Abstract
Description
L'invention se rapporte aux moyens de chauffage des citernes ainsi qu'aux citernes pourvues de ces moyens.The invention relates to means for heating tanks and to tanks provided with these means.
Qu'il s'agisse de citernes fixes ou de citernes portées par des véhicules routiers ou ferroviaires, on sait que pour certains produits leur vidange voire même leur remplissage nécessite un réchauffage de la dite citerne.Whether they are fixed tanks or tanks carried by road or rail vehicles, it is known that for certain products their emptying or even their filling requires heating of said tank.
Ces citernes présentent classiquement un corps cylindrique d'axe sensiblement horizontal, fermé à ses extrémités par des fonds et reposant sur un support par l'intermédiaire d'au moins deux berceaux.These tanks conventionally have a cylindrical body with a substantially horizontal axis, closed at its ends by bottoms and resting on a support by means of at least two cradles.
Autour de la paroi de la citerne, est réalisé un chemisage calorifugé généralement en demi-coquille réservant entre sa paroi interne et la paroi de la citerne une chambre périphérique partiellement traversée par les berceaux.Around the wall of the tank, a heat-insulated jacket is generally produced in a half-shell reserving between its internal wall and the wall of the tank a peripheral chamber partially crossed by the cradles.
Pour le réchauffage des grosses citernes et des produits qu'elles contiennent, il est connu de faire appel à une énergie extérieure telle de la vapeur saturée ou surchauffée envoyée dans un réseau soit de tubes plongeant dans le contenu de la citerne, soit de conduits formés d'une tôle plus ou moins galbée appliquée contre la paroi de la citerne qui est alors utilisée comme surface de condensation et de récupération de la chaleur dégagée par le changement d'état.For the heating of large tanks and the products they contain, it is known to use external energy such as saturated or superheated steam sent in a network either of tubes immersed in the contents of the tank, or of ducts formed a more or less curved sheet applied against the wall of the tank which is then used as a surface for condensation and recovery of the heat released by the change of state.
Selon le produit concerné, la pénétration de tubes de réchauffage dans le dit produit n'est pas toujours autorisée.Depending on the product concerned, the penetration of heating tubes into said product is not always authorized.
Quant à la réalisation de conduits plaqués contre la paroi de la citerne, elle nécessite de faire en sorte que la citerne tienne à la pression extérieure qui, en fonctionnement, lui sera appliquée.As for the realization of conduits pressed against the wall of the tank, it requires ensuring that the tank withstands the external pressure which, in operation, will be applied to it.
Qu'il s'agisse de tubes plongés dans le produit ou de conduits plaqués contre la paroi de la citerne, l'échange reste limité compte tenu de la faiblesse de la surface d'échange ainsi obtenue.Whether they are tubes immersed in the product or conduits pressed against the wall of the tank, the exchange remains limited given the weakness of the exchange surface thus obtained.
Afin de remédier à ces inconvénients, on connaît un chauffage électrique sous la forme de caissons de résistances blindées montés de manière démontable sous la citerne, et ce tout au long de celle-ci.In order to remedy these drawbacks, electrical heating is known in the form of armored resistance boxes mounted in a removable manner under the tank, and this throughout the latter.
Ces résistances blindées chauffent l'air de la chambre périphérique.These shielded resistors heat the air in the peripheral chamber.
Cet air, qui n'est mis en mouvement que par convection naturelle, reste pratiquement statique, aussi les caissons de chauffe n'ont-ils qu'une emissivité très faible de l'ordre de un watt par centimère carré d'où la necessité de prévoir de trés grandes surfaces de chauffe ce qui, pour un ensemble "citerne plus chemisage" de volume extérieur donné, réduit la charge utile de la citerne.This air, which is only moved by natural convection, remains practically static, so the heating boxes have only a very low emissivity of the order of one watt per square centimeter, hence the need to provide very large heating surfaces which, for a "tank plus liner" assembly of given external volume, reduces the payload of the tank.
Par ailleurs, les caissons localisés en partie basse ne permettent pas un chauffage homogène de l'air présent dans la chambre périphérique.Furthermore, the boxes located in the lower part do not allow homogeneous heating of the air present in the peripheral chamber.
De plus, dans le cas de produits dangereux dégageant notamment des gaz inflammables, les résistances blindées disposées sous toute la citerne multiplient les risques d'explosion à la suite d'arcs de court-circuits.In addition, in the case of dangerous products releasing in particular flammable gases, the armored resistors placed under the entire tank multiply the risk of explosion following short-circuit arcs.
On connait également (DE-U-7.120.959 et GB-A-2.049.628) un procédé selon lequel on "partitionne" la chambre de manière à définir, tout autour de la citerne, au moins un cheminement privilégié de l'air en sortie duquel cheminement, on prélève cet air et on le fait passer sur une batterie de chauffage avant de le ramener à l'entrée du cheminement et enfin, on établit dans le cheminement et sur la batterie une circulation forcée de cet air.We also know (DE-U-7,120.959 and GB-A-2,049,628) a process according to which the chamber is "partitioned" so as to define, all around the tank, at least one preferred path of air at the end of which path, this air is taken and it is passed over a heating battery before bringing it back to the entrance of the path and finally, a forced circulation of this air is established in the path and on the battery.
Un résultat que l'invention vise à obtenir est une citerne à réchauffage de ce type qui soit encore plus efficace.One result which the invention aims to obtain is a heating tank of this type which is even more efficient.
A cet effet, l'invention a pour objet de tels moyens de réchauffage de citerne notamment caractérisés en ce que :
- ils comprennent deux tôles découpées en forme de fer à cheval et disposées de manière opposée autour de la citerne dans deux plans diamétraux déphasés de quatre vingt dix degrés l'un de l'autre,
- ces deux tôles en au moins un tronçon sont soudées sur la citerne pour "partitionner" la chambre entre la citerne et le chemisage calorifugé en quatre quadrants et,
- à une extrémité de la citerne, l'une des tôles de partitionnement est prolongée de manière à interdir, avec l'autre tôle toute communication des quadrants qu'elle sépare et des quadrants situés du côté opposé de l'autre tôle pour y former les extrémités du cheminement privilégié où sont raccordées la sortie et l'entrée du dit cheminement.To this end, the subject of the invention is such means for reheating tanks, in particular characterized in that:
- they comprise two sheets cut out in the shape of a horseshoe and arranged in an opposite manner around the tank in two diametrical planes out of phase ninety degrees from each other,
these two sheets in at least one section are welded to the tank in order to "partition" the chamber between the tank and the insulated liner into four quadrants and,
- at one end of the tank, one of the partition sheets is extended so as to prevent, with the other sheet, any communication of the quadrants it separates and of the quadrants located on the opposite side of the other sheet to form there the ends of the preferred path where the exit and the input of said path are connected.
L'invention a également pour objet les citernes pourvues de ces moyens.A subject of the invention is also the tanks provided with these means.
Elle sera bien comprise à l'aide de la description ci-aprés faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :
- - figure 1 : une vue en perspective d'une citerne selon l'invention,
- - figure 2 : un schéma montrant le parcours de l'air dans cette citerne,
- - figures 3 à 6 : des coupes selon III-III à VI-VI de la figure 1.
- - Figure 1: a perspective view of a tank according to the invention,
- - Figure 2: a diagram showing the air flow in this tank,
- - Figures 3 to 6: sections according to III-III to VI-VI of Figure 1.
En se reportant au dessin, on voit que la citerne 1 comprend un corps cylindrique 2 d'axe horizontal, lequel corps 2 est fermé à ses extrémités par des fonds 3.Referring to the drawing, it can be seen that the tank 1 comprises a
A cette citerne sont bien entendu raccordées des dispositifs de remplissage et/ou de vidange et au moins un orifice de visite (non représentés).To this tank are of course connected filling and / or emptying devices and at least one inspection opening (not shown).
Cette citerne repose sur un support 4 de tout type connu tel le chassis d'un wagon ou d'un véhicule de transport routier, par l'intermédiaire de berceaux 6.This tank rests on a support 4 of any known type, such as the chassis of a wagon or of a road transport vehicle, by means of
Autour de la citerne est disposé un chemisage calorifugé 8 réservant entre sa paroi interne et la citerne une chambre périphérique 10 partiellement traversée par les berceaux 6.Around the tank is disposed a heat-insulated
Pour chauffer l'air compris dans cette chambre périphérique 10, la chambre 10 est "partitionnée" de manière à définir, tout autour de la citerne 1, au moins un cheminement privilégié de l'air 13 en sortie 16 duquel cheminement 13, on prélève cet air et on le fait passer sur une batterie de chauffage avant de le ramener à l'entrée 20 du cheminement 13 et enfin, on établit dans le cheminement et sur la batterie une circulation forcée de cet air.To heat the air included in this
La conception des citernes est simple et notamment il est inutile de prévoir la tenue de la citerne à la pression extérieure et surtout l'efficacité est meilleure puisque :
- d'une part, toute la surface de la paroi de la citerne est utilisée comme surface d'échange et,
- d'autre part, grâce au cheminement forcé de l'air sur la batterie de chauffage, on obtient une émissivité meilleure et de l'ordre de trois à quatre watts par centimètre carré soit trois à quatre fois plus importante qu'avec un chauffage de l'air circulant par simple convection naturelle.The design of the tanks is simple and in particular it is useless to provide for the holding of the tank at external pressure and above all the efficiency is better since:
- on the one hand, the entire surface of the wall of the tank is used as an exchange surface and,
- on the other hand, thanks to the forced routing of air on the heating coil, we obtain a better emissivity and of the order of three to four watts per square centimeter, ie three to four times greater than with heating air circulating by simple natural convection.
Ces gains en efficacité permettent de réduire l'importance des batteries de chauffage et donc la place qu'elles occupent.These efficiency gains reduce the importance of heating batteries and therefore the space they occupy.
Les moyens en vue de la mise en oeuvre de cette invention comprennent principalement des moyens 21, 22 pour "partitionner" la chambre 10 de manière à définir tout autour de la citerne 1 au moins un cheminement 13 de l'air avec une sortie 16 et une entrée 20 et, intercalée entre la sortie et l'entrée du cheminement, au moins une batterie de chauffage de l'air prélevé en sortie du cheminement ainsi qu'un moyen établissant dans le cheminement et sur la batterie de chauffage une circulation forcée de l'air de la chambre.The means for implementing this invention mainly comprise means 21, 22 for "partitioning" the
La batterie de chauffe et son moto-ventilateur du groupe chauffage ventilation sont situés à l'extérieur de l'ensemble constitué par la citerne et son chemisage calorifugé.The heating coil and its fan motor of the heating and ventilation group are located outside the assembly consisting of the tank and its insulated liner.
L'air chaud est pulsé tout autour de la citerne à travers le cheminement privilégié 13 par l'intermédiaire du groupe de chauffage ventilation fonctionnant en tout air recyclé.The hot air is pulsed all around the tank through the
Le moto-ventilateur peut être du type centrifuge, délivrant une pression plus importante que celle d'un moto-ventilateur tangentiel ce qui permet de compenser la perte de charge du réseau.The motor-fan can be of the centrifugal type, delivering a higher pressure than that of a tangential motor-fan which makes it possible to compensate for the pressure drop of the network.
Les moyens de "partitionnement" comprennent deux tôles 21, 22 découpées en forme de fer à cheval et disposées de manière opposée autour de la citerne dans deux plans diamétraux déphasés de quatre vingt dix degrés l'un de l'autre.The "partitioning" means comprise two
Ces deux tôles, en au moins un tronçon, sont soudées sur la citerne pour "partitionner" la chambre entre la citerne et le chemisage calorifugé en quatre quadrants 32 à 35.These two sheets, in at least one section, are welded to the tank to "partition" the chamber between the tank and the insulated liner into four
A une extrémité de la citerne, l'une des tôles de partitionnement est prolongée de manière à interdir, avec l'autre tôle toute communication des quadrants 32 et 35 qu'elle sépare et des quadrants 33, 34 situés du côté opposé de l'autre tôle pour y former les extrémités du cheminement privilégié 13 où sont raccordées la sortie 16 et l'entrée 20 du dit cheminement.At one end of the tank, one of the partition plates is extended so as to prevent, with the other plate, any communication of the
L'air réchauffé sur la batterie de chauffe du groupe de chauffage ventilation extérieur rentre ainsi dans le premier quadrant 32 tel le quadrant inférieur droit sur la figure 4, et commence à échanger ses calories avec la citerne.The air heated on the heating coil of the outdoor ventilation heating group thus enters the
La conception du berceau 6 de la citerne réserve un passage 36 longitudinal de l'air.The design of the
Parvenu à l'autre extrémité de la citerne, l'air passe dans un second quadrant 33 tel le quadrant supérieur droit puis dans le troisième quadrant 34 tel le quadrant supérieur gauche et enfin dans le quatrième quadrant tel le quadrant inférieur gauche avant de revenir dans le groupe pour y être recyclé.When it reaches the other end of the tank, the air passes into a
Ce cheminement est schématiquement représenté figure 2.This path is schematically represented in Figure 2.
Par rapport aux citernes équipées de caissons chauffants, l'invention présente de nombreux avantages :
- la circulation forcée de l'air autour de la citerne, permet son homogénisation et surtout assure une émission spécifique de puissance par unité de surface des éléments blindés du groupe de chauffage ventilation plus importante que dans le cas d'une convection naturelle.Compared to tanks fitted with heating boxes, the invention has many advantages:
- the forced circulation of air around the tank, allows its homogenization and above all ensures a specific emission of power per unit area of the shielded elements of the ventilation heating group greater than in the case of natural convection.
A puissance égale, la dimension des éléments électriques chauffants s'en trouve nettement réduite.At equal power, the size of the electric heating elements is significantly reduced.
Le coût du dispositif de réchauffage ramené à l'unité citerne est abaissé.The cost of the heating device brought back to the tank unit is lowered.
Aucun parc de pièce de rechange n'est à prévoir.No spare part fleet is to be expected.
Le réchauffage des produits dangereux notamment des gaz inflammables est assuré dans de meilleures conditions et les arcs de court-circuits ne pouvant se produire avec les résistances blindées puisqu'elles sont situées à l'extérieur de l'ensemble citerne chemisage calorifugé.The reheating of dangerous products, in particular flammable gases, is ensured under better conditions and short-circuit arcs cannot occur with armored resistors since they are located outside the insulated tank assembly.
Il est bien évident que l'invention n'est pas limitée à l'exemple de réalisation ci-dessus décrit et représenté à partir duquel l'homme de l'art pourra définir toute variante de réalisation.It is obvious that the invention is not limited to the embodiment described above and shown from which the person skilled in the art can define any variant embodiment.
