Description

но зон. в систему, состо щую из расплавленного битума, радиоактивных отходов и воды, снизу вдуваетс  через специально выполненную форсуночную систему инертный газ, благодар  чему в адсорбционной зоне возникает пенна  фаза. Эта пенна  фаза так разрушаетс  ПОД воздействием температуры, что сухое вещество радиоактивных отходов заделываетс  равномерным и тонким слоем распределенным в битум, и вода испар етс . Испар ема  таким образом вода конденсируетс  в расположенном над абсорбционной зоной конденсаторе .but zones. A system of inert gas is blown into the system consisting of molten bitumen, radioactive waste and water, from the bottom through a specially designed nozzle system, due to which a foam phase occurs in the adsorption zone. This foam phase is so destroyed under the temperature effect that the dry matter of the radioactive waste is embedded in a uniform and thin layer distributed into the bitumen, and the water evaporates. Water thus evaporated is condensed in a condenser located above the absorption zone.

Если заделываютс  твердые радиоактивные отходы, не содержащие воду, то соответственно этому должны конструироватьс  щламосборник , адсорбционна  зона и подающее (питательное) устройство. Формирование пенной фазы из битума, радиоактивных отходов и вдуваемого снизу инертного газа «происходит , как описано выще.If solid radioactive waste that does not contain water is filled up, then the collection container, the adsorption zone and the feeding (feeding) device must be constructed accordingly. The formation of the foam phase from bitumen, radioactive waste and inert gas blown from below “occurs as described above.
