1, good thermal insulation, suitable for northern use. The thermal conductivity of concrete is 5.44kj/m.h.℃, and that of ordinary FRP is 1.42 kJ/m. h .℃. The wall of glass fiber reinforced plastic ellipsoidal insulation biogas digester is made into honeycomb insulation layer according to the vacuum insulation principle of thermos bottle, and the thermal conductivity is 0.59kj/m.h.℃, which is only 1/9 of concrete. The application effect of more than five years proves that gas can still be produced when the ambient temperature drops to MINUS 30℃.
2, the ductility is good, and the pool body is not afraid of freezing. Ground freezing will lead to the damage of concrete biogas digesters. However, all parts of the glass fiber reinforced plastic ellipsoidal insulation biogas digester are made of pure glass fiber reinforced plastic materials and bonded with pure glass fiber reinforced plastic putty (the whole tank body does not need screws). The expansion coefficient of tank material is consistent, and the tank wall is malleable and will not freeze.
3, the rigidity is very strong, and the pool body is firm and durable. Ordinary glass fiber reinforced plastic products have good toughness and insufficient rigidity, while glass fiber reinforced plastic ellipsoidal insulation biogas digester adopts honeycomb glass fiber reinforced plastic composite material, which enhances rigidity and improves bearing capacity and will not collapse during use.
4, good sealing, the pool body will never leak. Glass fiber reinforced plastic ellipsoidal insulation biogas digester is made of glass fiber reinforced plastic modified technology, which has better compression resistance, wear resistance and aging resistance than ordinary glass fiber reinforced plastic products, never cracks and does not need maintenance during use. Combined with underground anaerobic use, the service life can be up to 30 years.
5, acid and alkali resistance, adapt to different regions. The glass fiber reinforced plastic ellipsoidal insulation biogas digester was tested in Laoting coastal area, saline-alkali area and low water level area in Tangshan, especially in winter, showing good cold resistance, acid resistance and alkali resistance.
6. The pool is light in weight and easy to transport and install. Glass fiber reinforced plastic ellipsoidal insulation biogas digester, the tank body is composed of five pieces, the total weight is only about 200 kg, the transportation is convenient, the installation takes only half a day, and the filler can be used the next day after installation. Under normal circumstances, gas can be generated and ignited on the third day after sealing the pool.
7. Reasonable design and sufficient gas supply. The products of glass fiber reinforced plastic ellipsoidal insulation biogas digesters meet the announcementNo. 1 177 issued by the Ministry of Agriculture on March 9, 2009, which promulgated the agricultural industry standard of the People's Republic of China, namely NY/T 1699-2009 "Technical Conditions for Glass Fiber Reinforced Plastic Household Biogas Digesters". The depth of the tank is shallow, and the fermentation bottom is large, which facilitates the circulation of feces and has no fermentation blind area. The tank is also designed with a large gas storage chamber and a large water pressure chamber, which can increase the safety pressure of the biogas digester to 18 kPa (the safety pressure of the concrete tank is 12 kPa), and the gas production can reach more than 60% day and night, and the methane content of the generated biogas is also more than 60%.
8. Advanced technology and full fermentation of raw materials. Glass fiber reinforced plastic ellipsoidal insulation biogas digester adopts the new technology of hydraulic spinning liquid stirring, and utilizes biogas production power and dynamic continuous fermentation process to realize efficient operation such as automatic circulation, automatic stirring and automatic slag discharge. There is no need to add any stirring and slag pumping devices in the pool, so it is very convenient to be used as a "fool". 6, 8, 10 cubic meter glass fiber reinforced plastic ellipsoidal insulation biogas digester products were jointly selected as excellent products by China Rural Energy Industry Association, China Biogas Society, China Energy Conservation Association and China Agricultural Engineering Society.
9. Low cost, economical and durable products. Glass fiber reinforced plastic ellipsoidal insulation biogas digester uses industrial waste as composite material, which reduces the cost by about 35% compared with ordinary glass fiber reinforced plastic technology under the same volume and thickness.
10, complete sets, a wide range of products. In addition to supporting the existing stoves, lamps, rice cookers and showers, glass fiber reinforced plastic ellipsoidal insulation biogas digesters also require biogas boiler companies to develop biogas hot stoves and biogas boilers. Biogas stove can heat vegetables in 500 square meters greenhouse, and biogas boiler can heat three standard rooms in winter.
