81. Experiment of a New Partitions Filler Regeneration Performance

The filler is the important heat and mass transfer components of dehumidifier and regenerator in liquid desiccant system. The traditional gas–liquid direct contact filler meets an unfavorable factor which is gas with liquid. In this paper, a new indirect gas–liquid contact partitions filler, which has a specific surface area of 286 m²/m³ and a porosity of 0.86, is proposed. Both regeneration performance of the partitions filler and 5090 wet curtain has been tested on a cross-flow regeneration module laboratory. LiBr solution has been used as the desiccant and the regeneration effect is described by regeneration rate, renewable efficiency, average mass transfer coefficient, and volumetric mass transfer coefficient. The influence of the regeneration performance of the system is analyzed with solution inlet temperature. A regeneration performance comparison of the new filler and the 5090 wet curtain has been carried out. It shows the volumetric mass transfer coefficient of the filler is 7–36 % higher than the 5090 wet curtain one when the solution temperature is between 43 and 60 °C, and the quality of air with liquid of the new filler is 58–87 % lower than the 5090 wet curtain one when the face velocity is between 0.387 and 0.645 m/s.
