摘　　要：针对微波反应器加热均匀性的问题设计了一种带夹层的釜式微波反应器,运用多物理场仿真的方法,探究波导位置和夹层厚度对其加热效率和加热均匀性的影响规律。结果表明:波导位置在物料液面之下普遍可以取得较高的加热效率,但加热均匀性较差;夹层可以有效改善反应器的加热均匀性,并在部分情况下提高加热效率。通过运用响应面分析法对反应器结构进行优化:最高加热效率可以达到99.19%;加热均匀性最适宜的波导高度为389.74 mm,夹层厚度为30.09 mm。A microwave oven with interlayer was designed for the problem of heating heterogeneity in microwave reactor.The multi-physics simulation method was used to explore the influence of waveguide position and interlayer thickness on heating efficiency and heating uniformity.The results show that the waveguide position can generally achieve higher heating efficiency under the liquid level of the material,but the heating uniformity is poor;and the interlayer can effectively improve the heating uniformity of the reactor and,in some cases,increase the heating efficiency.The response surface methodology(RSM)was used and the maximum heating efficiency of the optimized up to 99.19%,the waveguide height with the best heating uniformity is 389.74 mm,and the interlayer thickness is 30.09 mm.
