一、结构特点: 太阳能水压循环式沼气池是根据水压式三结合沼气池原理设计的,由发酵间、贮气室、进料口、水压间、反堵活动盖、导气管、搅拌器等部分组成(如图)。水压间设在池盖上,内涂黑漆为吸热层、池上用塑料薄膜封盖。这是以水压间兼作浅池式太阳能热水器,采光面积约三平方米。以水压进行自然循环,利用太阳能对沼气发酵液加热升温(可提高池温5—7℃),提高产气量。沼气池上部装有沼气吸液搅拌器,以杠杆式压水井头连接塑料管,伸入池内抽吸促使池液原料上下浮动,打破池内结壳层,同时还可用来进行大出料。搅拌器还配有贮液池,抽吸的
First, the structural features: Solar water cycle biogas digester is designed according to the principle of hydraulic three combined biogas digesters, and consists of fermentation chamber, gas storage chamber, feed port, water pressure, anti-blocking cover, air duct, And other components (Figure). Water pressure between the pool cover, black paint for the endothermic layer, the pool cover with plastic film. This is a combination of water pressure and shallow pool solar water heaters, lighting area of about three square meters. Water pressure for natural circulation, the use of solar energy heating biogas fermentation liquid (can increase the pool temperature 5-7 ℃), increase gas production. The upper part of the biogas digester is equipped with a biogas suction stirrer, which is connected with a plastic pipe by a lever-type pressure water well head. The aspiration into the sump causes the liquid raw material to float up and down, breaking the crust in the sump and also being used for large discharge. The blender is also equipped with a sump, aspirated
