Embodiment
On Fig. 1, can partly see sealing heat-insulated container 1, described sealing heat-insulated container forms by being fixed on the corresponding wall 4 of bearing structure and the container wall 2 and 3 on 5 internal surface.Bearing structure is for example the inner housing of double hull boat or the building that is positioned at ground.For holding cold product as LNG, container wall comprises at least one sealing barrier 6 and at least one heat shield 7.For considering of safety, can be at bearing structure and be called as in this case the secondary sealing barrier not showing is set between the sealing barrier 6 of primary seal barrier.
Container 1 can be implemented according to known different geometries, for example prismatic geometrical shape in ship hull or on the ground cylindrical body geometrical shape or other.In addition, many methods can be used for implementing heat shield and sealing barrier, for example, utilize prefabricated elements to implement heat shield and sealing barrier.
In the diapire 3 of container, illustrate and extend shape rigid member, described elongation shape rigid member forms leg 10, and it extends through heat shield 7 and sealing barrier 6, an end is supported on the diapire 5 of bearing structure and the other end protrudes out in container away from sealing barrier 6.Leg 10 can be for example for supporting the equipment 9 that should be immersed in container.For example, for supporting drainage pump, leg can be disposed in the bottom of the container pumping bar not showing.Although leg is shown here on the diapire of container, similar rigid member can be disposed in other position in container in an identical manner, for example interval or the supporting member for arbitrary object is kept away from container wall.
For implementing sealing barrier 6, can use sheetmetal, sheetmetal has ripple, and ripple forms elastic region, to absorb thermal shrinkage and static pressure and kinetic pressure.The sealing barrier that this class is made by ripple sheet material or concave-convex grain sheet material was particularly described in document FR-A-1379651, FR-A-1376525, FR-A-2781557 and FR-A-2861060.Now with reference to Fig. 2 and Fig. 3, this possibility is launched to describe.
With reference to Fig. 3, sealing barrier 6 is comprised of a plurality of ripple sealing plates 11, described a plurality of ripple sealing plates so-called internal surface for contacting with fluid-phase.Sealing plate 11 be thin metal as corrosion resistant plate or aluminium sheet element processed, these sealing plates are welding together at 12 places, overlapping edges region between them.Welding is the welding of lap welding type, and its method was for example described in detail in patent documentation FR-A-1387955.Sealing plate 11 can with regard to sealing plate design in many ways with regard to shape and size sizes, welding region can be located in many ways.
Sealing plate 11 comprises that First Series is called ripple 15 and second series longitudinally and is called horizontal ripple 16 within it on surface, and the direction separately of described First Series ripple and second series ripple is vertical.The height of First Series ripple 15 is lower than the height of second series ripple 16.Therefore, ripple 15 is discontinuous at the infall 18 of itself and continuous ripple 16.Longitudinal ripple 15 and transverse wave 16 protrude to the inside of container 1.
Leg 10 has the revolution shape in rounded cross section here, and with part under truncated cone shape 13, under this truncated cone shape, partly at less 17 places, end of its diameter, being connected to cylindrical upper section divides 14.The bottom support that under truncated cone shape, the diameter of part 13 is larger is on the wall 5 of bearing structure.Under truncated cone shape, part 13 extends beyond sealing barrier 6 positions through the thickness of container wall.Cylindrical upper section divides 14 by circular plate 19, to be sealed shut, and circular plate 19 can for example be welded on cylindrical upper section and divide on 14 the inward flange not showing.
For allowing leg 10 to pass through, the ripple sealing plate 11 that forms sealing barrier 6 is cut to define the square fenestra 25 around leg 10.For realize the continuity of sealing barrier 6 at fenestra 25 places, between leg 10 and sealing plate 11, implement the sealing assembling of connector element.Because the diameter of leg 10 is greater than the interval between First Series ripple 15, therefore some crossing longitudinal ripples of, its directrix A that represent with numeral 20 and leg 10 are interrupted at fenestra 25 places.Similarly, because the diameter of leg 10 is greater than the interval between second series ripple 16, therefore with some transverse waves shown in numeral 21, that its directrix B and leg 10 are crossing, at the fenestra place around leg, be interrupted.
In addition, as visible on Fig. 3, in fact, the size of fenestra 25 is greater than the diameter of leg 10, so that being in place of connector element is relatively easy.Therefore, the fenestra 25 of arranging in corrugated sheet can interrupt such ripple in a similar manner: ripple in fact not with the crossing directrix of leg very near leg, to allow, between these ripples and leg, connector element is installed.
The center C of leg 10 is positioned between the directrix A of ripple 20 of interruption and between the directrix B of the ripple 21 interrupting, more precisely the central authorities of these directrixes on Fig. 3.Because this location makes, the each string of a musical instrument and the leg 10 along being shorter than leg 10 diameters of directrix A or B intersects.Thus, consider the space that should exist, connector element is installed in order to permission between the limit of fenestra 25 portion and leg 10, this location of leg allows to interrupt ripple 20 and 21 described in each in a distance, wherein said distance is shorter compared with such situation: this situation be directrix A or B along the maximum transverse size of leg, under the situation of circular cross-section, be its diameter, intersect with leg.Therefore consider that these interruptions can reduce partly the pliability of sealing barrier and help partly its fatigability and its abrasiveness, thereby the ripple that interrupts sealing barrier in short as far as possible distance is favourable.
Under the situation of circular cross-section, leg provides optimum effect in half distance between the ripple 20 interrupting and the centering of half distance between the ripple 21 of interruption.But, also can consider other location and other sectional shape of leg.The principle that can be used at every turn adapting to the location of leg between ripple is to select such position: described position minimizes or at least reduce the transverse dimension of the leg crossing with the directrix of interrupting ripple.In the specific distribution of the geometry in particular of leg and/or the ripple of film, requiring in different length, to interrupt under the situation of a plurality of ripples, can be to grow the length of interruption most or the cumulative length of the interruption that obtains for adapting to the suitable Optimal Parameters of leg location.
On Fig. 3, fenestra 25 has square configuration, its convenient shape that sealing plate 11 is cut into expectation.But, also can implement other shape of fenestra, particularly according to the geometrical shape of leg.
With reference to Fig. 4, to Fig. 8, now the detailed mode of execution of the container wall in the region of leg 10 will be described in.This mode of execution is particularly suitable for the container that container wall comprises two sealing barriers and two heat shields.Sealing barrier 6 thereby will be called as primary seal barrier.To only describe near leg 10, container wall can be implemented according to the instruction of patent application FR-A-2781557 in addition.
Fig. 4 is at leg 10 described in middle erection stage with around section half view of the substantially square container wall region of this leg.What expression was divided in right side is that what left part represented is after these elements are installed before the element of secondary sealing barrier and main heat shield is installed.
For being connected to secondary sealing barrier, leg 10 comprises bracket panel body 23, and bracket panel body 23 is square, fixing around part 13 under truncated cone shape at the height of the upper surface of the very thin secondary sealing barrier of correspondence and secondary heat shield 22.For being connected to primary seal barrier, leg 10 comprises master body 24, and master body 24 is rounded, fixing around part 13 under truncated cone shape at the height of the upper surface of the main heat shield 26 of correspondence.Disk body 23 can be to implement with 10 one-tenth single unitarily formed modes of leg with 24.
Below bracket panel body 23, secondary heat shield 22 comprises glass wool filler 27, and glass wool filler 27 also has square gabarit.Below master body 24, main heat shield 26 comprises glass wool filler 28, and glass wool filler 28 also has circular gabarit.
Around filler 27 and disk body 23, utilize four gussets to implement secondary heat shield, secondary sealing barrier and main heat shield, one of gusset is visible in the part of the right side of Fig. 4, figure notation is 30.One gusset 30 has L shaped stairstepping generally, with: L-shaped lower heat insulation block 31, it forms an element of secondary heat shield 22; Flexible sealing coating 32, the L-shaped upper surface of its complete covering blocks 31; The L-shaped upper heat insulation block 33 less with size, it forms an element of main heat shield 26.Upper block 33 aligns with the outer side surface of lower block 31, to make to be positioned at the end edge of lower block 31 and sealing coating 32 regions on inward flange expose.Gusset 30 can with same patent application FR-A-2781557 in the similar material of the material of instructing glued joint to come prefabricated, described material is especially for the urethane foam of heat shield and wood veneer with for aluminium foil and the glass fiber compound material of secondary sealing barrier.
Four gussets 30 enclose the profile of filler 27 and disk body 23 by their inner side surface ring.The size of lower block 31 is designed to produce space between them, and these spaces are the form of four radial channels 34, and it is at every turn between the end face of two adjacent lower blocks 31.For guaranteeing the continuity of main heat shield 22, with glass fibre membrane 35 each conduit 34 of filling.The porosity of the glass fibre of filler 27 and glass fibre membrane 35 makes gas become possibility through the circulation of main heat shield 22, particularly in order to the nitrogen deactivation of container wall.
Fig. 6 illustrates the enforcement of secondary sealing barrier in leg 10 regions with plan view.For realizing secondary sealing barrier around the continuity of leg 10, four aluminium foils and fiberglass sealed composite material tape 36 be bonded on bracket panel body 23 and the sealing coating 32 of gusset 30 on.One band 36 is oriented to overlap with the inward flange of an avris of bracket panel body 23 and the exposure of two lower blocks 31 at every turn.These are with 36 at the end regions 37 mutual crossovers in place.For realizing the continuity of secondary sealing barrier above conduit 34, four aluminium foils and fiberglass sealed composite material tape 38 are bonded on the sealing coating 32 of gusset 30, each to overlap with the end edge of two lower blocks 31.
Fig. 7 is illustrated in main heat shield same containers wall region is afterwards installed.Its between upper heat insulation block 33 and leg 10, utilize four dihedral blocks 40 and four in the middle of blocks 41 complete, at every turn the fit circular contour of filler 28 and master body 24 of the inner side surface of these blocks.These blocks 40 and 41 also illustrate in the left part of Fig. 4.
As visible in the details of Fig. 5, the upper surface of middle block 41 has the groove 44 being defined by a recess 43 at every turn.Groove 44 is definitely at master body 24 height, and smooth supporting surface is provided to metal shrouding 45, metal shrouding 45 is for implementing primary seal barrier around leg 10.
As visible on Fig. 7, two shroudings 45 around master body 24 arrange and whole week of master body along on seal welding in master body.For this reason, shrouding 45 is the cut semicircular in shape in limit portion 46 places within it, and that the edge portion 47 of shrouding defines is square, and this square size is slightly larger than the fenestra 25 arranging in ripple sealing plate 11.Two shroudings 45 in region 48 places stacked, in region, these two shroudings of 48 places are welded together.The block 40 and 41 that shrouding 45 is fixed in main heat shield by being arranged near the rivet of shrouding edge portion 47 or wood screw 49, so that shrouding 45 is close to these blocks, particularly owing to need to avoiding shrouding to dig when shrouding is welded on master body 24.
Get back to Fig. 2 and Fig. 3, can see: on the one hand by the limit portion that defines the sealing plate 11 of fenestra 25 is welded on shrouding 45, by be sealed shut the ripple 20 of interruption and 21 end with termination case 50, in leg 10 regions, complete primary seal barrier 6 on the other hand.The cutting of enforcement to sealing plate 11, to cover the shrouding 45 limit portions that comprise screw 49.
One embodiment of termination case 50 is shown on Fig. 8.Termination case 50 comprises: be a base plate of two parts 51 and 52, described two parts are for being welded on hermetically respectively on shrouding 45 and sealing plate 11; With a housing 54, for being welded on hermetically the end of ripple 20 or 21.Recess 53 between the part 51 and 52 of base plate has the amplitude (amplitude) that substantially equals sealing plate 11 thickness.
For form secondary heat shield, secondary sealing barrier and main heat shield to the heat insulation block illustrating and the cutting of other prefabricated elements on Fig. 2, Fig. 4, Fig. 6 and Fig. 7, be only schematic.Can be according to other shape cutting and prefabricated similar components, so that the more or less basic component of the installation requirement of container wall.According to other mode of execution of correspondence, four L-shaped gussets 30 are substituted by two U-shaped plates or the single plate with quadra shape.
As more clearly visible on Fig. 3, the leg above considered needs such fenestra: the size of fenestra is approximately equal to the twice at two intervals 55 between ripple 15 or 16, and described ripple is equidistant here.For this reason, two of each series ripples are interrupted.But, near leg and container wall this layout leg can be suitable for other size of leg.For example, for more roomy leg, corresponding fenestra can interrupt the ripple of the more more number in or each series, for example three or four ripples or more ripple.In addition, also can move partly the trend of some ripple, with limit should interrupted ripple number, and thereby retain the higher spring level of sealing film.This possibility illustrates by the mode of execution of Fig. 9.
On Fig. 9, with identical figure notation, add that 100 represent with the same or analogous element of Fig. 3 element.The transverse dimension of leg 110 is larger, for example be more than or equal to approximately three times of interval 155 between ripple 115 or 116, be disposed in the fenestra 125 passing through in the film of corrugated metal, in order to leg 110, interrupt in this case the directrix of corresponding four ripples in each series.But, this mode of execution does not interrupt four ripples in each series, but arrange, interrupt two ripples 120 of each series, corresponding ripple 121 as in aforesaid mode of execution, and another two ripples 158 of each series, corresponding ripple 159 are setovered partly away from leg 110 with respect to its original directrix, but are not interrupted in a word.
For this reason, sealing barrier 106 is changed at concentric two square fenestras 125 and 160 places.Outside fenestra 160, sealing barrier 106 is comprised of the sealing plate 111 of the longitudinal ripple 115 with being equally spaced and transverse wave 116.Between fenestra 160 and fenestra 125, sealing barrier 106 continues mutually with other ripple sealing plate, other ripple sealing plate is the c-shaped ripple sealing plate 161 generally of two in this situation, they with distribute by different way, i.e. the nearer ripple in interval in this situation.Especially, the ripple of sealing plate 161 forms the central segment portion 162 away from leg 110 biasings for every ripple 158, corresponding ripple 159, corresponding central segment portion 163.Finally, similar at the structure of sealing barrier 106 and the mode of execution of Fig. 3 of fenestra 125 places and portion within it.
For implement ripple 158 or 159 central segment portion 162 or 163 with corrugated portion outside fenestra 160 between at the engaging of fenestra 160 places, use bent member 170.
One embodiment of bent member 170 is shown on Figure 10.Bent member 170 comprises: a base plate, and it is two parts 171 and 172, and these two parts are for being welded on hermetically respectively on the plate 111 or 161 of sealing barrier 106 and adjacent bent member 170; With curved elbow ripple 174, its directrix forms selected angle, for example 135 °.Curved elbow ripple 174 is for being connected to hermetically the adjacent end portion of ripple 158 or 159 and the curved elbow ripple of adjacent bent member.Recess 173 between the part 171 and 172 of base plate has and substantially equals for making sealing plate 111 or 161 or the amplitude of the thickness of the sheet material of bent member 170.Preferably, for these different members, adopt the sheet material of same thickness.
At another mode of execution not showing, be for example suitable in another mode of execution of the leg that diameter is less, fenestra interrupts all ripples of its directrix, two ripples of each series on for example Fig. 3, with ripple 158 and the 159 similar ground of Fig. 9, along the trend of biasing, kept away (à travers) fenestra and extended.In this embodiment, the pliability of film can be improved, and this is because finally do not interrupt any ripple at leg place termination case.
In mode of execution mentioned above, primary seal barrier is implemented to have the sheet metal of orthogonal two serial ripples.But, can similarly use and have still less or more ripple and/or there is the corrugated metal film of other type that different ripples arranges.
