The present invention relates to a marine vessel ballast water treatment system using ozone microbubbles and bromine.

A ship is widely used as a means of transporting large quantities of goods at once or for military purposes.

If there are not enough people, equipment, and goods (collectively referred to as cargo), the ship will not sink sufficiently into the water, so it can be easily shaken by small waves, and even propellers and rudders are not sufficiently immersed in water. It is not operated efficiently.

Therefore, ships unloading freight are operated with ballast water containing ballast water in order to maintain balance and stability. As a result, the ballast water serves as a weight to adjust the ship's draft and trim.

On the other hand, when a ballast tank receives ballast water and arrives at a port in another region or another country, the ballast water is discharged to the sea of the destination to reduce the weight of the ship and load the cargo again.

Thus, while the ballast water is essential for maintaining the balance and stability of the ship, the ballast water is stored in the ballast tank for a long time, and also serves to mix the seawater belonging to different regions of the ballast water with each other And for these reasons, the following are a number of damages:

First, since the ballast water is stored in the ballast tank for a long time, various kinds of germs can be caused to grow.

Second, it can cause the ecosystem to be destroyed by mixing marine alien species belonging to different regions. For example, if a creature or pathogen in a specific area of the ballast water is transported by a ship containing ballast water to an entirely different area in the sea, the mixture of different ecosystems is mixed to disturb the ecosystem. There is a concern that it will cause serious damage to the coastal industry or other commercial activities or resources.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view for explaining a marine vessel ballast water treatment system using ozone microbubbles and bromine according to an embodiment of the present invention; FIG.

Referring to FIG. 1, a desalination vessel ballast water treatment system using ozone microbubbles and bromine according to an embodiment of the present invention (hereinafter, referred to as 'a desalination vessel ballast water treatment system') includes a compressor 101, The air dryer 103, the air receiver tank 105, the oxygen generator 107, the oxygen storage tank 109, the ozone generator 111, the central control unit 113, the chiller 115, the ozone gas destruction unit 119, An ozone ultrafine bubble generator 200, an AP tank 401 for storing water, and a bromine supply unit 403 capable of providing bromine.

The bromine supplier 403 may include, for example, an apparatus for storing an aqueous solution of bromine, or an apparatus for receiving bromine powder and dissolving the supplied bromine powder in water to prepare an aqueous solution of bromine.

The bromine powder may be KBr, or NaBr, but the bromine powder that may be used in the present invention is not limited thereto.

The present ballast water treatment system can perform an operation of sterilizing the fresh water introduced as ballast water (hereinafter, referred to as 'sterilization mode') and a mode of discharging the sterilized fresh water to the outside ('discharge mode') have. Hereinafter, the operation of each component will be described with reference to a sterilization mode in which the fresh water for ship-borne ship ballast water treatment is sterilized as ballast water.

The compressor 101 receives air from the outside, compresses it, and supplies the compressed air to the air dryer 103. Here, the air flowing into the air dryer 103 can be cooled by the chiller 115.

The air dryer 103 dries the air introduced from the compressor 101 and stores the air in the air receiver tank 105.

The oxygen generator 107 receives the air stored in the air receiver tank 105, generates oxygen, and stores the oxygen in the oxygen storage tank 109.

The ozone generator 111 receives the oxygen stored in the oxygen storage tank 109 and generates ozone gas. In this embodiment, a large amount of heat is generated in the ozone generator 111, so that the ozone generator 111 can be cooled by the chiller 115 or a cooler (not shown).

The central control unit 113 can control the operation of each device.

The ozone ultra-fine bubble generator 200 receives the ozone gas generated by the ozone generator 111 and can generate ultra-fine ozone in the ballast water inflow main line.

When the ozone gas destruction portion 119 needs to destroy the ozone gas present in the ozone gas inflow line, the ozone gas destruction portion 119 can discharge the ozone gas to the atmosphere after destroying the ozone gas.

In the sterilization mode, valve V11, valve V41, valve V43, valve V45 and valve V33 are opened and valve V34 is closed.

The opening or closing of these valves may be done manually or automatically by a control device such as the central control 113. In addition, the above-described valves may be disposed between the respective components as shown in FIG. 1, and this is for illustrative purposes only, so that the position of the valves or the line through which the ballast water flows can be changed within the spirit of the present invention have. These modifications are the same in the drawings to be described with reference to the other drawings.

In the sterilization mode, the ballast pump P33 pumps the ballast water into the ballast water inflow main line L31, and the drive water pump P32 pumps the stored water stored in the AP tank to the ozone ultra- (200).

Further, in the sterilization mode, the bromine pump P43 pumps the bromine solution from the bromine solution supply unit 403 and supplies the water (seawater, fresh water, or nadir) discharged from the AP tank 401 by the drive water pump P32 ). Thereafter, the water containing bromine is supplied to the ozone ultra-fine bubble generator 200 by the drive water pump P32.

The embodiments of the present invention are intended to solve the problem that the TRO concentration can not be maintained due to the absence of bromine in fresh water.

In the embodiment of FIG. 1, it is intended to increase the reactivity between bromine and ozone gas, so that bromine is reacted with ozone gas first without being directly injected into the ballast water inflow main line L31. However, this configuration is exemplary and it is also possible that the bromine is directly injected into the ballast water inflow main line.

The water filled in the AP tank 401 may be any of seawater, fresh water, and water.

The ozone ultra-fine bubble generator 200 generates ozone ultra-fine bubbles in the ballast water inflow main line L31. The ballast water inflow In the main line (L31), the ultra-minute ozone bubbles kill the creatures in the ballast water.

The AP tank 401 is a place where seawater, fresh water or nautical water is stored and the seawater, fresh water or nose stored in the AP tank 401 is pumped by the drive water pump P32 to be supplied to the ozone ultrasonic bubble generator 200 ).

It is preferable that the pump P43 is operated only when the vessel equipped with the present containment vessel equilibrium water treatment system is in operation in fresh water or nautical water, and not in operation in sea water.

The TRO sensor 305 senses the TRO concentration after the ozone ultrafine bubbles containing ozone gas are introduced into the ballast water by the ozone ultrafine bubble generator and transmits the sensing result to the central control unit 113 .

The central control unit 113 receives the TRO concentration sensing result from the TRO sensor 305 and compares the reception result with the previously stored reference range and controls the ozone gas amount control valve 117 to control the ozone gas amount .

For example, when the TRO concentration sensed by the TRO sensor 305 is equal to or greater than the reference range, the central control unit 113 closes the ozone gas amount control valve to some extent and supplies a smaller amount of ozone to the ozone gas inflow line L33 Allow gas to flow.

On the other hand, when the TRO concentration sensed by the TRO sensor 305 is below the reference range, the ozone gas amount control valve is opened to some extent so that more ozone gas flows into the ozone gas inflow line L33.

In this way, the central control unit 113 can adjust the amount of total residual oxides remaining in the ballast water to be constant to meet the standard.

The ballast water treatment system of the present invention may further include a water vent 302 for discharging the ballast water flowing backward in case the ballast water flows backward through the ozone gas inflow line. This is because the ozone generator can be damaged if the backflowed ballast water enters the ozone generator.

The valve V43 is located between the drive water pump and the AP tank, and the valve 41 is located at the front end of the ballast pump P33.

For the purpose of understanding of the present invention, the operation when the vessel equipped with the vessel holding vessel equilibrium water treatment system is in operation in seawater and fresh water will be described in detail.

FIG. 6 and FIG. 7 are views for explaining that an apparatus for generating ultra-fine bubbles of ozone according to an embodiment of the present invention is mounted on a ballast water inflow main line.

6 and 7, the ozone ultrasonic bubble generator 200 is embedded with an ozone ultrasonic bubble generator in a ballast water inflow main line in the shape of a cylinder 211 in which the inside is empty so that the ballast water can flow .

The ozone ultra-fine bubble generator 200 includes a nozzle 240, an ozone gas inflow line 212 through which ozone gas flows, a protrusion 213, a fixing plate 215, and a water inflow line 217 .

The nozzle 240 is connected to the ozone gas inflow line 212 to receive ozone gas and is connected to the water inflow line 217 to receive water (seawater or nose water stored in the AP tank) (Hereinafter referred to as " ozone gas dissolving water ") is injected into the ballast water inflow main line to generate fine bubbles.

The ozone ultrasonic bubble generator 200 is installed in a part of the ballast water inflow main line L31 in a state in which the ballast water inflow main line L31 is mounted in a cylinder 211 having the same or similar shape and size as the ballast water inflow main line L31 . Here, the flanges F are connected to each other so as to connect the main line L31 and the cylinder 211 in which the ozone ultra-bubble generator 200 is mounted. The bin 211 in which the ozone ultra-fine bubble generator 200 is mounted is a part of the main line L31, and the bin 211 is distinguished only when there is a special advantage to be distinguished.

The internal structure and detailed operation of the nozzle 240 will be described later with reference to Figs. 8 to 11. Fig.

With continued reference to FIG. 6, a section in which a window 221 in which an interior is visible can be additionally disposed. The window 221 is an optional device for visually confirming whether ultra-fine bubbles have flowed well into the inside of the window 221 for convenience of management.

8 to 11 are views for explaining a nozzle according to an embodiment of the present invention.

Referring to these figures, the nozzle 240 includes a body 241, 243 and a collision portion 244, 246, 242.

The main body 241 and the collision portions 244, 246 and 242 are coupled to each other and the main body 241 and the collision portions 244, 246 and 242 are shown separated from each other for the sake of explanation.

The main body 241 has a cylindrical shape as a whole, and the chamber 243 surrounds a part of the main body 241 from the outside.

The main body 241 has a first flow path P1 connected to the water inflow line 217 to receive water and a second flow path S2 connected to the first flow path P1 and flowing out from the first flow path P1 A second flow path P2 for introducing the ozone gas from the ozone gas inflow line 212 and for discharging ozone gas dissolved water and a third flow path P2 for flowing the ozone gas dissolved water from the second flow path P2, And a flow path P3.

The ozone gas is introduced at or near the point where the first flow path P1 and the second flow path P2 meet. The chamber 243 surrounds a portion where the first flow path P1 and the second flow path P2 meet with each other and is connected to the ozone gas inflow pipe 212 to supply ozone gas flowing from the ozone gas inflow pipe 212 It can be saved temporarily.

The chamber 243 is formed with an opening 245 connected to the ozone gas inflow pipe 212. The ozone gas inflow pipe 212 may be inserted into the opening 245, for example, in a fitting manner.

The diameter of the first flow path P1 is smaller than that of the second flow path P2, which is connected to the water inflow line 217. That is, the diameter of the first flow path P1 becomes smaller as it gets closer to the second flow path P2 and the diameter of the second flow path P2 becomes smaller as it gets closer to the first flow path P1, (P3).

Since the pressure of the supplied water is greater than the pressure inside the ozone gas inflow line 212, the ozone gas in the ozone gas inflow line 212 naturally flows into the water inflow line. The relative diameters of the first flow path P1, the second flow path P2, and the third flow path P3 are as described above.

The collision portion includes an impact portion main body 249 which receives the ozone gas dissolved water flowing out of the third flow path P3, an annular ring 242 fitted in a fitting manner with the outflow end 248 of the main body 248, An impingement plate 244 which collides with the dissolved ozone gas flowing out from the outflow end 248 of the main body 249 and a support base 246 which fixes the impingement plate 244 in a state of being separated from the annular ring 242 .

The impingement plate 244 may be formed of, for example, a circular plate. The ozone gas dissolved water flowing out from the main body 249 collides with the impingement plate 244, and ultrafine bubbles are generated. The ultrafine bubbles generated while bumping into the collision plate 244 are directed to the inner wall surface of the ballast water inflow main line as shown in FIG.

By this impingement plate 244, the ultra-fine ozone bubbles can be uniformly sprayed over the entire area of the ballast main pipe.

FIG. 12 is a view for explaining a fine hole formed in the nozzle illustrated in FIGS. 8 to 10. FIG.

Referring to FIG. 12, the first flow path P1 or the second flow path P2 is connected to the chamber 243 through at least one fine hole 247. The ozone gas temporarily stored in the chamber 243 flows into the first flow path P1 or the second flow path P2 through at least one fine hole 247. [

The flow of the ballast water flowing through the first flow path P1 and the second flow path P2 is fast so that the ozone gas stored in the chamber 243 flows naturally into the first flow path P1 and the second flow path P2, And can flow into the flow path P2.
