应用玻璃钢制造沼气池具有很多优点,利用太阳能作为热源,解决了北方沼气池冬季产气少的问题。对太阳能玻璃钢沼气罐结构进行了设计,建立了力学模型,进行了力学分析,采用薄壳理论初步计算了玻璃钢沼气罐的壁厚,并运用有限元技术对壁厚进行了优化设计,降低了制造沼气罐材料的使用量,提高了安全系数;建立了太阳能加热系统的传热模型,计算出加热的效果。 The application of glass fiber reinforced plastic manufacturing digester has many advantages, the use of solar energy as a heat source to solve the problem of less gas production in the north biogas digesters in winter. The structure of solar glass fiber reinforced plastic gas tank was designed, the mechanical model was established, the mechanical analysis was carried out, the wall thickness of glass fiber reinforced plastic biogas tank was preliminarily calculated by thin shell theory, and the wall thickness was optimized by finite element method, Biogas tank material usage, improve the safety factor; set up a solar heating system heat transfer model, calculate the heating effect.
