Definitions

  • the invention relates to a high pressure plate heat exchanger.
  • This has a plate pack, which has media flowed through first and second channels, which are arranged in cross-flow, or in the case of multi-path in the cross-countercurrent.
  • the first channel provided for the first medium are formed in a tubular manner between individual plates connected to a pair of plates and the second channel provided for the second medium in a wave form between pairs of plates connected to a plate stack.
  • a plate pack of the type described above is from DE 43 43 399 A1 known.
  • a plate heat exchanger with flowed through in cross-flow channels is disclosed, which are formed for the one medium wave-shaped between each connected to a plate pair of individual plates and the other medium tubular between the assembled into a plate stack plate pairs.
  • the individual plates for channel formation are equipped with a plurality of parallel rows of aligned in the flow direction of a medium cam or embossed support structures, which are formed offset from each other in the longitudinal direction from row to row.
  • a plate heat exchanger from the DE 43 43 399 A1 previously known type has proven itself in everyday practice. However, for the high-pressure application, ie for media pressures of greater than 25 bar, the previously known constructions are not suitable. This particular not because the prior art plate heat exchanger for higher pressures do not have sufficient mechanical stability and deform at higher pressures beyond the allowable level.
  • US3610330 A and WO2010149858 A1 disclose high pressure plate heat exchangers each having a plate pack disposed in a pressure space provided by a housing. It is therefore the object of the invention to propose a plate heat exchanger suitable for high pressure applications.
  • the invention proposes a high-pressure plate heat exchanger with a rectangular plate pack, which is arranged in a pressure chamber provided by a housing, wherein the plate pack of media through-flowable first and second channels, which are arranged in cross-flow and tubular for the first medium between formed into a pair of plates interconnected individual plates and the second medium undulating between interconnected to a plate stack plate pairs, said tubular channels formed in the longitudinal direction parallel to the longitudinal edges of the individual plates and the individual plates along their longitudinal edges together to plate pairs and the plate pairs along their transverse to the longitudinal edges of the individual plates extending edges are joined together to form a plate stack, wherein the tube side for the first medium and the shaft side as a pressure side for the second Serve medium and the housing has tube side of the plate
  • the second medium under pressure is to be guided on the shaft side of the plate pack.
  • the tube side of the plate package carries the first, under reduced pressure medium.
  • the tube-side forming tubular channels extending transversely to the longitudinal direction of the plate package forming individual plates.
  • the transverse extent of a single plate is limited by the width of the embossing tool, whereas a quasi-endless, that is arbitrarily selectable extent in the longitudinal direction is possible. It has been found in practice that the tube side of prior art plate heat exchangers can be achieved in high pressure applications with a view to a desirable manner Heat transfer is too short.
  • the embodiment of the invention provides a remedy.
  • a plate stamping rotated by 90 degrees is proposed so that the tube side, i. the tubes run in the longitudinal direction of the plate.
  • the channels formed for the first medium in a tubular manner between individual plate plates connected to one another are formed parallel to the longitudinal edges of the individual plates.
  • Plate heat exchangers unlike, for example, tube bundle heat exchangers, are comparatively unstable to pressure.
  • the pressure is applied too high, bulging of the individual plates and / or tearing of connection points existing between the individual plates may occur.
  • the plate pack is surrounded in the intended use of a pressure prevailing in the pressure chamber support pressure, which acts as a back pressure on the plate package.
  • the construction according to the invention proves to be advantageous in this respect in that pressure retaining plates or package side walls are to be designed only with reference to the comparatively low pressure of the tube side, ie the first medium, which means that they are used unchanged in their design compared to the prior art can be, and this at the same time suitability for a high-pressure application in the context of the invention.
  • the housing which provides the pressure chamber is preferably spherical in shape and / or circular with respect to at least one cross section for receiving the pressures prevailing in the operating case, deviating from the rectangular shape of the plate package.
  • the prevailing pressures housing on the other hand allows the media supply to a parallelepiped plate pack, is further provided with the invention constructive that the housing has tube side of the plate package subsequent flange cover, which are at least partially spherical. This ensures structurally that in the transitional, that is, bonding area in the plate stack housing side voltage peaks are avoided, so that with sufficient safety margin comparatively high pressures can be absorbed, while minimizing the required housing wall thicknesses and plate thicknesses.
  • a housing providing a pressure space which projects the outside of the shaft, i. to the surrounding atmosphere through a cylindrical shell and the tube side by a spherical sheath separates, which are avoided as a result housing side voltage peaks in the transition region from the shaft side to the tube side.
  • the inventive design makes it possible for the first time to use plate heat exchanger in the high pressure area, namely at working pressures in terms of the second medium of about 50 bar, preferably from about 60 bar, even more preferably from about 100 bar, up to 120 bar.
  • Previous designs do not allow such printing applications.
  • the working area of previously known constructions ends rather at a pressure of about 20 bar, possibly of about 30 bar. Pressures of over 30 bar, let alone 60 bar and more are not possible with the previously known embodiments.
  • the pressure range of more than 120 bar possible with the embodiment according to the invention is surprising, without restriction by differential pressures, since the thickness of the exchanger plates used on the one hand and the housing wall thickness on the other hand are comparatively thin.
  • the wide pressure application range of the high-pressure plate heat exchanger according to the invention results as Synergy effect from the explained individual features.
  • connecting wedges are arranged in the corner regions of the plate stack between two adjacent plate pairs. These connection wedges are preferably connected to the adjacent pairs of plates by positive engagement by welding.
  • the connecting wedges serve two purposes. On the one hand, a stabilization of the entire plate package construction is achieved. On the other hand, the connecting wedges are used for fluidic separation of the shaft and tube sides.
  • the individual plates provide embossing sections as known per se from the prior art.
  • the individual plates are provided with a plurality of parallel rows of longitudinally extending embossing sections, and embossing sections of adjacent rows are aligned with one another in the longitudinal direction.
  • FIG. 1 can be seen in a side view of a high-pressure plate heat exchanger 1 according to the invention.

  • a plate pack 4 is arranged, which for the sake of clarity in FIG. 2 is shown only schematically.
  • the plate pack 4 is formed from individual plates 14.
  • two individual plates 14 together form a plate pair 15 and a plurality of plate pairs 15 coupled to one another constitute a plate stack 16.

  • the individual plates 14 are each formed identically and connected in mirror image to each other to a pair of plates 15. This connection preferably takes place cohesively by welding, along the longitudinal edges 17.
  • first tubular channels K1 are formed between the individual plates 14 forming a plate pair 15, specifically for the medium M1 participating in the heat exchange in the intended use.
  • the second medium M2 is the pressurized high pressure medium.
  • each individual plate 14 with a plurality of parallel rows of extending in the direction of the longitudinal edges 17 embossing sections 21st Mistake. These embossing sections 21 of adjacent rows are offset from one another in the longitudinal direction, whereby surface supports between adjacent individual plates 14 result in a row between successive embossing sections 21.
  • connecting wedges 20 are arranged between the individual plates 14 adjacent plate pairs.
  • these connecting wedges 20 separate the shaft side from the tube side in the inlet and outlet region of the media M1 and M2 and, on the other hand, serve to stabilize the overall plate package 4 as a whole.
  • the housing 2 is formed from a ring portion 7 and two flange 8 and 9.
  • the flange cover 8 and 9 each provide an opening 10 for the tube side, which are formed in correspondence with the geometric configuration of the plate package 4 and serve to receive the plate package 4.
