【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、船尾部に煙突（排気管）が設けられている船
舶の船尾煙害防止装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a stern smoke pollution control device for a ship having a chimney (exhaust pipe) at the stern.
客船やレストラン船、遊覧船等では、乗客や乗員に及ぼ
す煙害を防止する目的から、煙突を船尾部に設置する例
が多い。In passenger ships, restaurant ships, sightseeing boats, etc., there are many cases in which a chimney is installed at the stern of a ship for the purpose of preventing smoke damage to passengers and crew.
第６図は船尾部に設けられた煙突の一例を示すもので、
船尾部１において、船体上部構造２よりも後方に煙突３
が装備され、その煙の排出方向は矢印４で示すように後
方へ向けられている。なお、図中の符号５は船の進行方
向を示し、６は風の方向、７は後流渦を示す。FIG. 6 shows an example of a chimney provided in the stern,
In the stern part 1, the chimney 3 is located behind the upper structure 2 of the hull.
Is installed, and the smoke emission direction is directed rearward as indicated by arrow 4. In the figure, reference numeral 5 indicates a traveling direction of the ship, 6 indicates a wind direction, and 7 indicates a wake vortex.
船の進行につれて風が矢印６の方向に流れると、船体上
部構造２の後流側に後流渦７が発生するが、煙突３より
矢印４の方向に排出された煙は、上方へ流れて上述の後
流渦７に巻込まれるようになる。When the wind flows in the direction of arrow 6 as the ship progresses, a wake vortex 7 is generated on the wake side of the hull upper structure 2, but the smoke discharged from the chimney 3 in the direction of arrow 4 flows upward. It comes to be caught in the above-mentioned wake vortex 7.
第６図に示すように船尾部１に煙突３が装備された場
合、同煙突３からの排気ガス（煙）の排出速度は10m/S
程度にされているが、図示のごとく船体上部構造２の後
方に後流渦７が発生し、これに煙突３より排出された煙
が巻込まれて、乗客、乗員および船体が煙害に晒される
という問題点がある。When the stern 1 is equipped with a chimney 3 as shown in FIG. 6, the exhaust gas (smoke) discharge speed from the chimney 3 is 10 m / S.
However, as shown in the figure, a wake vortex 7 is generated behind the upper hull 2 of the ship, and the smoke discharged from the chimney 3 is entrained in the vortex 7, causing passengers, passengers, and the hull to be exposed to smoke damage. There is a problem.
本考案は、上述のような問題点の解決をはかろうとする
もので、導風板を適切に配設することにより船尾部にお
ける煙害を防止できるようにした装置を提供することを
目的とする。The present invention is intended to solve the above problems, and an object thereof is to provide a device capable of preventing smoke damage in the stern by appropriately disposing a baffle plate. .
上述の目的を達成するため、本考案の船尾煙害防止装置
は、船尾部において、船尾端に装備された煙突の上方を
蔽う平板状の導風板をそなえ、同導風板が、その板面に
沿う空気流を同板面と平行に後方へ導くべく、船尾端か
ら後方へ突出し後縁を開放されるようにしてほぼ水平に
設置されていることを特徴としている。In order to achieve the above-mentioned object, the stern smoke pollution control device of the present invention is provided with a flat baffle plate overlying a chimney installed at the stern end at the stern part, and the baffle plate has its plate surface. In order to guide the air flow along the rearward parallel to the plate surface, it is characterized by being installed almost horizontally with the rear edge protruding and protruding rearward from the stern end.
上述の本考案の船尾煙害防止装置では、平板状の導風板
が船尾端の煙突（排気管）の上方を蔽いながら船尾端か
ら後方へ突出するように設置され、しかも導風板の後縁
は開放されているので、導風板に沿う空気流が板面と平
行に後方へ導かれるようになり、その空気流により導風
板下方の煙突からの煙は遮断されるようになる。In the stern smoke pollution control device of the present invention described above, the flat baffle plate is installed so as to cover the upper part of the chimney (exhaust pipe) at the stern end and to project rearward from the stern end, Since the edge is open, the air flow along the baffle plate is guided rearward in parallel with the plate surface, and the air flow blocks the smoke from the chimney below the baffle plate.
したがって、船体上部構造の後方に後流渦が発生して
も、その後流渦に煙突より出る煙が巻込まれることはな
く、船尾部における煙害が防止されるようになって、船
は快適な航行を持続することができる。Therefore, even if a wake vortex is generated behind the superstructure of the hull, the smoke generated from the chimney is not entrained in the wake vortex, and the smoke damage at the stern is prevented, and the ship is comfortable to navigate. Can last.
以下、図面により本考案の一実施例としての船尾煙害防

は、十分に防止されるのである。As described above, the flat baffle plate 8 covering the chimney 3 is installed substantially horizontally so as to project rearward from the stern end and open the trailing edge (that is, no bulwark or the like is erected on the trailing edge). By doing so, the air flow along the plate surface of the baffle plate 8 is guided rearward in parallel with the plate surface, so that the smoke from the chimney 3 below the baffle plate 8 is blocked by the air flow. become. Therefore, the phenomenon in which the smoke from the chimney 3 is entrained in the wake vortex (see reference numeral 7 in FIG. 6) in the stern portion as in the conventional case is sufficiently prevented.
本実施例の実験例では、導風板８の船尾部１後端部から
後方への突出長さは約2m、煙突３と導風板８との距離も
ほぼ2mとされたが、煙害は認められなかった。In the experimental example of this example, the protruding length of the baffle plate 8 from the rear end of the stern portion 1 to the rear was about 2 m, and the distance between the chimney 3 and the baffle plate 8 was about 2 m, but the smoke damage was I was not able to admit.
