The seawater supply system composed of seawater spray pipes and seawater circulation pumps also includes seawater evaporation tanks and freshwater condensation tanks arranged side by side. Above the horizontal pipe of the device, there is a concentrated brine pipe at the bottom of the seawater evaporation tank. The seawater circulation pipe is arranged in the fresh water condensation tank. The suction holes communicate with each other, and a fresh water outlet pipe is arranged at the bottom of the fresh water condensation tank.

The seawater circulation pipe, after being heated and evaporated by the horizontal horizontal pipe of the desalination device in the seawater evaporation box, reaches the freshwater condensation box through the suction hole, and is condensed by the seawater circulation pipe to form fresh water, which is released from the fresh water outlet pipe when needed. The solar horizontal pipe of this structure The tube falling film evaporation seawater desalination device is small in size, low in cost, and consumes little non-solar energy for desalinating seawater. It can effectively solve the fresh water supply in places where the amount of fresh water is small, such as islands and ships, and has a wide range of applications; seawater evaporation tanks and fresh water The condensing tanks are arranged side by side, and only communicated with the air extraction hole. This structure can better isolate the heat exchange between each other, make the evaporation effect of seawater and the condensation effect of water vapor better, and reduce the center of gravity, and resist Wind power increased.
