Definitions

  • the present invention relates to the distribution of gases. It relates more precisely to a device for delivering and storing cryogenic liquid, of the type comprising a double-jacketed container wedged in a parallelepipedic protective frame which completely surrounds the container.
  • cryogenic liquids in particular liquefied air gases
  • evaporators large capacity storage containers or "evaporators”.
  • LGC Liquid Gas Cylinder
  • LGCs are small, generally cylindrical transportable evaporators fitted with an atmospheric vaporizer-heater. Their useful capacity is limited to 165 liters and their full weight is between 300 and 350 kg depending on the gas they contain. Their relatively small size makes it possible to handle them by hand and to integrate them easily into the traditional distribution circuits of compressed gas cylinders, so that they are exchanged "full against vacuum” like bottles.
  • LGCs are poorly integrated into the distribution circuits of bottles in baskets, because of the empty spaces between LGCs and baskets, difficulties of wedging which result therefrom, and as a result of the risk of damage to LGCs.
  • the object of the invention is to provide a gas delivery assembly allowing integrated delivery of cryogenic liquids by limiting gas losses for the user, without any problem of re-cooling or of fragility to shocks.
  • the invention relates to a device of the aforementioned type, characterized in that the frame is provided with handling means, the container being equipped with an atmospheric vaporizer-heater arranged inside the frame and comprising vertical fin tubes arranged in corners of the frame.
  • the container is equipped with operating accessories such as a filling line provided with a valve, safety and control devices and a rapid pressurization circuit, all these accessories being arranged at the inside the frame.
  • operating accessories such as a filling line provided with a valve, safety and control devices and a rapid pressurization circuit, all these accessories being arranged at the inside the frame.
  • GB-A-544 342 describes a delivery and storage device of the type indicated at the start, intended in particular to equip a rail car iron.
  • FR-A-2 130 315 shows another delivery and storage device for cryogenic liquid, equipped with a helical vaporizer-heater.
  • the device 1 shown in Figures 1 and 2 is intended for the storage of a cryogenic liquid, in particular an air gas (oxygen, nitrogen, argon) in liquefied form. It essentially comprises an external frame 2 and a double-envelope container 3 provided with the various accessories necessary for its operation. The container 3 and its accessories are entirely disposed inside the frame 2, which protects them from all sides.
  • a cryogenic liquid in particular an air gas (oxygen, nitrogen, argon) in liquefied form.
  • air gas oxygen, nitrogen, argon
  • the frame 2 has a generally parallelepiped shape and is made up of metal beams fixed to each other so as to define a base 4 which has two horizontal slots 5 for the passage of a forklift fork, a vertical upright 6 in each corner , an upper spider 7 at the center of which is fixed a lifting ring 8, and intermediate crosspieces 9 serving to stiffen the assembly and to protect the container 3 and its accessories.
  • the container 3 is a conventional double envelope container for cryogenic liquid. It is wedged in frame 2 by pressing on a centering seat 10 secured to the base 4 and clamping by appropriate means (not shown) comprising for example straps and tensioning devices.
  • Frame 2 has, seen in plan, a rectangular shape.
  • the vaporizer 20 comprises four vertical tubes 22 with longitudinal fins 23, namely a pair of tubes connected by their lower ends in each of two adjacent angles of the frame. The top of one of these tubes is connected to the pipe 19, and that of the associated tube is connected to the top of the first tube of the other pair, the last tube being connected by its top to the end piece 21.
  • frame 2 All the elements contained in frame 2 are suitably fixed to the latter by suitable means, not shown.
  • the device 1 is intended to be integrated in a mixed gas delivery system in gaseous and liquid forms which also comprises a set of basket baskets 24 all identical. More precisely, the plan dimensions of the frame are an exact multiple of those of a bottle basket.
  • each bottle basket is parallelepiped and intended to contain eight bottles 25 of gas under pressure, and its base has the length a and the width b ; the base of frame 2 is small dimension a and for large dimension 2 b , so that the frame 2 has exactly the same dimensions as two juxtaposed wine baskets.
  • This makes it possible to fill the platform of a delivery truck 26 with both bottle baskets and devices 1 (three in number in the example shown) without loss of space and without stalling problem.
  • the container 3 can have a large capacity, for example 450 liters.
  • this large capacity makes it possible on the one hand to reduce the gas losses linked to the opening of the pressure limiting valves, and on the other hand to provide a non-withdrawable liquid residue, for example of the order 5%, or 5 to 10%, of the capacity of the container, and as a result of filling "cold".
  • the dip tube 3A serving for the withdrawal of liquid descends, through the neck 13, only to level N, and the tube 3B connected to the coil 16 for setting rapid pressure rises in container 3 to a point slightly above level N.
  • the device 1 therefore lends itself perfectly well to a "full against vacuum” exchange, in the same way as the bottles contained in the baskets 24.
  • a 450 liter container 3 propped with its accessories in a frame having dimensions a and 2 b close to 1 m and a height of around 2 m, provides a storage device 1 a weight, when full, of the order of 1000 kg. Thanks to a non-bunkable reserve of 22.5 liters, the container can be kept cold for around 70 hours after the racking has stopped.
  • Another advantage of device 1 compared to LGCs lies in the fact that, since all the accessories are protected by frame 2, they are much easier and economical to produce. More specifically, the frame alone provides protection for the container and its accessories against impacts, without involving them in the mechanical strength of the assembly. Thus, the frame is designed to deform without the container being reached and, if its deformation is too great, it can be changed easily, because it is removable and interchangeable. Therefore, it has the additional advantage of being able to be adapted to the dimensions of the bottle baskets of each user.
  • the vaporizer-heater 20 may include tubes in each corner of the frame.
