基于响应面法对一种连续型矩形微波反应器加热效果的模拟优化

摘要为了提高连续流微波反应器的物料温升以及加热均匀性，设计了一种具有特殊形状管道的连续流动矩形微波反应器，运用多物理场耦合计算的方式，探究了物料流速、馈口功率、馈口高度与管道高度对反应器的加热效果和加热均匀性的影响规律。研究结果表明：当管道与馈口平面相近时，物料有较高的温升，但加热均匀性较差；而当2者相距较远时，物料温升较小，但均匀性较好。通过运用响应面分析法对反应器结构进行优化：最高温升率可以达到24.28%；加热均匀性最佳的的管道高度为-38.88 mm，馈口高度为32.81 mm。

Abstract： A continuous flow rectangular microwave reactor with special shape pipe was designed for improving the material temperature rise and heating uniformity of continuous flow microwave reactor. The multi-physics simulation method was used to explore the influence of material flow rate, waveguide power, waveguide position and pipe height on heating effect and heating uniformity. The results show that the temperature rise of the material is higher when the pipe is close to the waveguide, but the heating uniformity is poor; When the distance between them is far, the temperature rise of the material is small, but the uniformity is good. The response surface methodology (RSM) method was used to optimize the structure of pipe and the maximum temperature rise rate was up to 24.28%, the waveguide height with the best heating uniformity is -38.88 mm, and the pipe height is 32.81 mm.
