METHOD OF UTILIZATION OF MERCURY-CONTAINING DEVICES AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2005 - IPC

FIELD: utilization of mercury-containing devices; processing rejected luminescent lamps and mercury-containing devices and devices whose service life has expired.

SUBSTANCE: plant for utilization of mercury-containing devices includes working bath, unit for breaking and treating the mercury-containing devices with liquid medium which is made in form of container with breaking devices and devices for supply of liquid medium, vibrator, working solution reservoir connected with breaking device by means of drainage pipe line laid in lowest point of working bath; plant is also provided with pipe lines equipped with fittings and pump for transfer of liquids; it is also provided with water reservoir which is connected with breaking device by means of drainage pipe line laid at definite height above bottom of working bath; working bath, water reservoir and working solution reservoir are combined in system which makes it possible to fill working bath in turn with water or with working solution by means of one pump; breaking device is made in form of cross-piece with knives secured on it. Proposed method of utilization of mercury-containing devices includes grinding of such devices under layer of water at continuous washing of luminescent substance, forming the suspension and settling mercury in form of finely-dispersed particles on bath bottom, after which mercury is subjected to neutralization with the aid of said plant. Breaking the mercury-containing devices and washing-off the luminescent substance will be performed by vibration; neutralization is accompanied by forming of insoluble calomel.

EFFECT: possibility of performing chemical demercuration at temperature close to surrounding temperature.
