某放射性废金属熔炼炉接受式排风罩优化研究

Abstract

Abstract: Purpose: In order to effectively collect radioactive aerosols generated during the re-smelting process of scrap metal in nuclear facilities, and to protect the health of workers, we conducted a research on the optimization of the receiving exhaust hood. Method: A certain radioactive scrap metal smelting furnace was selected as the research object. We established a model, divided the grid, and finally used the Fluent numerical simulation method to simulate the influence of factors such as different heights, different hood sizes, and interference winds on the exhaust hood. Results: The smelting furnace mouth diameter is 0.5 m, there is a cross-wind of 0.3 m/s, and the height of the exhaust hood is 1.5 m. The optimized exhaust hood is a circular hood with a diameter of D=1.4 m, which can effectively eliminate the radioactive aerosol produced by smelting furnace. Conclusion: Compared with the theoretical calculation design, the exhaust hood optimized by the CFD numerical simulation method has reduced the diameter of the exhaust hood by 0.84 m and the air volume by 0.616 m³/s, which saves space and energy. It can provide reference for the design of smelting furnace exhaust hood.
