A little attached drawings obtain other attached drawings.
Fig. 1 show the principle schematic diagram of LNG storage tank in the specific embodiment of the invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out detailed retouch
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained without making creative work
Example, shall fall within the protection scope of the present invention.
Join shown in Fig. 1, the LNG storage tank in the present embodiment, including horizontal tank tank body 1, passes through heat-flash on the inner wall of tank body 1
Conductor and inner wall form conducting space 2, and 1 wall of tank body is equipped with the first conduction hole 3 and second and conducts hole 4, the first conduction hole 3 and the
Two conduction holes 4 are connect with the first actuating unit 5 and the second actuating unit 6 respectively, the first actuating unit 5 and the second actuating unit 6

Mechanism 5 and the second actuating unit 6 are all connected with PLC.
Further, strong conductor is glass.
Further, actuating unit is pump.
Further, conducting space 2 is arc.
Further, cooling device 8 is equipped in babinet 7.
Further, strong heat conducting medium is water.
Further, hole 4 is conducted in the first conduction hole 3 on horizontal position less than second.
In the technical scheme, LNG storage tank is followed using the strong feature of heat conducting medium conductivity of heat by what is be arranged in tank body
Ring endothermic system controls the temperature of LNG, to stablizing pressure of the LNG in tube body, prevents LNG from generating rollover phenomenon to tank body
Mechanical damage is generated, economic loss and environmental pollution are brought.
It is as follows that principle is embodied：
First, tank body temperature is transferred to by thermometer on PLC, when numerical value of the temperature higher than setting, the first driver
Strong heat conducting medium in babinet 7 is transferred in arc conducting space 2 by structure 5, absorbs the temperature of tank body then in the second engine
It is transferred in babinet from the second conduction hole 4 under the action of structure 6, in the process, the cooling device in babinet 7 is operating always,
It is in lower state to which the heat-flash in guard box body leads medium temperature, such circulation heat absorption is until tank body temperature is reduced to
Relatively low numerical value avoids LNG from generating rollover phenomenon and generates mechanical damage to tank body.
