水室５内へダウンドラフトされる。Next, the operation of the present embodiment will be described. When the inside of the duct 10 is sucked from the suction device 19, the fume of the worktable 1 enters the branch pipe 4 from the suction port 3 of the hood 2 and is downdraft into the water storage chamber 5.
【００４２】このため、粉塵等のうち重量の大きなもの
は大部分が慣性分離されて水９中へ捕捉され、残りの粉
塵等を含むヒュームは排煙出口８方向へ向きを変えて水
面上を移動する。For this reason, most of the heavy dust among the dust and the like is separated into the water 9 by inertia separation, and the fume including the remaining dust and the like is turned in the direction of the flue gas outlet 8 and rises above the water surface. Moving.
【００４３】このヒュームは、排煙出口８の近傍で、遮
蔽板１２に衝突して斜め下向きに方向を変えられ、この
段階でさらに多くの粉塵等が慣性分離されて水中へ捕捉
される。The fume collides with the shielding plate 12 in the vicinity of the smoke exhaust outlet 8 and is turned obliquely downward. At this stage, more dust and the like are inertially separated and captured in the water.
【００４４】ここでもまだ分離されずに残った比較的微

え、吸引装置１９の吸引能力も十分に大きなもになって
いる。At this time, the air moving in the water storage chamber 5 toward the smoke exhaust outlet 8 is throttled in a narrow space between the tip of the shielding plate 12 and the water surface, and further narrowed in the smoke exhaust outlet 8. In addition, the suction capacity of the suction device 19 is sufficiently large.
【００４６】このため、貯水室５内部の遮蔽板１２で区

へ大量に吸引される。For this reason, the negative pressure is partially increased in the vicinity of the smoke discharge outlet 8 defined by the shielding plate 12 inside the water storage chamber 5, and the water 9 in the water storage chamber 5 is reduced in the lower part of the smoke discharge outlet 8. Is swirled by suction on the suction device 19 side, and a part of the water surface is atomized and sucked into the duct 10 together with the fume in a large amount.
【００４７】これにより、ダクト１０内は常時高湿度に
維持され、粉塵等がブース１４などのコーナー部分等へ
堆積しても、この湿度により湿った状態に維持される。As a result, the inside of the duct 10 is constantly maintained at a high humidity, and even if dust or the like accumulates at the corners of the booth 14 or the like, the humidity is maintained at this humidity.
【００４８】そこで、作業台１で発生した溶接スパッタ
などが吸入口３からダクト１０内へ吸引されても、水分
により冷却される。Therefore, even if welding spatter or the like generated on the work table 1 is sucked into the duct 10 from the suction port 3, it is cooled by moisture.
【００４９】そのうえ、図３に示すように、ブース１４

し、水溜まり状になっている。In addition, as shown in FIG.
Is provided with a secondary water storage section 20. A part of the water that has moved upward from the water storage chamber 5 is dropped into the inside of the secondary water storage section 20 to form a water pool.
【００５０】二次貯水部２０に溜まった水は、その下流
側へ随時吸引されてダクト内を高湿度に保つように水分
を補給し、特にダクト内が乾燥してくると速やかに加湿
するように作用する。The water stored in the secondary water storage section 20 is sucked to the downstream side as needed to replenish the water so as to keep the inside of the duct at a high humidity. In particular, the water is humidified quickly when the inside of the duct becomes dry. Act on.
【００５１】ゆえに、ダクト１０が長くなったり、複雑
に屈曲している場合でも、ダクト内全体の湿度を平均化
するために役立っている。Therefore, even when the duct 10 is long or bent in a complicated manner, it is useful for averaging the humidity in the entire duct.
【００５２】さらに、ダクト１０を屈曲配管するための
ブース１４内を利用することにより、その内部に二次貯
水部２０を容易に設けることができる。Further, by using the inside of the booth 14 for bending and ducting the duct 10, the secondary water storage section 20 can be easily provided therein.
【００５３】この二次貯水部２０の位置は、必ずしもブ

クト１０内の適宜位置でも良い。The position of the secondary water storage section 20 is not necessarily limited to the inside of the booth 14 but can also be set to the inside of the booth 15 as described above. good.
【００５４】しかも、このブース１４は屈曲したダクト
１０を複数の直管（１３、１５）で構成できるので、粉
塵等を内部へ堆積しにくくできる。Further, in the booth 14, since the bent duct 10 can be constituted by a plurality of straight pipes (13, 15), dust and the like can hardly be deposited inside.
【００５５】このように、本排煙ダクト装置によれば、
