Description

[0001] The present invention relates to an upper structure of a funnel for a ship,

The present invention relates to an upper structure of a funnel for a ship for protecting a smoke exhaust pipe. More specifically, a bulwark capable of collecting the flow of air to the stern side is formed, and air A flap having a slope toward the rear is formed on the rear side of the stern side and an upper bottom surface of the stern side is formed so as to be inclined at a lower side so that the exhaust gas discharged from the exhaust pipe is dropped on the ship And to the superstructure of the ship's funnel which prevents contamination of the ship and loaded cargo or harming the crew.

Generally, diesel engines are mainly used in ships, and the propulsive power required by ships is obtained through the use of diesel engines. In addition, various equipments and devices are mounted on the ship, and driving means for driving them are also mounted.

Thus, in order to drive various facilities installed in the ship, air supply is required, and the supplied air is used for combustion and then discharged to the atmosphere together with the exhaust gas. At this time, a funnel facility is provided around the stern portion of the ship as a means for exhausting the exhaust gas generated at the time of discharge of the air and combustion.

As shown in FIG. 1A, in the conventional funnel equipment, a smoke pipe apparatus of the prior art is provided with a smoke exhaust pipe 1 protruding upward from the upper surface of a funnel 10, and an upper part of the funnel 10 is surrounded (Not shown) for treating the air inside the funnel 10 are provided in addition to the hand rails.

As shown in FIG. 1B, inflow air is supplied to various parts installed in the engine room, such as an engine room, a main engine, a diesel generator, a boiler, and an incinerator, as schematically shown in FIG. After being processed, the exhaust smoke is discharged to the outside of the ship through the exhaust pipe (1) of each equipment.

At this time, since no smoke preventing means is provided to prevent the smoke from flying far away and stagnating around the hull, the smoke discharged from the exhaust pipe 1 is stagnated around the hull as shown in Fig. And there was a problem that the ship and the cargo were contaminated or the passenger returned to the entrance of the fan room to damage the crew and the like.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to solve the above problems, and it is an object of the present invention to provide an air conditioner, And to provide a superstructure of a ship funnel which does not harm the crew or the like.

In order to achieve the above object, the present invention provides an upper structure (10a) for a ship funnel (10) for protecting a smoke exhaust pipe (1) Wherein a bulwark (11) capable of collecting the flow of air to the stern side is formed in order to induce the air to flow away without falling on the ship.

At this time, it is preferable that an air inflow hole 12 through which air can flow in front of the forward side is formed so that an upwind due to the progress of the ship may be introduced, and the air inflow hole 12 may be a handrail type An opening type, or the like. In order to increase the amount of air introduced into the air inflow hole 12, a reflux device may be additionally provided in front of the forward side.

In order to induce the air introduced from the air inflow hole 12 to fly away without falling to the stern, a flap 13 having a slope toward the rear may be formed on the rear side of the stern, In order to increase the strength of the upward flow generated while passing through the flap 13, it is preferable that an air nozzle is additionally provided behind the stern.

It is preferable that the upper floor 14 has a structure in which the forward side is inclined lower so that the air introduced from the air inflow hole 12 passes through the flap 13 to form a rising air flow.

As described above, in the upper structure of the ship funnel according to the present invention, a bulwark capable of collecting the flow of air to the stern side is formed, an air inflow hole through which air can flow in front of the forward side is formed, So that the smoke discharged from the exhaust pipe is not stagnated around the hull and flows naturally to the outside of the ship with the flow of air. It can prevent the problem of flying away and polluting the ship and the cargo or hurting the crew.

2A and 2B are cross-sectional views showing a funnel (FIG. 2A) and a smoke flow (FIG. 2B) in a ship structure according to the present invention.
3 is a sectional view of a funnel top structure of a ship according to the present invention.
4 is a plan view of the funnel upper structure of a ship according to the present invention.
FIGS. 5A and 5B are front views showing a front side of a bow formed with an air inflow hole according to the present invention, showing a handrail type and an opening type.
6 is a partial cross-sectional view showing the flow of air passing through the upper floor surface of the funnel upper structure and the flaps according to the present invention.
7 is a conceptual view showing the flow of air and smoke when the funnel upper structure of the present invention is applied to a ship.

Hereinafter, an upper structure of a ship funnel according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an upper structure (10a) of a funnel (10) for a ship for protecting a smoke exhaust pipe (1), in which smoke emitted from the exhaust pipe (1) A bulwark 11 capable of collecting the flow of air to the stern side is formed.

As shown in Fig. 1A, the conventional funnel equipment is provided with only a handrail which is open at the top and surrounds the upper part of the funnel 10, so that the smoke discharged through the exhaust pipe 1 I could not fly far to the top and I had to stagnate around the hull. Accordingly, in the present invention, the handrail can be replaced with a bulwark made of an iron plate or the like, thereby collecting wind.

At this time, it is preferable that an air inflow hole 12 through which air can flow in front of the forward side is formed on the upper part of the funnel 10 so that a forward wind due to the progress of the ship can flow smoothly. The air inflow hole 12 may be applied in various forms. However, the air inflow hole 12 may be a handrail type or an opening type as shown in FIGS. 5A and 5B.

Further, a reflux device (not shown) may be additionally provided in front of the forward side in order to further increase the amount of air introduced into the air inflow hole 12 as necessary.

On the other hand, as shown in FIG. 6, in order to induce the air introduced from the air inflow hole 12 to fly far above the ship without dropping directly to the stern, a flap 13). At this time, in order to increase the strength of the upward flow generated while passing through the flaps 13 according to the selection, an upward flow increasing device such as an air nozzle (not shown) .

The air nozzle may be formed integrally or adhered to the flap 13, and it is general that the inflow portion into which air flows is wide and the discharge portion from which air is discharged has a narrow structure. In addition, the inclination angle of the discharge portion is more sharply inclined than the inclination of the flap 13 so as to upwardly discharge the air, so that the smoke discharged from the funnel 10 is guided further upward to block access to the ship can do.

In addition, it is preferable that the upper floor 14 has a structure in which the forward side is inclined so that the air introduced from the air inflow hole 12 passes through the flaps 13 and forms a rising airflow. Through this structure, as shown in FIG. 7, when the ship moves forward, the air introduced through the air inflow hole 12 takes up the slope of the upper floor 14 and the flap 13 disposed at the rear side It is possible to prevent the smoke from stagnating on the ship by raising the smoke discharged through the exhaust pipe 1 while forming an ascending air flow.

Through the above-described construction, the smoke discharged from the exhaust pipe of the present invention can be flown away from the ship with the flow of air naturally without being stagnant around the hull.

The present invention is not limited to the above-described specific embodiments and descriptions, and various modifications can be made to those skilled in the art without departing from the gist of the present invention claimed in the claims. And such modifications are within the scope of protection of the present invention.
