device and method for removing mercury from mercury contaminated materials

摘要

A device (10) for removing mercury from mercury-contaminated material, comprising a chamber (11) having an inlet (13) for mercury- contaminated material, and a sieve (12) arranged inside the chamber (11) for separating a larger material fraction of the mercury-contaminated material from a smaller material fraction thereof, wherein the chamber (11) is provided with a first outlet (14) for the larger material fraction and a second outlet (15) for the smaller material fraction. The device (10) comprises at least one heating element (18) to evaporate mercury on at least the larger material fraction inside the chamber (11), so that mercury on the larger material fraction is removed by heating. The chamber (11) is provided with a third outlet (19) for an outlet flow of vaporized mercury.
