Application and performance analysis of the novel flow-guided vertical packing tray

为了实现大通量、高效率的目的,本文根据复合塔板的设计思想,开发设计了新型导向立体板填复合塔板(Novel FVPT).在一个直径为500 mm的有机玻璃塔内,使用空气-水(富氧水)物系对该塔板进行冷模实验.实验内容包括清液层高度、干板压降、湿板压降、雾沫夹带、漏液以及传质效率,研究其流体力学性能和传质效率随着气液相负荷的变化规律.本文还根据压降产生原理,结合影响塔板压降的因素,推导出了新型导向立体板填复合塔板干板压降的理论模型.此外,将新型导向立体板填复合塔板在化工生产中进行实践应用,扩大了工业产量,提高了分离效率,为企业和社会带来了经济效益和环境效益.

In order to achieve higher throughput and better tray efficiency, this paper proposed a new type of flowguided vertical packing tray, referred to as Novel FVPT, according to the design idea of composition. The novel tray was subjected to a cold mode experiment using an air-water（oxygen-enriched water） system in a 500 mm diameter Plexiglas column. The experiment included the clear liquid height, the dry pressure drop, the total pressure drop, entrainment,weeping and mass transfer efficiency. The correlation of the performance of the novel tray with the two-phase loading was invested in this work. Based on the mechanism of the pressure drop, the fundamental model of dry pressure drop of the novel tray was proposed. In addition, the industrial application of the novel tray was illustrated. The results showed that the novel tray with high throughout and better tray efficiency brought great economic and environmental benefits.
