Air-heat deicing system

Abstract

Disclosed is an air-heat deicing system, applied to a wind turbine blade (200). The wind turbine blade is formed with a first cavity (300) and a second cavity (400), and the first cavity and the second cavity is respectively provided on both sides of a web (210). The air-heat deicing system includes: multiple wind-shields (1), a heating and blowing mechanism (2) and a pipeline mechanism (3); the multiple wind-shields (1) are provided in intervals in the first cavity (300), and the first cavity forms multiple sections (310); the heating and blowing mechanism (2) is provided in the wind turbine blade (200), and is configured to provide hot air; the pipeline mechanism (3) is connected to the heating and blowing mechanism (2), and is configured to transport the hot air to the multiple sections (310) respectively.
