摘　　要：为探究固态储氢换热装置储放氢反应速率的影响因素,构建了一种固态储氢换热装置,数值模拟研究了各因素对固态储氢换热装置储放氢反应的影响,对比分析了同截面不同位置上的储放氢反应速率的差异性。结果表明,进行储氢反应时,供氢压力从3 MPa增加到5 MPa,储氢反应时间缩短16%;换热流体入口温度从550 K降低到450 K,储氢反应时间缩短57%;同工况同截面下,距换热流体管路越远的材料储氢反应速率越慢;进行放氢反应时,以F=0.2为限,压力从0.3 MPa提高到0.5 MPa时,放氢反应时间延长23%;以F=0.3为限,换热流体入口温度从550 K升至650 K时,放氢反应时间缩短41%;同工况同截面下,距换热流体管路越远的材料的放氢反应速率越慢。In order to explore the influencing factors of hydrogen storage and release reaction rate of solid hydrogen storage and heat exchange device,a solid hydrogen storage and heat exchange device was constructed.Numerical simulation studies were conducted on the effects of various factors on the hydrogen storage and release reactions of solid hydrogen storage and heat exchange devices,the differences in hydrogen storage and release reaction rates at different positions on the same cross-section were analyzed and compared.The results showed that when the hydrogen storage reaction was carried out,the hydrogen supply pressure increased from 3 MPa to 5 MPa,and the hydrogen storage reaction time was shortened by 16%.The inlet temperature of the heat exchange fluid was reduced from 550 K to 450 K,and the hydrogen storage reaction time was shortened by 57%.Under the same working condition and cross-section,the farther away from the heat exchange fluid pipelines,the slower the hydrogen storage reaction rate of the material;when conducting a hydrogen release reaction,the time required for hydrogen release reaction extended by 23%when the pressure was increased from 0.3 MPa to 0.5 MPa with the limit of F=0.2;the time required for hydrogen release reaction decreased by 41%when the inlet temperature of heat exchange fluid was increased from 550 K to 650 K with the limit of F=0.3.Under the same working condition and cross-section,the farther the material was from the heat exchange fluid pipelines,the slower the hydrogen release reaction rate was.
