Description

The ship

The present invention relates to a ship, and more particularly, by additionally arranging an external air blocking wall that can significantly reduce the flow rate of the external air through the preliminary blockage of the outdoor air flowing toward the stack or the residence. By blocking and suppressing <the creation of a low pressure space in the region between the stack and the inlet port> due to the rapid inflow of outdoor air, thereby preventing the exhaust gas discharged from the stack from being unnecessarily entrained in the inlet port side, Various damages due to inflow of large amount of exhaust gas from the source using living quarters (e.g., damage to health due to exhaust gas, damage to own living space and operating space by exhaust gas, polluted living space and operation) It may cause a large amount of manpower and time to be recovered to recover space, and malfunction of the navigation system. Refers to ships that can guide effectively avoiding damage, such as damage that requires a large amount of manpower and time to recover from malfunction of the navigation system.

Recently, as various economic activities including international trade have been greatly activated, the demand for use of ships has also increased rapidly. Therefore, how to improve the quality of use of ships has emerged as an important social issue.

Normally, under such a conventional system, as shown in FIG. 1, the stack 12, the residence port (on the ship 10) (for example, a cargo transport ship, a passenger transport ship, a drilling ship, etc.) on the hull 11 side. 13) By quickly proceeding to the destination with various structures such as the ship, it is possible to perform various cargo transportation roles, passenger transportation roles, drilling roles, etc. assigned to them.

At this time, the previous stack 12 is, for example, in the state arranged in the rear of the hull 11, the various hulls (Y) generated during the operation of the ship 10 (for example, odor, soot, tar, etc.) hull ( By discharging to the outside of the 11), it serves to block the contamination of the hull 11 by the exhaust gas (Y) in advance, and in various sizes on the inlet 13 side adjacent to the stack 12 By providing various types of rooms, living spaces for sailors sailing for a long period of time (e.g. sailor accommodation rooms, sailor meal rooms, rest rooms, etc.) and operating spaces for operation of the ship 10 (hull) (e.g., Ship steering room, ship engine room, etc.) to provide a wide range.

Under such a conventional system, when the hull 11 of the ship 10 is operated for a predetermined speed or more in the direction of the arrow A1, the outside air around the hull 11 is along the arrow A2 in the opposite direction, the hull 11 It takes a pattern that flows rapidly in the direction of the chimney 12 and the residence port 13 disposed at the rear end of (in this case, the flow speed of the outside air is proportional to the operating speed of the hull 11).

Of course, in this situation, if no action is taken, some of the fresh air that has flowed rapidly in the aft direction of the hull 11 will show a mechanical mechanism that follows the arrow A3 and rides over the top of the dwelling port 13. The outside air introduced in this way flows between the inlet 12 and the stack 13 (that is, the rear end of the inlet 13) to form an unnecessary low pressure space in the region B.

Naturally, the low pressure space thus formed is able to exert a very strong vacuum effect throughout its periphery due to the inherent pressure characteristics maintained low, and as a result, discharged from the stack 12 side as shown in FIG. 2. A part Y1 of the various exhaust gases Y follows the arrow A5, the sieve which has not normally discharged to the outside of the hull, and the arrow A4, the low pressure of the region B between the inlet 13 and the stack 12 It causes a serious problem of being strongly involved in space.

Of course, under the condition of causing this problem, along the arrow A4, the exhaust gas Y1 entrained into the low pressure space of the region B between the inlet 13 and the stack 12 flows intact into the inlet 13. In the end, the source using the inlet 13 causes various damages caused by the inflow of the exhaust gas Y1, for example, damages deteriorated by the exhaust gas Y1, and exhaust gas Y1. ) Causes damage to self-contained living spaces and operating spaces, damages that require a large amount of manpower and time to recover contaminated living spaces and operating spaces, and malfunctions of navigational devices (eg engines, steering, etc.). It is inevitable that the damage caused, the large amount of manpower and time required to recover the malfunction of the navigation system, and so on.

Accordingly, an object of the present invention is to provide a rapid inflow of outside air by further arranging an outside air blocking wall that can significantly reduce the flow rate of the outside air through the preliminary blockage of the outside air flowing toward the stack or inlet, in front of the stack or inlet. By preventing and suppressing the &quot; low pressure space generation in the region between the stack and the inlet zone &quot; In order to recover various damages (e.g., damage to health deteriorated by exhaust gas, damage to own living space and operating space by exhaust gas, pollution contaminated living space and operating space) Damage that must consume a large amount of manpower and time, damage that causes malfunction of the navigation system, It is to guide to avoid damage, etc.) that should consume massive manpower and time effective to restore the operation.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In the present invention to achieve the above object and the hull; A stack for discharging the exhaust gas generated during operation of the hull to the outside in a state mounted on the hull; A dwelling area which is arranged adjacent to the stack and provides a living space for crew or a navigation space for the operation of the hull; While spaced apart in front of the stack or dwelling, according to the operation of the hull, when the outside air around the hull flows toward the stack or dwelling, the outside air blocking wall to block the outside air partly, reducing the flow rate of the outside air It discloses a ship comprising a.

In the present invention, by placing an external air blocking wall that can significantly reduce the flow rate of the outside air through the pre-blocking of the outside air flowing toward the stack or the inlet in front of the stack or dwelling, And the low pressure space generation in the region between the inlet port> is blocked and suppressed in advance, so that the exhaust gas discharged from the stack side is not unnecessarily entrained in the inlet port side under the implementation environment of the present invention. The source side of the ship uses various types of damages caused by the inflow of exhaust gas (e.g., the health deteriorates due to the exhaust gas, the damage of the self living space and the operating space by the exhaust gas, and the contaminated living space and the operating space). Damage that must consume a large amount of manpower and time in order to cause damage to the operation system. It is possible to effectively avoid a large amount of manpower and time required to recover the malfunction of the navigation system.

Hereinafter, with reference to the accompanying drawings, described in more detail the vessel according to the present invention.

As shown in Figure 3, under the implementation environment of the present invention, in the ship 100 (for example, cargo transport ship, passenger transport ship, drilling ship, etc.) side stack 120 on the hull 101, the residence port 130 By quickly proceeding to the destination with various structures such as), it is possible to perform various cargo transportation roles, passenger transportation roles, drilling roles, etc. given to them. In this case, the sailor side responsible for the operation of the hull 11, for example, while closely looking at the control line of sight (L) connecting the steering wheel 131 of the ship hull 101 and the control scale 102 of the hull 101, the navigation of the hull 101 (A control line of sight (L) can of course vary depending on the situation).

At this time, the preceding stack 120 is, for example, in the state arranged in the rear of the hull 101, various exhaust gases Y generated during the operation of the vessel 100 or the hull 101 (for example, odor, soot , Tar, etc.) to the outside of the hull 101, and the residence port 130 adjacent to the stack 120 is provided with a variety of room (Room) of various sizes, the long-term navigation Width of living space for crew members (e.g., crew accommodation room, crew dining room, rest room, etc.) and operating space (e.g., ship steering room, ship engine room, etc.) for the operation of the ship 100 (or hull) It will serve as a broad offering.

Under such a system of the present invention, when the hull 101 of the ship 100 proceeds a certain speed or more in the direction of the arrow A6, the outside air around the hull 101 along the arrow A7 opposite thereto, the hull ( It takes a pattern that flows rapidly in the direction of the stack 120 and the residence port 130 arranged in the rear of the 101 (in this case, the flow speed of the outside air is proportional to the operating speed of the hull 101).

Of course, in this situation, if no action is taken, some of the outdoor air that flows rapidly in the rear direction of the hull 101 will show a mechanical mechanism that passes over the upper part of the residence port 130, and finally, thus introduced Outside air flows into the inlet port 120 and the stack 130 (that is, the tail of the inlet port 13) to form an unnecessary low pressure space in the region B.

In this sensitive situation, as shown in FIG. 3 above, in the present invention, the air barrier wall 200, for example, an air barrier fence 201 is further disposed in front of the stack 120 or the inlet 130. To take action.

Of course, under such an additional arrangement of the outdoor air blocking wall 200, some of the outdoor air that flowed rapidly in the rear direction of the hull 101 along the arrow A7 collides with the air blocking wall 200, and then, along the arrow A8, The mechanical mechanism of moving over the upper part of the blocking wall 200 is shown, and as a result, a series of low pressure spaces may be naturally formed in the rear region K of the external air blocking wall 200.

Naturally, under such pre-formation of the low pressure space, the outside air flowing in the direction of the stack 120 or the inlet port 130 along the arrow A9, due to the formation of the low pressure space mentioned above, the flow rate is significantly higher than in the prior art. As a result, even when the outside air flowing at such a low speed collides with the inlet 130, it does not form an unnecessary low pressure space in the region B between the inlet 120 and the stack 130.

Of course, under such a low-pressure space formation situation, as shown in Figure 4, the various exhaust gas (Y) discharged from the stack 120 side is the area (B) between the inlet 130 and the stack 120 Without being entrained in, it can be quickly discharged to the outside of the hull 101 along the arrow A10.

Perhaps, of course, under such a situation in which the exhaust gas Y is blocked (in a normal discharge situation), the source side using the inlet 130 may cause various damages caused by the large inflow of the exhaust gas Y, for example, exhaust gas. Damage to health deteriorated by (Y), damage to own living space and operating space by exhaust gas (Y), damage to large scale manpower and time to restore the contaminated living space and operating space. It is possible to effectively avoid the damage caused by the malfunction of the navigation device (eg, engine, steering, etc.), and the need to spend a large amount of manpower and time to recover the malfunction of the navigation device, and eventually, the vessel 100 ) Can also enjoy the benefits of greatly improving the overall quality of use of vessels (eg, freight forwarding customers, travelers, shipowners, etc.).

On the other hand, as shown in Figure 5, in applying the above-described present invention to the vessel 100, for example, the problem of <how much height to keep the air blocking wall 200 to maintain> will be raised substantially. It becomes possible.

At this time, in the present invention, as shown in FIG. 5, measures to keep the outside air barrier wall 200 at a height N not exceeding the control line J of the hull 101 are taken.

Of course, when the outside air blocking wall 200 is to maintain the height N not to exceed the control line J of the hull 100, the air blocking wall 200 on the sailor side responsible for the operation of the hull 101 Even under the arrangement situation of, the navigation of the hull 101 is maintained stably while, for example, normally looking at the control line of sight L connecting the steering wheel 131 of the ship hull 101 and the maneuvering scale 102 of the hull 101. You can do it.

On the other hand, as shown in FIG. 5, in applying the present invention described above to the vessel 100, in addition to the above-mentioned <height problem of the air blocking wall 200>, for example, <air blocking wall 200 ) And how much distance L to maintain between the stack 120> can be substantially raised.

In consideration of such a problem, the applicant's side, through a series of experiments, as shown in FIG. 6, the separation distance L between the outside air barrier wall 200 and the stack 120, and the height of the stack D The relationship between the effects on the concentration of the exhaust gas Y in the region B between the housing 130 and the stack 120 was examined in detail.

이 3 이상일 때, 영역 B에 대한 배기가스 집중도가 크게 감소한다는 결과를 확인하였으며, 그에 따라, 외기 차단 벽체(200)의 <연돌(120) 측으로부터의 이격 거리 L>를 하기의 <수학식1>에 맞추어 설계·배치함으로써, 배기가스(Y)의 영역 B로의 불필요한 유입을 최소한으로 차단하였다.As a result of this investigation, the applicant's ratio, as shown in FIG.

When the concentration is 3 or more, it was confirmed that the exhaust gas concentration in the region B is greatly reduced, and accordingly, the distance L from the side of the stack 120 of the air barrier wall 200 is represented by Equation 1 below. By designing and arranging in accordance with>, unnecessary inflow of the exhaust gas Y into the area B was blocked to a minimum.

(L, where L is the separation distance between the stack 120 and the outside air blocking wall 200, D is the height of the stack 120)

이 3 이상이고, 8이하일 때, 영역 B에 대한 배기가스 집중도가 크게 감소한다는 다른 측면의 결과도 확인하였으며, 그에 따라, 외기 차단 벽체(200)의 <연돌(120) 측으로부터의 이격 거리 L>를 하기의 <수학식2>에 맞추어 설계·배치함으로써, 배기가스(Y)의 영역 B로의 불필요한 유입을 최소한으로 차단하였다.In addition, as a result of the above-described investigation of FIG. 6, the applicant's ratio between L and D

Is greater than or equal to 3 and less than or equal to 8, the result of the other aspect that the concentration of exhaust gas in the region B is greatly reduced is also confirmed, and accordingly, the distance <L distance from the side of the stack 120 of the air barrier wall 200>. By designing and arranging according to the following <Equation 2>, unnecessary inflow of the exhaust gas (Y) to the region B was minimized.

(L, where L is the separation distance between the stack 120 and the outside air blocking wall 200, D is the height of the stack 120)

이 5일 때, 영역 B에 대한 배기가스 집중도가 크게 감소한다는 또 다른 측면의 결과도 확인하였으며, 그에 따라, 외기 차단 벽체(200)의 <연돌(120) 측으로부터의 이격 거리 L>를 하기의 <수학식3>에 맞추어 설계·배치함으로써, 배기가스(Y)의 영역 B로의 불필요한 유입을 최소한으로 차단하였다.Furthermore, as a result of the above-described investigation of FIG. 6, the applicant's ratio between L and D

In this case, the results of another aspect that the concentration of the exhaust gas in the region B is greatly reduced are also confirmed. Accordingly, <distance distance L from the stack 120 side of the air barrier wall 200 is By designing and arranging according to <Equation 3>, unnecessary inflow of the exhaust gas Y into the area | region B was cut off to the minimum.

(L, where L is the separation distance between the stack 120 and the outside air blocking wall 200, D is the height of the stack 120)

On the other hand, in the above-described embodiment, the case where the outside air blocking wall 200 is <the outside air blocking fence 201> has been mainly described, but in the present invention, as shown in FIG. It is also possible to flexibly replace the wall 200 with another structure, such as the container stack 202.

Of course, when the air blocking wall 200 is replaced with the container stock 202, the container box normally mounted on the hull 101 does not need to separately install the <air blocking fence 201> on the source side. By being able to easily utilize the air blocking wall 200, it is possible to effectively enjoy the benefits accordingly.

As described above, even when the air blocking wall 200 is replaced with the container stock 202, a part of the outside air that has flowed rapidly in the rear direction of the hull 101 along the arrow A7 collides with the air blocking wall 200. Afterwards, along the arrow A8, a mechanical mechanism is shown to ride over the top of the outside air barrier wall 200, so that a series of low pressure spaces can be naturally formed in the rear region K of the outside air barrier wall 200. .

Naturally, under such pre-formation of the low pressure space, the outside air flowing in the direction of the stack 120 or the inlet port 130 along the arrow A9, due to the formation of the low pressure space mentioned above, the flow rate is significantly higher than in the prior art. As a result, even when the outside air flowing at such a low speed collides with the inlet 130, it does not form an unnecessary low pressure space in the region B between the inlet 120 and the stack 130.

Of course, under the condition of not forming the low pressure space, as shown in FIG. 4, various exhaust gases Y discharged from the stack 12 side are located between the inlet 130 and the stack 120. Without being entrained in (B), along arrow A10, it can be normally discharged to the outside of the hull.

This invention has an overall useful effect in various fields that require the emission of exhaust gas.
