Description

[0001] Hybrid ballast water treatment equipment [0002]

The present invention relates to a hybrid ship ballast water treatment apparatus, and more particularly, to a hybrid ballast water treatment apparatus which measures the salinity of an influent water used as a ballast water and treats it as electrolysis when it is determined as seawater by comparison with a reference salinity, The present invention relates to a hybrid ship ballast water treatment apparatus of an automatic system for treating a hybrid ship ballast water by a chemical method.

Generally, a large ship will store a certain amount of ballast water in ballast tanks for the purpose of balance of ships and safe navigation in the state that cargo is not loaded.

However, since the ballast water stored in the ballast water tank is taken from one area of the sea and discharged to the other area, it acts as a medium to move marine and disease-causing bacteria in one area to other areas, thereby destroying marine pollution and ecosystem Which is the main cause of death.

Therefore, in order to prevent marine pollution and destruction of ecosystem, disinfection and disinfection are carried out when seawater is taken into a ballast water tank in a local area. That is, when a ship is equipped with a ballast water treatment apparatus, the seawater is sterilized and disinfected when the seawater is taken in a ballast tank, thereby preventing marine pollution and destruction of ecosystems. Such marine ballast water treatment apparatus is a structure for electrolyzing seawater flowing along an inflow pipe with an electrolytic apparatus to sterilize and disinfect the marine equipments.

On the other hand, there are cases where the ship is going to the area where the canal develops or passing through. In this case, seawater may be used as ballast water or fresh water may be used. However, the conventional ballast water treatment system is structured by limiting the ballast water to seawater or freshwater, and there is a structural limitation that both seawater and fresh water can not be used as ballast water.

Therefore, in ships using sea water and fresh water as equilibrium water, the first line for treating seawater and the second line for treating fresh water are separately provided and the operator manually distinguishes between using seawater and fresh water, It is inconvenient and inefficient to open and close the line and the second line.

In order to solve such a problem, it is necessary to develop a ballast water treatment apparatus capable of sterilizing and disinfecting seawater and fresh water by separating seawater and fresh water without manual operation of the operator and using it as ballast water.

Therefore, it is possible to use seawater and fresh water as equilibrium water very easily, by separating the treatment of seawater and fresh water by an automatic method by salinity measurement and discrimination without operator's operation.

Hereinafter, a hybrid ship ballast water treatment apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1, a hybrid ship ballast water treatment apparatus according to a preferred embodiment of the present invention includes an inlet pipe 10, a pump 20, a salinity sensor 30, a controller 40, a treatment pipe 50, An electrolytic bath 60 and a medicine sprayer 70. [

First, the inflow pipe 10 is a pipe through which inflow water to be used as ballast water flows. At this time, influent water can be seawater and fresh water depending on the location where the ship is anchored.

Next, the pump 20 is configured to inflow the influent water through the inflow pipe 10 and feed the inflow water to the ballast water tank. At this time, the pump 20 is installed on the inflow pipe 10 and has a capacity corresponding to the ballast water tank.

On the other hand, on the inflow pipe 10, as shown in FIG. 1, a pretreatment filter 80 for partially removing organisms contained in the inflow water is installed. However, the pretreatment filter 80 may be installed at the front end of the pump 20 or at the rear end of the pump 20.

The pretreatment filter 80 primarily functions to kill a part of the organisms included in the influent water in order to increase the treatment efficiency of the electrolytic bath 60 or the medicine sprayer 70 to be described later.

As shown in FIG. 4, the blade 83 has a plurality of rotating blades 831 formed by perforating a plurality of filtration holes 832 at a predetermined interval, A plurality of units are installed in multiple stages. In other words, the blade 83 physically rotates the organism included in the influent water as the inflow water passes through the filtration hole 832 while the rotary vane 831 rotates naturally by the flow of the inflow water.

Next, the salinity sensor 30 measures the salinity of the influent water flowing into the ballast water tank through the inflow pipe 10 according to the operation of the pump 20.

That is, the salinity sensor 30 measures the salinity which is a criterion for separating the seawater and the fresh water so that the inflow water flowing through the inflow pipe 10 can be discriminated whether the inflow water is seawater or fresh water.

Accordingly, if the saltiness value of the influent water measured by the salinity sensor 30 is transmitted to the controller 40 to be described later, the controller 40 determines whether the influent water is seawater or fresh water, and generates a corresponding control signal.

Next, the controller 40 determines whether the inflow water flowing through the inflow pipe 10 is seawater or fresh water based on the salinity of the inflow water measured by the salinity sensor 30, And the operation of the medicine sprayer 70 are controlled.

That is, the controller 40 generates a first control signal for determining the seawater when the salinity of the influent water is greater than or equal to the reference salinity, and generates a second control signal for determining the salinity if the salinity is less than the reference salinity.

[0064]

Next, the electrolytic bath 60 is provided on the treatment pipe 50 and electrolytically dissolves the organisms and bacteria contained in the seawater passing along the treatment pipe 50.

At this time, the electrolytic bath 60 is automatically operated according to the first control signal of the controller 40. That is, the electrolytic bath 60 operates only when the influent water is determined to be seawater under the control of the controller 40.

However, when the treatment pipe 50 is composed of two, the electrolytic bath 60 is installed on the first treatment pipe 51. The electrolytic bath 60 may have a multi-stage structure on the treatment piping 50 in order to increase the treatment efficiency with respect to seawater.

Finally, the chemical sprayer 70 is constructed on the treatment pipe 50 to kill the organisms and bacteria contained in the fresh water passing along the treatment pipe 50 with the chemical medicine.

At this time, the medicine injector 70 is automatically operated in accordance with the second control signal of the controller 40. That is, the medicine injector 70 operates only when the influent water is determined to be fresh water under the control of the controller 40.

However, when the treatment piping 50 is composed of two, the chemical spraying device 70 is installed on the second treatment piping 52.
