Title: Treatment of discarded fluorescent lamp and its device
Inventor: TOKUDA SHINGO
IPC: B01D53/64
Filed: 1984-12-25
Abstract: PURPOSE:To improve the working atmosphere and to prevent the generation of a pollution-related problem by removing mercury almost completely wherein it is contained in the vapor generating in a period of crushing a fluorescent lamp. CONSTITUTION:A discarded fluorescent lamp is introduced and crushed in a vessel 1 provided with a glass crusher 3 and a gas contg. the vapor generating from the crushed pieces is sucked and discharged while keeping the inside of the vessel 1 in the reduced pressure by actuating a suction machine 12. Mercury particles and the powder of fluorescent paint or the like contained in the above-mentioned vapor are removed with an air filter 7 provided to a front stage of an exhaust flow path and furthermore the remaining mercury is removed with a packed layer 10 of solid chelate agent which is provided to the rear stage of the exhaust flow path. By this method, the crushing treatment of the fluorescent lamp discarded in large quantities can be efficiently performed with a simple device. Since mercury vapor is not dissipated from the fluorescent lamp treated in such a way even while conveying it, it can be safely conveyed to an incinerating treatment installation of a mining station or the like and is extremely useful in the environmental pollution control measure.
