Thermal Study on DBD Reactor With Intermediate Frequency Voltage
-
摘要: 通过实验监测DBD(dielectric barrier discharge)温度变化情况,探讨了温升所引起的热转移机理,得出DBD热变化表达式,并推导出相应的能量分配式及ΔTave计算式.实验结果表明:高频放电过程中,DBD反应器温度随电压升高和时间延长而上升,它们之间呈非线性关系;DBD反应器温度随频率提高和时间延长而升高,随气体速度的提高而降低,温度变化与时间、频率及气体速度均呈现出线性关系.Abstract: Temperature in Dielectric barrier discharge(DBD) reactor increased obviously under high frequency alternating current(AC).The change trends of DBD temperature were tested.Heat transfer mechanism was established,and formula of energy distribution and ΔTave were educed.The experimental results show that DBD temperature increased with voltage and time increasing in high frequency discharge and their relationships were non-linear.DBD temperature increased with frequency and time increasing,and with gas influent rate decreasing.All of these factors and DBD temperature presented linearity.At the end,there was a better foreground for application to industry or family of low frequency AC in the future.
