褐煤因其含水率太高无法合理利用。介绍了一种用于褐煤脱水的低温微波装置。该装置采用新型微波加热技术,与传统方法相比,具有高效、安全和无污染的优点。详细介绍了该装置的组成、主要指标。采用多模谐振腔的设计提高了加热均匀性和加热效率,特有的微波漏能抑制器和网孔设计使微波泄漏功率很小。应用微波理论和仿真进行了较深入的分析,仿真也验证了理论分析结果。最后,实验数据表明,该装置的处理能力和加热均匀性均达到预期,性能良好。其研究成果可推广于产业化应用。
Brown coal can not be used reasonably because its moisture content is too high. A low temperature microwave device for lignite dehydration is introduced. The device uses a new microwave heating technology, compared with the traditional method, with high efficiency, safety and pollution-free advantages. Details the composition of the device, the main indicators. The design of multi-mode resonant cavity improves the heating uniformity and heating efficiency. The unique microwave leakage suppressor and mesh design make the microwave leakage power very small. The application of microwave theory and simulation conducted a more in-depth analysis, the simulation also verified the theoretical analysis. Finally, the experimental data show that the device processing power and heating uniformity are expected, good performance. Its research results can be extended to industrial applications.
