The invention discloses an evaporation device and an evaporation system for high-speed evaporation with multiple physical fields and relates to the technical field of desalted water preparation. The evaporation device comprises an evaporation layer, a hydrophobic thermal-insulating layer and a power supply device, wherein the evaporation layer comprises a heating layer and a hydrophilic layer; theheating layer is used for converting electric energy and/or optical energy into heat energy; the hydrophilic layer is adhered to one side surface of the heating layer; the hydrophilic layer extends into water to be treated and is used for conducting the water to be treated to a position contacting with the heating layer; the hydrophobic thermal-insulating layer is fixed with the bottom of the evaporation layer and is positioned below the heating layer; and the power supply device is connected with the heating layer. The evaporation system is constructed by putting the evaporation device in anegative pressure environment and comprises a condensation heat exchange device. By adopting the evaporation device and the evaporation system, the evaporation velocity of seawater desalting can be increased.
