Definitions
- the present invention relates to a plate heat exchanger and the use of the plate heat exchanger for transferring heat between media.
- Plate heat exchangers contain a package of heat exchange plates through which heat is transferred from one medium to another medium. Adjacent plates form a channel system through which a medium flows.
- a medium is understood to mean a liquid or a gas, although it is not excluded that there are particles in the liquid or the gas.
- sealless In the case of plate heat exchangers, a basic distinction is made between so-called sealless and sealed designs.
- the gaps between the plates are sealed by a fixed connection of the plates, for example by welding or soldering or by the so-called fusion technique.
- sealed plate heat exchangers In the case of sealed plate heat exchangers, the heat exchange plates lie on top of one another at the edges and are separated by seals.
- Such sealed plate heat exchangers are known, for example, from EP 1996889 B1.
- a plate heat exchanger is described from a plurality of plates, the individual plates being stacked and each connected to one another with circumferential seals and a channel system is formed which runs in a meander shape and the side walls of the guide channels have openings. The aim is to improve heat transfer performance and reduce pressure loss.
- the present invention is based on the object of providing sealed plate heat exchangers that can withstand high pressure differences between the media and the environment during operation and that are also stable with respect to temporal pressure fluctuations or jumps in a medium.
- This object is achieved by a plate heat exchanger comprising two heat exchange plates, which form a channel system lying between the heat exchange plates and which is sealed by a sealing element, the channel system comprising a support element and the support element being spaced apart from the sealing element and a support element material from a Material of a heat exchange plate is different.
- the number of plates is not limited to two.
- the specialist selects the number of heat exchange plates according to the desired heat transfer capacity. The greater the number and area of the heat exchange plates, the greater the heat transfer capacity.
- the channel system lies between two heat exchange plates.
- the two mutually facing surfaces of adjacent heat exchange plates define flow channels of the channel system.
- at least one of the two surfaces facing one another is profiled.
- Graphite heat exchange plates and silicon carbide heat exchange plates are often machined by milling on one side, so that only one of the two surfaces facing one another is profiled.
- the channel system is then created by a profiled surface against the smooth surface of the next plate in the stack.
- the two mutually facing surfaces of the two heat exchange plates can also be profiled.
- Embossed plates are preferably profiled on both surfaces, e.g. those made from the F100 material offered by SGL Carbon.
- F100 material is a material that contains graphite particles and fluoropolymer.
- the joint connection between the plates is realized by a detachable joint connection.
- the term releasable is understood to mean that the plates separate from one another without destroying the plates.
- Non-destructive joining connections would be, for example, material connections such as soldering, welding, gluing.
- a sealing element is understood to mean means, e.g. a seal, for hermetically sealing the duct system from the surrounding atmosphere
- a support element is to be understood as an element that lies between the heat exchange plates lying on top of one another and supports them against one another.
- the support element is spaced from the sealing element. This means that the support element and sealing element do not merge into one another, but are elements that are separated from one another.
- the support element is a support connection of the two heat exchange plates. This means that a force acting orthogonally to the heat exchange plate plane on one of the heat exchange plates is partially transmitted via the support element to the other heat exchange plate following in the direction of the force.
- the sealing element can have a circumferential sealing element area. Such a sealing area can be found, for example, in a frame seal as shown in Figure 4 in DE102008048014 A1.
- the sealing element can also be a self-contained, circumferential band or, through overlapping band areas, e.g. band ends, form a band contour that is closed all around. This causes a continuous, reliable sealing of the sewer system from the environment.
- the tape can be in solid or paste-like form, the width, thickness and the sealing element material or the sealing element materials are always coordinated so that a sufficient sealing effect and the lowest possible tendency to creep and at the same time an adequate corrosion resistance for the respective media Sealing element is ensured.
- the sealing element according to the invention preferably comprises a fluoropolymer, for example polytetrafluoroethylene (PTFE). It is also preferred if the support element according to the invention comprises a fluoropolymer, for example PTFE.
- PTFE polytetrafluoroethylene
- the fluoropolymer can be selected from partially and fully fluorinated polymers. Suitable fluoropolymers are, for example, polytetrafluoroethylene (PTFE), ethylene tetrafluoroethylene (ETFE), polyvinylidene difluoride (PVDF), ethylene chlorotrifluoroethylene (ETCFE), tetrafluoroethylene-flexafluoropropylene copolymer (FEP), perfluoroalkoxy polymers (PFA).
- PTFE polytetrafluoroethylene
- ETFE ethylene tetrafluoroethylene
- PVDF polyvinylidene difluoride
- ETCFE ethylene chlorotrifluoroethylene
- FEP tetrafluoroethylene-flexafluoropropylene copolymer
- PFA perfluoroalkoxy polymers
- Fluoropolymers ensure chemical and thermal resistance and tightness, as well as mechanical properties such as good power transmission. It goes without saying that this property profile is fulfilled to different degrees by different fluoropolymers, e.g. PTFE is particularly corrosion-resistant. On the other hand, some other fluoropolymers have a lower tendency to creep.
- the sealing elements and the support elements are preferably made of an identical material.
- the full flexural strength of the heat exchange plates is then available for pressure differences and pressure fluctuations or pressure jumps in the media.
- Another advantage is that the support element and sealing element can be produced in a particularly simple manner from spaced-apart sections of a precursor material. Examples of precursors are:
- sealing paste such as the commercially available paste Chesterton® GoldEnd® 900 containing the fluoropolymer particles
- a PTFE sealing tape e.g. the commercially available GORE® sealing tape series 500
- the support elements are pressed between the heat exchange plates.
- the thickness of the support element is at most 10%, preferably at most 4% of the width of the support element. This has the advantage that the plate heat exchanger has an even greater stability against pressure jumps.
- the sealing elements according to the invention have a defined thickness.
- the thickness of the sealing element is preferably at most 10%, preferably at most 4% of the width of the sealing element. This means that the plate heat exchanger can withstand exceptionally high operating pressures over the long term.
- the thickness of the support element and / or the sealing element is preferably between 0.01 and 0.5 mm.
- the width of the support element and / or the sealing element is preferably at least 3 mm, particularly preferably between 3 and 20 mm. This also results in optimal tightness and stability against high pressure differences.
- the support element can be in the form of strips.
- strip-shaped is to be understood as meaning that the support element has a defined width and defined length, where the length is, for example, at least five times the width.
- the support element does not necessarily have to run straight. This has the effect that the force is transmitted via the surface of the strip-shaped support element to the closest heat exchange plate.
- the support element can also be a support disk.
- a support disk is a support element whose outline is at most twice as long as the outline of a circle of the same size.
- support disks can be produced by using a paste as a precursor material and applying this in blobs at specific points. During the pressing process, an approximately round, flat support disc is formed from the material in front of it. The punctual application that takes place in this way means that less material is required for the support elements and the support elements in the areas of the pressure difference peaks can be attached sporadically. A deflection of the heat exchange plates can therefore be counteracted in a targeted manner with minimal use of support material where the risk of material failure is greatest.
- the heat exchange plates can advantageously have graphite and / or ceramic and / or metal.
- metals or metal alloys such as steel or, in the case of particularly corrosive media, ceramic materials such as silicon carbide or fiber-reinforced ceramic materials or graphite can be used as the material for the plates.
- a channel in the channel system can furthermore comprise a flow-breaking element.
- Flow-breaking elements are elements that prevent the medium from flowing in a straight line in the direction of the channel. This causes a turbulence in the flowing medium and thus that the efficiency of the heat transfer is increased. So even at lower flow velocities of the medium there is a turbulent flow.
- the plate heat exchanger comprises three heat exchange plates, which form a first channel system located between the first heat exchange plate and the second heat exchange plate and a second channel system located between the second heat exchange plate and the third heat exchange plate, the first channel system being sealed by a first sealing element and a the first support element comprised by the first channel system is arranged in alignment with a second support element comprised by the second channel system.
- Aligning here means that the outlines of the first and second support elements at least partially overlap. Overlapping is present when the outlines run in such a way that at least one straight line oriented orthogonally to the plates extends through both outlines.
- This means that the support elements are arranged in an axis which is perpendicular to the surface of the heat exchange plates.
- the force acting along the axis is on a heat exchange plate acts via the support element on another heat exchange plate and from this in turn transferred via the further support element to the heat exchange plate following in the direction of force.
- the invention also relates to the use of the plate heat exchanger according to the invention for transferring heat from one medium to another medium, one medium being corrosive or both media being corrosive.
- Corrosive means that the medium can impair the functions, through chemical reaction, of materials, e.g. steels or other construction materials, that come into contact with the medium.
- These corrosive media can be selected from hydrochloric acid, hydrofluoric acid, sulfuric acid, phosphoric acid and monochloroacetic acid.
- the invention also relates to the use of the plate heat exchanger according to the invention for the transfer of heat, the pressure difference between a medium and the environment and / or the pressure difference between two media between which heat is transferred, at least 7 bar, preferably at least 9 bar, particularly preferably at least 11 bar, very particularly preferably at least 13 bar, extremely preferably at least 17 bar, for example at least 21 bar.
- the invention also relates to a method in which, in a plate heat exchanger according to the invention, heat is transferred from one medium to another medium, at least one of the two media in physical contact with a food, a pharmaceutical product or a semiconductor material or in contact with a Precursor of the food, the pharmaceutical product or the semiconductor material is brought.
- Figure 1 shows a portion of a heat exchange plate in perspective Dar position
- Figure 2 shows a region of a heat exchange plate in perspective Dar position with applied portions of a precursor material for fiction, contemporary support elements
- Figure 3 shows a cross section of a heat exchange plate with applied front runner materials for sealing elements and for support elements according to the invention
- Figure 1 shows a portion of a typical heat exchange plate 1 for a plate heat exchanger.
- the heat exchange plate is profiled on the surface visible here, so that in the stack with a further heat exchange plate arranged above it (not shown here), a channel system 2 results, into which a medium can be introduced through a through opening 3.
- the channels 5 comprised by the channel system are delimited by 4 webs.
- the same nickelaus exchange plate 1 is shown in the same perspective, sections of a support element precursor material 6 are additionally arranged on the webs 4.
- a support element precursor material 6 is also shown in the section shown in FIG.
- the heat exchange plate from Figure 3 is similar to the heat exchange plates from Figures 1 and 2, but the webs 4 here have a trapezoidal cross-section.
- a sealing element precursor material 7 is also provided, which runs around the outer edge of the surface.
- Embodiments Two small test plate heat exchangers (SiC PHX P05) with 10 silicon carbide heat exchange plates each were built. The dimensions of the panels for type P05 are 230 x 620 mm. The heat exchange plates each had a built-in profile and openings for the media. The two test plate heat exchangers only differed in additional support elements according to the invention, which were only inserted in the second test plate heat exchanger.
- a sealing cord (PTFE-based, approx. 4 mm thick) was applied around the channel systems between adjacent heat exchange plates and around the passage opening through which the other medium flowed.
- the sealing cord served to limit the areas through which the two media flowed from one another and to limit these areas from the surrounding atmosphere.
- test pressure of 8 bar was achieved.
- a test pressure of 12 bar was achieved with the second test plate heat exchanger.
- the first leakages in the second test plate heat exchanger did not occur until a test pressure of 13 bar.
- test pressure could already be increased by 50% in this first, very simplified test setup.
