Automatic water desalination plant, based on evaporation using solar collector and heat pump or Peltier element, using countercurrent principle for partial energy recovery

摘要

An automatic water desalination plant as in Claim 1 of (based on evaporation using a solar collector and a heat pump or Peltier element) is claimed, in which: (a) the countercurrent principle is used (13) for partial recovery of the expended energy, thus supporting the distillation process; (b) on exceeding a specific weight, density or driving action due to the increased salt solution concentration during distillation, the salt solution is evacuated; (c) fuel oil of b.pt. more than 270[deg]C and extremely low flammability is used as cheap and safe heat carrier; and/or (d) preheated salt water is supplied via a valve controlled by a float in the evaporation chamber.
