Abstract
Description
De nombreuses applications des gaz de pétrole liquéfié en bouteille demandent pour l'alimentation d'un brûleur de chauffage un débit important (rôtissoire à poulet, friteuse, désherbage, marquage thermique, etc.). Dans la pratique, on est vite limité par les possibilités de débit des bouteilles et l'on est conduit à en associer un grand nombre en parallèle, ce qui pose des problèmes de poids, d'encombrement et de sécurité du fait des raccords multiples. Le débit d'une bouteille de gaz de pétrole liquéfié dépend de la température. Plus celle-ci est élevée, plus le débit possible est grand. Le débit dépend également de la durée de l'utilisation. Plus celle-ci est longue, plus le débit est petit. Une demande de gaz trop importante entraîne une baisse de température et, par conséquent, une chute de pression qui peut se traduire par le givrage des parois de la bouteille qui, en raison de son effet isolant, rend le problème encore plus aigu.Many applications of bottled liquefied petroleum gases require a high flow rate for the feeding of a heating burner (chicken roaster, deep fryer, weeding, thermal marking, etc.). In practice, it is quickly limited by the possibilities of flow of bottles and we are led to associate a large number in parallel, which poses problems of weight, bulk and safety due to multiple connections. The flow rate of a bottle of liquefied petroleum gas depends on the temperature. The higher it is, the greater the flow possible. The flow also depends on the duration of use. The longer it is, the smaller the flow. Too much gas demand causes a drop in temperature and, consequently, a pressure drop that can result in frosting of the walls of the bottle which, because of its insulating effect, makes the problem even more acute.
L'invention pallie ces inconvénients par un dispositif de chauffage à brûleur de gaz de pétrole liquéfié, comprenant une bouteille de gaz de pétrole liquéfié ayant une phase gazeuse au-dessus d'une phase liquide et un conduit d'alimentation permettant d'alimenter le brûleur en la phase gazeuse, qui permet d'augmenter le débit et de le maintenir à un niveau sensiblement constant, quelle que soit la température extérieure et la consommation, tout en étant d'une grande sécurité d'emploi.The invention overcomes these disadvantages by a liquefied petroleum gas burner heating device, comprising a bottle of liquefied petroleum gas having a gaseous phase over a liquid phase and a supply line for supplying the liquid. burner in the gas phase, which increases the flow rate and maintains it at a substantially constant level, regardless of the outside temperature and consumption, while being of great safety.
Suivant l'invention, il est prévu des moyens de chauffage de la bouteille et des moyens destinés à interrompre l'action des moyens de chauffage lorsque la pression du gaz de pétrole liquéfié dans la bouteille atteint un seuil donné.According to the invention, there are provided means for heating the bottle and means for interrupting the action of the heating means when the pressure of the liquefied petroleum gas in the bottle reaches a given threshold.
Comme on chauffe la bouteille et on la porte à une température donnée, supérieure à la température ambiante, la bouteille est apte à fournir un débit constant à une pression donnée. Si la pression vient à s'élever au-delà la pression de service, par exemple de 13 bar pour du propane (qui correspond à 42°C) et de 10 bar pour un mélange à 60% en volume de butane et à 40% en volume de propane, ce qui peut mettre en danger la bouteille, les moyens, notamment à pressostat, destinés à interrompre l'action des moyens de chauffage entrent en action et interrompent le chauffage de la bouteille. La pression diminue. De préférence, les moyens destinés à interrompre l'action des moyens de chauffage lorsque la pression du gaz de pétrole liquéfié dans la bouteille atteint un seuil donné sont tels qu'ils interrompent aussi l'action des moyens de chauffage lorsque la pression du gaz de pétrole liquéfié dans la bouteille devient inférieure à une valeur limite inférieure au seuil donné. On évite ainsi de chauffer la bouteille dont le robinet est fermé et qui ne communique pas avec le pressostat.As the bottle is heated and is heated to a given temperature, higher than the ambient temperature, the bottle is able to provide a constant flow rate at a given pressure. If the pressure rises above the operating pressure, for example 13 bar for propane (which corresponds to 42 ° C) and 10 bar for a mixture at 60% by volume of butane and at 40% by volume of propane, which can endanger the bottle, the means, including pressure switch, intended to interrupt the action of the heating means come into action and interrupt the heating of the bottle. The pressure decreases. Preferably, the means for interrupting the action of the heating means when the pressure of the liquefied petroleum gas in the bottle reaches a given threshold are such that they also interrupt the action of the heating means when the pressure of the gas of liquefied petroleum in the bottle becomes lower than a limit value below the given threshold. This avoids heating the bottle whose valve is closed and which does not communicate with the pressure switch.
Les moyens de chauffage peuvent être des moyens électriques ou des moyens de chauffage par de l'air chaud. Certes, l'air chaud a une faible conductibilité et a tendance à s'échapper notamment vers le haut. Mais, en dépit de ces inconvénients, il présente les avantages décisifs, par rapport par exemple à de l'eau, de ne pas geler, d'être moins dense et donc moins lourd et de ne pas provoquer de giclées lors du transport, ni de corrosion.The heating means may be electrical means or heating means by hot air. Certainly, hot air has low conductivity and tends to escape especially upward. But, despite these disadvantages, it has the decisive advantages, for example with respect to water, not to freeze, to be less dense and therefore lighter and not cause spurts during transport, nor corrosion.
Suivant un mode de réalisation, les moyens de chauffage comprennent un brûleur alimenté par une dérivation en le gaz de pétrole liquéfié contenu dans la bouteille. Le dispositif est ainsi autonome du point de vue thermique.According to one embodiment, the heating means comprise a burner fed by a bypass of the liquefied petroleum gas contained in the bottle. The device is thus autonomous from the thermal point of view.
Suivant un mode de réalisation particulier, les moyens de chauffage comprennent une chaudière dont le foyer est alimenté en gaz de pétrole liquéfié provenant de la bouteille et qui comporte un circuit ayant un conduit de sortie d'eau chaude allant à un échangeur de chaleur et un conduit de retour allant de l'échangeur à la chaudière et une pompe de circulation. Un ventilateur insuffle de l'air dans l'échangeur de chaleur et le dirige sur la bouteille, de préférence à la partie inférieure de celle-ci. Suivant un mode de réalisation tout particulièrement préféré, l'échangeur de chaleur, le ventilateur et la partie inférieure de la bouteille sont enfermés dans une enceinte, de préférence calorifugée, et il est prévu dans l'enceinte une chicane disposée de manière à ce que l'air, après avoir cédé de la chaleur à la bouteille, soit repris par le ventilateur. Grâce au fait que l'air est enfermé dans une enceinte, il ne s'échappe pas vers le haut à l'extérieur et comme il est repris constamment, la quantité d'énergie thermique à fournir est réduite autant que possible. De préférence, la partie supérieure de la bouteille est hors de l'enceinte et il est prévu des joints d'étanchéité entre la bouteille et l'enceinte à la transition entre les parties inférieure et supérieure de la bouteilleAccording to a particular embodiment, the heating means comprise a boiler whose furnace is supplied with liquefied petroleum gas from the bottle and which comprises a circuit having a hot water outlet duct going to a heat exchanger and a furnace. return line from the exchanger to the boiler and a circulation pump. A fan blows air into the heat exchanger and directs it onto the bottle, preferably at the bottom of the bottle. According to a very particularly preferred embodiment, the heat exchanger, the fan and the lower part of the bottle are enclosed in an enclosure, preferably insulated, and there is provided in the enclosure a baffle disposed of so that the air, after giving heat to the bottle, is taken up by the fan. Due to the fact that the air is enclosed in an enclosure, it does not escape upwards to the outside and as it is constantly taken over, the amount of thermal energy to be supplied is reduced as much as possible. Preferably, the upper part of the bottle is out of the enclosure and there are provided seals between the bottle and the enclosure at the transition between the lower and upper parts of the bottle
Suivant un perfectionnement, une sonde de température est disposée dans le flux d'air, de préférence le plus près possible de la bouteille et il est prévu un circuit électrique de mise à l'arrêt des moyens de chauffage, de préférence de la pompe, lorsque la sonde détecte une température supérieure à un seuil de température donné. On dispose ainsi d'une sécurité supplémentaire en plus de celle due à la surveillance de la pression à l'intérieur de la bouteille.According to an improvement, a temperature probe is arranged in the air flow, preferably as close as possible to the bottle and there is provided an electrical circuit for shutting down the heating means, preferably the pump, when the probe detects a temperature above a given temperature threshold. This provides additional safety in addition to that due to the monitoring of the pressure inside the bottle.
Suivant une variante, on fournit de l'air chaud à l'aide d'un ventilateur qui envoie de l'air sur une résistance électrique chauffante, le ventilateur, la résistance et la partie inférieure de la bouteille étant enfermés dans une enceinte.According to one variant, hot air is supplied by means of a fan that sends air to an electric heating element, the fan, the resistor and the lower part of the bottle being enclosed in an enclosure.
Dans un mode de réalisation préféré, l'enceinte se trouve dans une chambre inférieure délimitée par un socle et par un fond horizontal, tandis qu'une cloison, de préférence verticale, subdivise l'espace supérieur en un compartiment comprenant les moyens de chauffage et de régulation et en un autre compartiment comprenant les bouteilles. En cas de fuite, on prévient ainsi tout danger d'incendie.In a preferred embodiment, the enclosure is in a lower chamber delimited by a base and a horizontal bottom, while a partition, preferably vertical, divides the upper space into a compartment comprising the heating means and regulator and another compartment comprising the bottles. In the event of a leak, this prevents any danger of fire.
L'invention vise également un procédé d'alimentation en gaz de pétrole liquéfié en phase gazeuse à partir d'une bouteille de gaz de pétrole liquéfié qui consiste à chauffer la bouteille et à interrompre le chauffage lorsque la pression du gaz de pétrole liquéfié dans la bouteille atteint un seuil donné.The invention also relates to a method for supplying liquefied petroleum gas in the gas phase from a bottle of liquefied petroleum gas which consists of heating the bottle and interrupting the heating when the pressure of the liquefied petroleum gas in the bottle reaches a given threshold.
Le brevet des Etats-Unis d'Amérique n° 5 761 911 (Jurcik) décrit un dispositif d'alimentation en gaz liquéfié. Ces gaz liquéfiés ne sont pas des gaz de pétrole. Ce sont des gaz utilisés dans les procédés de fabrication de semi conducteurs tels qu'ils sont énumérés au tableau I. Le document
Ce document antérieur vise à empêcher que des gouttelettes soient entraînées avec les gaz. Pour éviter cela, il ne faut pas qu'il se produise de bouillonnement, ce qui signifie qu'il ne faut pas trop chauffer. II faut chauffer pour compenser simplement l'effet endothermique de l'évaporation. A cet effet, et comme mentionné explicitement à la page 4, lignes 14 à 18, le document antérieur prévoit des moyens pour augmenter la vitesse de transfert de chaleur entre l'atmosphère ambiante et la bouteille sans élever la température de la bouteille de gaz au-dessus de la température ambiante.This prior document aims to prevent droplets being entrained with the gases. To avoid this, it must not happen bubbling, which means you should not overheat. It is necessary to heat to simply compensate for the endothermic effect of evaporation. For this purpose, and as mentioned explicitly on page 4,
La présente invention préconise à l'opposé de maintenir la température de la bouteille de gaz de pétrole liquéfié à une valeur donnée quelle que soit la température ambiante. La valeur donnée est le plus souvent, notamment en hiver, supérieure à la température ambiante. Cela permet d'augmenter le débit et de le maintenir à un niveau sensiblement constant.The present invention recommends the opposite to maintain the temperature of the bottle of liquefied petroleum gas at a given value regardless of the ambient temperature. The value given is most often, especially in winter, higher than the ambient temperature. This makes it possible to increase the flow rate and maintain it at a substantially constant level.
Le brevet des Etats-Unis d'Amérique n° 5 557 940 (Hendricks) décrit une unité portative de chauffage pour ajouter du réfrigérant à un système de refroidissement qui est déchargé. Il explique que le chargement sur site de systèmes de refroidissement, tels que de conditionneurs d'air, de congélateurs et de réfrigérateurs, pose problème par temps froid parce que le réfrigérant se refroidit au point où il est difficile d'obtenir une pression de vapeur de chargement. Lorsqu'un réfrigérant est envoyé à un réfrigérateur à partir d'une bouteille le contenant, il y est envoyé sous forme de liquide. Pour former des frigories, le liquide est évaporé.U.S. Patent No. 5,557,940 (Hendricks) discloses a portable heating unit for adding refrigerant to a cooling system that is discharged. He explains that the on-site loading of cooling systems, such as air conditioners, freezers and refrigerators, is problematic in cold weather because the refrigerant cools to the point where it is difficult to obtain vapor pressure. loading. When a refrigerant is sent to a refrigerator from a bottle containing it, it is sent as a liquid. To form frigories, the liquid is evaporated.
Le document Hendricks préconise de chauffer la bouteille de manière à ce que le gaz, qui s'y trouve dans la partie supérieure, soit sous une pression suffisante pour pousser la phase liquide qui est à la partie inférieure. Dans le dispositif de Hendricks, on n'alimente pas en gaz de pétrole liquéfié et on n'alimente pas en une phase gazeuse.The Hendricks document recommends heating the bottle so that the gas, which is in the upper part, is under a pressure sufficient to push the liquid phase which is at the bottom. In the Hendricks device, no liquefied petroleum gas is fed and no gas phase is supplied.
