Gas film grain silo is a new type of grain storage method with significant technical advantages and application prospects. The following are its core features and technical details:1. Structure and construction characteristicsHigh strength membrane materials (such as PVDF) are combined with reinforced concrete thin shell structures to form a multi-layer composite structure that combines sealing and stability. Fast construction speed:Inflatable molding only takes 20 minutes, mechanized construction is not affected by weather, and the entire life cycle operation and maintenance cost is reduced by more than 30%.. Large span beamless design, high space utilization, single warehouse capacity up to 9000 tons, warehouse capacity increased by 20% compared to the previous generation. 2. Performance AdvantagesAirtightness:The pressure half-life reaches 4312 seconds (national standard 300 seconds), and the waterproof and moisture-proof performance is superior.. Thermal insulation:The heat transfer coefficient is only 0.4403W/m2/K, which is one-third of that of traditional shallow circular warehouses, achieving low-temperature storage (grain temperature of 15C).Environmental protection:With less construction dust, it can be disassembled and relocated, which is in line with the trend of low-carbon storage.. 3. Integration of grain storage technologyNitrogen controlled atmosphere: High purity nitrogen gas is filled to create a low oxygen environment, which inhibits pests and grain respiration, and has a significant effect on pest prevention and preservation.. Intelligent temperature control:Combined with grain cooling system, energy consumption is reduced by 4.33% compared to traditional warehouse types, and air conditioning temperature control energy consumption is halved.. 4. Application CaseFive 9000 ton gas film grain silos in China have been put into use in Changsha, successfully storing soybeans and other grains with significantly better grain quality than traditional silo types.. The design of the overhead gas film silo solves the problem of food preservation in the high temperature and high humidity environment in the south, and a single silo can meet the annual food needs of 70000 people. 5. Challenges and improvement directionsNeed to enhance adaptability to extreme weather (such as typhoons) and improve wind pressure resistance.. In the initial stage of promotion, it is necessary to strengthen market awareness and optimize technical performance through joint research and development.
