une emulsion. D'autres particularites et avantages apparaitront dans 25 la description detaillee de deux modes de realisation particuliers donnes a titre d'exemple non limitatif et illustres dans les dessins annexes dans lesquels La figure 1 est une vue en coupe schematique d'un premier dispositif de pulverisation munie d'une chambre de 30 melange conforme a la presente invention, et La figure 2 est une vu similaire a la figure 1 d'un second dispositif de pulverisation.By this particular arrangement of the gas introduction ports allowing the formation of a gaseous film, the liquid-gas mixture is made within this gaseous game, without the use of additional mechanical component, which allows for considerably reduce the pressure drop, and charge the liquid with relatively large particles (having a particle size greater than several millimeters). In addition, since the mixture is not in contact with the enclosure, the early separation is considerably reduced. Furthermore, the mixture obtained in the combustion chamber is of such a quality that, in the case of it comprises water (from, for example, water vapor contained in the gas), it is an emulsion . Other particularities and advantages will appear in the detailed description of two particular embodiments given by way of nonlimiting example and illustrated in the accompanying drawings in which FIG. 1 is a schematic sectional view of a first spraying device. equipped with a mixing chamber according to the present invention, and Figure 2 is a view similar to Figure 1 of a second spraying device.
3 2894854 Un dispositif de pulverisation 1 comprend une chambre de melange 2 Bans laquelle est realisee un melange liquide - gaz 3. Dans les presents mode de realisation, le dispositif de pulverisation 1 est integre a un bruleur, le 5 liquide 4 etant un combustible liquide, et le gaz 5 pouvant titre de 1'air, du gaz combustible, de la vapeur d'eau ou un melange d'au moms deux de ces elements. La chambre de melange 2 s'etend selon une direction longitudinale 6, et est delimitee par une enceinte 7 qui clans le present 10 exemple, est de forme cylindrique. La chambre de melange 2 comprend une ouverture d'entree 8 qui est situee a une premiere extremite longitudinale et qui permet 1'introduction du liquide 4. Dans les presents mode de realisation, 1'alimentation de la 15 chambre de melange 2 en liquide est realisee par un organe d'introduction 9 qui est relie a 1'ouverture d'entree 8 par au moms une conduite d'introduction 10 (en 1'occurrence par une conduite 10). La chambre de melange 2 comprend une ouverture de 20 sortie 11 qui est situee a la deuxieme extremite longitudinale et qui permet 1'evacuation du melange liquide - gaz 3. Dans les presents mode de realisation, un organe d'ejection 12 est relie a 1'ouverture de sortie 11 et comprend au moms une conduite de sortie 13 permettant la 25 pulverisation du melange a sa sortie. Dans le premier mode de realisation, 1'organe d'ejection 12 ne comprend qu'une conduite de sortie 13 qui est de forme cylindrique et qui est orientee selon la direction longitudinale 6. Dans le second mode de realisation, 1'organe d'ejection 12 comprend 30 deux conduites de sortie 13 qui sont de forme cylindrique, qui sont orientees de sorte que leur axe directeur 16 fasse un angle 17 avec la direction longitudinale 6 et qui sont disposees de fagon diametralement opposees.A spraying device 1 comprises a mixing chamber 2 in which a liquid-gas mixture 3 is produced. In the present embodiment, the spraying device 1 is integrated with a burner, the liquid 4 being a liquid fuel. and the gas being air, fuel gas, steam or a mixture of at least two of these elements. The mixing chamber 2 extends in a longitudinal direction 6, and is delimited by an enclosure 7 which in this example is of cylindrical shape. The mixing chamber 2 comprises an inlet opening 8 which is located at a first longitudinal end and which allows the introduction of the liquid 4. In the present embodiments, the supply of the mixing chamber 2 with liquid is performed by an introduction member 9 which is connected to the inlet opening 8 by at least one introduction line 10 (in this case via a pipe 10). The mixing chamber 2 comprises an outlet opening 11 which is located at the second longitudinal end and which permits the evacuation of the liquid-gas mixture 3. In the present embodiment, an ejection member 12 is connected to the outlet opening 11 and comprises at least one outlet line 13 for spraying the mixture at its outlet. In the first embodiment, the ejection member 12 comprises only one outlet line 13 which is cylindrical in shape and which is oriented in the longitudinal direction 6. In the second embodiment, the organ of ejection 12 comprises two outlet ducts 13 which are of cylindrical shape, which are oriented so that their directing axis 16 makes an angle 17 with the longitudinal direction 6 and which are arranged diametrically opposed.
4 2894854 La chambre de melange 2 comprend des orifices 14 qui permettent 1'introduction du gaz 5 et qui sont realises clans 1'enceinte 7 et la traversent. Ces orifices 14 sont disposes de sorte que le gaz 5, d'une part, forme un 5 film 15 empechant le liquide 4 de circuler contre 1'enceinte 7, et, d'autre part, se melange avec le liquide 4 a 1'interieur de 1'espace delimite par le film 15. Dans les presents modes de realisation, les orifices 14 d'introduction du gaz sont formes par 10 1'enceinte 7 qui est en un materiau poreux, c'est-a-dire permeable au gaz 5. De preference, afin d'ameliorer 1'efficacite de la separation du liquide 4 de 1'enceinte 7 par le film 15, 1'enceinte 7 est rectiligne et s'etend selon la direction 15 longitudinale 6. De meme, 1'ouverture d'entree 8 ainsi que la conduite d'introduction 10 sont orientees de sorte que le liquide 4 circule clans la chambre de melange 2 selon la direction longitudinale 6. Pour les memes raisons, les orifices 14 d'introduction du gaz sont disposes de fagon a 20 permettre une repartition la plus uniforme possible du gaz le long de la surface interne de 1'enceinte 7, tant longitudinalement que perpendiculairement a la direction longitudinale : ici, 1'integralite de 1'enceinte 7 est faite en une matiere permeable au gaz 5 (par exemple en 25 metal fritte). En outre, du fait de la nature des orifices 14, la direction du gaz 5 a leur sortie est perpendiculaire a la direction longitudinale 6. De plus, en sortie de la (des) conduite(s) de sortie 13, le melange 3 sort sous forme pulverisee, sans 30 quill soit necessaire que le dispositif de pulverisation 1 comprenne des organes disposes dans le flux du liquide 4 et du melange 3 pour realiser la pulverisation.The mixing chamber 2 comprises orifices 14 which allow the introduction of the gas 5 and which are produced in the chamber 7 and pass through it. These orifices 14 are arranged so that the gas 5, on the one hand, forms a film 15 preventing the liquid 4 from circulating against the chamber 7, and, on the other hand, mixes with the liquid 4 to 1 '. In the present embodiments, the gas introduction orifices 14 are formed by the enclosure 7 which is made of a porous material, that is to say permeable to 5. Preferably, in order to improve the efficiency of the separation of the liquid 4 from the enclosure 7 by the film 15, the enclosure 7 is rectilinear and extends in the longitudinal direction 6. Similarly, 1 8 and the introduction pipe 10 are oriented so that the liquid 4 flows in the mixing chamber 2 in the longitudinal direction 6. For the same reasons, the orifices 14 for introducing the gas are arranged in order to allow the gas to be distributed as evenly as possible along the inner surface of the enclosure 7, both longitudinally and Only perpendicular to the longitudinal direction: here, the entirety of the enclosure 7 is made of a gas permeable material 5 (for example sintered metal). In addition, because of the nature of the orifices 14, the direction of the gas 5 at their outlet is perpendicular to the longitudinal direction 6. Moreover, at the outlet of the outlet line (s) 13, the mixture 3 exits In powdered form, it is necessary that the spraying device 1 comprises organs arranged in the flow of the liquid 4 and the mixture 3 to carry out the spraying.
5 2894854 Ainsi, les avantages d'une telle chambre de melange 2 et d'un tel dispositif de pulverisation 1 sont nombreux. Le liquide 4 et le melange 3 ne viennent pas contact avec la chambre de melange 2, de ce fait le liquide 4 (et donc le 5 melange 5) peut contenir des particules dont la granulometrie est superieure a quelques millimetres. De ce fait egalement, le liquide 4 ne subit pas de perte de charge importante et it peut donc titre delivre a une pression bien plus faible que daps les pulverisateurs 10 classique : elle peut titre comprise entre 0,1 et 2 bar, et, de preference, entre 0,2 et 1 bar. Par ailleurs, toujours pour la meme raison, une fois le melange 3 realise, la separation precoce du liquide 4 et du gaz 5 est limitee, et, de ce fait, le gaz 5 peut titre delivre a une pression 15 bien plus faible que clans les pulverisateurs classique : elle peut titre comprise entre 0,1 et 3 bar, et, de preference, entre 0,2 et 1 bar (pour un liquide 4 ayant une viscosite comprise entre 1 et 50 centistokes, et de preference, entre 15 et 20 centistokes). Une consequence de 20 cet avantage est la faible consommation en gaz 5 : le rapport de la masse du gaz 5 a sur la masse du liquide 4 introduits clans la chambre de melange 2 est inferieure a 0,1 (comprise entre 0,06 et 0,2, ce rapport augmentant avec la viscosite du liquide 4 a pulveriser).Thus, the advantages of such a mixing chamber 2 and of such a spraying device 1 are numerous. The liquid 4 and the mixture 3 do not come into contact with the mixing chamber 2, so that the liquid 4 (and thus the mixture 5) can contain particles whose particle size is greater than a few millimeters. As a result, the liquid 4 does not undergo a significant loss of pressure and can therefore be delivered at a much lower pressure than conventional sprayers: it can range from 0.1 to 2 bar, and preferably between 0.2 and 1 bar. On the other hand, again for the same reason, once the mixture 3 has been made, the early separation of the liquid 4 and the gas 5 is limited, and, as a result, the gas 5 can be delivered at a much lower pressure than clams. conventional sprayers: it may range from 0.1 to 3 bar, and preferably from 0.2 to 1 bar (for a liquid 4 having a viscosity of between 1 and 50 centistokes, and preferably between 15 and 20 centistokes). One consequence of this advantage is the low gas consumption 5: the ratio of the mass of the gas 5a to the mass of the liquid 4 introduced into the mixing chamber 2 is less than 0.1 (between 0.06 and 0 , 2, this ratio increasing with the viscosity of the liquid 4 to be sprayed).
25 La presente invention n'est pas limitee aux modes de realisation decrits. I1 serait ainsi possible que la conduite de sortie soit de forme conique et son angle d'orientation peut titre compris entre 0 et 900 par rapport a la direction longitudinale. De plus, le nombre de 30 conduites de sortie peut titre superieur a deux. I1 serait aussi possible que 1'enceinte ne soit pas en matiere poreuse, mais presentent des petites canalisations, de preference regulierement reparties, ou soit realisee par un 6 2894854 assemblage d'elements dont certains d'entre eux presentent des espaces qui forment des canalisations. L'enceinte pourrait ainsi etre formee par un empilage de plaques (de rondelles) qui comportent chacune des rainures pouvant etre 5 realisees par usinage ou par emboutissage, les orifices qui de preference ont un diametre inferieur a 0,1 mm etant realises par la reunion des rainures de deux plaques adjacentes. De plus, le dispositif de pulverisation peut etre utilise pour la pulverisation de tout types de 10 liquides combustibles ou non. 7The present invention is not limited to the described embodiments. It would thus be possible for the outlet duct to be of conical shape and its orientation angle may be between 0 and 900 with respect to the longitudinal direction. In addition, the number of outlet pipes may be greater than two. It would also be possible for the enclosure not to be porous, but to have small channels, preferably regularly distributed, or to be realized by an assembly of elements some of which have spaces which form channels. . The enclosure could thus be formed by a stack of plates (washers) each having grooves that can be made by machining or stamping, the orifices which preferably have a diameter of less than 0.1 mm being made by the meeting grooves of two adjacent plates. In addition, the spraying device can be used for spraying any kind of combustible or non-combustible liquids. 7
