Abstract: An apparatus and method are provided for mixing gas and liquid. An impeller is rotatably mounted inside a draft tube. Inlet baffles are mounted adjacent the inlet end of the draft tube in close proximity to the impeller. In addition, outlet baffles are mounted adjacent the outlet end of the draft tube in close proximity to the impeller. Rotation of the impeller draws liquid down through the draft tube and creates vortices which serve to entrain gas into the liquid. The provision of inlet and outlet baffles directly adjacent the rotating impeller produces high gas entrainment and shear rates and improves gas transfer efficiency. The gas-liquid vortex mixer is particularly suitable for treating industrial and municipal waste water, as well as various other liquids. Gases such as air, oxygen, hydrogen, and the like are efficiently dissolved in such liquids during operation of the gas-liquid vortex mixer.

Abstract: A process for preparing uranium tetrafluoride by reacting a uranous solution with a hydrofluoric acid solution in a fluorination precipitation tank is provided. A cylindrical inner tube having upper and lower ends opened is disposed in the tank in the longitudinal direction thereof. An agitator is arranged within the inner tube to generate a descending or ascending stream inside the inner tube and a ascending or descending stream outside the inner tube, thereby producing a circulation of reaction liquor in the tank. The uranous solution and the hydrofluoric acid solution are introduced into the tank from the upper part thereof and the produced uranium tetrafluoride crystals are withdrawn from the lower part of the tank together with a part of the reaction mother liquor. The amount of the hydrofluoric acid solution added to the uranous solution is adjusted so that the fluorine concentration in the reaction mother liquor in the tank is maintained at 2 to 4 g/l.
