How much does it cost to build a biogas digester?
Pool volume can be based on the local temperature, fermentation raw materials and other sources of specific planning. Cold winter in the northern region, gas production is lower than the south, the general household pool to choose 8 cubic meters or 10 cubic meters in the south, the home pool to choose about 6 cubic meters. The construction of biogas digesters in accordance with this standard, good management, spring, summer and autumn three and produced biogas, except for cooking, water heating, lighting can be more than winter temperatures, gas production decreased, can ensure the cooking needs. Some people think that "the greater the biogas tank repair, the more gas production", this view is one-sided. Practice has proved that there is no gas in the gas to "build" (Jian Chi), gas less gas in the tube (management). Biogas pool volume is large, if the fermentation of raw materials, scientific management measures can not keep up, gas is not as good as small pool. However, we can not simply consider the convenience of management, the biogas pool is very small, because the volume is too small, the impact of biogas digesters, fertilizer making function, which is unreasonable.
(2) proposed the construction scheme, construction drawings; (3) to build a pool of materials; (4) line; (5) excavation; (6) the formwork (external mold and an internal mold); (7) concrete, or brick, or precast concrete plate assembly (8); maintenance; (9) removal; (10) backfill; (11) sealing layer construction; (12) gas distribution pipe fittings, lamps, stoves installed; (13) pressure test and acceptance. All localities should according to local conditions, local materials, not force all. 2, the construction of large quantities of biogas digesters suitable? The biogas pool volume size (generally refers to the effective volume, the net volume of the main tank), should according to the daily number of varieties of raw materials, fermentation, gas production and gas production rate is determined, taking into account the quantity and use of biogas fertilizer. In rural areas, according to the average daily gas consumption per person 0.3 ~ 0.4 cubic meters, a family of 4 people, every day cooking, lighting need about 1.5 cubic meters of methane. If the use of good quality biogas lamps and biogas stoves, gas consumption can also be reduced. According to the practice of science and practice around the general requirements of an average amount of pig manure (about 5 kg) into the pool fermentation, that is, the planning of the construction of an effective volume of 1 cubic meters. Pool volume can be based on the local temperature, fermentation raw materials and other sources of specific planning.
Build a 8 cubic meters of biogas digesters on the $1000 or so, the construction of biogas digesters, what are the steps of the 1? (1) look at the terrain to determine the location of the methane tank;
