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.
