Abstract

Foreliggende oppfinnelse tilveiebringer en smeltesalt elektrolysecelle for fjerning av kalsiumklorid inneholdende kalsium som blir brukt for reduksjon av et oksid eller klorid av titan, spesielt en smeltesalt elektrolysecelle som kan gjenvinne kalsiumklorid ved smeltesaltelektrolyse ved høy effektivitet. Smeltesalt elektrolysecellen innbefatter en beholder, som inneholder et smeltet saltbad og har et lokk på sin øvre del, en anode og en katode som er forlenget gjennom lokket fra ovenfra beholderen og er nedsenket og beliggende i smeltesaltbadet, en trykkreduserende anordning forbundet med katoden, en gasstilførselsdyse for tilførsel av gass fra utsiden av beholderen inn i beholderen, en gassutløpsdyse for utslipp av gass fra innsiden av beholderen til utsiden av beholderen, og en smeltesalt tilførselsdyse for mating av et smeltet salt fra utsiden av beholderen inn i beholderen. Katoden er hul. Et finnelegeme er forbundet med den ytre overflaten av katoden. Rett over det sammenføyde partiet mellom katoden og finnelegemet, er det tilveiebrakt et gjennomgående hull i katoden.The present invention provides a melt salt electrolysis cell for removing calcium chloride containing calcium which is used to reduce an oxide or chloride of titanium, in particular a melt salt electrolysis cell which can recover calcium chloride by high salt melt electrolysis. The melt salt electrolytic cell includes a container which contains a molten salt bath and has a lid on its upper part, an anode and a cathode which is extended through the lid from above the container and is immersed and located in the melt salt bath, a pressure reducing device connected to the cathode, a gas supply nozzle. for supplying gas from the outside of the container into the container, a gas outlet nozzle for discharging gas from inside the container to the outside of the container, and a melting salt supply nozzle for feeding a molten salt from the outside of the container into the container. The cathode is hollow. A fin body is connected to the outer surface of the cathode. Directly over the joined portion between the cathode and the fin body, a through-hole is provided in the cathode.
