Title
(EN) GAS MIXING DEVICE
(FR) DISPOSITIF DE MÉLANGE DE GAZ
(JA) ガス混合装置
Abstract
(EN)
Disclosed is a gas mixing device, wherein component gas flows smoothly into a pipe in which diluent gas flows, without the high-speed, high-flow diluent gas flowing backwards towards the pipe in which the low-speed, low-flow component gas flows, and as a result, the concentration of component gas in the mixed gas can be set as desired in a short time period. The gas mixing device (100) is equipped with a double pipe system (1) comprising an outer pipe (11) in which the diluent gas flows and an inner pipe (12) in which a flow outlet (123) formed at the tip opens to the interior of the aforementioned outer pipe (11) and in which the component gas flows, wherein the aforementioned inner pipe (12) comprises a boundary section (124) connecting a base end (121) and the aforementioned tip (122) and has a step formed on the boundary section (124) of the aforementioned base end (121) and the aforementioned tip (122) in a manner such that the outer wall surface of the aforementioned base end (121) is farther out than the outer wall surface of the aforementioned tip (122).

L'invention porte sur un dispositif de mélange de gaz, dans lequel un gaz constitutif gazeux s'écoule sans à-coup dans un tube dans lequel un gaz diluant s'écoule, sans que le gaz diluant à haut écoulement, à haute vitesse, ne s'écoule en retour vers le tube dans lequel le gaz constitutif à faible vitesse et à faible écoulement s'écoule, et comme résultat, la concentration du gaz constitutif dans le gaz mixte peut être réglée comme désiré en une courte période de temps. Le dispositif de mélange de gaz (100) est équipé d'un système à double tube (1) comprenant un tube externe (11) dans lequel le gaz diluant s'écoule et un tube interne (12) dans lequel une sortie d'écoulement (123) formée à l'extrémité s'ouvre vers l'intérieur du tube externe mentionné ci-dessus (11) et dans lequel le gaz constitutif s'écoule, le tube interne mentionné ci-dessus (12) comprenant une section limite (124) reliant une extrémité de base (121) et l'extrémité mentionnée ci-dessus (122) et a un étage formé sur la section limite (124) de l'extrémité de base mentionnée ci-dessus (121) et de l'extrémité mentionnée ci-dessus (122) d'une manière telle que la surface de paroi externe de l'extrémité de base mentionnée ci-dessus (121) s'étend plus loin que la surface de paroi externe de l'extrémité mentionnée ci-dessus (122).

 低流量、低流速の成分ガスが流れる配管に対して、大流量、高流速の希釈ガスが逆流等することなく、スムーズに成分ガスが希釈ガスの流れる配管に流れ込み、その結果、短時間で混合ガスにおける成分ガスの濃度を所望のものとすることができるようになるガス混合装置であって、希釈ガスが流れる外部配管11と、先端に形成された流出口123が前記外部配管11の内部に開口し、成分ガスが流れる内部配管12と、からなる二重配管1を備えたガス混合装置100であって、前記内部配管12が、前記基端部121と前記先端部122とを接続する境界部124と、からなり、前記基端部121と前記先端部122の境界部124において、前記基端部121の外壁表面が前記先端部122の外壁表面よりも外側となるように段差を形成した。
