(EN) DEVICE FOR HUMIDIFYING A GAS
(FR) DISPOSITIF POUR HUMIDIFIER UN GAZ
Abrégé
(EN)
In a gas-to-gas humidifier (10) the active membrane surface area, by way of which waste gas supplied to the gas-to-gas humidifier releases moisture to air to be humidified, is controlled. This is possible in particular continuously by using a slide (24), which covers a portion of the inlets (20) of the passages (16). By the position of the slide (24), the humidity level of the air to be humidified by the gas-to-gas humidifier (10) may be defined. Owing to the use of a slide (24) or another mechanical adjusting element, which directly covers inlets (20) or outlets of passages, the gas-to-gas humidifier (10) is of particularly compact construction and thus takes up only a small amount of space, at the same time being inexpensive.
(FR)
Dans un humidificateur gaz-gaz (10), on contrôle la surface de la membrane active au moyen de laquelle le gaz d'échappement amené à l'humidificateur gaz-gaz libère l'humidité dans l'air qui doit être humidifié. Cela est possible en particulier en continu en utilisant une coulisse (24), qui couvre une partie des entrées (20) des passages (16). Grâce à la position de la coulisse (24), le niveau d'humidité de l'air qui doit être humidifié par l'humidificateur gaz-gaz (10) peut être défini. Grâce à l'utilisation d'une coulisse (24) ou d'un autre élément d'ajustement mécanique, qui couvre directement les entrées (20) ou les sorties des passages, l'humidificateur gaz-gaz (10) a une construction particulièrement compacte et occupe donc peu d'espace, tout en étant peu onéreux.
