INSTALLATION FOR URANIUM DIOXIDE POWDER METHOD OF pyro-hydrolysis of uranium hexafluoride

摘要

The proposed group of useful models relates to the field of metallurgy, in particular to devices for obtaining uranium dioxide powder by pyrohydrolysis. The technical result of the utility model is to eliminate the condensation of water vapor in the discharge chamber of the furnace and its wet powder clogging while improving the reaction efficiency dovosstanovleniya uranilftorida. In a plant for producing uranium dioxide powder from uranium hexafluoride, comprising at least one heated reaction chamber with a nozzle for feeding into it the reaction components pyrohydrolysis uranium hexafluoride, unloading and transport means of the obtained powder of uranium dioxide and furnace dovosstanovleniya unreacted uranilftorida having a discharge chamber 28 with pipes 29 and 30 for supplying hydrogen and steam oven according to the proposal of the nozzle end portion 30 for supplying water vapor is located in the retort 2 7 the furnace and provided with a closed end and with the holes in the side wall. Furthermore, another pipe discharge chamber is arranged to supply hydrogen in admixture with nitrogen. Additionally, to reduce overgrowing nozzle solids nozzle for supplying the reaction components pyrohydrolysis reaction of uranium hexafluoride formed three-channel, the central channel of which is designed to feed uranium hexafluoride, an intermediate coaxial channel - for supplying nitrogen and an outer coaxial channel - for supplying of steam and hydrogen.
