Abstract

Et apparat for oppsamling og fjerning av gass sendt ut av en aluminium reduksjonscelle er formet innenfor en anodesuperstruktur som har to sidevegger i avstand fra hverandre. I det minste en gasstransportkanal som har et varierende tverrsnitt strekker seg langs superstrukturen mot en ende av denne assosiert med et gassbehandlingssystem. Et flertall av gassinngangsseksjoner er anordnet innenfor superstrukturen og formet med et par av andre medlemmer som er i avstand fra hverandre som strekker seg på tvers av sideveggene. I det minste en dyse er formet i et grensesnitt mellom gasstransportkanalen og den respektive gassinngangsseksjonen. Forholdet mellom tverrsnittsområdet til dysen ved en utgang av denne i forhold til et tverrsnittsseksjonsornråde til gasstransportkanalen og utgangen av dysen minker i retningen av enden til gasstransportkanalen assosiert med gassbehandlingssystemet.An apparatus for collecting and removing gas emitted from an aluminum reduction cell is formed within an anode superstructure having two side walls spaced apart. At least one gas transport channel having a varying cross section extends along the superstructure towards one end thereof associated with a gas treatment system. A plurality of gas entry sections are arranged within the superstructure and formed with a pair of other members spaced apart extending across the sidewalls. At least one nozzle is formed in an interface between the gas transport channel and the respective gas inlet section. The relationship between the cross-sectional area of the nozzle at an outlet thereof relative to a cross-sectional area of the gas transport channel and the exit of the nozzle decreases in the direction of the end of the gas transport channel associated with the gas treatment system.
