OSCILLATORY STIRRING DEVICE OF ANNULAR APPARATUS Russian patent published in 2012 - IPC G21F9/34 

FIELD: chemistry.

SUBSTANCE: oscillatory stirring device has a nozzle assembly, a distribution cavity, a pulsation chamber with a pulse conductor and an air distributor. The pulsation chamber consists of two partition walls in the annular space of the apparatus, in the lower part of said walls of which there are holes linked to the distribution cavities entering the annular space of the apparatus. The holes in the partition walls are connected to distribution cavities which are in form of U-shaped deflectors whose bases lie adjacent to the bottom of the apparatus with a gap or to distribution cavities in form of radial tubes with nozzles directed an angle to the bottom of the apparatus. The lower connecting pipe of the pulse conductor in the pulsation chamber can have plugged end and holes on the sidewalls.

EFFECT: high intensity of stirring, avoiding formation of residue at the bottom of the annular apparatus and reduced escape of radioactive aerosols with waste compressed air.
