Related Articles

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.
