Definitions
- the field of the present invention is that of heat and / or material exchange columns and more particularly of devices for maintaining heat and / or material exchange means arranged in such columns.
- Heat and / or material exchange columns are used today in a wide variety of processes. For example, these heat and / or material exchange columns make it possible to implement washing processes, cooling processes, reheating processes or even distillation processes. All of these processes are based on the same basic principle, namely the exchange of heat and / or material between two fluids. These two fluids can for example be two liquids, two gases or even a liquid and a gas.
- Such columns thus comprise at least one means of exchanging heat and / or material which is traversed by the two fluids and at which the exchange of heat and / or material between these two fluids takes place.
- these heat and / or material exchange means are based on a support element which can be directly secured in the heat exchange column and / or material concerned, or more particularly on a peripheral wall of this column of heat exchange and / or material, or which can rest against a structural element, itself secured to the peripheral wall of the heat exchange column and / or material.
- a drawback of current support elements lies in particular in the fact that their retention in the heat and / or material exchange column is conditioned by a step of fixing, for example brazing or welding, of this support element, or of the structural element against which it rests, in the heat and / or material exchange column.
- the present invention falls within this context and aims to overcome at least this drawback by proposing a device for maintaining a means of exchanging heat and / or material which is simple and inexpensive in terms of manufacture, configured to support this heat and / or material exchange means, without it having to be secured to the heat and / or material exchange column.
- An object of the present invention thus relates to a heat and / or material exchange column comprising at least one peripheral wall delimiting an internal volume in which are arranged at least one exchange and heat means and at least one heat transfer device. maintaining the heat and / or material exchange means, the device comprising at least two flexible blades in which are formed at least two notches, the blades extending mainly in a main direction of extension between two longitudinal ends.
- the notches are configured to adjust a dimension of elongation of the blades, along said main direction of extension, to a dimension of the heat and / or material exchange column.
- the notches formed in the strips give them an elasticity which allows, on the one hand, the introduction of the strip into the column for exchanging heat and / or material for which it is intended and, d 'on the other hand, which ensures that these blades are maintained in this heat exchange column and / or material once they are positioned there.
- At least the longitudinal ends of the at least one blade bear against the peripheral wall.
- the two longitudinal ends are interconnected by two transverse edges and the notches are respectively provided closer to one of the longitudinal ends of the blade than to a center of this blade.
- the term “center of the blade” is understood to mean a point of this blade equidistant from the two longitudinal ends of this blade and also equidistant from the two transverse edges of this blade.
- the two transverse edges of the blade are mutually parallel, that is to say that, according to this particular example, the blade has a substantially rectangular shape.
- each notch extends from one of the transverse edges of the blade.
- the blade comprises at least four notches distributed in pairs, each pair of notches being provided closer to a longitudinal end of the blade than to the center of this blade.
- the two notches of a pair of notches respectively extend from opposite transverse edges of the blade.
- the two notches of each pair of notches are arranged head to tail. It will be understood that the greater the number of notches made on the blade, the greater the elasticity of this blade.
- At least one longitudinal end of the blade has at least one chamfer.
- at least one longitudinal end of the blade has two chamfers connected to one another by an edge.
- the two longitudinal ends of the blade each have two chamfers connected together by an edge.
- the holding device comprises at least two blades.
- these two blades can cross.
- these blades cross substantially at their center, that is to say at a point equidistant from the two longitudinal ends of the blade concerned.
- these blades can for example be arranged in an X or in a cross.
- the holding device comprises at least four blades which form a lattice.
- these blades can be parallel two by two.
- at least two blades extend predominantly in a first direction and by “at least two blades extend predominantly in a second direction” is meant the fact that the two blades concerned extend in two directions parallel to the first. direction or second direction.
- these slats can thus form a grid, that is to say that the slats define rectangular or even square openings.
- the size of the holding device can be adapted by modulating the number of blades and / or at least one dimension of a blade.
- We can thus increase or reduce the dimensions of this holding device by adding blades in one direction or the other, that is to say by adding blades which extend mainly in the first direction or in the second direction.
- the holding device according to the present invention is thus easily adaptable to all types of heat and / or material exchange columns.
- at least one blade comprises at least one slot configured to receive another blade. In other words, it is understood that these blades are nested on top of each other.
- the at least one slot may have a dimension equivalent, or substantially equivalent, to a transverse dimension of the blade that it receives, that is to say a dimension measured parallel to a line perpendicular to the main direction extension of the affected blade.

Since these blades are also flexible, their insertion into the column generates an elastic deformation of these blades, and once in position in the column, they tend to resume their original shape. In fact, the longitudinal ends of each blade exert a force against the peripheral wall of the heat and / or material exchange column, thus ensuring the position of the holding device in the heat exchanger column and / or matter. In other words, the mechanical strength of the retaining device according to the invention in the heat and / or material exchange column does not require any additional fixing means.

In other words, this ensures the position of the means of heat and / or material exchange along the main extension axis of the heat and / or material exchange column in which it is arranged. For example, the transport of this heat and / or material exchange column is thus facilitated.
- At least one mesh structure may be arranged between the heat and / or material exchange means and at least one holding device according to the invention.

- the heat exchange means 230 can also be made of stainless steel. In any event, this heat exchange means 230 will be made of a material whose melting point is greater than 500 ° C. for the reasons mentioned above.
- This heat exchange means 230 may for example comprise loose packings, such as balls and / or spirals and / or rings and / or structured packings, for example corrugated or flat plates extending predominantly in a direction parallel to the main extension X axis of the column. Whatever it is, the exchange means 230 makes it possible to increase a contact surface, and therefore heat and / or material exchange, between the first fluid and the second fluid which circulate in the column 200.
- FIG. 3 is a perspective view of the holding device 240 according to a first embodiment of the present invention
- Figure 4 is a perspective view of the holding device 240 according to a second embodiment of the present invention. invention.
- first and second exemplary embodiments we will describe the characteristics common to the first and second exemplary embodiments before further describing the characteristics specific to each exemplary embodiment.
- the blades 241 of a holding device 240 according to the invention are identical so that the references on one of them are directly transposable to the others.
- the holding device 240 comprises at least two blades 241 which have at least the characteristics described above, with reference to FIG. 2. As illustrated, these blades 241 intersect, generating thus or at least four openings 249 between the peripheral wall of the column through which the holding device 240 is intended to be arranged and the contact zones which the longitudinal ends 242 of these blades 241 participate in forming, and more particularly, the ridges 248 of these longitudinal ends 242.
- each blade 241 comprises at least four notches 245 distributed in pairs near each longitudinal end 242 of the blade 241 concerned.
- the term “close to” is understood to mean the fact that these notches 245 are made closer to the corresponding longitudinal end 242 of the blade 241 than to the center of the blade 241. this blade 241.
- the two notches 245 of the same pair of notches 245 are formed from two opposite transverse edges 244 of the blade 241 concerned. In other words, the two notches 245 of the same pair of notches 245 are provided head to tail.
- the two notches 245 formed as close as possible to each longitudinal end 242, are made from the same transverse edge 244 of the blade 241.
- the notches 245 of two nested blades 241 l ' one on the other by virtue of the slots 243 are provided as a mirror. In other words, between two blades 241 which cooperate via their slots 243, there is an inversion of the notches 245 vis-à-vis the transverse edges 244 from which they extend.
- the head-to-tail arrangement of the notches 245 ensures that the blade 241 is deformed in the right direction when it is inserted into the column, that is to say that this blade 241 is deformed in the direction a decrease in length. In other words, it is thus ensured that the blade 241 is deformed in the direction of bringing its longitudinal ends 242.
- the manufacture of the blades 241 can thus be standardized, so that the manufacturing costs of a holding device 240 according to the invention are less.
- a transverse edge 244 of at least two blades 241, advantageously a transverse edge 244 of each blade 241, participates in defining the plane P against which the means 230 for exchanging heat and / or material is supported, that is to say that at least two blades 241 have a transverse edge 244 participating in forming the bearing surface of the exchange means 230. It is understood that in the case where the mesh structure 260 is interposed between the exchange means 230 and the holding device 240, it is this mesh structure 260 which rests against this bearing surface, the exchange means 230 resting against this mesh structure 260.
- the holding device 240 comprises two blades 241 which substantially cross at their centers.
- each of these two blades 241 comprises a slot formed from one of its transverse edges 244 as described above and which extends towards the other transverse edge 244, passing through the center of this blade 241.
- the holding device 240 according to this first exemplary embodiment of the present invention takes an X shape, and more precisely a cross shape. We understands that four openings 249 are thus generated between these blades 241 and the internal face 212 of the peripheral wall 210 of the column 200.
- the holding device 240 comprises four blades 241 arranged in a lattice. More particularly, these four blades 241 are, according to this second exemplary embodiment, parallel two by two. In other words, the main directions of extension of these blades are parallel to each other, two by two. Thus, two of these blades 241 extend mainly in a first direction D1, the other two blades 241 extend in a second direction D2, the first direction D1 being perpendicular to the second direction D2. As illustrated in Figure 3, the directions of main extension of two first blades 241 a are parallel to the first direction D1 and the directions of main extension of two second blades 241 b are parallel to the second direction D2.
- this ninth opening 249 is generated between these four blades 241. .
- this ninth opening 249 is square, that is to say that the blades 241 form a grid.
- the holding device 240 could comprise more blades 241 than what has just been described.
- the holding device 240 could comprise more blades 241 than what has just been described.
- the holding device 240 could comprise more blades 241 than what has just been described.
- the holding device 240 could comprise more blades 241 than what has just been described.
- the holding device 240 could comprise more blades 241 than what has just been described.
- the holding device 240 could comprise more blades 241 than what has just been described.
- the holding device 240 could comprise more blades 241 than what has just been described.
- the holding device can be easily adapted to different columns, that is to say columns whose dimensions vary, and more particularly columns of different sections.
- the present invention thus provides a simple, inexpensive means that does not require an assembly operation to maintain the vertical position of a heat and / or material exchange means in a heat exchange column and / or. or material, that is to say to maintain the position of this exchange means along a main axis of extension of this column, regardless of the position of this column.
- the present invention should not, however, be limited to the means and configurations described and illustrated here, and it also extends to any equivalent means and configuration and to any technically operative combination of such means.
- the shape and arrangement of the constituent blades of the holding device according to the invention can be modified without harming the invention insofar as they fulfill the functions described and illustrated in this document.
