Correct selection and use of soft biogas digesters
The correct selection and use of soft biogas digesters, how much money is needed for the introduction of soft biogas digesters, collapsible biogas bags, biogas process flow chart, rural biogas equipment purchase, software biogas digesters, please call Hongjing Environmental Protection Manager Based on the research and analysis of the traditional wintering technology of the northern soft biogas digesters, a new type of low temperature biogas digester technology was explored and invented, and a series of experimental studies were carried out. Comparing with the gas production in the traditional biogas digesters in winter, the results show that the gas production by the low temperature resistant biogas digesters can be increased by about 3 times compared with the conventional thermal biogas digesters, and the average daily gas production of the low temperature resistant biogas digesters is 0.523 m3, which can guarantee the biogas digesters. The normal gas production in winter solved the technical problem that the northern soft biogas digesters could not operate normally in winter. In recent years, due to the country's strong investment and support, and the continuous research and development of biogas science and technology, the construction of rural biogas digesters is changing with each passing day, and the recognition of the masses is constantly increasing. However, through investigations in Shandong, Hebei, Beijing, Tianjin and other regions, we found that the application of soft biogas digesters in the northern region is generally low or no gas production in winter. The overwintering problem of soft biogas digesters has become a bottleneck restricting the development of biogas in northern China. It is an important problem to be solved urgently in China's biogas industry. 1. The main practices and requirements of soft biogas digesters 1. The soft biogas tank wall is constructed as a double-layer sandwich brick wall with an internal masonry thickness of 120 mm and an external wall thickness of 53 mm. 2, the sandwich layer is filled with perlite, polystyrene particles, foam aerated concrete and other insulation materials, the thickness of the interlayer is 60 ~ 100mm. 3. Place a 6.5mm long length steel bar in the 2~3 layer brickwork under the wall zui to ensure the carrying capacity of the bottom wall. 4. A reinforced concrete ring beam is placed on the top of the sandwich wall, and the load on the pool arch is transmitted to the pool wall and the surrounding foundation through the ring beam. 5. If the groundwater level is high, the waterproof layer at the bottom of the pool should be made on the sandstone cushion. The waterproof area is the entire bottom of the pool; the waterproof layer of the pool wall is made on the outer surface of the outer masonry. The height of the waterproof layer of the pool wall should be higher than that of Zui. The water level is above 10cm. Second, the technical advantages of low temperature resistant soft biogas digesters The technical advantages of low temperature soft biogas digesters: Blocking the heat exchange between the soft biogas pool heat and the outside cold air; 2. Overcoming the heat loss caused by groundwater; 3. Insulation material One-time investment can choose different insulation materials and build corresponding pool wall thickness according to the temperature requirements of different regions, which can reduce the cost relatively.
