Humidification - Dehumidification Process (Solar Distillation).

摘要

The planned investigations were intended to find out optimal conditions for obtaining fresh water from the sea water by the heating-humidification-dehumidification procedure, H-D,by applying some variants of the construction of stills of this type. An evaporator was constructed in which warm saline water flowed downward in the capillaries of hydrophilic gauze sheets. Countercurrent to the saline water flow,warm air flowed along the evaporator through spaces between the gauze sheets thereby saturating it with water vapor. The influence of the flow rate and temperature of both the saline water and air on the amount of water obtained was studied. Eighty experiments were carried out. The highest production of distilled water was obtained with a warm saline water flow rate of 11.7 l/h and a temperature of 75C,when combined with air flow rate of 16cu m/h at 110C.
