Qufu fabric biogas digesters are based on the "round, small, shallow" cylindrical biogas digesters, and have been screened to design a new type of biogas digester with advanced fermentation technology and pool structure.
I. Features 1. The structure of the pool is reasonable. The raw material enters the pool and is controlled semi-controlled or fully controlled by the manifold. The capacity of the tank capacity is fully utilized. The gas production rate of the tank capacity is high.
2, low cost, own energy consumption; simple and convenient operation, easy to promote.
3, using continuous fermentation process, fermentation conditions and stability.
4. The bottom of the tank is inclined from the feed inlet to the discharge outlet. The lowest point of the bottom of the tank is at the bottom of the discharge outlet. Under the action of the inclined bottom, a flow thrust is formed to realize the self-flow of the main fermentation tank.
5, can use external force linkage stirring device or internal pressure stirring to prevent liquid crust.
Second, the technical specifications Qu stream cloth biogas digester using continuous fermentation process, the main fermentation tank volume of 6 meters 3, the raw material concentration requirements of about 5%, the daily feed amount of about 100 kg. Related supporting technologies include:
1, the meandering cloth digester overall steel mold.
2. Meandering device for methane-filled shells.
3, the meandering material biogas digester is connected with the stirring device.
4. ZF-300 miniature biogas generator.
The pool capacity is 0.9 m3/m3·day. The raw gas production rate is 0.497 m3/kg solids, and the annual gas production is 1000-1600 m3.
Third, the scope of application, conditions The pool is suitable for economic conditions, rich in raw materials (daily feed amount of 100 kg), energy-intensive aquaculture developed areas require family members have a certain degree of cultural and technological knowledge, especially suitable for science The specialized breeding households, science and technology households that are under management may require the construction of high-grade biogas digesters.
