Abstract[English]
Provided is a vacuum exhaust system (10) that can send exhaust gas and diluent gas to a predetermined location while maintaining a constant temperature without lowering a temperature of the exhaust gas and the diluent gas as much as possible. The vacuum exhaust system (10) includes: a gas exhaust pipe (14) that is connected to a subsequent stage of a vacuum pump (12) and has a vacuum heat insulating pipe structure with a vacuum layer (21) between an inner pipe (19), through which used gas (G1) discharged from the vacuum pump (12) passes, and an outer pipe (20) surrounding the inner pipe (19); and a diluent gas introduction pipe (24) that introduces diluent gas (G2) for heating the used gas (G1) into the inner pipe (19) so that the used gas (G1) is maintained in a gaseous state in the gas exhaust pipe (14).[French]
L'invention concerne un système d'échappement sous vide (10) qui peut envoyer des gaz d'échappement et un gaz diluant vers un emplacement prédéterminé tout en maintenant une température constante sans abaisser autant que possible la température des gaz d'échappement et du gaz diluant. Le système d'échappement sous vide (10) comprend : un tuyau d'échappement de gaz (14) qui est raccordé à un étage ultérieur d'une pompe à vide (12) et a une structure de tuyau d'isolation thermique sous vide avec une couche sous vide (21) entre un tuyau interne (19), à travers lequel passe le gaz usagé (G1) évacué de la pompe à vide (12), et un tuyau externe (20) entourant le tuyau interne (19) ; et un tuyau d'introduction de gaz diluant (24) qui introduit un gaz diluant (G2) pour chauffer le gaz usagé (G1) dans le tuyau interne (19) de sorte que le gaz usagé (G1) est maintenu dans un état gazeux dans le tuyau d'échappement de gaz (14).
