Title:
CARBON CRYSTAL ANTI-ICING METHOD AND WIND DRIVEN GENERATOR ANTI-ICING SYSTEM EMPLOYING SAME
Document Type and Number:
WIPO Patent Application WO/2014/173043
Kind Code:
A1
Abstract:
A carbon crystal anti-icing method. The method comprises: printing nanosized conductive carbon crystal on a carrier, preparing a thin carbon crystal electric hot plate with two electrodes by means of curing and hot-pressing technologies, laying the carbon crystal electric hot plate on a surface layer or secondary surface layer of a blade to form a heating layer (5), dividing the heating layer (5) into a plurality of heating areas, performing temperature raising control in each heating area by using a heating controller by on-line temperature monitoring, and keeping a temperature of an outer surface of the anti-icing heating area higher than and approximate to 0 degree Celsius. The heating controller can control the heating areas to work simultaneously or alternately, to perform automatic ice prevention or ice melting. Further disclosed is a wind driven generator anti-icing system employing the method. A carbon crystal electric hot plate is used as an electric heating material of an anti-icing blade, so that a manufacturing technology of the anti-icing system is simple, anti-icing heating is uniform, and structure strength of the blade is also enhanced; in addition, an on-line temperature monitoring closed-loop control is performed, so that the anti-icing system is stable, safe, and energy-saving.
