Description

Technical Field [0001] The present invention relates to a ballast water treatment system using a hydro crusher for ballast water treatment using friction and collision of solid particles flowing in the vortex,

The present invention relates to a marine ballast water treatment system using a hydro crusher for ballast water treatment using friction and collision of particles flowing in a swirling flow.

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, ballast water plays a role as a weight to adjust the ship's draft and trim.

On the other hand, a ship which has ballast tanks with ballast water and which arrives at a port in another region or another country discharges ballast water to the sea of the destination and reloads the cargo after reducing the weight of the ship.

The ballast water is essential for maintaining the 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 is also possible to mix the seawater belonging to different areas of the ballast water equilibrium I can not deny that I will play a role. In other words, since the creatures in a specific sea area contained in the ballast water are transported to and discharged from the seas of completely different areas by the movement of the vessel containing the ballast water, the ecosystem is disturbed by mixing the living organisms of different ecosystems. Coastal fisheries and other industrial activities or resources.

Based on the above situation, the International Maritime Organization (IMO) concluded an international agreement in February 2004, and from 2009 onwards, the ship was required to install the necessary equipments for disinfection of ship ballast water. In addition, the United States Coast Guard (USCG) applies to vessels operating in all areas of the US exclusive boundary waters, apart from IMO.

Therefore, all ships operating in foreign countries can only be operated with a ship ballast water treatment system approved by IMO and USCG. Therefore, various technologies for treating ship ballast water have been developed recently.

According to one or more embodiments of the present invention, a ship ballast water treatment system using a hydro crusher for ship ballast water treatment using friction and impact of particles flowing in the vortex can be provided.

According to one or more embodiments of the present invention, there is provided a ship ballast water treatment system using a hydro crusher for ship ballast water treatment, which is installed together with existing ship ballast water sterilization apparatuses and physically sterilizes ship ballast water .

Terms

As used herein, the expression "treating", "killing" or "sterilizing" a ship ballast water means killing or deactivating the organisms contained in the ballast water (eg, zooplankton, phytoplankton, bacteria) .

1 is a view for explaining a ship ballast water treatment system using a hydro crusher for ship ballast water treatment according to an embodiment of the present invention.

1, the ship ballast water treatment system according to the present embodiment includes a seed chest 10, a ballast water storage tank 40 for storing sterilized ship ballast water, a main ballast water main pipeline L1, L2 , L3, a hydro-crusher 20 for treating ship ballast water (hereinafter referred to as a "hydro crusher"), and a pump P1.

The sea chest (10) is the place where sea water is used as the ballast water from the sea. The ballast water flowing into the seed chest 10 is supplied to the hydro crusher 20 through the ship ballast water main pipe L1 connected to the seed chest 10. The ballast water flowing in the ship ballast water main pipeline L1 may be pumped by the pump P1 provided on the main pipeline L1 and supplied to the hydro crusher 20.

The hydro crusher 20 according to the present embodiment has particles (hereinafter referred to as " fluid particles ") flowing by the shape of the hydro crusher, the velocity of the ballast water and the vortex flow generated by the hydraulic pressure, Flowing particles collide and friction with each other and crush into the shape by rotating by the vortex generated in the hydro crusher. On the other hand, the organisms contained in the ship ballast water are killed or deactivated by colliding with friction particles which are in contact with each other.

The hydro crusher 20 according to the embodiment of the present invention is configured such that the flowing particles contained in the hydro crusher 20 itself remain in the interior of the self crusher 20 without flowing out to the outside by the ballast water.

According to an embodiment of the present invention, the hydro crusher 20 may be installed on the main piping existing between the seed chest 10 and the ballast water storage tank 40. Here, the main piping provides a path through which ship ballast water can move from the seed chest 10 to the ballast water storage tank 40.

In the present description, for the purpose of the present description, the main piping existing between the seed chest 10 and the hydro crusher 20 is present between the main piping L1, the hydro crusher 20 and the sterilizing section 30 The main piping L2 and the main piping existing between the sterilizing unit 30 and the ballast water storage tank 40 will be referred to as a main piping L3.

The ship ballast water is pumped from the seed chest 10 by the pump P1 provided on the main pipeline L1 and flows into the hydro crusher 20. [

The ballast water introduced into the hydro crusher 20 is subjected to physical movement such as collision or friction with the particles flowing by the shape of the hydro crusher 20, the velocity of the ballast water and the vortex flow generated by the hydraulic pressure And then flows out of the hydro crusher 20 after destroying the organisms contained in the ballast water.

A more detailed description of the hydro crusher 20 will be given later with reference to Figs. 2 to 6.

The ship ballast water treatment system according to the present embodiment may further include a sterilizing unit 30. The sterilizing unit 30 may be installed between the hydro crusher 20 and the ballast water storage tank 40 and may supply the ballast water discharged from the hydro crusher 20 to the main pipeline L2 And sterilized.

In this embodiment, the sterilizing unit 30 can sterilize the ballast water using ozone, UV, or electrolysis. The sterilizing unit 30 can be applied to the present embodiment as long as it is a device capable of sterilizing ship ballast water regardless of the technique.

For example, Korean Patent Application No. 2013-0107176 (filed on Mar. 31, 2013, entitled " Method and apparatus for automatic control of ozone gas concentration and flow rate through TRO concentration measurement in a ballast water sterilization system using ozone) A technique for sterilizing ship ballast water by using the above-mentioned method. The techniques described in this Korean patent application number are incorporated herein by reference to the extent not inconsistent with the present invention.

In another example, Korean Patent Application No. 2010-0035788 (filed on April 19, 2010, entitled "Ballast water sterilization device for ships") discloses a technique for sterilizing ballast water using ultraviolet rays. The techniques described in this Korean patent application number are incorporated herein by reference to the extent not inconsistent with the present invention.

As another example, Korean Patent Application No. 2011-0067818 (filed on July 8, 2011, entitled "Method of Treating Ballast Water from Ships Using an Electrolysis Unit") discloses a technique for sterilizing ballast water using electrolysis . The techniques described in this Korean patent application number are incorporated herein by reference to the extent not inconsistent with the present invention.

As another example, the sterilizing section 30 may have the same configuration as the hydro crusher 20 according to an embodiment of the present invention.

As described above, the sterilizing section 30 performs the sterilizing operation again after being primarily sterilized by the hydro crusher 20, thereby improving the sterilizing performance against the ship ballast water.

Further, the sterilizing unit 30 sterilizes the ballast water together with the hydro crusher 20 so that the oxidizing agent 30 contributes to sterilization in the case of chemical sterilization rather than sterilizing the ballast water by itself 30 without the hydro crusher 20. [ , Which can eventually lead to downsizing of the equipments of ship ballast water and use less resources.

For example, when the sterilizing unit 30 is a device for sterilizing ship ballast water using ozone, the ballast water can be sterilized by using a relatively small amount of ozone. As another example, when the sterilizing unit 30 is a device for sterilizing ship ballast water by using UV or electrolysis, the ballast water can be sterilized by using a relatively small amount of electric power. Therefore, it is possible to miniaturize the construction equipment.

The ballast water storage tank 40 according to the present embodiment stores the ballast water sterilized by the hydro crusher 20 and the sterilizing unit 30. The ballast water stored in the ballast water storage tank 40 may be discharged to the outside through a pipe L4 connected to the ballast water storage tank 40 when discharging is required. When discharged to the outside, the sterilizing unit 30 is discharged as it is according to the manner of the sterilizing unit 30, or it is discharged after being neutralized by injecting the neutralizing agent. For example, when the sterilizing unit 30 sterilizes ship ballast water using ozone, the ballast water stored in the ship ballast water storage tank 40 is neutralized and discharged by the neutralizing agent when it is discharged to the outside. Korean Patent Application No. 2009-0023795 (filed on Mar. 3, 2009, entitled "Ship Equilibrium Water Neutralizer and Neutralization Method") describes a technique of neutralizing ozone gas and discharging it to the outside. The techniques described in this Korean patent application number are incorporated herein by reference to the extent not inconsistent with the present invention.

On the other hand, the ballast water is sterilized in the course of passing through the flowing particles 50 which cause friction with each other.

On the other hand, it is preferable that the floating particles 50 have a weight and a size such that they can be moved (including elevation) by the ballast water. It is necessary to have a weight and a size that can be raised by the ship ballast water so that the flowing particles 50 hit each other and thereby the ballast water can be sterilized.

The hydro crusher 20 according to the present embodiment may include a filter 60. The filter 60 may pass through the ballast water and perform any one or more of the following operations.

 At least a part of the column 27 is coupled to the inner surface forming the inner space S1. For example, one end of the column 27 may be coupled to either the upper surface S3 or the lower surface S5. Alternatively, one end of the column 27 may be connected to either the filter 60 or the lower surface S5.

The column 27 is positioned at the center of the internal space S1 so that a central axis (hereinafter referred to as a "center axis") can be formed in the internal space S1 of the body portion 25 as shown in FIG. 2 And one end of the column 27 is coupled to the lower surface S5 of the inner surface forming the inner space S1 and the other end of the column 27 is coupled to the filter 60 . Such coupling is illustrative and it is also possible to combine them in other ways.

In this embodiment, the body portion 25 includes an inlet H1 capable of receiving the ballast water into the internal space S1 and a discharge portion H3 capable of discharging the ballast water introduced through the inlet H1 H2).

The inlet H1 is positioned such that the ballast water enters the filled portion of the flowing particles 50. For example, as shown in Fig. 2 (a), the inlet H1 may be positioned on the side surface S7 of the inner surface adjacent to the lower surface S5.

The discharge unit H2 may be connected to at least one of a side surface S7 and an upper surface S3 of the inner surface of the body portion 25. [ For example, on the side surface S7 between the filter 60 and the upper surface S3 as shown in Fig. 2 (a).

As described above, the configuration in which the hydrocracker 20 includes the inflow pipe 21 and the discharge pipe 23 is merely an example, and it is also possible to arrange not to include the inflow pipe 21 and the discharge pipe 23. For example, the main pipeline L1 for supplying the ship ballast water from the seed chest 10 may be directly connected to the inlet H1 to provide the ship ballast water. The main pipe L2 connecting the hydro crusher 20 and the sterilizing unit 30 shown in FIG. 1 is directly connected to the discharge unit H2 so that the ballast water sterilized in the hydro crusher 20 is discharged to the main pipe (L2).
