Description

Ship Ballast Water Treatment System {BALLAST WATER TREATMENT DEVICE FOR SHIP}

The present invention relates to a ship ballast water treatment apparatus, and more particularly, to improve the installation and construction efficiency of a water treatment facility for the treatment of ballast water.

Unlike small ships that are generally thought of, when a large ship operates in an empty ship, the center of gravity is on the upper side, so there is a risk of overturning due to severe rocking from side to side, and the propeller is not locked so that the propulsion efficiency is greatly reduced.

To prevent this problem, separate tanks, called ballast tanks, are installed at the bottom and left and right sides of the hull and contain water, which is called ballast water or ballast water. Like a toy tower, the center of gravity is directed down so that the ship can secure resilience and propulsion at the proper surface.

Before the mid-twentieth century, when the ballast tanks could not be built, the ships were balanced by sandbags or gravel. The original meaning of the ballast came from 'black pebbles'.

If it is necessary to sail on an empty ship, the ballast water is designed to fill approximately one-third of the cargo that the ship can carry, and a 300,000 tonne (GT) crude oil carrier would have a capacity of 100,000 tons of ballast tanks. All. When departing on an empty ship to load cargo from the port of departure, the seawater is placed in a ballast tank, and when the cargo arrives at the destination, the seawater of the ballast tank is dumped in the harbor. It reaches 10 billion tons annually.

On the other hand, such ballast water contains various marine organisms present in the seawater of the region where the ballast water is introduced.If the ballast water is released from other regions after the ship moves, marine organisms of other regions threaten the ecosystem. There is a serious problem.

In 1996, the US enacted the National Invasive Species Act in 1996, mandatory foreign species as invaders, and mandated management and control of ballast water. We carry out.

In addition, the International Maritime Organization signed an international agreement in February 2004, and since 2009, the ballast sterilization unit should be mounted on ships in order to prohibit entry of the vessel in case of violation. The entry into force of this Convention shall be twelve months after the date on which at least 30 countries become Parties, of which the sum of the number of merchant ships combined is at least 35% of the world merchant ships.

For example, after 2012 keel laying (keel laying) the installation of the ballast processing unit to all the ships have a 5000m ³ or more ballast tanks is mandatory that, because the flights are vessels are also be additionally installed ballast processing unit designed and arranged side of the vessel Can be significantly affected

In particular, ships such as the VLCC (Very Large Crude Oil Carrier) have been accumulated with a long experience and applied to the optimized hull layout. When the ballast treatment unit is newly installed, There was a problem in that the layout and design of the entire relevant part including the tank tank had to be changed.

In addition, the cost and time required by such arrangement and design changes were also a problem.

The present invention has been proposed to improve the above problems in the prior art, and provides an installation cost and time by providing a structure that can easily secure the processing space of the ballast while maintaining the hull arrangement and design of the existing vessel intact The goal is to minimize it.

According to the present invention for achieving the above object, a pump room in which a plurality of pumps are installed in the center of the deck bottom of the ship is configured, the fuel oil storage tanks are provided in a symmetrical form on both sides of the pump room, the fuel oil storage In the outer side of the tank and the lower part of the pump room is configured a ballast storage tank for storing the ballast water, the upper deck deck ballast water treatment system is configured with a ballast treatment for treating the ballast water, the pump room in the ballast ballast storage tank A ballast pump for forcibly circulating water through the conveying pipe to the ballast processing unit is installed; The upper one side of the pump room is characterized in that the guide duct is provided for guiding the transport pipe is connected to the ballast processing unit.

The present invention, it is possible to install the ballast water treatment apparatus in the existing design and built vessels without further modifications to exhibit the effect of reducing the labor and the material of the pipeline.

In particular, the pipe connected to the ballast pump has an arrangement structure that does not pass through the fuel oil storage tank can achieve an optimum arrangement form.

1 is a schematic cross-sectional view of a vessel to which the ballast water treatment apparatus of the present invention is applied.
FIG. 2 is a detailed view of portion A of FIG. 1; FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, looking at the vessel structure to which the ballast water treatment apparatus according to an embodiment of the present invention is applied, the pump room 20 is provided with a plurality of pumps are installed in the center of the lower deck 10 of the vessel, the pump room ( 20) On both sides, the fuel oil storage tank 30 is provided in a symmetrical form, and the ballast storage tank 40 in which the ballast water is stored outside the fuel oil storage tank 30 and the lower part of the pump room 20 has a hull. It is configured in a wrapping form, it can be seen that the ballast processing unit 50 is a facility for purifying the ballast water on the deck 10, the top.

In particular, in the present invention, a ballast pump 45 for forcibly circulating the ballast water of the ballast storage tank 40 to the ballast processing unit 50 through the feed pipe 46 is installed in the pump room 20, the pump room The guide duct 21 for guiding the conveying pipe 46 which is connected to the ballast processing unit 50 is configured on one side of the upper portion 20.

That is, the guide duct 21 is provided so as to protrude toward the fuel oil storage tank 30 to achieve an optimum arrangement while the transfer pipe 46 does not pass through the fuel oil storage tank 30.

In the figure, reference numeral 41 denotes a partition bulkhead for partitioning the left and right sides of the ballast storage tank 40.

The effect of the present invention to form the arrangement structure of the ballast water treatment device as described above will be described.

In order to install the ballast water treatment apparatus of the present invention, the ballast treatment unit 50 must be installed on the deck 10. The upper section of the fuel oil storage tank 30 is provided with an upper portion of the pump room 20 because the design is protruded. Installation should be done at

However, when the ballast treatment unit 50 is installed in the upper region of the fuel oil storage tank 30, the transfer pipe 46 for transferring the ballast water should be arranged in such a way as to surround the fuel oil storage tank 30. Difficulties in batching and excessive consumption of the material in the pipeline are created.

Therefore, in the present invention, it is possible to solve the above difficulty by configuring the guide duct 21 for guiding the transfer pipe 46 is connected to the ballast processing unit 50 on the upper side of the pump room (20).

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the ballast water treatment device arrangement of the present invention may be variously modified and implemented by those skilled in the art.

However, such modified embodiments should not be understood individually from the technical matters or the scope of the present invention, and such modified embodiments should be included in the appended claims of the present invention.
