Wind power blade deicing device and deicing method

Abstract

The invention belongs to the field of wind power generation treatment and particularly relates to a wind power blade deicing device and a method performing deicing through the device. The device comprises a wind power generator part, a heat preserving control part, a hot air spraying and blowing part and a water vapor treatment part. Due to the fact that the various parts are specifically limited,the purpose that in a local heat preserving area, hot air rich in water vapor and ethyl alcohol steam is sprayed and blown on a wind power blade for deicing is achieved, and a relatively low cost anda good deicing effect are achieved.

Description

technical field [0001] The invention belongs to the field of clean energy, in particular to the field of wind power generation devices and processing methods, in particular to a wind power blade deicing device and a deicing method. Background technique [0002] The hazard of icing on the blades of wind power generation has become a very important negative factor that affects the power generation efficiency of wind turbines and the life of wind turbines. At present, researchers mainly use thermal ablation to melt and remove the ice layer on the outer surface of wind power blades, and this thermal ablation mainly includes the method of setting the cavity inside to feed the hot solution, the method of laying resistance wires inside the blade, and the The way of laying resistance wire externally. However, the way of the cavity will not only cause the stress concentration of the wind power blades, but also cause the ice layer on some parts of the blade to be unable to be effecti...

Problems solved by technology

However, the way of the cavity will not only cause the stress concentration of the wind power blades, but also cause the ice layer on some parts of the blade to be unable to be effectively removed due to the incomplete coverage of the cavity; the way of setting the resistance wire inside the blade is not only The process increases the difficulty and cost, and the effectiveness of the resistance wire cannot be guaranteed. At the same time, due to the incomplete layout method, the ice layer on some parts of the blade cannot be effectively removed; and the way of setting the resistance wire outside the blade, the resistance wire is very Vulnerable to damage, effectiveness cannot be guaranteed

There are also some studies to apply anti-icing coatings to the outer surface of the blades, but because the outer surfaces of wind turbine blades have been eroded by wind and sand for a long time, the coatings are very vulnerable to damage, and the composition of the coatings is relatively high.
