    专利说明:

    Various methods are used in separating water vapor from a fluid; such as rotating wheels with moisture capture or plate heat exchangers with semi-permeable membranes. In gas drying technology, pipe bundles made of materials such as Nafionnf are used. However, these different methods for removing water vapor from fluids have certain disadvantages; rotary replacement units are equipped with moving parts that incur additional maintenance costs. In addition, rotary replacement units increase the risk of contamination between the air streams.
    Plate heat exchangers show low efficiency when it comes to enthalpy and Nafionm pipelines are expensive.
    Those who manufacture these technologies are all trying to find the most cost-effective way to achieve these effects and therefore different procedures are being developed. In conventional plate-based heat and moisture exchangers, the layer of the exchanger / exchange unit often consists of spacers or spacers or a support structure on which a diaphragm has been laid. Such structures are common but it has not been possible to get any high cost efficiency due to which can be expensive due to the need for spacers, use the material.
    The spacers also increase the total weight of the replacement unit.
    Due to the weight, more support is required in the assembled condition and increased weight also increases the risk during handling during maintenance. Transport costs also increase at higher weights.
    In some gas drying technologies, a myriad of small tubes are used to provide a large area for moisture exchange / moisture exchange along with good flow properties through the tubes, while the gas flow properties outside the bundle are largely neglected, for example by often lacking sufficient space for flow between the tubes. .
    The tubes in a bundle are usually used in conjunction with another fluid stream flowing countercurrently or transversely to the tubes but outside and between the many tubes.
    When individually manufactured tubes of very small diameter are used, the production costs become high because it is technically difficult to manufacture small tubes and refine them into a product, and consequently the end product will be expensive.
    Another disadvantage when the pipes are packed in bundles in current contemporary products is that no satisfactory clearance is provided for the flow properties between the pipes.
    SUMMARY OF THE INVENTION The present invention relates to a method of manufacturing multiple channels for use in a device for exchanging solutes between at least two fluid streams which overcomes the above-mentioned disadvantages and shortcomings. A first and a second sheet are included in the device. The method comprises the steps of providing at least one of the first and second sheets with at least one profiled surface, and joining the first and second sheets. As a result, channels are formed through the shape of the profiled surface.
    The present invention provides a method which enables the production of multiple thin channels at very low production costs. In addition, the method provides an alternative way of fabricating multiple channels of infinite variation using favorable flow patterns.
    According to another embodiment, the method comprises the further step of providing each of the first and second sheets with at least one profiled surface and joining the first and second sheets with the profiled surfaces facing each other, whereby the channels are formed by the profiled surface shape.
    According to another embodiment, in which a plurality of sheets are included, the method comprises the further step consisting in joining the plurality of sheets, whereby channels are formed in multiple layers through the shape of the profiled surfaces.
    According to another aspect of the present invention, there is provided an apparatus for exchanging solutes between at least a first and a second fluid flow. The device comprises at least a first and a second sheet, the first sheet being provided with at least one profiled surface.
    The first and second sheets are joined together, whereby channels are formed through the shape of the profiled surface.
    The device according to the present invention is particularly useful for exchanging a substance from a first fluid flow to a second fluid flow, for removing or separating the substance from the first fluid flow.
    According to another embodiment, each of the first and second sheets is provided with profiled surfaces and the first and second sheets are joined to the profiled surfaces facing each other.
    According to another embodiment, the sheets are provided with profiled surfaces which are mirrored towards each other.
    According to another embodiment, the cross-section of the channels varies along the length of the device.
    According to another embodiment, the number of channels varies along the length of the device.
    According to another embodiment, the device further comprises a plurality of sheets stacked in multiple layers.
    According to another embodiment, the sheet material has a great ability to dissolve water.
    According to another embodiment, the sheet material has a pore size between 0.1 - 50 nanometers.
    According to another embodiment, the sheet material has a pore size between 50 - 500 nanometers.
    In another embodiment, at least one of the sheets is hydrophobic.
    In another embodiment, at least one of the sheets is hydrophilic.
    According to yet another embodiment, at least one of the sheets is of metal.
    The large exchange area provided by a plurality of channels together with good flow properties between the layers provides the best possible situation for transmission by diffusion between the fluid streams.
    The present construction enables an arbitrary distance between the layers as required. The flow properties between the layers can also be adjusted by increasing the distance between the layers or by alternating the arrangement of the layers.
    A further advantage, for example in the case when a fluid is to be dried, is that a larger air flow can flow outside the channels, or between the layers in embodiments provided with more than one layer, whereby the fluid inside the channels is dried more efficiently. By suitable design of the distance between the layers, the flow rate between the layers can be optimized for the application.
    The present invention provides a device that enables a countercurrent construction with a tight design and no need for separate spacer material to allow flow across the sheets. The device also provides exceptionally good flow properties between the layers through its construction with multiple channels and construction with stacked layers with adjustable distance between the layers. The integrated channels also lead to less maintenance and lower risk of wear as there is no abrasion due to vibrations between the sheets and the support structures.
    Another advantage is that the device is cheap to manufacture with automatic separation of individual channels and with good and independently adaptable flow properties on the outside. The present invention further provides a solids exchange device which eliminates the need for additional support structures between the sheets while at the same time providing countercurrent flow means, which significantly improves efficiency over conventional technology.
    Further preferred embodiments are defined by the subclaims.

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Below, a detailed description of a preferred embodiment of the present invention will be given.
    Fig. 1 shows a device for replacing water vapor according to the prior art. In conventional technology, a corrugated material or a flow distribution element between planar sheets of permeable material is used to define channels and flow direction and to provide a uniform spacer for separating the layers. In some examples, the sides of the layers face downward for This construction is to provide spacers. always limited to a cross-flow design.
    Fig. 2 shows a sheet 3 with a profiled surface 5 according to the present invention. To create the shape of the profiled surface 5, many different methods can be used in the manufacture. The sheet may, for example, be a corrugated sheet. As a further example, a sheet of a material can be heated to such a temperature that it can be deformed and then cooled after it has been formed over a mold / body, thereby allowing the mold to solidify. Once it has been permanently deformed, the shape will remain. Another way is to let a large number of very thin threads fall randomly over a shape / body e.g. by electrospinning, to create a shape which, once solidified, retains its shape even when deformed. Yet another way of creating the shape of the profiled surface 5 is to cut out channels with favorable flow patterns in one or both sides of a sheet of solid or porous material. The material in sheets 3, 4 may be semi-permeable, or permeable to certain substances or solutes.
    The sheet material can be either porous or solid or both.
    The methods described above are particularly suitable when the dimensions of the channels 1 are small. Using these methods, small ducts with a cross section of only a few millimeters can be produced easily and cost-effectively.
    The shape of the profiled surface and thus the cross section of the channel formed by the surfaces can vary depending on the desired flow properties. The cross-sections of the channels can be, for example, circular, hexagonal, square or triangular.
    A first and a second fluid can flow countercurrently relative to each other, inside and outside the channel 1, respectively.
    The fluids in the channel can be a gas or a liquid. Fig. 3 shows another sheet 3 with a profiled surface 5 according to an embodiment of the invention. The sheet is further provided with openings to facilitate the flow between the layers 7 when a plurality of layers are joined in multiple layers 7.
    Fig. 4 shows two sheets 3, 4 with profiled surfaces 5 which are joined according to the present invention. By providing a sheet of a base material with profiled surface 5, for example as shown in Fig. 1 and by joining two such sheets 3, 4 with opposite and preferably mirror-shaped profiled surfaces 5, a plurality of small channels 1 can be formed in a procedure that can be easily automated.
    Joining of the sheets 3, 4 can be effected, for example, by welding, gluing or melting or with any other suitable adhesive storage with which the two profiled plates could be hermetically joined.
    The sheets 3, 4 are provided with a profiled surface 5, whereby channels with 1 with circular cross-sections are provided. The channels 1 may have any other suitable shape, for example oval, hexagonal or square.
    Fig. 5 shows a plurality of joined sheets 3, 4. When stacked as shown in the figure, the sheets 3, 4 form multiple layers 7. Such a design leads to a low pressure drop when the fluid flows from one side to the other, whereby it ensures and maintains the flow properties of the channels and an undisturbed flow between the layers 7, outside the channels 1.
    Figs. 6 and 7 show sheets 3 with alternatively profiled surfaces 5. Figs. 8 show a plurality of sheets 3, 4 which are joined in multiple layers 7. The layers 7 are displaced relative to each other, whereby a device with a plurality of layers 7 of alternating configuration provided. An alternating configuration reduces the distance between the layers 7 and thus increases the total area of the configuration per unit volume, and the unit can thus be made more compact while maintaining the same surface area.
    Fig. 9 shows two sheets with a profiled surface which are joined together.
    Fig. 10 shows a sheet 3 with profiled surfaces 5 which is joined to a sheet with a smooth surface. Thereby, channels 1 are provided which have a semicircular cross-section.
    Fig. 11 shows a sheet with an alternatively profiled surface 5.
    The sheet is also provided with a plurality of openings 6 to facilitate flow between the sheets 7 when a plurality of sheets 3, 4 are joined in multiple layers 7.
    To separate the flow inlet, openings can be cut out between the channels. This gives inlet channels which are perpendicular to the main direction of the channels, whereby the flow outside the channels, or in the case of multiple layers, between the layers, is separated from the inlet point of the flow inside the channels.
    If the design of the multiple layers 7 is alternating, the same method can be used for a diagonal channel, which is perpendicular to the channels for feeding the flow between the layers 7. The profiled surfaces 5 can be formed by any suitable method, for example by heating the sheets, deforming them whereby the surfaces are profiled, and then cooling them whereby the shape of the profiled surfaces remains in its deformed shape. Another example is to allow a plurality of thin threads to fall randomly over a body with a profiled surface, thereby creating a sheet with a profiled surface, which will retain its shape once it has solidified. Additional alternatives may be to cut channels in one side or in both sides, on a first and a second sheet of solid or porous material. Furthermore, the profiled surface can be achieved by applying a pattern of plastic or other suitable material to the sheets.
    In addition, the openings 6 can be cut between the channels 1 to provide an inlet which distributes the flow from a direction perpendicular to the channels 1, between the layers 7.
    This provides an undisturbed flow perpendicular to the main direction of the channels, whereby the flow between the channels is separated from the inlet point of the flow inside the channels. If the configuration of the layers 7 is alternating, the same method can be used for a diagonal channel, which is perpendicular to the channels for feeding the flow between the layers 7.
    To distribute the flow evenly and easily between the layers 7, openings 6 can be cut out either between the ends of the channels (mainly for flow distribution), or at intervals along the entire length of the channels, which provides a simple means for pressure equalization and a simple flow path.
    To provide a bundle of transverse flow or countercurrent flow channels, uniformly spaced openings 13 may be cut between the channels to obtain an undisturbed flow between the channels from two directions (from top to bottom or from side to side), both of which are perpendicular to the main direction of flow. inside the channels.
    The invention has mainly been described above with reference to some embodiments, but as those skilled in the art will readily recognize, embodiments other than those described above are also possible within the scope of the invention, as defined in the appended claims.
