Description

L'invention concerne un dispositif de vaporisation d'un liquide au moyen d'un gaz, qui est enrichi par la vapeur ainsi obtenue. La vaporisation des liquides peut notamment se faire par échauffement, par baisse de la pression, par pulvérisation (atomisation) ou par barbotage. Ce dernier moyen, simple et fiable est sous-utilisé en raison de la difficulté de maintenir une perte de eharge constante à débit de gaz constant, en raison de la variation de niveau du liquide vaporisé. Maintenir ce niveau constant complexifie ce procédé, lui retirant son avantage. D'autre part son emploi dans l'industrie nécessite un certain nombre de sécurités, qui sont elles-mêmes une source de complexité. La présente invention apporte une réponse à ce problème. D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après à titre indicatif et nullement limitatif, en référence aux dessins annexés (fig. 1 vue générale en coupe et fig. 2 coupe horizontale du flotteur) Le dispositif se présente comme un récipient (0) comportant des caractéristiques détaillées ci-après Le gaz est mu par une différence de pression entre l'entrée et la sortie du dispositif, créée par tout moyen, et gardée constante de par la conception du ladite invention. Le gaz arrive par le tube d'entrée (1) et circule dans l'espace (2) compris entre le flotteur (3) et ledit tube. La forme interne du flotteur (3) a pour fonction de guider celui-ci sur le tube et de permettre le passage du gaz comme le montre la coupe horizontale (fig.2). Le flotteur (3) comporte un insert (4a) destiné à obturer le passage du gaz si le niveau de liquide est trop bas, pour prévenir un fonctionnement sans évaporation dans le cas où celui-ci pourrait perturber l'ensemble du procédé auquel il est destiné. Le flotteur (3) comporte également un insert (5) destiné à actionner un capteur sans contact (6), destiné à avertir du niveau bas, ou haut. En option, les ouvertures (7) et (8) permettent de re4remplir le volume de barbotage sur indication de ce niveau bas, sous le contrôle de tout moyen approprié relevant de l'automatisation classique de la circulation des fluides. La hauteur de liquide (9) que le gaz doit vaincre reste constante, uniquement déterminée par la densité du flotteur, ledit flotteur ayant toujours la même position par rapport à la surface du liquide. La formation de bulles de ce gaz dans le liquide développe une surface d'échange à travers laquelle le liquide peut s'évaporer. Le tube d'entrée (1) fait office de niveau maximum par débordement, et dans ce cas le surplus de liquide sera stocké en amont du tube d'entrée, par gravité, dans une cavité appropriée (10). Les bulles formées s'échappent à la surface tout autour du flotteur et sortent par la sortie (11). Cette sortie est constituée d'un bouchon vissé (12) permettant l'inspection du dispositif sans déconnecter le tube de sortie (13) de l'aval du circuit, grâce à une rondelle tournante (14). En outre, en cas d'afflux accidentel de liquide en grande quantité, cette sortie voit son débit limité ou annulé par la remontée du flotteur qui peut atteindre ladite sortie et l'obturer au moyen d'un insert (4b), par exemple de type pointeau. Le dispositif comporte une cavité quasi cylindrique (15) permettant l'adjonction d'un moyen de chauffage optionnel, comme par exemple un tuyau parcouru par un fluide annexe caloporteur. Ce moyen de chauffage est destiné à maintenir une température suffisante pour un débit évaporatoire convenable à l'ensemble du procédé, dans le cas où la température extérieure descendrait en dessous d'un seuil critique préjudiciable au bon fonctionnement du procédé en aval, ou au bon fonctionnement du dispositif lui-même, par exemple pour garantir que le liquide n'atteigne pas son point de solidification. The invention relates to a device for vaporizing a liquid by means of a gas, which is enriched by the vapor thus obtained. The vaporization of the liquids can in particular be done by heating, by lowering the pressure, by spraying (atomization) or by bubbling. This latter simple and reliable means is underutilized due to the difficulty of maintaining a constant constant gas flow rate loss due to the level variation of the vaporized liquid. Keeping this level constant complicates this process, removing its advantage. On the other hand its employment in the industry requires a number of securities, which are themselves a source of complexity. The present invention provides an answer to this problem. Other features and advantages of the invention will become apparent from the description which is given below by way of indication and in no way limiting, with reference to the accompanying drawings (Fig 1 general view in section and Fig 2 horizontal section of the float The device is in the form of a container (0) with characteristics detailed below. The gas is moved by a pressure difference between the inlet and the outlet of the device, created by any means, and kept constant by the design of the device. said invention. The gas arrives through the inlet tube (1) and circulates in the space (2) between the float (3) and said tube. The internal shape of the float (3) has the function of guiding it on the tube and allow the passage of gas as shown in the horizontal section (fig.2). The float (3) comprises an insert (4a) intended to close off the passage of the gas if the liquid level is too low, to prevent operation without evaporation in the case where this could disturb the whole process to which it is intended. The float (3) also comprises an insert (5) for actuating a non-contact sensor (6), intended to warn of the low level, or high. As an option, the openings (7) and (8) make it possible to replenish the sparging volume on the indication of this low level, under the control of any appropriate means pertaining to the conventional automation of the circulation of fluids. The height of liquid (9) that the gas must overcome remains constant, determined solely by the density of the float, said float always having the same position relative to the surface of the liquid. The formation of bubbles of this gas in the liquid develops an exchange surface through which the liquid can evaporate. The inlet tube (1) acts as a maximum level by overflow, and in this case the excess liquid will be stored upstream of the inlet tube, by gravity, in a suitable cavity (10). The formed bubbles escape to the surface all around the float and exit through the outlet (11). This outlet consists of a screw cap (12) for inspection of the device without disconnecting the outlet tube (13) from the downstream of the circuit, by means of a rotating washer (14). In addition, in case of accidental influx of liquid in large quantities, this outlet sees its flow limited or canceled by the rise of the float which can reach said outlet and seal with an insert (4b), for example of needle type. The device comprises a quasi-cylindrical cavity (15) allowing the addition of an optional heating means, such as for example a pipe traversed by a heat transfer fluid. This heating means is intended to maintain a sufficient temperature for an evaporative flow rate suitable for the entire process, in the case where the outside temperature would fall below a critical threshold detrimental to the proper functioning of the downstream process, or to the good operation of the device itself, for example to ensure that the liquid does not reach its solidification point.

Les matériaux employés devront être compatibles avec les fluides en jeu. Par exemple si de l'eau est évaporée dans de l'air l'acier inoxydable est approprié, notamment pour le carter (0), le tube (1) et pour les composants (12,13,14) de la sortie. Le flotteur (3) est par exemple en mousse de PVC, avec ses inserts (4a) et (4b) en caoutchouc. The materials used must be compatible with the fluids involved. For example, if water is evaporated in air, the stainless steel is suitable, especially for the casing (0), the tube (1) and for the components. (12,13,14) from the exit. The float (3) is for example PVC foam, with its inserts (4a) and (4b) rubber.

L'insert (5) est par exemple métallique pour actionner le capteur (6) par exemple inductif. Les applications de ce dispositif sont multiples, comme par exemple la carburation ou l'humidification de l'air, ou encore la désodorisation.10 The insert (5) is for example metallic to actuate the sensor (6) for example inductive. The applications of this device are multiple, such as, for example, the carburization or the humidification of the air, or the deodorization.
