Definitions

  • the present invention relates to a method and a device for storing cryogenic fluids.
  • the invention more particularly relates to a cryogenic fluid storage device comprising a reservoir comprising an inner casing for containing cryogenic liquid, an outer casing and a vacuum insulation space between the inner and outer casings, a system of dispensing fluid from the inner casing to a working volume of a pumping member.
  • cryogenic pump In order to pump fluid contained in a cryogenic tank, the ideal location of the cryogenic pump is within the same liquid within the internal storage casing. Indeed, in these conditions the pump always remains cold and can be started at any time instantly without requiring prior cooling to bring it to the working temperature. In addition, in this configuration, the cryogenic liquid is admitted into the pump in the best possible conditions.
  • the document U5884488 discloses a pumping system for cryogenic tank with double jacket in which the pump is partially housed in the inter-wall space.
  • the pumping chamber is connected to the liquid part of the tank via a suction pipe comprising a non-return valve.
  • the valve is also connected to the gaseous part of the reservoir via a second gaseous conduit connected to the non-return valve.
  • auxiliary tank supplied with liquid from the tank and arranged at the foot of the latter.
  • the auxiliary tank consists of a small vacuum insulated capacity comprising the cold head forming a suction chamber and containing the cylinder of the pump.
  • the supply valves are open to feed the pump with the tank liquid in order to put the pump to temperature.
  • the cooling of the pump is thus not instantaneous and causes a significant refrigeration loss, the coolant and is vaporized and returned to the gas phase tank is heated and returned to the liquid phase in the tank. After cooling, the pump can be started. After use, stopping the pump isolates the tank capacity.
  • An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
  • cryogenic storage device which moreover complies with the generic definition given in the preamble above, is essentially characterized in that the working volume of the pumping member is located at less partially within the vacuum isolation space and in that the fluid distribution system comprises one or pipes able to put in permanent fluidic communication the fluid contained in the inner envelope and the working volume.
  • An object of the present invention is to provide a method and a device for storing and dispensing cryogenic fluids from a reservoir overcoming all or some of the above disadvantages.
  • the device for storing cryogenic fluids illustrated comprises a reservoir 100, for example of the vertical type, conventionally comprising an inner envelope 2 intended to contain cryogenic liquid and an outer envelope 22 separated from the inner envelope 2 by an isolation space 15 under vacuum.
  • the vacuum insulation space 15 forms a lower capacity which extends downwards.
  • a working volume 1 for a cryogenic pump (or thimble) is housed within the isolated volume under vacuum (e.g. in the lower capacity).
  • the working volume 1 for the pump has for example a generally oblong shape (cylindrical for example) and is preferably inclined at an angle A by relative to the vertical axis of the tank 100.
  • the tilt angle A of the working volume 1 may be between about 25 and 70 degrees.
  • the working volume 1 is supplied with fluid from the reservoir 100 by a thermosiphon system comprising a first pipe or inlet pipe 3 connected to the lower part of the inner casing and to the lower part of the working volume 1.
  • the thermosyphon comprises a second return line 4 connected on the one hand to the inside of the tank (above its base) and, on the other hand, to a median or upper part of the working volume 1.
  • a liquid level 5 is established naturally and permanently within the volume 1 of work filling the latter at least in part.
  • the cylinder 6 of the cryogenic pump is constantly immersed and at a suitable temperature to start immediately.
  • Valves 7, 8 respectively arranged at the junctions between the inlet pipes 3 and return 4 on the one hand and the working volume 1 on the other hand are provided for the appropriate fluidic isolation of the working volume vis-a-vis with respect to the tank 100 so as to allow the assembly / disassembly of the pump and its removal (the pump is preferably removably arranged in the working volume).
  • Each valve 7, 8 may be associated with a respective operating member (or common).
  • the actuators of the valves 7, 8 have respective portions 13, 14 located outside the vacuum insulation space 15, the outer portions 13, 14 being protected by caps 11, 12 respective removable masks.
  • the sealing of the valve system may comprise a packing system 9, 10 disposed at each junction between the vacuum insulation volume 15 and the outer portions 13, 14 of the actuating members of the valves 7, 8.
  • the invention allows a better operation of a pumping system for cryogenic tank (and in particular a quick start of the pump).
  • the invention which limits the refrigeration losses also allows easy maintenance of the storage assembly.
  • the invention also makes it possible to integrate an alternative pump operating at pressures of, for example, between 30 and 600 bar in order to obtain an assembly acting as a high-pressure evaporator.
