微波裂解腔体波导管馈口分布对废旧橡胶裂解的影响

Influence of Distribution of Waveguide Feed Ports of Microwave Pyrolysis Cavity on Waste Rubber’s Pyrolysis

在废旧橡胶的微波裂解腔体上设置4个波源和相应波导管,使用HFSS软件建立微波裂解模型,对裂解腔体上波导管馈口的分布方式和间距进行电场分布和微波能损耗分析。结果发现,微波裂解腔体上相邻波导管馈口中心间距为150 mm且波导管馈口呈正交分布时,相邻波源之间相互干涉最小,废旧橡胶裂解的微波能有效利用率最高,微波能反射损耗最低。本仿真结果可为废旧橡胶微波裂解腔体设计提供依据。

Four wave sources and corresponding waveguides were set up on the microwave pyrolysis cavity for waste rubber.The microwave pyrolysis model was established by using HFSS software.The electric field distribution and microwave energy loss of the distribution and spaces of the waveguide feed ports on the pyrolysis cavity were analyzed.The results showed that,when the center distance between adjacent waveguide feed ports was 150 mm and waveguide feed ports were orthogonally distributed,the interference between adjacent wave sources was the smallest,the microwave energy efficiency of the waste rubber pyrolysis was the highest,and the microwave energy reflection loss was the lowest.The simulation results could provide a basis for the design of the microwave pyrolysis cavity for waste rubber.
