The present invention relates to a multipurpose seawater exchange apparatus having a ballast water sediment treatment function of a ship, and more particularly, in a ballast system having a function of watering and draining ballast water for stability of a ship, separate sediment removal It is possible to treat the sediment accumulated in the ballast tank without installing the device, and to provide a multi-purpose seawater exchange device that can also treat microorganisms by heating the ballast water discharged from the ballast tank.

 In general, ballast tanks of ships are designed for safe navigation by lowering the center of gravity of ships as they are loaded and unloaded. Several ballast tanks are installed to be symmetrical from side to side, and each ballast tank is formed in an independent room structure. . As a result, the seawater introduced into the ballast tank may not move to the inside of the different tanks.

 As shown in FIG. 1, the ballast system according to the related art includes two pumps 9 mounted in an engine room formed at the stern of the ship 1, and a seawater inflow pipe connected from the pump 9 to the outside of the ship. (7), and one end is connected to the pump (9) and the other end is extended to the fore and aft direction inside the hull, one end is connected to the main pipe (5) and the other end is Branch pipe (11) located inside the ballast tank (3), control valve (15) mounted on the branch pipe (11) and bell mouse (17) mounted at the other end of the branch pipe (11) It includes.

 When water is supplied to the ballast tank 3, the pump 9 is driven to supply seawater, that is, ballast water outside the hull, to the main pipe 5 from the seawater connecting pipe 7. Thereafter, the ballast water supplied to the main pipe 5 is supplied into each ballast tank 3 along the branch pipe 11. At this time, a bell mouse 17 is mounted at the other end of the branch pipe 11, and the ballast water is supplied into the ballast tank 3 through the bell mouse 17. In addition, although the control valve 15 is mounted on the branch pipe 11, the supply of ballast water may be interrupted by adjusting the control valve 15.

On the other hand, when draining the ballast water from the ballast tank (3) is operated in the opposite way to the water supply described above, if the pump (9) is driven in reverse, the ballast water in the ballast tank (3) inside the ballast tank (3) The discharged through the 17, the discharged ballast water is discharged to the main pipe (5) along the branch pipe (11). At this time, the control valve 15 is mounted on the branch pipe (11), it is possible to block the discharge of the ballast water by the control of the control valve (15). Thereafter, the ballast water discharged along the main pipe 5 is discharged to the outside of the hull through the seawater connecting pipe (7).

As described above, in the conventional ballast system, one bell mouse 17 is installed in one ballast tank 3 so that water supply and drainage of ballast water in the ballast tank 3 is made through the same bell mouse 17. To lose.

However, as the ship is repeatedly loaded and lowered according to the navigation of the ship, the seawater is filled and drained into the ballast tank 3 repeatedly. At this time, various solids such as sediments are introduced into the ballast tank 3 together with seawater, and are accumulated in most regions except for the surroundings of the bell mouse 17 having a relatively high flow rate. Therefore, in order to prevent accumulation of such deposits, a separate ballast tank deposit removal apparatus was required.

Ballast tank sediment removal device of the vessel according to the prior art is a patent application technology, it is disclosed in the Republic of Korea Patent Application No. 13,387,2000.

Figure 2a is a schematic diagram before showing the ballast tank sediment removal device of a conventional vessel. As shown in FIG. 2A, the sediment removal device of the ballast tank 3 of the vessel 1 operates the pump 22 installed in the engine room to discharge seawater from the seawater inlet 20 to the main water supply pipe 24 inside the hull. ), And then supply the supplied seawater to the plurality of injection pipes 28 connected to the main water supply pipe 24, to inject seawater from the ballast tank (3). In addition, a valve 26 is attached to the connection portion between the main water supply pipe 24 and the injection pipe 28.

Figure 2b is a partial perspective view of the injection pipe of the ballast tank sediment removal device of the conventional vessel shown in Figure 2a. As shown in FIG. 2B, when the valve (not shown) mounted at the connection portion between the main water supply pipe (not shown) and the injection pipe 28 is opened, seawater supplied to the main water supply pipe flows into the injection pipe 28. do.

The injection pipe 28 is mounted on the upper portion of the longage 32 so as to be perpendicular to the longi 32 direction of the ballast tank 3. At this time, the injection pipe 28 is densely mounted in a plurality of web (Web, not shown) interval. In addition, there are a plurality of injection holes 30 in the lower portion of each injection pipe 28, the injection pipe 28 is mounted so that a plurality of fine injection holes 30 are located between the longage (32).

Therefore, the seawater injected at high speed through the injection hole 30 of the injection pipe 28 removes the deposits accumulated between the longages 32 of the ballast tank 3 from the bottom surface.

However, since the ballast tank sediment removal device of a conventional ship is a separate device from a ballast system that is responsible for the supply and drainage of ballast water in a ballast tank of a ship, a plurality of injection pipes are additionally installed for each ballast tank, There is a problem of cost.

 In addition, the ballast tank sediment removal device of the conventional vessel is a form in which a plurality of injection pipes are mounted in each ballast tank, due to this compact structure, there is a lot of inconvenience in maintaining, repairing and cleaning the deposit removal device.

In addition, the ballast tank sediment removing device of the conventional vessel does not use the pump used in the conventional ballast system, and because it uses a separate pump, there is a problem that additional cost is generated in the running side of the vessel.

In addition, since there are various microorganisms in each region in the sediment, there is a problem such as marine pollution and ecosystem disturbances that may occur when discharged to the ocean of other regions without removing them.

An object of the present invention devised to solve the above problems is in the ballast system having a ballast function, it is possible to remove the ballast water exchange and sediment, and further process the microorganisms present in the ballast water during discharge of the ballast water. The present invention provides a multipurpose seawater exchange device having a function of treating ballast water sediment of a ship.

As described above, an object of the present invention is to provide a plurality of pumps for supplying or draining seawater into a ballast tank, a main pipe connected to the pump, and one end connected to the main pipe. And the other end includes a first branch pipe located inside the ballast tank, a first control valve mounted on the first branch pipe, and a Bellmouth mounted on the other end of the first branch pipe. In the ballast system of the ship, one end is connected to the main pipe, the other end is a second branch pipe extending from the inside of the ballast tank to the ship side; A second control valve mounted on the second branch pipe; And a plurality of feedwater headers mounted at predetermined intervals on the second branch pipe.

In addition, an object of the present invention is a multi-purpose seawater exchanger having a ballast water sediment treatment function of a ship having a ballast tank arranged in a plurality of pairs in pairs, piped in the stern-bow direction, the bell at one side of the even-row ballast tank A pair of drainage side first branch pipes with a mouse coupled to the left and right tanks, and a pair of water supply side second branch pipes with a water supply header coupled to the left and right tanks on the other side of the odd row ballast tank. Subjective department; Piped side by side with the first main pipe, one side of the odd-numbered ballast tank is connected to the pair of drainage side first branch pipes coupled to the left and right tanks, the other side of the even-numbered ballast tank is coupled to the water supply header A pair of water supply-side second branch pipes includes the second main pipe connected to the left and right tanks, and the first main pipe and the second main pipe are coupled to a pump for water supply and drainage. It is achieved by a multipurpose seawater exchanger with ballast water sediment treatment.

In addition, when the ballast water in the ballast tank is exchanged and the sediment is treated, seawater is selectively supplied into the ballast tank through the water supply header by opening and closing the second control valve, and opening and closing the first control valve. It is preferable to selectively drain from the ballast tank through the first branch pipe. Due to this, the seawater discharged from the feed head mounted on the bow side of the ballast tank moves at a high flow rate between the Longi of the ballast tank, separating the sediment from the bottom of the ballast tank and then mixing with the sediment. The ballast water is discharged to the bell mouse mounted on the stern side of the ballast tank.

Further, in each of the ballast tanks, the second branch pipe is located on the bow side and the first branch pipe is located on the stern side, and the sediment in the ballast tank by the seawater discharged from the water supply header of the second branch pipe. It is preferable that the seawater including the precipitate is drained by the bell mouse of the first branch pipe at the same time.

In addition, when only water supply or drainage of the ballast water in the ballast tank is performed, the first control valve is opened and the second control valve is shielded so that the ballast water is supplied only to the first branch pipe through the bell mouse. It is preferable to drain. It is mounted on the second branch pipe so as not to use the water supply head used for removing the sediment when it is not necessary to remove the sediment in the ballast tank, that is, when only the ballast water is supplied to or drained from the ballast tank. To shield the second control valve. Therefore, by opening only the first control valve mounted on the first branch pipe, it is possible to supply or drain water with only one bell mouse to one ballast tank, thereby performing a conventional ballast system function.

In this case, it is preferable that a plurality of injection holes are formed in the lower portion of the water supply header so as to inject seawater at a high flow rate between longages. As a result, the ballast water supplied to the second branch pipe is discharged at a high flow rate by a plurality of injection holes formed in the lower portion of the water supply head, whereby the sediment is separated from the bottom surface of the ballast tank to float in the ballast water.

In addition, it is preferable to further include a heater for heating the ballast water discharged from the inside of the ballast tank by the pump. Therefore, when discharging the ballast water from the inside of the ballast tank to the outside of the hull, microorganisms present in the ballast water can be treated.

In addition, the heater is preferably a heat exchanger (Heat Exchanger) for heating the ballast water by using the exhaust heat of the steam discharged from the boiler of the ship or the propulsion engine. As a result, it is possible to save energy separately used for operating the heater.

In addition, before the ballast water discharged from the inside of the ballast tank by the pump is heated by the heater, it is preferable to heat the ballast water with high temperature seawater discharged from the cooler of the vessel. At this time, the ballast water discharged from the inside of the ballast tank is a low temperature, since the seawater discharged from the various coolers mounted on the vessel is a high temperature, by first mixing the ballast water and the seawater discharged from the cooler, it is possible to increase the temperature of the ballast water have. For this reason, the energy consumed by the heater for heating ballast water can be saved.

At this time, prior to the detailed description of the present embodiment, in order to help the understanding of the present embodiment, the configuration of the ballast tank used in the present embodiment will be briefly described.

The ballast tanks of the ship are formed in two rows by forming a plurality of left and right along the centerline of the ship.The ballast tanks having the same order are again placed left and right along the centerline of the ship. Each is placed independently. At this time, when looking at the athlete from the stern, the ballast tank located on the left side is called a port ballast tank, and the ballast tank located on the right side is called a starboard ballast tank. At this time, the port ballast tank and the starboard ballast tank having the same order are watered or drained by the same pump, main pipe, first branch pipe, and second branch pipe.

In the drawings, Figure 4 is a partial perspective view showing the inside of the ballast tank of one embodiment of the multi-purpose seawater exchange apparatus having a ballast water sediment treatment function in the ballast tank according to the present invention.

As shown in FIG. 4, a plurality of “T” -type long paper stiffeners (hereinafter referred to as long papers 104) are mounted on the lower portion of the ballast tank 100 at regular intervals. At this time, the second branch pipe 118 is mounted on the upper side of the bow side 104, one end of the second branch pipe 118 is connected to the main pipe (not shown), the other end is The ballast tank 100 extends from the inside to the ship side.

 A plurality of water supply headers 110 are mounted below the second branch pipe 118. The water supply header 110 has a predetermined interval, and is installed one by one between the plurality of longages 104, for this reason, the ballast water supplied to the second branch pipe 118 through the water supply header 110 This is to discharge evenly between each of the longage (104). As a result, a large flow of seawater from the water supply header 110 is discharged at a high speed to the bottom surface 102 between the longages 104, and the deposit accumulated on the bottom surface 102 is discharged from the bottom surface 102. It can be removed.

A plurality of holes (not shown) are formed at the bottom of the web so that the number of ballasts can pass each other.

In the drawings, Figure 5 is a conceptual diagram for explaining an embodiment of a multipurpose seawater exchange apparatus having a ballast water sediment treatment function of the ship according to the present invention.

 As shown in FIG. 5, the multipurpose seawater exchange apparatus according to the present invention is operated by a plurality of pumps. In this embodiment, two pumps, that is, a first pump 112 and a second pump 122, are used.

First, the roles of the two pumps 112 and 122 will be briefly described. In the case of exchanging ballast water and removing sediment in the ballast tank 100, the first main pipe (not shown) is connected to the first agent. One pump 112 is responsible for water supply of the port ballast tank 100 and the starboard tank 100 having an odd order through the first main pipe, the port ballast tank 100 and the starboard tank having an even order It is in charge of drainage of 100. On the contrary, the second pump 122 connected to the second main pipe (not shown) is responsible for supplying the pot ballast tank 100 and the starboard tank 100 having an even order and having an odd order. It is in charge of drainage of the ballast tank 100 and the starboard tank 100.

In addition, when only the water supply and drainage of the ballast water in the ballast tank 100 is performed, the first pump is responsible for the water supply and drainage of the port ballast tank and the starboard tank having an even order, and the second pump Responsible for water supply and drainage of tanks than port ballast tanks and stars with odd turn numbers.

As such, the first pump 112 and the second pump 122 may perform both water supply or drainage, among which FIG. 5 supplies the ballast water from the first pump 112 to the first pump 112. An embodiment of draining ballast water from two pumps 122, that is, an embodiment of a multi-purpose seawater exchange apparatus in a port ballast tank 100 and a starboard tank 100 having an odd order is illustrated.

The ballast water supplied from the first pump 112 is supplied to the ballast tank 100 having an odd order along the first main pipe and the second branch pipe. At this time, a plurality of water supply headers 110 are installed at the lower portion of the second branch pipe, and a large amount of seawater passing through them is discharged to the bottom surface 102 between the respective longines 104. In addition, a second control valve 114 is mounted on the second branch pipe, any ballast tank 100 of the ballast tank 100 having an odd order by opening and closing of the second control valve 114. The water supply to the furnace may be shut off.

A large amount of seawater discharged into the ballast tank 100 through the water supply header 110 flows on the bottom surface 102 between the longines 104 formed in the ballast tank 100, and the bottom surface. The sediment accumulated at 102 is removed and moved to the opposite side of the feedwater header 110. At this time, a plurality of holes 106 perforated at a predetermined interval are formed in the lower wall surface of the longage 104, the ballast water containing the sediment separated from the bottom surface penetrates the holes 106 It is possible to pass between the long 104.

One bell mouse 120 is mounted on the opposite side to which the water supply header 110 is mounted in the ballast tank 100. The bell mouse 120 is a funnel-shaped pipe inlet, and is shaped to facilitate suction and discharge of a large amount of flow at the same time. In another embodiment, the number and shape of the bell mouse 120 may be modified little by little. On the other hand, the ballast water including the precipitate passed through the ballast tank 100 is introduced into the bell mouse (120). At this time, the ballast water flowing into the bell mouse 120 is discharged by the second pump 122 along the first branch pipe and the second main pipe connected to the bell mouse 120, and on the first branch pipe. The discharge of the ballast water may be blocked by controlling the opening and closing of the mounted first control valve 124.

On the other hand, the ballast water containing the sediment discharged in the above manner is discharged to the seawater connecting pipe (not shown) formed on the outside of the hull, wherein the ballast water is present in a number of microorganisms. If such microorganisms are included in the ballast water and discharged to the sea, microorganisms in other regions may be spread into the ecosystem of a specific region, thereby causing disruption of the marine ecosystem. In order to prevent such a risk, a preferred embodiment of the present invention proposes a method for treating microorganisms present in ballast water to be discharged to the sea.

As a method for treating such microorganisms, a method of pre-heating ballast water to be discharged to the sea is used, for which a heater is used. That is, the ballast water discharged from the inside of the ballast tank 100 by the second pump 122 passes through the heater first before being discharged to the sea through the seawater connecting pipe. At this time, in the preferred embodiment of the present invention, the heat exchanger 140 using the exhaust steam discharged from the boiler 150 of the ship as the heater is used.

The heat exchanger 140 is a device for heating the ballast water discharged from the ballast tank by the hot exhaust steam 152 discharged from the various boilers 150 mounted on the vessel. Thereafter, the exhaust steam 154 changed into a low temperature state after heating the ballast water flows back into the boiler 150. It is intended to carry out a continuous iteration process. Therefore, the microorganisms present in the ballast water are all heated, and can no longer survive inside the ballast water. Afterwards, the ballast water, including the precipitate treated to the microorganisms, is discharged to the sea.

In this case, before the ballast water discharged from the inside of the ballast tank 100 by the second pump 122 is heated by the heat exchanger 140, the first step of heating the ballast water is performed. In order to increase the temperature by mixing in advance with the ballast water to discharge the high temperature seawater discharged after being used in the cooler 130 of the vessel.

On the other hand, in the case of the multi-purpose seawater exchanger having a ballast water sediment treatment function in the port ballast tank 100 and the starboard tank 100 having an even number among the ballast tanks 100, the method described above, The ballast water is supplied by the second pump 122 and the ballast water is drained by the first pump 112. That is, the positions of the first pump 112 and the second pump 122 shown in FIG. 5 are interchanged with each other.
