Abstract
The present invention relates to a method for purifying a liquid comprising liquid particles and residual particles. It is hereby possible to generate substantially pure water from, for instance seawater.
Claims14
Method for purifying a liquid comprising:
- a) heating a liquid comprising a salt flow with at least one heating element;
- b) spraying the heated salt flow to form a liquid droplet flow and residual particles;
- c) applying an electric charge to both the liquid droplet flow and to a condensation surface;
- d) evaporating the liquid droplet flow wherein a water vapor flow and a residual particle flow are created;
- e) forming a condensate on the condensation surface with the water vapor flow;
- wherein the water vapor flow is guided to the condensation surface, and wherein the residual particle flow is repelled by the condensation surface;
- and
- f) discharging separately the condensate and the residual particle flow, wherein the condensate is discharged through the condensate surface.
5 more elements
A device comprising:
- a) a tube comprising a first portion and a second portion wherein the first portion comprises a condensation surface, and the second portion comprises a sprayer;
- b) a heating system comprising a heat exchanger wherein heat is released by a water vapor flow contacting the condensation surface and a heating element connected to the second portion;
- c) a first charge source connected to the sprayer and a second charge source connected to the condensation surface, wherein the first and second charge sources have the same charge;
- d) a condensate discharge system connected to the condensation surface;
- and
- e) a residual flow discharge system comprising a third charge source with a charge that is opposite the first and second charge source charge.
