Abstract
The salt water distillation system includes a sprinkler to form a mist of salt water over a distillation plate. The distillation plate is heated by applying electrical current to a heating coil. The steam is transferred to a condensation chamber and condensed fresh water is collected. During the desalination process, salt impurities are deposited on the hot distillation plate. A sludge remover, i.e., a steam head and movable ram, is provided to clean the distillation plate of the salt impurities. An exhaust fan is provided to cool fresh water condensate and lower air pressure in the system. Heat transferred from the steam during condensation is used to pre-heat the salt water to increase efficiency of the system.
Claims15
A salt water distillation system, comprising:
- a steam chamber;
- a sprinkler system disposed in the steam chamber;
- a salt water supply line connected to a salt water inlet pipe for delivering salt water to the sprinkler system;
- a distillation surface comprising a distillation plate disposed inside the steam chamber below the sprinkler system;
- electric heating coils for heating the distillation surface to form steam from salt water released as a mist by the sprinkler system and for maintaining the temperature of the distillation surface at approximately 400° F.;
- a movable steam ram disposed over the distillation plate for removal of deposits from the distillation plate, wherein the movable steam ram includes a steam cleaning head, the steam cleaning head being mounted on the movable steam ram, the ram being disposed in the steam chamber so that the steam cleaning head may be moved above and along the distillation plate, steam cleaning controls, the steam cleaning controls being provided to control forcible ejection of steam from the steam cleaning head during the distillation plate cleaning cycle;
- a condensation chamber, wherein the condensation chamber further comprises a steam cooling coils for heat exchange to condense the steam to provide fresh water;
- a steam outlet pipe for transferring steam generated in the steam chamber to the condensation chamber;
- a cooling tray for collecting distilled fresh water from the condensation chamber;
- a fresh water outlet pipe;
- an exhaust fan to assist further cooling of the fresh water in the fresh water outlet pipe;
- and,
- a heat transfer recycling system for transferring heat generated during condensation of the steam to pre-heat salt water supplied to the sprinkler system, the recycling system further including a heated air inlet in thermal contact with the steam cooling coils;
- and, a distilled hot water cooling tray being disposed proximate to a heat transfer area of an inlet water tank to facilitate pre-heating of the salt water in the inlet water tank.
