The invention relates to a dehumidification-type portable sea water desalination method for salvage. In the method, an air dehumidification-type portable sea water desalination device for salvage is used; and the device comprises a heat exchange module, a water preparation module, a power supply and control module, and an auxiliary module. Under the sun, a large amount of water vapor can be generated near the surface of the sea water, the air inlet of the device is formed near the surface of the sea water, and after being sucked into the device through a blower, the water vapor is condensed toform water droplets through the heat exchange device, flows into a primary water storage tank, then flows into and is stored in a secondary water storage tank for drinking after flowing through an ultrafiltration water purification system. For the invention, vapor is directly collected from the surface of the sea to prepare fresh water, which omits an evaporation process, apparatus and energy consumption in a conventiona
