Definitions

  • the invention relates to a method and a device for cooling a container filled with liquid.
  • the object of the present invention is therefore to provide a fast-acting cooling system for cooling containers filled with liquid, which also enables structurally simple and inexpensive solutions.
  • a jet of a liquid cryogenic medium is injected into the liquid to be cooled and the heated, gaseous cryogenic medium then emerging from the liquid to be cooled is discharged from the container.
  • a liquid cryogenic medium e.g. Liquid nitrogen or liquid air
  • a circulation effect and thus a good cold distribution is achieved by injecting the cryogenic medium.
  • Suitable injection pressures are between 1 and 18 bar.
  • no additional external energy supply with e.g. Electricity is more necessary because the process can be operated with the pressure with which the cryomedia is usually provided anyway.
  • the jet of the injected, liquid cryogenic medium is passed shortly after entering the liquid to be cooled through a Venturi nozzle, that is to say a gradually narrowing and expanding tube.
  • a Venturi nozzle that is to say a gradually narrowing and expanding tube.
  • an inert medium is used as the cryogenic medium to be injected.
  • Suitable media are in particular nitrogen, carbon dioxide and noble gases, in particular argon.
  • the method according to the invention is advantageously carried out in a controlled manner in such a way that the temperature of the liquid to be cooled is continuously measured and the injection of the cryogenic medium is started when the liquid temperature exceeds a specified first value, the injection then until a specified second lower temperature value is maintained.
  • a specified first value a specified first value
  • a specified second lower temperature value a specified second lower temperature value
  • a device for carrying out the method according to the invention is characterized in that an inlet nozzle and a Venturi nozzle are arranged such that their two longitudinal axes lie on a straight line, the outlet end of the inlet nozzle being at most a short distance from the inlet end of the Venturi nozzle and the diameter the Venturi nozzle at the narrowest point is slightly larger than that of the inlet nozzle.
  • the inlet nozzle is designed as a double-walled, vacuum-insulated tube. This prevents the liquid to be cooled from freezing at the inlet nozzle.
  • FIG. 1 shows a container 1 in which there is a liquid with the liquid surface 2.
  • an injection device 3 is attached to a side wall of the container, which consists of an inlet nozzle 4 penetrating the container wall and a Venturi nozzle 5 connected to it.
  • an opening 6 is provided in the upper region of the container.
  • the arrows 7 indicate a circulation movement which the liquid in the container executes while the cryogenic medium is being injected by the injector.
  • FIG. 2 shows an injection device 3 according to the invention in detail.
  • a double-walled tubular inlet nozzle which is under vacuum, that is to say insulating between the inside and outside, is fixed to a holding frame (9) with a tapering and widening again Tube, a so-called Venturi nozzle connected, the axes of both nozzles lie on a straight line.
  • the narrowest diameter of the Venturi nozzle 5 is approximately 1.5 to 4 times larger than the constant diameter of the inlet nozzle, the diameter of the Venturi nozzle approximately doubling towards both ends.
  • the change in diameter of the Venturi nozzle is smaller towards the end pointing away from the inlet nozzle than at the pointing end.
  • a liquid cryogenic medium e.g. Liquid nitrogen
  • a liquid cryogenic medium e.g. Liquid nitrogen
  • introduced through the inlet nozzle 4 into the liquid in container 1 for example at a pressure of about 4 bar, so that liquid is sucked into the space between the inlet nozzle 4 and the Venturi nozzle 5 by the cryomedium jet entering through the inlet nozzle, drawn into the Venturi nozzle and to the outlet of the Venturi nozzle accelerated there.
  • the intimate mixing of the cryogenic medium and the liquid to be cooled caused by this process results in a very effective heat exchange between the two media, as a result of which the liquid is cooled and the cryogenic medium is evaporated.
  • the gaseous cryogenic medium rises in the liquid and collects above the liquid surface 2.
  • the space above the liquid is thereby rendered inert in the case of inert cryogenic media.
  • the excess gas escapes from the opening 6 of the container
  • the compatibility of the cryogenic medium used with the liquid to be cooled is of fundamental importance when using the method. This requirement must be checked by criteria such as mutual solubility, mutual reactivity, etc. In many cases, however, a variety of cryomedia can be used.
  • the cooling method according to the invention provides an efficient cooling method with moderate effort.
