Anti-icing device for air inlet of ship gas turbine and using method of anti-icing device

According to the anti-icing device for the gas inlet of the ship gas turbine and the using method of the anti-icing device, the whole device is clamped and fixed to the gas turbine through a clamping type positioning connecting assembly, and then hot air is evenly blown away into a rotary control cylinder through a hot air generating assembly and an air blowing heating assembly; and meanwhile, the temperature control effect at the gas inlet of the ship gas engine is also improved, and the gas inlet of the gas engine is prevented from being frozen. 本发明公开了一种船舶燃气轮机进气口防结冰装置及其使用方法，通过夹持式定位连接组件将整个装置夹持固定在燃气轮机上，然后通过热气发生组件和吹气加热组件将热气均匀吹散在旋转控制筒内，对旋转控制筒内的湿气和霜雾进行烘干清除，同时也提高了船舶燃气机进气口处的温度控制效果，避免燃气机进气口结冰。
