Background
When a large-scale wind generating set is erected in a high-altitude mountain area and is influenced by local climate conditions, the wind turbine blade is particularly easy to form surface ice coating in low-temperature freezing weather, the shape of the blade can be changed due to the existence of the ice coating, the lift force of the blade is further reduced, the power generation of the wind generating set is greatly reduced, and even the wind turbine is stopped, so that serious economic loss is generated.
At present, the anti-icing and deicing of the wind turbine blade mainly stays in the deicing stage, the deicing technology is mainly a manual deicing mode, few enterprises can also utilize unmanned aerial vehicles to assist in deicing, but the deicing is a remedial measure after the formation of ice coating, and the anti-icing is the most fundamental preventive measure.
At present, the anti-icing means is mainly implemented in a mode of spraying hydrophobic coating on the surface of the blade, the purpose of spraying the hydrophobic coating is to reduce condensation of water vapor on the surface of the blade, so that the generation of icing is hindered, however, the hydrophobicity of the hydrophobic coating gradually decreases with the increase of time, so that the anti-icing aging is generally shorter, and the practical application effect of the anti-icing technology is not ideal.
In addition, when the icing on the surface of the blade is required to be removed, the operation of the wind turbine is required to be stopped first, and then the wind turbine is restarted after deicing is finished, so that the power generation efficiency of the wind turbine is sacrificed for each deicing operation, and if the freezing weather is not finished, the icing on the surface of the blade is formed again quickly, and therefore, the deicing operation can only be continuously performed on the surface of the blade, and the deicing cost is high.

The manufacturing method of the biogas residue carbon hydrophilic coating 6 comprises the following steps:
step one: a200 ml portion of distilled water was prepared, and then 2g of dopamine hydrochloride (C) 8 H 11 NO 2 HCl), then carrying out an ice-water bath ultrasonic homogenization treatment on the aqueous solution;
step two: another 100ml of distilled water was prepared, then 1.2g of Tris (hydroxymethyl) aminomethane (Tris) was added to the distilled water, and then the aqueous solution was subjected to ice-water bath ultrasonic homogenization;
step three: adding 1g of biogas residue carbon into the water solution subjected to the ice water bath ultrasonic homogenization treatment in the first step, and then carrying out ice water bath ultrasonic homogenization treatment on the water solution;
step four: mixing the water solution subjected to ice water bath ultrasonic homogenization treatment in the second step with the water solution subjected to ice water bath ultrasonic homogenization treatment in the third step, stirring the mixed water solution at room temperature (20 ℃) for 10 hours, centrifuging the stirred water solution to obtain a centrifugal separator of a carbon and dopamine mixture (C@PDA), washing the carbon and dopamine mixture (C@PDA) by using ethanol, and finally drying the washed carbon and dopamine mixture (C@PDA) at 60 ℃ for 24 hours;
step five: preparing a part of N, N-dimethylacetamide (DMAc) solution, adding the dried mixture of carbon and dopamine (C@PDA) obtained in the fourth step to the N, N-dimethylacetamide (DMAc) solution, and performing ultrasonic homogenization treatment on the solution for 1 h;
step six: adding Polysulfone (PSF) into the solution subjected to ultrasonic homogenization treatment in the fifth step, heating and stirring the solution until the Polysulfone (PSF) is completely dissolved into the solution to form a pasty coating, and finally standing the obtained pasty coating for 24 hours for defoaming to obtain the biogas residue carbon hydrophilic coating;
step seven: preparing a sufficient amount of biogas residue carbon hydrophilic coating according to the inner surface area of the outer layer blade body 1 and referring to the processes from the first step to the sixth step;
step eight: preparing a glass plate, smearing the biogas residue carbon hydrophilic coating prepared in the step seven on the glass plate, scraping the biogas residue carbon hydrophilic coating to form a film, cutting and dividing the biogas residue carbon hydrophilic coating film after the film is formed, and finally paving the biogas residue carbon hydrophilic coating film on the inner surface of the outer layer blade body 1 by pieces through sodium silicate alginate until the biogas residue carbon hydrophilic coating 6 is formed.
In this embodiment, the outer layer blade body 1 and the inner layer blade body 2 are made of glass fiber reinforced plastic, the microwave frequency of the microwave generator 3 is set to 2450MHz, and the microwave reflecting layer 5 is made of aluminum foil.
When a large wind generating set encounters low-temperature freezing weather, the environment temperature can be reduced rapidly, the temperature of the outer layer blade body 1 can be reduced synchronously, a certain temperature difference can be generated between the microwave reflection cavity 7 on the inner side of the outer layer blade body 1 and the atmospheric environment on the outer side of the outer layer blade body 1, the temperature in the microwave reflection cavity 7 can be higher than the atmospheric environment on the outer side of the outer layer blade body 1, at the moment, relatively warm water vapor in the microwave reflection cavity 7 can be gradually condensed into water drops on the inner surface of the outer layer blade body 1, and as the biogas residue carbon hydrophilic coating 6 is additionally arranged on the inner surface of the outer layer blade body 1, condensed water drops can be better locked on the inner surface of the outer layer blade body 1 through the biogas residue carbon hydrophilic coating 6.
When the surface of the blade does not form ice coating, the microwave generator 3 can be started to realize the anti-icing function, and when the surface of the blade forms ice coating, the microwave generator 3 can be started to realize the deicing function. Specifically, after the microwave generator 3 is started, the generated microwave radiation enters the microwave reflecting cavity 7 through the microwave transmission waveguide 4, the whole microwave reflecting cavity 7 is filled with the microwave radiation under the reflecting action of the microwave reflecting layer 5, and when the moisture absorbed in the biogas residue carbon hydrophilic coating 6 is subjected to the action of the microwave radiation, the moisture is gradually heated, and the generated heat is synchronously transmitted to the outer-layer blade body 1, so that the temperature of the outer-layer blade body 1 is increased. For the surface of the blade which does not form ice coating, the condensation of water vapor in the environment on the surface of the blade can be prevented or slowed down by heating the blade, so that the anti-icing function is realized. For the surface of the blade on which the ice coating has been formed, the ice coating can be gradually melted by heating the blade, thereby realizing the deicing function. In addition, in the process of preventing and removing ice, the method can be implemented under the condition that the wind turbine is not stopped, so that the power generation efficiency of the wind turbine is greatly improved, and the cost of preventing and removing ice is effectively reduced.
The embodiments are not intended to limit the scope of the invention, but rather are intended to cover all equivalent implementations or modifications that can be made without departing from the scope of the invention.
