FIELD: machine building.
SUBSTANCE: device comprises a unit to collect volcanic gas, a gas flue, a set of adsorbers, a system for adsorber washing and a set of electric filters, the device is equipped by a vertical aerodynamic tunnel from durable heat-resistant and acid resistant polymer film reinforced by polymer hoops which is attached to a balloon by automatic tension devices, the adsorbers and electric filters are mounted in the tunnel, it also comprises a wind mill, with its wind wheel being set in the above aerodynamic tunnel and providing for the air draft sufficient to drive the volcanic gas through adsorbers and to rotate the wind wheel in constant air flow due to the difference of the atmospheric pressure and the temperature gradient at the ends of the aerodynamic tunnel, a volcanic gas cooling unit made as a water cooling system for the gas comprising nozzles and membrane and mounted in the gas flue, a tank to collect lean rhenium solution and an ion-exchange column. The volcanic gas collection unit is made as a dome for gas collection which comprises extension-type branch pipes and a safety valve, is connected to the aerodynamic tunnel by the gas flue, made from durable heat-resistant polymer film and suspended under the balloon by ropes.
EFFECT: provision for selective separation of rhenium and production of rare metal concentrate.
