Biogas construction requirements: First, the principle of site selection The construction of household biogas digesters should be planned in a unified way with the construction of the courtyard, following the principles of biogas digesters, changing pigsty, changing toilets, changing the “three pools of one pool†to “three combinedâ€, and using biogas digesters and gas points (kitchens, etc.) The distance should generally be controlled within 20m. It should not be too far away. Minimizing the transition of the gas pipeline may affect the gas efficiency. Second, the pool construction requirements: 1, should choose the corresponding pool size to build a brick pool, the size should be slightly longer than the length of the soft pool size reduction 10-15cm, high is 5-10cm more appropriate. For example, if the size is 8 cubic meters, for example, the software biogas digester has a length of 3m, a width of 1.8m, and a height of 1.5m. When the actual tank is built, the net size of the cavity should be 2.90m in length, 1.7m in width, and 1.6m in height. 2. Regardless of the form of the pool, it must be paid attention and attention! note! Prevents the sharp hard object from piercing the flexible biogas generator. 3. The biogas digester is generally recommended to be below the ground and covered with a solar plastic shed. This will not only extend the service life, but also make full use of solar energy to increase the temperature of the fermentation tank. If the biogas digester is built on the ground level, the tank body must be sturdy, and it must withstand the pressure formed around the soft biogas digester. Otherwise, the tank body will explode due to excessive pressure and damage the soft biogas bag. 1. Open the soft biogas digester and lay it in a newly built tank or in an appropriate old tank body. 2. Put the PVC pipe on both ends of the soft biogas bag, and place the well-prepared PVC pipe in the reserved holes at both ends to seal it with cement. 3, the maximum amount of feed can not exceed the software digester (bag), the volume of 80%, the feed liquid within the fermentation tank should be higher than the feed port, overflow port 20-50CM to achieve a hydraulic seal. 4, good exhaust mouth 5. The outdoor pipeline shall be constructed according to the underground pipeline method, and the space between the pool body and other underground pipelines shall be at least 10cm apart. 6, indoor piping, according to the bright pipe installation. The indoor air pipe should be fixed to the wall with a pipe clamp. The distance between the pipe clamps should not exceed 100cm, and the horizontal pipe should not exceed 60cm; the height of the horizontal pipe should not exceed 200cm, and the slope should be no less than 10%. The direction of the pipe falls into the water; the gas pipeline shall not cross the open line of the electric wire. If the distance between the gas pipeline and the electric wire is not less than 10cm, the distance between the gas pipeline and the chimney shall not be less than 50cm. 7. Connect the air pipe and install the air-water separator, desulphurization purifier, booster pump and gas appliance in sequence. 8. When the software biogas digester (bag) is installed and put into use, it shall be covered with "insulation protection cover" on the top of the soft body tank. In winter, it will increase the temperature and keep warm, so that the biogas digester can produce more gas in winter. , to ensure that users use gas. The insulation protection cover can be used throughout the year, in addition to winter insulation, ultraviolet radiation can also be prevented in the summer, and can protect the pool from man-made or environmental factors, play a protective and safe role in extending the life of the pool.
