Description

Wind electricity blade anti-freeze control system and its wind electricity blade with deicing properties Preparation method
Technical field
The present invention relates to a kind of wind electricity blade is and in particular to the anti-freeze control system of a kind of wind electricity blade and its have anti-caking The preparation method of the wind electricity blade of ice performance.
Background technology
Wind energy, as an important branch of new forms of energy, with its cleaning, safe and stable feature, is widely paid close attention to. Wind turbines are the devices converting wind energy into electric energy, and wherein fan blade is as one of the core component of Wind turbines, its matter Amount directly affects the quality of Wind turbines, and the fast development with domestic and international megawatt of grade blade, and blade generated output is increasingly Greatly, blade is also more and more longer, and the requirement to Blade Properties and quality is also more and more high.In severe cold weather, fan blade is running During easily freeze.Test result indicate that, fan blade profile icing initial position occurs mainly in blade inlet edge, in blade root Place's icing amount is less, and launches to two weeks mainly around blade root aerofoil profile, and main ice forming locations are still at mid blade and blade tip. Overlay area is concentrated mainly on the downside in datum level leading edge stationary point, reflects on blade to be exactly blade and flow field under certain angle of attack The trailing edge of contact and lower edge.And from blade root to blade tip, icing amount constantly increases.Under identical wind speed, with the increasing of drop diameter Greatly, icing amount is also continuously increased, and heating deicing is the effective way solving this problem.The mode of heating deicing at present mainly has two Kind: gas full-boiled process and electrothermal way.Gas full-boiled process using leading to hot-air in circulation canal, or blade inner chamber install fixing micro- Wave producer, carries out deicing using microwave energy heating composite.The method is limited by blade construction, needs heat Windward side is little because of the heat conductivity of material, especially undesirable to large-scale blade deicing effect.If heating-up temperature is too high, to blade institute Had higher requirements with the heat distortion temperature of resin, be difficult to promote in practice.And electrical heating method there is presently no preferably It is applied to heating in fan blade.
