DEVICE AND METHOD FOR DISPOSAL OF MERCURY-CONTAINING WASTES Russian patent published in 2017 - IPC B09B3/00 

FIELD: ecology.

SUBSTANCE: invention can be used to neutralise solid waste, including mercury-containing wastes generated by production activities, including mercury thermometers, energy-saving lamps, fluorescent lamps and other wastes containing mercury. The device for neutralizing mercury-containing wastes contains a mixing drum for mixing mercury-containing waste, a pulverizing medium and a liquid that contains sulfur, to break the mercury-containing waste and the reaction of binding mercury-containing mercury metal waste with sulfur to mercury sulphides, a loading tray that is sealed, A vessel containing a liquid containing sulfur through which gases are passed from the mixing drum through the liquid contained in the vessel st for binding reaction with sulfur vapour mercury in mercury sulfides. A method for neutralizing mercury-containing waste includes loading a grinding medium to break a mercury-containing waste into a mixing drum that is mounted on a mobile platform, sealing the loading tray tightly, rotating the mixing drum, allowing the mercury-containing mercury-containing waste to react with sulfur to form mercury sulphides, pumping gases from the mixing drum, The passage of gases through a vessel containing a liquid containing sulfur to bind mercury vapour to sulfur, returning the gases in the mixture Round drum.

EFFECT: reducing the negative impact on the environment, increasing the level of neutralisation of mercury-containing waste.
