Description

Fluid tank including an internal pressure booster
Technical Field
The present invention relates to a fluid tank including an internal pressurizer, and more particularly, to a fluid tank including an internal pressurizer, which can store a liquid fluid such as liquefied natural gas, and can heat a part of the liquid fluid to generate an evaporation gas and deliver the liquid fluid to the outside by pressurization caused by the evaporation gas.
Background
Fig. 1 is a diagram illustrating a conventional fluid tank 10.
The conventional fluid tank 10 includes a tank body 1 that can store liquid fluid such as liquefied natural gas. At this time, in order to transport the liquid fluid stored inside the tank body 1 to the outside, the liquid fluid is transported to the outside through the transport pipe 5 by pressurizing the inside of the tank body 1.
A conventional fluid tank 10 is provided with a pressurizing unit 3 of an evaporator or the like provided outside a tank body 1, a liquid fluid is supplied to the pressurizing unit 3 through a lower pipe 2 connecting the tank body 1 and the pressurizing unit 3, the pressurizing unit 3 vaporizes the liquid fluid by an operation of the evaporator or the like to form a vaporized gas, and supplies it to the tank body 1 through an upper pipe 4, thereby pressurizing the inside of the tank body 1.
That is, a part of the liquid fluid stored inside the tank main body 1 is supplied to the pressurizing unit 3, and the inside of the tank main body 1 is pressurized by the evaporation gas generated by the operation of the pressurizing unit 3, thereby delivering the liquid fluid to the outside.
At this time, since the conventional fluid tank 10 needs to supply the liquid-like fluid to the pressurizing unit 3, in order to smoothly supply the liquid-like fluid, the lower pipe 2 is connected at the lower portion of the tank body 1 and supplies the liquid-like fluid to the pressurizing unit 3 therethrough. However, the above arrangement has a risk of fluid leakage at a portion where the lower portion of the tank main body 1 is connected to the lower pipe 2.
If the liquid fluid stored in the fluid tank 10 is liquefied natural gas at an ultra-low temperature, there is a risk of explosion due to brittleness at the ultra-low temperature, fire, and the like, and thus there is a risk of a user safety accident.
Further, since the pressurizing unit 3 is provided outside the tank body 1 and the liquid or gas-like fluid is flowed by connecting the lower pipe 2 and the upper pipe 4, etc., a space for providing the pressurizing unit 3 outside is additionally required, and a control valve for controlling the fluid flowing around the pressurizing unit 3 is additionally provided, which causes a problem that the manufacturing cost and the manufacturing time of the fluid tank 10 are increased.

Detailed Description
The fluid tank including the internal pressure booster according to the present invention as described above will be described in detail hereinafter with reference to the accompanying drawings.
< first embodiment >
Fig. 2 is a diagram showing a fluid tank including an internal supercharger according to a first embodiment of the present invention, and fig. 3 is another diagram showing a fluid tank including an internal supercharger according to a first embodiment of the present invention.
Referring to fig. 2 and 3, a fluid tank 1000 including an internal pressurizer according to a first embodiment of the present invention includes a tank body 100 storing and accommodating a liquid fluid, and is formed to be able to transport the liquid fluid stored inside to the outside (a fluid demand point, etc.) by pressurization inside the tank body 100.
At this time, the liquid fluid for storage and transportation in the fluid tank 1000 including the internal pressurizer according to the first embodiment of the present invention is Liquefied Natural Gas (LNG), and in addition to the LNG, as long as it can be stored inside the tank body 100 and transported to the outside by pressurization, embodiments of a plurality of liquid fluids such as liquefied hydrogen gas are also possible.
The fluid tank 1000 including the internal pressurizer according to the first embodiment of the present invention includes a tank main body 100 storing a liquid fluid such as liquefied natural gas, a pressurization pipe 200 provided at each part of the tank main body 100 and formed to be able to accommodate a part of the liquid fluid, a pressurization unit 300 provided inside the pressurization pipe 200 and configured to be able to heat the liquid fluid to pressurize the inside of the tank main body 100, and a delivery pipe 400 formed to be able to deliver the liquid fluid to the outside by pressurizing the tank main body 100 by the pressurization unit 300.
That is, in the fluid tank 1000 including the internal pressurizer according to the first embodiment of the present invention, the pressurizing unit 300 heats the liquid-like fluid contained inside the pressurizing pipe 200 to form the evaporation gas, and pressurizes the inside of the tank main body 100 by the formation of the evaporation gas, so the liquid-like fluid stored inside the fluid tank 100 can be delivered to the outside through the delivery pipe 400 by the pressure thereof.
More specifically, the tank body 100 may be a general tank for storing a liquid fluid, a vehicle fuel tank, a ship fuel tank, a tank truck, or other multi-purpose tanks.
The pressure increasing duct 200 is formed in a shape penetrating in the up-down direction at a selected position inside the tank body 100. The pressurization pipe 200 is formed in a hollow shape in the vertical direction, and thus can accommodate a part of the liquid fluid stored inside the tank body 100 and can be pressurized by the pressurization unit 300.
The pressurizing unit 300 is positioned in the hollow of the pressurizing duct 200 and heats the liquid-like fluid contained inside the pressurizing duct 200 to form the evaporation gas, thus being capable of pressurizing the inside of the tank body 100.
The pressurizing unit 300 may be configured as various units for heating the liquid-like fluid contained inside the pressurizing duct 200, and may be configured of a unit that can heat the liquid-like fluid contained inside the pressurizing duct 200 by the supply of electric energy to form the evaporation gas, as an example.
As another example of the pressurizing unit 300, an embodiment is possible in which the pressurizing unit is configured by a unit that heats a liquid fluid by exchanging heat with the liquid fluid inside the tank main body 100 using a gas-like heating medium, a liquid-like heating medium, or the like, and a plurality of pressurizing units that form an evaporation gas and pressurize the inside of the tank main body 100 by the evaporation gas to convey the liquid fluid or the like stored inside the tank main body 100.
At this time, the pressurizing pipe 200 heats the liquid fluid contained in the hollow inside by the pressurizing unit 300 to pressurize the tank main body 100, and therefore, it is preferable that it is formed of a heat insulating material or formed by a heat insulating treatment to improve the heating efficiency of the liquid fluid.
Meanwhile, the pressurization duct 200 is formed such that the selected lower side is positioned on the liquid fluid and the liquid fluid flows in from the lower portion so as to be able to be heated, and the evaporation gas formed by the pressurization unit 300 needs to be supplied to the gaseous fluid inside the tank main body 100, whereby the pressurization of the tank main body 100 is efficient, and therefore, preferably, the selected upper side is formed to be positioned at the upper side than the liquid fluid.
The delivery pipe 400 is provided with an inlet to allow the liquid fluid to flow into a lower side of the inside of the tank body 100, and is formed to be able to deliver the liquid fluid stored in the tank body 100 to the outside.
Preferably, in the delivery pipe 400, an inlet through which the liquid fluid flows in and flows is positioned at the bottom surface inside the tank body 100 so as to be able to deliver the liquid fluid to the outside even in a case where the flow rate of the liquid fluid is small.
As described above, the fluid tank 1000 including the internal pressurizer according to the first embodiment of the present invention can transport the liquid fluid contained in the tank main body 100 to the outside by heating the liquid fluid by the pressurizing unit 300 and pressurizing the inside of the tank main body 100 by the evaporation gas generated by the heating, and thus has an advantage in that the liquid fluid can be safely stored and transported as compared with the conventional art in which the evaporator is provided to the outside and the tank main body is pressurized by the operation of the evaporator.
That is, the fluid tank 1000 including the internal pressurizer according to the first embodiment of the present invention is advantageous in that it heats the liquid fluid inside the tank body 100 without movement of the fluid stored inside, thereby reducing leakage of the liquid fluid, because the fluid inside the tank body needs to be supplied to the evaporator, and thus, most of the fluid is positioned at the lower portion of the tank body, and there is a risk of outflow of the fluid in the tank body due to this, and there is a problem of exposure to a fire hazard or an explosion hazard.
Further, since the fluid tank 1000 including the internal pressurizer according to the first embodiment of the present invention does not need to be provided with an additional pipe, a valve for controlling the fluid moved through the pipe, and the like according to the arrangement of the external evaporator, the manufacturing cost and the manufacturing time of the fluid tank 1000 can be reduced.
Meanwhile, the fluid tank 1000 including the internal pressurizer according to the first embodiment of the present invention is advantageous in that it can shorten the time for heating the fluid to form the boil-off gas by heating the liquid fluid contained in the pressurizing pipe 200 to pressurize the inside of the tank main body 100, instead of heating the entire liquid fluid contained in the tank main body 100.
Meanwhile, referring to fig. 3, it is preferable that the pressurization duct 200 is formed at a right angle in the vertical direction and accommodates the liquid fluid therein to improve accuracy for heating the liquid fluid, but various shapes of embodiments are possible as long as the liquid fluid can be introduced from the lower portion and accommodated and the evaporation gas formed by heating can be discharged to the upper portion to pressurize the inside of the can body 100, depending on the shape or position of the heating unit 300 or the shape or purpose of the can body 100.
< second embodiment >
Fig. 4 is a diagram showing a fluid tank including an internal pressure booster according to a second embodiment of the present invention.
Referring to fig. 4, the tank body 100 of the fluid tank 1000 including the internal supercharger according to the second embodiment of the present invention may further include a residual fluid portion 110 protruding in a lower direction corresponding to a position where the supercharger pipe 200 is formed, thereby forming a groove.
Further, the booster duct 200 is formed to extend toward the remaining fluid portion 110 so as to be able to accommodate therein the liquid fluid accommodated in the remaining fluid portion 110.
That is, in the case where the amount of the liquid-like fluid contained inside the tank body 100 is not large, it is difficult to contain inside the pressure increasing duct 200, and it is difficult to heat the inside of the pressure increasing duct 200, and therefore it may be difficult to pressurize the inside of the tank body 100.
For this reason, the fluid tank 1000 according to the second embodiment of the present invention includes the residual fluid amount part 110 in the tank main body 100 and preferentially stores the liquid fluid stored inside the tank main body 100, so that the liquid fluid inside the pressure increasing pipe 200 can be easily heated.
Meanwhile, it is preferable that although the residual fluid portion 110 needs to accommodate as much flow rate of the liquid fluid as possible, since the booster duct 200 needs to be elongated and positioned, it needs to be formed at least larger than the diameter of the booster duct 200.
