Definitions

  • the invention relates to a steam-heated Heat exchanger, especially for the condensate side Regulation of heat transfer, with a one steam-heated heating system, by one secondary Heating medium flows through the housing, the upstream lying end to a return and downstream End of a flow for the secondary heating medium is connectable, and with heating steam in parallel and in Flow through countercurrent to the secondary heating medium Heating pipes connected to one at the upstream end Steam flow and at the downstream end to one Condensate return are connected, the housing from a series of parallel from the secondary heating medium flowed through jacket tubes, in each of which one of the Heating pipes is arranged, the flow side through a Jacket pipes common secondary flow line for the secondary heating medium and its wall through are led outside to the common steam flow.
  • the jacket pipes have a first Embodiment radially from its end protruding pipe socket through which the secondary Heating medium can flow into or out of the jacket tube.
  • the front sides of the casing pipes are on the flow side fluid-tight against the steam supply line sealed.
  • the Pipe socket expanded to connecting flanges, which at mutually coupled jacket tubes one with these form an integral secondary flow line.
  • the Flanges are again at a distance from the end of the Jacket pipes arranged.
  • the jacket pipes are on the front also fluid-tight in this embodiment sealed and the outflow of the secondary heating medium takes place in the radial direction.
  • a cooling of the primary Heating medium through the secondary heating medium takes place only if the primary heating medium in the heating pipe is at a distance areas from the end of the casing tube reached be washed by the secondary heating medium.
  • the heating pipes are all in one housing arranged and with their ends on two tube plates connected, of which the flow tube in the upper housing part arranged laterally in the housing wall is, while the condensate-side tube plate is the housing closes at the bottom and from a condensate collector separates.
  • the heating pipes are helically coiled, the slope of the turns from top to bottom so that the heat-exchanging surface towards Steam entry to the condensate outlet increases accordingly.
  • Such heat exchangers have become common in practice proven; the heat exchanger is easy to control and there are none at all steam pressures Sounds. However, the manufacture of one Heat exchanger very complex and expensive.
  • the advantage achieved by the invention initially exists in that the heating pipes are led through the flow line are because it ensures that the heating pipes on Steam enters through the jacket pipes and the Secondary heating medium flowing through the flow line very much to be cooled well and heat pockets from the current of the secondary heating medium is not detected and flushed through, cannot arise. This ensures that in Heat exchanger no bubbling, crackling or cracking noises can result from overheating on the secondary side.
  • the heating pipes in the area the mouth of the casing tube in the secondary Flow line and within the secondary flow line themselves have the smallest possible heat exchange surface, in particular are smooth-walled. You therefore give in this Area less heat and this heat can be from which the Secondary heating medium flowing through the flow line can be easily removed.
  • the narrowed mouth area of the casing tube from a short axial connecting piece formed by the casing tube merges with an outwardly convex shell.
  • the arrangement be such that parallel to the secondary flow line on their of the Jacket side facing away from a steam flow line to which the runs across the secondary Flow pipe connected through heating pipes connected are.
  • the heat exchanging surface of the in the Flow pipe trending heating pipe sections is then optimally small and the heat given off to the secondary Heating medium in the flow pipe correspondingly low.
  • the structure of the invention Heat exchanger has the further advantage that the secondary Flow and return line just like that Steam supply line and the condensate manifold either with one of their two or with theirs both ends of the line to the flow and return for the secondary heating medium or to the common steam flow and the common condensate return can be connected.
  • the one with the secondary supply and return lines, the Steam supply line and the condensate manifold prefabricated and pre-assembled heat exchangers very versatile connection options to the primary-side energy supply system and that secondary-side energy consumer system.
  • FIG 1 shows a heat exchanger according to the invention in Longitudinal section, Figure 2 in plan view.
  • each casing tube 1 is at the upstream end 1 ′′ a return, not shown, and downstream not lying end 1 'to yourself shown advance of the secondary Energy consumer system for the secondary heating medium in way to be described further below connected.
  • Heating pipe 2 for passing the heating steam or Condensate, with all heating pipes 2 from heating steam in parallel and flows in countercurrent to the secondary heating medium will.
  • the heating pipes 2 are at the upstream end 2 '' to a steam supply, which is itself not shown and at the downstream end 2 'to a likewise in the Drawing not shown condensate return primary power supply system connected.
  • the jacket tubes 1 are in the region of their mouth 4 in the secondary flow line 3 narrowed in cross section, wherein this narrowed mouth area in detail by one short axial connector 7 and in the transition from this connecting piece 7 to the cylindrical part of the Jacket tube 1 from an outwardly convex Shell section 8 formed.
  • This narrowing leads to an increase in the flow rate of the secondary Heating medium and thus for a good cooling of the Mouth area and the cross section of the flow line 3 penetrating sections 6 of the heating tubes 2.
  • the heating tubes 2 are then in their Mouth area of the jacket tubes 1 straight and smooth-walled section 6 helical coiled, with the outer coil diameter equal to that Inner diameter of the casing tube 1.
  • a displacer 9 which is designed in the exemplary embodiment as a tube that on return-side end 1 '' of the casing tube 1 on the end face closed, at the flow end 1 'but at the front is open and that prevents the flow of the secondary heating medium through the otherwise free interior the coiled tubing takes place.
  • they are Heating pipes 2 in the coiled area with finned pipes closely coiled tube coils.
  • the casing tubes 1 are through one side piece 10 attached to one next to each Jacket tubes 1 running common secondary Return line 11 for the secondary heating medium connected.
  • this return line 11 takes place Connection of all jacket pipes 1 to the common return of the cooled secondary heating medium from the secondary Energy consumer system, this connection optional at one of the two ends of the return line 11 or both ends of the line can be done. Also the connection of the secondary lead of the energy consumer system takes place over the secondary pipes common to all jacket pipes Flow line 3, the connection in turn to one of the both ends of this flow line 3 or on both of them Ends can be made simultaneously.
  • the condensate ends 2 'of the heating tubes 2 are each axially through the end wall of its casing tube 1 passed through and with a common Condensate manifold 12 connected in detail not shown in the figure to the Condensate return from the primary energy supply system is to be connected.
