摘要
单体厌氧消化器和串联式厌氧消化器是两种常见的沼气工程形式。把厌氧消化系统作为一个液压系统考虑,建立两个系统的数学模型,运用Matlab/Simulink软件分别对系统的液位变化进行仿真,结果反应了两种形式的厌氧消化器内部液位动态变化规律。结果表明,单体厌氧消化器的回复性和稳定性较串联式好,建议对于中小型沼气工程或管理比较粗放的沼气工程,采用单体或并联式厌氧消化器形式。
Single anaerobic digester and digesters in series connection are the common forms of biogas plant.Considering the anaerobic digestion system as a hydraulic system and establishing their respective mathematical models,the simulation calculation was done with matlab/simulink software,the results of which could reflect the regulation of fluid performance in anaerobic digester.The result showed that recovery and stability of single anaerobic digester is better than that in series.It is advised that single or parallel anaerobic digester is more suitable to small and medium biogas plants.
