EXPERIMENTAL STUDY OF HIGH GRAVITY ROTATING PACKED BED ABSORBER IN OPEN CYCLE ABSORPTION HEAT PUMP

研究在高湿烟气水、热回收过程中操作参数对超重力旋转填料床吸收器性能的影响。研究表明,一定范围内增大液气比、超重力因子和进口溶液浓度,降低进口溶液温度可提高潜热回收率（水回收率）。最佳操作参数为进液温度40～50℃,液气比1.0～1.6,超重力因子150～200,溶液质量分数为49%～51%。

Based on the open cycle absorption heat pump technology,which uses solar energy and other renewableenergy as driving heat source,for latent heat recovery from flue gas,a high gravity rotating packed bed（HG-RPB）isdeveloped.HG-RPB has excellent micro mixing and transfer enhancement properties,it can signally reduce the size ofabsorber in open cycle absorption heat pump.The results show that,in certain range,improving liquid to gas ratio,highgravity factor,the inlet solution concentration and reducing the inlet solution temperature can improve the latent heatrecovery rate（Water recovery rate）.Recommended operating parameters are：solution temperature 40-50 ℃,liquid togas ratio 1.0-1.6,high gravity factor 150-200,solution concentration 49%-51%.
