【摘要】：为了在盐水分离领域更高效地利用太阳能、地热及发动机余热等低温热源,参考传统海水淡化装置,设计一种将喷雾闪蒸、热管传热与固体吸附耦合集成的新型吸附式盐溶液水分离装置,并对氯化钠含量为3%的盐溶液进行水分离试验,结果表明:溶液经雾化闪蒸后温度骤降,接触热管冷端后吸收大量热量蒸发,该装置可利用40~100℃的低温热源,单级可分离盐溶液中18%~60%的水分;热源温度是影响分离率的关键因素;吸附剂的吸附作用在相同热源温度下可大幅降低闪蒸室蒸发压力,提高过热度;整个吸附及脱附周期内压力呈规律性变化,不仅受吸附床切换而骤变,还受闪蒸室热源与吸附剂内冷却水温度的变化影响;降低冷却水温度可明显降低蒸发室平衡压力,保证蒸发器内液滴持续蒸发,提高分离率。
[Abstract]:In order to make more efficient use of low temperature heat sources such as solar energy, geothermal energy and engine waste heat in the field of brine separation, a spray flash was designed with reference to the traditional seawater desalination device. A new type of adsorbed salt solution water separation device, which is coupled with heat transfer and solid adsorption, is developed. The water separation test of salt solution with sodium chloride content of 3% is carried out. The results show that the temperature of the solution drops sharply after atomization and flash evaporation. After contact with the cold end of the heat pipe, a large amount of heat evaporation is absorbed. The apparatus can use a low temperature heat source of 40 ~ 100 鈩，
