PUXIN Biogas Plant 4 6 and 10 m

PUXIN Biogas Plant 4, 6 and 10 m 3 family-size

(1) Introduction of PUXIN Biogas Plant technology § To renovate the traditional fixed dome biogas plant, Shenzhen Puxin Science& Technology Co. , Ltd, through many year’s study developed a new generational hydraulic biogas Plant-the PUXIN Biogas Plant that has carried on almost all the advantages of the traditional fixed dome biogas plant, and overcome its main disadvantages. § By the end of 2012, PUXIN biogas plant has been extended to over 50 countries.

A. The structure: § PUXIN Biogas Plant is mainly composed of a concrete digester and a glass fibre reinforced plastic gas-holder.

§ The digester is 2. 4 m deep, 2. 8 m in diameter and 6 m 3 of capacity. The gas-holder is 1. 6 m in diameter, 0. 6 m high and 1 m 3 of capacity .

B. Main advantages Comparing with the fixed dome biogas plant, the PUXIN biogas plant has the following distinct advantages: § Easy and quick to be built § High gas production rate § Easy to maintain § Durable

1. Easy and quick to be built § Any working mason through one day’s study is able to build the PUXIN Biogas Plant with 100% success rate. § The construction of a PUXIN Biogas Plant can be completed within 48 hours.

The process to build PUXIN biogas plant 1. Dig a hole in the grand 3. Assemble the vault mould 2. Cast the basement and assemble the stomach mould 4. Cast the digester stomach

5. Assemble the neck mould. 7. disassemble the neck mould. 6. Cast the digester neck 8. disassemble the vault and stomach mould

9. Build the inlet and outlet 10. Install the gas holder 11. Install the gas pipe system and the appliances

Contrast of the technical requirements for the builders Traditional fixed dome biogas plant PUXIN Biogas plant Airtight craft Highly required Not required Ability to understand blueprints Highly required（build by hand depending on 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 1 -5 days 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 100％ guaranteed Items

Contrast of the construction period Item Traditional fixed dome biogas plant PUXIN Biogas plant Construction of the 4 days concrete digester 2 days Airtight working procedure 10 days ( not required) The airtight test working procedure 4 days 0 days (notrequired) Total 18 days 2 days

2. High gas production rate § It has been proved that the gas production rate of PUXIN biogas plant is over 50% higher than that of the traditional fixed dome biogas plant in average under the same conditions. § In TIMOR LESTE a 10 m 3 PUXIN biogas plant with three 1. 2 m 3 gasholders can produce enough gas for three families.

3. Easy to maintain The leak of the gas-holder can be found immediately, and can be repaired on ground

Contrast of the maintenance Traditional fixed dome biogas plant PUXIN Biogas plant 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 Dangerous the digester The digester’ outlet is too small that the air circulation in the digester is bad. So, there is a possibility of poisoning. Safe The digester’s outlet is large enough that the air circulation in the digester is good. So, there is no possibility of poisoning. Items To mend the gas leak of gas-holder

4. 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.

1. Steel mould The 10 m 3 steel mould can build 4, 6 and 10 m 3 PUXIN family size biogas plants.

2. The gas-holder § This product is one of the main components of PUXIN Biogas Plants. § On the top of the gas –holder there is a valve that can eliminate the atmospheric pressure. § When there is a need to replace solid fermentation material like straw in the digester or to repair the digester, the gas-holder can be taken out from the digester easily.
