Definitions

  • the invention relates to a heat exchanger and a method for operating such a heat exchanger.
  • Coiled heat exchangers are e.g. used in natural gas liquefaction plants.
  • a first fluid medium is applied as a refrigerant to the shell side and evaporates by means of a falling film. This evaporation can lead to a so-called maldistribution over the tube bundle, so that some tubes receive too much refrigerant, other tubes too little.
  • the tube side i.e. the media carried in the tube bundle
  • the first medium or the refrigerant on the shell side can also be regulated in order to compensate for a maldistribution.
  • valves arranged in the jacket space or on the tube bundle, as well as moving parts inside the heat exchanger can only be implemented with comparatively great effort.
  • the present invention is therefore based on the object of specifying a heat exchanger and a corresponding method for indirect heat transfer, which enables a particularly continuous shift of the area-related task of the first medium in a radial direction of the tube bundle and so low the cost of additional instrumentation as possible.
  • the distribution arms for applying the tube bundle with the liquid phase of the first medium have at least one first container and at least one second container separate from the first container, the first container being in flow connection with the annular channel so that the liquid phase of the first medium can be introduced from the annular channel into the at least one first container and can be distributed from there via outlet openings of the first container to a first region of the tube bundle, and the at least one second container is in flow connection with the collecting container, so that the liquid phase of the first medium can be introduced from the collecting container into the at least one second container and can be distributed from there to a second region of the tube bundle via outlet openings of the second container.
  • the distribution arms can each be designed in the shape of a sector of a circle. Furthermore, between two adjacent distribution arms in the circumferential direction of the jacket or the core tube can be separated by a gap through which the tubes of the tube bundle can be passed (e.g. towards the connection pieces provided on the jacket).
  • the heat exchanger has at least one first controllable valve, via which the ring channel can be charged with the first medium, and / or that the heat exchanger has at least one second controllable valve via which the collecting container of the core tube with the first medium can be loaded.
  • the ring channel is in flow connection with a first inlet arranged on the jacket, so that the first medium can be introduced into the ring channel via the first inlet, the first valve in particular being arranged upstream of the first inlet.
  • the collecting container of the core tube is in flow connection with a second inlet arranged on the jacket, so that the first medium can be introduced into the collecting container via the second inlet, the second valve in particular being arranged upstream of the second inlet.
  • the first container and the second container can be charged simultaneously with variable mass flows of the first medium by appropriately setting the valves.
  • the first container and the second container are arranged above the tube bundle that by setting the two valves the amount of liquid phase applied to the tube bundle per area and time in a radial direction of the Tube bundle is changeable or adjustable.
  • one embodiment of the invention provides that the arrangement of the outlet openings of the first and the second container is designed so that radially different amounts of liquid can be adjusted.
  • the second container can have outlet openings which are located further inward in the radial direction than the outlet openings of the first container.
  • the second container only have outlet openings for an inner half of the tube bundle, while the first container only has outlet openings for the outer half of the tube bundle.
  • the said amount can be changed or adjusted in the radial direction of the tube bundle so that the said amount increases monotonically towards the outside in a radial direction of the tube bundle or outwards decreases monotonously.
  • one embodiment of the invention provides that the at least one first container is formed by a first distribution arm of the liquid distributor, and that the at least one second container is formed by a second distribution arm of the liquid distributor.
  • the at least one first container is formed by a first area of a distribution arm
  • the at least one second container is formed by a second area of the distribution arm that is separate from the first area
  • the two regions run next to one another in the radial direction along which the distributor arm extends.
  • the two areas are fluidically separated from one another by a partition wall of the distributor arm that extends in the radial direction.
  • the two areas are opposite one another in the radial direction along which the distributor arm extends.
  • it can furthermore be provided according to one embodiment that the two areas are separated from one another by a partition wall extending in a circumferential direction of the core tube.
  • Another aspect of the present invention relates to a method for performing an indirect heat transfer between at least a first fluid medium and a second fluid medium using a heat exchanger according to the invention, wherein the second medium is introduced into the tube bundle, and wherein a first mass flow of the first medium over the ring channel is introduced into the at least one first container, and wherein (in particular at the same time) a second mass flow of the first medium is introduced into the at least one second container via the collecting container, the two mass flows being set (e.g. using the said valves), in order to change the amount of the liquid phase of the first medium applied to the tube bundle per area and time via the outlet openings of the at least one first container and the outlet openings of the at least one second container in the radial direction of the tube bundle put.
