Abstract:

研制了一台能够连续制备蓄冷用CO2水合物的压缩式循环实验装置,并在该装置上研究了充注压力对水合物的预冷时间、生成质量、水合比例和潜热蓄冷量的影响。实验结果表明水合物在CO2气泡上升过程中生成,在气液界面处堆积。高的充注压力有着更理想的蓄冷特性,当充注压力为4.2MPa时,预冷时间为8min、水合物生成质量为8.44kg、水合比例为75.1%、水合物潜热蓄冷量为4.22MJ。充注压力为3.8MPa及以上时,水合物生成量大,水合物阻碍釜内各部分的传热,使釜内中层、下层的温差较大。水合物生成过程后期,水合放热量减少,液体CO2在反应釜内的蒸发吸热效应使得釜内温度继续降低,一直到低于0℃,充注压力越高,此现象越明显。
