为了对纳米纤维空气过滤膜进行有效的理论数值计算和分析,建立了纳米纤维膜空气过滤性能计算的分析系统。对该系统所采用的三维重构、过滤效率计算及过滤压降计算等算法进行研究。通过去噪处理、二值化、细化算法和离散化进行纳米纤维膜的特征提取,并通过对纳米纤维膜的特征信息定义、存储和可视化渲染实现三维重构。通过对颗粒物与纳米纤维的碰撞检测和力学分析判断颗粒物被纳米纤维膜捕获的数量进行过滤效率的计算。最后,根据泊肃叶定律和压降原理实现了基于SEM图像的过滤压降计算模块。针对纳米纤维膜的拓扑结构和厚度进行了数值计算与实验比对,对比结果表明,过滤效率计算误差在10%以内,过滤压降计算误差在20%以内,计算结果趋势与实验结果相符,能够反映不同拓扑结构的过滤性能差异。
To realize effective theoretical calculation and analyses of a nanofiber air filtration membrane, an analysis system was developed to calculate the air filtration performance of the nanofiber membrane. The 3D topology reconstruction algorithm, the calculation module of the filtration efficiency, and the calculation method of pressure drops were investigated. First, feature extraction of the nanofiber membrane was conducted using denoising, binarization, thinning algorithm, and discretization, and the three-dimensional reconstruction was realized through the definition, storage, and visual rendering of the feature information of the nanofiber membrane. Subsequently, through collision detection and mechanical analyses of particles and nanofibers, the number of particles captured by the nanofiber membrane was determined to calculate the filtration efficiency. Finally, according to Poiseuille's law and the pressure drop principle, a filtration pressure drop calculation module based on SEM images was realized. The numerical results of both the topological structure and thickness of the nanofiber membrane were compared with experimentally determined values. The comparison results show that the calculation error of filtration efficiency is less than 10%, and the calculation error of filtration pressure drop is less than 20%. The trend of calculation results is consistent with the experimental results, which reflects the difference in the filtration performance of different topologies.
