Description

FIELD OF THE INVENTION [0001] The present invention relates to an ultraviolet and chlorine combination ballast water treatment apparatus,

The present invention relates to an ultraviolet and chlorine combination ballast water treatment apparatus for treating a ballast water of a ship.

The ship is operated in a ballast tank containing seawater in order to improve the efficiency of operation and balance and stability of the propeller and rudder in the water when the cargo is not sufficient, It is called ballast water.

Ballast water is a heavy material that is loaded to control the balance and draft of the ship, and functions to enhance balance and stability of the ship. The ballast can perform auxiliary functions to ensure that the propeller and rudder operate effectively in the water when the cargo is not fully loaded. Depending on the ship, ballast water or sand may be used as equilibrium instead of loading ballast water, but today, it is common to use sea water or fresh water as equilibrium.

The biggest problem of ballast water is basically that ballast water is used as a medium to propagate foreign marine species. That is, if a creature or pathogen in a specific sea area contained in equilibrium water is completely different by a vessel containing ballast water And it is transferred to the sea area, causing the side effect of disturbing the environment and the ecosystem of the sea area. The problems that arise from the transboundary movement of species in these equilibrium will cause not only the ecosystem disturbance but also the coastal industry and other commercial activities or resources.

For example, when a ship located in a first area is operated to ship a cargo located in a second area, the ship can control the amount of ballast water by storing fluid such as seawater, fresh water, etc. located in the first area in the ballast tank have. When the ship reaches the second area, the ship can control the amount of ballast water by discharging the ballast water stored in the ballast tank to the outside according to the amount of cargo loaded.

When the ballast water stored in the ballast tank is discharged from the second region, the inorganic matter such as gravel, sand, clay, and the like living in the first region, organisms such as crustaceans, plankton, Mixture ') is moved to the second area, it causes damage such as ecosystem disturbance and harmful pathogen spreading.

Therefore, it is necessary to develop a device for treating ballast water, since a vessel for remote navigation is required to install a device capable of removing foreign matters such as minerals, organisms, and organic substances contained in ballast water. to be.

In this case, the filter element 111 may be installed in the filter housing 110 to filter the mixture contained in the equilibrium water. The ultraviolet ray irradiating unit 120 irradiates ultraviolet rays to the ballast water filtered by the filter element 111. Accordingly, the ultraviolet ray irradiating unit 120 can sterilize the ballast water. The chlorin disinfection unit 140 disinfects the ultraviolet-treated ballast water using the chlorine disinfectant containing the chlorine component.

Therefore, the apparatus 100 for treating ultraviolet ray and chlorine combined ballast water according to the present invention, as compared with the case of disinfecting the ballast water using electrolysis or the like, omits a member facility for discharging hydrogen by using the electrolytic apparatus . Accordingly, the ultraviolet and chlorine combined ballast water treatment apparatus 100 according to the present invention can reduce the cost required for equipments for treating the ballast water.

Hereinafter, the filter housing 110, ultraviolet ray irradiation unit 120, and chlorine disinfection unit 140 will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the filter housing 110 introduces or discharges ballast water. The filter element (111) is installed inside the filter housing (110). The filter housing 110 may be connected to the ultraviolet ray irradiating unit 120. In this case, the filter housing 110 can supply the ultraviolet ray irradiating unit 120 with the ballast water filtered by the filter element 111. The filter housing 110 has an inlet 112 for introducing the ballast water to one side thereof and an outlet 113 for discharging the ballast water to the other side thereof.

The filter element 111 is installed in the filter housing 110 to filter the mixture contained in the equilibrium water during the movement of the ballast water from the inlet 112 to the outlet 113. For example, the filter element 111 may be provided with a through hole 1111 for filtering water. In this case, the filter element 111 can filter the equilibrium water by allowing the mixture contained in the equilibrium water to adsorb to the periphery of the through-hole 1111 and to pass the equilibrium water.

The inflow portion 112 may introduce the ballast water into the filter housing 110. For example, the inflow portion 112 may introduce the ballast water into the filter housing 110 by a pump.

The outlet 113 allows the filtered water filtered by the filter element 111 to flow out of the filter housing 110. For example, the outflow portion 113 may allow the filtered ballast water to flow out from the filter housing 110 to the ultraviolet ray irradiating portion 120. In this case, the outflow portion 113 may allow the ballast water to flow out to the ultraviolet ray irradiating portion 120 through the first pipe P ₁ connected to the ultraviolet ray irradiating portion 120.

Therefore, the apparatus 100 for treating ultraviolet ray and chlorine combined ballast water according to the present invention can prevent the mixture from propagating between the first region and the second region during operation of the ship. Accordingly, the apparatus 100 for treating ultraviolet and chlorine combined ballast water according to the present invention can prevent the marine ecosystem from being disturbed by the mixture and further reduce the damage to the coastal industry, marine commercial activities and marine resources .

Here, the filter element 111 may be less efficient in filtering the ballast water by the mixture adsorbed in the through holes 1111. To prevent this, a filter cleaning unit 114 is coupled to the lower end of the filter housing 110.

The filter cleaning unit 114 cleans the mixture adsorbed to the filter element 111 by sucking the ballast water in a direction toward the filter element 111. In this case, the mixture washed by the filter cleaning unit 114 may be discharged through the discharge unit 1141 connected to the filter cleaning unit 114. Accordingly, the ultraviolet and chlorine combined ballast water treatment apparatus 100 according to the present invention can prevent the through hole 1111 from being clogged by removing the mixture remaining in the filter element 111. Accordingly, the ultraviolet and chlorine combined ballast water treatment apparatus 100 according to the present invention can improve the efficiency of the operation of filtering the ballast water.

The ultraviolet ray irradiating unit 120 can ultraviolet rays the ballast water by irradiating ultraviolet rays to the ballast water filtered by the filter element 111. To this end, the ultraviolet ray irradiating unit 120 may be connected to the filter housing 110 by the first pipe P ₁ . Here, when the sterilizing process is performed by the ultraviolet ray irradiating unit 120, the ultraviolet ray irradiating unit 120 may block the inflow of the ballast water by using the first valve V ₁ installed in the first pipe P ₁ have. In addition, the ultraviolet ray irradiating unit 120 may move the ballast water to the chlorination unit 140 through the second pipe P ₂ after the sterilization process for the ballast water is completed. The ultraviolet ray and chlorine combined ballast water treatment apparatus 100 according to the present invention sterilizes the ballast water by irradiating ultraviolet rays to the ballast water filtered by the filter element 111, The unfiltered mixture can be removed. Accordingly, the ultraviolet and chlorine combined ballast water treatment apparatus 100 according to the present invention can prevent the mixture from propagating between the first region and the second region. Accordingly, the apparatus 100 for treating ultraviolet and chlorine combined ballast water according to the present invention not only can prevent disturbance of the marine ecosystem, but also contributes to reduce damage to the coastal industry, marine commercial activities and marine resources .
