What are the economic and social benefits of soft biogas compared with traditional biogas?

—— Pilot popularization of flexible soft biogas in Shuimoba Village, Yinjia Town.

Convenient and fast: a pot of boiling water 10 minutes can be done.

"It was only a week before and after my family started using soft biogas digesters. On the first day, the technicians installed the biogas flexible pipe, and the next day, it vented. Our family uses biogas for cooking and boiling water ... "The wife of Yang Taixing, a farmer from Shuimoba Village, Yinjia Town, Bazhou District, walked into the kitchen and told reporters that she skillfully turned on the biogas stove, and her brow was full of joy. This is April 65438, 2005. The reporter saw at the scene that soft biogas is not only powerful, clean and hygienic, but also environmentally friendly, not backfiring and safe.

Lei lives in club 6 of Shuimoba village. She is a typical rural woman. She usually cooks, boils water and feeds pigs alone. Lei said, "In the past, people used firewood and coal as fuel. It is very inconvenient to get up before dawn to cook for your family and cook pig bile. It takes more than an hour to cook a meal. If tourists come, it will take longer, which will make people backache ... and cut down a lot of wood every year, which also destroys the ecological environment. Now it is convenient and clean to use soft biogas, and cooking and boiling water can be done in more than 0/0 minutes ... "

In the afternoon, the reporter came to Lei's home to learn about the use of biogas in her home. The reporter saw in the back of the house: I only saw a bite with a diameter of about 2. A circular pool about 2 meters deep and 5 meters deep is surrounded by cement bricks. There is a dark blue soft capsule in the middle of the pool, and a thumb-thick tube protrudes from the middle of the capsule. The technician said that this is a soft biogas outlet pipe.

Flexible and soft biogas: the cost per mouth is about 2000 yuan.

It is understood that flexible soft biogas is a new type of rural environmental protection energy, which is mainly composed of special composite materials, soft biogas fermentor, supporting biogas compressor, biogas pipeline and cooker software; It is characterized by acid resistance, alkali resistance, explosion resistance, earthquake resistance, economical use and convenient carrying; Flexible and soft cloth for biogas digester is a kind of polymer composite material suitable for biogas environment, which consists of two membranes and a middle cloth, and its service life is 18 years. The biogas slurry after soft biogas can also be used as feed to feed livestock and poultry.

According to the person in charge of Bazhong Multidimensional Agricultural Science and Technology Development Co., Ltd., compared with traditional biogas, flexible soft biogas has the advantages of mature technology, low cost, fast gas production, high gas production rate, large firepower, stable continuous gas supply and easy maintenance. With the passage of time and the development of technology, the current flexible soft biogas overcomes the shortcomings of exposure and easy damage of biogas digesters.

Li Qingquan, an engineer of Bazhong Multidimensional Agricultural Science and Technology Development Co., Ltd., introduced that flexible soft biogas saves money; The investment cost of flexible soft biogas is about 2000 yuan/pool, including 6 workers (60 yuan/Taiwan) in 360 yuan, brick or stone 200 yuan, inlet and outlet pipeline 70 yuan, and cement 0. 1 ton 54 yuan, 50 yuan, sand or slag 50 yuan, booster pump 130 yuan, soft water tank 1350 yuan, pipes and stoves 250 yuan. Simple installation, saving labor and time; 3-5 days to complete the installation and construction work, and use combustible fire; The biogas digester with long service life and good safety performance, brick-concrete structure and glass fiber reinforced plastic structure: has some shortcomings, such as natural damage, tree root damage, earthquake damage, inconvenient maintenance, crusting of decayed materials, unstable firepower, inability to shrink biogas digester solids, unstable air pressure, easy poisoning when refueling and cleaning biogas digesters, and easy bursting in cold and high temperature areas. Soft biogas is cold-resistant, high-temperature-resistant, explosion-proof (belonging to low-pressure tanks) and has good sealing performance. Rotten materials are not easy to crust, slag automatically, and are not poisoned if they are not put into the tank. The fermenter is covered with wooden sticks to prevent cigarette butts, firecrackers, sharp tools and other security risks from being damaged. Because of good sealing, good anaerobic environment of slag liquid and high gas production rate, there are no problems such as slow gas leakage and slow gas infiltration in traditional biogas digesters, and the biogas produced is 60% higher than that in traditional biogas digesters; Because the gas storage equipment used in soft biogas can be contracted, the pressurization equipment is added, and the air pressure is stable and the firepower is fierce when used.

Flexible biogas: the pilot project settled in Shuimoba Village, Yinjia Town.

According to Wang Jing, the mayor of Yinjia Town, Bazhou District, because flexible biogas is a new type of environmental protection energy, the pilot projects of Schell, Schell, Schell, Schell and Schell were mainly carried out in Shuimoba Village, Yinjia Town. At present, only 18 households are piloted in Shuimoba village, and will be gradually popularized in rural areas according to the wishes of the masses when conditions are ripe. Biogas has good economic and social benefits. Soft biogas combines toilets, pens and biogas digesters well, reduces the breeding of mosquitoes and flies, and completely changes the "dirty, chaotic and poor" sanitary situation in rural areas to a certain extent, which is consistent with the comprehensive management of urban and rural environment advocated now. Direct economic benefits, used for cooking and lighting, can save more than 500 yuan in cash a year. The indirect economic benefits are as follows: the "dung-marsh-fruit" ecological orchard model or "dung-marsh-courtyard economy" model can be developed, which can effectively alleviate the energy shortage in rural areas, solve the problems of fuel and fertilizer, reduce the pollution of pesticides and fertilizers, and protect and promote the ecological balance of forests; At the same time, the use of biogas fertilizer can improve soil, increase the content of organic matter, nitrogen, phosphorus, potassium and other elements, enhance soil acid activity, increase fertility, and promote the sustainable development of green food and agriculture; It can protect water sources, reduce pollution, build an agricultural ecosystem, free women from heavy kitchen work, free up more time for courtyard economic production, increase family income, and promote agricultural production and farmers' income.

Luo, secretary of the branch of Yinjia Township Neighborhood Committee in Bazhou District, said: "In the past, neighbors also built traditional biogas digesters, but now they are not used. A lot of manpower and financial resources were spent at that time. My family built this soft biogas digester, which used 700 bricks and 3 packages of cement, and only cost 400 yuan to 500 yuan. Usually, a family of three uses biogas to cook and boil water, which is very convenient, with low biogas cost, convenient and fast process, strong firepower and environmental protection. With soft biogas, it is equivalent to running a small fertilizer processing plant. After using this biogas digester, it has brought many changes to our family ... "
