Definitions
- the invention relates to thermal insulation for one Ball tank, especially for holding cryogenic Liquids such as liquefied petroleum gas from one Insulating coating from on the surface of the spherical tank attached panels, the ball tank roughly in its Equatorial plane has an annular skirt, on the Inside fittings are attached.
- the invention relates primarily to spherical tanks, such as them on board ships for the transport of cryogenic goods Liquids such as liquefied petroleum gas are used will.
- This spherical tank is supported on an annular, approximately in the equatorial plane with the Ball tank welded tank farm, which also as Apron is called.
- An isolation technology The problem here is the transition from the insulating covering upper hemisphere to lower hemisphere. To in this The insulating covering is to avoid cold spots the upper hemisphere into the area of the apron continued.
- Fittings made of insulating material attached. This Fittings ensure an insulating transition to the Insulation covering the lower hemisphere.
- slats are with blocks on their upper edge glued, which in turn firmly attached to the fittings are connected. On the opposite lower edge the slats are glued to further blocks that in turn firmly with the upper edge of the insulating covering the lower hemisphere.
- the slats themselves are made of flexible insulating material. Several these slats are an insulation package stacked on top of each other.
- the invention addresses the problem that Relative displacement between the fittings and the through the upper edge of the insulating covering of the lower hemisphere to allow structurally simpler means.
- Thermal insulation characterized in that between the Insulating coating of a lower hemisphere of the spherical tank and a gap is arranged in the fittings, which in Radial direction of the spherical tank at least over a part its length outwards compared to the horizontal increases.
- the invention is based on the finding that cold Gas goes down while warm gas goes up increases. Between the fittings and the top of the Insulation covering the lower hemisphere is now a gap increasing at least partially towards the outside arranged. This prevents the on the Cold gas present on the inside of the insulating covering can flow outside. A heat transfer by convection is thus due to the outwardly increasing gap avoided surprisingly simple way.
- After a preferred embodiment of the invention increases the Gap outwards over its entire length. The too entry of the gap facing a tank wall thus deeper than the outward exit the same.
- the gap can be either continuous or gradually increasing as well as V-shaped or U-shaped be trained.
- Ball tanks are primarily used to transport cryogenic goods Liquids such as LPG on board Ships. They usually have a diameter of about 40 m. When empty, this corresponds to Internal temperature of the tanks to the ambient temperature or a significantly higher temperature than theirs Operating temperatur.
- the tanks are filled with liquefied gas filled, the internal temperature is at the boiling point of the respective liquid gas in the prevailing in the spherical tank Pressure (operating temperature).
- the Ball tank In the unfilled, warm (assembly) state, the Ball tank roughly a spherical shape. In the cold, filled (operating) state, the ball tank pulls easily together. Judging from a usual one Ball tank diameter of 40 m, so the migrates Tank wall 10 in the area of the equatorial plane by about 90 mm in the operating state compared to the assembled state Inside.
- the ball tank is supported to a certain extent Height range through a circular tank farm. This is commonly called apron 11.
- the Apron 11 is in the area of the equatorial plane with the Tank wall 10 firmly connected.
- the ball tank For absorbing cryogenic liquids, for example of liquid gas, the ball tank must of course have very good thermal insulation. Both one are lower and an upper hemisphere of the spherical tank for this purpose with an insulating covering 12 or 13 Mistake.
- the insulating coverings 12, 13 are made prefabricated panels 14 assembled. The panels 14 are in rows on top of each other and staggered in rows arranged to each other. The formed from the panels 14 Insulating coverings 12, 13 are known per se and not Subject of the invention.
- a special The isolation problem is the transition from that Isolierbelag the upper hemisphere to Isolierbelag 13 der lower hemisphere in the area of the apron 11.
- the Insulating covering 12 of the upper hemisphere is for this purpose led into the area of the apron 11.
- On the Moldings 15 are attached to the inside of the apron 11.
- On the opposite to the fittings 15 The bottom of the apron 11 is the lowest Row of panels 14 of the insulating covering 12 of the upper Hemisphere. As a result, a heat flow through the Apron 11 reduced to the desired size.
- the panels 14 are fixed on the tank wall 10 appropriate. Because of the above temperature-related displacement of the tank wall 10 the upper edge of the insulating covering 13 also migrates lower hemisphere about 90 mm inwards (starting from a tank diameter of 40 m). The apron 11 and with but the fittings 15 remain in theirs Assembly condition. This relative shift between the Fittings 15 and the upper edge of the insulating covering 13 the lower hemisphere must go through thermal insulation be balanced. At the same time, no one is allowed here Insulation weak point.
- Block 16 is on the bottom the moldings 15 a block 16 attached.
- Block 16 is particularly firmly bonded to the fittings 15 connected.
- On the top row of panels 14 of the Insulating covering 13 of the lower hemisphere is a block 17 arranged and, like the panels 14, with a Fastening bolt 18 attached to the ball tank.
- On the Block 17 is a block 20 attached.
- a seal 24 is arranged within the gap 21.
- This seal 24 is made of a material that is (cryo-) flexible even under the operating temperatures prevailing on the ball tank.
- the seal 24 is made from a ployimide foam that has a low density (about 10 kg / m 3 ). This material has a high flow resistance and remains elastic even at temperatures down to -196 ° C. At these low temperatures, polyimide foam is also sufficiently permanently elastic.
- An alternative material would be mineral wool.
- the seal 24 is within a groove 25 in the block 20th arranged.
- the seal 24 elastically deformed and presses against the lower wall of block 16.
- the undeformed state is in FIG. 2 indicated by dashed lines.
- the seal 24 slides during the temperature shifts on the lower wall of the Blocks 16.
- the lower wall of block 16 with a film with good sliding properties, for example, an aluminum composite film, laminated.
- the size of the gap 21 is chosen so that it is under remains open in all operating states. This will avoided that tensions between the fittings 15 or blocks 16 and blocks 17 and 20 respectively will. Only the seal 24 slides on the block 16.
- 1 and 2 is a cover 26 recognizable.
- This cover is on the one hand Fittings 15, namely on the lower wall, and on the other hand on the insulating covering 13 of the lower hemisphere, namely attached to block 17.
- On the lower wall the fittings 15 and the outer wall of the block 17 for this purpose plywood panels 27, 28 glued on.
- On these plywood panels 27, 28 are in the drawing Unscrewed sheet metal angle screwed into the the cover 26 on its lower or upper edge is glued.
- the cover 26 itself is from individual, in the circumferential direction of the spherical tank successive cover slats 31 are formed.
- the cover slats 31 are also through one another the elastic sealant glued together.
- the elastic sealing compound takes up compressions or Strains within cover 26 as a result of Temperature shift on.
- the cover slats 31 are formed in two layers, namely made of a flexible polystyrene, which is covered with a thin aluminum sheet 32 is laminated.
- the Aluminum sheet 32 preferably has a thickness of 0.3 mm on.
- the aluminum sheet 32 is used in the present case on the one hand as a vapor barrier and on the other hand as mechanical protection.
- the cover plate 31 from the flexible polystyrene in turn has certain thermal insulation properties.
- Main task of the cover 26 is the following:
- the Ball tank namely its tank wall 10
- purge gas Inert gas
- the purging gas is activated by an inlet in a space between the insulating coverings 12, 13 and the tank wall 10 is pumped in and passes through one Leaves again, in the area of which there are gas detectors are located. 1 and 2.
- Such a space is recognizable as an annular gap 33.
- the ring gap 33 prevails an internal pressure increased against the ambient pressure, the through the gap 21 between block 16 and block 20 could escape. This would also be the case with the seal 24 can hardly be prevented.
- the increasing gap 21 and the seal 24 are taken individually good means to the exit of cold gas due to convection from the annular gap 33 in to prevent the annulus 34.
- the best effect will be by a combination of increasing gap 21 and the Seal 24 achieved. For example, have experiments result in the following:
