Definitions

  • the invention relates to a heat exchanger, in particular a wound heat exchanger, and a method for distributing a liquid phase to a tube bundle of a heat exchanger
  • Such a heat exchanger is used for indirect heat exchange between at least a first medium, which is guided in a tube bundle of the heat exchanger and a second medium, which is guided in a surrounding the tube bundle shell space, which is bounded by a pressure-bearing jacket of the heat exchanger.
  • the two-phase entering refrigerant is usually separated in a pre-manifold of the heat exchanger by gravity in a gaseous phase and a liquid phase and then passed the liquid phase in a main manifold and abandoned by this (as a second medium) on the tube bundle ,
  • the liquid phase from the pre-distributor is fed into a central core tube and then directed (um) into the distribution manifolds of the main distributor. From there, the distribution takes place via the tube bundle.
  • the core tube absorbs the load of the tube bundle.
  • the central inlet into the distributor arms of the main distributor leads, in particular when starting the system, to an oversupply of the inner layers with refrigerant (or second medium), which can result in various thermo-hydraulic problems. For example, during start-up, an increased amount of gas to be flared is produced.
  • the use of the core tube as a distributor component means that the core tube and the pre-distributor are combined in terms of production technology. This does not allow independent or parallel production.
  • the present invention is therefore based on the object of providing a heat exchanger and a corresponding method for distributing a liquid phase, which reduces the problems mentioned above.
  • a heat exchanger for indirect heat exchange between a first medium and a second medium.
  • the heat exchanger has at least the following components: a core tube extended along a longitudinal axis, on which a plurality of tubes for receiving the first medium is wound, the tubes forming a tube bundle; a pre-distributor having a liquid space for receiving a liquid phase of the second medium to be distributed to the tube bundle, wherein during normal operation the pre-distributor is not filled with the liquid phase beyond the liquid space; a centrally arranged with respect to the longitudinal axis inlet for introducing the liquid phase in the Liquid space; and a main manifold having a plurality of distributor arms for distributing the liquid phase to the tube bundle.
  • the invention provides that the distributor arms are in fluid communication with the liquid space of the pre-distributor via at least one flow path extending outside the core tube, the core tube being arranged or sealed with respect to the liquid space such that the liquid phase leaves the liquid space during normal operation of the heat exchanger can not be fed via the core tube into the distributor arms of the main distributor.
  • the core tube is arranged so separated from the liquid space or fluidly separated from this, that the liquid phase (especially during normal operation) from the liquid space is fed exclusively via the flow path in the distribution arms of the main manifold or can get.
  • the term 'liquid space' designates that portion of the pre-distributor or the volume which contains the liquid phase during normal operation of the heat exchanger. That is, the liquid space is limited at the top by the level of the liquid phase.
  • the liquid space during normal operation along the longitudinal axis extends maximally to the outlet opening of the core tube, so that the liquid phase can not penetrate through the outlet opening in the core tube , Filling the pre-distributor with the liquid phase beyond the outlet opening is thus not provided for the intended operation of the heat exchanger.
  • the heat exchanger has a central inlet for introducing the liquid phase into the liquid space. That is, the pre-distributor is in particular not a ring distributor with radially arranged to the longitudinal axis inlet.
  • the free cross section for draining the liquid phase can advantageously be increased in such a way that degassing of the liquid phase is possible.
  • the behavior of the distributor can be improved in exceptional driving conditions (for example when starting up).
  • exceptional driving conditions for example when starting up.
  • an oversupply of the inner layers of the tube bundle during startup of the system can be avoided since the liquid phase can be distributed radially further outward through the flow paths outside the core tube.
  • typical thermo-hydraulic problems during startup of the system can be avoided, which reduces the amount of gas usually burned off during startup in LNG systems.
  • the distributor arms of the main distributor are not connected to the feed of the liquid phase to the core tube, it is advantageously possible to manufacture the main distributor and / or the pre-distributor separately (ie not together with the core tube).
  • the core tube has an outlet opening arranged in the predistributor at an upper end of the core tube, wherein the outlet opening is arranged in the direction of the longitudinal axis above the liquid space, so that the liquid phase does not flow from the liquid space via the core tube into the distributor arms of the Main distributor is fed.
  • the heat exchanger has a baffle plate arranged with respect to the longitudinal axis below the central inlet, wherein the outlet opening of the core tube is arranged below the baffle plate with respect to the longitudinal axis, so that the liquid phase from the central inlet can not fall directly into the outlet opening.
  • the at least one flow path is formed by a downcomer extending along the longitudinal axis, so that the liquid phase to be distributed can be fed via the downpipe from the liquid space into the distributor arms.
  • Such downpipes are also referred to as 'downcomers'.
  • each distributor arm is in fluid communication with the liquid space of the pre-distributor by means of one or more downcomers.
  • the number and dimensions (e.g., tube cross-section) of the downcomers vary with respect to the entire heat exchanger and / or relative to a distributor arm.
  • At least one of the distributor arms is formed by a lower portion of a shaft which extends from the pre-distributor along the longitudinal axis, so that the liquid phase to be distributed via the shaft from the liquid space into the respective distributor arm can be fed.
  • all distributor arms of the main distributor are formed by corresponding shafts.
  • the corresponding shaft may be extended in a radial direction between the core tube and a jacket of the heat exchanger, wherein the shaft has a maximum radial extent corresponding to at least the maximum radial extent of the respective distributor arm, with which the corresponding shaft is in fluid communication.
  • the shaft in cross-section (perpendicular to the longitudinal axis) has the same shape as the corresponding distributor arm, which forms the lower portion of the shaft.
  • the cross-section may be pie-shaped.
  • the distributor arms are in flow communication via at least one compensation line, so that the liquid level of the liquid phase located in the distributor arms can be compensated by a flow of the liquid phase via the at least one compensation line.
  • the at least two distributor arms communicate hydraulically.
  • the at least one compensation line is a ring line (in relation to the longitudinal axis) in the circumferential direction of the heat exchanger.
  • the equalization line can advantageously achieve a more uniform distribution of the liquid phase within the main distributor.
  • the distributor arms extend in a radial direction between the core tube and a jacket of the heat exchanger and in an axial direction along the longitudinal axis, wherein the distributor arms each have a roof covering the respective distributor arm in the axial direction on the side facing the predistributor closes, and wherein the respective roof in the radial direction towards the jacket, ie towards the outside, falls off.
  • the distributor arms are in flow connection with the core tube, so that the gaseous phase located in the distributor arms can be removed from the distributor arms via the core tube.
  • the core tube has an outlet opening, wherein the core tube is in flow communication with a gas space of the predistributor at the outlet opening, so that the gaseous phase located in the distributor arms can be introduced into the gas space via the core tube.
  • the gaseous phase can be withdrawn from the gas space of the pre-distributor.
  • the gas space is arranged in particular during normal operation of the heat exchanger over the liquid space of the pre-distributor.
  • the core tube terminates in the gas space, wherein in particular the outlet opening is arranged on the front side of the core tube, and wherein the core tube protrudes with the outlet opening over the liquid space of the pre-distributor, so that the liquid phase can not get out of the liquid space in the core tube.
  • a method of distributing a liquid phase to a tube bundle of a heat exchanger according to the first aspect provided the invention.
  • the first medium is passed through the tubes of the heat exchanger, wherein the liquid phase is introduced into the liquid space of the pre-distributor, and wherein the liquid phase is fed exclusively via at least one outside of the core tube flow path in the distribution arms of the main manifold and from there is placed on a tube bundle of the heat exchanger.
  • the liquid phase between the distributor arms and the liquid space of the predistributor forms a coherent liquid column.
  • the at least one flow path in particular the downpipes or the ducts, has been submerged and the liquid level is located in the liquid space of the predistributor.
  • the liquid phase forms a first liquid column in the flow path and a second liquid column in the liquid space of the predistributor, wherein the first liquid column is separated from the second liquid column by a gas volume located in the flow path.
  • the gas volume located between the first and second liquid column can in particular contain liquid droplets which rain down from the liquid space of the predistributor onto the first liquid column standing in the flow path.
  • Such operation with non-submerged flow paths has the advantage that the level of the liquid phase in the pre-distributor varies less between different operating conditions, so that the overall height of the pre-distributor can be advantageously reduced.
  • FIGS. 1 and 2 show a wound heat exchanger 1 with a tube bundle 2, which serves to receive a first medium, which is to occur in an indirect heat exchange with a guided in a surrounding the tube bundle 2 shell space 5 liquid phase F.
  • the jacket space 5 is bounded by a pressure-bearing jacket 4, which extends along a longitudinal or cylindrical axis Z, which is arranged in the ready state of the heat exchanger 1 parallel to the vertical.
  • the tube bundle 2 has a plurality of tubes 20, which are each helically wound on a core tube 3 extended along the longitudinal axis Z, which is arranged coaxially with the jacket 4 in the jacket space 5.
  • the core tube 3 takes on the load of the tube bundle 2.
  • a two-phase mixture is first passed from above into a pre-distributor 100 of the heat exchanger 1 via an inlet 104 running along the longitudinal axis Z, for example.
  • the predistributor 100 has a bottom 101 extending transversely to the longitudinal axis Z and a circumferential lateral wall 102 which extends therefrom.
  • the inlet 104 further has an operating opening of the heat exchanger 1 downwardly facing inlet opening 105, which is opposite to a baffle plate 103, the above of the bottom 101 of the pre-distributor 100 in the pre-distributor 100 is arranged.
  • the two-phase mixture can flow off the baffle plate 103 to the bottom 101 and is collected and calmed there, whereby a gaseous phase G can outgas from the two-phase mixture.
  • the liquid phase F of the two-phase mixture collects in a liquid space 110 of the pre-distributor 100, while the outgassed gaseous phase G collects in a gas space 120 of the pre-distributor 100 arranged above the liquid space 110 and can be withdrawn, for example, from the gas space 120.
  • the core tube 3 protrudes through the bottom 101 of the pre-distributor 100 into the pre-distributor 100.
  • the core tube 3 has an outlet opening 31 at the top, which is arranged below the baffle plate 103.
  • the core tube 3 protrudes into the gas space 120 of the pre-distributor via the liquid space 110 of the pre-distributor 100, so that the liquid phase F located in the liquid space 110 can not flow into the core tube 3.
  • the pre-distributor 100 is only filled with the liquid phase F to such an extent that the liquid level of the liquid phase F lies below the outlet opening 31.

  • the distributor arms 201 can each be connected to the pre-distributor 100 via a downpipe 11 or via several downpipes 11.
  • the flow cross section of the flow path 30 is increased compared to heat exchangers of the prior art with running in the core tube flow path, so that during the downflow from the pre-manifold 100 in the distributor arms 201 better degassing of the liquid phase F is enabled.
  • the distributor arms 201 are limited (in the embodiment with downpipes 11) at the top (in the operational configuration of the heat exchanger 1) by a respective roof 203, which decreases in particular in the radial direction R from the central core tube 3 to the jacket 4 out.
