Definitions
- the invention relates to a submarine with a tank for receiving and storage of liquid gas, especially oxygen.
- Submarines can be theirs electrical energy, especially in diving operation in whole or in part obtain from fuel cells in which, for example, oxygen and Hydrogen is catalytically oxidized to generate electrical energy.
- fuel cells in which, for example, oxygen and Hydrogen is catalytically oxidized to generate electrical energy.
- oxygen and Hydrogen is catalytically oxidized to generate electrical energy.
- a tank is required in which the oxygen is in liquid Form can be stored.
- cryogenic liquid gas especially oxygen
- Such a known tank is constructed with two shells, so it exists from a pressure-tight inner wall and a spaced one external wall solid against vacuum, between which perlite is filled in as radiation insulation.
- the space is for thermal insulation also evacuated.
- the invention is based on the object Submarine with a tank for holding and storing liquid gas, especially of liquid oxygen, to create that too the tank the submarine specific military requirements in particular enough.
- the submarine is with a Tank for holding and storing liquid gas, especially liquid gas Oxygen, equipped, the double-shell structure, the between Inner wall and outer wall with fillings for radiation insulation is provided for thermal insulation between the outer wall and inner wall is evacuated and in addition to the holding means intended for the mechanical connection of the outer wall and inner wall are, which the insulating effect of the container does not exceed the required Affect dimension beyond.
- the holding means are in the Designed only for a static load in terms of their dimensions, thus around the inner container formed by the inner wall as intended within the outer container formed by the outer wall to keep.
- the invention provides packing, which essentially Have spherical shape.
- These fillers are not only used for Radiation isolation, as is known per se, but they serve especially to absorb high shock loads without losing the To strongly influence the insulation effect (also during the shock load).
- Glass balls are particularly suitable for this because they are extremely dimensionally stable are, can be produced inexpensively and very high forces be able to record.
- the glass balls are not massive, but formed as a hollow body. This will in particular the insulation effect increases without noticeable loss of stability to have.
- Micro-glass spheres are preferred as packing elements according to the invention used as bulk material with liquid-like flow behavior, So also get into narrow spaces and thus in terms of production technology particularly favorable in the between the inner wall and outer wall formed space can be filled.
- These micro glass balls spread out liquid-like in that formed between the outer wall and the inner wall Free space, however, in the case of sudden stress, they work like they do for example by the pressure wave occurring during a detonation, similar like a solid. You thus fix the inner container with the required distance to the outer container and ensure the required Insulation even in the event of a load. Although in case of stress the thermal conductivity of the micro glass balls due to the higher surface pressure between the balls slightly larger, but this takes after the load has dropped to the same extent.
- the packing can be made of different materials Material and different sizes exist, but are preferred Micro glass balls with an average diameter of 20 to 120 ⁇ m used, and that in compressed form.
- By compressing the Filled bodies filled into the space will have a higher packing density and thus achieved a higher stability.
- the condensing can be done by means of a vibrating device known per se.
- To the These are to further reduce the thermal conductivity of the micro glass balls advantageously not designed as a solid body but as hollow spheres and have a wall thickness that, depending on the pressure requirement 0.2 and 5 microns.
- the design of the liquid oxygen tank according to the invention is, at least as far as the holding means between the inner and outer tank is relatively easy since it is essentially for recording the static loads acting between the inner wall and the outer wall is designed and trained.
- the holding means therefore only serve to the normal position of the inner tank under normal static conditions to hold to the outside tank. You don't need an elevated one (dynamic) load to be designed, which is not just constructive is advantageous, but also has advantages with regard to the insulating effect.
- the holding means can namely in the form of, for example, crosswise stretched elongated ligaments between the inner wall and outer wall be educated. Such an arrangement is particularly advantageous since then the inner tank formed by the inner wall virtually inside of the outer tank formed by the outer wall can be d. H. the holding elements are only subjected to tensile loads. This then do not need to be designed to be rigid and can have a comparatively small cross-section, so that the insulating effect comparatively between the inner and outer container through the straps little deteriorates.
- liquid gas in particular liquid oxygen is stored under pressure and refrigerated, the Submarine specific requirements regarding shock load and Storage time (for example over a week) without additional facilities can be achieved for heat dissipation.
- the tank 1 shown in the figures for the storage of liquid Oxygen on a military submarine is more appropriate (not shown) Place in the submarine, this can be inside or be outside the pressure chamber.
- the tank 1 has an inner wall 2 on, which forms a pressure-tight inner container (inner tank) in which the oxygen 3 is stored.
- 3a in the figures is the liquid oxygen and marked with 3b the gaseous fraction within the tank 1.
- the inner wall 2 is substantially cylindrical and shaped at the ends approximately hemispherical inner container, the on all sides with an essentially constant distance 4 to an outer wall 5 is arranged, which forms an outer container (outer tank) that the has the same shape as the inner tank, but is significantly larger to surround it at a distance of 4.
- the inner container formed by the inner wall 2 is via carrying straps 6 within the outer container formed by the outer wall 5 suspended.
- the carrying tapes 6 are arranged on at least six sides, in pairs and crossed around them if possible to be able to train for a long time.
- the tapes 6 are designed so that they are in the Essentially bear the static load, which is the one filled with oxygen Inner container generated in particular by its weight.
- the Bands 6 as well as the inner and outer containers are made of steel and welded to them.
- the space formed between the inner wall 2 and the outer wall 5 is with Micro glass balls 7 completely filled, moreover, in this Space have been compacted.
- the one with compacted micro glass balls 7 filled room is then evacuated, d. H. placed under vacuum in order to achieve a high insulation effect. Due to the compression and evacuation, the micro glass balls 7 are resistant to abrasion packed, so that even in normal operation no wear arises within the insulation. They take it in case of shock for example in the amount of 10 to 100 g of forces without the straps 6 being additionally noticeably loaded. The insulation effect is almost completely retained completely restored immediately after loading.
