Filed: 1983-08-30
Abstract: PURPOSE:To enable operation stable over a long period of time by excluding the clogging of a nozzle or the accumulation of a lumpy substance, in a spray nozzle used in a fluidized layer reaction apparatus, by attaching an induction cylinder to the leading end of the nozzle. CONSTITUTION:In a fluidized layer reaction apparatus for obtaining a solid substance in a fluidized layer state by the treatment (chemical reaction or drying) of a liquid (including a solution and a slurry form) or gaseous substance, an induction cylinder 6 is attached to the leading end of a nozzle 1 for spraying and supplying a substance to be treated. For example, when uranyl nitrate to be thermally decomposed is sprayed from the nozzle 1 as shown by the numeral 3, a lumpy substance 2 is adhered to the leading end 6a of the cylinder 6 and grown. In this case, because the contact (adhesion) area of the lumpy substance is small and adhesion force is weak, the lumpy substance 2 is easily detached. In addition, because the lumpy substance 2 receives the force of the sprayed body 3 expanded to a certain degree on the way of the growth thereof, it is simply detached. By this structure, because the clogging of the nozzle 1 is not generated and the formed lumpy substance 2 becomes small, a substance to be treated is easily fluidized and discharged by overflow.
