Description

FIELD OF THE INVENTION [0001] The present invention relates to a ballast water management system and method for treating ballast water using heating and high frequency,

The present invention relates to a ship ballast water treatment apparatus, and more particularly, to an apparatus and method for treating ship ballast water using heating and high frequency.

In general, a method of using filtration and electrolysis for treating ship equilibrium water has been known. For example, Korean Patent Laid-Open No. 10-2015-0005240 (Ship Ballast Water Treatment System), Korean Patent No. 10-1445250 Automatic washing type ship ballast water treatment apparatus).

However, the existing technology has a disadvantage that it must be filtered only at the place where the ballast water is introduced when discharging it through backwashing because there is no means to sterilize the filtered aquatic organisms. In order to sterilize aquatic organisms by electrolysis, a high concentration of sodium hypochlorite must be produced. Therefore, when the ballast water is discharged, it must be neutralized with sodium thiosulfate or the like.

The present invention has been devised to solve the above-mentioned problems, and it is an object of the present invention to provide a ballast water treatment apparatus for treating a marine organism that has been filtered, sterilized and discharged, and treated with bacteria, bacteria, The present invention is directed to a ship ballast water treatment apparatus and method therefor.

It is an object of the present invention to provide a ship ballast water treatment apparatus using heating and high-frequency waves, comprising: a pipe pipe connected to the ballast water flowing in the apparatus along the oil passage so as to pass the ballast water in the forward direction or the reverse direction; A valve for regulating the water flow of the piping pipe; A filter unit for filtering aquatic organisms in the ballast water; An internal compartment separated by a filter unit; A heater unit for sterilizing the filter unit by heating the filtered aquatic organisms together with water; An electrolytic bath unit for treating bacteria, bacteria, and the like by discharging in water under high frequency; A pressure sensor for sensing a pressure difference in each of the inner compartments divided into filter units; A temperature sensor for sensing the temperature of the water heated by the heater unit; And a device housing.

Preferably, the filter unit further includes a filter alarm for limiting the operation of the device when the filter unit is damaged and the pressure difference in each of the internal compartments is lost or excessively varied.

It is preferable that the heater unit further includes a heater alarm for limiting the operation of the apparatus and generating a warning sound when the temperature of the heater unit is not detected due to damage to the temperature sensor.

It is preferable that the electrolytic bath unit further includes an electrolytic water surface view which restricts the operation of the electrolytic bath unit and generates an alarm sound when the electrolytic bath unit is damaged and the voltage exceeds the set reference value or below the reference value.

On the other hand, in the method of treating a ship ballast water using heating and high frequency waves, a ballast water flows in a positive direction by operating a valve, so that a living organism into which water flows is filtered and collected by aquatic organisms through a filter unit, Lt; / RTI > bacteria and bacteria; When the pressure difference in each of the inner compartments becomes equal to or greater than the set reference value or when the ballast water discharge is stopped by the operator, the valves are closed to prevent water from flowing, and then the heater unit is operated to heat the apparatus to the set temperature, Killing the aquatic organisms captured therein; After the aquatic organisms have been killed, the valve is operated to flow the ballast water in the reverse direction, and the aquatic organisms are collected through the filter unit in the inner compartment where the water is again introduced, and the aquatic organisms killed in the previous step are discharged together with the ballast water Treating the bacteria and bacteria through the electrolytic bath unit using a high frequency power source; Then, when the pressure difference in each of the inner compartments exceeds the set reference value or when the ballast water discharge is stopped by the user, the valves are closed to prevent water from flowing, and then the heater unit is operated to heat the apparatus to the set temperature, And a step of killing the aquatic organisms captured inside is repeated.

The present invention eliminates the need to operate the equilibrium water treatment apparatus when the ship is unloading cargo (i.e., when introducing the ballast water) because the ballast water is discharged when the vessel discharges the ballast water, It is not necessary to provide a separate backwash pipe.

Further, since the present invention treats bacteria and bacteria at high frequency, it is not necessary to use a neutralizing agent unlike other electrolysis type ship equilibrium water treatment apparatuses.

Further, the present invention has no difference in treatment performance when the ballast water is sea water or fresh water.

Fig. 3 is a view showing the construction when the ballast water is passed through the valve in the reverse direction,

[

Among the various heaters, in the present invention, a heater unit 60 using a pipe heater that can easily heat water rapidly is used.

On the other hand, the heater unit 60 using a pipe heater is widely used, and a detailed description thereof will be omitted.

If the measured values of the first temperature sensor T1 and the second temperature sensor T2 are lower than the reference value set in the set time, the heater unit 60 It is preferable to further provide a heater alarm (not shown) for recognizing that the apparatus has failed and stop the operation of the apparatus and generate a warning sound.

The electrolytic cell unit 70 is formed of a shape (not shown) in which the anode electrode and the cathode electrode are arranged facing each other, and is generally known as a mesh shape, a pipe shape, a plate shape, and the like.

(1) forward filtration + high frequency voltage application step (100)

The first valve V1 and the fourth valve V4 are opened and the second valve V2 and the third valve V3 are closed as shown in Fig. When the ballast water flows in, it enters the inner compartment 40 through the opened valve V1. Subsequently, through the filter unit 30, large particles of aquatic organisms are filtered out and left on the inner compartment 40 and the inner compartment 40 of the filter unit 30, A high frequency voltage (not shown) is applied to the electrolytic bath unit 70. At this time, the high frequency voltage is 0.5 to 10 volts at 10 to 90 MHz.

A signal converter (not shown) for generating a high frequency voltage is generally operated in a constant current mode using an element such as SCR or IGBT. When a user sets a current, a high frequency voltage is generated while automatically changing a voltage.

At this time, the ballast water to which the high frequency voltage is applied passes through the opened valve No. 4 (V4) and is discharged to the outside of the ship through the pipe pipe provided with the pressure sensor No. 2.

(2) valve closing + heating sterilization step (200)

(3) reverse filtering + high frequency voltage application step 300

If the previous step is initiated because the measured value difference of the pressure sensor has reached the set reference value, this step is automatically started immediately and if the user has started to stop discharging the ballast water, the user will start discharging the ballast water again You will begin this step in time.

When this step is started, the second and third valves V2 and V3 are opened so that the ballast water that has passed through the first pressure sensor P1 passes through the second valve V2 to the inner compartment 50 &Lt; / RTI > The aquatic organisms and large foreign particles in the ballast water are collected on the surface of the inner compartment 50 of the filter unit 30.

At this time, a substance that is collected on the surface of the inner compartment 40 side of the filter unit 30 in the forward filtration + high frequency voltage applying step 100 and sterilized in the valve closing + heating sterilization step 200, Passes through the third valve (V3) together with the ballast water that has passed through the unit (30), and is discharged to the outside of the ship through the second pressure sensor (P2).

On the other hand, when a large amount of aquatic organisms and large particles are collected on the surface of the inner compartment 50 of the filter unit 30, the measured value of the first pressure sensor P1 rises. This value and the second pressure sensor P2 ) Is equal to or greater than the set reference value, or if the user stops discharging the ballast water, this step ends and the next step starts.

(4) valve closing + heating sterilization step (400)

When this step is started, the second valve V2 and the third valve V3 opened in the previous stage 300 are closed and the heater unit 60 is operated to set the ship ballast water temperature in the apparatus housing 20 Let it be a reference value.
