[0002] The severe cold ocean environment is a serious threat to the ship's power intake system. In this environment, the intake system is prone to icing. The icing in the intake grille will change the equipment profile, increase the resistance, and affect the intake efficiency; the icing inside the filtering device will further block the intake air flow and significantly reduce the intake air volume; when the intake system is severely iced, ice may also fall off and enter the power main engine, threatening the safety of the main engine.

[0003] In the past, the anti-icing equipment mainly installed electric heating devices in the equipment of the intake system to eliminate the influence brought by icing through heating, or to prevent the intake air flow from icing by extracting high-temperature gas from the inside of the compressor and mixing it with the intake air flow. Electric heating will bring a large electric load to the ship, and bleeding air from the inside of the compressor will also reduce the engine efficiency. Summary of the Invention
