Definitions

  • the invention relates to a heat exchanger with the features the preamble of claim 1.
  • Such a heat exchanger is from DE-PS 20 33 128 known.
  • this known heat exchanger is the guide jacket open on both sides and in the middle with a feed connector provided for the jacket-side medium.
  • the supplied medium is distributed on the inside of the guiding jacket on both sides and flows partly in countercurrent and partly in Direct current to the pipe-side medium.
  • jacket-side medium in the annular space between the guide jacket and the outer pressure jacket, from which it is subsequently attached is dissipated. In this way it is achieved that the Pressure jacket not in medium with a high inlet temperature Touch comes.
  • the invention has for its object a U-tube heat exchanger to create, where the final temperature of the influenced on the jacket side and the pressure jacket can be protected against excessive temperature stress.
  • the heat exchanger shown is preferably used by cooling of hot gases from an ammonia or a Methanol production plant or from a coal gasification plant with overheating of steam as a cooling medium.
  • the heat exchanger consists of a pressure jacket 1, the one Encloses bundle of U-shaped tubes 2.
  • the pipes 2 are inserted into a tube sheet 3, which with the pressure jacket 1 connected is.
  • On the side facing away from the tubes 2 The tube sheet 3 is an inlet chamber 4 with a Inlet connection 5 for the supply of a heat exchange medium, e.g. B. steam is provided.
  • Inside the entry chamber 4 an outlet chamber 6 is arranged which is connected to the tube sheet 3 connected and closed off from the inlet chamber 4 is.
  • the outlet chamber 6 is provided with an outlet nozzle 7 provided, which is led out of the inlet chamber 4.
  • the U-shaped tubes 2 are aligned so that the Entry ends on a pitch circle and exit ends on lie in another pitch circle.
  • the flow direction of the medium on the pipe side can also be reversed.
  • the exit chamber 6 with unchanged Inlet chamber 4 is circular in cross section, so that they are now on the larger pitch circle Outlet ends of the tubes 2 open into the outlet chamber 6.
  • the pressure jacket 1 is on the tube plate 3 facing away from the end Heat exchanger with a feed pipe 8 for the feed a heat exchange medium, e.g. B. of hot gas from a Ammonia or a methanol production plant or from one Provide coal gasification plant.
  • a heat exchange medium e.g. B. of hot gas from a Ammonia or a methanol production plant or from one Provide coal gasification plant.
  • a discharge pipe 9 for the discharge of the heat exchange medium provided.
  • the feed pipe 8 is connected via a feed channel 10 a one-sided open central tube 11 connected in the Longitudinal axis of the heat exchanger arranged and from the tubes 2nd is surrounded.
  • the central tube 11 ends near the Tube bottom 3.
  • a cylindrical separating jacket 12 is arranged between the legs of the U-shaped curved Tubes 2.
  • This Partition jacket 12 is connected to the tube sheet 3 and extends up to to the reversing bends of the U-shaped tubes 2.
  • the outer Legs of the tubes 2 are surrounded by a guide jacket 13, the forming an annular space 14 at a radial distance of the pressure jacket 1 is arranged.
  • the guide jacket 13 is on tightly connected at one end to the central tube 11 and sufficient with its open end close to the tube sheet 3. In the of the central tube 11 and the guide jacket 13 enclosed space are arranged perpendicular to the tubes 2 baffles 15.
  • the medium flowing through the feed pipe 8 flows through the central tube 11 is in the vicinity of the tube sheet 3 deflected, flows through the space between the Central tube 11 and the separating jacket 12 is on the deflected closed end of the guide jacket 13, now flows through the space between the separating jacket 12 and the Guide jacket 13 emerges from the open end of the guide jacket 13 and arrives in the annular space 14 between the guide jacket 13 and the pressure jacket 1, from which it passes through the discharge pipe 9 is dissipated.
  • the result is the one indicated by the arrows Flow course for the medium guided on the jacket side.
  • 1 in the countercurrent and 2 led in direct current to the pipe-side medium.
  • the jacket-side medium is cooled and only hits the pressure jacket 1 when it has cooled down this way, additional insulation protection on the Be dispensed with inside of the pressure jacket 1.
  • a central tube 11 cylindrical chamber 16 integrated into the radial Feed channel 10 opens out.
  • the chamber 16 is opposite lying openings 17, 18 provided, one of which with the Central tube 11 and the other with the interior of the Pressure jacket 1 is connected.
  • a valve plate 19 slidably arranged by a rod 20 guided out of the heat exchanger is adjustable. In one end position, the valve plate 19 closes the the central tube 11 leading opening 17 and in the other End position leading into the interior of the pressure jacket 1 Opening 18. In between, any intermediate position is possible.
  • In the open position (closed line in Fig. 3) is the through the feed pipe 8 entering medium flow directly and discharged uncooled via the discharge pipe 9 without he comes into contact with the tubes 2.
