- Abstract
A seawater distiller utilizing the thermal energy of solar radiation and waste gas from a small electric generator was designed and constructed with a number of configurations to improve its performance. The distiller constructed is a combined model of a basin-type solar still and a vertical multiple-effect diffusion still, consisting of a series of closely spaced parallel plates in contact with saline-soaked wicks. Evaporation and condensation processes were repeated on all the plates by recycling thermal energy to increase distillate productivity in the still. Tests were performed with waste heat of actual exhaust gas from a portable electric generator, changing various experimental conditions such as feeding flow rate of seawater to the wicks, seawater level of the basin, and use of reflecting plate fins. Experimental results show that our two-effect distiller produces 17.1–19.6 kg/(m2 d) at 3,000 kJ/h and has a Performance Ratio of 14.8–16.9.
