FIELD: chemistry. ^ SUBSTANCE: apparatus contains a unit for crushing fluorescent lamps and a decontamination unit. The crushing unit is in form of a drum with revolving blades for crushing the glass of the lamps, a conveyor and a tray for feeding glass into the decontamination unit. The decontamination unit is in form of a mixer for a demercuration solution and the processing milling agent, which is mounted on a base with possibility of being rotated by a drive and tipping over in order to unload the processed product, a container for collecting the processed product which is mounted on a movable tray with a gutter for draining the spent solution, and a receiving tank from which spent solution can be pumped through a filter with a sulphonated carbon KU-2 filling and then taken for burning in a furnace to obtain mercury metal. The demercuration solution contains potassium permanganate KMnO4 - 0.0002525 g/l, hydrochloric acid HCl -0.000125 g/l and process water - 0.0375 g/l for one recycled fluorescent lamp. Said solution is at 28C. ^ EFFECT: high efficiency and energy-saving when processing fluorescent lamps and purifying gases. ^ 1 dwg |
