Irrigation pipes and outlet pipes.

In the working of the invention, the inlet valve on the inlet pipe is opened, and seawater is injected into the distillation room to ensure that the seawater in the distillation room is submerged by the stirring heater. When the seawater is too much, the overflow valve is opened, and the seawater is discharged through the overflow pipe. The wind power generator generates electricity under the action of wind energy. The stirring heater heats the sea water under the action of electric energy, and the sea water heats to form water vapor. The water vapor condenses on the glass cover plate, and the condensed water flows into the hollow layer of the distillation room along the inclined glass cover plate. Inside, the fresh water valve is opened, and fresh water flows out from the hollow layer to be utilized. After the seawater has been used for a period of time, the sewage valve is opened to discharge the high-concentration water and re-inject the fresh seawater. Compared with the prior art, the beneficial effects of the present invention are: the wind turbine provides electric power, one can control the stirring heater, thereby controlling the speed of seawater evaporation, and mentioning the efficiency of seawater desalination.

In order to facilitate the observation of the height of the seawater in the distillation room, a water level gauge is provided on the inner side of the inner wall of the distillation room.

In order to prevent impurities in the seawater from entering the stirring heater, the outside of the stirring heater is wrapped with a filter.

In order to facilitate the placement of the wires, the support rod is a hollow rod.

In order to facilitate the discharge of excess seawater in the distillation chamber, the overflow pipe runs through the inner and outer walls of the distillation room, below the inlet pipe, and is connected with a relief valve.

In order to facilitate the discharge of the excessively high concentration of seawater in the distillation chamber, the sewage pipe runs through the bottom surface of the distillation chamber and is connected with a drain valve.
