Black film price for biogas digesters in pig farms

Description :

　　The construction cost of black film biogas digesters is low and the construction is convenient; Long residence time and good water output effect; PE film heat absorption performance number, high gas production; Ultra large gas storage capacity, achieving integrated gas storage; It can effectively achieve the function of slag discharge.

　　Black film biogas digester, scientific name "fully enclosed anaerobic pond", is an important part of the biogas production equipment in aquaculture farms. The capacity of this biogas digester is 15000 cubic meters, with a black film on the ground and a top height of four to five meters. The anaerobic pond has a total depth of over 10 meters and a water depth of seven to eight meters. All the floating on the water is biogas. The black film with a thickness of only 1.5 millimeters is like a pot lid, covering the biogas inside and preventing it from leaking out. Biogas can be converted into electrical energy for production and daily use such as lighting, cooking, and pig house insulation in breeding farms.

　　The power of this pig farm's black film biogas digester is extraordinary: the gas holder can only store 200 cubic meters of biogas and can only generate 3 to 4 hours of electricity per day; The black film biogas digester can store two to three thousand cubic meters of biogas and generate electricity almost all day long. Black film biogas digesters have the advantages of large anaerobic fermentation capacity, long sewage retention period, large biogas production, and low operating and treatment costs. They are very suitable for the treatment of livestock excrement in large-scale farms and "water bubble manure" process farms. There are many benefits to building a black film biogas digester, the most obvious of which is that it has a large capacity and can store 10-20 times more waste liquid and biogas than conventional biogas digesters.

　　It has natural advantages in terms of construction cost, maintenance and management, as well as gas production, power generation, sewage treatment and other aspects, thus having strong economic, social and ecological benefits.

　　The biogas produced by the black film biogas digester in pig farms is a colorless, odorous, toxic, and odorous gas. Its main component, methane/alkane, is a colorless, odorless, odorless, and non-toxic gas at room temperature. The molecular formula of methane/alkane is CH4, which is a simple hydrocarbon compound composed of one carbon atom and four hydrogen atoms. The weight ratio of methane to air is 0.54, which is about half lighter than air. The solubility of methane/alkane is very low. At 20 ℃ and 0.1 kPa, 100 units of water can only dissolve 3 units of methane/alkane.

　　The methane/methane in the black film biogas digester of a pig farm is a simple organic compound and a gas fuel. When burning, it emits a blue flame and can reach a high temperature of up to 1 ° C? 400? Around ℃. The calorific value of pure methane/alkane per cubic meter is 36.8 kilojoules. The calorific value of biogas per cubic meter is about 23.4 kilojoules, which is equivalent to the heat released after fully burning 0.55 kilograms of diesel or 0.8 kilograms of coal. From the perspective of thermal efficiency analysis, the amount of heat that can be utilized per cubic meter of biogas is equivalent to the amount of heat that can be utilized by burning 3.03 kilograms of coal.

　　In the construction of black film biogas digesters, it is particularly important to strengthen the inspection of the joints of polyethylene geomembranes, so we can conduct inspections based on visual inspection and on-site leak detection methods. After welding the biogas digester membrane, check for any missing connections, whether the seams are burnt, whether there are wrinkles, and whether the splicing is uniform. On site leak detection uses the inflation method to inspect all welds. After inflating and observing for about one minute, adjust/check the vacuum gauge. If there is no decrease in air pressure, it indicates that there is no leakage and the welds are qualified. Then, leak detection and repair can be carried outBlack film of biogas digester.

　　Black film biogas digesters are an important part of many biogas production facilities in livestock farms. There are already many demonstration projects nationwide. This technology was introduced to China in 2003 and has been highly praised by many livestock farm owners. This process technology has a large gas production capacity, low cost, and can effectively degrade the concentration of COD and BOD in wastewater.

　　The biogas digester is excavated and constructed, with anti-seepage membrane laid at the bottom. The anti-seepage membrane has a good anti-seepage effect and will not pollute groundwater. The top is covered with black membrane for full sealing, significantly reducing odors and protecting the surrounding environment. Biogas can be converted into electricity to keep pig houses warm, provide lighting and cooking electricity for livestock farms, and be used as fertilizer for growing vegetables and fruits. Biogas residue can be directly discharged into fish ponds as feed.
