Puxin Medium Size Biogas System Biogas Plant

Puxin medium size biogas system is mainly applied for small size livestock farms to treat the animal waste, for schools or factories etc. to treat waste water from toilets. The medium size biogas system is composed of a group of 10 m3 biogas plants that are formed into a unit, the pipe system, the gas purify system and the appliances or electricity generator.

Puxin Biogas Plant is of the hydraulic pressure biogas plant type, and is composed of a concrete digester and a glass fibre reinforced plastic gasholder. The digester has a capacity of 6 or 10 cubic meters, and is constituted by a stomach, a neck,an inlet and an outlet. The gasholder is 1.6 m in diameter, 1 or 1.2 cubic meter in capacity. The gasholder is installed within the digester neck, fixed by a component; the gasholder and the digester are sealed up with water.

Comparing with the traditional fixed dome type hydraulic Biogas plant, Puxin Biogas Digester has the following distinct advantages:
1) Easy to build and 100% success rate: The construction of Puxin Biogas Plant is exempt from the difficult airtight craft, so the technical difficulty is greatly decreased, and the construction perriod is greatly shortened. To build a Puxin Biogas Digester successfully, the constructers are only required to master how to assemble and disassemble the steel mould. Any workman can learn to build Puxin Biogas Digester within a day and with 100% success rate.

2) Suitable for vast rapid construction: The steel mould and the glass fibre reinforced plastic gasholder can be mass-produced in factories, so that any place or country can build the Puxin Biogas Plant on a vast scale

3) Convenient to replace solid fermentation material; suitable for straw and other solid organic material: The gasholder is only 30 kg in weight, and can eliminate the atmospheric pressure. So it is effortless to take out the gasholder from the digester, and easy to replace solid material through the digester neck (1.5m in diameter).

4) Easy to maintain and a long service life: When the gasholder is leaking, the leak can be found immediately, and can be repaired on ground. The concrete digester can last over 30 years , and the glass fibre reinforced plastic gasholder over 10 years. When the gasholder is worn out, a new one is replaceable, so that the biogas plant can last over 30 years.

5) Excellent airtight function and the high rate of biogas production: The glass fibre reinforced plastic gasholder sealed up by water is 100% airtight. Since replacing the fermentation material is easy, the digester can sustain sufficient fermentation material, so can the biogas plant have a high rate of biogas production.

6) Excellent safety and easy operation: When the gasholder is taken out, no biogas is left in the digester. The digester neck (1.5m in diam) is large enough to keep sufficient fresh air in the digester. So it is safe both to repair the digester inside and to replace fermentation material . When the gas pressure reaches its limit, there will be automatic gas leak, hence no damage to the plant.
