The invention relates to the field of airplane wing ice prevention and removal, in particular to an airplane wing surface backflow ice prevention and removal system. The system comprises an engine air-entraining anti-icing and de-icing system, an icing detector and a backflow ice anti-icing and de-icing device. The air-entraining anti-icing and de-icing system for the engine comprises an intersection valve, an anti-icing valve, an air supply pipe, a flute-shaped pipe, a flexible joint and a T-shaped pipe, the icing detector is used for detecting the ice type and the icing degree and feeding back the ice type and the icing degree to the anti-icing and deicing system; the backflow ice preventing and removing device is composed of a rolling device, an air entraining spray head, an air entraining connector, an air entraining valve, an air entraining pipeline, a steering shaft, a rolling wheel, a spray head base, a left spar, a guide rail and a spar flexible air supply pipe. And reflow ice formed outside a thermal protection area after the leading edge of the wing is iced in the engine bleed air system is removed. According to the invention, more nozzles do not need to be installed, and backflow ice is efficiently eliminated on the basis of effectively reducing the weight of an anti-icing and deicing system.
