Description

[0001] The present invention relates to a structure for fuel storage tanks,

The present invention relates to a fuel storage tank structure.

In ships such as large container ships, HFO (Heavy Fuel Oil), which has high viscosity at room temperature like Bunker C oil, is used as the fuel flow of the main engine. In this case, the HFO has low fluidity due to its high viscosity characteristics and is difficult to supply from the fuel storage tank to the main engine. Therefore, in order to increase the fluidity of the HFO before supplying it to the main engine, a method of lowering the viscosity of the HFO by heating the entire fuel storage tank in which the HFO is stored is used.

However, such a method has a disadvantage in that energy is wasted due to heat loss or the like generated on the surface of the fuel storage tank. To overcome this disadvantage, a fuel supply system for heating fuel oil in a small capacity tank outside the fuel storage tank is being developed.

This fuel supply system introduces a high-temperature HFO heated in a small-capacity settling tank or service tank into a small area inside a large-capacity fuel storage tank, and a high-temperature HFO introduced into the small- The process of supplying the HFO to the settling tank or the like is repeated, and the heated HFO is supplied to the main engine in the repeating process.

On the other hand, the moving path of the high temperature HFO flowing from the outside of the fuel storage tank to the small area and the moving path of the HFO supplied to the settling tank in the small area can use one pipe installed in the fuel storage tank. At this time, the high-temperature HFO flowing into the small region is low in density and can rise straight up to the upper portion of the small region, and can gather and stagnate at the upper portion.

In this case, there is a problem that the high-temperature HFO and the low-temperature HFO are not effectively mixed in the small region. Further, there is a problem that the low-temperature HFO stays at one end of the pipeline into which the HFO is introduced or supplied, and the low-temperature HFO is supplied to the settling tank, thereby lowering the heating efficiency of the HFO.

An embodiment of the present invention is to provide a fuel storage tank structure in which hot fuel oil and low-temperature fuel oil are effectively mixed.

According to an aspect of the present invention, there is provided a fuel storage apparatus comprising: a fuel storage tank for storing fuel oil; A partitioning member partitioning the fuel storage tank into a first region and a second region communicating with each other; Temperature fuel oil heated at the outside of the fuel storage tank flows into the first region, or a medium-temperature fuel oil in which the high-temperature fuel oil and the low-temperature fuel oil accommodated in the first region are mixed is stored in the first region, Wherein the first region is in communication with the fuel moving pipe and communicates with the fuel moving pipe in a high temperature region in which the high temperature fuel oil is accommodated, A low temperature region where the low temperature fuel oil is accommodated, can be provided.

Temperature fuel oil flowing into the one end of the fuel moving pipe in the high-temperature region and the one end of the fuel moving pipe in the low-temperature region when the medium-temperature fuel oil is discharged to the outside of the fuel storage tank through the fuel moving pipe The inflow amount of the inflowing low-temperature fuel oil may be the same.

Temperature zone is connected to one end of the fuel moving pipe by a first moving passage, the low-temperature zone is connected to one end of the fuel moving pipe by a second moving passage, and the side wall of the high- At least one first communication hole communicating with the outside is formed, and at least one second communication hole communicating between the inside and the outside of the low-temperature region may be formed on the side wall of the low-temperature region.

The first moving passage may be provided longer than the second moving passage, and the total cross-sectional area of the first communicating hole may be larger than the total cross-sectional area of the second communicating hole.

The first region may form a region smaller than the second region.

According to the embodiment of the present invention, when the fuel oil is discharged out of the fuel storage tank in the small area, the high-temperature fuel oil and the low-temperature fuel oil flow into the one end of the fuel transfer pipe in an equal amount so that the hot fuel oil and the low- The effect of discharging the medium temperature fuel oil mixed with the high temperature fuel oil and the low temperature fuel oil through the fuel transfer pipe can be improved.

It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, do. In the following description, terms such as first and second terms are used to describe various components, and the meaning is not limited to itself, and is used only for the purpose of distinguishing one component from another component do.

FIG. 1 is a view showing a fuel storage tank structure according to an embodiment of the present invention. FIG. 2 is a view showing a state where hot fuel oil is introduced into the first region of FIG. 1, Temperature fuel oil and low-temperature fuel oil are discharged from the engine.

1 to 3, a fuel storage tank structure 1000 according to an embodiment of the present invention includes a fuel storage tank 1100, a partition member 1300, and a fuel transfer pipe 1500.

The fuel storage tank 1100 stores fuel oil. Here, the fuel oil may be an HFO having a high viscosity such as Bunker C oil.

For example, the fuel storage tank 1100 may store the fuel oil required for the main engine (not shown) of the ship during the period when the ship (not shown) is navigating.

The partition member 1300 divides the interior of the fuel storage tank 1100 into a first region 1100a and a second region 1100b.

The first region 1100a defined by the partition member 1300 can form a region smaller than the second region 1100b. In other words, the first area 1100a may be a small area as compared with the second area 1100b.

The partition member 1300 may be composed of at least one plate.

For example, the partition member 1300 may be a combination of a plurality of plates as shown in FIG. In this case, the partition member 1300 may form a sidewall surrounding the first region 1100a, which is a small region below the fuel storage tank 1100, together with a part of the side wall of the fuel storage tank 1100. [

The first region 1100a and the second region 1100b can communicate with each other. In this case, the fuel oil stored in the fuel storage tank 1100 can move between the first region 1100a and the second region 1100b.

In this embodiment, the first region 1100a may include a high temperature region 1110 and a low temperature region 1130. [

The high temperature fuel oil H which is heated outside the fuel storage tank 1100 and flows into the first region 1100a through the fuel moving pipe 1500 described later can be accommodated in the high temperature region 1110. [ In the low temperature region 1130, fuel oil pre-stored in the fuel storage tank 1100 can be accommodated. At this time, the fuel oil in the fuel storage tank 1100 accommodated in the low temperature region 1130 may be the low temperature fuel oil L which is low in temperature as compared with the high temperature fuel oil H.

2, the first region 1100a is divided into a high temperature region 1110 and a low temperature region 1110 by a separating member 1150 disposed in a horizontal direction inside a partition member 1300 surrounding the first region 1100a, Area 1130. In this embodiment, In this case, the separating member 1150 can be supported by the inner side of the partition member 1300. At this time, the high temperature region 1110 may be disposed on the upper side with respect to the low temperature region 1130.

In addition, the high temperature region 1110 and the low temperature region 1130 may be partitioned into various structures within the first region 1100a.

The fuel moving pipe 1500 is connected to the fuel tank 1100 so that the hot fuel oil H heated outside the fuel storage tank 1100 flows into the first region 1100a or the hot fuel oil H and the low temperature Temperature fuel oil mixed with the fuel oil L is discharged to the outside of the fuel storage tank 1100.

In other words, when it is necessary to heat the fuel oil in the first region 1100a, the high-temperature fuel oil H is supplied to the high-temperature region 1110a of the first region 1100a through the fuel- ). ≪ / RTI >

When the supply of fuel oil to the main engine is required, the high temperature fuel oil H contained in the high temperature region 1110 of the first region 1100a and the low temperature fuel oil H contained in the low temperature region 1130 of the first region 1100a (L) may be introduced into one end of the fuel transfer pipe 1500 as shown in FIG. At this time, the high temperature fuel oil H and the low temperature fuel oil L are mixed with each other by heat exchange, become medium temperature fuel oil, and the medium temperature fuel oil can be discharged to the outside of the fuel storage tank 1100 through the fuel transfer pipe 1500.

Temperature fuel oil flowing into the one end of the fuel transfer pipe 1500 in the high temperature region 1110 when the middle-temperature recirculating fluid is discharged from the fuel storage tank 1100 through the fuel transfer pipe 1500, H and the inflow amount of the low temperature fuel oil L flowing into the one end of the fuel moving pipe 1500 in the low temperature region 1130 may be the same. In this case, the high temperature fuel oil H and the low temperature fuel oil L can be effectively mixed. This will be described later.

On the other hand, the medium-temperature fuel oil has a lower viscosity than the low-temperature fuel oil (L), and thus the fluidity can be improved. This medium temperature fuel oil can be easily discharged from the fuel storage tank 1100 by moving through the fuel transfer pipe 1500. In this case, the discharged mesophilic fuel oil may be supplied directly to the main engine, or may be externally heated in the fuel storage tank 1100, and then supplied to the main engine or supplied to the fuel storage tank 1100 again.

At least a part of the fuel transfer pipe 1500 may extend vertically as shown in FIG. 1, but is not limited thereto.

One end of the fuel transfer pipe 1500 may be disposed in the first region 1100a.

In this embodiment, the high temperature region 1110 can communicate with the fuel transfer pipe 1500.

At this time, the high temperature region 1110 may be connected to one end of the fuel transfer pipe 1500 through the first transfer passage 1111.

In this case, the first moving passage 1111 is provided in the process of being accommodated in the hot zone 1110 at one end of the fuel moving pipe 1500, or in the process of being accommodated in the hot zone 1110 The flow of the high temperature fuel oil H can be guided in the process of flowing into the one end of the fuel transfer pipe 1500.

For example, the first transfer passage 1111 may be formed between the guide plate 1112 and the outer surface of the fuel transfer pipe 1500, which are spaced apart from the outer surface of the fuel transfer pipe 1500, as shown in FIG. In this case, the guide plate 1112 extends in the extending direction of the fuel transfer pipe 1500, and one side can be supported by the separating member 1150.

At this time, an extension portion 1112a extending toward the center line C of the fuel transfer pipe 1500 may be formed at one end of the guide plate 1112 near one end of the fuel transfer pipe 1500. The extension portion 1112a may cover a part of the lower portion of one end of the fuel transfer pipe 1500 as shown in FIG.

In this case, the hot fuel oil H which flows into the first region 1100a and flows upward flows efficiently through the first moving passage 1111 and into the high-temperature region 1110 disposed above the first region 1100a Can be moved.

Needless to say, the first moving passage 1111 may be formed in various structures to guide the movement of the hot fuel oil H.

In this embodiment, at least one first communication hole 1115 communicating with the inside and the outside of the high temperature region 1110 may be formed on the sidewall of the high temperature region 1110. At this time, the high temperature region 1110 can communicate with the second region 1100b.

For example, the first communication hole 1115 may be disposed under the high temperature region 1110 as shown in FIG. 2, but is not limited thereto.

In this embodiment, the low temperature region 1130 can communicate with the fuel transfer pipe 1500

At this time, the low temperature region 1130 may be connected to one end of the fuel transfer pipe 1500 through the second transfer passage 1131.

In this case, the second moving passage 1131 moves the low temperature fuel oil L in the process of flowing the low temperature fuel oil L into the one end of the fuel moving pipe 1500 in the low temperature region 1130, .

For example, the second moving passage 1131 may be formed between the extended portion 1112a formed at one end of the guide plate 1112 and the bottom of the low temperature region 1130, as shown in FIG.

Needless to say, the second moving passage 1131 can be formed in various structures that can guide the movement of the low-temperature fuel oil L. [

In this embodiment, at least one second communication hole 1135 communicating with the inside and the outside of the low temperature region 1130 may be formed on the sidewall of the low temperature region 1130. At this time, the low temperature region 1130 can communicate with the second region 1100b.

For example, the second communication hole 1135 may be disposed below the low temperature region 1130 as shown in FIG. In this case, the second communication hole 1135 may be located on the lower side corresponding to the position of the first communication hole 1115.

At this time, the second communication hole 1135 may be formed close to the bottom of the low temperature region 1130. In other words, the second communication hole 1135 may be formed close to the bottom of the first region 1100a.

In this case, even if the liquid level of the fuel oil stored in the second region 1100b is lower than the height of the partition member 1300, the fuel oil in the second region 1100b easily moves to the low temperature region 1130 And may be discharged outside the fuel storage tank 1100 through the fuel transfer pipe 1500. Therefore, the fuel oil stored in the fuel storage tank 1100 can not be discharged to the outside of the fuel storage tank 1100 and is not consumed, and can be prevented from being left in the fuel storage tank 1100.

Temperature fuel oil flowing into the one end of the fuel transfer pipe 1500 in the high temperature region 1110 when the medium temperature fuel oil is discharged through the fuel transfer pipe 1500 to the outside of the fuel storage tank 1100, H and the inflow amount of the low temperature fuel oil L flowing into the one end of the fuel moving pipe 1500 in the low temperature region 1130 may be the same.

For example, the first moving passage 1111 may be provided longer than the second moving passage 1131, and the total cross-sectional area of the first communication hole 1115 may be larger than the total cross-sectional area of the second communication hole 1135. [

When the first transfer passage 1111 is provided longer than the second transfer passage 1131, the flow resistance added to the hot fuel oil H passing through the first transfer passage 1111 is larger than the flow resistance added to the second transfer passage 1131 May be larger than the flow resistance added to the low-temperature fuel oil L passing therethrough. In this case, there may be a difference between the inflow amount of the high temperature fuel oil H and the inflow amount of the low temperature fuel oil L.

When the total cross-sectional area of the first communication hole 1115 is greater than the total cross-sectional area of the second communication hole 1135, the high-temperature fuel oil H passing through the first communication passage 1111 flows into the second communication passage 1131, The fluidity can be improved more than the low-temperature fuel passing through. In this case, the difference between the inflow amount of the hot fuel oil H and the inflow amount of the low temperature fuel oil L due to the difference in length between the first transfer passage 1111 and the second transfer passage 1131 can be eliminated.

More specifically, in the process of discharging the medium-temperature fuel oil through the fuel transfer pipe to the outside of the fuel storage tank 1100, the fuel flowing into the high temperature region 1110 through the first communication hole 1115 outside the high temperature region 1110 The amount of the oil may be greater than the amount of fuel oil flowing into the low temperature region 1130 through the second communication hole 1135 outside the low temperature region 1130. [

In this case, the fuel oil that flows in more through the first communication hole 1115 is heated by the high-temperature fuel oil H to overcome the flow resistance by the first moving passage 1111 and to quickly move the first moving passage 1111 And can be smoothly passed through. In this process, the inflow amount of the hot fuel oil H may be introduced into one end of the fuel moving pipe 1500 in the same manner as the inflow amount of the low temperature fuel oil L.

In addition, it goes without saying that various methods for allowing the hot fuel oil H and the low-temperature fuel oil L to flow into one end of the fuel transfer pipe 1500 in the same amount are also possible.

When the total cross-sectional area of the first communication hole 1115 is larger than the total cross-sectional area of the second communication hole 1135, the total cross-sectional area of the first communication hole 1115 is larger than that of the first communication hole 1115 The size of the second communication hole 1135 may be larger than the total cross-sectional area of the second communication hole 1135. The total number of the first communication holes 1115 may be greater than the number of the second communication holes 1135 so that the total cross sectional area of the first communication holes 1115 is larger than the total cross sectional area of the second communication holes 1135 Can be greatly increased.

The fuel storage tank structure 1000 according to the present embodiment is configured such that when the fuel oil is discharged to the outside of the fuel storage tank 1100 in the first region 1100a which is a small region, The high temperature fuel oil H and the low temperature fuel oil L are introduced into one end of the fuel transfer pipe 1500 in an equal amount so that the fuel oil L is effectively mixed, And the low-temperature fuel oil (L) is discharged.

4 is a schematic view of a fuel supply system including a fuel storage tank structure according to an embodiment of the present invention.

Hereinafter, with reference to FIGS. 1 to 4, a process of supplying fuel oil to the fuel supply system 1 including the fuel storage tank structure 1000 according to an embodiment of the present invention will be described.

Referring to FIG. 4, the fuel supply system 1 can supply fuel oil to the main engine 10 of a ship (not shown). For example, the fuel supply system 1 may include a fuel storage tank structure 1000, a settling tank 20, and a service tank 30.

In this embodiment, the fuel storage tank 1100 can store the entire fuel oil required for the main engine 10 during a voyage (not shown) as shown in FIG.

The fuel oil stored in the fuel storage tank 1100 may be supplied to the settling tank 20 through the fuel transfer pipe 1500 as shown in FIG.

At this time, the fuel transfer pipe 1500 may be connected to the first branch line 51 at the other end. The first branch line 51 may be connected to an inlet (not shown) of the settling tank 20. In this case, the fuel oil stored in the fuel storage tank 1100 can be pumped by a pump (not shown) installed on the first branch line 51 and moved to the settling tank 20.

The settling tank 20 may have a small capacity as compared with the fuel storage tank 1100. [ For example, the settling tank can be made with a capacity that allows the ship to store fuel oil required for a day.

The fuel oil stored in the settling tank 20 can be heated to have a low viscosity that can be effectively supplied and consumed in the main engine 10. [ To this end, a heating device (not shown) such as a heating coil may be installed in the settling tank 20.

The heating of the fuel oil stored in the settling tank 20 can more effectively heat the fuel oil than the case of heating the fuel oil stored in the fuel storage tank 1100 and can prevent waste of energy.

On the other hand, the settling tank 20 can purify the fuel oil supplied from the fuel storage tank 1100.

The fuel oil heated in the settling tank 20 may be supplied to the service tank 30 connected to the settling tank 20. At this time, the fuel oil stored in the service tank 30 can be heated again by a heating device (not shown) provided in the service tank 30. [

The fuel oil stored in the service tank 30 may be supplied to the main engine 10 as required by the main engine 10. [

A portion of the heated fuel oil stored in at least one of the settling tank 20 or the service tank 30 is supplied to the fuel storage tank 1500 through the fuel transfer pipe 1500, (1100).

At this time, the other end of the fuel transfer pipe 1500 may be connected to the second branch line 52. The second branch line 52 may be connected to a discharge portion (not shown) of the settling tank 20 and a discharge portion (not shown) of the service tank 30. In this case, the heated fuel oil can be pumped to the fuel storage tank 1100 by a pump (not shown) installed on the second branch line 52.

At this time, the fuel supply system 1 may further include a heating device 40 such as a heating coil on the second branch line 52 as shown in FIG. In this case, the heating device 40 can further heat the heated fuel oil moving through the second branch line 52.

The high temperature fuel oil H which is heated in the process of being supplied to the fuel storage tank 1100 may be introduced into the first region 1100a through the fuel transfer pipe 1500 as shown in FIG. The high temperature fuel oil H flowing into the first region 1100a can be moved to the high temperature region 1110 and accommodated therein.

When the fuel oil in the first region 1100a is supplied to the settling tank 20, the high temperature fuel oil H contained in the high temperature region 1110 and the low temperature fuel oil L contained in the low temperature region 1130, The fuel can be introduced into one end of the fuel transfer pipe 1500 and mixed therewith. In this case, the medium temperature fuel oil may be supplied to the settling tank 20 through the fuel transfer pipe 1500.

The fuel supply system 1 according to the present embodiment supplies a part of the fuel oil heated in the settling tank 20 and the service tank 30 to the first region 1100a in the process of supplying the fuel oil, The process of supplying the fuel oil to the settling tank 20 can be repeated.

In this process, the medium-temperature fuel oil is repeatedly supplied to the settling tank 20, so that the efficiency of heating the fuel oil supplied to the settling tank 20 can be improved.

The fuel storage tank structure 1000 according to the present embodiment can be included in various fuel supply systems 1 configured to supply the medium temperature fuel oil of the first region 1100a directly to the main engine 10 Of course it is.

5 is a view showing a state where hot fuel oil is introduced into a first region of the fuel storage tank structure according to another embodiment of the present invention, and FIG. 6 is a cross- Fig.

5 and 6, the fuel storage tank structure 2000 according to the present embodiment includes a fuel storage tank 2100, a partition member 2300, a fuel transfer pipe 2500, and a cover member 2700 can do.

The fuel storage tank 2100 and the fuel transfer pipe 2500 according to the present embodiment are the same as those of the fuel storage tank (1100 of FIG. 1) and the fuel transfer pipe (1500 of FIG. The fuel storage tank structure 2000 according to the present embodiment is constructed such that the high temperature region 2110 and the low temperature region 2130 are covered with the cover member 2700 surrounding one end of the fuel transfer pipe 2500 disposed in the first region 2100a, Which is different from the previous embodiment.

[ The low temperature region 2130 is a part of the fuel oil stored in the first region 2100a and can receive the low temperature fuel oil L which is lower in temperature than the high temperature fuel oil H. [

The high temperature region 2110 and the low temperature region 2130 may be partitioned inside the cover member 2700.

For example, the interior of the cover member 2700 may be partitioned into the high temperature region 2110 and the low temperature region 2130 by a separating member 2150 arranged in the horizontal direction inside as shown in FIG. At this time, the high temperature region 2110 may be disposed on the upper side with respect to the low temperature region 2130.

The first movement passage 2111 and the second movement passage 2131 may be disposed inside the cover member 2700. [

5 and 6, the first transfer passage 2111 is provided in the process of being accommodated in the high temperature region 2110 at one end of the fuel transfer pipe 2500, It is possible to guide the movement of the high temperature fuel oil H in the course of flowing into the one end of the moving pipe 2500.

6, during the movement of the low temperature fuel oil L from the low temperature region 2130 to the one end of the fuel transfer pipe 2500, the second transfer passage 2131 moves the low temperature fuel oil L .

For example, the first moving passage 2111 may include a guide plate 2112 disposed inside the cover member 2700 and spaced apart from the outer surface of the fuel moving pipe 2500 as shown in FIG. 5, As shown in FIG.

At this time, an extension 2112a extending toward the center line C of the fuel transfer pipe 2500 may be formed at one end of the guide plate 2112 near the one end of the fuel transfer pipe 2500. The extension portion 2112a can cover a part of the lower portion of one end of the fuel transfer pipe 2500. [

The second moving passage 2131 may be formed between the extended portion 2112a formed at one end of the guide plate 2112 and the bottom portion of the low temperature region 2130 in the cover member 2700. [

A first communication hole 2115 and a second communication hole 2135 may be formed on a side surface of the cover member 2700. [

The high temperature region 2110 can communicate with the outside of the cover member 2700 through the first communication hole 2115. The low temperature region 2130 can communicate with the outside of the cover member 2700 through the second communication hole 2135. In this case, the outside of the cover member 2700 may be the first region 2100a.

At this time, the second communication hole 2135 may be formed close to the bottom of the low temperature region 2130. In other words, the second communication hole 2135 may be formed close to the bottom of the first region 2100a.

In this case, the fuel oil stored in the fuel storage tank 2100 can not be discharged to the outside of the fuel storage tank 2100 and is not consumed, and can be prevented from being left in the fuel storage tank 2100.
