Abstract:
1. A mercury recovery apparatus that recovers mercury from mercury-containing phosphor powder, comprising: a reaction vessel; a distillation vessel that is set in the reaction vessel and in which the mercury-containing phosphor powder is placed; heating means for heating the distillation vessel; and mercury collection means for condensing vaporized mercury by cooling, to collect the vaporized mercury, the vaporized mercury having been vaporized from the mercury-containing phosphor powder in the distillation vessel heated by the heating means, wherein the distillation vessel includes a heat conductive member that is placed so as to come in contact with a part of an interior wall of the distillation vessel, the heat conductive member being for transmitting heat to middle portions of the phosphor powder within the distillation vessel.
