摘要
除湿溶液再生是维持除湿过程持续进行的必备条件,其效率直接影响整个系统的性能。借鉴水滴闪蒸理论,分析了液滴闪蒸过程大小、质量以及温度变化,初步实验测试了影响闪蒸效率的因素,结果表明:压力是影响闪蒸效率的核心因素,及时去除蒸发水分才能保证闪蒸的持续进行;溶液浓度配比与闪蒸效率关联性较强;液滴初始温度对闪蒸效率影响相对较小;温度的实验测试值总体大于理论计算值,使用水滴闪蒸理论模型需进行物性修正。
Regeneration of dehumidification solution is necessary to maintain the continuous dehumidifying process,whose efficiency directly affects the performance of whole system.The size,mass,and temperature of droplets during the flash evaporation were analyzed based on droplet flash theory,and the factors affecting the efficiency of flash evaporation were tested through preliminary experiments.The results show that pressure is the key factor affecting the efficiency of the flash evaporation.Flash evaporation may proceed only if the steam is removed timely.The mixed ratio of different solutions is relevant to the efficiency of flash evaporation.The initial temperature of droplet has little effect on the efficiency.The experimental values of temperature are higher than the theoretical values,so the physical properties need to be modified if the flash evaporation theory of droplet is adopted according to droplets flash evaporation of mixed dehumidification solutions.
