PUXIN BIOGAS PLANT WON 2006 BLUE SKY-AWARDS
Our Products
Our company is a specialized biogas company. We develop biogas system, and the related equipments and products to build the biogas systems. The following are the biogas system-the Puxin biogas system we developed .
Puxin family size biogas system
| Puxin medium size biogas system |
| Puxin big size biogas system |

1.Introduction of Puxin family size and medium size biogas systemPuxin family size biogas system is mainly applied to farmer’s home. The family size biogas system is composed of a 6 or 10 m3 biogas plant , the pipe system, the gas purify system and the appliances or electricity generator.
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.
For Puxin family size and medium size biogas system, we sell all the necessary equipments and products needed to build the system and train technicians for our customers. Our customers build the biogas system with our equipments and products for their customers. The following are the equipments and products needed to build Puxin family size and medium size biogas system: |
| This product is composed of a number of steel moulding boards, and is used to construct the concrete digester. By using a steel mould，a 6 or 10 m3 puxin biogas digester can be built within 48 hours. The steel mould is reusable and can be used over 2000 times, last over ten years. It is very easy to build the concrete digester with the steel mould, because the constructers need no blueprint, and working on the steel mould is the only skill required. Thus, using the steel mould can greatly increase the speed and quality of the concrete digester construction. |

| The glass fibre reinforced plastic gasholder. |
| The glass fibre reinforced plastic gasholder is one of the main components of Puxin Biogas Plant, whose function is to collect and store the biogas produced in the digester. The gasholder has a valume of 1.0 m3 or 1.2 m3 . 1.0 m3 gasholder is for 6m3 biogas plant and 1.2 m3 gasholder is for 10m3 biogas plant. The gasholder can last over 10 years |

| Introduction of the family-size Puxin Biogas Plant |
 | 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. |
| The construction process of Puxin Biogas Plant |
| |  | | 2. assemble the stomach mould | | |  | | 3. Assemble the vault mould | | |
 | 4. Cast the
digester stomach | | |  | 5. Assemble the
neck mould | | |  | 6. Cast the
digester neck | | |
| |  | 8. build the
inlet and out

gas holder | | |
| The contrast of the technical requirements for the builders |
| The Contrast of the construction period |
| 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 |
 | A workshop of the glass fibre reinforced
plastic gasholder | | |  | Products ready to leave the
factory | | |  | | A workshop of the steel mould | | |
| 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). |
| The Contrast of fermentation materials allowed: |
| 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. |
| Contrast of the maintenance : |
| 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. |  |
| (3) Promotion Status | | 1) China market: Already extended to Shenzhen , Guizhou, Hunan, Guangdong, Fujian, Hubei, Anhui, Beijing and Xinjiang provinces. | |
