Pujiang farmers invented biogas technology obtained national patent

He had opened trucks, sold agricultural resources, and sold pork. However, in recent days, he invented the constant pressure methane tank technology and obtained a practical technology patent certificate issued by the State Intellectual Property Office. A company in Nanjing bid for 1.2 million to purchase his patent. Deng Wancai, 57, is a farmer with a disability who comes from the Bajiaojing Village, Datang Township, Pujiang County.

Deng Wancai, who had a secondary school education, devoted himself to invention at home and after years of experimentation he finally made breakthroughs in biogas technology. At present, there are more than 100 households around the masses who have used his technology to build a new biogas digester.

Test success entrepreneurship training achievements patent invention

“At that time, the province was promoting tailor-made personalized services for people with disabilities, and a large number of employment techniques and entrepreneurial skills training were carried out.” After attending several entrepreneurial trainings, Deng Wancai learned a chance to learn from a friend about a rural digester. With the shortcomings of small gas storage, unstable gas pressure, and inconvenient scouring, he wondered if he could solve the problem through the training platform of CFLD. With the help of the Pujiang County Disabled People's Federation, he learned about the working principle of biogas digesters and their advantages and disadvantages.

Deng Wancai began his research on the new technology of biogas digesters in 2008. He gave up the closed structure of the former biogas digesters and ingenuity covered them with a plastic film in a pit in his own citrus plant.

The test at that time became a joke among the surrounding people. “You can produce gas like this and you have no one in the big road!” But in a few days, biogas would really bulge the membrane, so he designed it on the membrane. The air outlet, connected to the stove, can really ignite.

The success of the initial trial gave Deng Wancai a booster. "The key point at that time was to solve the problem of materials." Deng Wancai invented this technology and spent a lot of time looking for materials. After more than one year and found suitable materials, Deng Wancai successfully tested his relatives in Shalou Village, Chengjia Town.

Achievements Promotion Overall Planning Preparation for Scale Production

After Deng Wancai's constant pressure biogas digester test was successful, the surrounding people came to understand the situation. In 2010, he began to customize new types of biogas digesters for some large farmers. So far, he has produced more than 100 new types of biogas digesters.

The praise of the users made Deng Wancai firm with confidence in expanding the use of this technology. With the help of relevant people in the Pujiang County Disabled People Federation, he started to plan the promotion of this technology. “The acquisition of patents is just the beginning stage of my technology promotion. I am now setting up a company to look for investment and prepare for mass production. Will mainly target disabled people and drive them into employment.”

It is reported that Deng Wancai's company has entered the registration stage and is using Pujiang County Disabled People Federation to fight for Chengdu's relevant policies on the use of biogas new energy technologies in rural areas. At present, some districts and counties in Chengdu are already in contact with Deng Wancai, and they are ready to try to promote this new biogas technology. He said: "The disability of the body has caused great inconvenience to my usual work. It is not as good as the others and it is hard to look at and ignore. Perhaps the invention is a way out, to live, and to prove that the disabled are also strong. The spirit of fighting." (Europe Xiaoyang Liu Yang reporter Hongji Dongwen/Figure)
