中文摘要：
针对新型模块化催化规整填料（MCSP）Winpak-C,结合Fluent模拟结果,分析了Winpak-C中各单元产生的压降贡献大小.由于Winpak-C的骨架是开窗导流填料Winpak,因此Winpak-C的压降来源于Winpak.提出了6种压降贡献机理,分别是气体进入填料层的阻力损失、填料片内部阻力损失、气体流出下层填料盘的阻力损失、气体流入上层填料盘的阻力损失、气体在壁面流道变化的阻力损失以及气体离开填料层的阻力损失,分析了压降的主要贡献因素并对其进行优化与比较.同时,计算了总阻力系数与雷诺数、催化剂包的降低高度的关系.结果显示所提出的优化方法能较好地降低Winpak-C的压降,提高催化精馏塔的通量.
英文摘要：
The pressure drop mechanism of the recently designed modular catalytic structured packing（MCSP） Winpak-C was analyzed.As the Winpak-C was based on Winpak, its pressure drop was derived from Winpak accordingly.Pressure drop principles were deduced from the Fluent simulated results：head loss at the layer entrance,head loss of gas flow confluence and diffluence through windows,head loss due to gas flowing out of the junction,head loss due to gas flowing into the junction,head loss of wall effects,and head loss at the layer exit.The major causes of pressure drop were discussed,optimized and compared. Furthermore,relationships among total loss coefficient,Reynolds number and catalyst loading reduction were also investigated.The results indicate that the proposed method can reduce the pressure drop of Winpak-C and the capacity of the catalytic distillation column can be increased.
