Bottom thermal insulation layer 5 is arranged between protective layer base plate 32 and secondary container floor 22, and the cold for preventing cryogenic media is transmitted from the secondary bottom of container protective layer 3.Bottom thermal insulation layer 5 is stacked by multiple layer heat insulation structure and is formed, the insulation requirements of tank bottom can be met, no matter storage tank is in nominal situation or reveals accident conditions, bottom thermal insulation layer 5 has played the cold insulation performance of maximum so that the heat that oozes that storage tank is produced under accident conditions from tank bottom is substantially reduced.Simultaneously; according to the structure design; so that all bottom cold insulation materials had completed construction before the water pressure test of secondary container protective layer 3; after the water pressure test is carried out to secondary container protective layer 3 according to code requirement; the construction for carrying out bottom cold insulation material is no longer needed, the construction period of storage tank can be shortened.
Fig. 3 illustrates the one of bottom thermal insulation layer 5 preferably embodiment, and in the embodiment, the structure of bottom thermal insulation layer 5 is from top to bottom respectively top concrete leveling layer 51, heat-insulation layer 52, foam glass brick layer 53, bottom concrete leveling layer 54.
Top concrete leveling layer 51 supports time protective layer base plate 32 of container protective layer 3, and bottom concrete leveling layer 54 is arranged on the secondary container floor 22 of time container 2.
Heat-insulation layer 52 is made up of the expanded-sand concrete collar tie beam 521 of annular with the foam glass brick 522 being arranged in expanded-sand concrete collar tie beam 521.Wherein, expanded-sand concrete collar tie beam 521 is respectively positioned in the annular extent of expanded-sand concrete collar tie beam 521 positioned at the orthographic projection region of primary tank cylinder 11 and the underface of protective layer cylinder 31, primary tank cylinder 11 and protective layer cylinder 31；Correspondingly, the margin plate 121 of primary tank base plate 12 and the margin plate 321 of protective layer base plate 32 bear the larger orthographic projection region of load in the annular extent of expanded-sand concrete collar tie beam 521.
Interlayer heat insulation layer is mainly using pearlife 4 as cold insulation material; pearlife 4 is filled with interlayer between interlayer between protective layer cylinder 31 and primary tank cylinder 11, the interlayer between protective layer cylinder 31 and secondary shell 21, and the top primary tank cylinder 11 of protective layer cylinder 31 and secondary shell 21.Interlayer heat insulation layer has intercepted transmission of the cryogenic media cold along cylinder lateral wall direction in primary tank; simultaneously also protective layer cylinder 31 is played a supporting role by the pearlife 4 of the dense packing effect; the protective layer cylinder 31 of secondary container protective layer 3 is fixedly supported between primary tank 1 and secondary container 2; secondary container protective layer 3 can be fixed without the need for anchor, reduce cold pipeline.To eliminate lateral pressure of the pearlife 4 to protective layer cylinder 31, on protective layer cylinder 31 reinforcement is additionally provided with.
Refering to Fig. 4 and Fig. 5, more preferably, elastic cotton 13 is additionally provided with outside primary tank cylinder 11, can absorb the extruding force of the pearlife 4 in pre- cold events of primary tank cylinder 11.Specifically, by one layer of cotton 14 of low temperature glue bonding on primary tank cylinder 11, then elastic cotton 13 is set, the outside of elastic cotton 13 arranges cotton 14 and glass wool cloth 15.Pearlife 4 is located at outside glass wool cloth 15.
Interval d1 between primary tank cylinder 11 and protective layer cylinder 31 is not less than 1000mm, and the interval d2 between protective layer cylinder 31 and secondary shell 21 is 450mm ~ 1000mm.More preferably, the interval d3 between primary tank cylinder 11 and secondary shell 21 is not more than 2000mm.
The metal holds under the accidental conditions of formula storage tank 100 entirely, the outer cylinder radial direction of the primary tank 1 at least insulating layer thickness of 1450mm, greatly improves the heat-insulating property of storage tank, makes storage tank have relatively low evaporation rate；And when generation abnormal conditions cause primary tank 1 to be revealed; the cryogenic media of leakage is entered and stored in time container protective layer 3; the cold that still pearlife 4 with adequate thickness is intercepted in this direction between secondary container protective layer 3 and secondary container 2 is transmitted; so that storage tank is still able to keep preferable heat-insulating property in accident condition; enable cryogenic media to enter the temperature being delivered on time container 2 by the isolation of pearlife 4 after time container protective layer 3 and be not less than the minimum temperature that time material of container 2 bears; and occur without frosting icing phenomenon on secondary container 2, it is ensured that the safety of secondary container 2.
Referring again to Fig. 2, more preferably, the metal of the present invention holds formula storage tank 100 and is provided with two sets of independent construction single tracks 8 entirely, builds the radial girders lower section that single track 8 is connected to vault 23, improves storage tank and builds convenience.
According to above-mentioned introduction, the metal of the present invention holds formula storage tank and at least has advantages below entirely：
（1）The storage tank Scheme Security coefficient of the present invention is higher；
（2）The design of the present invention can completely avoid the impact in the case where storage tank primary tank occurs leakage accident operating mode to storage tank overall security；
（3）The design of the present invention takes and arranges time structure of container protective layer, instead of time container low temperature material and selects to require, reduces low-temperature steel materials'use amount；
