1. A direct-contact, spray-assisted, evaporation and condensation, DCSEC system comprising:
a heating block configured to receive and heat up seawater;
plural evaporation and condensation stages, each stage being configured to generate water vapors through flash evaporation;
an evaporation only stage connected to a last stage of the plural evaporation and condensation stages, the evaporation only stage configured to receive a brine from the last stage of the plural evaporation and condensation stages;
an input/output block configured to receive the brine from the evaporation only stage and to discharge the brine outside the system, and to receive cooling water; and
a pressure-swing regeneration block fluidly connected to the evaporation only stage to receive water vapor from the evaporation only stage and to generate a hot vapor, which is provided to the heating block for heating the seawater,
wherein a brine received by the last stage of the plural evaporation and condensation stages, from a previous stage of the plural evaporation and condensation stages, is mixed with water vapors from the evaporation only stage to generate bubbles, which are injected into an evaporator of the last stage of the plural evaporation and condensation stages.
