摘　　要：基于煤矿乏风热逆流氧化试验,建立该试验装置的关键部件—蜂窝陶瓷蓄热体的传热模型,对工作状态下陶瓷蓄热体的温度场进行了仿真,分析了蓄热体的孔隙率、孔型和操作参数对蓄热体温度的影响规律。结果表明:随着孔隙率的增大,蓄热体蓄热时间变短,蓄热速率增大;在材质和孔隙率一定的情况下,六方孔型蓄热体蓄热速率要大于四方孔型蓄热体;随着气体入口流速的增加,蓄热体的蓄热速率增大,蓄热时间降低。Ceramic honeycomb regenerator as a critical component about the coalmine ventilation air methane thermal oxidation was proposed for a self-developed thermal reverse-flow reactor. In this paper, a heat transfer model was established to obtain the distribution of temperature under operating parameters of the oxidation bed, structural parameters of honeycomb ceramic. The results show that the regenerator heat storage time is shorter with the increase of porosity. The hexagonal regenerator heat storage rate is faster than the square opening one. With the increase of ventilation air methane superficial velocity, heat storage rate of regenerator increases.
