Vacuum distillation process and apparatus with direct air contact condensing for desalination of water
Abstract
Abstract A METHOD OR APPARATUS OF DESALINATING WATER WHICH COMPRISES HEATING SALINE WATER; PROVIDING THE HEATED SALINE WATER IN A FIRST CHAMBER; CONNECTING THE FIRST CHAMBER TO A SECOND CHAMBER WHICH IS AT A REDUCED PRESSURE; THE REDUCED PRESSURE FROM SAID SECOND CHAMBER CAUSING INCREASED BOILING OF SAID HEATED SALINE WATER IN SAID FIRST CHAMBER SO THAT THE SALINE WATER VAPORIZES RAPIDLY. THE VAPOR IS DRAWN INTO SAID CHAMBER BY THE PARTIAL VACUUM; THE FIRST CHAMBER AND THE SECOND CHAMBER ARE DISCONNECTED WHEN THE SECOND CHAMBER REACHES A PREDETERMINED TEMPERATURE AND ATMOSPHERIC PRESSURE IS THEN APPLIED TO THE SECOND CHAMBER TO CONDENSE THE VAPOR-STEAM CONTENT OF THE SECOND CHAMBER. THE V APOR IS IMMEDIATELY CONDENSED THEREBY PRODUCING AN AERATED DESALINATED WATER IN THE SECOND CHAMBER.
