| 中文摘要: |
| 针对废橡胶微波裂解出现的裂解速率下降、能耗上升问题,基于电磁仿真软件HFSS,在2.45GHZ工作频率下,对密封隔板表面附着不同厚度炭黑时的微波能传输进行了探究。认为,炭黑在密封隔板表面的附着会造成微波能的损耗,其附着厚度越大,微波反射率越高,能量传输率越低,导致了废橡胶裂解速率的下降和能耗的上升。通过改进波导结构形式,增加氮气吹扫隔离功能,可以解决炭黑的附着问题。 |
| 英文摘要: |
| For the problem of pyrolysis rate decline and energy loss increase when waste rubber pyrolyses in microwave body, this paper uses high frequency simulator software (HFSS) based on the finite element method at the frequent of 2.45GHZ,simulates and studies the microwave energy transmission when the corbon black adheres to the seal clapboard with different thickness. The result shows that the carbon black adhering to the seal clapboard brings about the energy loss rising. The more carbon black adhering, the more microwave refection, and the lower the energy transmission rate. At the same time, the pyrolysis rate is falling down, and the energy loss is rising. Improving the form of the waveguide and adding nitrogen puffing isolation function can make the carbon black adhering improved significantly. |
