Abstract
A shipping liquid cargo tank of LNG transport ship comprises a liquid cargo tank body, a filler for cold insulation, an air chamber and a deep well pump base. The liquid cargo tank body is a tank body with a cylindrical middle part and two hemispherical ends and comprises an inner tank and an outer tank; the filler for cold insulation is filled between the inner tank and the outer tank; and vacuum-pumping treatment is carried out. The air chamber and the deep well pump base are respectively installed at the upper part of the liquid cargo tank body. The utility model changes the disadvantages of the traditional spherical independent liquid tank such as low capacity availability ratio and bad stability so that the tank is not easy to damage with the effect of navigation live load without LNG leakage safety and reliably.
Description
Technical field
The utility model relates to the ocean carrier that is loaded with liquid goods jar, particularly relates to the oceangoing ship fortune liquid goods jar of LNG cargo ship.
Background technique
In recent years, along with the process of industrial development and the construction in cities and towns, the natural gas consumption strong growth, data shows, needs import 900 billion cubic meters to the year two thousand twenty China's natural gas.A large amount of rock gas imports needs large-scale LNG Liquefied natural gas (LNG) ocean carrier to be transported to special-purpose LNG and receives harbour.As everyone knows, LNG Liquefied natural gas can be with the ship that has been equipped with the low temperature cargo hold, and its cargo hold form is spherical free-standing liquid tank or film type liquid tank.The volume of compartment utilization ratio of spherical free-standing liquid tank is low, and stability is poor; When the film type liquid tank navigated by water in stormy waves, the shell distortion had certain influence to internal tank insulation, was subject to mechanism and damaged, and the dynamic load impact of ship causes the damage in cabin easily.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of cargo hold utilization ratio height, the oceangoing ship of non-damageable LNG cargo ship fortune liquid goods jar under the effect of navigation dynamic load.
The technological scheme that adopts is:
The oceangoing ship fortune liquid goods jar of LNG cargo ship comprises liquid goods tank body, cold insulation filler, air chamber and deep-well pump seat.Described liquid goods tank body is that intermediate portion is that cylindrical, two ends are hemispheric tank body, and liquid goods tank body is formed by interior jar and outer jar, filling cold insulation filler between interior jar and outer jar, and vacuumize processing.Air chamber and deep-well pump seat are located at the top of liquid goods tank body respectively.
The upper end of above-mentioned liquid goods tank body is provided with the safety valve connecting base.
Above-mentioned cold insulation filler is expanded perlite or flexible glass fibre felt.
Above-mentioned liquid goods tank body lower end is provided with fixed saddle and sliding saddle, and the lower end of its fixed saddle and liquid goods tank body is fixed.
The volume of compartment utilization ratio that the utility model has changed traditional spherical free-standing liquid tank is low, the deficiency of stability difference, and not fragile under the effect of navigation dynamic load, LNG is non-leakage, and is safe and reliable.

Embodiment
The oceangoing ship fortune liquid goods jar of LNG cargo ship comprises liquid goods tank body 1, cold insulation filler 4, air chamber 6 and deep-well pump seat 7.Described liquid goods tank body 1 is that intermediate portion is that cylindrical, two ends are hemispheric tank body, and liquid goods tank body 1 is formed by interior jar 3 and outer jar 2, interior jar 3 and outside the perlitic cold insulation filler 4 of filling expansion between the jar 2, and vacuumize processing.Described liquid goods tank body 1 adopts low temperature resistant steel, can select nickel steel, Austenitic Stainless Steel, aluminum alloy for use, is preferably stainless steel.Air chamber 6 and deep-well pump seat 7 are located at the top of liquid goods tank body 1 respectively, safety valve connecting base 5 is established in liquid goods tank body 1 upper end, liquid goods tank body 1 lower end is provided with fixed saddle 8 and sliding saddle 9, and its fixed saddle 8 is fixed with the lower end of liquid goods tank body 1, constitutes the oceangoing ship fortune liquid goods jar of LNG cargo ship.One end of liquid goods tank body 1 is fixedly fastened on the bottom of ship by fixed saddle 8, and the other end supports by sliding saddle 9, can make tank body in the tolerance zone of operating pressure and operating temperature, along ground free expansion of hull bottom planar radial or contraction.The also supported or suspension of the free end of liquid goods tank body makes that tank body can the occurred level displacement when boats and ships moved.Liquid goods tank body design pressure is 6～8 crust, and operating temperature is-165 ℃.
