阶梯环填料-阶梯环参数规格尺寸表

阶梯环填料

阶梯环是一种用于填料塔的环形工业填料，广泛应用于石油、化工、氯碱、煤气及环保等行业的塔器中，其材质包括塑料、陶瓷和金属，常见规格为Φ16mm至Φ76mm。阶梯环高径比约为鲍尔环的一半，一端设计有锥形翻边结构，使堆积时接触方式由线性变为点接触，从而降低气体流动阻力并增大空隙率（85%-97%）...

阶梯环是一种用于填料塔的环形工业填料，广泛应用于石油、化工、氯碱、煤气及环保等行业的塔器中，其材质包括塑料、陶瓷和金属，常见规格为Φ16mm至Φ76mm。

阶梯环高径比约为鲍尔环的一半，一端设计有锥形翻边结构，使堆积时接触方式由线性变为点接触，从而降低气体流动阻力并增大空隙率（85%-97%），提高通量和传质效率。材质差异影响内部结构：金属阶梯环采用弯向叶片状的舌片设计，塑料和陶瓷材质则分为米字形或井字形内筋。通过优化气液分布与压降控制，其传质效率较传统填料提升20%-50%，适用于吸收塔、脱硫塔及洗涤塔等场景。

壁厚：根据尺寸不同，壁厚一般为2-8mm，确保填料在高压、高流速工况下的稳定性。

堆积密度：受尺寸与材质影响，范围为600-1200kg/m³，影响塔设备重量与基础设计。

比表面积误差：生产误差通常控制在±5%以内，确保填料性能一致性。

应用场景

小尺寸填料：适用于精细化工、实验室吸收/解吸塔。

中尺寸填料：广泛应用于石化、环保行业的蒸馏、洗涤塔。

大尺寸填料：用于大型化工装置，如煤化工、天然气处理塔。
