As shown in fig. 2 and 3, the present embodiment provides a low-temperature cargo leakage protection device 4 for an independent liquid tank 2, which comprises a liquid collecting part 410 fixed on the side of the liquid tank 2 and a liquid containing part 420 fixed on the side of a ship body 1, wherein the liquid collecting part 410 and the liquid containing part 420 are arranged in a spaced manner and vertically corresponding to each other; the liquid collecting portion 410 is provided with a liquid outlet 414, the liquid containing portion 420 is provided with a liquid inlet 416, the liquid outlet 414 and the liquid inlet 416 are correspondingly arranged up and down, and the size of the liquid inlet 416 is larger than that of the liquid outlet 414.
The liquid collecting part 410 covers the liquid tank leakage hidden danger points 210 (such as the structural surface of welding seams of the liquid tank 2), when the liquid tank 2 leakage hidden danger points 210 leak, low-temperature liquid cargo firstly flows into the liquid collecting part 410, so that the leaked low-temperature liquid cargo is not splashed or flows outwards, but flows out through the liquid outlet 414 of the liquid collecting part 410, and then flows into the liquid containing part 420 through the liquid inlet 416 which vertically corresponds to the liquid outlet 414, the leaked liquid cargo is prevented from directly flowing into the ship body 1, so that the ship body 1 is fragile and damaged, therefore, the structure of the ship body 1 can adopt a common steel plate instead of a low-temperature special steel plate, and the economy is improved. The size of the liquid inlet 416 is larger than that of the liquid outlet 414, on one hand, it is ensured that the leakage liquid flowing out of the liquid outlet 414 can flow into the liquid containing part 420 by 100%, so that the liquid containing part 420 can receive all leakage cold goods flowing out of the liquid collecting part 410, on the other hand, when the liquid tank 2 leaks, substances in the liquid containing part 420 are gasified due to the fact that the ambient temperature in the liquid containing part 420 is high, the gasified substances can be volatilized as much as possible through the large-size liquid inlet 416, and the liquid containing capacity of the liquid containing part 420 is further improved.
The material used to form the liquid collecting part 410 and the liquid containing part 420 is generally steel. The liquid collecting part 410 and the liquid containing part 420 are arranged in a spaced mode, namely, the liquid collecting part 410 and the liquid containing part 420 are not in direct contact, so that direct heat exchange between the cabin body and the ship body 1 through steel materials with large heat conductivity coefficients is avoided, and heat circulation between the liquid collecting part 410 and the liquid containing part 420 is greatly reduced. Further, the low-temperature liquid in the liquid tank 2 (minus 50 ℃ C. or lower) is not damaged by the low-temperature brittleness of the liquid containing portion 420 due to the low temperature of the liquid containing portion 420 caused by the heat conduction of the steel material. This makes the material for making liquid containing portion 420 wider in the selection, for example liquid containing portion 420 can use conventional low temperature steel D and above, can satisfy the security requirement, the cost is reduced. Meanwhile, the heat of the outboard seawater with relatively high temperature (0 ℃ and above) at the side of the ship body 1 is less transferred to the liquid tank 2, so that the influence of the ambient temperature on the evaporation rate of the low-temperature liquid tank 2 is reduced, and the technical index is improved. Preferably, dry inert gas is filled between the liquid collecting part 410 and the liquid containing part 420, so that heat exchange between the liquid tank 2 and the hull 1 can be better reduced, and simultaneously, a non-combustible environment is provided, and the possibility of inflammable gas mixture existing in the hull cabin is eliminated.
As shown in fig. 3, the sump portion 410 includes a sump surrounding plate 412, a sump panel 413 and a sump cavity 417; the liquid collecting coaming 412 is fixedly connected to the liquid tank 2, the liquid collecting coaming 412 extends downwards from the liquid tank 2, and the lower end of the liquid collecting coaming 412 is fixedly connected with the liquid collecting panel 413; the liquid collecting surrounding plate 412, the liquid cabin 2 and the liquid collecting panel 413 surround a liquid collecting cavity 417; the liquid outlet 414 penetrates the liquid collection panel 413 and communicates with the liquid collection chamber 417. Wherein the drip dam 412 is positioned around a tank leak and the drip chamber 417 is adapted to receive spilled or out-flowing cold cargo. The liquid collecting part 410 is simple in structure and simple and convenient in manufacturing process, and the connection between the liquid collecting coaming 412 and the liquid cabin 2 and the connection between the liquid collecting coaming 412 and the liquid collecting panel 413 can be achieved in a welding mode.
As shown in fig. 3, a liquid collecting shim plate 411 is fixedly connected between the liquid collecting coaming 412 and the liquid tank 2 so as to firmly connect the liquid collecting part 410 and the liquid tank 2. The liquid collecting backing plate 411 is connected with the liquid tank 2 in a peripheral welding mode, and the liquid collecting coaming plate 412 is connected with the liquid collecting backing plate 411 and the liquid collecting panel 413 in a fillet welding mode. The liquid collecting base plate 411 mainly has the effects of locally thickening and reinforcing, increasing the stress area between the liquid collecting enclosing plate 412 and the liquid tank 2, and avoiding the direct welding of the liquid collecting enclosing plate 412 to the surface of the liquid tank 2 so as to increase the local stress of the liquid tank 2.
Preferably, as shown in FIG. 3, the drip pan 413 is inclined in a downward manner as it approaches the liquid outlet 414, mainly considering that the leaked liquid flows into the liquid outlet 414 along the drip pan 413 under gravity, avoiding the liquid accumulation that may exist in the drip portion 410.
Further, as shown in fig. 3, a tank thermal insulation 3 is fixedly arranged on the liquid collecting panel 413 and the outer periphery side of the tank 2, and the liquid collecting panel 413 is hermetically connected with the tank thermal insulation 3. The liquid tank thermal insulation 3 can be a prefabricated polystyrene insulation board EPS or a foamed polyurethane PU. In the long-term operation process of the ship, a gap may appear between the liquid tank thermal insulation 3 and the liquid collecting coaming 412 under the action of stress, and a sealing tape 415, such as a butyl tape, may be additionally arranged at the joint of the liquid tank thermal insulation 3 and the liquid collecting panel 413 to increase the sealing property.
Further, as shown in fig. 3, the liquid containing part 420 includes a liquid containing panel 421, a liquid containing coaming 422, a liquid containing bottom plate 423 and a liquid containing cavity 425; the liquid containing bottom plate 423 is fixedly connected with the ship body 1, the lower end of the liquid containing coaming 422 is fixedly connected with the liquid containing bottom plate 423, the liquid containing coaming 422 extends upwards from the side of the ship body 1, and the upper end of the liquid containing coaming 422 is fixedly connected with the liquid containing panel 421; the liquid containing panel 421, the liquid containing coaming 422 and the liquid containing bottom plate 423 form a liquid containing cavity 425; the liquid outlet 414 penetrates the liquid containing panel 421 and is communicated with the liquid containing cavity 425. The liquid containing cavity 425 is used for containing liquid, the liquid containing panel 421, the liquid containing coaming 422, the liquid containing bottom plate 423, the liquid tank 2 and the ship body 1 are connected in a welding mode, and the structure and the manufacturing process of the liquid containing part 420 are simpler.
Preferably, as shown in FIG. 3, the liquid containing panel 421 is inclined in such a manner that it is more upward closer to the liquid inlet 416. The structure and equipment code (IGC rule) of an international bulk transport liquefied gas ship, issued by the International Maritime Organization (IMO) Maritime Safety Committee (MSC), clearly stipulates that the safety requirement of the static trim 30 ° attitude of the ship is to be met. The inclined arrangement of the liquid containing panel 421 can meet the requirement that liquid cargo in the liquid containing part 420 is still in the liquid containing cavity 425 without leakage when the ship statically tilts for 30 degrees.
Further, as shown in fig. 3, the liquid containing surrounding plate 422 and the liquid containing bottom plate 423 are both fixedly provided with a thermal insulation wall 424 on the inner wall. The inner walls of the liquid containing coaming 422 and the liquid containing bottom plate 423 are provided with heat insulation walls 424, the heat insulation walls 424 can be prefabricated heat insulation boards of certain thickness, polystyrene or foaming polyurethane, the effect of the heat insulation walls is heat insulation, and the heat transfer of the leaked low-temperature liquid cargo is reduced to the structural steel plate of the ship body 1, so that the low-temperature brittleness is damaged.
As shown in fig. 3 and 4, a plurality of small base plates 430 arranged at intervals are fixedly arranged under the liquid containing bottom plate 423, and the liquid containing bottom plate 423 is fixedly connected with the hull 1 through the plurality of small base plates 430. The small base plate 430 comprises a bottom small base plate 432 and a bottom triangular base plate 431, and the liquid containing base plate 423 is connected with the ship body 1 through the bottom small base plate 432 and the bottom triangular base plate 431, but is not in direct contact with a large area. Because the liquid containing bottom plate 423 on the ship body 1 is a main heat conducting medium, the application of the small base plate 430 can greatly reduce the contact surface between the liquid containing bottom plate 423 and the ship body 1, namely, the heat transfer path is reduced, and the structural temperature of the ship body 1 is protected from being reduced to an ultralow temperature state to generate brittle failure.
A bottom support toggle plate 433 is welded between the liquid containing enclosing plate 422 and the bottom triangular base plate 431, and a circular toggle plate welding process notch 434 is arranged at the bottom end of the bottom support toggle plate 433. This has mainly played the effect that the structure is strengthened and is supported, and the protection holds liquid bounding wall 422 and can not appear big structural deformation.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
