| 摘 要： | 填料是化工气液传质设备中的核心组成部分，其作用主要是为气液或液液两相提供充分的接触面，强化两相间的传质或传热过程．填料的结构和性能对填料塔的技术经济指标具有决定性的影响．陶瓷填料具有耐腐蚀、价格低廉、润湿性与热稳定性好等特点．但其加工性能差，只能做成简单形状，与其他材质的填料相比，比表面积和空隙率都比较小，流动阻力大，传质性能较差，使其应用受到了一定的限制．

| Abstract: | Traditional ceramics packing has the shortcomings such as low porosity, small specific surface area and high bulk density. The foam ceramics ring packing DX-1 with 0.4 height to diameter ratio was designed according to the characteristics of foam ceramics and stainless steel packing.DX-1 has a porosity of 92%,specific surface area of 1825 m2•m-3 and bulk density of 208 kg•m-3.In the desorption column with diameter 200 mm, air was used to desorb oxygen-enriched water.The hydrodynamic and mass transfer performance of DX-1 was investigated.When liquid spray density(L) was more than 50 m3•m-2•h-1, the pressure drop of DX-1 decreased by 55%—62% and（HOL） 25℃ of DX-1 decreased by 12.7%—15.5% comparing to the stainless steel Pall ring packing.The hydrodynamic and mass transfer performance of DX-1 were equal to the stainless steel Intalox saddle packing.DX-1 was superior stainless steel packing in the cost and corrosion resistance. |
