Definitions

  • the present invention relates to tanks for cryogenic liquids, of the type comprising an internal envelope and an external envelope defining between them an intermediate volume of insulation, and a tubing for sampling cryogenic liquid in the internal envelope comprising a first part extending in the intermediate volume between a lower part of the internal envelope and an upper part of the external envelope (as known, for example, from EP-A-0 098 030), and in particular the distribution tanks, in particular of liquid nitrogen, self-pressurizable by means of said sampling tube.
  • the first part, or internal part, of the tubing comprises a section in heat exchange contact with the external envelope to at least partially vaporize the liquid sampled in the internal envelope.
  • the joining, by brazing, welding or gluing between the section and the external envelope presents a certain number of problems, in particular of deformation of the external envelope, and strike of significantly manufacturing costs.
  • the object of the present invention is to provide a reservoir for cryogenic liquid with a robust and simplified structure, with reduced manufacturing costs and allowing a wide range of choice of materials for the constituent elements according to needs and uses.
  • the first part of the tubing comprises a section maintained elastically in contact against the internal wall of the external envelope.
  • this section comprises at least one turn, elastic means cooperating with the turn to tend to cause the radial opening of the latter and therefore to keep it applied against the outer casing.
  • the sampling tube is made of light alloy, for example aluminum, care must be taken, with such materials which are good conductors of heat, to limit heat loss by direct conductivity between the internal envelope and the external envelope.
  • the first part of the sampling tube is connected to an end portion by a section made of less heat-conducting material, for example plastic material.
  • FIG. 1 shows a cryogenic tank 1 of the self-pressurizable type for the distribution of liquid nitrogen, conventionally comprising an internal envelope 2 forming a reservoir for the cryogenic liquid, and an external envelope 3 spaced from the internal envelope 2 to provide an intermediate space 4 allowing the establishment of a multilayer insulation 5 applied to the internal envelope 2, the intermediate space 4 being vacuum-pumped through a closable connection 6.
  • An absorbent product 7 is advantageously placed in the intermediate space 4 to trap any residual gases.
  • the inner 2 and outer 3 envelopes are both made of aluminum from a ferrule 11, 12 and a bottom reported by welding 13, 14, respectively.
  • the ferrule 12 of the external envelope 3 advantageously has stiffening waves 15a, 15b, 15c.
  • the reservoir comprises a neck 21, typically formed of a tubular piece of epoxy resin reinforced with glass fibers, which is glued in neck portions with reduced diameter of the envelopes 2 and 3 and secured at the end, by example by gluing, to a massive piece of aluminum 22 having an upper face support for a sealing plug and a radial passage 24 forming the downstream end of a pressurization circuit 25 comprising an external tube 26 fitted with a valve 27 extending between the passage 24 and a crossing end piece 28 of the external casing 3.
  • the pressurization circuit has an internal part 29, extending in the intermediate space 4 from the connector 28 to the lower zone of the reservoir, firstly along, at 30, a generator internal of the external envelope 3 and forming, in the vicinity of the bottom of the tank, at least two turns 31, 32 advantageously received in one of the waves (15a) of the external envelope and which are kept permanently resiliently pressed against the internal face of the external envelope as will be seen later.
  • the tubing 29 is made of a material which is good at conducting heat, in particular aluminum
  • the lower end of the part of tubing 29 is connected to a tubular section 33, made of material which is poorly conductive of heat , for example in plastic material such as an epoxy resin reinforced with glass fibers, the two ends of which are secured respectively to a nozzle 36 for connection to the tube 29 and to a nozzle 37 for connection to a curved end section 38 even connected to a nozzle 39 integral with the bottom 13 of the internal envelope 2.
  • each turn 31, 32 against the inner face of the outer casing 3 is provided by at least one tension spring 41, 42, acting between opposite portions of the turn so as to tend to cause a radial opening of the latter, the anchoring of the ends of a spring on a turn being ensured by self-locking plates 43, 44.
  • a withdrawal device 52 comprising a dip tube 53 extending to in the vicinity of the bottom of the internal envelope 2 and which gives off the radial passage 24 towards the gaseous sky of the internal envelope 2.
  • the withdrawal device 52 further comprises a valve 54 for withdrawal of the cryogenic liquid from the internal envelope 2 via the dip tube 53.
  • the outer casing 3, the inner casing 2 and the tubing part 29 and the final section 38 are made of aluminum, the tubing portions being tightly connected to the end pieces, 28, 36 and 37 by collage.
  • the tubing part 29 can be made of stainless steel, in which case the tubular section made of insulating material 33 can be omitted, the stainless steel tube being fixed to the end pieces 28 and 39 by gluing or brazing.
  • the tubing part 29 made of aluminum it is also possible to use a part of copper tubing, which also requires the use of the insulating section 33.
  • at least the internal envelope, as well as advantageously the sampling tubing can be made of stainless steel.
  • the reservoir according to the invention makes it possible to produce the internal and external envelopes as well as the sampling tubing in plastic material, for example in epoxy resin reinforced with glass fibers or in polycarbonate.
