The invention discloses an embedded solar
seawater distilling device based on light condensation
direct heating. The device is characterized in that a
light reflection circular truncated cone is installed in the center of a heating water tank, a light condensation funnel and a throwing
light guide device are installed above the heating water tank, and a heat preservation material is arranged at the bottom of the heating water tank; an area between a circular truncated cone sleeve and the heating water tank is an
evaporation condensation cavity. Feeding
seawater passes through heat exchange coil pipes arranged in a
fresh water tank and a concentrated
seawater tank under driving of a water pump in sequence and then enters the
evaporation condensation cavity, the wall face of a hydrophilic material is sprayed after the feeding seawater passes through the
evaporation condensation cavity, a water film is formed under the effect of water stopping grooves, and water in the heating water tankabsorbs energy so that the temperature of the water can be increased. The water film is heated and evaporated to form vapor, and the vapor is condensed to form
fresh water on the wall face of the side, with low temperature, of the
evaporation condensation cavity; finally, the non-evaporated seawater enters the concentrated seawater tank, and the
fresh water enters the fresh water tank. By integrating the
solar heat collection part and the sweater distilling desalting part, the device has the advantages of being compact in structure, small in occupation floor, capable of achieving efficient
coupling of seawater
evaporation temperature and heat collection temperature of a condenser and the like.
