Description

독립형 액화가스 저장탱크의 교차적층 된 진공단열패널의 연결 구조{CROSS STACKED INSULATION PANEL INSTALLATION STRUCTURE OF INDEPENDENT TYPE LIQUEFIED GAS STORAGE TANK}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connection structure of a cross-laminated vacuum insulation panel of a stand-alone liquefied gas storage tank,

본 발명은 LNG나 LPG 등의 액화가스를 저장하기 위해 설치되는 독립형 액화가스 저장 탱크의 진공단열패널의 연결구조에 관한 것이다.The present invention relates to a connection structure of a vacuum insulation panel of a stand-alone liquefied gas storage tank installed to store liquefied gas such as LNG or LPG.

천연가스는 육상 또는 해상의 가스배관을 통해 가스 상태로 운반되거나, 액화천연가스(LNG) 또는 액화석유가스(LPG)의 상태로 수송선에 저장된 채 원거리의 소비처로 운반된다. LNG는 메탄이 주성분인 천연가스를 대기압에서 영하 162℃로 액화시킨 것으로, 액체와 기체의 용적비율은 약 1/600이고, 액화 상태의 비중은 0.43~0.50이다.Natural gas is transported in the form of gas via land or sea gas pipelines, or transported to remote sources of consumption in the form of liquefied natural gas (LNG) or liquefied petroleum gas (LPG) stored in transports. LNG is a methane-liquefied natural gas which is liquefied at -160 ° C at atmospheric pressure. The volume ratio of liquid to gas is about 1/600, and the specific gravity of the liquefied state is 0.43-0.50.

LNG를 싣고 바다를 운항하여 육상 소요처에 LNG를 하역하기 위한 LNG 수송선이나, LNG를 싣고 바다를 운항하여 육상 소요처에 도착한 후 저장된 LNG를 재기화하여 천연가스 상태로 하역하는 LNG RV(Regasification Vessel)는 액화천연가스의 극저온에 견딜 수 있는 저장탱크(흔히, ‘화물창’이라고 함)를 포함한다.LNG transport vessels that transport LNG to the sea, and LNG transport vessels that transport LNG to the sea, and LNG RVs (Regasification Vessel ) Contains a cryogenic storage tank (often referred to as a 'hold') of liquefied natural gas.

이 저장탱크는 단열재에 화물의 하중이 직접적으로 작용하는지 여부에 따라 독립형(Independent Type)과 멤브레인형(Membrane Type)으로 분류할 수 있으며, 통상 멤브레인형 저장탱크는 No 96형과 Mark III형으로 나눠지고, 독립형 저장탱크는 MOSS형과 SPB형으로 나눠진다. MOSS형의 독립형 저장탱크의 구조는 대한민국 특허 제10-15063호 등에 기재되어 있고, SPB형의 독립형 저장탱크의 구조는 대한민국 특허 제10-30513호 등에 기재되어 있다.This storage tank can be classified into independent type and membrane type depending on whether the load of the cargo directly acts on the insulation material. Usually, the membrane type storage tank is divided into No. 96 type and Mark III type The stand-alone storage tanks are divided into MOSS type and SPB type. The structure of the MOSS type independent storage tank is described in Korean Patent No. 10-15063 and the structure of the SPB type independent storage tank is described in Korean Patent No. 10-30513.

일반적으로 독립형 저장탱크는 알루미늄 합금이나 SUS 및 9% 니켈 등 저온에 강한 합금으로 제조된 탱크 몸체에 폴리우레탄 폼과 같은 비교적 단단한 단열 패널을 부착시켜 만들어지며, 선체의 내부바닥에 배열되는 복수의 탱크 지지체 상에 놓여진다.Generally, a stand-alone storage tank is made by attaching a relatively hard insulating panel such as a polyurethane foam to a tank body made of an alloy such as aluminum alloy or SUS and 9% nickel and resistant to low temperature, and a plurality of tanks Is placed on a support.

폴리우레탄 폼에 의해 제조된 다수의 단열패널이 탱크 몸체의 외부에 설치되는 액화가스 저장탱크의 단열구조는 대한민국 특허 제10-166608호 등에 기재되어 있다.A heat insulating structure of a liquefied gas storage tank in which a plurality of heat insulating panels manufactured by a polyurethane foam is provided outside the tank body is described in Korean Patent No. 10-166608.

이러한 종래기술에 따르면 액화가스 저장탱크의 단열구조는 단열패널이 소정의 두께를 가져야 하기 때문에, 단열 패널 설치 시 하나의 단열 패널의 크기를 일정수준 이상으로 증가시키지 못하는 한계가 있다. 이러한 문제를 해결하기 위하여, 대한민국 공개특허 10-2011-0051407, 10-2011-0046627 등에서는 스터드 볼트와 상기 스터드 볼트에 끼워지는 1차 단열패널과 상기 1차 단열패널을 고정적으로 유지하기 위해 상기 스터드 볼트에 결합되는 고정부재와 상기 고정부재에 결합되어 상기 1차 단열패널 상에 적층되는 2차 단열패널을 포함하는 것을 제공한다. According to such prior art, the heat insulating structure of the liquefied gas storage tank has a limitation in that the size of one heat insulating panel can not be increased to a certain level or more at the time of installing the heat insulating panel because the heat insulating panel must have a predetermined thickness. In order to solve such a problem, Korean Unexamined Patent Publication Nos. 10-2011-0051407 and 10-2011-0046627 disclose a stud bolt, a primary insulation panel fitted to the stud bolt, A fixing member coupled to the bolt, and a secondary insulation panel coupled to the fixing member and stacked on the primary insulation panel.

하지만, 상기 단열패널이 고정부재와 같은 장착부재에 의해 연장될 때, 상기 단열패널의 경계면이 일직선 상으로 적층되므로 대기로부터의 열이 탱크표면까지 도달하는 길이가 짧아 단열성능이 떨어진다. 또한, 스터드 볼트와 고정부재, 그리고, 이를 단열재와 같은 충전부재로 채우지만 그 틈새를 통해 대기로부터 탱크표면으로 열이 침투할 수 있으므로 단열이 완벽하게 이루어지지 않는다.However, when the heat insulating panel is extended by a mounting member such as a fixing member, since the boundary surface of the heat insulating panel is stacked in a straight line, the length of heat from the atmosphere reaching the surface of the tank is short, In addition, although the stud bolt and the fixing member are filled with a filling member such as an insulating material, heat can penetrate from the atmosphere to the tank surface through the gap, so that the insulation is not completely achieved.

본 발명은 상기한 종래의 문제점들을 개선하기 위한 것으로, 탱크몸체에 진공단열패널을 교차적층함으로써 상기 진공단열패널의 경계면을 따라 대기로부터의 열이 탱크 표면까지 도달하는 길이가 길어 단열성능이 개선되고, 단열패널의 두께를 얇게 하면서도 강화된 단열성능을 가질 수 있는 독립형 액화가스 저장탱크의 교차적층 된 진공단열패널의 연결 구조를 제공하고자 하는 것이다.SUMMARY OF THE INVENTION It is an object of the present invention to improve the above-described problems of the prior art by providing a vacuum insulation panel on a tank body by cross-lamination so that heat from the atmosphere along the boundary surface of the vacuum insulation panel reaches the tank surface, And to provide a connection structure of a cross-laminated vacuum insulation panel of a self-contained liquefied gas storage tank capable of having enhanced insulation performance while reducing the thickness of the insulation panel.

도 1에는 본 발명의 바람직한 실시형태에 따른 진공단열패널의 연결구조를 설명하기 위해 단면도가 도시되어 있고, 도 2에는 탱크 몸체의 외부에 장착부재와 진공단열패널이 연결되는 과정을 순서대로 도시화되어 있다.FIG. 1 is a cross-sectional view illustrating a connection structure of a vacuum insulation panel according to a preferred embodiment of the present invention. FIG. 2 shows a process of connecting a mounting member and a vacuum insulation panel to the outside of a tank body, have.

도 1 및 도 2에 도시된 바와 같이, 독립형 액화가스 탱크의 단열구조는 탱크 몸체(1)의 외부에 진공단열패널(6)이 적층됨으로써 진공단열패널층을 형성하여 이루어진다. 상기 진공단열패널(6)은 열전도율이 매우 낮은 단열재로서 알루미늄 박막을 포함하는 높은 차폐성을 갖는 외피가 내부에 유기계나 무기계열의 기공형 심재의 모든 면을 둘러싸도록 형성된다. 상기 진공단열패널(6)은 저장탱크의 탱크 몸체(1) 외측으로 복수개가 서로 연달아 인접되게 배치되어 하부 진공단열패널층(6a)을 형성하고 상기 하부 진공단열패널층(6a) 위에 진공단열패널이 하나 이상의 층으로 교차적층됨으로써 상부 진공단열패널층(6b)을 형성한다.  As shown in FIGS. 1 and 2, the heat insulating structure of the independent liquefied gas tank is formed by depositing a vacuum insulating panel 6 on the exterior of the tank body 1 to form a vacuum insulating panel layer. The vacuum insulating panel 6 is formed as a heat insulating material having a very low thermal conductivity such that an enclosure having a high shielding property including an aluminum thin film surrounds all the surfaces of the organic or inorganic pore core. A plurality of vacuum heat insulating panels 6 are disposed adjacently to each other outside the tank body 1 of the storage tank to form a lower vacuum insulating panel layer 6a and a vacuum insulated panel layer 6b is formed on the lower vacuum insulating panel layer 6a, Are stacked one over the other to form the upper vacuum insulating panel layer 6b.

상기의 하부 진공단열패널층(6a)은 탱크 몸체(1)와 밀착되지 않고, 패드(2)에 의해 간극(9)이 형성되어 있다. 탱크 몸체(1)와 하부 진공단열패널층(6a) 사이의 간극(9)은 통기공간으로서 활용될 수 있으며, 탱크 몸체(1)의 손상으로 인한 누출 발생 시 누출액의 통로로서도 활용될 수 있다.The lower vacuum insulation panel layer 6a is not in close contact with the tank body 1 and the gap 9 is formed by the pad 2. [ The gap 9 between the tank body 1 and the lower vacuum insulating panel layer 6a can be utilized as a ventilation space and can also be used as a passage for a leakage liquid in the event of leakage due to damage of the tank body 1 .

본 발명의 바람직한 실시형태에 따른 진공단열패널의 연결구조에 의하면, 탱크 몸체(1)의 외부면에는 일정한 간격을 두고 스터드 볼트(51)가 설치된다. 스터드 볼트(51)는 용접에 의해 탱크 몸체(1)의 외부면에 고정 장착될 수 있다. According to the connection structure of the vacuum insulating panel according to the preferred embodiment of the present invention, the stud bolt 51 is provided on the outer surface of the tank body 1 at a predetermined interval. The stud bolt 51 can be fixedly mounted on the outer surface of the tank body 1 by welding.

스터드 볼트(51) 위에는 소정의 두께를 갖는 패드(2)가 끼워진다. 상기 패드(2)는 둘레에 비해 중앙부위의 높이가 낮게 단차져 있고 중앙에 관통 홈이 형성되어 있다. 그리하여 상기 스터드 볼트(51)는 패드(2)의 단차부위에 형성된 관통홈을 통과하고, 그 위에 스터드 볼트(51)의 말단을 수용하는 제1 고정부재(3)가 나사결합된다. 상기 제1 고정부재(3)는 일측의 하부 말단(52)이 스터드 볼트(51)와 나사결합하여 제1 고정부재(3)의 측면에 형성되는 누름돌기(53)가 패드(2)를 눌러 패드(2)가 탱크 몸체(1)에 밀착되도록 고정한다. 상기 패드(2)의 중앙부에는 하향으로 단차져서 빈 공간(8)으로 이루어지는 단차부위가 형성되어 있다. 그리하여 스터드 볼트(51)를 상기 단차부위로 관통한 후, 제1 고정부재(3)가 끼워져도 제1 고정부재(3)에서 진공단열패널(6)을 누르는 누름돌기(53)가 상기 단차부위의 빈 공간(8)내에 위치하여 하부 진공단열패널층(6a) 진공단열패널(6)을 밀착시켜 장착하는 데 장애가 되지 않는다. A pad 2 having a predetermined thickness is fitted on the stud bolt 51. The pad 2 has a height lower than that of the central portion, and a through hole is formed at the center. Thus, the stud bolt 51 passes through a through groove formed in the stepped portion of the pad 2, and a first fixing member 3, which receives the end of the stud bolt 51, is screwed thereon. The lower end 52 of the first fixing member 3 is screwed to the stud bolt 51 so that the pressing protrusion 53 formed on the side surface of the first fixing member 3 presses the pad 2 The pad 2 is fixed so as to be in close contact with the tank body 1. At the central portion of the pad 2, a stepped portion formed by a step downwardly and having an empty space 8 is formed. The pressing projection 53 for pressing the vacuum insulation panel 6 in the first fixing member 3 even when the first fixing member 3 is inserted after the stud bolt 51 has passed through the stepped portion, It is not a hindrance to closely attach the vacuum insulation panel 6 to the lower vacuum insulation panel layer 6a.

상기 제1 고정부재(3)에서 스터드 볼트(51)가 결합되는 부위인 하부 말단(52)의 반대측인 상부 말단(54)에는 제2 고정부재(4)의 하부 말단(71)이 수용되도록 연장 나사산이 형성된다. A lower end 71 of the second fixing member 4 is received in an upper end 54 of the first fixing member 3 opposite to a lower end 52 of the stud bolt 51, Threads are formed.

상기 패드(2) 위에는 하부 진공단열패널 층(6a)을 진공단열패널(6)의 모서리들이 안착되어 고정된다. 다시 말해서 하부 진공단열패널층(6a)을 형성하는 진공단열패널(6)의 각 모서리들은 각각 서로 다른 패드(2) 위에 안착되어 고정된다. 즉, 상기 패드(2)는 진공단열패널(6)의 모서리가 만나는 정점 부분을 수용하고, 상기 진공단열패널(6)의 다른 모서리가 만나는 정점 부분은 또 다른 패드(2)가 이를 수용한다. 상기 진공단열패널(6)은 일정한 간격으로 설치된 패드(2) 위에 연달아 장착되어 탱크 몸체(1)를 감싸고, 패드(2)에 의해 탱크 몸체(1)와 진공단열패널(6) 사이에서 간극(9)의 크기가 일정하게 유지될 수 있다. On the pad 2, the lower vacuum insulation panel layer 6a is fixed with the corners of the vacuum insulation panel 6 being seated thereon. In other words, the respective edges of the vacuum insulating panel 6 forming the lower vacuum insulating panel layer 6a are seated and fixed on the different pads 2, respectively. That is, the pad 2 receives the vertex portion where the edge of the vacuum insulation panel 6 meets, and the apex portion where the other edge of the vacuum insulation panel 6 meets is accommodated by another pad 2. The vacuum insulating panel 6 is mounted on a pad 2 provided at regular intervals and encloses the tank body 1 and is sandwiched between the tank body 1 and the vacuum insulating panel 6 by a pad 2 9 can be kept constant in size.

패드(2) 위에 각 모서리가 걸쳐져서 장착된 하부 진공단열패널층(6a)의 진공단열패널(6)은 패드(2)를 고정하고 있는 제1 고정부재(3)에 제2 고정부재(4)가 나사결합되어 고정된다. 상기 제2 고정부재(4)는 판형의 누름판(72)과 상기 누름판(72) 하부에 설치되는 하부말단(71)으로 이루어져서, 제2 고정부재(4)의 하부말단(71)이 제1 고정부재(3)에 결합될 때 상기 누름판(72)이 각 진공단열패널(6)의 모서리들을 눌러 고정하도록 이루어져 있다. 이에 따라 상기 진공단열패널(6)은 스터드 볼트(51)와 제1, 제2 고정부재(3)(4)를 포함한 장착부재가 상기 진공단열패널(6)의 모서리가 만나는 정점부분에서 수용된다. The vacuum insulating panel 6 of the lower vacuum insulating panel layer 6a having the corners laid on the pad 2 is fixed to the first fixing member 3 fixing the pad 2 to the second fixing member 4 Is screwed and fixed. The second fixing member 4 is composed of a plate-shaped pressing plate 72 and a lower end 71 provided below the pressing plate 72 so that the lower end 71 of the second fixing member 4 is fixed to the first fixing And the pressing plate 72 is pressed and fixed to the corners of the respective vacuum heat-insulating panels 6 when the pressing plate 72 is engaged with the member 3. The vacuum insulating panel 6 is accommodated at the apex portion where the stud bolt 51 and the mounting member including the first and second fixing members 3 and 4 meet at the edge of the vacuum insulating panel 6 .

한편, 상기 패드(2)의 중앙부에서 단차진 단차부위의 빈 공간(8)과 진공단열패널(6)의 인접된 진공단열패널(6) 간 사이는 탄성을 가지는 폼이나 무기질 섬유계로 구성되는 단열패드(5)가 채워진다. 상기 진공단열패널(6) 간 사이의 단열패드(5)는 진공단열패널(6) 측면에 미리 부착되어 장착될 수 있거나, 진공단열패널(6)이 장착된 후에 끼워져 장착될 수 있다. 상기 패드는 액화가스가 공급 혹은 배출됨에 따라 탱크 몸체(1)가 수축 혹은 팽창하는 것에 따라 그 폭이 변화할 수 있다. The space between the empty space 8 at the stepped portion at the center of the pad 2 and the adjacent vacuum insulation panel 6 of the vacuum insulation panel 6 is formed of a foam having elasticity or an inorganic fiber system The pad 5 is filled. The heat insulating pads 5 between the vacuum insulating panels 6 can be attached and attached in advance on the side surface of the vacuum insulating panel 6 or fitted after the vacuum insulating panel 6 is mounted. The width of the pad may vary as the tank body 1 shrinks or expands as the liquefied gas is supplied or discharged.

상기의 진공단열패널(6)은 하부 진공단열패널층(6a) 위에 상부 진공단열패널층(6b)이 복수 개의 층으로 적층될 때, 교차적층 하도록 구성한다. 도 3의 (a)와 같이 인접된 진공단열패널(6)들간에 적층방향의 경계면이 일직선 상으로 적층되면 대기로부터의 열이 탱크표면까지 도달하는 길이가 상대적으로 짧아 단열성능이 떨어진다. 반면, 도 3의 (b)에 도시된 본 발명의 바람직한 실시형태와 같이 진공단열패널(6)이 서로 연달아 교차적층되면, 적층방향의 경계면이 지그재그를 이루어 대기로부터의 열이 탱크표면까지 도달하는 길이가 길어 단열성능이 개선된다. 이는 아래의 수식과 같은 푸리에 법칙에 따라 근거한다.The vacuum thermal insulation panel 6 is configured to cross-laminate the upper vacuum insulation panel layer 6b on the lower vacuum insulation panel layer 6a when the upper vacuum insulation panel layer 6b is laminated into a plurality of layers. As shown in FIG. 3 (a), when the interface between the adjacent vacuum heat insulating panels 6 is stacked in a straight line, the length of heat from the atmosphere reaching the surface of the tank is relatively short. On the other hand, when the vacuum insulating panels 6 are sequentially stacked on each other as in the preferred embodiment of the present invention shown in FIG. 3 (b), the boundary surface in the stacking direction is staggered so that heat from the atmosphere reaches the tank surface The insulating performance is improved because the length is long. This is based on the Fourier's law as the following formula.

푸리에 법칙은 다음 수학식 1과 같다.The Fourier's law is expressed by the following equation (1).

[수학식 1] [Equation 1]

Q = -kA(t2-t1)/L Q = -kA (t2-t1) / L

(여기서 Q; 열전달량, A;단면적, k;열전도율, t2-t1;온도차, L;거리)(Where Q is the heat transfer coefficient, A is the cross-sectional area, k is the thermal conductivity, t2-t1 is the temperature difference,

상기 푸리에 법칙에 따르면, 전달되는 열량은 단면적에 비례하고, 온도구배에 대해 거리에 반비례한다. 즉, 진공단열패널(6)의 적층방향 경계면이 일직선 상으로 적층되어 시공하는 것보다 지그재그로 교차적층 시공할 경우, 대기로부터의 열이 탱크표면까지 도달하는 길이가 길어지기 때문에 열량을 최소화하여 단열성능을 개선할 수 있음을 알 수 있다.According to the Fourier's rule, the amount of heat transferred is proportional to the cross-sectional area and inversely proportional to the distance with respect to the temperature gradient. In other words, when cross-lamination is performed in a zigzag manner than in the case where the lamination directional interfaces of the vacuum insulation panels 6 are stacked in a straight line, the length of the heat from the atmosphere reaching the tank surface becomes longer, It can be seen that the performance can be improved.

상기 진공단열패널(6)은 적어도 하나 이상 연달아 적층되면, 도 4에 도시된 바와 같이 적어도 하나는 진공단열패널 상에 보호층(81)을 포함할 수 있다. 상기 보호층(81)은 상기 진공단열패널이 외부의 온도환경이나 압력, 기계적 충격으로부터의 내부 진공훼손을 보호한다.As shown in FIG. 4, at least one of the vacuum insulation panels 6 may include a protection layer 81 on a vacuum insulation panel. The protective layer 81 protects the vacuum insulation panel from internal vacuum damage from external temperature conditions, pressure, and mechanical impact.

도 4는 상기 보호층(81)이 포함된 진공단열패널이 맨 상부층에 적층된 경우를 예시하고 있다. 상기 보호층(81)은 진공단열패널 외부에 적층될 수 있으며, 진공단열패널 외면에 코팅될 수 있다. 상기 보호층(81)은 폴리프로필렌, 폴리에틸렌, 폴리스티렌, 폴리비닐알콜, 폴리카보네이트, 폴리메틸 메타크릴레이트, 폴리에틸렌테레프탈레이트와 같은 유기재질의 시트 또는 발포폼, 부직포, 유리섬유와 같은 무기재질의 시트로 형성할 수 있다.4 illustrates a case where a vacuum insulating panel including the protective layer 81 is laminated on the uppermost layer. The protective layer 81 may be laminated outside the vacuum insulation panel and coated on the outer surface of the vacuum insulation panel. The protective layer 81 may be formed of a sheet of an organic material such as polypropylene, polyethylene, polystyrene, polyvinyl alcohol, polycarbonate, polymethyl methacrylate, or polyethylene terephthalate or a sheet of inorganic material such as foam, .

The finishing material may be a composite sheet or rubber sheet of phenolic resin, epoxy resin, polyester resin or thermosetting resin reinforced with a sheet of metal such as galvalume, aluminum, zinc, or stainless steel, or fiber such as carbon fiber, Wood plate materials and the like can be used.

Accordingly, as shown in (b), the finish material 7 is bent at 90 degrees to be bolted horizontally, or an adhesive is applied between the finish material 7 and the vacuum insulation panel 6 as shown in (c) It is preferable to induce the fixing by the above-mentioned method, or optionally to finish the above-mentioned manner and fix it with a band as in (d).
