金属丝网波纹填料，作为全球范围内广泛应用的高效填料，其独特的构造使其在精馏分离领域展现出卓越的性能。由若干平行直列的金属波纹网片巧妙排列而成，这些圆盘状填料中的每一片都具有30度或45度倾角，相邻两片波纹方向相反。这项设计不仅保证了空间效率，还增强了物质流通和气体扩散。

金属丝网波纹填料之所以备受青睐，是因为它拥有显著的比表面积和孔隙率，以及轻盈且易于操作的特性。此外，它在气体通路方面具有一定的规则性和较小倾角，从而降低了压降。这种结构还促进了径向扩散，使得气体与物质接触更加充分，几乎没有低负荷极限，操作灵活性也非常大。

metallic mesh wave filling material is widely used in the world, its unique structure makes it stand out in the field of distillation separation. The circular disc-shaped filler is composed of many parallel and vertical metal wavy net plates with a 30-degree or 45-degree angle to the axis, and the direction of adjacent two wavy plates are opposite. This design not only ensures space efficiency but also enhances material flow and gas diffusion.

The advantages of metallic mesh filling materials are as follows: (1) high theoretical plate number, large throughput, low pressure drop; (2) good performance at low loads; (3) high operational flexibility; (4) no significant amplification effect; (5) able to meet the requirements of precise large-scale vacuum distillation devices for difficult-to-separate systems and heat-sensitive materials. It provides favorable conditions for separating difficult-to-separate systems, heat-sensitive materials, and high-purity products.
