Definitions

  • the invention relates to a heat exchanger with the features of The preamble of claim 1.
  • Such a heat exchanger is known from DE-A-3 147 512.
  • This heat exchanger contains U-shaped tubes and a central tube inside the bundle of U-shaped tubes, a separating jacket between the tubes and a guide jacket outside the tube bundle. In this way it is achieved that the medium to be cooled, guided on the jacket side is passed through the U-tube heat exchanger in such a way that the medium only comes into contact with the pressure jacket when cooled.
  • Several groups of U-tubes are provided, the legs of the U-tubes being arranged on concentric circles and being strictly assigned to each other.
  • the innermost pipe circle is assigned to the outermost pipe circle, the second innermost to the second outer, and so on.
  • a single group of U-tubes is used according to the invention.
  • the known heat exchanger is not provided with an adjustable bypass. It is therefore not possible to influence the temperature to which the medium to be cooled and guided on the jacket side is to be lowered.
  • GB-A-2 134 240 is a heat exchanger with U-tubes known, which are flowed through by the hot gas to be cooled.
  • the entry legs of the U-tubes open into one Gas inlet chamber, and the outlet legs open into one Gas outlet chamber that encloses the gas inlet chamber.
  • the gas inlet chamber is connected to the gas outlet chamber via a connected by a slide closable opening. Depending on the position of the slide, the gas entering the U-tubes or fed directly to the gas outlet chamber.
  • the well-known U-tube heat exchanger is not with a central tube, one Separating jacket and a guide jacket provided.
  • 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 for 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 provided.
  • a heat exchange medium e.g. B. steam provided.
  • Inside the entry chamber 4 an outlet chamber 6 is arranged which is connected to the tube sheet 3 connected and sealed off from the inlet chamber 4.
  • the outlet chamber 6 is provided with an outlet nozzle 7, 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.
  • there 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.
