中国设备网特惠大放送抢先享受丝滑波纹填料提升您的生活品质

金属丝网波纹填料,作为全球范围内广泛应用的高效填料,其独特之处在于由多层平行且直列排列的金属波纹网片构成,形成一个圆盘状结构。每一片波纹网片的对轴线倾角通常设置为30度或45度,而相邻两片波纹方向呈反向排列。这使得金属丝网波纹填料拥有显著的优势:首先,它具有极大的比表面积和孔隙率,同时体积轻盈;其次,在气相通路方面,倾角保持较小,有规律且压降低廉;此外,它提供了良好的径向扩散性能,以及充分的气体接触,从而几乎没有低负荷极限,并且操作灵活性大。

这种特殊设计赋予了它在难以分离以及热敏性物质精馏中的卓越表现,使其成为常压精馏、真空精馏等领域不可或缺的一部分。metallic mesh fillings, a highly efficient filler widely used across the globe. Its unique structure consists of multiple layers of parallel and vertically aligned metallic wavy nets, forming a circular disk shape. The angle of each wave to the axis is typically set at 30 degrees or 45 degrees, with adjacent waves facing in opposite directions.

This design confers several advantages on metal mesh fillings: firstly, they have an extremely large surface area and porosity ratio, combined with a lightweight volume; secondly, in gas flow channels, angles are kept small and regular with reduced pressure drops; thirdly, radial diffusion is well facilitated for complete gas contact and almost no low-flow limit exists; fourthly, operational flexibility is high.

Such features make metal mesh fillings ideal for difficult-to-separate materials and heat-sensitive substances during distillation processes under normal pressure or vacuum conditions. They provide favorable conditions for precise distillation separation of high-purity products.

Specifically:

X-250 model offers high strength and fewer theoretical plates suitable for precise distillation.

X-500 model excels at vacuum distillation particularly below 7KPa.

Y-700 model is designed for separating isotopic mixtures or homologous mixtures.

Metal Mesh Fillings Performance Parameters:

| Model | Peak Height (mm) | Specific Surface Area (m²/m³) | Bulk Density (Kg/m³) | Void Fraction (m³/m³) | Pressure Drop per Plate (Pa/n) | HETP/mm |

| --- | --- | --- | --- ||--- |

| 250X |12 |250 |-125 ||95 |

|500X |-6.5 |-500 |-250 ||90 |

The performance parameters listed above demonstrate that this type of filling material can be tailored to suit various applications while maintaining its core benefits as described earlier.
