Solar-powered humidification-dehumidification desalination system

A solar-powered humidification-dehumidification desalination system, comprising:

• a reservoir of saline water;
• a plurality of humidifiers disposed in successive stages from a first stage to a last stage, each of the humidifiers having a solar collector for heating air and a sprayer for spraying the saline water into the heated air, whereby pure water evaporates from the saline water to form heated humidified air;
• a dehumidifier stage for condensing water vapor from the heated humidified air;
• a system of air conduits connecting the humidifier stages and the dehumidifier stage, the system of air conduits being configured to circulate air from the first humidifier stage through the last humidifier stage to produce successive stages of the heated humidified air, and from the last humidifier stage to the dehumidifier for condensation of desalinated water from the heated humidified air, and back to the first stage humidifier to recycle the air;
• and
• a system of saline water conduits connecting the humidifier stages and the reservoir of saline water, the system of saline water conduits being configured to circulate the saline water sequentially from the last humidifier stage through the first humidifier stage to the reservoir of saline water.
