Analysis and optimization of temperature field uniformity of proton exchange furnace

  • 摘要:

    针对质子交换炉的温度场均匀性问题,结合质子交换炉的结构特点,基于FLUENT用户自定义函数(UDF)开发了质子交换炉炉温控制算法,并在此基础上提出了多种加热控温方案;利用FLUENT软件对不同方案下的质子交换炉温度场进行仿真,分析不同控温方式下炉内温度场均匀性与传感器位置布置、加热丝布置高度的关系,找到最佳方案。结果表明:采用三段控温、3个传感器位置分别布置在3段加热丝中间、加热丝布置高度4倍于均匀温区长度时炉内温度场均匀性最好,均匀温区内最大偏差为0.03℃;对于既定结构的立式炉体,增加加热丝布置高度、优化设计传感器布置方案和炉体控温方式可以提高温度场均匀性。该方法为同类电加热炉温度场均匀性的优化设计提供了思路。
