う。 As shown in Fig. 6, the pressure inside the chimney 1 is higher than the atmospheric pressure on the atmosphere side (C is a line showing the atmospheric pressure) at the top A side of the chimney 1.
At the lower part B, the pressure is lower than the atmospheric pressure on the atmospheric side.
Therefore, the exhaust gas ○I flows back into the rainwater discharge gutter 5 provided at the side of the top A of the chimney 1, and the exhaust gas ○I blows out to the atmosphere from the side exhaust pipe 6 and surrounds the chimney 1. It can get dirty or corrode.

い。 Exhaust gas containing corrosive gases HCl and SO 4 is
When passing through the side drain pipe 6, it is cooled by the atmosphere and turns into a corrosive liquid such as HCl or H 2 SO 4 , which significantly corrodes the metal rain gutter 5 and side drain pipe 6. Furthermore, the joint between the main body of the chimney 1 and the rain gutter 5 may also be affected by this and corrode. For this reason, it is conceivable to use FRP, vinyl chloride, or the like, which can withstand corrosive liquids, as a material for the rain gutter 5, etc., but these materials cannot withstand the high temperature of the exhaust gas. Therefore, the rain gutter 5 and the side drain pipe 6 cannot be made permanent and must be repaired every short period of time.

22 and 23 are the main body and top of the chimney 20.
The top part 23 of the chimney has a bent dogleg shape, and 2
It consists of an upper part, a central part, and a lower part indicated by 5, 24, and 26. Note that the opening 25a of the upper part 25 and the lower part 2
The horizontal projection planes of the openings 26a provided above 6 are arranged so as not to overlap with each other. A cap 27 is attached to the upper edge of the chimney top 23 to protect it. A lining 28 is provided inside the chimney 20 over the chimney body 22 and the chimney top 23. The atmosphere side of the chimney body 22 is covered with an outer cylinder steel plate 29, and the outside of the chimney top 23 is covered with a nozzle steel plate 30. 31 is the center part 24 of the chimney top 23
It is a ring-shaped rain gutter attached so as to divide the inside in the vertical direction, and a vertical gutter shown at 32 is provided at the bottom to allow rainwater to flow down along the inner wall.
上記のように構成された煙突20においては、

る。 In the chimney 20 configured as described above,
The inner wall of the upper part 25 and the inner wall of the central part 24 of the chimney top 23 will catch all the rainwater that falls,
The rain gutter 31 collects and discharges this rainwater. Therefore, the chimney top 23 can prevent rainwater from entering into the chimney body 22.
以上の説明から明らかなように本考案によれば
次のような顕著な効果を挙げることができる。
As is clear from the above description, according to the present invention, the following remarkable effects can be achieved.
煙突内部に竪樋が設けられているために排ガ
スは常に煙突から排出され、外部に漏れるなど
のおそれはない。 Because the chimney is equipped with a pipe, exhaust gas is always discharged from the chimney and there is no risk of it leaking outside.
竪樋が常に排ガス温度同等に保たれるため
に、竪樋に侵入した排ガスは結露することがな
く、このため竪樋は腐食することがない。 Since the downpipe is always kept at the same exhaust gas temperature, the exhaust gas that has entered the downpipe does not condense, and therefore the downpipe does not corrode.
竪樋の継手はサヤ管は竪樋内部に設けてある
ため雨水の煙突内部への侵入のおそれがなく、
また温度の変化に対応して伸縮することができ
る。 Since the pipe fittings are installed inside the pipe, there is no risk of rainwater entering the chimney.
It can also expand and contract in response to changes in temperature.
排水管を煙突基礎のコンクリート部などに設
けたので外部から冷却され排ガスによる高温度
の影響を受けにくい。このため排水管内部に侵
入した排ガスは結露し、腐食性液体になるおそ
れがあるが、しかし排水管はFRP、塩化ビニ
ルなど十分に耐食性のある材料で設けてあるた
め腐食することはない。 Since the drain pipe is installed in the concrete part of the chimney foundation, it is cooled from the outside and is less susceptible to the high temperatures caused by exhaust gas. For this reason, the exhaust gas that enters the drain pipe may condense and become a corrosive liquid, but the drain pipe is made of sufficiently corrosion-resistant materials such as FRP and vinyl chloride, so it will not corrode.
本考案によれば、恒久的な使用が可能とな
り、従来のような短期間毎の保守点検が不要と
なる。 According to the present invention, it is possible to use it permanently, and there is no need for maintenance and inspection every short period as in the past.
