Definitions
- the invention relates to the field of exchange and / or reaction between fluids, whether it is the exchange of calories or frigories, for example by heating or cooling, or the exchange of constituents, for example by filtration or separation or absorption or desorption, or by injection of product (s), or by a chemical reaction.
- a device for exchanging between at least two fluids in which, on the one hand, at least one “thick” first chamber is provided, defined by the side walls of a first spacer hollowed out so as to allow the circulation of a first fluid, and on the other hand, at least one second “thin” or thick chamber for the circulation of a second fluid, the first and second chambers being separated by a first exchange wall allowing exchange and / or a reaction, thermal and / or by mass transfer, between the fluids circulating in the first and second adjacent chambers.
- the volume and configuration of the chamber delimited by the spacer are variable. Consequently, the spacer can be completely or partially hollowed out, or define at least two independent sub-chambers. In the latter case, the sub-chambers can be defined by machining or molding.
- the treatment can be either thermal, or "physical" (filtration or separation of constituents), or simultaneously thermal and physical.
- the treatment can also be chemical if a reactive material or a mixture of materials is placed in the first chamber, or if a reactive agent, such as a catalyst, is introduced into it.
- the elements comprising these materials can be fixed on a side wall, or be suspended between two added plates (or stacked), or be added in the volume of the spacer chamber.
- Injection nozzles can be envisaged to allow the injection of one or more reactive products into a chosen area of the chamber.
- the invention can be used for endothermic or exothermic reactions.
- the first spacer may include a first closed side wall, forming the first exchange wall and having an external face arranged to cooperate with a plate, or a first or second closed wall of a spacer of another block, so to define the second bedroom.
- the first spacer and the attached plate (or the first spacer only) define a modular processing block, and several blocks can be mounted in series and / or in parallel, as soon as their first spacer has a second side wall. , parallel (or inclined with respect to) the first closed side wall, and open so as to be closed by the plate of another block (or else closed to define a second chamber with the first wall of the next block).
- the insert plate can be recessed, slightly, in the spacer or placed against it (possibly being attached to it).
- another first spacer is provided, the external face of the first exchange wall of which is intended to be sealed by the plate of the modular block to define another second chamber, the first two spacers and the plate thus defining a modular on-block processing;
- the first spacer may have a first open side wall, and at least a first and a second plate are provided which jointly define the second chamber (either by welding or brazing, or by stacking with the interposition of a seal), the first plate being further intended to close the first side wall open in forming the first exchange wall.
- first spacer and the first and second plates define a modular processing block, and several modular blocks can be mounted in series and / or in parallel as soon as their first spacer has a second open side wall, placed opposite a first open side wall, intended to be closed off by the second plate of another block;
- a second thick spacer can be provided comprising side walls defining a second chamber hollowed out so as to allow the circulation of the second fluid, the first and second spacers respectively presenting first open side walls intended to be placed one opposite the other with the interposition of a separation membrane or a plate forming the first exchange wall.
- first and second spacers and the membrane define a modular processing block, and several modular blocks can be mounted in series or in parallel as soon as their first spacer has a second side wall is open and intended to be placed in sight of a second open side wall of another block with the interposition of another membrane or of a sealed plate, is closed and intended to be placed opposite a second side wall closed of another block;
- the latter can be formed by machining (or recess) or by attachment to an attached plate, of the same nature as the spacer or of a different nature.
- the connection can be final (welding, brazing or bonding) or not final (stacking with the interposition of a seal).
- At least some of the plates forming an exchange wall are equipped with fluid disrupters, so as to promote heat exchanges between first and second fluids.
- the disturbers can be formed on the surface of the plates, for example by stamping, or else secured to the surface of the plates. Alternatively, the disturbers can be housed in the bedrooms.
- at least one of the spacers can accommodate means for injecting fluid, such as an injector making it possible to introduce a third fluid inside the chamber of this spacer. It is also possible to provide several injectors intended for the introduction of fluid (s) or product (s) at selected, different locations, of a spacer.
- At least one of the spacers can accommodate a static, added mixing element, such as for example a vortex, or a metallic foam, or a mouse or a catalytic coating, or even a generator.
- turbulence or an agitator such as, for example, fins offset strip type.
- a spacer may also house several elements of the type of those mentioned above, including elements ensuring different functions. This or these elements may be housed in one, or produced in the form of a cartridge type insert.
- the circulation of the fluid inside a chamber can be either substantially parallel to the closure plates (or side faces), and in a single pass, or non-linear because it follows a flow path, for example in steps, intended to increase its time of presence inside the room, for example.
- a path can be defined by attached cells housed in the room.
- at least one of the spacers can be formed by assembling (or juxtaposition) of at least two sub-spacers, possibly of different dimensions.
- the volume of the chamber thus delimited is chosen as a function, in particular, of the flow parameters: charge, viscosity, residence time and the like.
- the invention relates to numerous applications, and in particular in the field of thermal and / or chemical treatment of a first liquid or fluid, in particular food or chemical, or in the field of separation or mixing of components of a first complex fluid , for example by filtration.
- a first liquid or fluid in particular food or chemical
- a first complex fluid for example by filtration.

- - Figure 19 is a schematic perspective view of a variant of the spacer of Figure 18, equipped with an injector
- - Figure 20 is a schematic perspective view of a spacer comprising a guide defining a fluid circulation path.
- the device comprises a first thick spacer 1, the side walls of which delimit a first chamber 2, hollowed out so as to allow the circulation of a first fluid.
- the dimensions of the spacer 1, and in particular its thickness, are chosen according to the characteristics of the first fluid and of the exchanges and / or treatment to be carried out.
- spacer is meant here either a single block, or a juxtaposition of several blocks or sub-blocks.
- the word spacer must be understood as an element or set of elements defining a fluid circulation chamber.
- This type of device can indeed be used to treat fluids by controlling the residence time and / or the reaction time. However, it can also be used to treat fluids having a high viscosity or containing fibers or particles.
- the first fluid enters the first chamber 2 through an inlet 3 formed in a part (here the "upper" part) of the first spacer 1.
- This inlet 3 is supplied by a first supply circuit 4 which is, for example, connected to a reservoir of first fluid to be treated.
- the first spacer 1 also comprises, in another side wall (here in its "lower” part) an outlet 5 connected to the supply circuit 4 to evacuate from the first chamber 2 the first fluid treated therein.
- the treatment of the first fluid consists of heating, or cooling, using a second fluid which circulates in a second hollowed-out chamber 6, defined by the side walls of a second spacer 7.
- the thickness of this second spacer 7 is chosen according to the characteristics of the fluid which it must receive.
- spacers 1 and 7 of substantially identical dimensions are chosen.
- the second spacer 7 preferably has dimensions substantially identical to those of the first spacer 1, so that they can be easily assembled to each other by suitable securing means, for example by gluing, welding or screwing using tie rods and nuts, possibly with the interposition of a seal.
- the second spacer 7 also comprises an inlet 8 (here formed 0 in a side wall of its upper part), supplied by a second circuit 9 for supplying a second hot or cold fluid, as well as an outlet 10 (here formed in a side wall of its lower part), connected to said second supply circuit 9 to evacuate the second hot fluid once it has circulated inside the second chamber 6. 5
- a heat exchange wall constituted by a plate 11 formed in a thermally conductive material.
- This plate 11 is interposed, sealed, between the first 1 and 0 second 7 spacers.
- this plate 11 is of metallic type and includes disturbers 15 (shown in FIGS. 8 to 10) intended to promote the heat exchange between the second fluid and the first fluid.
- disturbers can be the result of a deformation obtained by a pressing technology, for example, and therefore they are part of the plate.
- they can also be elements added to a substantially flat plate.
- first 1 and second 7 spacers each have a first side wall 12, 13 open so as to allow the fluids to lick the parallel faces of the plate 11 which closes the first 2 and second 6 chambers.
- Each spacer 1, 7 further comprises a second closed side wall 13, placed substantially parallel to the first open side wall 1.
- the first 12 and second 13 side walls of each spacer could be opened, the second side walls 13 of the two spacers then being closed by a plate of the type of plate 11 forming the heat exchange wall.
- the first 1 and second 7 spacers and the plate 11 interposed between these spacers form a modular block B.
- several modular blocks B can be associated in the same device, either in parallel (as illustrated), or in series, either in parallel and in series. More specifically, in the example illustrated, three modular blocks B1 to B3 are secured to each other and supplied in parallel by the first 4 and second 9 fluid supply circuits.
- the blocks could be arranged so as to operate in series, the outputs 5 and 10 of the first block B1 supplying the inputs 3 and 8 of the second block B2, the outputs of the second block B2 supplying the inputs of the third block B3 and the outputs of the third block B3 supplying the first 4 and second 9 circuits.
- a device of this type could be used to carry out either a mass transfer between the first and second fluids, or a heat exchange and a mass transfer.
- the heat exchange plate 11 is replaced by a membrane chosen according to the type of exchange desired. It may be, for example, a filtration membrane which allows only a unidirectional passage of a given component from the first fluid to the second, for a separation of components or else a mixture of constituents. Such a membrane can be either interposed between the two spacers 1 and 7, or previously fixed on one of the two spacers.
- Such an insert can, for example, be formed a cartridge housing a treatment material such as a catalytic foam or a reactive agent. It can also be a turbulence generator, or else an agitator. Furthermore, when several modular blocks Bi are mounted in series and / or in parallel, the successive chambers may have inserts of different types.
- first or second chambers can also vary from one block to another.
- the (sub) spacers have first and second open side walls.
- the spacers which delimit a chamber (first or second) may be different, one having both open and closed side walls, the other having all open side walls. It is also possible to use first 1 and second 7 identical spacers.
- At least one of the first and / or second spacers may also include injection means (see FIGS. 12 to 15, and 20), such as for example an injector making it possible to introduce into a chosen location of a chamber (of preferably a first chamber 2) a specific product intended, for example, to control a chemical reaction inside said chamber.
- injection means such as for example an injector making it possible to introduce into a chosen location of a chamber (of preferably a first chamber 2) a specific product intended, for example, to control a chemical reaction inside said chamber.
- injectors can be provided in the same spacer, so as to inject one or more different fluids in selected locations (see Figure 15).
- an injector can be used to supply a chemical reaction by reacting at a location chosen according to the type of this reaction.
- Such injectors are particularly suitable for devices equipped with a cooling circuit for exothermic reactions or a heating circuit for endothermic reactions, such as for example those illustrated in FIGS. 2 to 10.
- the device in FIG. 1 could also be used, provided that the intermediate plate 11 is of the electrical type (in this case, the two fluids circulating in the spacers 1 and 7 are the same).
- the device comprises a thick spacer 21, the side walls of which define a first chamber 22, hollowed out so as to allow the circulation of a first fluid.
- the spacer 21 has an inlet 23 connected to a first circuit 24 for supplying the first fluid and an outlet 25 for discharging the first fluid treated out of the first chamber 22.
- This first chamber 22 is delimited by first 26 and second 27 substantially parallel side walls. Of course, these side walls could have different inclinations, for example substantially opposite, relative to a vertical direction.
- the first side wall 26 is shaped so as to define at its external face a second chamber 28 intended to receive a second fluid.
- the spacer 21 therefore comprises a second inlet 29 connected to a second circuit 30 for supplying second fluid and a second outlet 31 for discharging the second fluid from the second chamber 28.
- the device is a heat exchanger which comprises only a spacer 21 and a plate intended to cooperate with the external face of the first wall 26 of the spacer 21 to define the second chamber 28 (or in in other words, ensuring a tight sealing of the chamber 28).
- the end plate 32 can also serve as an input plate for B1, thus allowing complete framing of the second circuit by the first and last channels. Consequently, in this example, the first 25 and second 31 outputs of the first block B1 respectively supply the first 23 and second 29 inputs of the second block B2 and so on, the first 25 and second 31 outputs of the last modular block (here B4 ) being respectively connected to the first 24 and second 30 fluid supply circuits. It is clear that in the example illustrated in FIG. 2, the dimensions of the second chamber 28, and in particular its thickness, are fixed by the arrangement of the external face of the second wall 26 of the spacer 21.
- the device illustrated in FIG. 3 is a variant of the device illustrated in FIG. 2.
- the first wall 26 of each thick spacer 21 is closed, while the second wall 27 of this same spacer is open and closed by a plate 32, for example made of metal.
- the end plate 32 can also serve as an input plate for B1, thus allowing complete framing of the second circuit by the first and last channels.
- a modular block Bi therefore consists here of a plate 32 and a spacer 21.
- the blocks Bi can be mounted in series (as illustrated) and or in parallel as in the example in FIG. 1.
- the device comprises thick spacers 41, of substantially symmetrical constitution, owing to the fact that they comprise first 42 and second 43 side walls which are preferably substantially identical and each delimit by their external face shaped a part at less than a second chamber 46.
- Each spacer 41 comprises, as in the examples illustrated in FIGS.
- each spacer 41 may have other inlets and second fluid outlets, insofar as it defines by the external faces of its first 42 and second 43 side walls, two second chambers 46 (at least partially) in which the second fluid can circulate in parallel and preferably in the same meaning.
- each spacer 41 alone constitutes a modular block Bi.
- four modular blocks B1 to B4 are connected in series, outputs of one supplying inputs of the other.
- the blocks could be mounted in parallel.
- the external face of the first side wall 42 of a first block defines with the external face of the second side wall 43 of the block following a second chamber 46.
- each external face which is not placed at one end of the device defines a "half" second chamber.
- the device of FIG. 4 can also be seen as an assembly of modular “on-blocks” of treatment each consisting of two first spacers 41 and of the plate 53.
- a membrane so as to subdivide into two parts the second chamber delimited by the external faces of the preformed side walls of successive spacers.
- one can envisage, in particular, an exchange of molecules, atoms or ions between the fluids (for example different gases) which circulate in the two parts of a second chamber.
- the device illustrated in FIG. 5A is a variant of the device illustrated in FIG. 4.
- a plate 53 is provided between two thick thick spacers 41 adjacent, with preformed external walls. Consequently, in this embodiment, a modular block Bi is constituted by a spacer 41 and a plate 53.
- Each spacer 41 thus defines a first chamber 45 and two second chambers 56 which are each closed by a plate 53 which belongs to the block next (or previous), or by an end plate of the device as described above with reference to FIG. 4.
- a first fluid circulates in the chambers 45, preferably in the same direction, for example from top to bottom, while a second fluid circulates alternately in the second chambers 56, for example from top to bottom, then from bottom to top, then from top to bottom, etc.
- the device illustrated in FIG. 5B is a variant of the device illustrated in FIG. 5A, in terms of the circulation of fluids.
- a first fluid circulates in the chambers 45, preferably in the same direction, for example from top to bottom, while a second fluid circulates in a second direction, preferably opposite to the first direction, in the chambers 56 .
- the device illustrated in FIG. 6A is another variant of the device illustrated in FIG. 5A.
- the second chambers 56 are delimited by pairs of plates 53, which are placed on either side of the open side walls of thick spacers 61, each defining a first chamber 45 open. Consequently, in this embodiment, a modular block Bi is constituted by a pair of plates 53, a spacer 61 and a plate 53.
- a first fluid circulates in the chambers 45, preferably in the same direction, for example from top to bottom, while a second fluid circulates alternately in the second chambers 56 , for example from top to bottom, then from bottom to top, then from top to bottom, etc.
- the device illustrated in FIG. 6B is a variant of the device illustrated in FIG. 6A, in terms of the circulation of fluids.
- a first fluid circulates in the chambers 45; preferably in the same direction, for example from top to bottom, while a second fluid circulates in a second direction, preferably opposite to the first direction, in the chambers 56.
- the device always includes a spacer 61 whose side walls define a first hollow chamber 62, but this time, the second chamber 66, in which the second fluid circulates, is defined by two plates 64 and 65, of the type used in traditional plate exchangers. These two plates 64 and 65 can be firmly assembled before being assembled to the spacers 61.
- a spacer 61 and the two plates 64 and 65, which define a second chamber 66, constitute a modular block Bi.
- three modular blocks B1 to B3 have been connected in series, but, of course, they could be more numerous, and / or connected in parallel or in series and in parallel.
- the spacer 61 of the first block B1 has an inlet 67 connected to the first circuit 68 for supplying the first fluid, so as to supply the first chamber 62, and an outlet 69 for discharging the first treated fluid out of the first chamber 62.
- the plates 64 and 65 which delimit the second chamber 66, have an inlet 70 connected to a second circuit 71 for supplying second fluid to supply said second chamber 66, and an outlet 72 for discharging the second fluid outside the second chamber 66.
- the spacers 61 have first and second open side walls and intended to be closed by one of the plates 64 or 65 of a previous block, or else by an end plate 73.
- a plate end, serving as an entry plate, can allow complete framing by first and last channels of the second fluid supply circuit.
- an end plate 73 can be replaced by two other plates 64 and 65 which define an additional second chamber 66.
- each thick spacer 61 is constituted by two sub-spacers 61 -a and 61 -b so as to increase the thickness of each first chamber 62 .
- the device illustrated in FIG. 10 is a variant of that illustrated in FIG. 9, in which first thick spacers 61 are provided, constituted (here) by two sub-spacers 61-a and 61-b so as to increase the thickness of each first chamber 62, alternated with second thick spacers 81, constituted (here) by two sub-spacers 81 -a and 81 -b so as to increase the thickness of each second chamber 82, with the interposition of a plate between each first 61 and second 71 successive spacers.
- first thick spacers 61 are provided, constituted (here) by two sub-spacers 61-a and 61-b so as to increase the thickness of each first chamber 62, alternated with second thick spacers 81, constituted (here) by two sub-spacers 81 -a and 81 -b so as to increase the thickness of each second chamber 82, with the interposition of a plate between each first 61 and second 71 successive spacers.
- some chambers formed in spacers can accommodate one or more inserts, and some spacers can be equipped with injectors for the introduction of a specific product intended, for example, to control a chemical reaction inside a room.
- FIGS. 11A to 11D There are shown in FIGS. 11A to 11D, four exemplary embodiments of inserts.
- FIGS. 12 to 15 also show examples of spacers fitted with injectors. More specifically, in FIG. 12 is illustrated an injector 100, of conical type, in FIG. 13 is illustrated a vertical injector 101, of cylindrical type, in FIG. 14 is illustrated a horizontal injector 102, of cylindrical type, and in FIG. 15 are illustrated a first upper horizontal injector 102, of cylindrical type and a second intermediate horizontal injector 103. Furthermore, as mentioned previously, in all the examples of device previously described, the sealing between consecutive spacers or between a spacer and a plate can be provided either by a sealing means (peripheral or O-ring, metallic or not, installed on one of the two elements), or by gluing or welding.
- a sealing means peripheral or O-ring, metallic or not, installed on one of the two elements

- many other materials can be envisaged, such as for example glass, ceramic, or metal (stainless steel, titanium, aluminum, for example).
- the embodiment of these spacers depends on the material or materials used: machining and / or welding and / or molding and / or forming.
- the circulation of the fluid inside the device can be either completely alternating (rising / falling / rising / falling ...), which corresponds to a circulation "in series” as indicated previously, either partially alternating (rising then descending or descending then rising), which corresponds to a “parallel / series” type of circulation. More generally, all the combinations of the series and parallel / series modes can be envisaged (the examples illustrated are only nonlimiting examples). It is also possible to envisage dividing a spacer chamber into two parts, as illustrated in FIG. 16, for example by accommodating inside the chamber a partition 110.
