Problems solved by technology

[0010] Thanks to U 3 o 8 Powder is a nuclear material, which involves radiation protection and nuclear proliferation issues, and the sol-gel process has very strict requirements for dissolution. This dissolution process can still be produced in small batches under the condition of using a simple beaker and manual operation. It is difficult to realize mass production of equipment

Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] like figure 1 As shown, the dissolving device of the embodiment of the present invention includes: a sealed reaction tank 1, a feeder 9 connected to the reaction tank 2, a liquid inlet pipeline, a circulation stirring system, an air flow stirring device and an exhaust pipe.

[0033] Among them, the reaction tank 1 is made of stainless steel and is cylindrical, which is used to store reactants and provide a reaction place. The diameter of the cylinder is calculated according to the critical safety of the material, and it meets the critical safety under the maximum production capacity. Discharge pipe 7 for discharge. A heating jacket 2 is installed on the outer wall...

Abstract

The invention relates to the technical field of reactant dissolving equipment, in particular to a dissolving system, which comprises a reaction tank, a feeder connected with the reaction tank, a liquid inlet pipeline, a circulation stirring system and an air flow stirring device. The reaction tank is used for storing reactant and providing reaction places, and a discharge pipe for discharging materials is positioned at the bottom of the reaction tank. The circulation stirring device and the air flow stirring device are used for quickening dissolving speed of the reactant in the reaction tank.The feeder and the liquid inlet pipeline are used for adding the reactant. The dissolving system is simple in structure, convenient to operate, large in production and capable of meeting requirementsof large batch production, effectively enabling U3O8 powder to be dissolved quickly and completely and achieving lack acid dissolving to obtain lack acid uranium nitrate solution.

Description

technical field [0001] The invention relates to the technical field of reactant dissolution equipment, in particular to a dissolution system. Background technique [0002] At present, the sol-gel method is usually used to prepare ceramic microspheres, and this process is applied to the preparation of uranium dioxide cores for spherical fuel elements of high-temperature gas-cooled reactors. The uranium dioxide fuel core requires a diameter of about 500 microns, and the required size is extremely strict. Among them, the preparation of uranium dioxide core by sol-gel method mainly has the following steps: [0003] (1) Dissolved, three uranium octaoxide (U 3 o 8 ) powder is dissolved in nitric acid, and configured into a uranyl nitrate solution with a certain concentration of uranium atoms; [0004] (2) boil the glue, add urea in a certain metering ratio in the uranyl nitrate solution, evaporate and concentrate at a certain temperature for a certain period of time, add a thi...
