The working principle of this embodiment is as follows:
under the drive of a fan 15, the compressor 12 runs at a high speed, the compressor compresses and heats the wet air in the floating island shell, the compressed wet air with the temperature of about 150 ℃ is subjected to heat dissipation and cooling through the spiral pipe heat exchanger 2, and fresh water begins to be separated out after the wet air reaches the dew point temperature; the sensible heat of air cooling and the latent heat of moisture condensation release heat to continuously heat the seawater in the floating island shell through the spiral pipe heat exchanger, and the temperature of the seawater is gradually increased. The steam-water mixture at the outlet of the spiral tube heat exchanger enters the fresh water tank 3, after the steam-water separation effect, fresh water falls into the fresh water tank, high-pressure air enters the ejector 7 through the one-way valve 6, high-speed air is introduced into the air at the top of the floating island shell through the Venturi effect, the air at the outlet of the ejector is introduced into the sea water through the aeration disc 8, the air is guided by the guide cylinder 9 in the sea water rising process, and due to the fact that the gas phase content inside and outside the guide cylinder is different (the gas phase content inside the guide cylinder is high, the gas phase content outside the guide cylinder is low), the sea water forms a three-dimensional annular flow as shown in fig. 3 under the effect of the density difference of the sea water inside and outside the guide cylinder, and the circulating sea water continuously washes the outer wall surface of the spiral tube heat exchanger, so that the heat exchange efficiency of the spiral tube heat exchanger is improved. In the process that the air bubbles float in the seawater, as the water vapor partial pressure of the seawater is far greater than that of the wet air, a large amount of water molecules migrate into the bubbles on the 'gas-liquid' boundary layer of the bubbles, so that the wet air carried by the circulating air in the seawater is carried by the circulating air, and the wet air carried by the circulating air enters the compressor again and starts to circulate in the next period.
After the system stably operates, the seawater in the floating island shell has certain temperature gradient distribution up and down, the temperature of the seawater at the upper layer can reach 60-70 ℃, and the temperature of the seawater at the lower part of the floating island shell is 30-40 ℃; the relative humidity of circulating air overflowed from seawater reaches 100% through the injection circulation of the jet pump, and the carrying capacity of the LC43 type compressor under the rated working condition (980 rpm) is 1.44kg water/s; the dehumidified air was cooled to 35℃in a spiral tube heat exchanger to a humidity of 1.25kg/s, i.e. the system of this example produced a maximum of 4.5t fresh water per hour.
When the embodiment operates, the liquid level of the floating island shell is regulated by the amount of air reserves in the floating island shell, and when the liquid level is too low, the exhaust valve 13 of the compressor outlet is opened, so that the air amount in the floating island shell is reduced; when the liquid level is too high, the suction valve 11 of the air inlet of the compressor is opened, and the air quantity in the floating island shell is increased.
In the embodiment, the coupling type wind power system is adopted as the driving energy of the sea water desalination system, and compared with a separation type wind power system, the sea water desalination system does not need expensive power generation equipment, the system directly converts wind energy into mechanical energy required by the operation of a compressor, the energy conversion efficiency is high, and the initial equipment investment is small; the sea water desalination is realized by adopting the compressed air high-temperature humidity carrying technical principle, and the system energy utilization is reasonable and efficient.
