Abstract
The invention relates to an anti-ice wind turbine blade adopting the microwave method. A microwave generator is mounted in the inner cavity of an ordinary wind turbine blade, and special coating absorbing the microwaves is coasted on the surface of the blade. Compared with the prior art, the anti-ice wind turbine blade has the advantages of high efficiency and low energy consumption.
Description
Technical field
The present invention relates to a kind of wind power generation blade, especially relate to the anti-extension ice of a kind of microwave method wind power generation blade.
Background technique
Wind-power electricity generation is a kind of new cleaning fuel, and energy-saving and emission-reduction are had to extremely important strategic importance.The required device of wind-power electricity generation is called wind power generating set, hereinafter to be referred as blower fan.Blower fan generally comprises blade, generator and three major components of tower cylinder.Blower fan blade surface in the time of low temperature likely can freeze, and the blade aeroperformance after freezing is understood sharp-decay, has a strong impact on the working life of generating efficiency and whole blower fan.All there is obvious defect as blowing hot-air method and low-surface-energy method in existing fan blade deicing scheme.Blowing hot-air method energy consumption is high, low-surface-energy method deicing poor effect, and freezing effect is lost in operation for 1 year afterwards substantially.Microwave ice removing is the new method of in recent years just having risen, but owing to not introducing special-purpose assorted suction microwave coating, causes microwave utilization ratio very low.
Summary of the invention
Object of the present invention is exactly to provide the anti-extension ice of microwave method that a kind of efficiency is high, energy consumption is low wind power generation blade in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions: the anti-extension ice of a kind of microwave method wind power generation blade, it is characterized in that, and at the inner chamber of common wind power generation blade, microwave oscillator is installed, and is inhaled microwave blade special coating in blade surface application.
Described suction microwave blade special coating is that Uniform Doped carbon system suction microwave material 0.1-30 weight portion makes in traditional blades coating 70-99.9 weight portion.
It is Graphene that microwave material is inhaled by described carbon system.
Described microwave oscillator is provided with at least one.
Described suction microwave blade special coating painting is contained in easy icing position or painting on blade and is contained in the whole surface of blade.
The microwave oscillator that is arranged on blade inner chamber sends microwave, and most microwave energies penetrate blade itself and arrive blade surface, arrive microwave blade special coating.This coating will absorb most microwave energies, and microwave is converted into heat energy.This part heat energy will be absorbed by the ice sheet that meets place of boundary with coating, and then the ice sheet that meets place of boundary is melted fast as water, finally makes whole ice sheet come off, and reaches deicing object.If this special-purpose coat does not match, most of microwave will evenly be absorbed by blade surface ice sheet, and the ice sheet melting rate that meets place of boundary with coating can obviously reduce, and deicing energy consumption improves greatly.
Compared with prior art, the present invention has the following advantages:
One, the effective absorption efficiency of microwave is high, reduces deicing energy consumption.If do not have microwave blade special coating to match, most of microwave will evenly be absorbed by blade surface ice sheet, and the ice sheet melting rate that meets place of boundary with coating can obviously reduce, and deicing energy consumption improves greatly.
Two, deicing efficiency is high, and the deicing time is short.This invention can absorb microwave fast, thereby melts fast ice sheet and make it to come off, and greatly reduces the deicing time.
