Description

[0001] Anti-splash device [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus, and more particularly, to a splash preventing apparatus for preventing oscillation of an oil tank of an oil tanker.

The cargo tank of the tanker carries the cargo (liquid) which is dangerous to the explosion, and it should prevent the pressure or the vacuum from occurring more than necessary and keep the pressure inside the tank in the safe range.

Therefore, the tank is equipped with High Velocity Pressure / Vacuum Valves at the top of the cargo oil tank. That is, when the pressure inside the tank is higher than necessary, the valve is opened by the pressure regulating part of the pressure regulating valve to lower the pressure inside the tank. In addition, when a vacuum is generated inside the tank, the valve is opened by the vacuum control unit of the pressure control valve to suck outside air to protect the oil tank.

Cargo tanks may experience oil sloshing during loading or unloading of oil or during voyage of tanker. Thus, a sloshing force due to the flow of the fluid in the tank may be formed to be higher than the operating pressure of the pressure regulating valve in some areas. At this time, the total pressure inside the tank is less than the operating pressure but the valve can be opened. When the valve is opened, the fluid inside the tank may be discharged to the outside due to rocking, which may cause an oil spill.

Recently, there has been an increasing demand from consumers for eco-friendly vessels, eco-friendly vessels or green vessels. In order to respond to the demand of the International Maritime Organization (IMO) for oil spillage and the reduction of volatile organics, a technique for analyzing the fluctuation of the oil in the tank has been developed to reduce oil spillage.

1 is a perspective view showing a splash preventing apparatus 100 according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II in FIG. 1, and FIG. 3 is a cross- Fig.

1 to 3, the splash preventive apparatus 100 may include a case part 130, a first buffer part 140, and a second buffer part 150. The case 130 has a second opening 122 through which the fluid flows and a first opening 112 through which the fluid introduced from the second opening 122 is discharged. The first buffer unit 140 is installed in the inner space of the case part 130 to change the flow direction of the fluid passing through the second opening part 122. The second buffer unit 150 is disposed above the first buffer unit 140 and changes the flow direction of the fluid passing through the first buffer unit 140. The configuration and operation of each configuration will be described in detail below.

The case part 130 is connected to a pipe (not shown) of an oil tank (not shown) to form a part of a flow path through which the fluid in the oil tank passes. The case part 130 may be integrally formed and connected to the pipe, and the case part 130 may be detachable to facilitate installation and repair. Hereinafter, for convenience of description, a case in which the case part 130 is formed to be detachable and attachable will be mainly described.

The case part 130 may include a first case 110 and a second case 120. The first case 110 includes a first body portion 111, a first opening 112, an upper cover 113, a first duct 114, an upper flange 115, and a first flange 116 .

The first body part 111 may be formed in a circular or polygonal tubular shape to form an inner space of the case part 130. The first buffer unit 140 and the second buffer unit 150 may be installed in the inner space of the first body unit 111. [

The upper cover 113 is installed on the upper portion of the first body 111 and includes a first opening 112. The upper cover 113 prevents leakage of the case part 130 and guides the fluid passing through the case part 130 to pass through the first opening part 112.

The first duct 114 is formed to extend to the first opening 112 and is connected to an upper pipe (not shown). At this time, the upper pipe is connected to the upper pipe through the hole 115a of the upper flange 115. The first duct 114 may serve as a channel for discharging a part of the gas to the outside when the pressure inside the oil tank rises.

The second case 120 includes a second body portion 121, a second opening 122, a lower cover 123, a second duct 124, a lower flange 125, and a second flange 126 . The structure and shape of the second body part 121, the lower cover (), the second duct 124, the lower flange 125, and the second flange 126 correspond to the respective parts of the first case 110 And the detailed description will be omitted or outlined.

The second opening 122 serves to introduce the fluid of the oil tank. The diameter of the second opening 122 is formed to be the same as that of the first opening 112, so that the installation of the splash preventive device 100 can be facilitated.

The second flange 126 of the second case 120 and the first flange 116 of the first case 110 are coupled to each other to form the case 130. [ The holes 116a of the first flange 116 and the holes 126a of the second flange are aligned and fixed through the coupling member 170 in detail. The joining member 170 is not limited to a specific material and a joining method, and may be, for example, a bolt and a nut, a rivet, a weld, a screw, or the like. Hereinafter, for convenience of explanation, the first flange 116 and the second flange 126 are coupled with a bolt and a nut, respectively.

The first buffer unit 140 may have a bent plate shape or a shape in which a plurality of plates are combined while forming a predetermined angle. The first buffer unit 140 functions to change the flow direction of the fluid so that the fluid passing through the second opening 122 does not move upward. The first buffer part 140 may include a first plate 141, a second plate 142, a first bent part 143, and a first bent part 144.

The first buffer portion may include a first bend portion 143 formed to protrude toward the first opening portion 112. That is, the first buffer unit 140 may include a first bent portion 143 having a first angle? Toward the second opening 122. The first bent portion 143 is disposed on the upper portion of the center of the second opening 122 to effectively change the moving direction of the fluid flowing through the second opening 122.

Specifically, the first plate 141 and the second plate 142 are connected at their respective ends to form a first angle? Between the first plate 141 and the second plate. Here, the first angle? May be formed at an obtuse angle having an angle of not less than 90 degrees and not more than 180 degrees. In particular, the first angle? Has an angle of 100 degrees to 150 degrees or less, so that the pressure drop inside the case 130 can be minimized.

The first buffer portion 140 forms the first bent portion 143 in a region between the first angles?. The first bent portion 143 collides with the fluid introduced into the second case 120 through the second opening 122 to change the moving direction of the fluid. That is, the flow of the introduced liquid fluid is guided to the second opening 122 to prevent the leakage of the liquid fluid to the outside of the oil tank.

In the first buffer unit 140, the end of the first buffer unit 140 is fixedly connected to the inner wall of the case unit 130. At this time, a first vent portion 144 is formed between the inner wall of the case part 130 and the first buffer part 140. The high-pressure gas introduced from the second opening 122 passes through the first vent portion 144 and moves. Further, a portion of the liquid fluid not passed through the first bent portion 143 passes through the first vent portion 144 and moves upward.

The first vent portion 144 may include a first vent 144a and a second vent 144b depending on a position where the first vent 144 is formed.

The first vent 144a is formed at the end of the first plate 141 or at the end of the second plate 142 with a curved portion 145 in the form of an elongated hole. The curved portion 145 can increase the size of the cross-sectional area of the flow passage passing through the first vent portion 144, thereby allowing the fluid to move upward easily. The first vent 144a is formed adjacent to the second opening 122. When the gas inside the tank is discharged due to the pressure rise in the oil tank, Lt; / RTI >

The second vent 144b may be formed between a side of the end of the first plate 141 and an end of the second plate 142 and an inner wall of the second case 120. The second vent 144b rises upward toward the first opening 112 by the inclined surface of the first plate 141 and the inclined surface of the second plate 142. Therefore, when the high-pressure gas in the tank is discharged due to the pressure rise inside the oil tank, the pressure drop can be minimized, and the gas fluid can be easily discharged.

The second buffer unit 150 may be formed along the inner wall of the case unit 130 above the first buffer unit 140. The second buffer unit 150 changes the traveling direction of the fluid passing through the first buffer unit 140.

The second buffer unit 150 is installed to circulate along the inner wall of the first case 110 and is disposed at an upper portion of the first buffer unit 140, The flow direction can be changed.

A second vent portion 151 may be provided at the center of the second buffer portion 150 so that a high-pressure gas having passed through the first vent portion 144 flows out to the outside through the first opening portion 112. The shape of the second vent portion 151 is not limited to a specific shape and may have a multiple or circular hole shape. However, for the sake of convenience of description, a description will be given mainly of a circular hole shape similar to the shape of a pipe (not shown) connected to the splash preventive device 100. [

The second buffer unit 150 may be installed at a height of 2/3 to 4/5 of the height from the second opening 122 to the first opening 112. The installation position of the second buffer unit 150 is such that the liquid fluid passing through the first vent unit 144 is changed in flow by the second buffer unit 150 and the gas fluid Can easily flow out to the outside through the second vent portion 151.

The diameter of the second vent portion 151 may be larger than the diameter of the first opening 112 or the diameter of the second opening 122. This is to maintain the pressure in the inner space of the case part 130 at a low level by causing the high-pressure gaseous fluid that has passed through the second opening part 122 to quickly discharge through the first opening part 112. That is, the diameter of the first opening 112 or the diameter of the second opening 122 may be larger than the diameter of the second opening 122, so that the high-pressure gas can be easily discharged from the inner space of the case 130 to the outside.

The flow of the liquid fluid and the gas fluid inside the oil tank by the splash preventing apparatus 100 will be described as follows.

The liquid fluid and the high-pressure gas fluid stored in the oil tank (not shown) flows through the second duct 124 connected to the pipe (not shown). After passing through the second duct 124, the liquid fluid and the high-pressure gas fluid flow into the inner space of the case part 130 through the second opening part 122.

Liquid fluids are viscous and have a weight greater than the gas, so the flow rate is slower than the gas fluid. The liquid fluid hits the first bending portion 143 of the first buffer portion 140 and moves to the second opening portion 122 along the lower inclined surfaces of the inclined first plate 141 and the second plate 142 do. The liquid fluid having moved to the second opening 122 may be moved to the oil tank through the second duct 124 and then stored and transported.

A portion of the liquid fluid may pass upward through the first vent portion 144. At this time, a part of the fluid moving upward may strike the second buffer unit 150 and then move downward by changing the flow direction. In other words, the fluid passing through the first vent portion 144 and moving upward flows through the second buffer portion 150, and the direction changes, because the second buffer portion 150 is formed in the traveling direction of the fluid. At this time, the first vent 141 can be easily moved along the upper inclined surface of the first plate 141 or the second plate 142 of the first buffer unit 140. The liquid fluid moved to the first vent portion 144 may be moved to the second opening 122, moved to the oil tank through the second duct 124, and then stored and transported.

Gaseous fluids form high pressures and are low in weight and therefore have fast diffusion and flow rates. The gas fluid moves from the high pressure to the low pressure, and moves from the lower part of the case part 130 toward the upper part. Specifically, the gas fluid hits the first bending portion 143 of the first buffer portion 140 and moves along the lower inclined surfaces of the first plate 141 and the second plate 142. The gas fluid does not have a viscosity and is formed at a high pressure. The gas fluid moves along the lower inclined surface of the first buffer part 140, and then moves upward through the first vent part 144.

The gas fluid having passed through the first vent portion 144 moves through the space between the upper inclined surface of the first buffer portion 140 and the second buffer portion 150 and then passes through the second vent portion 151 Can be moved. The gas fluid that has passed through the second vent portion 151 may pass through the first opening portion 112, move to the first duct 114, and be discharged to the outside.

The first buffer unit 140 and the second buffer unit 150 can change the flow direction of the liquid fluid to prevent leakage of the liquid fluid to the outside. It is also possible to increase the predictability of the flow pattern of the liquid fluid, thereby facilitating the storage and transport of the liquid fluid in the oil tank.

The gas fluid moves along the inclined surface of the first buffer part 140 to easily form the flow of the gas fluid. Also, the high-pressure gas fluid can easily be discharged to the outside through the second vent portion of the second buffer portion 150. [ Thus, the internal pressure of the oil tank (not shown) and the anti-splash device 100 can be kept constant.

4 is a perspective view showing a splash preventing apparatus 200 according to another embodiment of the present invention. 5 is a cross-sectional view taken along line V-V in FIG. 4, FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 4, and FIG. 7 is a cross-sectional view taken along line VII-VII in FIG.

4 to 7, the splash preventive device 200 may include a case part 230, a first buffer part 240, and a second buffer part 250. As shown in FIG. However, the other parts of the splash preventive device 200 are the same as those of the splash preventive device 100 of the first embodiment, except that the components of the first buffer part 240 are characteristically different. Therefore, in the description of the present embodiment, the description of the splash preventive device 100 of the first embodiment is omitted, and a detailed description thereof will be omitted.

The first buffer unit 240 may have a bent plate shape or a shape in which a plurality of plates are combined while forming a certain angle. The first buffer unit 240 functions to change the flow direction of the fluid so that the fluid that has passed through the second opening 222 does not move upward. The first buffer unit 240 includes a first plate 241, a second plate 242, a third plate 243, a fourth plate 244, a first bend unit 245, a second bend unit 246 And a first vent portion 247,

The first buffer portion 240 may include a first bent portion 245 having a first angle a toward the second opening 222. The first plate 241 and the second plate 243 are connected at their respective ends to form a first connection part a and the third plate 243 and the fourth plate 244 are connected at their respective ends Thereby forming a second connecting portion b. The first buffer part 140 forms a first angle? Between the first connection part a and the second connection part b. Also, the first angle? May be formed at an obtuse angle having an angle of 90 degrees or more and 180 degrees or less. In particular, the first angle alpha may have an angle between 100 degrees and 150 degrees.

The first buffer portion 140 may include a second bent portion 246 having a second angle? Toward the first opening 112. In detail, the first plate 241 and the third plate 243 are connected to each other to form a third connection part c, and the second plate 242 and the fourth plate 244 are connected at their respective ends Thereby forming a fourth connecting portion d. The first buffer portion 140 forms a second angle? Between the third connection portion c and the fourth connection portion d. Also, at this time, the second angle? May be formed at an obtuse angle having an angle of not less than 90 degrees and not more than 180 degrees. In particular, the second angle beta has an angle of 120 degrees to 170 degrees, so that the pressure drop inside the case part 230 can be minimized.

In the first buffer unit 240, an end of the first buffer unit 240 is fixedly connected to an inner wall of the case unit 230. At this time, a first vent portion 247 is formed between the inner wall of the case portion 230 and the first buffer portion 240. The high-pressure gas introduced from the second opening portion 222 passes through the first vent portion 247 and moves. Further, a part of the liquid fluid not passed through the first bent portion 245 passes through the first vent portion 247 and moves.

The first vent 247 may include a first vent 247a and a second vent 277b depending on the position of the first vent 247. The first vent 247a has an end portion of the first connection portion a forming the first angle alpha and a curved portion 248 in the shape of a slot in the end portion of the second connection portion b. The curved portion 248 can enlarge the size of the cross-sectional area of the flow passage passing through the first vent 247a so that the fluid easily moves upward.

The second vent 247b is formed at the end of the third connecting portion c and the end of the fourth connecting portion d forming the second angle beta. The second vent 247b is located at the upper portion of the tank. When the gas in the tank is discharged due to an increase in pressure in the oil tank, the gas can be easily discharged by tilting the tank upward to minimize the pressure drop. That is, the second vent 247b secures an area required for discharging the gas when the gas needs to be discharged due to the pressure rise in the oil tank. Accordingly, the gas fluid moves along the lower inclined portion of the first buffer portion 240 to form an upward flow through the second vent 247b, and the gas fluid can easily be discharged to the outside through the first opening portion 212 .

The flow of the liquid fluid and the gas fluid inside the oil tank by the splash preventer 200 will be described as follows.

The liquid fluid and the high-pressure gas fluid stored in the oil tank (not shown) flows through the second duct 224 connected to the pipe (not shown). After passing through the second duct 224, the liquid fluid and the high-pressure gaseous fluid flow into the inner space of the case part 230 through the second opening part 222.

Liquid fluids are viscous and have a weight greater than the gas, so the flow rate is slower than the gas fluid. The liquid fluid hits the first bent portion 245 of the first buffer portion 240 and moves to the second opening portion 222 along the inclined surfaces of the inclined first to fourth plates 241 to 244 . The liquid fluid having moved to the second opening 222 can be moved to the oil tank through the second duct 224 and then stored and transported.

A portion of the liquid fluid may pass upward through the first vent portion 247. At this time, a part of the fluid moving upward may strike the second buffer unit 250 and then move downward by changing the flow direction. In other words, the fluid passing through the first vent portion 247 and moving upward flows through the second buffer portion 250 and the direction is changed because the second buffer portion 250 is formed in the moving direction of the fluid. At this time, it is possible to easily move to the first vent 247a along the inclined surfaces of the first plate 241 to the fourth plate 244 of the first buffer unit 240. [ That is, the second bent portion 246 collects the liquid fluid into the first vent 247a and can easily move the liquid. The liquid fluid moved to the first vent 247a may be moved to the second opening 222 and then moved to the oil tank through the second duct 224 and then stored and transported.

Gaseous fluids form high pressures and are low in weight and therefore have fast diffusion and flow rates. The gas fluid moves from the high pressure to the low pressure and moves from the lower part of the case part 230 toward the upper part. Specifically, the gas fluid hits the first bent portion 245 of the first buffer portion 240 and moves along the lower inclined surfaces of the first to fourth plates 241 to 244 inclined. The gas fluid does not have viscosity and is formed at a high pressure. The gas fluid moves along the lower inclined surface of the first buffer portion 240, and then moves upward through the first vent portion 247.

The gas fluid that has passed through the first vent portion 247 moves through the space between the upper inclined surface of the first buffer portion 240 and the second buffer portion 250 and then passes through the second vent portion 251 Can be moved. The gas fluid that has passed through the second vent portion 251 may pass through the first opening 212 and may move to the first duct 214 and be discharged to the outside.

The first buffer unit 240 and the second buffer unit 250 can change the flow direction of the liquid fluid to prevent leakage of the liquid fluid to the outside. It is also possible to increase the predictability of the flow pattern of the liquid fluid, thereby facilitating the storage and transport of the liquid fluid in the oil tank.

The liquid fluid moves along the inclined plane along the first angle alpha and the second angle beta of the first buffer unit 240 to easily recover the liquid fluid which is returned to the inside of the oil tank (not shown).

The gaseous fluid moves along the inclined surface along the first angle alpha and the second angle beta of the first buffer portion 240 to easily form the flow of the gas fluid. Further, the high-pressure gas fluid can easily be discharged to the outside through the second vent portion 251 of the second buffer portion 250. Thus, the internal pressure of the oil tank (not shown) and the splash prevention device 200 can be kept constant.

The following describes experimental data that the splash preventing devices 100 and 200 reduce the velocity of the fluid in the tank to ensure fluid stability.

The stability of the liquid fluid can be examined by providing the splash preventer 200 through Table 1 below.

The experiment measured the flow rate in the ascending direction of the liquid fluid at the center of the first opening 212. The unit of the experiment is the degree (DEG) and the height is mm. The velocity measures the velocity of the fluid in the first opening 212 and the velocity has a direction from the second opening 222 toward the first opening 212 and the unit is m / s.

The first angle alpha of the splash preventive device 200 is set to 120 degrees, and the size of the pipe has 150A. The distance between the second opening 222 and the first opening 212 is 300 mm, and the diameter of the case 230 is 355.6 mm. Variables for setting the positions of the first buffer unit 240 and the second buffer unit 250 include angles and heights. The angle is a second angle beta and the height is a height at which the second buffer unit 250 is installed, and is a distance provided apart from the second opening 222.

In the control group in which the splash preventer 200 is not installed, the flow rate is rapidly formed at the initial stage of the sloshing. Since the flow velocity is reduced at a high speed after that, the flow of the liquid fluid due to the occurrence of the fluctuation can not be predicted, and the liquid fluid can flow out to the outside due to the abrupt flow velocity generated at the beginning.

The flow rates at each time in the cases 1 to 10 are formed almost constant. That is, even if the swinging motion is formed in each case, the swinging motion does not occur suddenly and the swinging motion proceeds slowly, so that the flow mode of the liquid fluid can be predicted. Also, the amount of the liquid fluid that flows out to the outside can be minimized because no rapid fluctuation occurs at the initial stage.

Table 2 below shows the flow rate of each case measured by using the artificial neural network (ANN) in the splash preventing apparatuses 100 and 200, and it is possible to examine whether the flow stability of the fluid inside the tank is stable.

The optimal design program using the artificial neural network technique compares the flow rate measured in the ascending direction of the liquid fluid at the center of the first opening 212. The unit of the experiment is the degree (DEG) and the height is mm. The velocity measures the velocity of the fluid in the first opening 212 and the velocity has a direction from the second opening 222 toward the first opening 212 and the unit is m / s. The experimental artificial neural network program was implemented using 'K-Metal ANN'.

The first angle of the splash preventive device 200 is formed to have 120 degrees, and the size of the pipe has 150A. The distance between the second opening 222 and the first opening 212 is 300 mm, and the diameter of the case 230 is 355.6 mm. Variables for setting the position include angle and height. The angle is a second angle beta and the height is a height at which the second buffer unit 250 is installed, and is a distance provided apart from the second opening 222.

When the simulation is predicted using the optimization program, the flow rate of the ascending fluid at the center of the first opening portion 212 when the splash preventing device 200 is installed is formed to be 2.8 m / s to 2.4 m / s. Therefore, compared with the case in which the splash prevention device 200 of Table 1 of the fluid is not provided, the flow stability of the fluid can be ensured and the shape of the flow can be predicted.

The case 6 is formed at a second angle? Of 180 degrees, which is similar to the anti-splash device 100 according to an embodiment of the present invention.
