Description
Technical Field
The utility model relates to the technical field of wind power generation, in particular to a high-efficiency deicing device for a wind power blade.
Background
Wind energy distribution in China is not uniform, and a large amount of wind energy is mainly concentrated in open areas with very cold climates such as northeast, northwest and north China. These areas are in the place where cold air invades first, causing the possibility of icing of the blades of the wind driven generator in winter and spring in two seasons each year. In the middle and lower reaches of the Yangtze river such as Hunan, Hubei, Jiangxi and Zhejiang, blade icing can also occur in the environment with lower temperature in winter due to sufficient water vapor.
After the surface of the blade of the wind driven generator is coated with ice, the wing profile of the blade is irregularly changed, the height of the surface of the blade is uneven, the roughness is increased, the lift force of the blade of the fan is reduced, the resistance is increased, the aerodynamic performance is reduced, the rotating speed is finally reduced or stopped, the wind energy utilization rate is reduced, the power generation cannot be stabilized, and the stable operation of a power system is influenced.
In the related art, surface solution anti-icing is generally adopted, and the freezing point of the solution is lowered by coating anti-icing liquid on an easily-icing surface, namely, solution anti-icing. The anti-icing fluid such as ethanol, ethylene glycol, propylene glycol and the like is coated on the blades of the wind driven generator, and the anti-icing fluid is mixed with supercooled water drops captured by the blades in the rotating process of the blades to reduce the freezing point of the solution so as to reduce the icing possibility.
Electric heating anti-icing, through changing the electric energy into heat energy, heat the part that needs protect in advance to a method of preventing it from freezing, what has generally adopted at present is that the pre-buried resistance wire in blade top layer, circular telegram makes it generate heat when low temperature, however this method needs to be pre-buried when the blade produces, only is applicable to newly-built wind farm, influences the whole lightning protection effect of unit, has great potential safety hazard, and damage the after-maintenance difficulty, can't use in the wind farm transformation that has already put into use.
The coating is used for preventing ice, a certain special coating with certain characteristics is coated on the blade of the wind driven generator, the adhesion between an ice layer and the blade is reduced or the ice is melted by utilizing the characteristics of the coating, and the aim of removing the ice is achieved.
Blowing air to prevent ice, and utilizing air flow to organize the icing on the surface of the blade. And a plurality of rows of air outlets are arranged at the positions close to the front edges of the blades, which are easy to be coated with ice, air is discharged from the air outlets, and a layer of airflow layer is formed on the surface of the blades. Most water droplets striking the blades may be deflected in trajectory away from the blades as they pass through the air flow layer, and a few water droplets that settle on the blades may be melted by the air flow, thereby reducing the potential for icing. However, the uneven air flow at the exhaust port in the method can cause uneven anti-icing effect, and the farther the position is from the exhaust port, the better the anti-icing effect is, and finally the anti-icing effect is poor, so that the method cannot be applied to the reconstruction of the wind field which is put into use.
