INSTALLATION FOR EVAPORATION OF THE URANIUM HEXAFLUORIDE Russian patent published in 2007 - IPC C01G43/06 

FIELD: atomic industry; chemical industry; devices for evaporation of the uranium hexafluoride from the solid phase into the gaseous phase.

SUBSTANCE: the invention is pertaining to the equipment for evaporation of the uranium hexafluoride from the solid phase into the gaseous phase, from the containers in the technological cascade for separation of the uranium isotopes, and may be used in the atomic industry. Installation works as follows. At the removed cover (2) and the tilt-back supports (20) the container (I) is installed by the crane into the body (1) on the supports (19) orienting the container on the guides (21). The supports (20) set into the working position and set on them the container (II). To the valves of the containers I and II connect the technological pipe ducts (12) and (13) connecting the containers with the technological cascade on separation of the uranium isotopes. The places of the joints check for leakage and open the valves of the containers. On the body (1) by crane set the cover (2). Switch on the electrical engine (8) of the blower (5) and the heater (3). The hot air heated by the heater (3) through the diffuser (9) is inhaled by the blower (5) and pumped into the cavity "A", whence through the air ducts is fed into the cavities "B" and "C". At the outlet of the air ducts formed by the removable partitions the hot air is routed by the deflectors (22) into the lower part of the container (I), and from the air ducts formed by the pockets of the lateral walls of the body, it is routed to the lower part of the container (II) and into the upper part of the container (I). The hot air is moving along the walls of the containers to the inlet of the blower (5) through the heater (3). This way the heating of the containers and the subsequent evaporation of the uranium hexafluoride from them into the technological cascade on uranium isotope separation is exercised. After termination of the process of evaporation of the uranium hexafluoride from the containers the heater (3) and the blower (5) are switched off. Open the small door (23) in the cover (2) and cool the containers, pumping the cold air through the small door (23) into the ventilation system. After cooling of the containers lift the cover (2) off, open the small door (11) and shut the valves of the containers, disconnect the pipe ducts (12) and (13) and pull the containers out. The technical result of the invention is the increased efficiency of the installation without occupation of the larger working areas.

EFFECT: the invention ensures the increased efficiency of the installation without occupation of the larger working areas.
