摘要:
为了强化直接接触换热法高温吸附热泵生成过热蒸汽的效率,在反应器内分别设置了通道直径为反应器内径的10%和20%的传质通道。实验结果表明:与未加通道的实验结果作对比,加装10%内径的通道后,出口蒸汽温度的最高温度提高23℃,达236℃,蒸汽的生成量增加26%,蒸汽沸石质量比平均值增大14%,蒸汽生成的时间增加1.8%;加装20%内径的通道后,出口蒸汽温度的最高温度提高11℃,达202℃,蒸汽的生成量增加5.6%,蒸汽沸石质量比平均值几乎不变,蒸汽生成的时间增加25.3%,即大尺寸通道的蒸汽生成速率较快,小尺寸通道的蒸汽生成温度和质量较高。
Abstract:
Mass transfer passage was used inside the packed bed of enchance steam generation efficiency in a novel adsorption heat pump by utilizing a direct-contact heat exchange method. Ratios of the passage to inner diameter of the packed bed were 10% and 20%. Experimental results from 10% passage showed that the maximum generated steam temperature reached 236℃, which increased by 23?c compared to that without passage. Meanwhile the mass of steam mass increased by 26%, mass ratio of steam to dry zeolite(ms,out/mz) increased by 14%, and steam generation time increased by 1.8%. Experimental results from 20% passage showed that the maximum steam temperature only increased by 11?c; steam mass increased by 5.6%, ms,out/mzn was almost unchanged; steam generation time increased by 25.3%. Superheated steam generation rate was faster for large passage, while the maximum temperature and mass of generated steam were higher for small passage.
