Description

Ship and ship board exhaust system thereof
Technical Field
The invention relates to a ship and a ship board exhaust system thereof.
Background
The exhaust system of the ship engine adopts a ship board exhaust type, not only saves a chimney structure, but also has the advantages of saving space, reducing the wind-exposed area of an upper building and stabilizing the ship, and is particularly suitable for law enforcement official business ships, such as a sea police ship, a sea prison ship and the like. However, when a ship employs a side exhaust system, it is necessary to prevent rough sea conditions or outboard water caused by other causes (e.g., other ships traveling faster sideways) from entering the engine through the side exhaust system, causing engine failure or damage.
At present, the ship board exhaust system for preventing the outboard water from entering the engine mainly comprises two systems, one system is to add a baffle inside an exhaust pipe, but the ship board exhaust system not only increases the back pressure of the exhaust pipe; and because the exhaust pipe has movable parts, the engine is easy to damage or block due to rusting and corrosion after the exhaust pipe is frequently contacted with seawater for a long time, so that the engine cannot work normally.
The other method is that a control valve is additionally arranged in the exhaust pipe, and the exhaust system is isolated from the outside seawater when the engine does not work. For example, chinese utility model patent with publication number CN202628242U discloses a ship board exhaust system, which comprises a combination piece, a silencer, a short wave-proof pipe and an exhaust box, wherein one end of the short wave-proof pipe is connected with the exhaust box, the short wave-proof pipe is provided with an outer ship-discharging valve, and the outer ship-discharging valve is a pneumatic remote control valve for isolating the exhaust system from the external seawater when the engine is not in operation. However, in this ship side exhaust system, the control valve is closed to prevent the entry of the outboard water into the exhaust pipe, which makes the structure complicated and the response slow.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
The first specific embodiment of the broadside exhaust system of the present invention, as shown in fig. 1, includes an exhaust pipe 3, an inside nozzle of the exhaust pipe 3 is connected to an exhaust port of the engine 2, and an outside nozzle of the exhaust pipe 3 extends outward to the broadside plate 1 for discharging the exhaust gas generated by the engine 2.
The lower side of the exhaust pipe 3 near the side plate is connected with a water collection tank 6 for collecting the outboard water entering the exhaust pipe 3. Referring to fig. 2, a water outlet pipe 7 communicated with the water collecting tank 6 is arranged on the outer side of the tank bottom of the water collecting tank 6, a guide pipe 8 is welded on the upper edge of a water inlet of the water outlet pipe 7 in the water collecting tank 6, and the guide pipe 8 is vertically arranged. The guide pipe 8 is provided with a floating ball 9 for sealing the water outlet pipe at the opening edge of the water inlet of the water outlet pipe, and it can be understood that the average density of the floating ball 9 is less than that of water. The position of the floating ball 9 on the water outlet pipe forms a sealing position for plugging the water outlet pipe, the floating ball 9 can move up and down in the guide pipe 8, and the movement stroke of the floating ball 9 forms the deblocking stroke for deblocking the water outlet pipe. The lower side of the guide pipe 8 has a communication hole 10 penetrating the outer wall for communicating the water collection tank 6 and the guide pipe 8. The intercommunicating pore 10 has a plurality of, and a plurality of intercommunicating pores 10 all vertically arrange, and a plurality of intercommunicating pores 10 are at 8 outer wall circumference equipartitions of stand pipe.

In this embodiment, the pipe diameter of the guide pipe 8 is slightly larger than the diameter of the floating ball 9, so that the floating ball 9 floats up and down along the guide pipe 8. The upper end of the guide pipe 8 is open, and in order to prevent the floating ball 9 from falling off the guide pipe 8 when moving upwards, a baffle plate 12 extending in the radial direction is welded at the upper end of the guide pipe 8.
The bottom of the water collecting tank 6 is provided with a water outlet at the outer side of the guide pipe 8, and the water outlet is in threaded connection with a plugging cap 11. The bottom of the water collecting tank 6 is provided with a water outlet, which is convenient for discharging water and sediments in the water collecting tank 6.
The exhaust pipe 3 is connected with a silencer 4 in series at the inner side of the water collecting tank 6, the silencer 4 in the embodiment is a silencer for a ship, and the silencer is arranged to help to reduce noise in a cabin and increase riding comfort.

The outer sleeve is provided with a water inlet and a water outlet, and the water in the annular space of the outer sleeve and the inner sleeve cools the tail gas of the engine in the inner sleeve.
The working principle of the ship side exhaust system is as follows: under normal working conditions, tail gas of the engine is discharged through the exhaust pipe 3, and the floating ball 9 blocks the water inlet of the water outlet pipe 7 at the moment, so that the tail gas of the engine is prevented from entering the cabin through the water outlet pipe 7. When the outboard water caused by severe sea conditions or other reasons enters the exhaust pipe 3, the outboard water in the exhaust pipe 33 flows into the water collecting tank 6, the water in the water collecting tank 6 enters the guide pipe 8 through the communicating hole 10, the floating ball 9 in the guide pipe 8 moves upwards under the action of buoyancy to open the water inlet of the water outlet pipe 7, and the water is discharged from the water outlet pipe 7, so that the condition that the outboard water enters the engine to influence the normal use and the running safety of the engine is avoided. When the water in the water collecting tank 6 is completely discharged, the floating ball 9 blocks the water inlet of the water outlet pipe 7 again, and the tail gas of the engine is prevented from entering the cabin through the water outlet pipe 7.
As shown in fig. 3 and 4, the second embodiment of the broadside exhaust system of the present invention is different from the first embodiment of the broadside exhaust system in that in the present embodiment, a water outlet pipe 7 is connected to a wall of the water collection tank 6, the water outlet pipe 7 horizontally extends into the water collection tank 6, and one end of the water outlet pipe 7, which is away from the water collection tank 6, vertically extends to the lower side of the water collection tank 6. One end of the water outlet pipe 7 positioned in the water collecting tank 6 is sealed, the upper side of the water outlet pipe is provided with a water inlet, and the guide pipe 8 is welded on the opening edge of the water inlet of the water outlet pipe.
In use, when water in the water collection tank 6 rises to the communication holes of the guide pipe 8, the water in the water collection tank 6 starts to enter the guide pipe 8. That is, the water collecting tank 6 in the present embodiment can store a part of the water.
The specific embodiment of the ship comprises an engine and a ship side exhaust system connected to an engine smoke exhaust port, and the ship side exhaust system in the embodiment has the same structure as the ship side exhaust systems in the embodiments, and is not described in detail.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
