| 摘 要： | 将亲水无纺布PVC复合规整填料作为溶液除湿塔芯体，开展亲水无纺布PVC复合规整填料除湿性能实验，分析在不同空气流量、溶液流量、溶液温度下，亲水无纺布PVC复合规整填料除湿率、除湿效率、传质系数和传热系数的变化。在实验条件下，除湿率、除湿效率、传质系数、传热系数最大值分别为11.05 g·kg-1、86.7%、12.95 g·(m2·s)-1、10.33 W·(m2·℃)-1；与CELdek规整填料和塑料波纹孔板填料相比，亲水无纺布PVC复合规整填料除湿性能最优。对实验数据回归分析，得到亲水无纺布PVC复合规整填料除湿效率实验关联式。

| Abstract: | The hydrophilic non-woven PVC composite structured packing is used as the core of the solution dehumidification tower, and the dehumidification performance test of the hydrophilic non-woven PVC composite structured packing is carried out. The change of dehumidification rate, dehumidification efficiency, mass transfer coefficient and heat transfer coefficient of hydrophilic non-woven PVC composite structured packing under different air flow, liquid flow and liquid temperature were analyzed. Under experimental conditions, the maximum values of the dehumidification rate, dehumidification efficiency, mass transfer coefficient, and heat transfer coefficient are 11.05 g·kg-1, 86.7%, 12.95 g·(m2·s)-1, 10.33 W·(m2·℃)-1, respectively. Compared with the CELdek structured packing and plastic corrugated-hole plate packing, the hydrophile non-woven PVC composite structured packing has the best dehumidifying performance. The experimental data were regressed to obtain a dehumidification efficiency correlation formula of a hydrophilic non-woven PVC composite structured packing. |
