为了提高农村家用沼气池的池容产气率,改变沼气池出料难状况和使所产沼气的压力更加符合各种燃烧器的额定压力,我们设计了“双层干湿交替发酵沼气池”。经过安徽省阜阳地区、四川省重庆市等地的验证试验,效果较好。“双层干湿交替发酵沼气池”的结构如图所示。它分上下两个发酵室。上发酵室类似半塑式沼气池,配料浓度一般控制在20%(TS)左右,是干发酵部分。下发酵
In order to improve the gas production rate of domestic household biogas digesters, change the difficult situation of digester discharge and make the pressure of produced biogas more in line with the rated pressure of all kinds of burners, we designed “double-layer wet and dry alternating fermentation digester” . After the Fuyang area in Anhui Province, Chongqing Municipality in Sichuan Province and other places of the validation test, the effect is better. The structure of double-layer wet-dry fermentation digester is shown in the figure. It points up and down two fermentation room. On the fermentation chamber similar to the semi-plastic biogas digester, the ingredients concentration is generally controlled at about 20% (TS), is part of the dry fermentation. Fermented
