At present, the deicing and preventing of wind turbine blades mainly stays in a deicing stage, the deicing technology is mainly in an artificial deicing mode, few enterprises can also utilize unmanned planes to assist in deicing, but the deicing is a remedial measure after the formation of ice coating, and the deicing is the most fundamental preventive measure.
At present, the anti-icing means is mainly implemented by spraying a hydrophobic coating on the surface of the blade, the purpose of the spraying of the hydrophobic coating is to reduce the condensation of water vapor on the surface of the blade, so as to hinder the generation of icing, however, the hydrophobicity of the hydrophobic coating gradually decreases with the increase of time, so the anti-icing aging is usually short, and the practical application effect of the anti-icing technology is not ideal.
In addition, when the ice on the surface of the blade needs to be removed, the operation of the wind turbine must be stopped, and the wind turbine is restarted after the ice removal is finished, so that the power generation efficiency of the wind turbine is sacrificed in each deicing operation, and if the freezing weather is not finished, the ice on the surface of the blade is quickly formed again, so that the ice removal operation can be continuously performed on the surface of the blade, and the deicing cost is high.

When large-scale wind generating set meets low temperature congeals and freezes the weather, ambient temperature can reduce fast, can lead to the synchronous decline of the temperature of outer blade body 1, can produce certain difference in temperature between the atmospheric environment in microwave reflection chamber 7 that can make outer blade body 1 inboard and the outer blade body 1 outside, and the temperature in the microwave reflection chamber 7 can be higher than the atmospheric environment in the outer blade body 1 outside, the water droplet can be condensed into gradually at outer blade body 1 internal surface to the relative warm vapor in microwave reflection chamber 7 this moment, because the hydrophilic coating 6 of marsh gas sediment carbon has been add to outer blade body 1 internal surface, consequently can be through the better lock of the water droplet of marsh gas sediment carbon hydrophilic coating 6 with condensing at outer blade body 1 internal surface.

For the blade surface which is not formed with ice coating, the condensation of water vapor in the environment on the blade surface can be prevented or slowed down by heating the blade, so that the anti-icing function is realized. For the blade surface with formed ice coating, the ice coating can be gradually melted by heating the blade, thereby realizing the deicing function. In addition, in the process of ice prevention and removal, the method can be implemented under the condition that the wind turbine does not stop, so that the power generation efficiency of the wind turbine is greatly improved, and the ice prevention and removal cost is effectively reduced.
