This paper deals with engineering investigation and equipment design of a new multi-stage distillation system. The facility was designed in UDES center with the objective of increasing its productivity and improving its efficiency. Distillation device consists one of important process to produce fresh and clean water from brackish water that is abundant in many remote areas of south Algeria. In general, the production rate of the conventional solar still shows a daily production of 5 l/m2d which depends strongly on the material used and equipment design together with different factors. In comparison, Multi tray still mounted with four stages is more profitable in term of the output than a simple still. The various results, from which the effect of the boiler temperature Tb is presented in the range 75°C<Tb<95°C. The obtained results show that the first tray of the system produces about 33 liters of fresh water per day when the temperature of the evaporator efficiency is fixed at 96°C. Determinations of the output of each tray of the still are presented in this study. In fact, experimental data suggests that the tray number have a limit number to achieve a highest throughput with a most compact system. The analysis of the distilled water showed that its quality was within the international standards. We notice that water desalination with multi stage equipment is a good solution for a better output. |
