The technology comprises the following steps: seawater is delivered to a high cistern by a seawater pump; the seawater in the high cistern is delivered to a system for water supply through a water supply tube and a condenser inlet tube; the seawater is heated to a certain temperature by adsorbing latent heat of steam in an evaporator through all condensers of the system, and enters the evaporator after being heated to a designed temperature by a rapid heater with solar energy; the seawater enters the evaporator, becomes superheated water and is gasified rapidly and partially because a pressure in the evaporator is controlled to be lower than a saturation vapor pressure corresponding to a temperature of hot seawater; and a part of ungasified hot seawater enters a next stage evaporator and a part enters heat-collecting tubes at two sides of the evaporator. The heat-collecting tubes are provided with annular imbibition films, and the hot seawater flows from top to bottom after entering the heat-collecting tubes. In a flow process, the hot seawater is delivered to upper half parts of inner cavities of the heat-collecting tubes because of capillary imbibition actions of the imbibition films. The hot seawater is evaporated to steam because the heat-collecting tubes have a high temperature under the sunlight, the steam rises along the inner cavities of the heat-collecting tubes and enters the condenser to obtain fresh water which flows into a fresh water tank and then is output by a fresh water tube. Unevaporated concentrated seawater enters a concentrated water tank and is ouput by an inlet/outlet tube.
