BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions in the embodiments of the present invention, which may vary depending on the intention of the user, the intention or the custom of the operator. Therefore, the definition should be based on the contents throughout this specification.

There are many cases in which a generator exhaust pipe is pulled out to the side in order to install a weapon on a ship, especially a main deck in the case of a ship. In this case, as the height of the outlet of the exhaust pipe installed on the side of the ship becomes lower than the sea level due to the rolling of the vessel, the sea water may flow backward through the outlet of the exhaust pipe and flow into the generator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, which illustrate a system and method for preventing seawater backflow through an exhaust pipe of a ship according to the present invention.

FIG. 3 is a conceptual view for schematically illustrating a seawater backflow prevention system through an exhaust pipe of a ship according to an embodiment of the present invention. FIG. 4 is a schematic view illustrating a seawater backflow prevention system through an exhaust pipe of a ship according to an embodiment of the present invention. FIG. 2 is a view for explaining an operation effect of the prevention system.

3 and 4, a seawater backflow prevention system 100 (hereinafter simply referred to as a "seawater backflow prevention system") through an exhaust pipe of a ship according to an embodiment of the present invention includes a buffer chamber An air vent 120, a drain line 130, and a drain pump 140. In this embodiment,

The buffer chamber 110 may be formed in communication with the exhaust pipe 20 of the generator 10 having the outlet formed through the hull of the ship (particularly, a trap).

The buffer chamber 110 may be provided in a form capable of accommodating the countercurrent seawater through the exhaust pipe 20, and is not limited to the illustrated shape.

For example, the buffer chamber 110 may include an exhaust pipe (not shown) disposed below the sea surface when the vessel (particularly, the vessel) is rolled at a predetermined angle (See FIG. 4) that is capable of receiving the seawater W (see FIG. 4) that has been countercurrently flowed through the outlet of the water outlet 20, can be variously shaped.

Drain line 130 refers to a piping facility connected to discharge the countercurrent seawater W (see FIG. 4) to the outside of the vessel (particularly, a vessel) when the vessel is accommodated in the buffer chamber 110.

Accordingly, the drain line 130 is not limited to the illustrated shape and arrangement, and can be variously implemented.

As a preferred example, the drain line 130 may be connected between the buffer chamber 110 and the bilge line of the vessel. Specifically, the inlet side of the drain line 130 may be connected to the lower portion of the buffer chamber 110, and the other side of the drain line 130 may be connected to the bilge line of the vessel. According to this structure, the countercurrent seawater W (see FIG. 4) accommodated in the buffer chamber 110 can be prevented from flowing back to the outside of the ship (particularly, the ship) to the generator 10.

The drain pump 140 may be installed in the drain line 130. The drain pump 140 is not limited to the type and shape of a conventional pump.

As the drain pump 140 is driven, the seawater W (see FIG. 4) accommodated in the buffer chamber 110 is pushed toward the drain line 130 and then discharged to the outside through the bilge line of the ship .

Meanwhile, the air vent 120 functions to circulate the air inside the buffer chamber 110.

For example, part of the reverse flow of seawater may be accommodated in the lower portion of the buffer chamber 110, so that the air vent 120 is formed to pass through the upper end of the buffer chamber 110. However, it is not necessarily limited thereto.

Hereinafter, a method for preventing reverse flow of seawater through an exhaust pipe of a ship according to an embodiment of the present invention including such a structure will be briefly described.

5 is a flowchart briefly showing a method of preventing seawater backflow through an exhaust pipe of a ship according to an embodiment of the present invention.

4, the outlet of the exhaust pipe 20 (see FIG. 4) is positioned below the sea level, as shown in FIG. 4, The seawater can be backflowed through the exhaust pipe 20 (see Fig. 4).

In this situation, the seawater W (see FIG. 4), which is reversed through the outlet of the exhaust pipe 20 (see FIG. 4), may first be received into the buffer tank 110 (see FIG. 4) (S100).

4) to transfer the seawater W (see FIG. 4) accommodated in the buffer tank 110 (see FIG. 4) toward the drain line 130 (see FIG. 4) (S200). At this stage, as the drain pump 140 (see FIG. 4) is driven, seawater can be fed from the inside of the buffer tank 110 (see FIG. 4) toward the drain line 130 (see FIG. 4).

As a next step, seawater contained in the buffer tank 110 (see FIG. 4) by driving the drain pump 140 (see FIG. 4) may be transferred through the drain line 130 (see FIG. 4) (S300).

4) is connected to the lower portion of the buffer tank 110 (see FIG. 4), and the outlet side of the drain line 130 (see FIG. 4) , And the seawater pumped through the drain line 130 (see FIG. 4) may be discharged to the outside through the bilge line of the ship (particularly, the ship).
