Abstract

Fremgangsmåte og anordning for å trekke ut mer varme fra elektrolyseceller for produksjon av aluminium, med den hensikt å kompensere for den ekstra varmen som produseres i cellen når strømstyrken økes, samt å dissipere mindre varme til rågassen fra cellen. En anodekonstruksjon i cellen innbefatter anodestammen (1) som er koblet til anodebjelken (2) og anodeåket (3) som får elektrisk kontakt med en karbonanode (5) gjennom boltene (4). Anodestammen kjøles ved å øke overflatearealet til stammen over overbygningen (6) til cellen eller ved å bruke et kjølemedium som sirkulerer langs stammen. Kjølingen av anoden kan kombineres med å bruke et varmeisolerende materiale (7) på anodestammen nedenfor overbygningen.Method and apparatus for extracting more heat from electrolysis cells for aluminum production, with the intention of compensating for the extra heat produced in the cell as the current is increased, as well as dissipating less heat to the raw gas from the cell. An anode structure in the cell includes the anode stem (1) which is connected to the anode beam (2) and the anode yoke (3) which is electrically contacted by a carbon anode (5) through the bolts (4). The anode strain is cooled by increasing the surface area of the stem over the superstructure (6) of the cell or by using a refrigerant circulating along the stem. The cooling of the anode can be combined with the use of a heat insulating material (7) on the anode trunk below the superstructure.
