Description

[0001] Ballast water treatment apparatus [0002]

The present invention relates to a ballast water treatment apparatus, and more particularly, to a ballast water treatment apparatus which collects sterilization degree required in various parts of a ship and produces a sterilizing agent of an appropriate concentration or a proper amount according to the collected sterilization degree, To a ballast water treatment apparatus.

The restoring force of the ship is determined by the interaction of gravity and buoyancy acting on the ship. If the ship is not tilted, gravity and buoyancy are present on the same line of action, and no force is generated. However, when the ship is tilted, gravity and buoyancy are present on different lines of action, resulting in a combined force of gravity and buoyancy, .

Here, the gravity is determined by the weight of the ship, and the buoyancy is determined by the volume of the ship submerged in seawater. In order to improve the restoring force, it is preferable to increase the buoyancy by increasing the volume of the ship submerged in seawater.

On the other hand, in the case of a ship carrying cargo, the volume of the ship submerged in seawater may be changed as the weight of the cargo is changed or the cargo is loaded or unloaded. In order to compensate for this, the ship may be equipped with a ballast water treatment system .

The ballast water treatment system is a system that recovers seawater to raise the weight of the ship or recover the weight of the ship by releasing the incoming seawater. For example, if the cargo is unloaded, the ballast water treatment system can increase the weight of the ship by introducing seawater, and if the cargo is loaded, the ballast water treatment system can reduce the weight of the ship by releasing seawater. In this way, as the seawater is introduced or discharged depending on the situation, the total weight of the ship can be maintained to be optimum, and a sufficient restoring force can be secured.

In this way, the restoration power of the ship can be ensured by the inflow and outflow of seawater by the ballast water treatment system. Although the inflow and outflow of seawater can be performed in the same place, have. There are various microorganisms in seawater, and the types of microorganisms may be different in each sea water. When seawater is introduced into a different sea water from a certain sea water, seawater may be contaminated by mixing different microorganisms.

In order to prevent this, a ballast water treatment system is provided with a filter for preventing inflow of microorganisms, and a sterilizing agent may be used for destroying microorganisms not filtered by the filter. That is, by injecting the microbicide into the inflowed seawater, microbes remaining in the stored seawater are destroyed.

The release of seawater containing residual fungicide can result in environmental or economic damage, such as the death of native species present in the area. The ballast water treatment system can then release seawater after removing the fungicide component have.

On the other hand, a sterilizing agent may be required in various parts of the ship, but it is difficult to provide a sterilizing agent supply unit for each part.

Not only is it expensive to install a sanitizer supply, but it also requires space for installation.

Therefore, the emergence of an invention for supplying the necessary sterilizing agent in various parts of a ship is required.

Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

1 is a view showing a ballast water treatment apparatus according to an embodiment of the present invention.

The ballast water treatment apparatus 10 includes a ballast pump 11, a filter 12, an electrolytic tank 13, a ballast tank 14, a neutralization unit 15, a sterilizing agent management unit 18 and a sterilizing agent storage tank 19 .

The ballast pump 11 generates a pressure difference and serves to introduce seawater outside the ship into the inside of the ship. The seawater is introduced into the ship through the sea chest 20 by the pressure of the ballast pump 11. The seed chest 20 is provided at a lower portion of the ship to temporarily store the seawater. A strainer may be provided to prevent foreign matter from entering the ship.

The seawater flowing through the seed chest 20 may contain various microorganisms. The filter 12 plays a role of preventing inflow of microorganisms. The filter 12 may be configured to include an element that performs filtering, as the filtering proceeds, the filtered microorganisms remain in the element and thus the effect of inflow of seawater may be reduced.

This is accompanied by an operation of cleaning the element to remove the microorganisms remaining in the element, and when the filter 12 is configured to include a plurality of elements, some of the elements may be subjected to cleaning Work can proceed.

On the other hand, most of the microorganisms can be removed from the seawater introduced by the filter 12, but the microorganisms not filtered by the filter 12 remain in the seawater as they are.

These microorganisms can be destroyed by using a sterilizing liquid, and the electrolytic bath 13 can generate hypochlorous acid (HClO), which is a raw material of the sterilizing liquid. The electrolytic bath 13 electrolyzes a part of the incoming seawater to generate hypochlorous acid.

A part of the seawater filtered by the filter 12 flows into the electrolytic bath 13 and contacts the electrode in the electrolytic bath 13 to generate hypochlorous acid through chemical reaction and the seawater containing hypochlorous acid is again supplied to the main piping 360, Lt; / RTI > At this time, a TRO sensor 16 for measuring the TRO (Total Residual Oxidant) concentration of the seawater at the point where the hypochlorous acid is injected may be provided to generate a proper amount of hypochlorous acid.

The electrolytic bath 13 can electrolyze the seawater introduced through the seed chest 20 or electrolyze the separate seawater previously provided to generate a sterilizing agent.

The ballast tank 14 serves to receive the microbial depleted ballast water, and may be formed along the lower surface or along the lower surface and the side surface of the ship to lower the center of gravity of the ship.

1 shows one ballast tank 14, a plurality of ballast tanks may be arranged on the lower surface and the side surface of the ship, respectively.

As the hypochlorous acid generated by the electrolytic tank 13 is injected, the ballast water contained in the ballast tank 14 contains a sterilizing component, but the sterilizing component disappears over time.

However, if sufficient time has not elapsed, the ballast water may still contain germicidal components, which must be removed in discharging the ballast water contained in the ballast tank 14. This is because if the residual sterilization component is not removed, it may cause environmental damage that the native microorganisms in the water area are removed by the residual sterilizing component.

In order to neutralize the germicidal component, the neutralization unit 15 serves to inject neutralizing agent into the ballast water discharged from the ballast tank 14.

As described above, when hypochlorous acid generated by the electrolytic bath 13 is used as the bactericide, the neutralizing unit 15 can inject a neutralizing agent that reacts with chlorine components. For example, ascorbic acid (C6H8O6), sodium sulfite (Na2SO3), sodium hydrogen sulfite (NaHSO3), sodium bisulfite (NaHSO3), and sodium thiosulfate (Na2S2O3).

Meanwhile, TRO (Total Residual Oxidant) sensors 16 and 17 may be provided to inject a proper amount of neutralizing agent. The TRO sensors 16 and 17 measure the TRO concentration of the ballast water contained in the ballast tank 14 and the TRO concentration of the ballast water to which the neutralizer injected by the neutralization unit 15 is reflected The neutralization unit 15 may determine the amount or concentration of the neutralizing agent to be injected referring to the TRO concentration detected by the TRO sensors 16 and 17.

The fungicide management unit 18 receives the need for the germicide at the at least one fungicide demanding site present in the vessel and serves to supply the germicide generated by the electrolytic bath 13.

In addition to seawater flowing into the ballast tank 14, there is a place or apparatus that requires a sterilizing agent in the vessel, and the sterilizing agent management unit 18 manages the sterilizing agent so that the sterilizing agent is supplied to such place or apparatus.

The sterilizing agent storage tank 19 serves to store the sterilizing agent generated by the electrolytic bath 13.

The sterilizing agent management unit 18 manages the sterilizing agent generation by the electrolyzer 13 and the supply of the sterilizing agent contained in the sterilizing agent storage tank 19. The sterilizing agent management unit 18 controls the flow of seawater flowing into the electrolyzer 13, It is possible to control at least one of the flow of the sterilizing agent discharged from the tank 19 and the interlocking of the generation and supply of the sterilizing agent.

For example, the disinfectant management unit 18 can prevent the generation of the disinfectant by allowing the seawater to be supplied to the electrolytic bath 13, or the seawater supplied to the electrolytic bath 13 may be blocked.

In addition, the fungicide management unit 18 may control the pumps and valves provided in the piping connected to the at least one fungicide consumer in the fungicide storage tank 19 to supply the fungicide to the selected fungicide consumer.

For example, if the demand for disinfectant A and C requires a disinfectant in the presence of the disinfectant demanding sites A, B, C, and D, the disinfectant management unit 18 acquires the disinfectant from the disinfectant storage tank 19, So that the sterilizing agent can be supplied to the customer by opening the valve.

2 is a conceptual view showing the role of the fungicide management unit 18 according to the embodiment of the present invention.

There is a demand for a fungicide such as the seed chest 20, the wastewater treatment device 30, the water purifier 40, and the reusing water tank 50 on the ship.

Seed chests 20 may be contaminated with marine organisms such as barnacles or seashells, which may be used to prevent access to marine organisms or to remove marine organisms from the sea chest 20 .

A sterilizing agent is used for disinfecting the wastewater treatment device 30 and the reusing water tank 50 and a sterilizing agent is used for removing the microorganisms contained in the fresh water, .

Each bactericide demanding customer can send the sterilizing agent management unit 18 with information on whether the sterilizing agent needs or the necessary amount of sterilizing agent to the sterilizing agent management unit 18. The sterilizing agent management unit 18 then controls the electrolyzer 13 to control the generation of the sterilizing agent , And the fungicide can be supplied to the demand of the fungicide requiring the fungicide.

Alternatively, the user may input the desired amount and amount of the fungicide requiring the fungicide directly. The fungicide management part 18 controls the electrolytic bath 13 to control the generation of the fungicide based on the command input from the user, It is also possible to supply the fungicide to the demand of the fungicide.

3 is a view showing a supply path of the sterilizing agent according to an embodiment of the present invention.

The seawater filtered by the filter 12 is delivered to the ballast tank 14 along the main line 360. Some of the filtered seawater is delivered to the electrolytic bath 13 along the seawater inlet line 370, Lt; / RTI >

The seawater injection pipe 370 branched from the main pipe 360 and connected to the electrolytic bath 13 may be provided with a seawater injection pump 310 and a seawater injection valve 320. The sanitizer management unit 18 To control the inflow of seawater into the electrolytic bath (13) or to control the amount of sterilant produced by the electrolytic bath (13). In addition, the fungicide management unit 18 may directly control the concentration of the fungicide generated by transmitting the control command to the electrolytic bath 13.

The sterilizing agent produced by the electrolytic bath 13 is stored in the sterilizing agent storage tank 19. The sterilizer management unit 18 can cause the electrolyzer 13 to generate a sterilizing agent when not only when a signal indicating that a sterilizing agent is needed but also when it is not so and the sterilizing agent thus generated can be stored in the sterilizing agent storage tank 19 It is.

The sterilizing agent management unit 18 may control whether the sterilizing agent is generated by the electrolytic bath 13 in consideration of the amount of the sterilizing agent stored in the sterilizing agent storage tank 19.

The sanitizer storage tank 19 is connected to the main pipe 360 by a first supply pipe 381 and a second supply pipe 382. The first supply pipe 381 is a pipe for supplying a sterilizing agent to seawater supplied to the ballast tank 14. The first supply pipe 381 is provided with a first supply valve 341, 1 supply pump 331 and a first supply valve 343 may be provided.

The second supply pipe 382 is connected to the sterilizing agent injection pipe 390 to supply the sterilizing agent to the consumer with the second supply pipe 342 and the second supply pipe 382 to control the flow of the sterilizing agent. A second supply pump 332 and a second supply valve 344 may be provided.

The second supply pipe 382 is also connected to the main pipe 360 so that the sterilizing agent supplied through the second supply pipe 382 can be transferred to the ballast tank 14 as well as to the fungicide consumer. A sterilizing agent injection valve 351 may be provided in the second supply piping 382 to control the flow of sterilizing agent flowing from the second supply piping 382 to the main piping 360.

The sterilizing agent injection pipe 390 is branched and connected to the demand of each sterilizing agent. In order to control the flow of the sterilizing agent to each bactericide supply source, injection valves 352, 353, 354, and 355 are connected to the branch pipes 391, 392, 393, May be provided.

The sterilizing agent management unit 18 is connected to the pumps 310, 331 and 332 and the valves 320, 341, 342, 343, 344, 351 and 352 provided in the respective pipes 370, 381, 382, 391, 392, 393 and 394 , 353, 354, 355) to control the supply of seawater and germicide.

4 and 5 are diagrams showing that the disinfectant according to the embodiment of the present invention is supplied to the demand of the disinfectant, FIG. 4 is a view showing the simultaneous production and supply of the disinfectant, Fig.

Some of the seawater filtered by the filter 12 is transferred to the electrolytic bath 13 along the seawater inlet piping 370 branched from the main pipeline 360. Thus, the electrolytic bath 13 electrolyzes the transferred seawater to generate a sterilizing agent.

The sterilizing agent generated by the electrolytic bath 13 is stored in the sterilizing agent storage tank 19 and the stored sterilizing agent is moved along the first supply piping 381 and injected into the main piping 360. Thus, the sterilizing agent can be injected into the seawater supplied from the filter 12 to the ballast tank 14.

At this time, the fungicide management unit 18 may receive a request for supplying the fungicide to the consumer of the fungicide provided on the ship. The disinfectant supply request may be received from a fungicide consumer and entered from a user.

Fig. 4 shows that a sterilizing agent supply request for the wastewater treatment device 30 is received.

The sterilizing agent management section 18 operates the second supply pump 332 provided in the second supply pipe 382 and the second supply valve 342 and the second supply valve 342 are operated in response to receiving the sterilizing agent supply request to the wastewater treatment device 30, The sterilizing agent contained in the sterilizing agent storage tank 19 is supplied to the wastewater treatment device 30 by opening the second supply valve 344 and opening the second injection valve 353 provided in the second branch pipe 392 do.

As described above, while the sterilizing agent is generated by the electrolytic bath 13, the supply to the ballast tank 14 and the wastewater treatment device 30 can be performed simultaneously.

In addition, when a request for supplying a sterilizing agent to a plurality of bactericide demanding sites is received, the sterilizing agent managing unit 18 may control the corresponding plurality of valves to be opened so that the sterilizing agent is supplied to a plurality of bactericide demanding sites.

Figure 5 shows that only the supply of bactericides to the consumer is achieved without the production of bactericides.

Thus, the sterilizing agent supply to the wastewater treatment device 30 can be performed without generating the sterilizing agent by the electrolytic bath 13. This is because the previously generated sterilizing agent is accommodated in the sterilizing agent storage tank 19. For this purpose, the sterilizing agent management unit 18 senses the amount of the sterilizing agent previously stored in the sterilizing agent storage tank 19, 13) to produce a bactericide.
