Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a high-efficiency and energy-saving rotor-type noise-eliminating air filter device for filtering air entering a gas turbine. The invention can also be used for air purification and filtration in other fields. Background technique [0002] A gas turbine is a rotary power machine that converts heat energy into mechanical work using continuously flowing gas as a working medium. In the main process of air and gas, the gas turbine cycle is mainly composed of three major components: the compressor, the combustion chamber and the gas turbine. [0003] The compressor inhales air from the external atmosphere, and pressurizes it step by step through the axial flow compressor, and the air humidity is also increased accordingly; the compressed air is sent to the combustion chamber to mix with the injected fuel to produce high-temperature and high-pressure gas Then enter the...
