| 摘 要： | 对流化床厌氧反应器的流化及反应特性进行研究,结果显示:床层实际初始流化流速umf为0.138～0.154cm/min,与理论计算值0.143 cm/min一致;在一定范围内,流速增大有利于反应量的提高,当流速为0.414 cm/min时,单位时间内的反应量达到最大,其值为4.66 mg/(L·min);适当提高流速有利...

| Abstract: | It is researched the fluidization and reaction characteristics of fluidized bed anaerobic reactor.Research result shows that actual initial fluidization flow is in the range of 0.138 ～ 0.154 cm /min,which is in good consistency with the calculated flow,0.143cm /min.Within a certain range of the flow,increasing flow rate is help to production load.When the flow rate is 0.414 cm /min,the maximum production load is 4.66 mg /(L.min).Improving the flow rate properly is help to gas production of each component,but influence of flow on the relative content of the gas produced is not significant,the content of CH4 is almost 7 times that of CO2.The bed expansion rate in cold model test is obviously lower than that in hot model test due to the gas produced.Within a certain range of the experiments,the bed expansion rate is raised with the increase in flow rate. |
