The air inlet device for the high-efficiency noise elimination of the air purification comprises an air inlet cavity, filter cylinders, a blowback cavity and a blowback system, the blowback system is arranged in the blowback cavity, and the blowback system comprises blowback pipes; the center line of each blowback pipe and the center line of the corresponding filter cylinder are in the same straight line; each filter cylinder comprises a filter cylinder framework, wherein the filter cylinder framework is composed of an outer metal mesh layer and an inner metal mesh layer; a cylindrical filter cylinder framework surrounded by three sides is composed of the outer metal mesh layer and the inner metal mesh layer, and a filter layer is arranged between the outer metal mesh layer and the inner metal mesh layer; a sealed end cap is provided with a breather pipe communicated with the interior of the filter cylinder framework, and one end of the breather pipe penetrates the sealed end cap to be extended into the filter cylinder framework; the bottom of the breather pipe is connected with a gas distribution disk, and gas distribution holes communicated with the breather pipe are formed in the bottom surface and the side surface of the gas distribution disk; gas distribution holes are formed in the side wall of the breather pipe; and noise elimination modules are arranged in the air inlet cavity.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and specifically relates to an air intake device for air purification and high-efficiency noise reduction, which is used for filtering and purifying the air introduced into the gas turbine. Meanwhile, the invention can also be used for air filtration and purification 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-te...
