Puxin family size biogas system

1. Introduction of Puxin family size biogas plant
Puxin family size biogas system is composed of a 6 or *0 m3 Puxin family size biogas plant, pipe routes, and gas purify devices and gas appliances or small power biogas generator. Puxin family size biogas system is mainly applied to farmhouse or domestic house to treat livestock waste, straw, human sewage and food waste.

 (1) The structure：
Puxin family size biogas plant is composed of a concrete digester and a glass fibre reinforced plastic gas-holder. The digester is 6 or *0 m3 of capacity. The gas-holder is 1.6 m of diameter, 0.6 m of height and 1 m3 of capacity. 
 
（2）The features ：
 Easy and quick to be built
 Highly industrialized
 Solid organic material (straw and grass etc.) can be used
 Easy to maintain
 Durable
 Excellent safety feature
 Low cost
1）Easy and quick to be built：
 Any working mason through one days study is able to build Puxin family size biogas plant with **0% success rate.
 A Puxin family size biogas plant can be built within *8 hours.
Contrast of the technical requirements for the builders
Items Traditional fixed dome biogas plant Puxin biogas plant
Airtight craft Highly required Not required
Ability to understand blueprints Highly required（build by hand depending the blueprints） Not required (cast by mould)
Ability to build the arch Highly required (build by hand) Not required (cast by mould)
To judge and deal with gas leaking Highly required  Lowly required
To judge and deal with water leaking Highly required Required
Training period About 3 month About one week
Period to become a proficient builder 1－2 years About one month
Requirement of the people to be trained Medium educated, strong ability to master skills Not Educated, medium ability to master skills
Success rate Not **0ï¼… guaranteed **0ï¼… guaranteed
2）Highly industrialized：
 Fit for cosmically and fleetly spread: The steel mould and the gas-holder can be mass-produced in factory. So, the biogas plant can be cosmically and fleetly built.
 Quality of the biogas plant is highly guaranteed. Every digester duplicated by the steel mould can fit every gas holder duplicated by mold.  
3）Solid organic material (straw and grass etc.) can be used
 Traditional  fixed dome biogas plant Puxin biogas plant
Fluidities (like animal wastes) Allowed Allowed
Solids (like straw and grass) Not allowed
(because of the difficulty to replace solid fermentation material ) Allowed
 (convenient to replace solid fermentation material)
4）Easy to maintain
Items The traditional fixed dome  hydraulic biogas plant The Puxin Biogas plant
To mend the gas leak of gas-holder   Dangerous and difficult
The job is done inside the biogas digester; there is a possibility of poisoning.
The leak can not be found. Safe and easy
The job is done on ground; there is no possibility of poisoning. The leak can be seen, and can be mended directly.
To mend the water leak of the digester Dangerous
The digesters outlet is too small that the air circulation in the digester is bad. So, there is a possibility of poisoning. Safe
The digesters outlet is large enough that the air circulation in the digester is good. So, there is no possibility of poisoning. 5）Durable：
The concrete digester can last over thirty years. The glass fibre reinforced plastic gas-holder can last over ten years. When the gas-holder is worn-out, a new one can replace. So the Puxin biogas plant can last over thirty years. 6）Excellent safety feature：
There is no possibility of biogas poisoning to the users. When the gas-holder is taken out from the digester, there is no biogas left in the digester. The digesters outlet is 1.5m in diameter that is large enough to keep sufficient fresh air in the digester. So, it is safe to repair the digester, and safe to replace fermentation material. 7）Low cost
The cost to build Puxin biogas plant is lower than cost to build traditional Chinese fixed dome biogas plant and much lower than the cost to build Indian floating gasholder biogas plant.
