Abstract
A modular gas-heat anti-icing method as well as a device for high-power wind turbine blades, wherein a modular heating system is provided on the blade root, a ventilation duct is provided inside the blade, a wind deflector is provided at the end of the ventilation duct, which divides the front edge of the blade into two parts, so that the hot air in the ventilation duct is only to be conducted to the blade tip and then circulates into the blade root via the rear edge of the blade, enabling the hot air to circulate inside the blade and form a 'blade root to blade tip to blade root' closed loop, so that the purpose of heating the front edge of the blade is achieved, and it is ensured that the whole blade does not ice by preventing the front edge of the blade from icing.
