Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ballast water treatment system installed with a collision device as a pretreatment device,

The present invention relates to a marine ballast water treatment system having a collision-based sterilizing unit.

 A ship is widely used as a means of transporting large quantities of goods at once or for military purposes. If there are not enough people, equipment, and goods (collectively referred to as cargo), the ship will not sink sufficiently into the water, so it can be easily shaken by small waves, and even propellers and rudders are not sufficiently immersed in water. It is not operated efficiently.

Accordingly, a ship unloading cargo is operated in a state in which ballast water (ballast water) (also referred to as "ballast water") is stored in a ballast tank in order to maintain balance and stability. As a result, the ballast acts as a weight to adjust the ship's draft and trim.

On the other hand, a ship carrying ballast tanks with ballast water and arriving at a port in another region or another country discharges the ballast water to the sea of the destination to reduce the weight of the ship and load the cargo again.

The ballast water is essential for maintaining balance and stability of the ship. On the other hand, since the ballast water is stored in the ballast tanks for a long time, it plays a role of mixing seawater belonging to different regions of equilibrium In order to prevent disturbance of the marine ecosystem, the ballast water is sterilized and stored in the ballast tanks.

Thus, although various alternatives for solving these drawbacks have been suggested, up to now, the treatment efficiency of the equilibrium water is insufficient compared to the investment cost or equipment size.

According to an embodiment of the present invention, a pretreatment apparatus for a ship ballast water treatment system capable of effectively removing organisms (animal and phyto plankton) present in ballast water can be provided.

According to an embodiment of the present invention, a sterilizing apparatus used in a ship ballast water treatment system to effectively remove organisms present in ballast water can be provided

According to an embodiment of the present invention, there is provided a plasma processing apparatus including: a collision portion installed inside a pipe through which a ballast water flows; And

And a mesh net installed in the piping.

According to another embodiment of the present invention, in a collision portion used in a marine ballast water treatment system,

Body part; And a plurality of serration assemblies, wherein the plurality of serration assemblies are multilayered on the body portion.

According to one embodiment of the present invention, it is possible to directly generate collision and turbulence and effectively remove the organisms that are present in the ballast water and enter the ship. This can reduce the load on the downstream sterilizer.

1 is a view for explaining a marine ballast water treatment system having a collision-based sterilizing unit according to an embodiment of the present invention.

1, the present ship ballast water treatment system includes a compressor 101, an air dryer 103, an oxygen generator 107, an ozone generator 111, a central control unit 113, a chiller 115, A gas disruption unit 119, a sterilizing unit 200, and a neutralizing agent storage unit 402 for storing a neutralizing agent. Here, the neutralizing agent may be, for example, any one selected from the group consisting of sulfite, sulfur dioxide, sodium hydrogensulfite and sodium sulfite, but the neutralizing agent usable in the present invention is not limited thereto.

The compressor 101 receives air from the outside, compresses it, and supplies the compressed air to the air dryer 103. The air dryer 103 dries air supplied from the compressor 101 and supplies it to the oxygen generator 107.

The oxygen generator 107 receives the dried air from the air dryer 103 to generate oxygen of high purity. Here, the oxygen generator 107 may be, for example, a conventionally known oxygen generator or an oxygen generator developed after the present patent application.

The ozone generator 111 receives the high-purity oxygen generated by the oxygen generator 107 to generate ozone gas. In this embodiment, a large amount of heat is generated in the ozone generator 111, so that the ozone generator 111 can be cooled by the chiller 115 or a cooler (not shown).

The central control unit 113 can control the operation of each device.

When the ozone gas destruction portion 119 needs to destroy the ozone gas present in the ozone gas inflow line, the ozone gas destruction portion 119 can discharge the ozone gas to the atmosphere after destroying the ozone gas.

The sterilizing unit 200 destroys (destroys) the organisms present in the equilibrium water. Although one sterilizing unit 200 is shown as an example, it is also possible to install two or more sterilizing units 200 in the ballast inflow main line L31.

Although ozone gas is directly injected into the sterilizing unit 200 in this embodiment, ozone gas is not directly injected into the sterilizing unit 200 but may be injected into the sterilizing unit 200 have. 8 shows that the ozone gas is injected upstream of the sterilizing unit 200. In this case,

The ship ballast water treatment system may further include a water vent 302 for discharging the counterflow water to the outside in case the ballast water flows backward through the ozone gas inflow line. This is because if the counterflow water flows into the ozone generator, it can damage the ozone generator.

The ship ballast water treatment system includes an operation for destroying and storing organisms in the seawater as ballast water (hereinafter referred to as a "sterilization mode") and a mode for neutralizing the sterilized seawater to discharge it to the outside (a "neutralization mode") Can be performed. Hereinafter, the sterilization mode and the neutralization mode will be sequentially described.

Sterilization mode

The valve V41 and the valve V33 are opened, and the valve V43 and the valve V45 are closed. The opening or closing of these valves may be done manually or automatically by a control device such as the central control 113.

The ballast pump P33 pumps the ballast water into the ballast water inflow main line L31.

The sterilizer 200 kills the organisms present in the ballast water which has been moved from the inside of the ballast water inflow main line to the ballast tank 303. A detailed description of the sterilizer 200 will be given with reference to FIGS. 2 to 8. FIG.

Neutralization mode

In the neutralization mode, the present ship ballast water treatment system neutralizes the ballast water filled in the ballast tank 303 and discharges it to the outside.

The valve V33 and the valve V41 are closed and the valve V34, the valve V43 and the valve V33 are opened. The opening or closing of these valves may be done manually or automatically by a control device such as the central control 113.

The ballast pump P33 pumps the ballast water filled in the ballast tank 303 to flow into the ballast water inflow main line L31. The ballast water flowing along the inside of the ballast water inflow main line L31 is neutralized by the neutralizing agent supplied from the neutralizer storage 402 and then discharged through the valve V34.

2 and 3 are views for explaining a sterilizing unit according to an embodiment of the present invention.

2 and 3, a sterilizer according to an embodiment of the present invention includes a collision portion 280, an actuator 401, pressure sensing portions 403 and 405, an ozone gas injection portion 407, (408).

The collision portion 280 is a portion which collides with the ballast water flowing in the ballast water inflow main line L31 so that when the organism existing in the ballast water inflow main line L31 collides with the impact portion 280, Consists of.

The mesh net 408 is installed inside the ballast water inflow main line L31. For example, the mesh network 408 may be installed upstream of the impact portion 280, but it is also possible that the mesh network 408 is installed downstream of the impact portion 280 as an example. Although only one mesh network 408 is shown, it is also possible to install two or more mesh networks 408.

The actuator 401 can rotate the mesh network 408. [

The sterilizer 200 according to an embodiment of the present invention may further include means for detecting that at least a part of the mesh network 408 is blocked. The mesh network 408 may be occluded by a mud or the like and is for detecting this.

The ozone gas injection unit 407 is formed in the ballast water inflow main line L31 and the ozone gas generated by the ozone generator 111 flows through the ozone gas injection unit 407 into the ballast water inflow main line L31, Respectively.

According to the present embodiment, the ozone gas injection unit 407 is provided upstream of the position of the mesh net 408 to inject ozone gas. The position of the ozone gas injection unit 407 is an example, and it is also possible that the ozone gas injection unit 407 is installed downstream of the mesh network 408 to inject ozone gas.

According to an embodiment of the present invention, the means for detecting that at least a part of the mesh network 408 is blocked may be the pressure sensing units 403 and 405 for sensing the pressure.

For example, the pressure sensing units 403 and 405 can measure the pressure of the ballast water before passing through the mesh net 408 and the pressure of the ballast water after passing through the mesh net 408 with respect to the mesh net 408, Lt; / RTI > For example, the pressure sensing units 403 and 405 may include a pressure sensing unit 405 sensing the pressure of the ballast water before the ballast water passes through the mesh net 408, And a pressure sensing unit 403 sensing the pressure of the water.

The detection results of the pressure sensing units 403 and 405 may be provided to the central control unit 113. [

The central control unit 113 can control the operation of the actuator 401. The central control unit 113 controls the operation of the actuator 401 based on the pressure difference between the pressure of the ballast water before passing through the mesh net 408 and the pressure of the ballast water after passing through the mesh net 408.

When the difference between the pressure of the ballast water before passing through the mesh net 408 and the pressure of the ballast water after passing through the mesh net 408 reaches a predetermined value or more, the central control unit 113 controls the actuator 401, And rotates the mesh 408 by a predetermined angle (e.g., 180 degrees).

In this embodiment, a rotation axis AX is coupled to the center of the mesh net 408, and the rotation axis AX is interlocked with a drive shaft (not shown) of the actuator 401. When the drive shaft (not shown) of the actuator 401 is rotated, the rotation axis AX is rotated in conjunction with the rotation.

In the present specification, for the purpose of the present invention, a state in which the mesh network 403 is aligned in the direction of blocking the ballast water is defined as a 'blocking state'.

8 is a view for explaining the operation of the actuator.

Referring to FIG. 8, it is shown that the mesh network 408 is rotated by the actuator 401.

For example, the mesh network 408 may be rotated 180 times in the blocked state. 8 shows that when the difference between the pressure of the ballast water before passing through the mesh net 408 and the pressure of the ballast water after passing through the mesh net 408 becomes equal to or larger than a predetermined value, the actuator 401 rotates the rotation axis AX Thereby rotating the mesh net 403 by 180 degrees.

The central control unit 113 controls the actuator 401 whenever the pressure difference between the pressure of the ballast water before passing through the mesh net 408 and the ballast water after passing through the mesh net 408 becomes equal to or greater than a predetermined value The mesh network 403 is switched 180 degrees.

According to an embodiment of the present invention, when the mesh network 408 is in the shutdown state, organisms existing in the equilibrium water can be secondarily destroyed by the mesh network 408. That is, the creatures existing in the ballast water are primarily destroyed by the collision portion 280, and are destroyed by the mesh net 408 secondarily.

If the mesh net 408 is maintained for a long time in a blocked state, the mesh net 408 may be blocked by a mud or the like. In this case, the mesh network 408 is switched 180 degrees by the actuator 401 in order to eliminate the mud or the like.

According to an embodiment of the present invention, the mesh network 408 may be fixedly positioned between the flanges F2 and F3.

At least one serration assembly 302 is attached to the surface of the body portion 287. The serration assembly 302 is attached to the body portion 287 such that the teeth 298 collide frontally with the ballast water. For example, a plurality of serration assemblies 302 are attached to the body portion 287 to surround the body portion 287 in a circular manner. In addition, the plurality of sawtooth assemblies 302 are arranged in a multi-layered fashion surrounding the body portion 287.
