A desalinization apparatus, comprising: a first end and a second end in opposition to one another, a line between the first end and the second end forming an axis, with the first end forming: at least one port configured to receive an airflow therethrough and at a pressure higher than an ambient atmospheric pressure; and the first end forming at least one port configured to receive salt water therethrough and at a pressure higher than the ambient atmospheric pressure, and with the second end forming: at least one output for providing outflow of pure water vapor to a condenser so as to obtain pure water; and the second end forming at least one output for providing outflow of a mixture of water, salt and air; and at least one tube casing extending between the first end and the second end, the tube casing enclosing a plurality of chambers arranged in series with one another for evaporating the salt water into the airflow, with each of the chambers forming: a plurality of passageways arranged substantially parallel to the axis between the first end and the second end; and forming a plurality of ports from the passageways, with the ports arranged in a plurality of rows substantially parallel to one another; characterized in that: the plurality of ports are arranged substantially perpendicular to the axis between the first end and the second end; and the plurality of chambers are configured so that the airflow and salt water are directed through the plurality of ports to form a plurality of vortices about the axis in the plurality of chambers in series with one another to evaporate water vapour from the salt water into the airflow prior to providing the water vapour in the airflow to a condenser. a first end and a second end in opposition to one another, a line between the first end and the second end forming an axis, with the first end forming: at least one port configured to receive an airflow therethrough and at a pressure higher than an ambient atmospheric pressure; and the first end forming at least one port configured to receive salt water therethrough and at a pressure higher than the ambient atmospheric pressure, and with the second end forming: at least one output for providing outflow of pure water vapor to a condenser so as to obtain pure water; and the second end forming at least one output for providing outflow of a mixture of water, salt and air; and at least one tube casing extending between the first end and the second end, the tube casing enclosing a plurality of chambers arranged in series with one another for evaporating the salt water into the airflow, with each of the chambers forming: a plurality of passageways arranged substantially parallel to the axis between the first end and the second end; and forming a plurality of ports from the passageways, with the ports arranged in a plurality of rows substantially parallel to one another; characterized in that: the plurality of ports are arranged substantially perpendicular to the axis between the first end and the second end; and the plurality of chambers are configured so that the airflow and salt water are directed through the plurality of ports to form a plurality of vortices about the axis in the plurality of chambers in series with one another to evaporate water vapour from the salt water into the airflow prior to providing the water vapour in the airflow to a condenser. the plurality of ports are arranged substantially perpendicular to the axis between the first end and the second end; and the plurality of chambers are configured so that the airflow and salt water are directed through the plurality of ports to form a plurality of vortices about the axis in the plurality of chambers in series with one another to evaporate water vapour from the salt water into the airflow prior to providing the water vapour in the airflow to a condenser.
