Description

[0001] The present invention relates to a neutralizing agent generation apparatus,

The present invention relates to a neutralizing agent generating apparatus, and more particularly, to a neutralizing agent generating apparatus for generating a liquid neutralizing agent by generating movement in a neutralizing agent solvent into which a solid neutralizing agent is introduced.

The resilience of the ship is determined by the combination 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 when the cargo is loaded, it can reduce the weight of the ship by discharging seawater to the ballast water treatment system. 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 the microorganisms not filtered by the filter. That is, by injecting the microbicide into the inflowed seawater, microbes remaining in the stored seawater are destroyed.

However, in case of releasing the stored sea water, if the residual bactericide is contained in the sea water, it causes environmental and economic damages such as causing the native species already existing in the water body to be killed, Releases seawater after removing components.

Here, a neutralizing agent may be used to remove the disinfectant component. The neutralizing agent having a neutralizing function is a solid, but it must be applied in the form of an aqueous solution upon neutralization. Therefore, when a neutralizer is applied on a ship, a neutralizer already prepared in the liquid phase on the land or a solid neutralizer can be shipped and produced in a liquid form on board.

The use of a neutralizer already prepared in liquid form on the land has the advantage that it can be directly applied to seawater to be discharged without going through a separate processing procedure. However, it is difficult to universally obtain neutralizer of the same concentration in the ports of the world, The disadvantage is that it requires the manpower of the crew to be shipped and refilled in the neutralizer tank at the time of purchase, which can be troublesome.

On the contrary, the solid neutralizing agent is applied to the seawater after liquefaction. It has an advantage that it can be appropriately produced only as needed and is easy to store. For this reason, a solid neutralizing agent is used in many cases, but it takes a long time to liquefy the solid neutralizing agent, and a rotary device such as an agitator should be provided as a device for liquefaction. In addition, the equipment is required to be periodically maintained as a rotating machine, and if the maintenance is not performed, there is a disadvantage that frequent failures may result in loss of function.

In this case, even though seawater should be discharged in order to secure the balance of the ship, the generation of the neutralizing solution may be delayed or incapable of discharging the seawater, so that it may not be possible to load the cargo when necessary.

Therefore, there is a need for an apparatus for producing a neutralizing agent using simple equipment for liquefying a solid neutralizing agent in a short period of time.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

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

The ballast water treatment system 10 comprises a ballast pump 11, a filter 12, a ballast water treatment device 13, a ballast tank 14 and a neutralization device 15.

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.

Such fine microorganisms can be destroyed by using a sterilizing liquid, and the ballast water treatment apparatus 13 can generate hypochlorous acid (HClO), which is a raw material of the sterilizing liquid. The ballast water treatment device 13 generates a hypochlorous acid by electrolyzing a part of the incoming seawater.

A part of the seawater filtered by the filter 12 flows into the ballast water treatment device 13 and is brought into contact with an electrode in the ballast water treatment device 13 to generate hypochlorous acid through a chemical reaction and seawater containing hypochlorous acid And then injected into the main pipe again. 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.

It has been described above that the ballast water treatment device 13 for generating the sterilizing liquid through electrolysis performs the role of the sterilizing device, but all the ballast water treatment devices using ozone or the like may serve as the sterilizing device .

The ballast tank 14 serves to receive the microbial depleted ballast water, and is preferably formed along the lower surface or along the lower surface and the side surface of the ship in order 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 ballast water treatment device 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 sterilizing component, the neutralizer 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 ballast water treatment device 13 is used as the bactericide, the neutralization device 15 can inject a neutralizing agent that reacts with the chlorine component, for example, ascorbic acid (C6H8O6) , Sodium nitrate (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 reflected by the neutralizer 15 injected by the neutralizer 15 The neutralizer 15 may determine the amount or concentration of the neutralizing agent injected referring to the TRO concentration detected by the TRO sensors 16 and 17.

The neutralizing agent can be classified into a solid neutralizing agent and a liquid neutralizing agent. The liquid neutralizing agent has an advantage that it can be directly applied to the seawater to be discharged. On the other hand, it is difficult to universally acquire the neutralizing agent having the same concentration in the ports of the world. There is a disadvantage in that it requires the manpower of the crew to be loaded and refilled in the neutralizer tank, which can be troublesome.

The solid neutralizer is applied to the seawater after liquefaction. It has the advantage of producing as much neutralizing agent as needed and the advantage of easy storage. On the other hand, it is necessary to equip the liquefaction device with a rotating device such as a stirrer separately. The equipment is a rotating machine that requires periodic maintenance, and if maintenance is not carried out, there is a disadvantage that frequent failures can lead to loss of function. In addition, when an endothermic reaction occurs during dissolution like sodium thiosulfate, it takes a long time to liquefy the solid neutralizing agent.

The neutralization apparatus 15 according to the embodiment of the present invention may use a fluid to shorten the time required to liquefy the solid neutralizing agent. The solid neutralizing agent is injected into the neutralizing agent solvent which is the basis of the neutralizing agent solution, and the neutralizing agent solvent is sprayed with the fluid to cause the movement of the neutralizing agent solvent so that the solid neutralizing agent and the neutralizing agent solvent can be mixed more effectively.

2 is a view showing a neutralizing agent producing apparatus according to an embodiment of the present invention. The neutralizing agent production apparatus 200 may be built in the neutralization apparatus 15 or may be the neutralization apparatus 15 itself.

The neutralizer generating apparatus 200 includes a storage container 210, a neutralizer inlet 220, a solvent supplier 230, a fluid supplier 240, a vent 250 and a drain 270.

The storage container 210 serves to receive the neutralizing agent. Specifically, it is understood that the storage container 210 plays a role of receiving the neutralizing agent solvent that is the basis of the neutralizing agent solution. The neutralizing agent in the present invention includes, but is not limited to, fresh water.

2 shows a cylindrical storage container 210, but there is no limitation in its form. However, in order to facilitate the release of the remaining neutralizing agent solution, it is preferable that the height of a specific point in the bottom of the storage container 210 is formed to be lower than the height of other portions, and a drain port 270 is provided at the point .

The neutralizer inlet 220 provides a path for the introduction of the solid neutralizer. The user can inject the solid neutralizing agent into the storage container 210 through the neutralizer inlet 220.

2 illustrates that the neutralizer inlet 220 is provided on the upper portion of the storage container 210, but it may be provided on the side surface of the storage container 210 as well. When the neutralizer inlet 220 is provided on the side surface of the storage container 210, it is preferable that the neutralizer inlet 220 is formed at a position higher than the water surface of the neutralizer solution to be produced.

The neutralizer inlet 220 is provided with a cover (not shown) to prevent the outflow of fly ash generated during the production of the neutralizer solution.

The solvent supply part 230 provides a path for introducing the neutralizing agent solvent. The user can supply the solvent of the neutralizing agent to the interior of the storage container 210 through the solvent supply unit 230. As described above, in the present invention, the neutralizing agent may be clean water, and fresh water may be supplied to the interior of the storage container 210 by connecting a separate fresh water pipe (not shown) to the solvent supply unit 230.

The fluid supply part 240 serves to inject fluid to the neutralizing agent. Specifically, the fluid supply unit 240 may act to generate a motion by the neutralizing agent solvent by spraying the fluid to the neutralizing agent solvent. For example, when a fluid having a velocity greater than a predetermined magnitude is ejected from the end of the fluid supply part 240 immersed in the neutralizing agent, the neutralizing agent moves by the force of the fluid or by the bubbles.

The solid neutralizing agent contained in the neutralizing agent solvent and the neutralizing agent solvent are mixed with the neutralizing agent solution by the movement of the neutralizing agent solvent and the possibility of effective collision between the solid neutralizing agent which is the neutralizing agent solute and the neutralizing agent solvent is increased , So that the liquefaction of the solid neutralizing agent can proceed more quickly.

Fluids in the present invention include, but are not limited to, oxygen or air, and are free of any kind of fluid to the extent that they do not modify the properties of the mixture.

The fluid can be supplied to the interior of the storage container 210 by connecting a separate fluid pipe to the fluid supply part 240. In order to supply a sufficient amount of fluid as shown in Figs. 4 to 8, Or the air compressor (not shown) may be connected to the fluid supply unit 240. The fluid supply unit 240 may be connected to the fluid supply unit 240,

The ventilation port 250 is formed in the storage container 210 and discharges the gas generated in the storage container 210 to the outside. The fluid injected by the fluid supply part 240 and the neutralizing agent solution are generated to generate the incidental gas, and the ventilation hole 250 serves to discharge the gas to the outside.

2 and 3, the neutralizer discharging unit 260 includes a neutralizer discharging unit 260 for discharging the generated neutralizing agent solution to the outside, A pump 261, a strainer 262, a pump 263, and an inlet.

The pump 263 generates a pressure difference to generate a force for discharging the neutralizing agent solution in the storage container 210 to the outside.

The neutralizing agent solution is sucked through the inlet portion and flows out along the neutralizer pipe 261. The inlet portion may be a foot valve or a check valve. The foot valve or the check valve provides the effect of preventing the fluid from flowing in only one direction and preventing backflow. Accordingly, when the pump 263 is operated, a pressure difference is generated and the inside of the inflow portion is opened, The neutralizing agent solution may be discharged to the outside along the neutralizer pipe 261. However, if the pump 263 is not operated, the inside of the inlet portion is closed so that the neutralizing agent solution of the storage container 210 is not discharged to the outside, It is possible to prevent the fluid outside the storage container 210 from flowing into the storage container 210.

The strainer 262 serves to filter out the foreign substances contained in the neutralizing agent solution so as not to be discharged to the outside. The solid neutralizing agent may be added to the storage container 210, and the solid neutralizing agent itself may be manufactured by including the foreign material. The strainer 262 may be provided to release only the pure neutralizing agent solution.

The drain port 270 is formed below the storage container 210 and discharges the neutralizing agent solution and foreign matter. The storage container 210 according to an embodiment of the present invention is formed such that the height of a specific point of its bottom area is lower than the height of other parts and the drain hole 270 is provided at the corresponding point. So that the emission can be performed more effectively.

FIG. 3 is a diagram illustrating the introduction of a solid neutralizing agent into a neutralizing agent generating apparatus according to an embodiment of the present invention. The user can input the solid neutralizing agent 400 through the neutralizing agent inlet 220.

The injected solid neutralizing agent 400 may float on the neutralizing agent solvent 300 or sink on the lower surface of the storage vessel 210.

3 illustrates the interior of the storage container 210. The fluid container 241 includes a fluid pipe 241 providing a fluid path for fluid flow, And a fluid supply part 240 composed of a nozzle 242. As the fluid is injected through the injection nozzle 242, the fluid can be injected at a higher magnitude of pressure.

3 shows that the neutralizing agent discharging part 260 is provided with the inlet part at the end thereof, and a detailed description thereof has been described above, so it will not be described here.

3 shows that the bottom of the storage container 210 has the form of a funnel and the drain port 270 is provided at the lowest point, so that the release of the neutralizing agent solution and foreign matter is performed more easily .

FIG. 4 is a view showing a neutralizing agent generating apparatus according to an embodiment of the present invention ejecting a fluid.

As the injection nozzle 242 is completely immersed in the neutralizing agent solvent 300, a force acts on the neutralizing agent solvent 300 as the fluid is sprayed, and the bubbles 600 are generated by the fluid.

The possibility of effective collision between the neutralizing agent solvent 300 and the solid neutralizing agent 400 due to the movement of the neutralizing agent 300 and the bubbles 600 is increased and the generation of the neutralizing agent solution can be performed more quickly.

5 to 7 are views showing that the neutralizing agent 300 is convected as the neutralizing agent generating apparatus according to the embodiment of the present invention injects the fluid, And the neutralizing agent 300 is convection.

As shown in FIG. 5, when a fluid is sprayed in a horizontal direction from one side of the lower part of the storage container 210, one circular convection is formed across both sides of the storage container 210, A plurality of circular convections having different rotational directions are formed when the fluid is sprayed upward from the lower center of the rotor 210.

The solid neutralizing agent 400 having a higher density than the neutralizing agent solvent 300 sinks in the lower portion of the storage container 210. In this case, the solidifying agent 400 and the neutralizing agent 300 And the solid neutralizing agent 400 having a smaller density than the neutralizing agent solvent 300 floats on the neutralizing agent solvent 300. In this case, the solid neutralizing agent 400, which forms the convection as shown in FIG. 6, And the neutralizing agent (300).

Accordingly, a fluid supply part 240 that forms different forms of convection depending on the properties of the solid neutralizing agent 400 can be used.

In addition, as shown in FIG. 7, a plurality of injection nozzles 242 may be provided in the fluid pipe 241. In this case, by generating a larger pressure, the time for generating the neutralizing agent solution can be further shortened.

8 is a diagram illustrating a heat exchanger according to an embodiment of the present invention for heating a fluid.

The temperature can be an important factor in mixing a solvent and a solute to produce a solution. In most cases, the higher the temperature, the faster the solution is produced.

On the other hand, when the solid neutralizing agent (400) is mixed with fresh water, the temperature of the mixture may be lowered by an endothermic reaction.

In order to prevent this, the fluid supply part 240 according to the embodiment of the present invention may inject the heated fluid to the neutralizing agent solvent 300.

The temperature of the mixture can be increased by injecting the heated fluid, and the rate of solution generation can be improved by compensating for the temperature as dropped by the endothermic reaction.

A heat exchanger 800 may be provided to heat the fluid, and the heat exchanger 800 performs heat exchange with the fluid to provide the heated fluid to the fluid supply unit 240.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
