It is about.

      Conventionally, ballast seawater is seawater discharged from the port where the tankers or cargo ships are unloaded in the unloading port to maintain the balance when there is no cargo, and discharged from the port loading cargo. Disturbing this ecosystem is becoming an international issue.

As described above, since the seawater inside the ballast tank is trapped in a closed space for a long time, the amount of dissolved oxygen is insufficient, and green algae which do not help the ecosystem are inhabited.

As described above, when the amount of dissolved oxygen is insufficient, the generation of green algae is greatly increased and water decays, causing a lot of problems such as accompanied by severe odors.

That is, since the seawater inside the ballast tank is a standing water, it is necessary to supply more oxygen to prevent the seawater from decaying inside the ballast tank. Because of the shortcomings, new technologies are emerging.

SUMMARY OF THE INVENTION An object of the present invention is to solve such conventional problems,

The monitor of the ship's cockpit can detect the water quality of the ballast tank at any time, and it is very efficient because it can input the quantitatively to the ballast tank by wire / wireless remote control of chemicals and microorganisms by evaluation according to the detection. The water quality of the ballast tank can be easily managed because the water quality of the pond can be managed easily, and the forced mixing part, the pressurizing part, and the pulverizing part and the vortex mixing part can also supply the maximum amount of dissolved oxygen to the water supplied to the ballast tank while passing through the natural mixing part. Its purpose is to provide a significant improvement.

According to an aspect of the present invention,

The indoor terminal is installed in the cockpit outside the ballast tank, and the outdoor terminal is installed around the ballast tank, and the data detecting the water quality of the ballast tank is transmitted from the outdoor terminal to the indoor terminal by wire or wirelessly. The terminal unit recognizes the water quality of the pond and takes action, and installs a forced mixing unit for mixing water and oxygen supplied by the operation of the pump and the booster according to the instruction of the outdoor terminal unit, and pressurization connected with the forced mixing unit. Pressurizes the water and the oxygen mixture passed through the forced mixing unit by the unit, and finely pulverizes the water and oxygen mixture pressurized in the press unit by the grinding unit connected to the press unit to increase the mixing ratio of oxygen, and then is connected to the grinding unit. The water and oxygen mixture in the state where the mixing ratio is increased by the pulverization unit by the vortex mixing unit is added to the vortex. The natural mixture is combined with the pulverization unit to allow the water and oxygen mixtures obtained by passing through the vortex mixing unit and the pulverization unit to flow naturally, and the chemical and microorganism supply unit connected with the supply line of the natural mixing unit. The purpose of the present invention can be achieved by adding chemicals and microorganisms together with the water and oxygen mixture that have been passed to the ballast tank.

In the present invention as described above, it is possible to detect the water quality of the ballast tank at any time through the monitor of the cockpit and to quantify the ballast tank by wire and wireless remote control of drugs and microorganisms by evaluation according to the detection. It is very efficient and easy to manage the water quality of the ballast tank.

Hereinafter, the operation of the present invention will be described.

First, Figure 1 is a view showing the configuration and operation of the oxygen supply device of the ballast tank for ships of the present invention, dissolved oxygen amount sensor 106 (DO detection sensor) and hydrogen ion stored in the ballast tank 181 When the dissolved oxygen amount and the hydrogen ion index fall below the set values due to the sensing action of the index detecting sensors 107 (PH detecting sensors), these sensors 106 and 107 send a signal to the outdoor terminal 101 to take action. It becomes.

The outdoor terminal 101 receiving the signals of the sensors 106 and 107 reports to the indoor terminal 171 and the outdoor side is instructed by the person in charge of operating the indoor terminal 171. The terminal unit 101 commands the operation of the pump 102 and the booster 103.

Water is supplied into the forced mixing part 111 by the operation of the pump 102 and oxygen is supplied to the air stone 112 mounted inside the forced mixing part 111 by the operation of the booster 103. Lose.

As described above, the water and oxygen forcedly mixed in the forced mixing unit 111 are pumped to the pressurizing unit 121 by the pressure of the pump 102.

The water and oxygen mixture pumped to the pressurizing unit 121 is pressurized by the pressure of the pump 102 and is cooled to the set temperature by the cooler 122 mounted inside the pressurizing unit 121. Oxygen dissolves well in water efficiently.

The cooler 122 is cooled by the coolant 122 because the refrigerant flows into the cooler 122 through the inlet 123 and then circulates through the outlet 124.

In addition, the water and oxygen mixture passed through the pressing unit 121 is introduced into the grinding unit 131.

The honeycomb structure 132 is coupled to the inside of the crushing unit 131, and the small cracks formed in the honeycomb structure are pulverized again while water and oxygen pass through, so that the finely broken oxygen is mixed with water. You can do it.

In addition, the check valve 108 is installed at the connection line between the pressurizing unit 121 and the crushing unit 131 so as not to flow back to the pressurizing unit 121 once the crushing unit 131 is introduced.

On the other hand, the water and oxygen mixture passing through the crushing unit 131 is introduced into the vortex mixing unit 141, so that the vortex is formed by the spiral body 142 mounted inside the vortex mixing unit 141, so that water and oxygen They get tangled and mix again.

As described above, the water and oxygen mixture passing through the plurality of crushing units 131 and the vortex mixing unit 141 flows into the natural mixing unit 151 and includes a plurality of diaphragms formed in a zigzag inside the natural mixing unit 151 ( The natural flow is achieved by the guidance of 152).

In addition, oxygen remaining without dissolving in water in the natural mixing unit 151 is positioned above the natural mixing unit 151, and the oxygen is connected through a connection line connected to the upper side of the natural mixing unit 151. The connection line connecting the booster 103 and the forced mixing unit 111 is supplied through the check valve 109 to be reused.

In addition, when the water and oxygen mixture passes through the natural mixing unit 151, the supply control valve 104 is opened by the instruction of the outdoor terminal 101, and the high-purity water and oxygen mixture is transferred to the ballast tank 181. It can be supplied.

When the supply of drugs and microorganisms is required, the on / off valve 105 may be opened by the instruction of the outdoor terminal 101 to supply the necessary amount of drugs or microorganisms.

As described above, according to the present invention, when the supply of water and oxygen mixture and chemicals or microorganisms is completed, the supply control valve 104 and the shut-off valve 105 are closed by the instruction of the outdoor terminal 101 and the pump 102. Also stops the operation of the booster 103 and waits for the next instruction.
