A solar energy sea water desalination device relates to a solar energy sea water desalination device for producing water, a floating device provides buoyancy, a water absorption material in the floating device absorbs sea water into an evaporation chamber to form a water film above the floating device, and the water film receives sunlight penetrating through a spherical surface film and is heated to form water vapor; when enough water vapor is in the evaporation chamber (the pressure intensity is increased), the water vapor enters the water storage bag floating in the seawater through the copper pipe, the water storage bag is bent and passes through the copper pipe, and the water absorbing material covers the outer side of the copper pipe, so that the water vapor in the copper pipe transfers heat to the water absorbing material at the outer side as much as possible, and most of the water vapor is cooled into water in the copper pipe and flows down to the water storage bag; the temperature in the water storage bag is lower, and drinkable fresh water is generated by cooling. The spherical surface film is made of transparent material, so that the weight of the device is reduced; the water storage bag is suspended in seawater, and the stress of the device is not changed by the addition of the condensed water; the device can be large or small, and is easy to use in large scale. |
