目前,农村推广的沼气池活动盖直径较小.对于以秸秆为主的发酵原料来说,大出料难度较大.为此,我们建成一个大口径活动盖分离浮罩式沼气池,介绍如下:一、池型结构与设计原理沼气池由发酵间、浮罩贮气间和贮粪池组成,如图所示.大活动盖设于池子的顶部,周围砌好养水圈.在养水圈内加满水后,发酵间被密封.这时,产生的沼气通过输气管道输送到浮罩内.发酵间内的沼 At present, the popularization of biogas digesters in rural areas covers a relatively small diameter, and it is more difficult for the fermented raw materials mainly composed of straw to produce larger digesters. Therefore, we have built a large- : First, the pool structure and design principles Biogas digester by the fermentation room, floating hood gas storage and septic tanks, as shown in the figure. Large activities covered in the top of the pool, built around the water ring. The circle filled with water, the fermentation was sealed. At this time, the resulting biogas through the gas pipeline to the floating hood. Fermentation inside the marsh
