  • Such heat exchangers are known in various embodiments.
  • the often made of stainless steel or another metal that is as corrosion-resistant as possible existing pipes are passed through tube sheets at their ends and connected to the tube sheets by soldering or welding.
  • pipes from z. B. Stainless steel is corrosion-resistant according to conventional standards at least not when used as a heat exchanger between such gases or liquids that contain particularly aggressive components, such as z. B. sulfurous acid.
  • heat exchangers Especially in the area of flue gas desulfurization and Waste incineration, however, requires heat exchangers that also last can withstand acidic gases, especially when falling below the Acid dew point.
  • the invention has for its object one from pipes composite heat exchanger suitable for aggressive media create the pipe side due to low pressure drops and a low Tendency to contamination.
  • the tubes are plastic tubes with tube walls forming a zigzag pattern in longitudinal section, the zigzag patterns on the inside and outside of the tube corresponding to each other, and that the flanks of the zigzag pattern pointing obliquely downwards on the inside of the pipe have a smaller angle to the pipe center axis than the flanks pointing obliquely upwards.
  • Plastic pipes designed in this way are characterized by a relatively high strength from, because of the on the inside and outside of the pipe Corresponding zigzag pattern with sufficient Strength can be achieved with relatively small wall thicknesses.
  • plastic pipes for use in a heat exchanger as part of the flue gas desulfurization of a power plant can such plastic pipes with a nominal width of up to 120 mm and one Wall thickness of only 0.4 mm can be used.
  • zigzag shaped Design of the tube walls is sufficient despite the small wall thickness Resistance to the flow ridges prevailing in the heat exchanger and possibly vibrations reached.
  • flanks of the zigzag pattern with each other alternating flanks of different sizes ensure that the pressure drops are only slight when flowing through the pipes. Also the The tendency to contamination is low, as flow turbulence is generated an undesirable deposit of deposits on the inside of the pipe prevent.
  • the angle is on 1.5 to 2.5 times the inside of the pipe with flanks pointing diagonally upwards the angle of the flanks pointing obliquely downwards on the inside of the pipe is.
  • the zigzag pattern can be designed in a ring shape, that is to say with the circumference flanks of the tube closed.
  • the tubes be made of a melt-weldable fluoroplastic, preferably made of PFA (Perfluoro-alkoxyalkane) or MFA (trifluoro-metoxy-perfluoro-alcoxy polymer).
  • PFA Perfluoro-alkoxyalkane
  • MFA trifluoro-metoxy-perfluoro-alcoxy polymer
  • the tubes in vertical longitudinal direction of the chamber extend that at a vertical distance to horizontal support elements are attached to the tube sheet in the chamber with which the tube outer sides of the tubes are positively connected, and that the Support elements are provided with recesses for each tube, which the Pipe outside of each pipe only on a part of its circumference in enclose in a positive manner.
  • plastic pipes with corresponding, wave-like Structures on the inside and outside have a high radial strength Direction, d. H. against pressure, but in the longitudinal direction behave rather flexibly.
  • the individual pipes to avoid vertical arrangement are therefore in the chamber of the Fixed heat exchanger horizontal support elements with which the Pipe outer sides of the pipes are positively connected.
  • the assembly of the heat exchanger and in particular the positive integration of the pipes in the support elements significantly simplified. This also contributes if the support elements are horizontal strips, which too Both sides are provided with recesses for pipes.
  • the pipe ends are positively fixed in the tube sheet, the positive connection by the Zigzag shape of the pipes is achieved.
  • This enables simple and Inexpensive connection technology, being particularly preferred Design in the opening of the respective tube end Tube bottom is a retaining ring surrounding the tube end is attached, and the Retaining ring is provided on its inner edge with an all-round structure in which the zigzag structure of the outside of the pipe interlocks.
  • the tube sheet at least on the chamber facing side is plastic coated or plastic coated.
  • the tube is preferably plastic-welded to the plastic layer.
  • the tube sheet can be divided into segments is designed, and that the segments are provided with recesses that the Pipe outside of the respective pipe on half of its circumference enclose positively. This enables a particularly simple attachment the tube ends in the respective tube sheet.
  • the heat exchanger shown in FIG. 1 and in cross section in FIG. 2 is designed in the manner of a tube-bundle heat exchanger with a chamber 2 penetrated by the individual tubes 1 and inlets and outlets for the two media involved in the heat exchange.
  • the first medium enters the heat exchanger via the inlet m 1e and leaves it via the outlet m 1a .
  • the distribution of this first medium takes place via hoods 3 attached at the top and bottom and with flow through the individual, vertically arranged tubes 1 of the heat exchanger.
  • the second medium involved in the heat exchange passes through the inlet m 2e into the heat exchanger, flows through the interior of the chamber 2 twice under deflection and leaves the heat exchanger again via the outlet m 2a .
  • the second medium is guided in cross-countercurrent flow, but cross-flow or countercurrent flow is also possible.
  • the pipes 1 are fastened in the region of the inlet m 1e arranged at the top and the outlet m 1a arranged at the bottom on the horizontally extending pipe plates 4 which, like the pipes 1, therefore separate the two media involved from one another.
  • the tube 1 is a plastic tube made of a melt-weldable fluoroplastic, for example made of PFA (perfluoroalkoxyalkane) or MFA (trifluoro-metoxy-perfluoro-alcoxy polymer).
  • the plastic tube is shaped in the manner of a corrugated tube, the zigzag-shaped shafts 5, as can be seen in FIG. 3 in the form of a drawing, on the inside and outside of the tube corresponding to one another with a constant wall thickness d.
  • This wall thickness d is between 0.25 and 0.75 mm, for example approx. 0.4 mm for a pipe with a nominal diameter of up to 120 mm.
  • the ratio between the maximum pipe outside diameter d a and the minimum pipe inside diameter d i is between 1.2: 1 and 1.5: 1.
  • the zigzag-shaped waves 5 each consist of a longer one Edge 6 and a shorter edge 7 together, which are in one another Stand angle that is about 90 °.
  • the in relation to the pipe central axis 1a measured angle ⁇ of the diagonally pointing upwards on the inside of the tube, shorter edge 7 is 1.3 to 2 times the angle ⁇ on the Inside of the pipe towards the longer flank 6, which points obliquely downwards.
  • the ratio of the height H of the longer flank 6 to the height h of the shorter edge 7 between 2: 1 and 4: 1, preferably 3: 1.
  • the smaller angle ⁇ has the advantage that the tubes 1 move upwards flow flowing through at the bottom can nestle against the flanks 6.
  • the shorter flanks 7 in turn lead to turbulence formation in this area and cause that in the area of the flanks 7 no deposits on the Can fix the inside of the pipe.
  • Fig. 3 is the definition of a smooth pipe end 8 in the upper tube sheet 4 shown. A corresponding determination can also be made in the lower tube sheet be provided.
  • the tube sheet 4 is both on its top, as well as on its underside is provided with a plastic layer 9a, 9b. In the area each through hole to the bushings of the tube are the two Plastic layers 9a, 9b formed overlapping. On the top circumferential Edge of the through hole is a weld 10 for gas or liquid-tight connection of the pipe end 8 with the plastic layer 9a drawn.
  • FIG. 6 Another embodiment of the connection between tube 1 and tube plate 4 is shown in Fig. 6.
  • the through opening 11 is in this case in diameter slightly larger and offers space for a retaining ring 12, which is both with the upper plastic layer 9a, as well as with the lower plastic layer 9b is welded.
  • the retaining ring 21, which is also preferably made of Fluoroplastic, such as PFA or MFA, is marked on the inside with a circumferential structure 13 provided in the undulating tube outside intervenes positively.
  • the structure 13 of the retaining ring 12 also has a zigzag shape Wave valleys and wave crests corresponding to the corresponding one Contour of the tube 1.
  • this is on top of the tube sheet 4 arranged plastic layer enlarged to a plastic plate 14. This is provided with an inner edge 15 which fits into the structure of the External surface of the tube 1 engages.
  • Fig. 2 shows that the tube bundle with certain vertical intervals horizontally extending support members 17 is secured.
  • the support elements 17 are attached in a suitable manner in the chamber 2. Details of the Support elements 17 can be based on FIGS. Explain 4 and 5. After that there is each support element from a horizontally extending ledge to both Sides is provided with recesses 18 for the tubes.
  • the recesses have, since the tubes in the embodiment have a circular cross section also have the contour of a circular section. In this way each recess 18 encloses the outside of the tube 1 in question part of its scope.
  • each tube 1 is form-fitting in the vertical direction coupled with a total of two support elements 17 so that the tubes in the area of Do not make any horizontal or vertical movements can.
  • the plastic pipes described enable material savings in the small wall thickness and because of the better heat transfer value, which results, inter alia, from the increased turbulence of the gases on the flanks 7 of the plastic pipes. Furthermore, due to the undulation of the plastic pipes, their surface area increases considerably, depending on the ratio d a / d i . With the same performance, the heat exchanger can therefore be made smaller and more compact.
  • FIG. 9 shows a variant of the tube sheet 4.
  • This consists of individual segments 19 arranged parallel to one another in the same plane. It is similar to the support elements already explained above also in the segments 19 around horizontal strips that go to both sides Recesses 20 are provided for the tubes.
