Abstract

La présente invention a pour but de fournir un dispositif d'ajustement de gaz qui est capable d'atténuer les effets de changements de propriété qui accompagnent le mélange d'un premier gaz et d'un second gaz. Pour atteindre ce but, dans ce dispositif d'ajustement de gaz 1 pour ajuster l'état de mélange d'un premier gaz et d'un second gaz, un tuyau d'alimentation en gaz 12 pour fournir le second gaz, et un tuyau d'extraction de gaz 13 pour extraire un gaz d'un récipient de mélange de gaz 11, dans lequel le premier gaz est reçu, sont reliés dans le récipient de mélange de gaz 11. Une buse d'alimentation en gaz tubulaire, mince et longue 14, est disposée à l'intérieur du récipient de mélange de gaz 11. Une pluralité de sections d'évacuation de gaz 15, qui sont des zones dans lesquelles des trous d'alimentation en gaz 151 sont formés, sont disposées de manière distincte. Une chicane 16 est disposée sur le côté aval de l'emplacement auquel la section d'évacuation de gaz 15 sur le côté extrémité de pointe de la buse d'alimentation en gaz 14 est disposé, de façon à bloquer une partie de la section transversale du récipient de mélange de gaz 11.
