The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

In addition, since the sizes and thicknesses of the respective components shown in the drawings are arbitrarily shown for convenience of explanation, the present invention is not necessarily limited to those shown in the drawings.

Also, throughout the specification, when an element is referred to as "including" an element, it is understood that the element may include other elements as well, without departing from the other elements unless specifically stated otherwise.

1 is a block diagram showing a ballast water treatment system.

Referring to FIG. 1, a ballast water treatment system 100 according to an embodiment of the present invention is a device for treating ballast water supplied to a ballast tank 30 installed in a ship or an offshore structure. Offshore structures may include floating petroleum production storage and unloading facilities (FPSO) or semi-submersible semi-rigs.

The seawater is introduced into the ship through the intake pipe 15 by the first pump 10 and then filtered through the ballast water filtration apparatus 50 to remove the foreign matter and the ballast tank 30 through the ballast water supply pipe 35. [ Lt; / RTI >

At this time, part of the seawater (hereinafter referred to as "ballast water") flowing into the ballast tank 30 through the line branched from the ballast water supply pipe 35 is supplied to the sterilizing material supply unit 20 by the second pump 22 Can be supplied.

In the sterilizing material supply unit 20, the ballast water is supplied into a generator for generating a sterilizing material, for example, sodium hypochlorite, and then electrolyzed. The generated sodium hypochlorite can be injected into the ballast water supply pipe 35.

When the sterilizing material is injected into the ballast water supply pipe 35, various kinds of harmful substances contained in the ballast water may be removed and stored in the ballast tank 30. The sterilizing material supply unit 20 may be installed on the ballast water supply pipe 35 so that sodium hypochlorite produced by electrolysis of the ballast water can be directly injected into the ballast water.

Thereafter, the germicidal material contained in the ballast water in the ballast tank 30, for example, sodium hypochlorite, is reduced to sodium chloride by natural reduction characteristics to change into seawater in a natural state, The seawater is discharged to the outside of the ship through a drain line (37). In addition, the neutralization section 40 can be installed to more completely reduce sodium hypochlorite, and the ballast water can be more completely reduced to sodium chloride due to the reducing agent supplied from the neutralization section.

2 is a side view of a ballast water filtering apparatus according to an embodiment of the present invention.

2, the ballast water filtration device 50 includes a housing 54 incorporating a filter (not shown) for filtering foreign substances in the ballast water, a connection portion 60 formed in the housing 54 and connected to the pipeline, . ≪ / RTI >

In the case of a filter for filtering foreign substances in the ballast water, a known filter may be applied. The housing 54 in which the filter is built can seal the housing 54 by connecting the first cover 52 and the second cover 53 up and down.

The connection portion 60 may be formed on the side surface of the housing 54. The connecting portion 60 includes a ballast water supply pipe 35 connected to a water intake pipe 15 and a ballast tank 30 (see FIG. 1) connected to a first pump 10 (see FIG. 1) installed in the ballast water treatment system Can be connected.

The intake pipe 15 and the ballast water supply pipe 35 may be connected at different heights in the ballast water filtration device 50. For example, the ballast water supply pipe 35 at the side of the housing 54 of the ballast water filtration device 50 can be connected at a higher position than the intake pipe 15.

The connecting portion 60, the water intake pipe 15 and the ballast water supply pipe 35 may be flanged. Therefore, the intake pipe 15 and the ballast water supply pipe 35 are provided with the flange portion at the end of the pipe, and the flange portion 62a (see FIG. 3) is also formed at the connection portion 60.

The foreign matter discharge pipe 55 of the ballast water filtration device 50 may be connected to the outside of the ship. The foreign matter discharge pipe 55 may be located at the bottom of the ballast water filtration apparatus 50. Accordingly, the foreign matter filtered from the ballast water can be discharged naturally from the ballast water filtration device 50 by gravity.

3 is a perspective view showing a connection portion connected to an opening of the ballast water filtering apparatus shown in FIG.

Referring to FIG. 3, the connecting portion 60 may protrude through the housing 54. The housing 54 may have an opening 54a through which the connecting portion 60 can pass. The opening 54a may be formed in a circular shape. That is, an opening may be formed at one side of the housing 54.

The connecting portion 60 may include a flange portion 62a connected to the pipe, a connecting member 62 connected to the flange portion 62a, and a socket portion 64 connected to the connecting member 62. [

The size of the socket portion 64 may be larger than the opening portion 54a. Therefore, the connecting portion 60 may not be separated from the housing 54. [ In particular, the socket portion 64 may be curved. Thus, the socket portion 64 can be brought into close contact with the inner side surface of the housing 54 and move along the inner side surface thereof.

A connecting member 62 is connected to the socket portion 64. The connecting member 62 passes through the housing 54 at the opening 54a of the housing 54 and the ballast water can flow in or out through the connecting member 62. [

The size of the flange portion 62a may be smaller than the opening 54a. The connecting member 62 connects between the flange portion 62a and the socket portion 64. The connecting portion 60 in which the flange portion 62a is formed can be connected to the pipe by a flange joint. However, the present invention is not limited to this, and the connecting portion 60 and the pipe may be connected by a known technique.

The angle of the flange portion 62a connected to the pipe can be adjusted up, down, left, and right. That is, it can be inclined up, down, left, and right. Further, the flange portion 62a may move up, down, left, and right within the opening portion 54a.

That is, the connecting portion 60 can change the position or angle of the flange portion 62a without moving the position of the ballast water filtration device 50 or changing the installation angle of the ballast water filtration device 50. [ Therefore, it can be more easily connected to the water intake pipe 15 (see FIG. 2) or the ballast water supply pipe 35 (see FIG. 2).

For example, when the pipe is connected to the ballast water filtration device 50, the pipe 60 and the connection portion 60 of the ballast water filtration device 50 should be in the same level position and also be horizontally aligned. However, even if there is an error of 1 mm, the pipe and the connecting portion 60 can not be interconnected because the pipe can not be bent or moved.

1) connected to the first pump 10 (see Fig. 1) or the ballast water supply pipe 35 (see Fig. 1) connected to the ballast tank 30 The intake pipe 15 and the ballast water supply pipe 35 can be more easily connected by adjusting the position or angle of the connection portion 60 of the ballast water filtration device 50 without processing for connection.

As a result, it is expected that the efficiency of the pipe construction will be greatly improved, and pipe connection can be made without welding such as 90 ° elbow or 45 ° elbow to the end of the pipe. Therefore, the labor cost and the material cost can be greatly saved.

FIG. 4 is a perspective view showing one embodiment of the connecting part shown in FIG. 3, and FIG. 5 is a sectional view showing a ballast water filtering device connected to the connecting part shown in FIG.

4 and 5, the socket portion 64a of the connection portion 60 may be formed to be curved along the inner side surface of the housing 54. As shown in FIG. That is, the socket portion 64a may be formed as a side surface of the cylinder, and the width and height of the socket portion 64a may be larger than the opening portion 54a of the housing 54. The socket portion 64a may have the same radius of curvature as the inner side surface of the housing 54. [

The socket portion 64a is connected to the connecting member 62, and a space is formed so that the ballast water can flow. As described above, the size of the socket portion 64a is larger than the opening 54a of the housing 54 and can be in close contact with the opening 54a. Thereby, the ballast water can be prevented from leaking.

Particularly, the socket portion 64a coincides with the shape of the inner surface of the housing 54, and is closely attached to the inner surface of the housing 54, so that the connection portion 60 can be easily moved and adjusted in angle. That is, the connecting portion 60 can move up and down within the opening 54a of the housing 54. [ It is also possible to move the position to the left and right. In addition, the inner guide portion 56b and the socket portion 64a are engaged with each other, so that the connecting portion 60 can be angled left and right.

An inner guide portion 56b may be formed on the inner side of the housing 54. The inner guide portion 56b may be formed so as to surround the outer side of the socket portion 64. The inner guide portion 56b may be curved along the shape of the socket portion 64a so as to surround the socket portion 64a formed on the outer side of the socket portion 64a closely contacting the inner surface of the housing 54 . The socket portion 64a is engaged with the inner guide portion 56b so that the angle of the socket portion 64a can be more easily adjusted inside the housing 54. [

An insertion member 54d may further be interposed between the inner guide portion 56b and the socket portion 64a. Accordingly, the ballast water can be prevented from leaking between the inner guide portion 56b and the socket portion 64a.

Particularly, the insertion member 54d can be deeply inserted so as to be seated between the inner guide portion 56b and the socket portion 64a even when the socket portion 64a is tilted up and down and right and left. The insertion member 54d may be made of rubber or the like.

FIG. 6 is a perspective view showing another embodiment of the connecting part shown in FIG. 3, and FIG. 7 is a sectional view showing a ballast water filtering device connected to the connecting part shown in FIG.

Referring to FIGS. 6 and 7, the socket portion 64 of the connection portion 60 may be formed as a hemisphere inside the housing 54. The socket portion 64 is connected to the connecting member 62 and a space is formed in the socket portion 64 and the connecting member 62 so that the ballast water can flow.

Particularly, the socket portion 64 is formed larger than the opening portion 54a of the housing 54 and can be in close contact with the opening portion 54a. Thereby, the ballast water can be prevented from leaking.

In particular, the connecting portion 60 having the socket portion 64 formed in a hemispherical shape is very easy to adjust the angle. Therefore, it is possible to deform at a large angle. Also, the connection portion 60 can be moved as much as a space formed between the inner guide portion 54b and the socket portion 64, which will be described later.

An inner guide portion 54b may be formed inside the housing 54. [ The inner guide portion 54b may be formed along the shape of the socket portion 64 of the connection portion 60. [ That is, along the hemispherical socket portion 64, the inner guide portion 54b can also be curved. Accordingly, the socket portion 64 is engaged with the inner guide portion 54b and can be more easily angularly adjusted inside the housing 54. [

Further, a grip portion 54c may be further formed on the inner guide portion 54b. The grip portion 54c may be connected at the lower portion of the inner guide portion 54b and extend along the inside of the socket portion 64. [

That is, the deformation of the socket portion 64 is more stable through the configuration of the grip portion 54c, and the socket portion 64 can be prevented from being separated from the housing 54. [ In addition, it is possible to prevent the ballast water inside the housing 54 from leaking between the housing 54 and the connecting portion 60.

An insertion member 54d may be further included between the socket portions 64 of the grip portion 54c. Accordingly, leakage of the ballast water between the grip portion 54c and the socket portion 64 can be prevented.

Fig. 8 is a perspective view showing a modified example of the opening of the ballast water filtering apparatus in which the connecting portion shown in Fig. 3 is protruded.

Referring to FIG. 8, an opening 54a of the ballast water filtration device 50 may be formed with an outer guide portion 54e for guiding the movement of the connection portion 60. As shown in FIG. The outer guide portion 54e may be disposed so as to form a path through which the connection portion 60 moves vertically or horizontally. Through this, the connection unit 60 can move to a predetermined path.
