Example Embodiment
[0036] Example 1
[0037] See figure 1 with figure 2 As shown, the embodiment of the present invention provides an evaporation device that uses multiple physical fields for high-speed evaporation, including an evaporation layer, a hydrophobic heat insulation layer 2 and a power supply device 3. The evaporation layer is configured to have heating and hydrophilic properties, and the evaporation The layer is used to extend into the water to be treated, the hydrophobic heat insulation layer 2 is provided at the bottom of the evaporation layer, and the power supply device 3 is connected to the evaporation layer. Furthermore, the evaporation layer includes a heating layer 11 and a hydrophilic layer 12, and the heating layer 11 And / or light energy is converted into heat energy, the hydrophilic layer 12 is attached to one side of the heating layer 11, and the hydrophilic layer 12 is used to extend to the water to be treated and conduct the water to be treated to a position in contact wit...

[0043] Example 2
[0044] See image 3 As shown, an embodiment of the present invention provides an evaporation system, including:
[0045] The evaporation chamber 4 is provided with the evaporation device 9 and the light-transmitting area 31 of the above-mentioned embodiment 1, the light-transmitting area and the evaporation device 9 are arranged directly opposite, and the light-transmitting area is used to transmit sunlight;
[0046] The first water storage tank 5 is connected to the evaporation chamber 4, and the first water storage tank 5 is used to store the water to be treated;
[0047] Condensation heat exchange chamber 6, which is in communication with evaporation chamber 4;
[0048] The second water storage tank 7 communicates with the bottom of the condensation heat exchange chamber 6;
[0049] The negative pressure generating device 8 is used to adjust the pressure in the evaporation chamber 4. Preferably, the negative pressure generating device 8 is a vacuum pump.

Example Embodiment
[0052] Example 3
[0053] On the basis of embodiment 2, in this embodiment, the heating layer 11 is carbon cloth, the hydrophilic layer 12 is hydrophilic fiber cloth, and the hydrophobic heat insulation layer 2 is polystyrene foam, in which the hydrophilic fiber cloth is covered Hydrophobic and heat-insulating polystyrene foam, connect the two ends of the carbon cloth with platinum electrodes to the power supply device 3, and make the heating part of the carbon cloth closely contact the hydrophilic fiber cloth by bonding, and keep the carbon cloth face up. It is placed in the sea water to be treated.
[0054] When the seawater is desalinated through the evaporation system, the radiation intensity is 1kW / m under normal light AM 1.5G 2 Under light conditions, without electric field and negative pressure (the power supply device 3 does not supply power, and the negative pressure generator 8 has no effect), the desalination rate of seawater can reach 1.5kg m -2 h -1 ; Under normal ligh...
