Abstract

A simple, portable and efficient water desalination device uses deep ocean water, solar energy and the dynamics of generated secondary vortices. The device includes a tower, a heat exchanger positioned inside the tower near the top of the tower, a cold water source, a cold water receiving tank, a condensate catchment grille, a freshwater collecting tank, a rotor extending upward between the side walls of the tower from a lower portion of the tower, a power source for driving the rotor, a warm salt water pan positioned in the bottom of the tower and a warm salt water source. The cold water source is cold deep ocean water that is siphoned to the top of the tower through rollable, transportable fabric pipes. The warm salt water source is solar heated ocean water. In the tower, a hurricane is simulated by a rotating column that induces a circulation of air which approximates that of a hurricane. The rising warm vapor contacts the cold plate of the heat exchanger, condenses into droplets on the plate, and collects in a reservoir. That process is accomplished without consuming ocean water nutrients. Multiple desalination devices are placed on a barge to create a mobile vortex-principal desalination plant for military operations and other temporary or emergency applications.
