| 摘 要： | 本试验拟采用自制沼气工程保温恒温系统装置,研究了发酵罐内底部加热、内侧壁加热和底部内侧壁组合加热3种加热方式,高温发酵、中温发酵2种发酵工艺等6种状态下,发酵料液温度场分布规律和温度场随时间变化的波动.结果表明:发酵罐内任1种加热方式的发酵料液温度场稳定性、加热的热效率均优于发酵罐外侧壁加热方式.发酵罐内底部加热是较佳的加热方式,其发酵料液温度场分布最稳定,温度场随时间变化的波动最小.

| Abstract: | Under 6 states,namely mesophilic and thermophilic digestion with three types of heating mode,including heating from the bottom of digester,heating from the inner wall of digester,and combination of heating from the bottom and from the inner wall of digester,the temperature distribution of mixed liquid in digester and temperature fluctuation with time were investigated using self-made heating devices of digester.Results showed that both of the temperature stability of mixed liquid in digester and heating eff... |
