SETUP FOR MERCURY EXTRACTION FROM LUMINESCENT LAMPS Russian patent published in 2013 - IPC C22B43/00 

FIELD: metallurgy.

SUBSTANCE: setup includes a lamp crushing unit, a container with demercurisation solution, a decontamination unit made in the form of a mixer for waste decontamination, which is fixed on the base with possibility of being rotated by means of an actuator and overturned for unloading of derivative product, a loading device with a movable tray, a derivative product collecting tank made in the form of a container installed on the tray with a chute for drainage of waste solution to the receiving tank and pumping of the solution by means of a pump through a filter with sulfonated carbon backfill of KU-2 type, and a furnace for combustion of backfill with sulfonated carbon and obtaining metallic mercury. The lamp crushing unit is made in the form of a continuous-action setup for obtaining fine powder from broken glass, which contains a receiving bunker, a jaw crusher for primary crushing, a screw conveyor for product supply to an elevator, a planetary mill made so that crushed product can be removed from it with an air flow, pipelines for transportation of crushed product to separator, in which the air flow is swirled with inclined blades with possibility of separation of material as to fineness degree by means of appearing centrifugal force, return of coarse material to the mill and transportation of fine product to the cyclone for collection of considerable part of ready product and its supply through a sluice valve via the pipeline to the receiving capacity.

EFFECT: improving efficiency and energy and resource saving of scrap processing and gas cleaning.
