现浇混凝土沼气池,只要按照国家标准图纸施工,遵守施工操作规程,一般使用寿命可达30年之久,甚至更长一些时间。但是,如果缺少夹层水密封这一项新工艺便会影响沼气池产气、用气,甚至使沼气池报废。通常有些沼气池产气不够理想,实际上是用气不够理想,气箱没有气或气不足。查找原因,其它一切正常,只是没有夹层水密封,把土挖开后,洗干净气箱部分混凝土壳体,加做了石灰砂浆夹层,效果是很理想的,产的沼气用不完,有的可供两户使用(在夏天、气温高时),所以,夹层水密封是建池中重要工艺。现在有的没有做夹层水密封,蓄水圈壁没有留引水孔,可以按新的蓄水圈方法处理,即在蓄水圈壁不留引水孔,而在蓄水圈壁外夹层留有1—2孔,
In-situ concrete methane tanks, as long as the construction in accordance with national standards, follow construction procedures, the general life of up to 30 years, or even longer. However, if a new process of sandwich water seal is missing, it will affect the gas production and gas use of the biogas tanks, and even make the biogas tanks obsolete. In general, some biogas digesters produce less than ideal gas. In fact, the use of gas is not ideal. There is no gas or gas in the gas box. Find the reason, everything else is normal, but there is no water seal sandwich, after digging the soil, clean the air box part of the concrete shell, add a lime mortar sandwich, the effect is very good, the production of biogas can not be used, and some It can be used by two households (in the summer when the temperature is high), so the sandwich water seal is an important process in building the pool. At present, some do not have a sandwich water seal, and there is no water intake hole in the wall of the water retaining ring. It can be handled in accordance with the new water retaining ring method. That is, no water intake hole is left in the water retaining ring wall, and there is a gap in the outer wall of the water retaining ring. - 2 holes,
