Description
7810450-2 re skalet brister. För detta ändamål har föreslagits att det yttre skalet skall tillverkas av dyrbara, högvärdiga material såsom exempelvis 9%-nickelstål eller betong som är förspänd med särskild armering. 7810450-2 re shell bursts. For this purpose, it has been suggested that the outer shell must be made of expensive, high-quality materials such as, for example, 9% nickel steel or prestressed concrete with special reinforcement.
Föreliggande uppfinning avser en behållare för kondenserad gas, vilken är billigare och dessutom erbjuder större säkerhet än de kända behållarna för lagring av kondenserad gas.The present invention relates to a container for liquefied gas, which is cheaper and also offers greater security than those known containers for storing liquefied gas.
Behållaren enligt uppfinningen innefattar ett yttre skal med en betongbottenvägg och en betongsidovägg, jordmaterial som lig- ger mot utsidan av betongsidoväggen, polyuretanskum anordnat på insidan av betongsidoväggen, belastningsbärande värmeisóle- rande material anordnat på insidan av betongbottenväggen, en innertank, vilken är tillverkad av ett material som motstår den låga temperaturen för den kondenserade gas som skall lagras, vilken innefattar en bottenvägg och en sidovägg och vilken är anordnad innanför det yttre skalet av betong på sådant sätt att bottenväggen av innertanken uppbäres av det belastningsbärande värmeisolerande materialet, ett förhållandevis stort ringformat rum mellan polyuretanskummet på betongsidoväggen och sidoväg- gen av innertanken, ett värmeisolerat tak tätande insidan av innertanken och av det yttre skalet mot omgivningen, samt en förbindelse mellan den övre delen av innertanken och det ringformade rummet.The container according to the invention comprises an outer shell with a concrete bottom wall and a concrete side wall, soil material provides against the outside of the concrete side wall, polyurethane foam arranged on the inside of the concrete side wall, load-bearing thermal insulation material arranged on the inside of the concrete bottom wall, a inner tank, which is made of a material that resists it low temperature of the liquefied gas to be stored, which comprises a bottom wall and a side wall and which is arranged inside the outer shell of concrete in such a way that the bottom wall of the inner tank is supported by the load-bearing heat-insulating material, a relatively large annular format between the polyurethane foam on the concrete sidewall and the sidewall gen of the inner tank, a heat-insulated roof sealing the inside of the inner tank and of the outer shell towards the surroundings, and a connection between the upper part of the inner tank and it annular room.
Betongsidoväggen av det yttre skalet är på insidan belagt med polyuretanskum, företrädesvis styvt polyuretanskum med slutna celler. Detta material erbjuder god värmeisolering och god tätning så att gasen eller den kondenserade gasen inte når be- tongsidoväggen. Det yttre skalet är framställt av armerad betong och omges av jordmaterial som på sin översida kan vara täckt med skikt av asfalt som används i syfte att förhindra rörelser i och vittring av jordmaterialet.The concrete side wall of the outer shell is coated on the inside polyurethane foam, preferably rigid polyurethane foam with closed cells. This material offers good thermal insulation and good seal so that the gas or liquefied gas does not reach the the tongue side wall. The outer shell is made of reinforced concrete and is surrounded by soil material which may be covered on its upper surface with layers of asphalt used for the purpose of preventing movement in and weathering of the soil material.
Användning av jordmaterialet innebär dels den fördelen att be- tongsidoväggen inte behöver förspännas med särskild armering och dels den fördelen att jordmaterialet bildar en tillkommande "781Ûlæ50-2 spärr mot den kondenserade gasen.The use of the soil material entails the advantage of the side wall does not need to be prestressed with special reinforcement and partly the advantage that the soil material forms an additional "781Ûlæ50-2 barrier against the condensed gas.
Vidare är innertanken placerad inuti det yttre skalet av be- tong på sådant sätt att det förekommer ett förhållandevis stort ringformat rum mellan polyuretanskummet på betongsidoväggen och sidoväggen av innertanken. Under normal användning av be- hållaren är det ringformade rummet till följd av förbindelsen mellan ångrummet i innertanken och det ringformade rummet kon- stant fyllt med gas av i huvudsak samma låga temperatur som den i innertanken lagrade kondenserade gasen. Detta innebär den fös- delen att om innertanken skulle läcka eller brista och konden- serad gas strömmar in i det ringformade rummet,kommer det inte att inträffa något plöstligt temperaturfall i uretanskummet och inte heller i betongsidoväggenfvilket minskar sannolikheten för skada av polyuretanskummet och av betongsidoväggen. I det fall innertanken brister kommer konstruktionen dessutom att hindra att det i det ringformade rummet bildas en stor kvanti- tet gas såsom följd av plötslig förångning, vilken gas skulle vara svår att snabbt avlägsna och skulle åstadkomma en plöstlig tryckstegring.Furthermore, the inner tank is located inside the outer shell of the tong in such a way that there is a relatively large annular space between the polyurethane foam on the concrete side wall and the side wall of the inner tank. During normal use of the holder is the annular space due to the connection between the steam space in the inner tank and the annular space constant filled with gas of essentially the same low temperature as that condensed gas stored in the inner tank. This means that the the part that if the inner tank should leak or burst and condense sera gas flows into the annular space, it will not to occur any sudden drop in temperature in the urethane foam nor in the concrete sidewall which reduces the probability for damage to the polyurethane foam and to the concrete side wall. In it In case the inner tank fails, the construction will also prevent the formation of a large quantity in the annular space gas as a result of sudden evaporation, which gas would be difficult to remove quickly and would cause a flaky pressure increase.
En utföringsform av uppfinningen kommer att beskrivas närmare nedan i anslutning till de bifogade ritningar, i vilka fig. l visar en vertikal tvärsektionsvy av en behållare för konaeneerad gas enligt uppfinningen och fig. 2 visar i förstorad skala de .i fig. l markerade detaljerna II och III.An embodiment of the invention will be described in more detail below in connection with the accompanying drawings, in which Fig. 1 shows a vertical cross-sectional view of a container for coneeneered gas according to the invention and Fig. 2 shows on an enlarged scale they Fig. 1 marked details II and III.
Behållaren innefattar ett yttre skal 1 av betong som i sin tur innefattar en betongbottenvägg 2 och en cylindrisk betongsido- vägg 3. Lämpligt.jodrmaterial 4 är anordnat mot utsidan av be- tongsidoväggen 3. dordmaterialet 4, t.ex. sand, är täckt med ett eller flera skikt 14 av asfaltbitumen i syfte att förhindra rörelser i och vittring av jordmaterialet.The container comprises an outer shell 1 of concrete which in turn comprises a concrete bottom wall 2 and a cylindrical concrete side wall 3. Suitable.your material 4 is arranged on the outside of the the tongue side wall 3. the mandrel material 4, e.g. sand, is covered with one or more layers 14 of asphalt bitumen in order to prevent movements in and weathering of the soil material.
Ytterytan av betongsidoväggen 3 är försedd med en lämplig, icke visad, beläggning, t.ex. ett bitumenskikt, ett färgskikt, ett epoxiplastskikt eller ett polyuretanskikt, som tätar betongsi- 781Ûl+50-2 doväggen 3 vätsketätt mot jordmaterialet 4. På insidan av be- tongsidoväggen 3 är ett kontinuerligt, värmeisolerande skikt 5 av polyuretanskum, företrädesvis styvt polyuretanskum med slutna celler, anordnat. Detta skikt 5 kan vara pâfört exem- pelvis genom sprutning. Polyuretanskummet är av sådan kvali- tet att skiktet 5 i praktiken kan anses vara ogenomträngligt för den kondenserade gasen och för gasen. Tjockleken av skik- tet 5 är beroende dels av den kondenserade gas som skall lag- ras i behållaren och dels av den temperatur som skall vidmakt- hållas i behållaren. Mellan skiktet 5 och betongsidoväggen 3 kan en icke visad vatten- och ångspärr finnas anordnad och den- na kan bestå av ett skikt av epoxiplast eller av ett polyure- tanskikt eller av tunna plåtar av kolstâl, av kryogeniskt stål såsom exempelvis nickelstål eller invarstål, eller av aluminium.The outer surface of the concrete side wall 3 is provided with a suitable, non shown, coating, e.g. a bitumen layer, a paint layer, a epoxy plastic layer or a polyurethane layer, which seals the concrete 781Ul + 50-2 dove wall 3 liquid-tight against the soil material 4. On the inside of the the tongue side wall 3 is a continuous, heat-insulating layer Of polyurethane foam, preferably rigid polyurethane foam with closed cells, arranged. This layer 5 may be applied e.g. pelvis by spraying. The polyurethane foam is of such quality that the layer 5 can in practice be considered impermeable for the liquefied gas and for the gas. The thickness of the custom 5 depends in part on the liquefied gas to be in the container and partly by the temperature to be maintained kept in the container. Between the layer 5 and the concrete side wall 3 a water and vapor barrier (not shown) may be provided and the may consist of a layer of epoxy plastic or of a polyurethane dental layers or of thin sheets of carbon steel, of cryogenic steel such as, for example, nickel steel or stainless steel, or of aluminum.
Betongbottenväggen 2 är klädd med ett lämpligt belastningsbä- rande värmeisolerande material 6, t.ex. skumglas eller något annat ekvivalent material. Inuti det yttre skalet l av betong är en innertank 7 anordnad, vilken innefattar en bottenvägg 8 och en cylindrisk sidovägg 9. Innerväggen 7 är framställd av ett material som är anpassat för att innehålla den kalla kon- denserade gasen, t.ex 9%-nickelstål, aluminium, segt kol- stål eller annat lämpligt material som motstår låga tempera- turer. Bottenväggen 8 av innertanken 7 vilar på det belast- ningsbärande värmeisolerande materialet 6. Mellan skiktet 5 och sidoväggen 9 finns ett förhållandevis stort ringformat rum 10. Insidan av innertanken 7 och av det yttre skalet l är tätad mot omgivningen med hjälp av en värmeisolerad takkonstruk- tion 11, 12, 13, 16 innefattande ett aåmfemet tak, vilket här ett horisontellt värmeisolerat däck 12 med hjälp av Stöttor l3.The concrete bottom wall 2 is clad with a suitable load heat insulating material 6, e.g. foam glass or something other equivalent material. Inside the outer shell l of concrete an inner tank 7 is arranged, which comprises a bottom wall 8 and a cylindrical side wall 9. The inner wall 7 is made of a material adapted to contain the cold con- densified gas, eg 9% nickel steel, aluminum, tough carbon steel or other suitable material that withstands low temperatures tours. The bottom wall 8 of the inner tank 7 rests on the load heat-insulating material 6. Between the layer 5 and the side wall 9 there is a relatively large annular space 10. The inside of the inner tank 7 and of the outer shell 1 is sealed to the environment by means of a heat-insulated roof construction tion 11, 12, 13, 16 comprising a reinforced roof, which here a horizontally heat-insulated tire 12 by means of Supports l3.
Det dâm-formade taket ll uppbäres i sin tur av en yttervägg 15 av stål vilken är nedsänkt i betongsidoväggen 3. Det horison- tella däcket 12 är på sin översida försedd med ett lämpligt värmeisolerande material 16, t.ex. ett skikt av glasfibermate- rial eller sknmglas eller polyuretanskum. Takkonstruktionen är vidare försedd med icke visade, konventionella säkerhetsventi- ler, vilka hindrar trycket i tanken från att överskrida ett ön- '7810450-2 skat tryck. Översidan av sidoväggen 9 och det horisontella däcket 12 ligger på visst avstånd från varandra på sådant sätt att en förbindel- se bildas mellan ångrummet i innertanken 7 och det ringformade rummet l0. Som framgår av ritningen har betongsidoväggen 3 en nedåt ökande tjocklek med tanke på det belastningar som skall absorberas av sidoväggen 3 i det fall ett fel uppstår på in- nertanken 7.The dam-shaped roof 11 is in turn supported by an outer wall 15 of steel which is immersed in the concrete side wall 3. The horizontal tella tire 12 is provided on its upper side with a suitable heat insulating material 16, e.g. a layer of fiberglass material rial or stained glass or polyurethane foam. The roof construction is further provided with conventional safety vents (not shown) which prevent the pressure in the tank from exceeding an '7810450-2 tax pressure. The top of the side wall 9 and the horizontal deck 12 are located at a certain distance from each other in such a way that a see is formed between the steam space in the inner tank 7 and the annular one room l0. As can be seen from the drawing, the concrete side wall 3 has a downward increasing thickness in view of the loads to be absorbed by the side wall 3 in the event of a fault in the nertanken 7.
Tanken är vidare försedd med icke visade, konventionella organ för påfyllning och uttömning av kondenserad gas.The tank is further provided with conventional means (not shown) for filling and discharging liquefied gas.
I syfte att hålla utsidan av betongsidoväggen 3 och av betong- bottenväggen 2 på en konstant, lämplig temperatum t.ex. ca 5°C, och i syfte att hindra jordmaterialet 4 från att frysa är betongsidoväggen 3 och betonghottenväggen 2 försedda med icke visade värmeelement, vilka matas exempelvis med varm vätska el- ler med elektricitet.In order to keep the outside of the concrete side wall 3 and of the concrete the bottom wall 2 at a constant, suitable temperature e.g. ca 5 ° C, and in order to prevent the soil material 4 from freezing is the concrete side wall 3 and the concrete bottom wall 2 provided with no shown heating elements, which are fed, for example, with hot liquid or clay with electricity.
Under normal användning innehåller innertanken 7 kondenserad gas och gas finns över vätskenivån i innertanken 7. Tack vare 0 förbindelsen mellan översidan av sidoväggen 9 och det horison- tella däcket 12 kan nämnda gas strömma till det ringformade rummet 10 mellan sidoväggen 9 och skiktet 5 av polyuretanskum.During normal use, the inner tank 7 contains condensed gas and gas are above the liquid level in the inner tank 7. Thanks The connection between the upper side of the side wall 9 and the horizontal tle the tire 12, said gas can flow to the annular the space 10 between the side wall 9 and the layer 5 of polyurethane foam.
På detta sätt hålles insidan av skumskiktet 5 konstant vid i huvudsak samma låga temperatur som den i innertanken 7 rådande temperaturen. En fördel med detta är att om innertanken 7 skul- le brista eller börja läcka, varvid kondenserad gas skulle strömma in i det ringformade rummet 10, kommer inte något plötsligt temperaturfall i skumskiktet 5 eller i betongsidoväg- gen 3 att inträffa,varför sannolikheten för att skumskiktet 5 och betongsidoväggen 3 skadas, kommer att minskas. En annan . fördel med detta är att i det fall kondenserad gas kommer in i det ringformade rummet 10 till följd av att innertanken 7 brister eller börjar läcka kommer inte någon plötslig förâng- ning av den kondenserade gasen att inträffa i det ringformade rummet 10 och därmed undvikes en därmed sammanhängande plöts- lig tryckstegring. 7810450-2 Om innertanken 7 brister eller börjar läcka hindrar skiktet 5 av polyuretanskum på betongsidoväggen 3 den kondenserade ga- sen att komma i direkt kontakt med betongsidoväggen 3.In this way, the inside of the foam layer 5 is kept constant at i essentially the same low temperature as that prevailing in the inner tank 7 the temperature. An advantage of this is that if the inner tank 7 smile burst or begin to leak, whereby condensed gas would flow into the annular space 10, nothing will come sudden drop in temperature in the foam layer 5 or in the concrete side road gene 3 to occur, hence the probability that the foam layer 5 and the concrete side wall 3 is damaged, will be reduced. Another . advantage of this is that in case condensed gas enters in the annular space 10 due to the inner tank 7 defects or starts to leak, there will be no sudden evaporation the condensed gas to occur in the annular gas room 10 and thus avoids an associated sudden pressure increase. 7810450-2 If the inner tank 7 breaks or starts to leak, the layer 5 obstructs of polyurethane foam on the concrete side wall 3 the condensed gas then come into direct contact with the concrete side wall 3.
I syfte att förhindra skador på betongsidoväggen 3 till följd av avkylning och till följd av det plötsliga vätsketryck som skulle verka på betongväggen 3 om innertanken 7 skulle brista är betongsidoväggen 3 förspänd med hjälp av jordmaterialet 4.In order to prevent damage to the concrete side wall 3 as a result of cooling and due to the sudden fluid pressure that would act on the concrete wall 3 if the inner tank 7 were to rupture the concrete side wall 3 is prestressed by means of the soil material 4.
Detta medför den fördelen att betongsidoväggen 3 inte behöver förspännas med hjälp av härför avsedd särskild armering. En an- nan fördel med att jordmaterialet 4 ligger mot betongsidoväg- gen 3 är att det bildar en ytterligare spärr mot den kondense- rade gasen, vilket ytterligare ökar säkerheten. Det yttre ska- let l är försett med en förstärkning av normalt kolstâl eller av 9% nickelstål eller av rostfritt stål.This has the advantage that the concrete side wall 3 does not have to prestressed by means of special reinforcement intended for this purpose. An an- advantage that the soil material 4 lies against the concrete side road gene 3 is that it forms an additional barrier against the condensate gas, which further increases safety. The outer shell let l is provided with a reinforcement of normal carbon steel or of 9% nickel steel or of stainless steel.
Det bör observeras att förbindelsen mellan gasrummet i inner- tanken 7 och det ringformade rummet 9 även kan åstadkommas med hjälp av icke visade öppningar i det övre partiet av sidoväg- gen 9. I detta fall kan sidoväggen 9 sträcka sig upp mot det ' horisonetlla däcket 12.It should be noted that the connection between the gas space in the the tank 7 and the annular space 9 can also be provided with by means of openings not shown in the upper part of the side road gen 9. In this case, the side wall 9 may extend upwards towards it 'Horizontal tire 12.
Det bör observeras att behållaren enligt uppfinningen inte be- höver ha cylindrisk form. Om så önskas kan andra former väljas men den cylindriska formen är den föredragna.It should be noted that the container according to the invention is not need to have a cylindrical shape. If desired, other shapes can be selected but the cylindrical shape is the preferred one.
Om så önksas kan skalet l av betong vara helt eller delvis in- bäddat i marken.If desired, the concrete shell 1 may be wholly or partly embedded in the ground.
I den beskrivna utföringsformen är det ringformade rummets 10 betongbotten inte försedd med värmeisolerande material. Emel- lertid föredras att anordna värmeisolerande material även på botten av det ringformade rummet, t.ex. skumglas eller styvt polyuretanskum av hög täthet och med hög hållfasthet, företrä- desvis polyuretanskum med slutna celler. 7810160-2 I de flesta fall kan det ringformade rummet 10 lämnas tomt. Om emellertid kondensrade gaser lagras vid mycket låga temperatu- rer, exempelvis kondenserad naturgas vid ca -l60°C, kan det vara ekonomiskt attraktivt att fylla det ringformade rummet l0 partiellt eller fullständigt med ett löst isoleringsmaterial, t.ex. perlit.In the described embodiment, the annular space 10 is the concrete base is not provided with heat-insulating material. Emel- however, it is preferred to arrange heat insulating materials also on the bottom of the annular space, e.g. foam glass or rigid high density, high strength polyurethane foam, preferably also closed cell polyurethane foam. 7810160-2 In most cases, the annular space 10 can be left empty. If however, condensed gases are stored at very low temperatures. for example, liquefied natural gas at about -160 ° C, it can be economically attractive to fill the annular space l0 partially or completely with a loose insulating material, for example perlite.
