建立了溶液再生式蒸发冷凝器实验台,利用冷凝热再生氯化锂除湿溶液,对影响空气与除湿溶液之间传质系数的主要因素进行了实验测试。在大量实验数据基础上,分析了除湿溶液质量流速及空气迎面风速对空气与液膜之间传质系数的影响,并回归得到了传质系数的经验公式,为利用低品位热源再生除湿溶液提供理论依据。
The experiment bench of solution regeneration evaporative condenser was set up, and the main factors influencing the mass transfer coefficient between air and dehumidification solution were experimentally tested by condensing heat regeneration lithium chloride dehumidification solution. Based on a large number of experimental data, the influence of the mass flow rate of the dehumidification solution and the oncoming air velocity of the air on the mass transfer coefficient between the air and the liquid film was analyzed and the empirical formula of the mass transfer coefficient was obtained by regression. In order to provide the regeneration dehumidification solution with low- Theoretical basis.
