| 摘 要： | 秸秆沼气工程中厌氧、贮气CSTR工艺研究表明,将沼气贮气柜直接安装在厌氧发酵反应罐顶部,减少贮气柜工程占地的同时减少厌氧反应罐建造成本。贮气柜采用具有膨胀、收缩功能的半球体状贮气内膜和贮气外膜,贮气内膜与罐体液面构成密闭半球形贮气柜,贮气内膜和贮气外膜之间充入空气压力为2500Pa,厌氧罐底部安装有热循环加热管以保证冬季对厌氧罐进行加热。厌氧罐反应温度为中温发酵(36℃)。潜水式搅拌机安装在反应液面处,该搅拌机的叶片一部分露出反应物料的液面,将漂浮在反应液表面的浮渣破碎,同时可将反应液上下搅拌,使得菌种较均匀分布于反应液中,以利于沼气的生产。

| Abstract: | Research on anaerobic and gas collection of CSTR system in straw biogas was studied.The results showed that installing the biogas collector at the top of the anaerobic reactor could save the space of the construction site and save the construction cost.Biogas collector composed of two parts:outside membrane and inside membrane,both the outside membrane and the inside membrane were hemispherical and could be expanded and shrunk according to the pressure of the inner biogas.Air pressure between the outside me... |
