Evaporative distillation device comprising one or more distillation chambers arranged in series or in parallel, containing: - a heat source that blows hot dry gases into the chamber; - a condenser cooled by the solution to be treated; - a system of convection by thermosiphon or mechanical ventilation that sucks up the dry gases from the condenser in order to reintroduce them into the lower part of the chamber; the device being configured such that: - the distillation is carried out without wetting of the heat source, the solution to be treated being introduced into the distillation chamber using a nozzle system that produces a jet of droplets electrically charged by the application of an electric potential difference between a corrosion-resistant submerged electrode, located in the barrel of the nozzle, and an offset electrode located in line with this same barrel; - the distillation is carried out without contact of the droplets of solution with the walls of the chamber, the evaporation zone being entirely contained in an electrostatic confinement bottle configured so as to be charged to the same polarity as the submerged electrode, and so as to act by electric repulsion on the droplets; - the distillation is carried out without contamination of the condenser by the droplets of solution to be treated that are in suspension in the gases of the electrostatic confinement bottle, the walls of the bottle comprising, in the upper part, pores that let the gases escape towards the condenser, but the dimensions of which are small enough to form an impermeable electrostatic barrier to the droplets in suspension and also other pores in the wall of the bottle allow the entry of the gases originating from the heat source; - the residual solution, at the end of the evaporation process, has given up a large portion of its heat, which renders it less corrosive or scale-forming, so that the residual solution, no longer presenting a risk for the ducts of the device, can be discharged through a simple opening in the lower part of the bottle. - a heat source that blows hot dry gases into the chamber; - a condenser cooled by the solution to be treated; - a system of convection by thermosiphon or mechanical ventilation that sucks up the dry gases from the condenser in order to reintroduce them into the lower part of the chamber; - the distillation is carried out without wetting of the heat source, the solution to be treated being introduced into the distillation chamber using a nozzle system that produces a jet of droplets electrically charged by the application of an electric potential difference between a corrosion-resistant submerged electrode, located in the barrel of the nozzle, and an offset electrode located in line with this same barrel; - the distillation is carried out without contact of the droplets of solution with the walls of the chamber, the evaporation zone being entirely contained in an electrostatic confinement bottle configured so as to be charged to the same polarity as the submerged electrode, and so as to act by electric repulsion on the droplets; - the distillation is carried out without contamination of the condenser by the droplets of solution to be treated that are in suspension in the gases of the electrostatic confinement bottle, the walls of the bottle comprising, in the upper part, pores that let the gases escape towards the condenser, but the dimensions of which are small enough to form an impermeable electrostatic barrier to the droplets in suspension and also other pores in the wall of the bottle allow the entry of the gases originating from the heat source; - the residual solution, at the end of the evaporation process, has given up a large portion of its heat, which renders it less corrosive or scale-forming, so that the residual solution, no longer presenting a risk for the ducts of the device, can be discharged through a simple opening in the lower part of the bottle.
