Structure of furnace body in mercury separation and recovery equipment from mercury-containing materials

摘要

PPROBLEM TO BE SOLVED: To provide a structure of a furnace body in an apparatus for separation and recovery of mercury from a mercury-containing material by an efficient dry process in which a wide heating and contact area can be secured using a small space and uniform agitation can be attained and the size of a heat source can be reduced. PSOLUTION: The inside of a cylindrical furnace body 1 which has a mercury-containing material feeding hole 2 and a mercury vapor discharge hole 5 at the top and a discharge hole 17 for discharging a fluorescent agent etc. at the bottom is erected. The inside of the furnace body 1 is divided into a plurality of steps in a vertical direction. Each partition plate 10 to be a bottom of each divided space is provided with a dropping hole 11, and the respective dropping holes 11 of the partition plates 10 in a vertical positional relationship are provided in such a way that they are in the positions dissimilar to each other on the respective plate surfaces. Further, rotary vanes 14 rubbing on the surface of the circular partition plate, regarding the center of the surface of the partition plate as a rotation axis 15, are provided.
